Assa'edah Mahmud A, Zakaria H, Zaliman Mohd Yusoff M, Ruzyanei Nik Jaafar N, Baharudin A, Mohd Tamil A

Alpha Psychiatry, 2022 Sep;23(5):223-229.
PMID: 36426271 DOI: 10.5152/alphapsychiatry.2022.21781

BACKGROUND: The primary purpose of this study is to examine the feasibility of a short-term virtual reality exposure therapy among healthy working adults sample. The secondary aim is to measure the effect of virtual reality exposure therapy on negative and positive emotions by comparing it to the standard stress management program and the wait-list groups.
METHODS: We enrolled 67 participants allocated into 3 groups to receive virtual reality exposure therapy, standard stress management, or wait-list group. The virtual reality exposure therapy group received a total of a 30-minute exposure to a virtual reality environment over 2 weeks. The standard stress management group received a stress management program once during the study period.
RESULTS: The results showed a heterogeneous sample, whereby a significantly younger, less-working years, and higher anxiety baseline score were found in the virtual reality exposure therapy group compared to standard stress management and wait-list groups. Nonetheless, the virtual reality exposure therapy group showed a reduction in depression, anxiety, and stress score (P < .001). The standard stress management group showed a reduction in anxiety score only (P = .002), whereas no significant changes were observed in the wait-list group. For positive emotion, all 3 groups showed significant improvement.
CONCLUSION: Short-term virtual reality exposure therapy is a feasible intervention for the negative and positive emotions; however, cautious interpretation is needed due to significant heterogeneous sample. Replication of study with comparable groups is recommended.
Knowledge and attitude on sex among medical students of a Malaysian university: a comparison study

Sidi H, Loh SF, Mahadevan R, Puteh SE, Musa R, Wong CY, et al.

Asia Pac Psychiatry, 2013 Apr;5 Suppl 1:103-9.
PMID: 23857845 DOI: 10.1111/appy.12053

INTRODUCTION: The objective of this study was to determine the relationship between clinical/socio-demographic factors with knowledge and attitude on sex among medical students of the National University of Malaysia (UKM).
METHODS: A cross-sectional study assessing 452 students using a self-administered questionnaire of knowledge and attitude was performed and had a response rate of 80%.
RESULTS: The majority of respondents were Malays (56%), females (57.5%), lived in urban areas (66.4%), had a median family income of RM3000 and perceived themselves as moderately religious (60%). The overall score on knowledge about sex was 21.7 of 35 (a higher score indicates better knowledge about sex). It was noted that 73.2% of students felt that they did not receive adequate training in medical school to deal with patients' sexuality and sexual problems, while 51.5% felt uncomfortable talking to patients about these issues. Students in the clinical year were more knowledgeable than those in pre-clinical years (22.67 versus 20.71, P 22 marks [median score]).
DISCUSSION: The students' attitude on sex was considered conservative as the majority of them disagreed on premarital sex, masturbation, abortion, homosexuality and oral sex. Gender and religiosity have a large influence on attitudes on controversial sexual issues, whereas clinical status plays a small role. Knowledge on sex among UKM medical students is inadequate and their attitudes on sex are considered conservative. Integration of sexual medicine and health modules in the medical curriculum is crucial for students to more effectively address patients' sexual problems and promote non-judgmental attitudes towards patients.

Selamat Din SH, Nik Jaafar NR, Zakaria H, Mohamed Saini S, Ahmad SN, Midin M

Asian Pac J Cancer Prev, 2017 Feb 01;18(2):465-471.
PMID: 28345831

Background: Anxiety is recognized as a normal psychological reaction of those caring for cancer patients. However, anxiety disorders in caregivers may interfere with their care-giving role and require further clinical attention. Objectives: To determine the prevalence and associated factors of anxiety disorders among caregivers of breast cancer patients receiving oncologic treatment in Kuala Lumpur Hospital. Methodology: A cross-sectional study was conducted on 130 caregiver-patient dyads, recruited by non-random sampling at Kuala Lumpur Hospital. Data were collected in 2 stages: 1) the caregivers were screened for psychological distress using the Depression, Anxiety, Stress, Scale (DASS-21) while other related factors for the patients and their caregivers were obtained; 2) the identified distressed caregivers (n=64) were then administered the Mini International Neuropsychiatric Interview (MINI) to diagnose anxiety disorders. Results: A total of 11.5% (n=15) of the caregivers reported suffering from anxiety disorders. Bivariate analysis found duration of caregiving (OR=3.31; CI=2.21-11.93), shared caregiving (OR=4.07; CI=1.34-12.36), and patients’ treatment type (OR=3.42; CI=1.92-12.76) were significantly associated with anxiety disorders (p value <0.05), with shared caregiving and patient’s treatment type remaining significant using logistic regression (p value < 0.05, R2 = 0.255). Conclusions: Every one in ten of the caregivers in this study had a diagnosable anxiety disorder, associated with certain care-giving factors and patients’ treatment. This should alert clinicians to such risk and indicates psychological support needs for family caregivers.
Fulltext Reducing the stigma of mental health disorders with a focus on low- and middle-income countries

Javed A, Lee C, Zakaria H, Buenaventura RD, Cetkovich-Bakmas M, Duailibi K, et al.

Asian J Psychiatr, 2021 Apr;58:102601.

Mental health disorders are a burgeoning global public health challenge, and disproportionately affect the poor. Low- and middle-income countries (LMICs) bear 80 % of the mental health disease burden. Stigma associated with mental health results in delayed help seeking, reduced access to health services, suboptimal treatment, poor outcomes and an increased risk of individuals' human rights violations. Moreover, widespread co-occurrence of physical comorbidities such as noncommunicable diseases with mental health disorders makes the treatment of both conditions challenging and worsens prognosis. This paper explores various aspects of stigma towards mental health with a focus on LMICs and assesses measures to increase help-seeking and access to and uptake of mental health services. Stigma impacts persons living with mental illness, their families and caregivers and healthcare professionals (mental health professionals, non-psychiatric specialists and general practitioners) imparting mental health care. Cultural, socio-economic and religious factors determine various aspects of mental health in LMICs, ranging from perceptions of health and illness, health seeking behavior, attitudes of the individuals and health practitioners and mental health systems. Addressing stigma requires comprehensive and inclusive mental health policies and legislations; sustainable and culturally-adapted awareness programs; capacity building of mental health workforce through task-shifting and interprofessional approaches; and improved access to mental health services by integration with primary healthcare and utilizing existing pathways of care. Future strategies targeting stigma reduction must consider the enormous physical comorbidity burden associated with mental health, prioritize workplace interventions and importantly, address the deterioration of population mental health from the COVID-19 pandemic.

Sexuality is an important dimension in human beings as a form of expression of individuality. For many decades, sexual functioning has been a neglected area among patients suffering from schizophrenia. It was a presumption that patients with schizophrenia could be asexual and this could be secondary to overwhelming situations of delusion, hallucination, hostility and negative symptoms among others. The deficient in sexual functioning are due to innate factors, i.e. negative symptoms (apathy, avolition and amotivation) and also as a result of prefrontal dysfunction, i.e. inability to plan and execute meaningful relationship. Adverse effects of the psychopharmacological agents, especially the typical antipsychotics, e.g. dystonia, excessive sedation and hyperprolactinemia may interfere with patients' sexual activity. In this review, we highlight the neurobiology of schizophrenia in the context of understanding sexual functioning and to integrate the knowledge of dopamine-serotonin neurotransmitter's interaction and the receptors' target. Interventional approaches consist of psychopharmacological and psychosocial interventions. In the perspective of sexuality, we recommend atypical antipsychotic should be placed as the first line treatment for both drug naïve patients and also to patients who are already receiving psychopharmacological agents in consideration for a drug-switch from typical to atypical antipsychotics. Aripiprazole, clozapine, olanzapine and quetiapine exert benefits in terms of sexual functioning recovery due to their atypical mechanism of action. However, the potential adverse effect like metabolic syndrome should be adequately managed to prevent negative consequences. Psychosocial interventions, i.e. psychoeducation, destigmatization, supportive psychotherapy and psychiatric rehabilitation also play a crucial role in the management. In conclusion, restoration of sexual function is an achievable recovery target in patients with schizophrenia through these biopsycho- social interventions.
The Novelty of Bupropion As a Dopaminergic Antidepressant for the Treatment of Adult Attention Deficit Hyperactive Disorder

Deang KT, Sidi H, Zakaria H, Adam RL, Das S, Hatta NH, et al.

Curr Drug Targets, 2019;20(2):210-219.
PMID: 28494748 DOI: 10.2174/1389450118666170511145628

Attention deficit hyperactive disorder (ADHD), a hyperactivity disorder prevalent among children may continue as an adulthood attention deficit. To date, treating an individual with an adult ADHD may be an arduous task as it involves numerous challenges, which include a need for high index of suspicion to diagnose this medical condition. Many psychiatric disorders masquerade as ADHD and delay the necessary assessment and proper treatment for this debilitating medical disorder. Adult ADHD is often misdiagnosed (or under diagnosed) due to the fact that this medical condition is being masked by the patients' high level of intellectual achievement. As the ADHD in adult persists, it may end-up with impairment in the personal-social-occupational function in which the management becomes a great challenge. The treatment of ADHD can be optimized by using various drugs targets agents like norepinephrine-dopamine reuptake inhibitor (NDRI), with or without psycho stimulants like methylphenidate, which is marketed as Ritalin. Bupropion, an NDRI has a novel effect on ADHD as the molecule exerts its effects by modulating the reward-pleasure mesolimbic dopaminergic system and at the same time regulates the elevating mood dimension of the noradrenergic neurotransmission. The role of Bupropion in the neural and psychopharmacological perspective treatment of ADHD was deliberated. The present review highlights the novel effects of Bupropion in ADHD treatment, together with the help of other successful bio-psycho-social measures. This may be of immense benefit to the psychiatrists for treating their patients.
Loss of CXC-Chemokine Receptor 1 Expression in Chorioamnionitis Is Associated with Adverse Perinatal Outcomes

Wong YP, Wagiman N, Tan JW, Hanim BS, Rashidan MSH, Fong KM, et al.

Diagnostics (Basel), 2022 Apr 01;12(4).
PMID: 35453930 DOI: 10.3390/diagnostics12040882

Background: Chorioamnionitis complicates about 1−5% of deliveries at term and causes about one-third of stillbirths. CXC-chemokine receptor 1 (CXCR1) binds IL-8 with high affinity and regulates neutrophil recruitment. We aimed to determine the immunoexpression of CXCR1 in placentas with chorioamnionitis, and its association with adverse perinatal outcomes. Methods: A total of 101 cases of chorioamnionitis and 32 cases of non-chorioamnionitis were recruited over a period of 2 years. CXCR1 immunohistochemistry was performed, and its immunoexpression in placentas was evaluated. The adverse perinatal outcomes included intrauterine death, poor APGAR score, early neonatal death, and respiratory complications. Results: Seventeen cases (17/101, 16.8%) with chorioamnionitis presented as preterm deliveries. Lung complications were more common in mothers who were >35 years (p = 0.003) and with a higher stage in the foetal inflammatory response (p = 0.03). Notably, 24 cases (23.8%) of histological chorioamnionitis were not detected clinically. Interestingly, the loss of CXCR1 immunoexpression in the umbilical cord endothelial cells (UCECs) was significantly associated with foetal death (p = 0.009). Conclusion: The loss of CXCR1 expression in UCECs was significantly associated with an increased risk of adverse perinatal outcomes and could be used as a biomarker to predict adverse perinatal outcomes in chorioamnionitis. Further study is warranted to study the pathophysiology involved in the failure of CXCR1 expression in these cells.

Woon LSC, Zakaria H

East Asian Arch Psychiatry, 2019 Dec;29(4):118-123.
PMID: 31871308 DOI: 10.12809/eaap1851

OBJECTIVE: To determine the prevalence of adult attention deficit hyperactivity disorder (ADHD) and comorbid mental disorders in a Malaysian forensic mental hospital.
METHODS: All adult patients admitted to the forensic wards who were able to understand Malay or English language and give written informed consent were included. Participants were assessed using the Conners Adult Attention-Deficit Diagnostic Interview for DSM-IV (for presence of adult ADHD and a history of childhood ADHD) and the Mini International Neuropsychiatric Interview (for psychiatric comorbidities). Sociodemographic and offence-related data were also collected.
RESULTS: Of 199 patients admitted, 120 were included for analysis. The mean age of participants was 36.3 years. 94.2% were men. 81.7% were single, divorced, or separated. 25% had a history of childhood ADHD. The prevalence of adult ADHD was 15.8%. The persistence rate was 63%. Among the 19 participants with adult ADHD, the most common psychiatric comorbidities were substance dependence (68.4%), lifetime depression (63.2%), and generalised anxiety disorder (47.4%). Compared with participants without ADHD, participants with adult ADHD were less likely to be married (0% vs 21.8%, p = 0.022) and more likely to have alcohol abuse (15.8% vs 2%, p = 0.028), lifetime manic/hypomanic episodes (42.1% vs 7.9%, p = 0.001), and generalised anxiety disorder (47.4% vs 19.8%, p = 0.017), and were of younger age at first offence (21.8 years vs 26.9 years, p = 0.021).
CONCLUSIONS: Adult ADHD is common in a Malaysian forensic mental hospital and is associated with unmarried status, alcohol abuse, lifetime manic/hypomanic episodes, generalised anxiety disorder, and younger age at first offence.
Fulltext Effectiveness of a Malaysian Media Intervention Workshop: Safe Reporting on Suicide

Lim JTY, Cheng Q, Ng YP, Pheh KS, Panirselvam RR, Tay KW, et al.

Front Psychol, 2021;12:666027.
PMID: 34975604 DOI: 10.3389/fpsyg.2021.666027

Background: Suicide remains an important cause of premature deaths and draws much media attention. However, unsafe reporting and portrayal of suicides by the media have been associated with increased risk of suicidal behavior. Current evidence suggests that media capacity-building could potentially prevent suicide. However, there are still knowledge gaps in terms of a lack of data on effective strategies for improving awareness and safe reporting of suicide-related media content. This study aims to investigate the effectiveness of a workshop conducted with members of the media community on the safe reporting of suicide-related content. Methods: An interventional single-arm pre and post pilot study was conducted on a sample of the Malaysian media community recruited through purposive and snowball sampling. The media safe reporting workshop was conducted by a suicide prevention expert with a media industry background. Thirty participants completed a self-reported evaluation questionnaire on their awareness and knowledge of reporting on suicide-related media content; before and after the interventional workshop. Results: There was a significant difference between the total scores before and after the intervention, with a large effect size. Post-intervention scores were significantly improved in 8 items, namely those related to the reporting of: (i) the content of any suicide note; (ii) headlines with methods of suicide; (iii) headlines with the location of suicide; (iv) cases of suspected suicide despite the unconfirmed cause of death; (v) suicide news to cater to readers' interests; (vi) cause of suicide; (vii) details of the location of suicide; and (viii) the negative impact to media community when reporting suicide stories. In particular, there was an improvement in the majority of items for people from the media community with no lived experience of suicidal behavior. Conclusion: The media safe reporting workshop is a potentially effective intervention for improving awareness and knowledge measures relating to safe reporting on suicide among the media community, with a more pronounced effect in those without lived experience of suicidal behavior. Limitations in the sample size, generalizability, short-term evaluation, and lack of a control group warrant future larger, longer-term controlled, and more representative studies.
Fulltext Posttraumatic Growth and Coping Strategies Among Patients With Head and Neck Cancer: Do Approach Coping and Avoidant Coping Predict Posttraumatic Growth Over Time?

PMID: 34764904 DOI: 10.3389/fpsyg.2021.716674

Despite an enormous number of studies addressing the importance of posttraumatic growth (PTG) among cancer patients, the literature lacks data regarding how different coping strategies affect PTG among head and neck cancer (HNC) patients over time. This longitudinal study investigated the PTG trend and coping over 5-7months among a cohort of HNC patients within the first year after their diagnosis. It determined an association between coping strategies and PTG over time. The study's HNC respondents were administered a socio-demographic and clinical characteristics questionnaire during their baseline assessments. Additionally, the Malay versions of the "PTG Inventory-Short Form" (PTGI-SF) and the "Brief Coping Orientation to Problems Experienced Inventory" (Brief COPE) were administered during respondents' baseline assessments and follow-up assessments (5-7months after the baseline assessments). In total, 200 respondents reported an increasing PTG trend and approach coping (active coping, planning, positive reframing, acceptance, emotional support, and instrumental support) and a decreasing trend of avoidant coping (self-distraction and denial) over time. Two approach coping strategies (acceptance and planning) significantly increased PTG while denial was the only avoidant coping strategy that significantly lowered PTG, after controlling for socio-demographic and clinical characteristics, over time. Our study's findings identified the need to incorporate psychosocial interventions that enhance approach coping and reduce avoidant coping into HNC patients' treatment regimes.

Empowering Malaysian dentists to tobacco dependence treatment conduct

Nordin AS, Kadir RA, Yahya NA, Zakaria H, Rashid RA, Habil MH

Int Dent J, 2014 Aug;64(4):206-12.
PMID: 24835463 DOI: 10.1111/idj.12110

As a signatory to the World Health Organisation 2003 Framework Convention on Tobacco Control, Malaysia has policies in place and funded 300 public Quit clinics. Unfortunately, government dentists are not included to run tobacco dependence treatment. A cross-sectional exploratory survey was carried out to seek Malaysian dentists' opinion on their knowledge, perception and willingness to conduct tobacco dependence treatment. Participation was voluntary from those who attended a specially designed one-day, four-module workshop on tobacco cessation intervention. Data were collected using the Audience-Response-System equipment which tracked immediate responses covering four domains namely: smoking as a public health problem, smoking as an addiction, the role of dentists in the programme and confidence in conducting smoking cessation in the clinic. Sample comprised more female dentists (73.5%), mean age 33.6 (SD 8.99) years and with more than 3 years working experience. Findings indicated that the majority agreed Malaysia has a rising problem in the prevalence of smoking (71.6%) and predicted that it will affect mostly the young (81.9%). Only half of the dentists surveyed (58.9%) routinely recorded their patients' smoking habits. The majority (71.6%) believed that dentists are effective in helping their patient to stop smoking and 76.3% agreed that dentists should discuss the smoking habit with their patients; however, 60% agreed that doing so is too time consuming. In addition, only 24.7% knew of more ways to treat a smoking habit. The majority felt comfortable giving advice to patients about changing their habits (76.5%) or discussing treatment options (60.5%): 75% would opt for a combined programme of counselling and use of medication if they have to do, 15% would choose to go on counselling only, while 8% did not want to treat. In conclusion, the findings suggest that dentists have a strong potential to contribute significantly to providing smoking cessation treatment if adequately trained.
Fulltext Clinical and cognitive correlates of employment among patients with schizophrenia: a cross-sectional study in Malaysia

Midin M, Razali R, Zamzam R, Fernandez A, Hum LC, Shah SA, et al.

Int J Ment Health Syst, 2011 May 30;5:14.
PMID: 21624111 DOI: 10.1186/1752-4458-5-14

BACKGROUND: Gainful employment is one major area of functioning which is becoming an important goal in psychiatric rehabilitation of patients with schizophrenia. Studies in western countries are pointing to evidence that certain sociodemographic and clinical factors may contribute to employment outcomes in this group of people. However, the area is still largely unexplored in Malaysia. The aim of this study was to examine the sociodemographic, clinical and cognitive correlates of employment status among patients with Schizophrenia.
METHODS: This was a cross-sectional study. All participants who fulfilled the requirements of the study according to the inclusion and exclusion criteria were enrolled. Study instruments included a demographic data questionnaire, Positive and Negative Symptom Scale (PANSS), Trail Making Tests, Rey's Auditory Verbal Learning Test (RAVLT) and Digit Span. Bivariate analyses were done using chi-square for categorical data and t-test for continuous data and multiple logistic regression analysis was done to identify predictors of employment status.
RESULTS: A total of 95 participants who fulfilled the inclusion criteria were enrolled into the study. Among the sociodemographic, clinical and cognitive variables studied marital status, educational level, mean scores of negative symptoms, Digit Span and RAVLT and Trail Making Tests were found to show significant association with employment status on bivariate analyses. However, when entered into a logistic regression model, only cognitive variables ie. Trail A and B, Digit Span and RAVLT were significant predictors of employment status.
CONCLUSIONS: The results from this study support the role of cognitive function, particularly, attention, working memory and executive functioning on attaining and maintaining employment in persons with schizophrenia as measured by the RAVLT, Digit Span and Trail Making Tests. These findings may act as preliminary evidence suggesting the importance of integrating cognitive rehabilitation in the psychosocial rehabilitation program for patients with schizophrenia in Malaysia.
High-performance thin-layer chromatographic methods in the evaluation of the antioxidant and anti-hyperglycemic activity of Myrmecodia platytyrea as a promising opportunity in diabetes treatment

Agatonovic-Kustrin S, Morton DW, Adam A, Mizaton HH, Zakaria H

J Chromatogr A, 2017 Dec 29;1530:192-196.
PMID: 29132827 DOI: 10.1016/j.chroma.2017.11.012

The steady increase of diabetes is becoming a major burden on health care systems. As diabetic complications arise from oxidative stress, an antioxidant therapy along with anti-diabetic drugs is recommended. Myrmecodia or ant plant is highly valued as a traditional medicine in West Papua. It is used as an alternative treatment for diabetes, as the substances produced by ants can reduce blood sugar levels. The aim of this study was to develop and establish high-performance thin-layer chromatographic (HPTLC)-bioautographic methods to measure the antioxidant and hypoglycemic effects in different extracts from Myrmecodia platytyrea and to compare them with sterol content. Antioxidant activity in methanol, ethanol, dichloromethane (DCM) and ethyl acetate (EA) extracts were measured with a direct HPTLC-2,2-diphenyl-1-picrylhydrazyl free radical (DPPH) assay, while hypoglycemic effects were assessed using a newly developed α-amylase inhibitory activity assay. Stigmasterol is observed, after derivatization with anisaldehyde, as purple colored zones under visible light at hRF values of 0.66. The highest antioxidant activity was observed in the ethanol extract which is rich in polyphenols and flavonoids, while the DCM extract did not show antioxidant activity, but had significant α-amylase inhibitory activity. The highest α-amylase inhibitory activity was observed in the EA and DCM extracts and was related to their stigmasterol content.
Kernel elongation in rice

Golam F, Prodhan ZH

J Sci Food Agric, 2013 Feb;93(3):449-56.
PMID: 23238771 DOI: 10.1002/jsfa.5983

Kernel elongation after cooking is an important character of fine rice and most rice consumers prefer length-wise elongation. Although improvement of aromatic rice began early in the 1970s, until now the mechanisms and genetics of kernel elongation has remained unrevealed. Kernel elongation is considered as a physical phenomenon and is influenced by several physicochemical and genetic factors, including genotypes, aging temperature, aging time, water uptake, amylose content and gelatinization temperature. Recently the complete genetic map of fine rice has been created and the gene responsible for kernel length identified; moreover, this gene is tightly linked with the cooked kernel elongation trait. Several molecular markers linked with cooked kernel elongation have been developed. These tools will be helpful for the improvement of this important trait. For the proper study of cooked kernel elongation of rice, this review paper will provide the basis and directional materials for further studies.

MyJurnal

Exhibitionism is a distressing condition which may have a link with the increasing availability and usage of online sexual activities (OSA). We highlight a 42-year-old man who presented with a constant craving for OSA to achieve his sexual satisfaction which included exposing his genitalia to virtual partners, unsuspected strangers, and colleagues in public areas. His sexual behaviours were further reinforced by an online video chatting with genitalia exposure, which ended commonly with an exchange of masturbatory acts. He denied any problem with his erection and able to achieve orgasm via common sexual acts. There was no past psychiatric history nor family history of mental disorder. He volunteered to seek psychiatric help and subsequently given a psycho education on his illness and how to cope with the distress associated with his sexual acts. He was scheduled for an intensive psychotherapy to instil insight and hope to deal with his sexual difficulties.
Fulltext Zerumbone Ameliorates Neuropathic Pain Symptoms via Cannabinoid and PPAR Receptors Using In Vivo and In Silico Models

Chia JSM, Farouk AAO, Mohamad TAST, Sulaiman MR, Zakaria H, Hassan NI, et al.

PMID: 34202590 DOI: 10.3390/molecules26133849

Neuropathic pain is a chronic pain condition persisting past the presence of any noxious stimulus or inflammation. Zerumbone, of the Zingiber zerumbet ginger plant, has exhibited anti-allodynic and antihyperalgesic effects in a neuropathic pain animal model, amongst other pharmacological properties. This study was conducted to further elucidate the mechanisms underlying zerumbone's antineuropathic actions. Research on therapeutic agents involving cannabinoid (CB) and peroxisome proliferator-activated receptors (PPARs) is rising. These receptor systems have shown importance in causing a synergistic effect in suppressing nociceptive processing. Behavioural responses were assessed using the von Frey filament test (mechanical allodynia) and Hargreaves plantar test (thermal hyperalgesia), in chronic constriction injury (CCI) neuropathic pain mice. Antagonists SR141716 (CB1 receptor), SR144528 (CB2 receptor), GW6471 (PPARα receptor) and GW9662 (PPARγ receptor) were pre-administered before the zerumbone treatment. Our findings indicated the involvement of CB1, PPARα and PPARγ in zerumbone's action against mechanical allodynia, whereas only CB1 and PPARα were involved against thermal hyperalgesia. Molecular docking studies also suggest that zerumbone has a comparable and favourable binding affinity against the respective agonist on the CB and PPAR receptors studied. This finding will contribute to advance our knowledge on zerumbone and its significance in treating neuropathic pain.
Quantification and characterisation of Trichoderma spp. from different ecosystems

Sariah M, Choo CW, Zakaria H, Norihan MS

Mycopathologia, 2005 Jan;159(1):113-7.
PMID: 15750742

Basal stem rot of oil palm caused by Ganoderma boninense is of major economic importance. Observations of the low incidence of disease due to Ganoderma species in natural stands, suggest that the disease is kept under control by some biological means. Trichoderma spp. are saprophytic fungi with high antagonistic activities against soil-borne pathogens. However, their abundance and distribution are soil and crop specific. Trichoderma species have been found to be concentrated in the A1 (0-30 cm) and Be soil horizons (30-60 cm), although the abundance of Trichoderma was not significantly different between the oil palm and non-oil palm ecosystems. Characterisation of Trichoderma isolates based on cultural, morphological and DNA polymorphism showed that T. harzianum, T. virens, T. koningii and T. longibrachiatum made up 72, 14, 10 and 4% of the total Trichoderma isolates isolated. As Trichoderma species are present in the oil palm ecosystem, but at lower numbers and in locations different from those desired, soil augmentation with antagonistic Trichoderma spp. can be developed as a strategy towards integrated management of basal stem rot of oil palm.
