Hamoud HA

International Medical Journal Malaysia, 2014;13(2):29-33.
MyJurnal

Introduction: Presently, the use of Eurycoma longifolia Jack (ELJ) (Tongkat Ali) has increased dramatically in Southeast Asia especially Malaysia where it is widely used as aphrodisiac and anti-malarial agent. Interestingly, its consumption has become popular in daily life as beverage to enhance energy and stamina especially among males. However, its effect on the safety of vital organs of the body has not been studied adequately. Hence, the main objective of this study was to determine whether or not long-term use of ELJ any has side effects on the liver in rats.

Methods: Three different concentrations of aqueous extract of ELJ were prepared and dissolved in distilled water. A total of 32 Sprague-Dawley male rats were used and randomly divided into three test groups and control. The test groups were given different doses (low dose 250 mg/kg bw, medium dose 500mg/kg bw and high dose 1000 mg/kg bw) of aqueous extract of ELJ, respectively. Control group was given distilled water alone. Doses were given orally and daily for 5 weeks. After 5 weeks, animals were sacrificed; whole liver tissues were obtained, fixed in 10 percent formaldehyde overnight for histological examination.

Result: Histological observations showed mild to moderate degrees of hemorrhage, hepatocytes degeneration and severe fatty changes in liver tissue of the test groups treated with ELJ as compared to control.

Conclusion: In conclusion, the long-term daily consumption of ELJ in large quantity as beverage may cause fatty changes, hemorrhage and hepatocytes degeneration in the liver tissue.

Xiang Sha Yang Wei Wan (XSYWW) is a Chinese traditional medicine that is used for gastrointestinal disorders, specifically gastric ulcer in many countries of South-East Asia. The aim of the study was to evaluate the potential effects of XSYWW on ethanol-induced gastric ulcer in rats by means of histological Study. On a similar basis of treatment, ranitidine, a conventional medication was used as gold standard. Methods: Fifty five male Sprague-Dawley rats (250-300 gm) were divided into four groups. Group I (ethanol treated group) was the control group and gastric ulcers were induced by administering 100% ethanol (1 ml/200 g). Group II (Pre-treatment group) was divided into two subgroups; they were orally fed with 1.0 gm/kg and 2.0 gm/kg respectively of XSYWW solution. Thirty minutes later they were administered with absolute ethanol as in group I. Group III, was given an oral dose of 2gm/kg of XSYWW solution after one hour of ethanol administration. Group IV was given an oral dose of 200mg/kg ranitidine solution after one hour of ethanol administration. Five rats from groups I, III and IV were sacrificed on day 1, 2 and 3 while the animals of group II were sacrificed one hour after ethanol administration. Results: Histological study of the stomachs from ethanol treated rats showed multiple ulcers of various depths that reached the muscularis and the serosa. Conclusion: Pre or post-treated rats with XSYWW showed that XSYWW has protective effect against ethanol-induced gastric mucosal lesion. However, there was a faster and more complete healing process in the ranitidine treated group when compared to the XSYWW treated subjects.

This study assessed the effect of calcium supplementation towards the change in serum calcium,
phosphorus and magnesium level. We carried out a randomized controlled trial of calcium supplementation in 113 postmenopausal women for 24 months period study. Subjects were randomly assigned into two groups. Subjects in Calcium Supplemented Group (CSG) were to take calcium supplement (1200 mg/day) while the Control Group were not given any placebo and advised to continue with their regular diet. The study showed that calcium supplementation helps to increased daily intake of calcium amongst the subject which in results helping to maintain the serum calcium level within normal range. The serum magnesium and phosphorus level in this study were kept at a normal range although there is a slight decrease in serum phosphorus levels may be due to a reduction in the daily intake of the mineral.

The objective of this study was to determine the physicochemical properties of pink guava (Psidium guajava) puree and its anti-hypertensive effect on Spontaneous Hypertensive Rats (SHR). Antioxidant activities of pink guava puree in water and ethanol extracts, based on 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, were 1.43±0.04 mg/gfm and 0.28±0.01 mg/gfm, respectively. A total of 24 male SHRs were divided into a control group, CG, and 3 treatment dosage groups [low dose group, LDG (0.5 g/kg body weight/day), medium dose group, MDG (1.0 g/kg body weight/day), and high dose group, HDG (2.0 g/kg body weight/day)]. Final body weights for treatment dosage groups were lower [MDG (313.01±31.25 g), HDG (318.56±17.96 g), LDG (320.01±22.70 g)] compared to CG (331.08±41.29 g). Final systolic blood pressure values from the beginning and the end of the experiment in MDG and HDG were 231-179 mmHg and 246-169mm Hg, respectively. These results were significantly lower when compared with CG (241-223 mmHg) from the beginning until the end of the experiment. As a conclusion, these results showed that pink guava puree has anti-hypertensive properties.

Eur J Dent, 2017 4 25;11(1):76-82.
PMID: 28435370 DOI: 10.4103/ejd.ejd_238_16

OBJECTIVES: The aim of this study was to evaluate the vertical and sagittal facial profile and maxillary arch width, depth, and length of patients with unilateral cleft lip and palate (UCLP) and to compare them with healthy noncleft children in the mixed dentition stage (7-13 years).
MATERIALS AND METHODS: This study is conducted at Hospital Universiti Sains Malaysia. UCLP group comprised 48 patients with nonsyndromic UCLP who have had the lip and palate repaired, whereas the control group comprised 48 healthy noncleft cases. The lateral cephalometrics measurements were used to determine the vertical height, sagittal depth of the face, and cranial base length and angle. Maxillary arch dimensions were measured on the study cast including arch width, depth, and length.
RESULTS: Vertical facial height and sagittal depth measurements showed a significant decrease (P < 0.05) in the mean growth pattern in UCLP group. The anterior cranial base length (S-N) was shorter in UCLP children (P < 0.001), while Ba-N length had no significant difference (P = 0.639). Nasion-Sella Tursica-Basion angle was significantly higher in the UCLP group (P = 0.016). Dental arch width with reference to canine-to-canine and first premolar-to- first premolar distance was significantly larger in control (P = 0.001).
CONCLUSION: Mean vertical and sagittal facial dimensions in the UCLP children who do not undergo orthodontic treatment are significantly lesser in all directions of growth than healthy noncleft children. The maxillary dental arch had a normal depth but constricted in width and arch length.

The accumulation of tear film proteins as well as microbes colonization onto worn contact lenses can be eliminated conventionally by mechanical rubbing during the cleaning process. Lens2® functions in rotation manner to loosen the deposits on the contact lens and has antimicrobial coating to keep lenses away from contamination. The objective of this study was to determine the efficiency of Lens2® to remove deposited protein and reduce microbial contamination compared to conventional method. Twenty-eight subjects each wore a pair of contact lens FDA Group 1 (Polymacon, SoftLens® 38, Bausch & Lomb) for one month and cleaned them using multipurpose solution (COMPLETE® MoisturePLUSTM, Advanced Medical Optics) separately using two different methods. The right lens was cleaned conventionally while the left lens were cleaned using the Lens2®. The control group of thirteen subjects each wore a pair of contact lens for the same period and cleaned both conventionally. These lenses and its cases were then analyzed for protein deposition using Bichinchoninic Acid Assay (BCA) Kit (Sigma, USA) in 96-well plate. Microbial contamination was determined by culturing the samples on nutrient agar for bacteria and fungi and non-nutrient agar for amoeba isolation. The mean of total protein on control lenses (17.014 ± 13.246 µg/mL) was not significantly different from those on the Lens2® (21.623 ± 19.127 µg/mL). There were also low growth numbers of amoeba in each group of samples. Interestingly, there were no growths of amoeba from all Lens2® samples collected. There was also low growth numbers of bacteria in each sample group whereby Lens2® had the lowest growth of bacteria. No growth of fungi was obtained from all samples. The automatic lens cleaner, Lens2® was found to be as efficient as the conventional cleaning method. However, the Lens2® has additional advantage because of its antimicrobial material and need shorter time in the cleaning process as well as easy and effective.

Thyroxine has been shown to have a beneficial effect on renal function in cases of impending renal failure in ani-mal studies.'5 Studies of the use of thyroxine in humans in impending renal failure are scarce. The aim of this study was to assess the effect of oral thyroxine on the renal function of asphyxiated term neonates who often have renal impairment.
A randomised control trial was conducted, involving 30 term asphyxiated neonates. The study group (n=15) was given thyroxine (50 pg) orally on days 1, 2 and 3 of life and placebo was given to the control group (n=15). Renal function was studied on day 1 and day 4 of life. The two groups did not differ significantly as regards gestational age, birth weight, severity of asphyxia, preg-nancy or delivery complications, fluids administered and drugs used. There was no significant difference in urine output, creatinine clearance and fractional excretion of sodium on day 1 but there was a trend towards a worse renal function on day 1 in the treatment group. The creatinine clearance was significantly better in the treat-ment group on day 4 (p = 0.017). Urine output and fractional excretion of sodium on day 4 were better in the treatment group but the differences did not reach statistical significance (p = 0.14 and 0.057 respectively). Statistical analysis on the differences between day 4 and day 1 showed statistical significance only for creatinine clearance: creatinine clearance day 4 minus creatinine clearance day 1 was 52.6 (±32.4) for the thyroxine group and 7.3 (±7.8) for the controls (p= 0.006).
These data support the hypothesis that thyroxine may have a significant beneficial effect on the renal function in term neonates with perinatal asphyxia. Thyroxine may be proven useful in future for patients with impending renal failure.

MyJurnal

Many researchers have emphasized the importance of teaching stress management and self-care skills to medical students as they are vulnerable to develop psychological health problems. The researchers designed a 4-hour intervention based on the DEAL model to address these problems. This study aimed to determine outcomes of the DEAL-based intervention on medical students’ stress, anxiety and depression symptoms. Methods: A randomized controlled trial study was conducted on 171 medical students. Their stress, anxiety and depression symptoms were measured by the 21-item Depression Anxiety Stress Scale at five intervals; at 2 weeks before the intervention, and at 1 week, 8 weeks, 16 weeks and 32 weeks after the intervention. The mixed model ANCOVA was applied to determine the effect of the intervention on the participants’ psychological health at five intervals. Results: A total of 153 medical students (intervention = 73 and control = 80) completed this study. Results showed that the intervention group experienced significantly lower stress and depression symptoms than the control group. Although anxiety scores are consistently lower in the intervention group, no significant differences between groups were found. Conclusion: These results support the favourable outcomes of the intervention on psychological health of medical students. It is a promising intervention to be considered by medical schools as it consumes minimal amount of time, money, training and man power as well can be implemented easily.

The aim of this study was to evaluate the effects of a DVDdelivered mindfulness-based intervention for reducing stress among medical students in a Malaysian university. Methods: A total of 76 medical students participated in the intervention program (Mindful-Gym DVD). They were stratified according to year of studies and randomly allocated to intervention (N = 38) and control groups (N = 38). The following outcome variables were measured at pre- and post-intervention: mindfulness (with Mindful Attention Awareness Scale, MAAS); perceived stress (with Perceived Stress Scale, PSS); mental distress (with Depression, Anxiety and Stress Scale, DASS); and self-efficacy (with General Selfefficacy Scale, GSE). Hierarchical multiple regression analyses were used to analyse the effect of group (Intervention vs. Control) on changes in the outcome variables. Results: One week after the intervention, participants in the intervention group reported significantly greater improvements with small to medium effect sizes in self-reported levels of mindfulness (β =0.19, ∆R2= 0.04, p = 0.028, f2= 0.07), perceived stress (β = -0.25, ∆R2=0.06, p = 0.006, f2= 0.11), mental distress (β = -0.27, ∆R2= 0.07, p =0.003, f2= 0.13), and self-efficacy (β = 0.27, ∆R2= 0.07, p = 0.003, f2= 0.13), compared to participants in the control group. The number needed to treat (NNT) to achieve ‘normal’ levels of depressive, anxiety, and stress symptoms (as indicated by the DASS scores) were 5, 8, and 6 respectively. Conclusions: This study found that the DVD-delivered mindfulness-based program is potentially a labour- and cost-effective and easily accessible stress reduction program for medical students.

The aim of this study was to investigate the acute (one-day treatment) effect of a methanol extract of
Orthosiphon stamineus, Benth on glutathione-S-transferase (GST) activity in streptozotocin (STZ)-induced diabetic young male and female Sprague Dawley (SD) rats. The methanol extract of O. stamineus was administered orally (5, 31.25, 125 and 500 mg/kg) to diabetic rats, and the effect on GST activity was measured by the method of Habig et al. (1974). No lethality and no significant changes in body weight and water intake were observed in the treated group as compared to the control group. A significant increase in the activity of GST was observed in the liver S-9 cytosolic fraction of diabetic male SD rats treated with 125 mg/kg (P < 0.01) and 500 mg/kg (P < 0.01) of the methanol extract O. stamineus. Administration of 500 mg/kg (P < 0.01) of the methanol extract of O. stamineus to diabetic female SD rats increased GST activity when compared to the control group. This study indicates that the methanol extract of O. stamineus could affect the activity of GST in rat liver and the effect seen was dose-dependent.

MyJurnal

Introduction: The study was conducted to look for the effects of polycythaemia on Glycosylated Haemoglobin (GHb) levels and to the see the correlations between the levels of haemoglobin, GHb, blood glucose, and lipid proﬁ les including Atherogenic Index of plasma (AIP), in type 2 diabetics living 5800ft above sea level at Gangtok in Sikkim, India. GHb is used to predict the risk of long term complications of Diabetes mellitus (DM) like coronary artery disease (CAD). Materials and Methods: The study group consisted of Group I (Type 2 DM male patients with PPG levels 200mg/dl) and age matched healthy males formed the control group. Results: In Group I, GHb levels correlated positively with AIP, but not with TC/HDL-C ratio. In Group II, both PPG and GHb levels correlated positively with Total cholesterol (TC), LDL Cholesterol, TC /HDL-C ratio and AIP. This shows that higher PPG levels are associated with more Atherogenic lipid proﬁ les. Study also showed higher GHb levels in controls at 7.61%, and correlated positively with postprandial glucose (PPG) levels (r = 0.92). Conclusion: In predicting risk for future CAD, PPG levels and AIP can be used as an adjunct parameter.

Objective: Anxiety and depressive symptoms are common among cancer patients and have been shown to adversely affect their health-related quality of life (HRQoL). Dark chocolate is popular for its beneficial effects on mood regulations. This study aimed to assess the effects of dark chocolate consumption on anxiety and depressive symptoms and the HRQoL status
among cancer patients. Methods: A sample of 133 cancer patients was recruited from 3 public hospitals in the East Coast Peninsular of Malaysia. The anxiety and depressive symptoms was assessed by the Malay Hospital Anxiety and Depression Scale (HADS) while HRQoL was measured via the Malay McGill Quality of Life questionnaire (MMQoL). Patients were randomly assigned to Study Group (SG) and Control Group (CG) whereby dark chocolate (50g) was administered to SG while CG consumed mineral water for 3 consecutive days. Results: Specifically, the anxiety and depressive symptoms was significantly reduced after dark chocolate consumption. The HRQoL score was also significantly increased in SG at post-intervention. Conclusion: These findings indicated that a 3-day dark chocolate consumption may reduce anxiety, depressive symptoms and thus also improved the HRQoL status in hospitalised cancer patients.

The aim of this study was to assess the wear of tungsten carbide burs and round rotary diamond instruments through measurements of rake angle and visual observations respectively under a field emission scanning electron microscope. Sixty short and long head pear-shaped tungsten carbide burs and 18 round rotary diamond instruments that had been used to complete < 5, > 5 and > 10 cavity preparations (n=10/group) were selected from the 3rd and 4th year dental students, Faculty of Dentistry, University of Malaya. There were two control groups consisting of long and short tungsten carbide burs of ten each. Two-way ANOVA was used to analyse the rake angle data. The data from the two control groups were collectively analysed following multiple paired t-test (p>.05) which showed no significant difference between the two types of tungsten carbide bur (short and long head). The mean rake angle of the control group was significantly higher (p < .05) compared to the < 5, > 5 and > 10 cavity preparation groups. The rake angle of the > 10 cavity preparation group was significantly lower than the other two test groups (p < .05). Round rotary diamond instruments in the < 5 cavity preparation group showed intact diamond particles with distinct cutting facets comparable to the control group. However, diamonds instruments in the > 5 and > 10 cavity preparation groups showed blunt diamond particles. In conclusion, wear of tungsten carbide burs and round rotary diamond instruments were evident after repeated use. Wear was more pronounced when instruments were used to prepare more than ten cavities.

The health related quality of life (HRQoL) of chronic obstructive pulmonary disease (COPD) patients is greatly influenced by their health status. The Health Index Questionnaire - Short Form 36 (SF-36) and St George Respiratory Questionnaire (SGRQ) are commonly used to assess the HRQoL of COPD patients. Objective: This study investigates differences in HRQoL following sessions of pulmonary rehabilitation program (PRP) with a control group (CG) that had no intervention. Method: This quasi-experimental study involving 17 subjects assigned to the CG and 16 subjects in the intervention group (IG). Ethical approval was obtained from the relevant authority. Both groups were given the health index questionnaires- SF-36 and SGRQ prior and 5 weeks after the intervention. The CG only had medication while the IG performed exercises (cycling, treadmill walking, upper limb strengthening exercise and stair climbing exercise). Results: Data analysis using SPANOVA demonstrated significant improvement in HRQoL measured from SF-36 in domains of bodily pain (p=0.005), vitality (p=0.021) and mental health (p=0.002) in IG unlike the CG. Similarly, SGRQ, also shows improvement in symptom (p=0.028), activity (p=0.004) and total score (p=0.012. Conclusion: The 5 weeks pulmonary rehabilitation program demonstrated improvement in HRQoL among COPD
patients.

Journal of Occupational Safety and Health, 2004;1(1):31-37.
MyJurnal

This retrospective study was conducted at the audiology clinic of UKM in the year 2000. It was intended to detect the effect of walkman on the hearing system of its users and to investigate whether distortion product otoacoustic emission test can provide an early and reliable sign of cochlear damage or not. Distortion product otoacoustic emission test helps to determine the function of outer hair cell. Outer hair cells get damaged with exposure to loud sound, drugs and aging. Thirty subjects (20 in the study group and 10 in the control group), between the ages of 19-25 years, who fulfilled all the criteria of selection, were investigated. There were two sets of criteria (general and specific). Anyone, in the control or study group, failing in any of these criteria was excluded from the study. According to the general criteria, it was essential for all the subjects to have clean ear canals, normal hearing at all the frequencies (250Hz- 8000Hz), normal middle ear function (Type A tympanogram), no middle ear problem, not used/using any ototoxic medicine, no family history of hearing loss, no history of ear surgery, not exposed to any form of loud noise like disco, concert, F1 racing or gun shooting. According to the special criteria it was essential for the subjects in the control group to have never used a walkman and those in the study group must have been using a walkman for at least 6 months. Comparison of distortion product emission levels between control and study groups revealed that emissions were significantly lower in the study group, across all the frequencies, suggesting outer hair cell damage in the walkman users. These differences reached level of statistical significance (p<0.05) at 2, 4, 6 and 8kHz. Using walkman at an intensity unsafe for hearing and a duration longer than recommended is suspected for the outer hair cell damage in our study group. Those using walkman for longer duration and higher intensity manifested much lower emission levels. Our study supports the literature that distortion product emission test is a much sensitive test than pure-tone audiometry, as it can detect cochlear damage long before it appears in an audiogram. It is recommended that people who are exposed to loud noise regularly should be monitored with distortion product emission test. It is suggested that the use of walkman.

Palm tocotrienol is a potent antioxidant and has the poten-tial to be used for treatment of post-menopausal osteoporosis. The aim of the study is to determine if palm tocotrienol supplementation could alleviate oxidative stress in ovariectomised rat model and improve its bone strength. The rats were di- vided into four groups: (i) sham-operated group (SHAM) (ii) ovariectomised-control group (OVX) (iii) ovariectomised and given 60mg/kg α-tocopherol by oral gavage (OVX + ATF) (iv) ovariectomised and given 60mg/kg palm tocotrienols by oral gavage (OVX + PTT). After eight weeks of treatment, blood samples were taken to measure oxida-tive status (MDA, SOD and GPX) while the femurs were biomechanically tested for strength and resistance to fracture. Ovariectomy was shown to induce oxidative stress as shown by the raised MDA levels and reduced GPX activity. Palm tocotrienols seemed to offer protection against the ovariectomy-induced oxidative stress as shown by the suppression of MDA levels and raised GPX and SOD activities in the OVX+PTT group. In comparison, α-tocopherol was only able to raise the SOD but not as high as palm tocotrienols. The biomechanical tests have shown that ovariectomy has not af-fected the bone strength significantly after eight weeks. Palm tocotrienols supplemen-tation for eight weeks was effective in preventing oxidative stress in a post-meno-pausal rat.
