Accidental poisoning in children is a preventable condition. It is a problem mainly in children aged 1 to 4 years. This is a descriptive study of accidental poisoning in children below 12 years old admitted to Hospital Seremban from October 15, 1994 to October 14, 1995. A major cause of household accidental poisoning was kerosene ingestion (25%) followed by ingestion of medications (22%), liniment methyl salicylate (12 %), mothballs (12%) and hypochlorinate solution (9%). There was a higher incidence of poisoning in males (50.8%), among Indians (41.2%) and in children from lower social classes (67%). A greater proportion of the accident occurred when the child was taken care by the parents (53 %) and in the house (80%). Most of the poison was ingested from its original package (81%). The immediate action taken was sending the child to the hospital (75%) without carrying out other actions such as washing the child’s mouth. The delay of sending the child to hospital was due to husband not at home (57%). Most of the cases (72.1 %) were discharged well within 1-2 days following admission.

Muscle-relaxant activity in Asian Strychnos species. A re-examination of two western Malaysian dart poisons

Bisset NG, Baser KH, Phillipson JD, Bohlin L, Sandberg F

Lloydia, 1977 Nov-Dec;40(6):546-60.

PMID: 600024

Two supposedly Strychnos-based Semai Senoi dart poisons from Western Malaysia, ipoh akar and lampong, and their accompanying plant materials have been re-investigated botanically, chemically, and pharmacologically. The two poisons contained tertiary and quaternary alkaloids, including strychnine and bis-quaternary dimeric bases, and also cardiotonic glycosides. The dominant pharmacological activity of the highly toxic ipoh akar poison was convulsant. The weaker lampong poison had muscle-relaxant activity of the curarizing type. The alkaloids of the two poisons were almost certainly derived from Strychnosignatii Berg. (S. ovalifolia Wall. ex G. Don) and not from S. vanprukii Craib to which the accompanying plant materials probably belong, while the cardiotonic glycosides of the two poisons came from Antiaris toxicaria Lesch. The quaternary alkaloids of both S. ignatii and S. vanprukii have muscle relaxant activity.

A confirmed bite by a Beautiful Pit Viper (Trimeresurus venustus) resulting in local symptoms

Fuchs J, Bessire K, Weiler S

Toxicon, 2019 Mar 20;163:44-47.

PMID: 30902684 DOI: 10.1016/j.toxicon.2019.03.019

This case report describes the effect of an envenomation by the Beautiful Pit Viper Trimeresurus venustus (or Cryptelytrops venustus), which is a green pit viper native to Thailand and Malaysia. A previously healthy 60-year-old snake breeder with no relevant medical history was bitten by his adult T. venustus in the third finger of his right hand while taking it out of the feeding box. The bite was painful and swelling progressed to include his whole hand within an hour after the bite. He was treated symptomatically with pre-emptive antibiotics and analgesics, never developed any hematological disorders such as coagulopathy and bleeding or disseminated intravascular coagulation and was discharged 26 hours after the bite. The clinical course in our patient matched two other well-documented cases reported to our Poisons Centre, and one further case presented as a conference-poster. All patients recovered with symptomatic therapy and never required antivenom. Therefore, bites by T. venustus seem to present with less severe symptoms compared to other Trimeresurus species.

Nickel and zinc complexes of testosterone N4-substituted thiosemicarbazone: Selective cytotoxicity towards human colorectal carcinoma cell line HCT 116 and their cell death mechanisms

Heng MP, Sim KS, Tan KW

J Inorg Biochem, 2020 07;208:111097.

PMID: 32438269 DOI: 10.1016/j.jinorgbio.2020.111097

Two new Schiff base ligands (TE and TF) were prepared from conjugation of testosterone with 4-(4-ethylphenyl)-3-thiosemicarbazide and 4-(4-fluorophenyl)-3-thiosemicarbazide, respectively. Their nickel (NE and NF) and zinc (ZE and ZF) complexes were reported. X-ray crystallography revealed a distorted square planar geometry was adopted by NE. The compounds demonstrated excellent selectivity towards the colorectal carcinoma cell line HCT 116 despite their weak preferences towards the prostate cancer cell lines (PC-3 and LNCaP). Against HCT 116, all these compounds were able to arrest cell cycle at G0/G1 phase and induce apoptosis via mitochondria-dependent (TE, NE, and TF) and extrinsic apoptotic pathway (ZE, NF, and ZF). Moreover, only ZE was able to act as topoisomease I poison and halt its enzymatic reactions although all compounds presented excellent affinity towards DNA.

The nutritional value of indigenous fruits and vegetables in Sarawak

Hoe VB, Siong KH

Asia Pac J Clin Nutr, 1999 Mar;8(1):24-31.

PMID: 24393732

The proximate composition including mineral and vitamin contents of 16 fruits and 46 vegetables (leaves, fruits, palm hearts and shoots) of indigenous origin in Sarawak are provided. Fruits like dabai (Canarium odontophyllum), kembayau (Dacryodes rostrata f. cuspidata), durian nyekak (Durio kutejensis) and durian kuning (Durio graveolens) are very nutritious with high values for energy, protein and potassium. Among the vegetables, the protein content of letup (Passiflora foetida), kepayang (Pangium edule) and tubu (Pycnarrhena tumetacta) is high, ranging from 6 to 7%. The range of nutrients among foods of indigenous origin are generally comparable with those of many cultivated species except for vitamin C, which is lower. Teh Kampung (Leucosyke capitellata) leaves are particularly high in magnesium (626 mg/100 g). Some of the indigenous vegetables contain antinutritional factors. Kepayang has very high levels of hydrogen cyanide (1834 µg/g on dry basis) but this poison can be completely evaporated by boiling. Indigenous fruits and vegetables which are pesticide residue free are important food sources for rural populations. Nutritious indigenous fruits and vegetables have the potential to be promoted for wider use, domestication and commercialization.

Fulltext Usage of traditional medicines among elderly and the prevalence of prednisolone contamination

Ismail Z, Mohamed R, Mohd Hassan MH, Wan Su K

Malays J Med Sci, 2005 Jul;12(2):50-5.

PMID: 22605958

The elderly consume many medications including traditional medicines. In 1986, it was found that 29% of elderly took traditional medicines although in 1996, the National Health Morbidity survey reported a 2.3% prevalence. However, studies from other countries showed much higher percentages. The Ministry of Health in Malaysia is concerned that some of these preparations maybe contaminated with steroids, antihistamines, hormones and other poisons. The aims of the study were to determine a). the health seeking behaviour of elderly Malays living in rural areas, b). the utilization of both modern and traditional medicines and c). the steroid content of the traditional medicines used. Methodology included interviews using structured questionnaires of elderly Malays living in rural areas of Kelantan, aged above 60 years. Samples of traditional medications collected were sent to the Pharmacology Department, School of Medical Sciences, Universiti Sains Malaysia, for steroid content analysis using Thin Layer Chromatography. A total of 599 elderly respondents were interviewed comprising 62.4% females and 37.6% males. The 60-69 years cohort group made up 48.7%, followed by 70-79 years at 36.1% and the remainder 15.2% were more than 80 years. There were 82% of elderly taking medicines. The trends of utilization of modern and traditional medicine in the last two weeks among elderly were 59.3% and 40.9% respectively. The utilization of traditional medicine by rural elderly Malays was therefore much higher than that reported in the previous study and nearly similar to that of France and Australian studies. There were 102 samples of traditional medications collected and analysed for steroid content. Results showed that 27.5% were positive for prednisolone, 34.3% positive for unknown steroids (a total of 61.8%) and 38.2% were negative for both steroids. The present study therefore once again confirmed the high usage of traditional medicines where some of which are contaminated with steroids.

Fulltext Epidemiology and risk factors of pesticide poisoning in Malaysia: a retrospective analysis by the National Poison Centre (NPC) from 2006 to 2015

Kamaruzaman NA, Leong YH, Jaafar MH, Mohamed Khan HR, Abdul Rani NA, Razali MF, et al.

BMJ Open, 2020 06 01;10(6):e036048.

PMID: 32487578 DOI: 10.1136/bmjopen-2019-036048

OBJECTIVE: Pesticide poisoning is a global health problem, and its progressive deterioration is a major cause of concern. The objective of this study is to assess epidemiological characteristics and identify risk factors of pesticide poisoning in Malaysia.

SETTING: Pesticide poisoning database of Malaysia National Poison Centre (NPC) from 2006 to 2015.

PARTICIPANTS: Telephone enquiries regarding pesticide poisoning were made by healthcare professionals. Information received by the NPC was entered into a retrievable database of standardised Poison Case Report Form, as adapted from the World Health Organization (WHO).

OUTCOMES: The outcome of the study is to provide an overview of national epidemiological profile of pesticide poisoning. High-risk groups of people and their circumstances were also identified to ensure that appropriate measures are strategised.

RESULTS: Within the study period, a total of 11 087 pesticide poisoning cases were recorded. Sixty per cent of these cases were intentional in nature and most were found among male individuals (57%) of the Indian race (36.4%) aged between 20 and 29 years (25.5%), which occurred at home (90%) through the route of ingestion (94%). The highest number of poisoning was due to herbicides (44%) followed by agricultural insecticides (34%), rodenticides (9.9%), household insecticides (9.5%) and fungicides (0.5%). In addition, 93.6% of intentional pesticide poisoning cases were caused by suicide attempts. The results of this study show that there was an increasing trend in pesticide poisoning incidents over the 10-year duration. This indicates that pesticide poisoning is a prevalent public health problem in Malaysia, resulting in an average incidence rate of 3.8 per 100 000 population.

CONCLUSIONS: Deliberate pesticide ingestion as a method of suicide has become a disturbing trend among Malaysians. Therefore, regulation of highly hazardous pesticides must be enforced to ensure controlled and limited access to these chemicals by the public.

Fulltext Use of intramuscular botulinum toxin in Malaysian children with cerebral palsy

Khoo TB, Yusniza MY, Chern PM

Med J Malaysia, 2007 Mar;62(1):3-5.

PMID: 17682560 MyJurnal

A study was carried out to determine the clinical effectiveness of intramuscular botulinum toxin type A (BTX) in the treatment of spasticity or dystonia in 58 consecutive children with cerebral palsy (CP). The effectiveness of the treatment was determined by the reduction of spasticity and global parental perception scale. The mean age of treatment was six years and the most frequent aim of treatment (91.1%) was functional improvement. The median reduction of spasticity as measured by modified Ashworth scale was 1. The short term outcome was graded as excellent or good by 44.6% and satisfactory by 38.4% of parents. Patients with dyskinetic Cerebral Palsy had the best response. Adverse effects were minimal. BTX treatment is modestly effective in the majority of our patients with spastic and dyskinetic cerebral palsy.

Analysis of some Malaysian dart poisons

Kopp B, Bauer WP, Bernkop-Schnürch A

J Ethnopharmacol, 1992 Feb;36(1):57-62.

PMID: 1501494

An investigation of nine Malaysian dart poisons has confirmed that their main active components are cardenolides from Antiaris toxicaria (Pers.) Lesch. and alkaloids probably from different forms of Strychnos ignatii P. Bergius. It is not possible to determine the ethnic origin of the poisons from the results of the analyses on their own. Two new cardiac glycosides have been isolated and their structures determined as 12 beta-hydroxycannogenin 3 beta-O-beta-D-deoxygulopyranoside and 3 beta-O-alpha-L-rhamnopyranoside, respectively.

MyJurnal

Naturally, plant habitats are exposed to several potential effects of biotic and different abiotic environmental challenges. Several types of micro-organisms namely; bacteria, viruses, fungi, nematodes, mites, insects, mammals and other herbivorous animals are found in large amounts in all ecosystems, which lead to considerable reduction in crop productivity. These organisms are agents carrying different diseases that can damage the plants through the secretion of toxic-microbial poisons that can penetrate in the plant tissues. Toxins are injurious substances that act on plant protoplast to influence disease development. In response to the stress effect, plants defend themselves by bearing some substances such as phytoalexins. Production of phytoalexins is one of the complex mechanisms through which plants exhibit disease resistance. Several findings specifically on phytoalexins have widen the understanding in the fields of plant biochemistry and molecular biology. However, this review reports the interaction of toxins and phytoalexins in plant-pathogen cycle, research progress on the association of phytoalexins with plant disease resistance as well as the role of the phytoalexins in plant disease control.

PMID: 23052590 DOI: 10.1007/s00128-012-0853-y

This study aimed to find the association between urinary aflatoxin M(1) level and milk and dairy products consumption. Of 160 morning urine samples collected, aflatoxin M(1) was detected in 61.3 % samples (n = 98) [mean ± SD = 0.0234 ± 0.0177 ng/mL; range = 0-0.0747 ng/mL]. Of these positive samples, 67.3 % (n = 66) had levels above the limit of detection. Respondents with intake of milk and dairy products above median (67.79 g/day) had significantly high level of AFM(1) compared to those with low intake. A significant and positive association (φ = 0.286) was found between milk and dairy products consumption and urinary aflatoxin M(1) level.

Venom is a mixture of biologically active toxins that affect normal physiological functions. With the advance in technology, the complexity and functions of venom and its toxins are slowly being revealed. It has become important source for therapeutic, diagnostic and cosmetic agents. However, there is concern among the Muslim community pertaining to halal and safety issues on the venom and venom-derived product usage. There are few studies that discuss the Islamic views in the usage of venom and venom-based product in medicine and cosmetic applications. There is a need for Muslim scientists and scholars to seriously identify the potential ethical and safety issues in the usage of venom and venom-derived products in view of the widespread application in medicine and cosmetic, which subsequently forming the basis for relevant and reliable shariah ruling. This is an attempt to review the relevant articles based on the following keywords: venom and Islamic ruling, venom-based product, venom and medicine, venom and cosmetic, antivenom, venom toxin, snake poison and venom diagnostics. It will also attempt to clarify and elaborate the implication of the “halal” status for venom-based product. Finaly the current available shariah rulings on the usage of venom and venom-based product both in medical and cosmetic area and the related principle of fiqh involved will be analyzed. The findings from this review, particularly the current available ruling will allow various parties to be well informed on the current ruling and related issues on the usage of this products.
