ed from Public Health Dispatch, MMWR, Morbidity and Mortality Weekly Report, Vol. ٥٠ Oct ١٢, ٢٠٠١ CONTRIBUTION OF ENVIRONMENTAL FACTORS TO THE RISK OF MALE INFERTILITY In creasing number of reports suggest that chemical and physical agents in the environment introduced and spread by human activity may affect male fertility in humans. The relationship between exposure to environmental agents and...

Ciguatera fish poisoning (CFP) is a foodborne illness caused by fish containing ciguatoxin (CTX). The toxin is produced by the microalgae Gambierdiscus spp. which are then eaten by reef fish; humans contract the illness when eating either fish that have eaten the algae, or carnivorous fish that have eaten those fish. CTX is an odorless, tasteless, and colorless neurotoxin that blocks voltage-se...

background: botulism is caused by a neurotoxin produced from the anaerobic, spore forming bacterium clostridium. food-borne botulism is one of the dangerous forms of food poisoning in the world. the purpose of this study was to survey some clinical presentations and laboratory findings in patients suspected with botulism toxicity that had received anti-botulism. methods: this descriptive-retros...

Chick poisoning induced by oral administration of toxic fish tissues or extracts gave rise to internal hypersalivation, decrease in weight and acute motor ataxia. Detoxification was low and repeated administration therefore led to toxin accumulation. Response of the chicken to liver feeding was roughly quantitative; so liver, which is the most potential toxic tissue, may be used for a preventiv...

marine polyether ladders (Figure 1 and Figure 2) can be grouped into 14 backbone structures and has gained much notoriety in being responsible for countless cases of human food poisoning and massive fish kills. Maitotoxin itself displays the highest toxicity of any nonproteinaceous natural product isolated thus far. The biogenesis of the polyether ladders, whilst attracting speculation, has adv...

Mercury exists in various chemical forms. The important forms from a toxicological viewpoint are the metallic form, also called the elemental form, the divalent inorganic forms and methylmercury compounds. Elemental (Hg0) mercury has a high vapor pressure and the vapor causes a number of cases of poisoning via inhalation. Classical mercury poisoning is characterized by a triad of signs, namely ...
