Toxicology deals with the measurement and analysis of toxins. It is itself a vast branch of science, though it has several branches and one of these is forensic toxicology. Forensic toxicology is a branch of toxicology that lines up with other disciplines, namely clinical chemistry, postmortem forensic toxicology, human performance toxicology and forensic drug testing, providing medical jurisprudence of adverse effects such as drug abuse, poisoning and death. The key role of forensic toxicology is to identify and analyse the toxin compounds found during adverse events. This review paper aims to draw an idea about the toxin, in the collected biological chemical samples such as urine samples and their effects on their day-to-day life

There is presented intrasphincetric injection management of achalasia, an esophageal dysmotility disorder involving an abnormal relaxation of the lower esophageal sphincter. Botulinum toxin A is a well-described treatment for achalasia, in patients who is contraindicated others modality due to comorbidity, especially in older age. We describe a case of a successful treatment of achalasia in the 83-old man with botulinum toxin A, as efficacy and very safe method for symptomatic relieve of these patients.

For the investigation of micromycetes-contaminants in children foods and their toxigenic activity, 173 samples of children foods traded in local markets in al-Hasakah governorate -northeastern Syria- were collected and tested during the period (2011-2012). The tested samples were included in 4 food groups: oily seeds (35 samples), potato & maize chips (53 samples), biscuits (45 samples) and powdered milk & sugars (40 samples).The Sample investigation was undertaken in the plant diseases laboratory in Al-Qamishli Agricultural Research Center. The results of the analysis showed that most of the samples tested were contaminated with fungi in varying degrees ranged between 1× 10² and 5×10⁷ spore / gram of food substance. Only 2.3% of the samples tested exceeded 10⁴ spore / gram of food substance.

A fucoidan with high ester sulfate content (38-40% by weight) has been isolated in a commercial scale process from Laminaria hyperborea harvested from the western coast of Norway. This is the first characterization of a fucoidan from this species of macroalgae. Ultra purified samples with negligible endotoxin levels were evaluated for cytokine expression in cultured human mononuclear cells.

BOTULISM is a neuro-paralytic intoxication illness caused by the ingestion of neurotoxins of Clostridium botulinum with contaminated water or food. The Gram-positive spore-producing bacterium Cl. botulinum is found worldwide and can survive in spore form for up to 30 years in numerous substrates in the environment. Cl. botulinum is classified into 7 or 8 different types (A, B, C (C1, C2), D, E, F, G) depending on the antigen properties of the botulinum neurotoxins (BoNT) produced, with intoxication mostly appearing in cattle following the ingestion of neurotoxins of type C and D and, less frequently, of type B.
