Abstract

Introduction: Rice tablet (aluminum phosphide:ALP) are an inorganic substance that is used as an insecticide and rodenticide in grain storage and transportation. It liberates lethal phosphine gas when it comes in contact either with atmospheric moisture or with hydrochloric acid in the stomach. ALP poisoning may be associated with serious and sometimes incurable complications.  Considering the large number of suicides and poisonings, especially the suicides of young people with aluminum phosphide, and the lack of sufficient information about the prevalence of aluminum phosphide poisoning in Mazandaran province, the aim of this study, is to assess of complications leading to deaths in patients with aluminum phosphide poisoning referred to the forensic medicine of the Mazandaran province and also to check the registration rate of the midbrain sample compared to other samples.


Materials and Methods: In this study, 27 deceased people were determined by a history of poisoning with certain rice tablets, and then a silver nitrate test was conducted on gastric content of all cases. Then the sample of gastric contents and the liver sample along with the midbrain sample were sent to the laboratory and the results are compared. After collecting the data, the data will be entered into SPSS18.


Results: The frequency distribution of the samples separately was based on the samples taken from the liver, stomach and midbrain sections. It was found that 68%, 47% and 32% of the samples was positive in the stomach, liver and midbrain respectively.


Conclusion: According to the findings, the midbrain is a helpful sample, and in cases where the midbrain sample is positive along with the positive liver and stomach samples, it can indicate the true positivity of the presence of phosphine in the midbrain.
