The prevalence of this disease in Iran is approaching the European level. Astrocyte cells are nerve tissues that regulate the immune system activity by secreting various cytokines such as IL- 17.  The aim of this study was partial purification of toxin from M.eupeus scorpion venom that has immunomodulatory effect on astrocyte cell line (1321N1) Materials and Methods: In the present study, purified crude venom of M.eupeus scorpion. Size exclusion and reverse-phase high-performance liquid chromatography was used for fractionation. The fractional molecular weight was determined by Using SDS and Tricine electrophoresis, Astrocyte cells (1321N1) were selected as functional cells in testing the immunomodulatory effect of venom. The viability of cells were determined by MTT and LDH assays. Astrocyte cells were activated by lipopolysaccharide and the release of interleukin-17 in activated cells was estimated using ELISA kit. Results:  fraction 331 (F331) from RP-HPLC contain the purified peptide with molecular weight of about 4500 Dalton. When activated cells exposed to purified peptide the rate of interleukin-17 release was found to be 85 pg/ml which is almost similar to un-activated cells (78 pg/ml). However in activated cells by LPS without treatment with purified peptide the rate of IL-17 release was found to be 147 pg/ml which was significantly (p <0.05) higher than control group.   Conclusion: The purified peptide (F331) from   venom of Mesobouthus eupeus can inactivate the astrocyte 1321N1 cells activated by LPS as indicated by decreased secretion of IL-17 from the cells.","PeriodicalId":30463,"journal":{"name":"Asia Pacific Journal of Medical Toxicology","volume":"9 1","pages":"52-59"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48310670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the use of adulterants can overlap or exacerbate the symptoms of cocaine intoxication hindering the diagnosis. This case shows how the morbidity and mortality of inhaled cocaine consumption adulterated with caffeine can increase by generating unusual severe rhabdomyolysis and rare serious complications. Case presentation: 31-year-old Hispanic male, single, construction worker, generally healthy except for the past history of inhaled cocaine hydrochloride dependence, who after three days of cocaine snorting presented profound altered state of consciousness and multiple complications,   liver damage, kidney failure and severe rhabdomyolysis (CPK=657625 U/L, troponin=3.6, potassium=6 mEq/L). After fourty-five days in the ICU, the patient stayed for two more months hospitalized for the treatment of healthcare-associated infections before being discharged without sequelae. An analysis of the powdered substance consumed by the patient confirms the presence of caffeine as cocaine adulterant. None other additional substance was detected in the sample. Discussion. This clinical case describes serious complications presented by the excessive consumption of cocaine adulterated with caffeine. Notably, most of the complications herein described were of unexpected severity and duration for an acute cocaine intoxication.  This case can suggest that in patients suffering from cocaine who have severe rhabdomyolysis, a simultaneous consumption of adulterants such as caffeine should be considered.","PeriodicalId":30463,"journal":{"name":"Asia Pacific Journal of Medical Toxicology","volume":"9 1","pages":"77-80"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49618658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A few researches showed that the most common route were ingestion of lead contaminated opium in these patients. However, some use of inhaler opium and data on lead poisoning through this route is scarce. The aim of the current study was to determine lead poisoning in opium users who consume it inhalational. Methods: In this case-control study, blood lead level (BLL) and clinical Lead poisoning assessed and compared between pure inhalational and pure ingestionally chronic opium users and healthy controls. Results: There were totally 90 cases, 30 patients in each group (pure inhaler opium users, pure oral opium users, and control group). In chronic opium users (case group), mean age of the patients was 48.91±13.14 yeas (range; 22 to 79 years). Eighty-four (85%) patients were male (Male to Female ratio; 5.6/1).

Aluminum phosphide (ALP) is a highly toxic solid fumigant pesticide, rodenticide and insecticide. It is commonly used as outdoor and indoor pesticide in developing countries like India, Pakistan, Srilanka and Iran because it is a cheap, effective, free from toxic residue and do not alter the viability of seeds. Aluminium Phosphide (ALP) is a highly toxic fumigant which is used commonly as an indoor pesticide in agriculture based industry for storage of grains. ALP on ingestion reacts with a gastric water and release phosphine gas, which is highly flammable, and very toxic in nature. Over the last few decades ALP has emerged as an agent of choice being used as suicidal poisoning in a country where it is readily available. The high mortality rate is due to severe mitochondrial dysfunction leading to disruption of cellular respiration, causing tissue hypoxia and organ dysfunction.

We aimed to study the spatial distribution of poisoned patients and its risk factors in Mashhad, Iran.Methods: This was a retrospective cross-sectional study of patients treated at the Medical Toxicology Center, Imam Reza Hospital, Mashhad, Iran, which is the only referral center in northeastern of Iran in 2013. Negative binomial and Poisson approach via generalized linear mixed models were performed to investigate the association between socio-demographic and environmental characteristics with the number of reported cases of poisoning.Results: A total of 5064 poisoned patients (52% females) were included. Most of the poisoned patients were within the age group of 20-29 years old (41.4%). Drugs were the most common cause of poisonings (64.6%). The local test of spatial autocorrelation (Moran’s I) confirms that the poisoning has cluster pattern in Mashhad. Positive relationships were found between poisoning frequency, population density (RR= 1.00011; 95% CI 1.0001-1.00013), the number of health centers (RR= 1.10; 95% CI 1.03-1.17) and percent with less educational background (RR=1.49; 95% CI 1.32-1.68).Conclusion: Drug poisoning was the most common causes of poisoning in this study. Moreover, socio- and environmental characteristics were associated with poisoning frequency in different areas, which could be vital for policy and decision makers when planning.
