[ 1 ] - Vitamin C Can Alter Lead-Induced Passive Avoidance Learning Impairment in Rats

Introduction: Lead (Pb) is a neurotoxin that its different effects on the central nervous system are well-known. Previous studies have reported the potent effects of vitamin C on memory.The present study was undertaken to evaluate the protective effects of vitamin C against leadinduced amnesia. Methods: Male Wistar rats were divided into 4 groups: the control (saline), negative contr...

[ 2 ] - Opioid Receptors Gene Polymorphism and Heroin Dependence in Iran

Introduction: Genes often have multiple polymorphisms that interact with each other and the environment in different individuals. Variability in the opioid receptors can influence opiate withdrawal and dependence. In humans, A118G Single Nucleotide Polymorphisms (SNP) on μ-Opioid Receptor (MOR), 36 G>T in κ-Opioid Receptor (KOR), and T921C in the δ-Opioid Receptor (DOR) have been...

[ 3 ] - مقایسه اثر N-استیل سیستئین و ویتامین D بر سمیت اکسیدانی بافت کبد در مسمومیت تحت حاد با پاراکوات

سابقه و هدف: پاراکوات عمدتاً به عنوان علف­کش به کار می­رود و سمیت آن از طریق افزایش گونه­های فعال اکسیژن می­تواند مسبب بیماری کبدی حاد و مزمن شود، این مطالعه به منظور مقایسه اثر N-استیل سیتئین (NAC) و ویتامین D (Vit D) بر سمیت اکسیدانی بافت کبد در مسمومیت تحت حاد با پاراکوات انجام شد. مواد و روش­ها: در این مطالعه تجربی 36 موش صحرایی نر ویستار آلبینو 8 هفته­ای به‌صورت تصادفی به 6 گروه تقسیم شدند:...

[ 4 ] - The Role of Allium saralicum Extract on Prevention of Acetaminophen-Induced Hepatic Failure: an Experimental Study

Background and objectives: Acetaminophen (APAP) is a common analgesic medicine whose overdose leads to severe hepatic dysfunction. Due to the known antioxidant properties of Alliumspecies, the present study aimed to evaluate the protective effects of Allium saralicum plant on APAP induced liver toxicity. Methods: The hydro-alcoholic e...

[ 5 ] - The Effects of 3,4-methylenedioxymethamphetamine on Neurogenesis in the Hippocampus of Male Rats

Introduction: The administration of 3,4-methylenedioxymethamphetamine (MDMA) or ecstasy causes memory impairment, whereas neurogenesis improves memory and learning. Hence, this study evaluated the effects of MDMA on neurogenesis in the hippocampus of male rats. Methods: Adult male Wistar rats received intraperitoneal (IP) injections of MDMA (10 mg/kg). We assessed nestin, sex-determining regio...
