Tramadol as a centrally acting analgesic is extensively used in the management of moderate to severe pain. It slightly affects opioid receptors and inhibits the reuptake of norepinephrin and serotonin in the CNS. There are reports about toxicity and abuse of tramadol. The objective of the present study was to evaluate epidemiology of intentional tramadol(More)
Studies suggest that some lead-induced toxic effects may occur through free radical production and oxidative stress. This study examined the relationship between brain histopathological alterations and oxidative stress in subchronic lead exposure. Male Albino rats received lead acetate at 0.01%, 0.05% and 0.1% w/v in their drinking water for 30 days.(More)
BACKGROUND Acute aluminum phosphide (AlP) poisoning is one of the most common cause of acute pesticide poisoning in Iran. Spontaneous ignition is a rare finding in AlP poisoning. OBJECTIVE To present two cases of fatal AlP poisoning that involved spontaneous ignition. CASE REPORT Two patients presented with suicidal ingestion of AlP tablets. In the(More)
Tramadol is an atypical opioid analgesic used in the treatment of mild to moderate pain. Despite being a GABA(A) agonist, seizures are a prominent complication with its therapeutic use, abuse or overdose. For patients who have had a tramadol-induced seizure, the likelihood of recurrent seizures and the need for emergent anticonvulsant prophylaxis is(More)
Aluminum phosphide (AlP) is a solid fumigant widely used in Iran as a grain preservative. When reacted with water or acids, AIP produces phosphine gas, a mitochondrial poison that interferes with oxidative phosphorylation and protein synthesis. Poisoning by AIP is one of the most important causes of fatal chemical toxicity in Iran. There are few studies in(More)
Pure submandibular saliva was collected intraorally by micro polyethylene cannulation of anaesthetized rats using pilocarpine as a secretagogue. Twenty-four days treatment with lead acetate 0.05% in drinking water altered salivary function. Except for flow rate that was (P<0.01) increased by lead acetate, the reminder of parameters, concentrations of total(More)
Aluminium phosphide (AlP) poisoning has a high mortality due to cardiovascular involvement. In this study, we evaluated the frequency of cardiac manifestations and electrocardiographic (ECG) findings in 20 patients with acute AlP poisoning, who were admitted to the intensive care unit (ICU) in Tehran, Iran, over a period of 6 months (between October 2008(More)
OBJECTIVE Aluminum phosphide is used as a fumigant. It produces phosphine gas (PH₃). PH₃ is a mitochondrial poison which inhibits cytochrome c oxidase, it leads to generation of reactive oxygen species; so one of the most important suggested mechanisms for its toxicity is induction of oxidative stress. In this regard, it could be proposed that a drug like(More)
INTRODUCTION Acute aluminum phosphide (AlP) poisoning is one of the most common causes of acute pesticide poisoning in Iran. Hydrogen phosphide or phosphine gas is produced following reaction of AlP with water even at ambient humidity. Methemoglobinemia is a rare finding following phosphine poisoning. In this paper, two cases of fatal AlP poisoning(More)
The aim of this article is to provide a brief review of the current status of our knowledge related to organophosphates (OPs) and oxidative stress. For this purpose, we performed a systematic review on the literatures using Pubmed and Scopus databases without date limitation. A total of 127 articles including 112 experimental and 15 human studies were found(More)
