The aim of this work was to determine if the inhibition or stimulation of NO synthesis modulates liver damage induced by chronic lead intoxication. Lead nitrate (3.6 mg/kg, per os) was administered one time a day for 30 days to male Wistar rats with low and high resistance to hypoxia treated simultaneously with L-arginine (600 mg/kg, i.p.) or N-nitro-L-arginine (L-NNA, 35 mg/kg, i.p.) 30 min. b...

The honey produced by the bees fed on Rhododendron family plants containing grayanotoxin is known as mad honey in our country. This intoxication is seen rarely. However, it may lead life-threatening hemoinstability mentioned above and may be confused with various diseases. For these reasons the exact diagnosis and treatment of this intoxication seems very important. We aim to describe a case ad...

Introduction/Objective. Lead exposure represents one of the most important factors that affect general health, including oral health and it is associated with enamel dentin tooth defects. The aim this paper was to determine expression fibronectin in pulp rats experimentally induced diabetes mellitus (DM), after lead exposure, by using immunohistochemical analysis. Methods. study conducted on 42...

The antidepressant venlafaxine in overdose can lead to serotonin syndrome, seizures, QTc interval prolongation and can increase the risk of cardiac arrhythmias. It has been reported to be more toxic in overdose than other new antidepressants. We report a case of venlafaxine intoxication with a venlafaxine/O-desmethylvenlafaxine serum level of 2861/2670 ng/mL 22 h after ingestion. This is one of...

Lead intoxication was first associated with increased coproporphyrin excretion almost 100 years ago; but not until the 1930's were abnormalities in blood protoporphyrin detected. These later findings have been interpreted as an inhibition by lead of iron incorporation into protoporphyrin during heme synthesis. The testing and application of this hypothesis had to await three more decades of res...

BACKGROUND With increases in globalization, cultural remedies from Chinese, Ayurvedic, Arab and other traditions have become more available to international consumers, offering unfamiliar "Natural Health Products" (NHP), used as alternative medicine or supplementary medicine. Contamination with toxic ingredients including lead, mercury, arsenic, and other toxic elements has been documented in s...

We have reported that chronic lead intoxication under hypoxic environment induces alveolar bone loss that can lead to periodontal damage with the subsequent loss of teeth. The aim of the present study was to assess the modification of oral inflammatory parameters involved in the pathogenesis of periodontitis in the same experimental model. In gingival tissue, hypoxia increased inducible nitric ...
