histopathology on the olfactory organ of a snakehead fish, channa punctatus (bloch, 1793) were assessed after exposing the fish to 2.5 mg/l and 5mg/l of cdcl 2 for 15 days, 30 days and 45 days. cellular organization of the epithelium was affected severely with degeneration of sensory and supporting cells and hyperplasia of basal cells and mucous cells. mucous cell proliferation indicates the up...

This study was performed to investigate the protective and therapeutic effects of resveratrol (RES) against CdCl2-induced toxicity in rat testes. Seven experimental groups of adult male rats were formulated as follows: A) controls+NS, B) control+vehicle (saline solution of hydroxypropyl cyclodextrin), C) RES treated, D) CdCl2+NS, E) CdCl2+vehicle, F) RES followed by CdCl2 and M) CdCl2 followed ...

Metals are being utilized of ways in industries and agriculture; particularly heavy metals such as Mercury, Lead, Arsenic and Cadmium constitute a significant potential threat to human health because they are associated to many adverse effects on health. Due to the increasing pollution, concentrations of various chemical compounds have increased in aquatic environments. Water contaminants have ...

Cadmium (Cd) is one of the most toxic environmental heavy metals to organisms. The prominent toxic effects of Cd on reproductive organs are very well known. Gonad histopathology is a valuable tool for the assessment of endocrine disruption compounds EDCs effects on fish. The aim of this study was to evaluate the reproductive toxicity of cadmium chloride (CdCl2) on histopathology of Zebrafish (D...

Cadmium is a heavy metal of considerable toxicity with destructive impact on most organ systems. It is widely distributed in humans, the chief sources of contamination being cigarette smoke, welding, and contaminated food and beverages. Toxic impacts are discussed and appear to be proportional to body burden of cadmium. Detoxification of cadmium with EDTA and other chelators is possible and has...

organization of various cells lining the olfactory mucosa of puntius ticto (hamilton, 1822) were described by light as well as scanning electron microscopy. the paired olfactory chambers located antero-dorsal to the eyes and communicated outside through anterior and posterior nasal openings. the oval shaped olfactory rosette lied at the bottom of chamber and composed of 18-20 lamellae arranged ...

Cadmium poisoning has been reported from many parts of the world. It is one of the global health problems that affect many organs and in some cases it can cause deaths annually. Long-term exposure to cadmium through air, water, soil, and food leads to cancer and organ system toxicity such as skeletal, urinary, reproductive, cardiovascular, central and peripheral nervous, and respiratory systems...

Background: Cadmium is known as a unique heavy metal compared to others, due to its long half-life, low discharge from the body, toxicity at low concentrations and accumulation in tissues. Methods: The effects of chronic and acute Cadmium (Cd) exposure were investigated on the morphology and histopathology of 24 field rats (Millardia meltada). The rats were divided into two groups of 12 each, ...

Intranasal exposure to the heavy metal cadmium has been linked to olfactory dysfunction and neurotoxicity. Here, we combine optical imaging of in vivo neurophysiology, genetically defined anatomical tract tracing, mass spectrometry, and behavioral psychophysical methods to evaluate the persistent harmful effects of acute intranasal exposure to cadmium in a mouse model and to investigate the fun...
