contain 5.1 g. of 3-ethylpentane by vapor phase chromatography. The above material was purified by shaking with potassium permanganate solution followed by vapor phase chromatography ($6~ 1.3929). Final purification was effected by dissolving it in 10 ml. of acetic acid and adding solution of sodium dichromate and perchloric acid in 90% acetic acid until the orange color persisted. Water was ad...

Increased DNA-protein cross-linking (DPX) in circulating leukocytes has been proposed as a potential biomarker for exposure and genotoxic damage caused by inhalation of certain reactive chemicals, such as hexavalent chromium [Cr(VI)]. This study was designed to determine whether ingestion of a single dose of potassium dichromate alone [Cr(VI)] or potassium dichromate fully reduced to Cr(III) wi...

This study carried out to understand the effects of Potassium Dichromate (K2Cr2O7) and Turmeric Oil (TO) on reproductive efficiency. Twenty four weanling immature female albino rats aged 22 day divided randomly into 4 groups (6 rats in each group). 1 group received 0.1 ml dimethyle sulfoxide (DMSO) 5% solution as a control (I/P for 14 day), 2 group received K2Cr2O7 dissolved in distilled water ...

Eimeria belonging to the phylum apicomplexan protozoa is recognized as the the major parasitic disease of poultry. Caecal coccidioisis caused by Eimeria tenella is a major threat to poultry production. The drugs which can inhibit sporulation process are best choice as preventive measures. Anticoccidial drugs have played a major role in the effective control of avian coccidiosis, but their exten...

BACKGROUND/PURPOSE Occupational dermatitis among cement workers is a major occupational health concern.

Chromium (Cr) is an element present in nature mineral form. It has a dual effect, both as essential micronutrient and carcinogenic agent depending on its chemical form concentration. various environmental matrices such water, soil, air, coming from natural anthropogenic sources, causes harmful effects biota, ecosystems, even human beings. This study's objective was to evaluate chromium toxicity...
