This study was conducted to assay the use of Saturejahortensis L. (savory) essential oil in the drinking water on broiler production and blood glucose, uric acid, creatinin and cholesterol. Four hundred and twenty day old broiler chickens (Ross 308) was used in a completely randomized design with 6 treatments and 5 replicate. Experimental treatments included: 1) control, 2) Tween (a solvent for...

Thirst is a sensation normally aroused by a lack of water and associated with a desire to drink water. The mechanisms involved in the control of drinking are useful to study, not only because of their clinical relevance, but also because the stimuli that lead to drinking can be identified, measured and manipulated, so allowing the basis of a relatively complex, motivated behaviour to be analyse...

Vanadate, a potent naturally occurring Na+,K+-ATPase inhibitor thought to have a role in regulating Na+-K+ pump activity, was fed to uninephrectomized rats drinking tap water or a 1% solution of sodium chloride for as long as 56 weeks. Feeding was achieved by adding sodium orthovanadate to normal rat chow equivalent to 100 or 200 ppm vanadium by weight. In the rats drinking tap water, systolic ...

Background: Providing safe drinking water has critical importance to human societies. The aim of this study was to investigate microbiological quality of drinking water in distribution system of urban and rural regions of Ijroud, in Zanjan province.   Materials and Methods: In present descriptive study, the microbiological examination of drinking water was conducted in 15 facilities with...

BACKGROUND Developmental exposure to polychlorinated biphenyls (PCBs) or methylmercury (MeHg) can result in a variety of neurotoxic effects, including long-term auditory deficits. However, little is known about the effects of combined exposure to PCBs and MeHg on auditory function. OBJECTIVE We developmentally exposed rats to PCBs and/or MeHg and assessed auditory function in adulthood to det...

It has recently been demonstrated that developmental exposure to methylmercury (MeHg) is associated with perseveration on operant tasks. An understanding of the behavioral mechanisms underlying this phenomenon may improve human testing of MeHg exposures and could provide insight into clinical syndromes that include perseveration as a component. One possible mechanism is that MeHg-induced enhanc...

Chronic administration of vinyl acetate (VA) in drinking water to rats and mice has produced upper digestive tract neoplasms. These tumors were believed to arise from the intracellular metabolism of VA by carboxylesterases to cytotoxic and genotoxic compounds. We hypothesized that prolonged VA exposure at high concentrations would induce cytotoxicity and a restorative cell proliferation (CP). T...

We have previously demonstrated that diphenylarsinic acid (DPAA) promotes liver carcinogenesis in rats in a medium-term liver carcinogenicity bioassay. However, the effects of DPAA on other organs have not been determined. In the present study, the effects of DPAA on carcinogenesis were investigated using a rat multiorgan carcinogenicity bioassay. A total of 60 six-week-old male F344 rats were ...
