background: nandrolone decanoate (nd) is an anabolic androgenic steroid (aas) which influences the ovarian structure and function. we assessed the effects of nd on the ovarian volume, number of primordial follicles, and level of hormones and also evaluated the modulatory effects of gonadotropins on the histopathological changes imposed by the administration of nd. methods: six groups of sprague...

Background: Lead is known to be a highly toxic heavy metal which has a wide range of effect on human health. It has been proven that probiotics are able to bind heavy metals and remove them from the environment. In this study, the effect of Lactobacillus fermentum (L. fermentum) and its cytoplasmic extract were investigated on the hematological and body weight parameters in lead exposed rats. ...

Although microorganisms are degrading the contaminants in bioremediation processes, soil animals can also have important--while usually an indirect--role in these processes. Soil animals are useful indicators of soil contamination, both before and after the bioremediation. Many toxicity and bioavailability assessment methods utilizing soil animals have been developed for hazard and risk-assessm...

It had been demonstrated that Glycyrrhiza glabra extract has biological capabilities include detoxication, antioxidation and antiinfection properties, although there is little data available about its probable side effects on the liver integrity. So, the effects of G. glabra administration on the liver ́s histology and some biochemical parameters were investigated in the rats. Thirty-two Sprague...

VASOPRESSOR. agents produce renal vasoconstrie.tion when administered to normotensive animals and man." Because of this vasoconstrictor activity, the question has been raised whether these agents might not actually be harmful' G to the kidney when used to elevate blood pressure for the treatment of shock. Observations made recently' s indicate that when renal and cerebral blood flow are markedl...

background: recently, there are increasing concerns and interests about the potential effects of electromagnetic field (emf) on both human and animal health. objective: the goal of this study was to evaluate the harmful effects of 50 hz non-ionizing emf on rat oocytes. materials and methods: in this experimental study 30 rats were randomly taken from laboratory animals and their ags and weights...

People, domestic animals, and wildlife are all exposed to numerous environmental threats, including harmful algal blooms (HABs). However, because animals exhibit wide variations in diet, land use and biology, they are often more frequently or heavily exposed to HAB toxins than are people occupying the same habitat, making them sentinels for human exposures. Historically, we have taken advantage...

the use of chloramphenicol is prohibited in food producing animals due to its harmful and even potentially fatal side effects in human. in order to screen broiler carcasses for the drug residues, 31 broiler chickens from different farms were sampled. the samples from kidneys were homogenized, extracted using ethyl acetate and dried under n2 flow. the samples were then assayed using enzyme-linke...
