Amount of environmental lead pollution is increased with progression of industry. This pollution is able to damage the living beings in many ways. Blood and Immune systems are more sensitive to toxic effects of lead. 30 female and 6 male rats from Sprague dawley race are chosen by simple random sampling. After copulation and vaginal plug observation, expectant rats are calssified in test and co...
The relationship between dietary fat and mammary carcinogenesis was examined by feeding a high-fat or a low-fat purified diet, differing only in fat and carbohydrate content, to Fischer, Long-Evans, and Sprague-Dawley rats. An additional group of rats from each strain was fed a nonpurified laboratory diet for comparison. The rats were given an i.v. dose of A/-nitrosomethylurea (50 mg/kg body we...

This study investigates changes in systolic and diastolic blood pressure Sprague Dawley rat dams exposed to postpartum stress. Eighteen pregnant were randomly divided into three groups: Control (C, n = 6, no-stress), Maternal Separation (MS, 6), Brief (BMS, 6). The pups group C housed under standard conditions their cages at the animal facility during period. From day 2 14, MS BMS separated fro...
The Dahl salt-sensitive rat (SS/Jr) is a widely used animal model of salt-sensitive hypertension. SS/Jr rats are believed to be highly inbred and uniformly sensitive to the hypertensinogenic effects of sodium chloride, but we have recently observed that SS/Jr rats from Harlan Sprague Dawley, Inc, exhibit considerable variability in their blood pressure response to supplemental dietary salt. To ...
in this investigation, diabetes was induced in adult male sprague-dawley rats by single intraperitoneal injection of streptozotocin (stz) at 45 mg kg-1 of body weight. a group comprised of 8 diabetic rats was treated with metformin at 100 mg kg-1 of body weight for reducing the elevated blood glucose level. the results revealed that, in the untreated diabetic rats, the body and testicular weigh...
