The study of the effect on the internal organs of mice of the application of carcinogenic agents to the skin has occupied our attention during recent years, a preliminary analysis of findings in several thousand animals having already been published (1). Most of these earlier experiments were performed with the primary object of testing the reaction of the skin to various carcinogenic agents. M...

PURPOSE To evaluate changes in body and internal organ weight of autopsied children in the perinatal period and their relationship with the cause of death. METHODS One hundred and fifty three cases of perinatal autopsies performed at a university hospital in Southeastern Brazil ere included. Information about cause of perinatal death, date of autopsy, gestational age, perinatal weight and org...

background: modulation of the immune response is an important strategy by which establish­ment and growth of hydatid cyst in the internal organs of human is warranted. induction of apop­tosis in the lymphocytes might be a considerable component. this study was designed to evaluate apoptotic impact of hydatid fluid (hf) on human lymphocytes. methods: human lymphocytes were treated with hydatid f...

Forty eight 8-month-old male goats were divided into three groups. In each group, eight goats were feedrestricted for 45, 60 or 75 days, and eight goats served as the control. Restricted groups were fed with a maintenance ration, and the control goats were fed with a ration supporting 50 g of daily weight gain. At the end of restriction period, the restricted goats were offered the same ration ...

This study was conducted to evaluate the effects of lavender (Lavandula angustifolia)extract as an alternative to flavophospholipol on performance, carcass characteristics, antioxidant status,meat quality, intestinal morphology and ileal microflora of broilers. A total of 220 day-old male broiler chicks (Ross 308) were used in a completely randomized design with five treatments each re...

Genomic imprinting underlying growth and development traits has been recognized, with a focus on the form of absolute or pure growth. However, little is known about the effect of genomic imprinting on relative growth. In this study, we proposed a random regression model to estimate genome-wide imprinting effects on the relative growth of multiple tissues and organs to body weight in mice. Joint...

Differences in growth, chemical body composition and visceral organ development were evaluated in three genetic stocks: Beltsville Highfat (HF) and Lowfat (LF) Duroc-Yorkshire composites and a Hampshire X Large White cross (CX). Ten sets of littermate barrows were used from each stock. One pig from each set was slaughtered at 10, 17 and 24 wk of age. After slaughter, each pig was dissected into...

in current study, a few sheep cystic livers and lungs were obtained from mashhad slaughter house and protoscolex were separated aseptically. thirty 6-week-old swiss mice were divided into 5 groups and two thousands of live protoscolices were inoculated intrapritoaneally in each mouse. in group 1 and 2 (prophylactic groups), mice were given 150 mg/kg of oral albendazole and mebendazole for 10 da...
