Pedigree analysis in the Brazilian Zebu breeds.
Zebu breeds play an important role in cattle production systems in Brazil. To assess the genetic variability from animals in the Herd Books of Nelore, Gir and Guzerat breeds, generation intervals, inbreeding, effective population size and parameters of gene origin (effective number of founders, ancestors and founder genomes) were calculated using pedigree records from 1938 to 1998. Breed subdiv...
متن کاملHistomorphometric evaluation of mice testicular tissue following short- and long-term effects of lipopolysaccharide-induced endotoxemia
Objective(s):Lipopolysaccharide (LPS)-induced endotoxemia is known to cause male infertility. This study was designed to explore the effects of bacterial LPS on histomorphometric changes of mice testicular tissues. Materials and Methods: In experiment 1, a pilot dose responsive study was performed with mice that were divided into five groups, receiving 36000, 18000, 9000, and 6750 µg/kg body...

متن کاملHistomorphometric evaluation of skeletal development.
Hylonome dimensional relationships change little 2,3. Concomitant with the increase in bone size, the internal structure is modified. The average thickness of trabeculae in the proximal femoral metaphysis increases by about a third during the second half of gestation 4. Cortical thickness at the femoral midshaft approximately doubles during the same period 2. Histomorphometric studies of rib an...
متن کاملEffects of camphor on histomorphometric and histochemical parameters of testicular tissue in mice
Background: In traditional medicine of some Asian countries it is believed that camphor could act as a sexual depressant. However, limited studies have been published on this issue. OBJECTIVES: In the current study, effects of camphor on testes, sperm and serum factors, and roles of vitamin E as antioxidant in treatment of toxicity of camphor for testes were studied. METHODS: Fifty adult male m...
