in human fertilization, the sperm centrosome nucleates a radial array of microtubules called the sperm aster. the sperm aster is responsible for apposition of male and female pronuclei, and later gives rise to the first meiotic spindle. the objective of this study was to determine microtubule assembly and chromatin configuration in rabbit oocytes following intracytoplasmic injection with human ...

a 2-year-old, female, crossbred pet rabbit was found to have a subcutaneous axillary abscess from which staphylococcus lentus was the sole isolate. the s. lentus - an indigenous bacterium in rabbit saliva - probably was introduced into the axillary region during licking of a small wound. due to severe neutropenia, the rabbit had developed a serious infection within a few weeks. marked clinical ...

The aim of the present study was to characterize the pituitary gonadotropin-releasing hormone (GnRH) binding site in the rabbit and investigate its possible role in sexual maturation of the female rabbit. A radioligand binding assay was established, and the presence of specific 125I-labelled D-Ala6-des-Gly10-GnRH ethylamide (125I-DAl6EA) binding sites in the anterior pituitary gland of the rabb...

Rabbit breeding is a special branch of animal husbandry characterized by high fertility and growth intensity. The main way intensification rabbit farming involves such selection measures that adapt populations keeping in industrial conditions, ensure reproductive properties female rabbits, preservation rabbits nests, rate, fattening meat qualities animals. research was conducted on the basis ex...

Rabbit farming is a powerful source of dietary meat, rabbit fluff, and skins. The research was conducted at the farm Precarpathian State Agricultural Research Station Institute Agriculture Carpathian Region National Academy Agrarian Sciences. article describes creation new highly productive genetic populations rabbits identified as best options for crossing maternal paternal forms. Three breeds...

quality and quantity of ovum are major determinants in invitro fertilization. the aim of the present study was to determine effect of the time of oocyte collection and also distance of hcg injection to oviduct flushing on the quantity, quality and fertilizing ability of rabbit oocyte. accordingly, sixty two adult female rabbit selected and randomly allocated to seven groups. the rabbits were su...
