February 2011, Vol. 101, No. 2 SAMJ A 30-year-old woman was seen at 24 weeks for a discrepancy between the symphysis-fundal height and the gestation by dates. Ultrasound examination revealed a twin pregnancy and showed the placentas to be implanted ‘back-to-back’ over what appeared to be a septum that extended from the uterine fundus to the cervix (Fig. 1). A bicornuate unicollis uterus was con...

The aim of the present study was to describe the temperature of the different portions of the female genital tract and their relation to rectal temperature and to investigate the effect of steroid hormones profiles on these variables over the estrous cycle in cattle. Four nonpregnant Japanese Black cows were investigated daily over two successive estrous cycles using a digital thermometer with ...

background: hyperprolactinemia is a common side effect of antipsychotic drugs that requires further investigation. the current study was designed to evaluate dose-dependent effect of chlorpromazine (cpz) on hormonal changes and uterine horn histological structure in rats. moreover, the mammary glands were analyzed to show hyperprolactinemia-induced histological changes. methods: albino wistar r...

Mice with the type I interferon (IFN) receptor gene knocked out (IFNAR KO mice) or deficient for alpha/beta IFN (IFN-α/β) signaling clear chlamydial infection earlier than control mice and develop less oviduct pathology. Initiation of host IFN-β transcription during an in vitro chlamydial infection requires interferon regulatory transcription factor 3 (IRF3). The goal of the present study was t...

Placenta plays multi-functions in embryo-uterine dialogue through facilitating gas and nutrient exchange, providing an immunological barrier between the fetus and mother and secreting hormones and growth factors to regulate pregnancy. The successful formation and development of placenta requires invasion and differentiation of trophoblast cells, and any defects would result pregnancy related di...

This study was designed to examine the effects of oestradiol (E2) on sperm transport in the swine uterus. The bicornuate swine uterus is optimal for the study of the uterine transport and peristalsis because the influence of various factors can be examined on each uterine horn independently. Forty swine uteri (with or without ovarectomy) were perfused for a period of up to 7 h. Two different E2...

A divergent selection experiment on within-litter homogeneity of birth weight in rabbits was carried out at the INRA experimental farm at Auzeville. The two lines were created by selecting breeding does and bucks from the female strain AGP22 bred at the Grimaud Frères Sélection Company. This involved a new model incorporating a genotypic value for the mean of individual birth weight and a genot...
