BALB/c mice were vaccinated by the intramuscular (i.m.) and subcutaneous (s.c.) routes with a native preparation of the Chlamydia trachomatis mouse pneumonitis (MoPn) major outer membrane protein (MOMP), using Montanide ISA 720 and CpG-1826 as adjuvants. A negative control group was immunized with ovalbumin and the two adjuvants, and a positive control group was immunized intranasally (i.n.) wi...

A QTL analysis of female reproductive data from a 3-generation experimental cross between Meishan and Large White pig breeds is presented. Six F(1) boars and 23 F(1) sows, progeny of 6 Large White boars and 6 Meishan sows, produced 502 F(2) gilts whose reproductive tract was collected after slaughter at 30 d of gestation. Five traits [i.e., the total weight of the reproductive tract, of the emp...

Breakthrough bleeding (BTB), a major side effect of long-acting progestogen (p)-only contraceptives in women, is the main reason for discontinuation of their use. To understand the mechanisms of BTB, a mouse model of endometrial breakdown and repair was adapted to evaluate the effects of long-term progestogens on the endometrium. Appropriately prepared mice received either an etonogestrel (ENG)...

IN 1956, Csapo put forward the theory of the local action of placental progesterone in an attempt to explain the separate delivery of human twins, several weeks apart. This theory, which holds that progesterone from the placenta can reach the overlying myometrium by a direct route and produce a functional asymmetry ofthe uterus, has been criticised (Short, 1960) on the ground that such progeste...

The objective of this study was to highlight the postnatal development of the uterine tubes of the West African Dwarf goat from birth to 28 weeks of age by gross examination and light microscopy. There was a caudal migration of the paired uterine tubes from behind the paired kidneys at birth to the pelvic inlet at week 8 of age. Each uterine tube exhibited three segments namely; infundibulum, a...

The immune system in the upper reproductive tract (URT) protects against sexually transmitted pathogens, while at same time providing tolerance responses allogenic sperm and developing fetus. uterine environment is also responsive to hormonal variations during estrus cycle, although most likely timing of exposure pathogens breeding when cervix semi-permissive. goal for intrauterine immunization...

Plan: The present study was undertaken to investigate the H2 receptor antagonistic action of fresh juice of Brassica oleracea var. capitata Methodology: Two sets of experiments consisted of recording the responses of the uterine horn preparations (precontracted with potassium chloride, KCl) to histamine (4.5; 9; 17.99; 35.99; 71.98 × 10 and 14.40× 10 mol/L, 2 minute each concentration) in absen...

A substantial loss of embryos occurs between Days 30 and 40 of pregnancy in the pig under crowded intrauterine conditions, but it is not clear whether this loss affects the growth of adjacent conceptuses. Birth intervals are known to increase with decreasing litter size, but the factors responsible are unknown. Two possibilities are that increased birth weight associated with reduced litter siz...
