Background. ATP-sensitive K+ channels of the plasma membrane in smooth muscles uterus are one most significant ion that regulate excitability this tissue both non-pregnant state and during pregnancy. MitoKATР-channels ensure regulation bioenergetic mitochondria (the intensity mitochondrial respiration potential inner membrane). Thus far, there is no information on participation types these mech...

In mammalian species there are significant physiological responses of the female reproductive tract to deposition sperm. These particularly notable in where sperm deposited directly into uterus, and function both facilitate transport reservoir, eliminate introduced contaminants. bitch, vagina rapidly transported through open cervix. Sperm then distributed around uterus by uterine contractions s...

Female reproductive anatomy of the Arabian oryx is unknown. In this study, reproductive tracts of seven female Arabian oryx (aged 2 to 7 years) were examined to characterize their reproductive anatomy. Observations and measurements were obtained in situ from dead animals during necropsy. Animals were allocated into two groups: cycling (n = 3; follicles or corpora lutea present) and not-cycling ...

OBJECTIVE To study the effects of tamoxifen versus tamoxifen plus 13-cis-retinoic acid on the histology of uterine glands in rabbits. METHODS The experimental, randomised, controlled trial was conducted at the Army Medical College, Rawalpindi, from March 2009 to June 2009 and comprised rabbits acquired from the National Institute of Health, Islamabad. The animals were randomly divided into th...

Background. According to existing knowledge, thiacalix[4]arene С-1087 is highly capable of inhibiting Са2+-pump (Са2+, Mg2+-АТРase) the plasma membrane; at same time it inhibits functioning sarcoplasmic reticulum uterine smooth muscles some degree. The aim this research was study effects on concentration Ca2+ ions and contractile activity rat myometrium cells using an inhibitor – thapsigargin. ...

Whole boar semen or seminal plasma has been demonstrated to advance the time of ovulation in gilts. As a means of clarifying this influence, the contribution of uterine lymphatics and their white cell populations has been examined. After duct visualisation with Evan's blue, lymph was sampled from a mesometrial vessel in eight pre-ovulatory gilts whose uterine lumen was infused simultaneously wi...

Influence of initial length of uterus available to each embryo on its subsequent survival and development was determined by systematic restriction of the length available to each potential embryo. Fifty-seven pregnant crossbred gilts were laparotomized at d 3 of gestation, length of uterine horns was measured in situ and corpora lutea (CL) were counted. In Exp. 1, uterine space available to eac...

A high prevalence of uterine leiomyoma has been reported in Baltic gray seals aged 15 years and above. Studies on Baltic seals during the 1970s revealed high tissue concentrations of the organochlorines bis(chlorophenyl)-1,1,1-trichloroethane (DDT) and polychlorinated biphenyls (PCBs), lowered reproduction rate, and pathologic changes. In the second half of the 1970s, decreases of PCB and DDT i...

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder marked by aplasia or hypoplasia of the uterus and vagina as result arrest in development müllerian ducts. Prevalence being 1 4000–5000 live births females. Leiomyoma most common uterine tumor, their occurrence from rudimentary females with MRKH very rare only few cases have been documented literature. Here we report 38-year...
