introduction: morphine withdrawal syndrome is mediated via several central and peripheral neurological pathways. in the present study we investigated the role of n-methyl-d aspartic acid (nmda) glutamate receptor on naloxone-induced withdrawal syndrome in morphine-conditioned mice. materials and methods: we designed two separate experiments. in experiment one, 30 male nmri mice were divided int...

AT-rich interactive domain 1A gene (ARID1A) loss is a frequent event in endometriosis-associated ovarian carcinomas. Endometriosis is a disease in which tissue that normally grows inside the uterus grows outside the uterus, and 50% of women with endometriosis are infertile. ARID1A protein levels were significantly lower in the eutopic endometrium of women with endometriosis compared to women wi...

It has previously been shown that granulated metrial gland (GMG) cells of the pregnant uterus express abundant quantities of the lymphocyte pore-forming protein, perforin. No perforin was present before implantation of the embryo, but large numbers of perforin-producing GMG cells were observed after implantation, which coincides with decidualization of the uterus. The possible source of the act...

introduction: we investigated the role of atp-sensitive potassium channels and l-type calcium channels in morphine-induced hyperalgesia after nociceptive sensitization. methods: we used a hotplate apparatus to assess pain behavior in male nmri mice. nociceptive sensitization was induced by three days injection of morphine and five days of drug free. on day 9 of the schedule, pain behavior test ...

since the uterine is a sensitive tissue to steroid hormones, the aim of the present study was to investigate the effects of 17β-estradiol (e2) and progesterone (p4) alone or in combination on morphological and morphometrically parameters of ovariectomized mouse uterus.adult virgin female mice (8-10 weeks old)were ovariectomized and treated with e2, p4, e2 followed by p4 and the oil vehicle alon...

Endometrial carcinoma is the most common gynecologic cancer, yet the mechanisms underlying this disease process are poorly understood. We hypothesized that Lef1 is required for endometrial gland formation within the uterus and is overexpressed in endometrial cancer. Using Lef1 knockout (KO) mice, we compared uterine gland development to wild-type (WT) controls, with respect to both morphology a...

BACKGROUND Livestock that consume locoweed exhibit multiple neurological symptoms, including dispirited behavior, staggered gait, trembling, ataxia, impaired reproductive function and cellular vacuolar degeneration of multiple tissues due to toxicity from plant-derived alkaloids such as swainsonine. RESULTS Swainsonine was administered to F(0) and F(1) mice by intraperitoneal injection before...

Endometriosis is the condition where endometrium gets implanted and flourishes outside the uterine cavity, most commonly in ovary and on the peritoneum which lines the abdominal cavity and viscera. Endometrial cells in areas outside the uterus are influenced by hormonal changes and respond in a way similar to the endometrium inside the uterus. Symptoms often worsen with the menstrual cycle. We ...

Follicular hormone under physiological conditions produced hyperplasia of the muscular wall and proliferation of the mucous membrane of the uterus of rabbits. The following pathological changes were brought about by prolonged application of large doses of the hormone: (a) hyperaemia of the myometrium and the endometrium, with occasional scanty extravasal haemorrhages; (b) glandular-cystic hyper...

      The effects of hydroalcoholic extract of Peganum harmala seeds (EPS) on spontaneous rhythmic contractions of isolated rat uterine was investigated in this study. EPS was tested on the isolated uterus and endometrium free (i.e. stripped myometrium) preparations. EPS was found to exhibit significant spontaneous contractions of the uterus and stripped myometrium relative to the solv...
