Human mast cells (MCs) are long-lived tissue-resident immune Background: cells characterised by granules containing the proteases chymase and/or tryptase. Their phenotype is modulated by their tissue microenvironment. The human uterus has an outer muscular layer (the myometrium) surrounding the endometrium, both of which play an important role in supporting a pregnancy. The endometrium is a sex...

Menstruation-associated disorders negatively interfere with the quality of life of many women. However, mechanisms underlying pathogenesis of menstrual disorders remain poorly investigated up to date. Among others, this is based on a lack of appropriate pre-clinical animal models. We here employ a mouse menstruation model induced by priming mice with gonadal hormones and application of a physic...
The postpartum uterus involutes to its pre-pregnant and fully functional state within approximately 60 d after calving. Uterine glands are essential for fertility but little is known about their regeneration postpartum. Likewise, the effect of uterine disease (metritis) on gland unknown. We hypothesized that would be regenerated early metritis associated with slower affect numbers later during ...
BACKGROUND Aging contains morphological and functional deterioration in biological systems. D-galactose (D-gal) generates free radicals and accelerates aging. Portulaca oleracea (Purslane) may have protective effect against oxidative stress. OBJECTIVE Purslane ethanolic extract effects were evaluated on antioxidant indices and sex hormone in D-gal aging female mice. MATERIALS AND METHODS 48...
It is clear from studies using progesterone receptor (PGR) mutant mice that not all of the actions of progesterone (P4) are mediated by this receptor. Indeed, many rapid, non-classical P4 actions have been reported throughout the female reproductive tract. Progesterone treatment of Pgr null mice results in behavioral changes and in differential regulation of genes in the endometrium. Progestero...
The goal of this study was to evaluate the effects of quercetin and ACTH injection on prevention of development of morphine tolerance and dependence in mice. In this study different groups of mice received morphine (40 mg/kg, i.p.) plus quercetin (5, 10, 25 mg/kg, ip), ACTH (1, 2.5, 5 IU/mice, i.p.), or combination of quercetin (5 mg/kg) and ACTH (1 IU/mice) once a day for four days. Toler...
mice were rendered tolerant and dependent to morphine by subcutaneous injection of morphine over a period of 5 days. the effects of acute and chronic administration of dihydropyridine calcium channel antagonist nifedipine on the development of tolerance and naloxone-precipitated morphine withdrawal signs were investigated. a single injection of nifedipine proved to be effective in inhibiting so...
A survey of the expression of the multidrug-resistance gene (mdr) in mouse tissues revealed that a mdr mRNA species is expressed at extremely high levels in the gravid uterus. mdr mRNA expression levels increase dramatically during pregnancy compared to the relatively low levels of expression observed in the nongravid uterus. In situ hybridization experiments revealed that the increased express...
in this study, we investigated the interactive effects of intraperitoneal (i.p.) injections of three different phosphodiesterase inhibitors (pdeis) on morphine-induced analgesia in mice using tail-flick method. subcutaneous administration of morphine (1, 3 and 6 mg/kg) caused significant antinociceptive effects in a dose dependent manner. administration of pentoxifylline (12.5, 25, 50 and 100 m...
