Mammalian embryonic diapause is a phenomenon defined by the temporary arrest in blastocyst growth and metabolic activity within the uterus which synchronously becomes quiescent to blastocyst activation and implantation. This reproductive strategy temporally uncouples conception from parturition until environmental or maternal conditions are favourable for the survival of the mother and newborn....

A kinetic procedure, based on differences in affinity of lactate dehydrogenase (LDH) subunits for L(+)-lactate, was employed to measure the M and H subunit activities of this enzyme in a variety of normal and neoplastic tissues of the rat. Total LDH activity was highest in liver (both normal and regenerating) at about 150 units per gm fresh tissue and somewhat lower in heart and femoral muscle ...

S uccessful pregnancy requires a series of coordinated interactions between the developing placenta, the uterus, and the maternal immune system (1). At the maternal/fetal interface, where the placenta contacts the uterus, a specialized type of lymphocyte known as a uterine natural killer (uNK) cell is thought to play a critical role in mediating the uterine vascular adaptations to pregnancy. Ep...

Future fertility is of paramount importance to younger cancer survivors. Advances in assisted reproductive technology mean that young women treated with radiation involving the uterus may require clinical guidance regarding whether to attempt a pregnancy themselves. We performed a review of the literature regarding radiation involving uterus (total body irradiation (TBI) and pelvic radiation), ...

      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...

abstract bicornuate uterus is class iv and septate uterus is class vin uterine anomaly classification. bicornuate uterus is almost always treated by laparotomy and metroplasty. but the treatment of choice for septate uterus is hysteroscopic metroplasty. bicornuate- septate uterus which is described in this paper is a new class of uterine anomaly(between class iv & v). the advantages of hysteros...

The endogenous cannabinoid (eCB) system is emerging as an important component of female reproductive tract physiology. The eCBs anandamide (AEA), 2arachidonoyl glycerol (2-AG), and N-arachidonoyl glycine (NAGly) were measured in the rat reproductive tract at five time points in the four-day estrous cycle, in acyclic retired breeders (RB), after ovariectomy (OVX), OVX + estrogen (E2), OVX + prog...

Connexin (CX) proteins participate in growth, differentiation, and tissue remodeling. Relaxin-stimulated reproductive tissue growth and remodeling may be facilitated by enhanced intracellular communication. This study was an examination of the effects of relaxin in vivo on expression of CX-26, CX-32, and CX-43 in the cervix and uterus of prepubertal pigs. In addition, expression of these protei...

background: cassia italica or senna is a wild plant distributed in south of iran. it increased water consumption and has a laxative effect. in traditional medicine this plant has been used for the dysmenorrheal. objective: in this study we investigated the effect of aqueous extract of cassia italica on uterus contraction. materials and methods: virgin wistar rats 200-300g were purchased. after ...

congenital mullerian abnormalities, particularly the septate uterus, may result in recurrent abortion, premature labor and infertility. the purpose of this study is to report the surgical and reproductive outcome in two groups of patients who underwent hysteroscopic metroplasty (hmp). between aug. 1993 and march 1998,76 women underwent hmp in shiraz university of medical sciences' affiliat...
