INTRODUCTION Transvaginal sonography and human chorionic gonadotropin (hCG) testing are cornerstones of modern clinical practice in cases with the suspected ectopic pregnancy. In unclear cases, if the level of hCG is above the discriminatory zones, the use of uterine curettage is recommended.There is an increasing concern that strict observation of the guidelines would potentially harm otherwis...

different opinions exit in histological typing of bone cysts. epidermoid cysts are very rare as the small numbers of published cases indicate. they arises following preceding trauma exclusively in distal phalanges and skull. the roentgenogram shows a round osteolytic resion with no trabecular pattern. we observed 2 cases of epidermoid cyst of finger in imam khomeini hospital central path depart...

An intestinal preparation from the common eel (Anguilla anguilla) was characterized for both mucosal to serosal and serosal to mucosal transport of water, alanine, sodium and chloride. The preparation showed a net outflux of water and a net influx of alanine, and no net fluxes of sodium or chloride. The influxes of all four substances and the outflux of water were inhibited by ouabain, while th...

Model and real biles were used to investigate factors influencing cholesterol and dextran (70,000 molecular weight) absorption by the gall bladder. Cholesterol absorption was proportional to cholesterol concentration when real bile was used, but model biles showed maximal absorption at cholesterol saturation. Reduction of temperature reduced cholesterol absorption and serosal secretion, but had...

fibroids are the most common benign tumors of the uterus during female reproductive age. uterine artery embolization (uae) using embolic particles (pva, gelfoam) to occlude the uterine arteries, have been reported as a relatively safe, effective, and durable nonsurgical alternative to hysterectomy in diminishing fibroid-related symptoms. to block the arterial blood supply to the fibroid complet...

ndometrial vasculature has been shown to play an important role in the early endometrial response to the implanting blastocyst, and vascular changes may contribute to uterine receptivity . the aim of this study was to investigate the role of endometrial and subendometrial vascularity and thickness in uterine receptivity in infertile women treated with assisted reproductive technologies (art). a...

The rats were fasted overnight and then anesthetized with pentobarbiturate. Segments of the duodenum, jejunum, ileum, and colon of 6 cm length were isolated. Each specimen was everted to prepare a sac with mucosa on the outside. Each gut sac was filled with 600μl of multitracer solution and then immersed in 10ml of the buffer solution and incubated with bubbling 95% O2 and 5% CO2 at 37 ◦C for 9...

Pancreatic duct epithelial cells (PDEC) mediate the secretion of fluid and electrolytes and are exposed to refluxed bile. In nontransformed cultured dog PDEC, which express many ion transport pathways of PDEC, 1 mM taurodeoxycholic acid (TDCA) stimulated an (125)I(-) efflux inhibited by DIDS and 5-nitro-2-(3-phenylpropylamino)benzoic acid (NPPB) and a (86)Rb(+) efflux inhibited by charybdotoxin...

The effect of the short duration (21 days) of caffeine at two different doses (12 mg & 30 mg/kg body weight/day) on the activities of adenosine triphosphatases in jejunum was studied. The activity of Na+, K+ -dependent ATP-ase was reduced significantly in the upper jejunal mucosal and serosal layers of low an high dose groups. Such effect was observed only in the lower jejunal serosal layer whi...
