This case report describes the first attempt to treat imminent ovarian hyperstimulation syndrome (OHSS) by using a gonadotrophin-releasing hormone (GnRH) antagonist. A 33 year old, normo-ovulatory woman undergoing in-vitro fertilization received daily subcutaneous injections of 150 IU of recombinant follicle-stimulating hormone (recFSH) from cycle day 2, together with GnRH antagonist (ganirelix...

Embryos produced in an in-vitro fertilization (IVF) programme, but which were unsuitable for transfer to patients because they originated from one (1PN) or three pronuclear (3PN) oocytes or because they originated from two pronuclear (2PN) oocytes but cleaved normally, were maintained in tissue culture. The embryos that progressed to blastocytes were cultured to day 14 of development in order t...

It has been shown that either adrenocorticotrophic hormone (ACTH) or the 11-oxygenated adrenal cortical steroids inhibit the hyaluronidaseenhanced spreading phenomenon in the rabbit and in the mouse.q 8 In view of the favorable influence of pregnancy on certain of the collagen diseases, it was of interest to determine whether chorionic gonadotrophin had any influence on this phenomenon. This wa...

Given its rustic nature, its butchery quality and its trypanotolerance, the N’Dama breed represents a significant potential for developing African cattle breeding [6]. To date, its zootechnical performance and reproductive characteristics have been the subject of relatively little work. The use of selection programmes and artificial insemination are highly significant challenges for developing ...

Preoperative pregnancy testing is common practice among anesthesiologists. Little is re-ported in anesthesia literature on causes other than pregnancy for elevated human chorionic go-nadotrophin (hCG) levels. Among these causes is hCG secretion by tumors. This is a report of a female with pancreatic cancer that presented for a Whipple procedure, who on routine pregnancy testing was found to hav...

An experiment was conducted to determine whether gonadotrophin-releasing hormone (Gn-RH) or HCG would reduce the proportion of unruptured follicles in the Galway ewe following a high superovulating dose of PMSG given in conjunction with a progestagen to synchronize oestrus. Forty-four Galway ewes aged 1\m=1/2\to 5 years (average wt 64\m=.\7kg) were treated with intravaginal pessaries impregnate...

The current work aimed to study the effect of preeclampsia on maternal serum level of beta subunit of human chorionic gonadotropin and maternal plasma level of adenosine deaminase. Ninety pregnant women with gestational age 24 26 weeks were selected for this study, they were classified into three groups: group 1 consists of 30 women with normal pregnancy, group 2 consists of 30 patients with mi...

Chemotherapy, in conjunction with other methods of treatment, was used in 100 patients with invasive hydatidiform mole or choriocarcinoma following mole. When treatment was instituted within two to six months of the antecedent mole serious drug resistance was not encountered, drug toxicity was slight, the duration of treatment was comparatively short, and sustained remissions were obtained in 5...
