Human oviductal fluid proteins.

The popularity of mini-laparotomy provided an opportunity to easily collect human oviductal fluid (HOF). Volumes of HOF produced by two oviducts per 24 hours correlated positively with serum estradiol determinations, while protein concentration in HOF was inversely proportional to estrogen levels. Estrogen appeared to stimulate the production of oviductal fluid in women. The greatest volumes of HOF were observed at midcycle, coincident with the estrogen peak. Protein concentration was lowest at the time of ovulation and highest immediately before and after menstruation. In a large percentage of patients, certain proteins made their appearance at the time of ovulation and receded or disappeared within three to five days thereafter. By electrophoresis, these proteins were seen in the albumin region and in the beta globulin region.

Extracorporeal perfusion of the whole human placenta--a new model.

An extracorporeal dual perfusion system of the whole human placenta was developed using a technique of multiple blunt cannulations of the intervillous space. The system was evaluated according to various perfusion-dynamic, metabolic and morphological criteria. Angiographic and dye distribution studies showed 80 to 100 per cent perfusion of the placenta. The perfused organ consumed oxygen, utilized glucose and produced HCG. The flow rates and acid-base values were within acceptable limits. However, problems with high fetoplacental vascular resistance, tendency to metabolic acidosis and fetomaternal fluid transfer were encountered. Ultrastructural studies showed variations in the syncytiotrophoblast and the microvilli.

Complications of laparoscopic tubal sterilization.

The experience of laparoscopic sterilization in 5018 cases at the Deaconess Division of Buffalo General Hospital over a period of 8.5 years is presented. The procedure was completed in 4992 cases, with a complication rate of less than 1% and with no operative mortality. One half of the patients with complications required a laparotomy. Bleeding was the most common complication; it accounted for exactly one half the complications. The laparotomy rate for all complications was 4.6 per 1000 cases. Seven ectopic and 4 intrauterine pregnancies occurred after this procedure, for a method failure rate of 2.2 per 1000 cases. Recommendations for prevention and management of complications are presented.
