[Comparison of the effects of orally or percutaneously administered estradiol on carbohydrates and lipids after the menopause].

The metabolic changes in carbohydrate (fasting blood sugar and blood sugar levels two hours after taking 70 g of glucose orally as well as insulin and glycosylated A1c haemoglobin) and also lipid metabolism as total and fractional HDL, triglycerides and alphaprotein B, were compared in 43 patients of a mean age of 48.6 years who had hysterectomy with castration. These patients were divided into two random groups: the first group (23 women) received hormone replacement treatment in a dose of 1.

["In vitro" glass fiber filtration of sperm (author's transl)].

Filtering sperm through glass fiber has been suggested as a method for improving its fecundity before homologous artificial insemination. Various technical modification of this procedure have enabled good results to be obtained on spermatozoid mobility but at the expense of a marked drop in numbers: sperm counts per ml are diminished by a half. A comparative in vitro study of the penetration of filtered and non-filtered sperm into the cervical mucus showed that glass fiber filtration produced generally no great improvement, and may indeed reduce penetration into the cervical mucus to a marked degree in some cases.
