In vitro fertilisation in a small unit in the NHS.

In vitro fertilisation is one of the most effective new treatments for infertility, but financial restrictions have made it impossible for it to be widely carried out in the National Health Service. We report on the establishment of a small, largely self funded, unit that was set up with the help of the local health service management. All cycles are programmed so that most work is carried out during the working week; oocyte recoveries are performed as outpatient procedures without general anaesthesia and guided by ultrasound. Roughly a tenth of treatment cycles and roughly a fifth of embryo transfers resulted in a clinical pregnancy.

Binding of tritiated yohimbine to platelets in women with maternity blues.

Platelet alpha 2-adrenoceptor binding was measured in 108 women in the 36th week of pregnancy, at ten and twenty days and at three and six months post-partum. An age matched non-pregnant control group of women (N = 25) was also studied. The number (Bmax) of alpha 2-adrenoceptors was elevated antepartum but fell to control values on the tenth post-partum day. At three and six months post-partum, however, alpha 2-adrenoceptor Bmax was again increased. Women who developed maternity blues (N = 59) had significantly more platelet alpha 2-adrenoceptors than those who did not (N = 49) at both ten and twenty days post-partum. In addition their alpha 2-adrenoceptor Bmax was greater than controls at all time points measured except the tenth post-partum day. In contrast, the alpha 2-adrenoceptor Bmax of women without the blues did not differ from controls at any stage. It is suggested that women who develop maternity blues may have a relatively enduring abnormality in alpha 2-adrenoceptor sensitivity which is associated with psychological symptoms when concentrations of circulating sex-steroids suddenly change.

Differentiated mouse epithelial cell line with hepatocyte characteristics.

An epithelial cell line, 3105, with an unusual growth pattern has been derived from the liver of an (NZB x NZW)F1 mouse. When confluent, it forms a monolayer of closely packed cells interspersed with holes that do not fill in during cultivation. By electron microscopy, the line has tight and intermediate junctions as well as desmosomes typical of epithelial cells. It produces several enzymes normally present in liver including hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase, glucose-6-phosphatase, and alkaline phosphatase; has cytochromes P-450 and b5; and spontaneously release xenotropic but not ecotropic endogenous mouse type C viruses. Inoculation of the cell line into athymic nude mice gives rise to benign cysts in 2-3 months. This mouse epithelial line with hepatocyte characteristics should be helpful to investigators as a cell model of normal liver cell differentiation.
