Adipose tissue lipolysis and lipoprotein lipase (LPL) activity were studied in biopsies from the femoral and abdominal depots in healthy women during early or late menstrual cycle, pregnancy, and the lactation period.When the differences in cell size were taken into account, basal lipolysis was similar in both regions in nonpregnant women. During lactation, however, lipolysis was significantly higher in the femoral region. The lipolytic effect of noradrenaline (10-' M) was significantly less in the femoral region in the nonpregnant women and during early pregnancy. However, the lipolytic response was the same in both regions in lactating women. LPL activity was higher in the femoral than in the abdominal region except during lactation when a marked decrease in the LPL activity was seen in the femoral region. The LPL activity in the abdominal region remained unchanged in all patient groups.The results imply that in both nonpregnant and pregnant women lipid assimilation is favored in the femoral depot. During lactation, however, the metabolic pattern changes; the LPL activity decreases and lipid mobilization increases in this depot. These changes are much less pronounced in the abdominal region. Thus, fat cells from different regions show a differential response during pregnancy and lactation. These results suggest that the adipose tissue in different regions may have specialized functions.

Restorative proctocolectomy with an ileal pouch-anal anastomosis preserves anal sphincters, the normal route of defaecation and the normal body image and it has been suggested that the procedure might be associated with less gynaecological and sexual problems than conventional proctocolectomy. To shed further light on this subject 60 female patients were invited to participate in a study comprising a detailed interview, examination by a gynaecologist and investigation with hysterosalpingography and vaginography. Twenty-one women with a mean follow-up of 38 months after surgery agreed to participate. Their gynaecological state was considered normal although one woman complained of vaginal discharge. Five women experienced occasional dyspareunia and 2 patients had to take special precautions to avoid bowel leaks at intercourse. While the position of the vagina and uterus in the pelvis appeared normal, hysterosalpingography disclosed bilateral occlusion of the fallopian tubes in 2 and unilateral occlusion in another 9 patients with tubes adhering to the bottom of the lesser pelvis in 10 of the patients. Only one out of 14 patients succeeded in trying to conceive during the follow-up period. Among the remaining 39 women not specially studied 5 out of 14 had conceived after the operation.

In order to evaluate the effect of exogenous sex steroids on adipose tissue metabolism, two groups of postmenopausal women were studied. In one of the groups, the effect of 50 micrograms ethinyl estradiol (EE) was investigated given orally alone and in combination with 10 mg norethisterone acetate (NET). This combination is reminiscent of an old high dose oral contraceptive. In the other group, the effect of 3 mg 17 beta-estradiol was evaluated when administered percutaneously alone and in combination with 300 mg micronized progesterone given orally. These substances and doses were chosen to provide a "physiological" hormonal influence. In the femoral region 50 micrograms EE induced an increase in LPL activity. This elevated LPL value was reversed with the addition of 10 mg NET. Moreover, during treatment with 50 micrograms EE, a decrease in norepinephrine stimulated lipolysis was seen in the abdominal region. The percutaneous administration of 17 beta-estradiol with or without micronized progesterone, however, was inert as regards subcutaneous adipose tissue metabolism. Our findings indicate, therefore, that EE in doses used in oral contraception might promote lipid accumulation in the femoral adipose tissue depot.
