[Examining consecutively serum leptin levels in normal pregnant and pregnancy-induced hypertension women].

Objective: To detect successsively serum leptin levels in normal, pregnancy-induced hypertension (PIH) pregnant women.

Methods: Levels of serum leptin were measured in the 16-20, 24-28, 32-36 weeks of gestation, at the delivery time in 50 healthy, 14 PIH pregnant women and their newborns and in 40 healthy non-pregnant women by Immuno-radioassay method. Serum leptin levels were correlated with body weight, body mass index (BMI), blood pressure and placental weight.

Serum leptin levels of menopausal women before and after hormone replacement therapy.

Objective: To measure serum leptin levels of menopausal women before and after hormone replacement therapy, and to evaluate the action of hormone replacement therapy in regulating serum leptin levels.

Methods: Serum leptin levels of 27 menopausal women were measured before and after hormone replacement therapy by double-antibody enzyme-linked immunosorbent assay (ELISA) and compared with those measured in 35 women with regular menstrual cycle.

Results: Compared with normal control (17.
