Quantitative ultrasound (QUS) is emerging as a simple, inexpensive and noninvasive method for assessing bone quality and assessing fracture risk. We assessed the usefulness of a contact calcaneal ultrasonometer by studying normal premenopausal women (group I, n = 53), normal postmenopausal women (group II, n = 198), and osteoporotic women without (group(More)
Tests for a range of autoantibodies, and counts of lymphocytes, B cells, T cells, and T cell subsets were performed in 45 Chinese patients with premature ovarian failure and 45 age-matched normal control subjects. Eight patients (18%) were positive for at least one autoantibody. Only one patient was positive for antiovarian antibody. Patients with(More)
Chinese factory workers (427) mainly of Fujian origin were found to have few climacteric symptoms. Of these, 65% and 50% reported having no circulatory and nervosity symptoms, respectively. Only 18% of women experienced hot flushes. The climacteric symptoms were more pronounced at the perimenopausal period (P < 0.001) when these women experienced more(More)
Cross-sectional studies on the effects of depot-medroxyprogesterone acetate (DMPA) on bone mineral density (BMD) have been controversial. The present longitudinal cohort study on 59 Chinese women over a period of 3 years has shown that their annual rate of bone loss at 3 sites (0.44% in lumbar spine, 0.40% in neck of femur, 1.05% in Ward's triangle) was(More)
In a randomized, double-blind study, the antiemetic efficacy of a single bolus of tropisetron 5 mg (group T, 37 patients), ondansetron 4 mg (group O, 39 patients) or saline (group C, 45 patients) given at induction was compared in a homogeneous group of 121 patients undergoing gynaecological laparotomy and receiving postoperative patient-controlled(More)
We have previously demonstrated that in patients with oestrogen deficiency, there was a significant reduction in the ratio of CD4+ to CD8+ lymphocytes. To test our hypothesis that oestrogen deficiency was the cause of the changes in lymphocyte subsets, we have studied the lymphocyte subsets and serum immunoglobulin levels in 35 patients with idiopathic(More)
Ten Chinese women who had menorrhagia without organic cause and suffered from anaemia were treated with levonorgestrel intrauterine device for a total of 129 woman-months. There was a 54%, 87% and 95% reduction in menstrual blood loss at the first, third and sixth month of treatment when compared with the pretreatment cycle. These percentages of reduction(More)
Men with the spermatological symptom of polyzoospermia (greater than 250 X 10(6) sperm/ml) have been reported to seldom impregnate their wives. It was the aim of this study to investigate the spermatozoal fertilizing capacity in polyzoospermia by the human sperm and zona-free hamster ova penetration bioassay. General semen characteristics and in vitro(More)
We have previously shown that in patients with idiopathic premature ovarian failure there were significant changes in lymphocyte subsets. To test our hypothesis that these changes were due to oestrogen deficiency we studied lymphocyte subsets in patients with oestrogen deficiency due to other causes. Blood was taken for serum oestradiol, lymphocyte counts(More)
The association between long-term use of depot-medroxyprogesterone acetate (DMPA) and bone mineral density (BMD) has been controversial, as seen in three case-control studies in New Zealand, Thailand, and the United Kingdom. In the present case-controlled study of BMD, a group of 67 Chinese women who had used DMPA from 5-15 years was compared with 218 women(More)
