RESEARCH DESIGN AND METHODS The study was conducted among Malays and Orang Asli in six rural and urban locations in Malaysia. OGTTs were performed on(More)
In this study we examined the incidence of hypercalcaemia among patients with tuberculosis in Malaysia. Serum calcium concentration and other calcium metabolism parameters were studied in 43 newly diagnosed tuberculous patients from the Kuala Lumpur General Hospital and the National Tuberculosis Centre. Forty-four patients admitted to the medical wards of(More)
In an attempt to track the proliferation/demise of trophoblastic tissues in women following gamete transfer (GT) or in vitro fertilization/embryo transfer (IVF/ET), we have measured levels of human chorionic gonadotropin (hCG) in serum of 180 patients on days 7 and 14 following oocyte pickup (OPU). Serum hCG levels were measured by immunoassay and by a(More)
The effect of thyroid hormones on the renin-angiotensin-aldosterone system has not been fully resolved. Highly specific immunoassays for measurement of renin, aldosterone, free T4 (fT4), free T3 (fT3) and ultrasensitive TSH enables a direct and more accurate measurement of these hormones. We investigated the relationship between plasma renin, aldosterone(More)
Thyroid function and pubertal development of aborigines (Orang Asli) and Malays at different socioeconomic strata were assessed among 1136 subjects aged 7 years and above. Anthropometric measurements, goitre and pubertal staging were done. Serum thyroxine (T4), triiodothyronine (T3) and growth hormone were measured using radioimmunoassays (RIA) and serum(More)
Thirty-eight normal volunteers and 10 patients with untreated thyrotoxicosis were each given 0.5 ml of Lugol's solution daily for 10 days. On days 0, 5, 10, 15 and 20, serum levels of T4, free T4, T3 and TSH (by sensitive immunoradiometric assay) were measured. In normal subjects, the serum concentrations of free T4 declined significantly at day 10 while(More)
The relationship between malnutrition, goitre and thyroid hormones was studied among Aborigines and Malays in Ulu Langat, Malaysia. Fifty Aborigines aged >=7years were selected randomly for anthropometric, clinical and hormonal assessment. Fifty Malays of similar age from the nearby Malay village were chosen as controls. The Aborigines had a higher(More)
Twelve cases of primary hyperparathyroidism operated by the Universiti Kebangsaan Malaysia Surgical Team from 1978 to 1989 were reviewed. There was a preponderance of Indian females in this series. The majority of the cases presented late and with complications. Renal calculi and bone disease were the commonest complications noted. Of the 12 patients, 9 had(More)
