BACKGROUND This report presents updated National Academy of Clinical Biochemistry Laboratory Medicine Practice Guidelines summarizing quality requirements for the use of tumor markers. METHODS One subcommittee developed guidelines for analytical quality relevant to serum and tissue-based tumor markers in current clinical practice. Two other subcommittees(More)
1. Anthropometric variables, resting heart rate and respiratory gas exchange were measured in twelve male and nine female Asiatic adult Moslems during the month of Ramadan, the week before and the month after Ramadan. 2. Energy intakes were estimated from dietary recall during fasting and non-fasting conditions. 3. Both male and female subjects experienced(More)
Urine analysis was conducted on male Muslims before, during and after Ramadan. Various changes in urine volume, osmolality, total solute, sodium, potassium, titratable acidity and urea in response to altered feeding and activity regimens were found. There were no detectable levels of ketones, protein, glucose, urobilinogen and haemoglobin. It was concluded(More)
We report a previously undocumented drug interaction between cyclosporine A and quinine. A 39 year old Asian with a recent renal transplant was diagnosed to have a mild cerebral falciparum malaria. He was treated with seven days of oral quinine (600 mg, 8 hourly), followed by a stat dose of pyrimethamine (75 mg)--sulfadoxime (1200mg) because of a strong(More)
The effect of alteration of eating pattern during Ramadan on body mass index (BMI), serum fructosamine: total protein ratio (F/TP), and glucose level in 18 healthy male Asiatic Moslems were studied. The results showed a significant decrease (p less than 0.025) in F/TP at the second week of Ramadan in 11 subjects who experienced continuous decrease in BMI(More)
Of 36 cases of choriocarcinoma treated at the University Hospital Kuala Lumpur during 1980-84 inclusive, 6 patients were found to have cerebral metastases. Intrathecal methotrexate and combination chemotherapy were started in all cases, with monitoring of tumor growth by serial beta-HCG assays and CT scanning of brain and lung. Chemotherapy was reduced(More)
A simple and convenient method of transport of serum in the form of protein disc on water resistant medium is described. The method was used to study the stability of thyroxine (T4), cortisol, thyroid stimulating hormone (TSH), parathormone (PTH) and insulin. The mean recoveries of these hormones were between 98 and 100%. The standard deviations of(More)
