ABSTRACT
Fifty healthy subjects underwent incremental exercise on a treadmill. Anaerobic threshold (AT) and maximum oxygen consumed in litres per minute (VO2 max) were measured. VO2 max (mean +/- SD) in males and females was 2.71 +/- 0.5 and 2.014 +/- 0.4 L/min respectively. AT as a percentage of VO2 max predicted was 58 in males and 56 in females. These values were comparable to Western studies. Anaerobic threshold is the most sensitive indicator of exercise performance.

Serum angiotensin converting enzyme (SACE) was estimated in 25 normal healthy subjects mean (15.62 +/- 6.5 mU/mL/37 degrees C), 26 patients with sarcoidosis (32.06 +/- 9.7) 15 with pulmonary tuberculosis (16.31 +/- 4.6) and 19 with diffuse interstitial lung disease (11.72 +/- 4.555). Significantly (P less than 0.05) elevated SACE values were seen in active sarcoidosis, and serial SACE levels correlated well with the course of the disease.
