This experiment investigated the effects of three types of structured exercise (aerobics, bodybuilding, and circuit training) on depressive symptoms of 45 clients undergoing a 4-wk., inpatient rehabilitation program for substance abuse. Pre- and posttest measures included the Center of Epidemiological Studies--Depression, resting pulse rate, blood pressure, maximum strength on incline bench press, and estimates of aerobic fitness and body fat. The bodybuilding program produced a significant decrease in depressive symptoms. Physiological and psychological explanations are discussed.

Mycobacterium kansasii was thought to exist primarily as a saprophyte until two cases of clinical infection were reported by Buhler and Pollak in 1953 On examination his temperature was 38-3°C, pulse rate 100/min, blood pressure 118/66 mm Hg, and respiratory rate 20/min. The patient was alert and not in any acute distress. There was a loud biphasic pericardial friction rub, which seemed to intensify with deep respiration. There were no gallops or murmurs. There was no pulsus paradoxus and the jugular venous pressure was normal. Breath sounds were decreased at the left lower base. The liver was slightly enlarged. Investigations showed: haemoglobin concentration 7 1 g/100 dl; packed cell volume 0*24; white blood cell count 7-3 x 109/l (83% polymorphonuclear leucocytes, 14% lymphocytes, 3% monocytes. The blood urea nitrogen concentration was 17 mg/dl. Arterial oxygen and carbon dioxide tensions during the breathing of room air were: Pao2 60 mm Hg (8 kPa), Paco2 29 mm Hg (3-87 kPa); the pH was 7 56. The serum albumin concentration was 29 g/l. The erythrocyte sedimentation rate was 39 mm in one hour. Urine analysis showed: protein 0-3 g/l, 6-10 white blood cells per high power field, and a few hyaline and many granular casts. The chest radiograph showed a moderately enlarged heart and blunting of both costophrenic angles. Two dimensional echocardiography showed pericardial fluid with normal left ventricular function. Sputum was examined for acid fast bacilli and cultures of Mycobacterium tuberculosis were initiated. Three blood cultures yielded no growth.
