Electromagnetic field in and around the campus of Jawaharlal Nehru University, New Delhi.

We have surveyed the levels of magnetic field in the open environment around the high-tension lines as well as in the domestic and laboratory environment in the JNU campus. Measurements were made in the direction of most likely access, and from the surface of the appliances. The data so obtained are analyzed and compared with some quoted in the literature. It is hoped that the results will be useful for epidemiological studies in determining the criteria for safe human exposure.

Intra pulmonary thrombolytic therapy with balloon dilatation in recurrent acute pulmonary embolism.

A 52-year-old man had recurrent pulmonary thrombo embolism following fracture in tibia and subsequent deep vein thrombosis. One episode of massive pulmonary embolism with haemodynamic compromise was managed successfully by balloon compression of the thrombus and thrombolysis with urokinase. Patient was rehabilitated in his previous profession.

Renal dysfunction in enteric fever.

Twenty-five culture positive cases of enteric fever were studied to see the effect of the disease on various kidney functions. The parameters studied were urine examination, blood urea, serum creatinine, serum electrolytes, 24 hours urinary examination (proteins, creatinine, electrolytes), creatinine clearance rate, plain X-ray abdomen, intravenous urogram and circulating immune complexes. Fifteen patients with fever of non-specific origin served as controls. Renal dysfunction was observed in four patients (16%). Repeat tests showed that abnormalities of renal functions, though significant, were short lasting and reversible. Renal biopsy done in three of these cases did not reveal any abnormality.
