RÉSUMÉ
Treadmill exercise test was performed in 100 patients, 50 were hypertensive who were not having any clinical or electrocardiographic manifestation of coronary artery disease and 50 were controls. The test was positive in 28% of hypertensive patients as compared to 6% in controls. This study therefore suggests that hypertension is frequently associated with asymptomatic coronary artery disease as compared to normotension and it is concluded that exercise electrocardiography test is a definite diagnostic tool in diagnosis of coronary artery disease not only in symptomatic but also in asymptomatic patients with one or more risk factors.

Twenty five children suffering from minimal change nephrotic syndrome were studied for immunological alterations at different stages of this disease i.e., onset, relapse and remission. Changes were found mainly at onset and during relapse in the form of altered helper and suppressor cell ratio, depressed delayed cutaneous hypersensitivity reaction, decreased S-IgG bearing lymphocytes with low serum IgG concentration, and increased S-IgM bearing lymphocytes with high serum IgM concentration. Majority of these parameters returned to normal values during remission. Serum IgE was found high at all stages of this. These alterations suggest defects in cell mediated immunity resulting in secretion of some substance which modifies the glomerular anionic charges.

Fifteen patients of acute intermittent porphyria (AIP) were detected out of 2500 persons of Maheshwari community surveyed. These 15 patients belonged to 11 families. The prevalence of AIP in Maheshwari population came out to be 1:640 which is considerably higher than the figures reported from many other areas of our country. AIP was more common in females than males, the ratio being 9:6. Maximum number of cases (6) were encountered in the age group of 11-20 years. AIP was observed to be inherited as an autosomal dominant disease in 3 families. Spontaneous mutation of gene may be considered to be the mode of inheritance in the remaining 8 families. The disease was found to be more common in Daga and Tapadia subcastes. There were 5 cases belonging to Daga subcaste and 3 belonging to Tapadia subcaste.
