Haemagglutination reaction in Indian childhood cirrhosis indicating viral aetiology.

tests which assess distal tubular function (Broberger Winberg, and Zetterstrom, 1960). The disorder may appear at different ages and have variable rates of progression, even within the same family, but it usually takes a rapid course in childhood, while a more protracted course is common in adults (Axelsson and Odlund, 1968). The aetiology of nephronophthisis is obscure. Bacterial infection is not considered to play a role in its pathogenesis. It has been postulated (Mongeau and Worthen, 1967) that the tubular damage might be caused by a 'toxin' resulting from an inborn metabolic error.
