[ABO blood groups in patients with nephropathies].

280 patients of a centre of nephrology were with regard to their distribution of ABO and rhesus blood groups compared with a control group consisting of 4,089 donors. Female patients with pyelonephritis showed with a probability of error of less than 5% more frequently the blood group A (56.7 vs 41.

[Physiological influences on the enzyme elimination with urine].

It is desirable to know the factors determining the large interindividual and interindividual variation of urinary enzyme excretion rates among normal individuals to allow a better understanding of pathological states. The following factors seems to play a significant role in influencing total enzyme efflux rates: urinary flow, age, sex, biorhythms, genetic factors, hormonal situation (including pregnancy), nutrition, and physical activity.
