Persons participating in a 5-day diagnostic protocol were routinely typed for ABO, Rh, MNS, Kell, Kidd, Duffy, P, Haptoglobin, phosphoglucomutase-1 (PGM-1), and acid phosphatase (AcP). The study population was composed of 164 normotensive whites, 34 normotensive blacks, 161 whites and 43 blacks with essential hypertension, and 52 whites with secondary forms of hypertension (18 atherosclerotic renovascular hypertensives, 17 patients with fibromuscular disease, and 17 patients with primary aldosteronism). There were no significant differences in phenotype frequencies in ABO, Rh, Kidd, Kell, Duffy, P, Haptoglobin, PGM-1 or AcP in any of the comparisons. However, there was a significantly different distribution of MNS phenotypes in comparisons of essential and atherosclerotic renovascular hypertensives with normotensive controls. Essential hypertensives had a lower frequency of the S gene and a higher frequency of s in whites (X2 = 12.21, p less than 0.005). Atherosclerotic renovascular hypertensives differed from the normotensive population in the frequencies of both MN (X 2 = 4.34, p less than 0.05) and Ss (X2 = 4.21, p less than 0.05). The finding of disease-blood group associations supports the hypothesis that there may be significant physiological differences between individuals of different blood types.

Glycogen and protein concentrations and the activities of liver glycogen metabolic enzymes were measured in 22 children aged 4 to 15, suffering from extrahepatic portal hypertension. Glucose-6-phosphatase, amylo-1,6-glucosidase, fructose-1,6-diphosphatase, phosphorylases alpha and beta, phosphoglucomutase, and phosphohexose isomerase levels were analyzed. Liver biopsy specimens obtained by surgical marginal biopsy were used in the study. No or drastic reduction of phosphorylase alpha activity and reduction of glycogen concentration and glucose-phosphatase activity were found characteristic of extrahepatic hypertension. Analysis of correlations of the findings has demonstrated a medium correlation in 4 cases and a strong correlation between the findings in 1 case, the possibility being estimated as 0.95-0.99. The highest number of correlations was observed with phosphorylase alpha and glucose-6-phosphatase (3 correlations). Liver blood stream impairments result in injury to one of its main biochemical functions, i.e., the maintenance of blood glucose homeostasis, this leading to reduction of the adaptation potential of the body; this should be borne in mind when planning therapeutic measures for patients with extrahepatic hypertension.
