Serum gastrin concentrations in healthy males and females of various ages.

We measured, by the RIA method, the concentrations of serum gastrin in a fasting state in 80 healthy volunteers of both sexes (M = 43, F = 37) aged 15-81 years. We did not find significant differences in the mean values of gastrin among them and the correlation of gastrin with the ages was insignificant. Further study of various age groups (15-29, 30-59, greater than 60 years) in both sexes and of two more age groups (18-45, 46-71) in the females, did not disclose any significant differences either. People of ages greater than 60 years had the greatest concentration of gastrin. Furthermore, we studied the concentrations of gastrin in the sera of 39 of these 80 people (M = 23, F = 16), aged 15-47 years, 10 min. and 40 min. after a test meal. No differences were found between the two sexes. However, although the mean levels of gastrin were significantly increased 10 min and 40 min after the meal in comparison with the fasting levels in both sexes, only in the men was the increase after 40 min. significantly greater than that after 10 min.

Reticuloendothelial phagocytosis in patients with chronic renal failure.

Using the clearance of microaggregated iodinated human serum albumin, the phagocytic function of the reticuloendothelial system was tested in 73 patients with chronic renal failure and in 30 normal subjects. Of the patients with chronic renal failure 26 were undergoing hemodialysis. Increased reticuloendothelial phagocytosis was shown in all patients with chronic renal failure. No correlation was shown between hematocrit-creatinine and T 1/2 (min) in patients with chronic renal failure.

The incidence of gallstones in Greece; an autopsy study.

In the fifty-year period, from 1925 to 1974, 6596 autopsies were performed at three departments of Pathology in Athens. The incidence of gallstones was 5.97% in the total material. The incidence in females was 8.86% and in males 4.52%, with a ratio 2:1. An increase of the incidence has been noticed since 1925. Under the presented data Greece could be included among the countries with an intermediate frequency of gallstones, but with a tendency to follow the Western countries pattern. The significance of the Greek standard of living and the dietary surveys on the gallstone formation, are briefly discussed.

Distribution of Gm and Inv factors in two samples of the Greek population.

Gm and Inv polymorphism has been investigated on a sample of the general Greek population (N = 256) and on a sample of the Achaia population of Northwestern Peloponnusus (N = 150). The estimated frequencies were, respectively in the two groups: Gm1, 0.156 vs. 0.180; Gm1,2,0.010 vs. 0.017; Gm4,12, 0.834 vs. 0.803; Inv (+1), 0.125 vs. 0.140.

The Gm and Inv factors in rheumatoid arthritis.

The Gm(1), Gm(2), Gm(4), Gm(12), and Inv (1) factors were studied in the sera of 56 patients suffering from rheumatiod arthritis and 26 from various rheumatic diseases, by the hemagglutination inhibition test, using optimally reacting mixtures of Ragg and Nagg sera. The distribution of these factors was found to agree with that of healthy Greeks. No correlation was found between hypergammaglobulinemia and the discovery of the Gm(1) and Inv (1) factors. The presence of the rheumatoid factor was independent of the Gm and Inv phenotypes.

The red cell acid phosphatase polymorphism in Greek b-thalassemia patients.

Red cell acid phosphatase polymorphism was studied by starch gel electrophoresis in 70 b-thalassemia patients and in 310 healthy Greeks. Our results gave the following gene frequencies; b-thalassemia patients: pa 0.321, pb 0.643, pc 0.036; healthy Greeks: pa 0.302, p b 0.653, pc 0.045. No statistically significant differences were found between the two groups.

Functioning metastatic parathyroid carcinoma.

A case of 53-year-old woman with a parathyroid adenoma and a parathyroid carcinoma with functioning metastases to the lungs, mediastinum and pleura is reported. The administration of inorganic phosphate solution failed to control hypercalcemia. The therapeutic methods available to deal with metastases are discussed.
