[Principles of functioning of various systems of the human body in the post-aggressive period]. / Printsip raboty nekotorykh sistem organizma cheloveka v postagressivnom periode.

The authors' investigations provide the conclusion that in a post-aggressive period there are organized cyclic fluctuations in the body hormones, penetrability of vessels, electrolytes and blood cells. The cycle takes 48 hours.

Comparison of peripheral and portal (via the umbilical vein) routes of insulin infusion in IDDM patients.

Twelve subjects with insulin-dependent diabetes mellitus were treated using continuous subcutaneous insulin infusion (CSII) and intraportal insulin infusion (IPII) via the umbilical vein for 4 mo. Glucose control improved in both CSII and IPII groups, but a decrease in glucose and HbAIc was more rapid and more significant in the IPII group than in CSII, even though insulin requirement was lower during IPII than CSII (40 +/- 2 vs. 50 +/- 2 U/day, P less than 0.05). The insulin plasma fasting levels were different (88 +/- 10.7 in the IPII group vs. 263 +/- 23 pM in CSII, P less than 0.001). High plasma levels of lactate, pyruvate, alanine, cortisol, and growth hormone were decreased in both groups, with their full normalization only in the IPII group. Glucagon concentrations were low in both groups at the beginning of the study (30.0 +/- 4.1 in the CSII group and 32.3 +/- 1.8 ng/L in IPII); they were equalized to control values in the IPII group and were low in the CSII group at the study's end (46.0 +/- 3.7 in IPII vs. 31.7 +/- 3.1 ng/L in CSII, P less than 0.05. We conclude that intraportal administration of insulin via the umbilical vein at rates of 0.01-0.05 U.kg-1.hr-1 reduces plasma levels of glucose, three carbon precursors, cortisol, and growth hormone by a direct action on the liver, and the hepatic action of peripherally administered insulin is manifested only when the infusion rate is increased to 0.1-0.3 U.kg-1.hr-1.(ABSTRACT TRUNCATED AT 250 WORDS)

[Interspecies similarity of the trajectory of reactive leukocytosis]. / Mezhvidnoe skhodstvo traektorii reaktivnogo leikotsitoza.

Reactive leukocytosis was studied in 60 patients after appendectomy by daily test for 8 days. Reactive leukocytosis trajectory in these patients was compared to the analogous trajectory in 87 dogs with experimentally induced inflammation. The similarity of reactive leukocytosis trajectory in humans and animals has been established and a uniform period of leukocyte blood count changes equal to 48 h has been determined.
