[State of neuroendocrine systems and immunity in patients with burns].

The study of hormonal shifts and immunity in 95 patients with burns has revealed hyperergic reaction of the neuroendocrine system in the early period after trauma, accompanied by a marked and prolonged inhibition of cellular and humoral immunity. The use of antistress agents (clofelin, pentamine) and intravenous laser blood irradiation leads to a more prompt arrest of hyperergic reaction of the neuroendocrine system and to the reduction of immunosuppressing effect of burn trauma, which decreases the number of pyoseptic complications from 26.4 to 16% and total lethality from 16 to 3.

[The morphofunctional instability of the lymphocyte membrane in patients with chronic kidney failure].

T-lymphocyte E-receptor activity, mobility of the surface and deep parts of lymphocytic membrane lipid bilayer and membrane transport function were studied in 47 patients with chronic renal failure (16 had a conservatively curable and 31 terminal stages). A rosette test, polarization of the fluorescent probes I-anilino-naphthaleno-8-sulfonate and pyrene, inclusion of 14C-uridine into immunocompetent cells were employed, respectively. The investigations demonstrate morphofunctional instability of the lymphocytic membranes as indicated by shifts in RFC E-receptor activity, in reduced microviscosity of the lipid bilayer and transport dysfunction.

[The morphofunctional instability of the lymphocyte membranes in patients with chronic kidney failure].

A rosette test, fluorescent probing (1-aniline-naphthaline-8-sulfonate and pyrene) and 14C-uridine inclusion into immuno-competent cells were used to investigate T-lymphocyte membrane E-receptor activity, mobility of the surface and deep parts of lymphocytic membrane lipid bilayer, and membrane transport, respectively. A total of 16 patients with conservatively curable and 31 patients with a terminal stage of chronic renal failure (CRF) were examined. The lymphocytic membranes were found unstable: E-receptor activity of RFC changed, microviscosity of the surface and deep lipid bilayer diminished, the transport function got disturbed.
