[Changes in the neural activity of the blood serum from patients with ischemic heart disease].

The isolated neurons of snail (Lymnaea stagnalis) were as test object for the evaluation of the blood serum neuroactivity. The blood serum was tested before treatment and after six applications of intravenous laser therapy (ILT). All blood serum specimens produced depolarization of the cell membrane potential.

[The effect of the blood serum from patients subjected to intravenous laser therapy on the parameters of synaptic transmission].

The effect of serum of patients with myocardial ischemia after low-level laser therapy on parameters of synaptic conductance of rat hippocampal neurons was investigated. The serum from patients with an initially low level of neuronal activity obtained after determination of laser irradiation increased the amplitude and that from patients with high activity. Thus the process of normalization of these parameters was observed.

[The mapping of cortical interaction in the asthenic neurosis syndrome].

Topographic mapping method was used to study the spatial-temporal organization of neocortical electrical activity at norm and asthenic neurosis. Patients with asthenic syndrome had shown right hemisphere dominance by the number of cortical interconnections in theta-band and interhemispheric discordance by coherence function.

[A comparative analysis of the chemiluminescence of capillary and venous blood granulocytes].

The parameters of zymosan-stimulated luminol-dependent chemiluminescence of whole capillary and venous blood were compared in patients with chronic nonspecific diseases of the lungs. The parameters of a chemiluminescence response were in good correlation in general, but the mean values of luminescence intensity of granulocytes from the blood collected from the finger were 1.6 times lower that may be explained by the inhibiting effects of the lymph and intercellular fluid.

[Susceptibility of rat thymocyte subpopulations to thymosine affecting their protein synthesis and dexamethasone receptors].

Protein synthesis and reception for 1,2-3H-(N)-dexamethasone were studied in A, B, C, D subpopulations of rat thymocytes after treatment with thymosine, cyclic adenosine-3,' 5'-monophosphate (cAMP) and caffeine. Thymosine inhibited the 1,2-3H-(N)-dexamethasone reception in rat thymocyte subpopulations A, B and C by 30-40%, stimulated the protein synthesis in A and B fractions by 30% as well as inhibited the synthesis in D fraction by 14%. Caffeine, administered together with thymosine, inhibited the protein synthesis by 80% in C and D thymocyte subpopulations and - by 47% in B subpopulations.
