Local injection of verapamil into ventrolateral region of the medulla oblongata triggered the release of epinephrine. Verapamil increased the total content of norepinephrine and epinephrine by 560% and decreased the content of serotonin by 46%. Verapamil had no effect on norepinephrine/epinephrine and norepinephrine/(norepinephrine+epinephrine) ratios in normal rats. Blockade of K+-channels in the medulla oblongata by local injection of 0.001 mg amiodarone did not change the levels of epinephrine and norepinephrine and norepinephrine/epinephrine and norepinephrine/(norepinephrine+epinephrine) ratios. In the medulla oblongata, verapamil proportionally increased the levels of norepinephrine, dopamine, and L-DOPA. Similarly, amiodarone increased the levels of L-DOPA and dopamine by 2.6 and 3.2 times, respectively. Amiodarone shifted the ratio of neuroactive amino acids towards inhibitory transmitters.

We demonstrated specific changes in platelet structure in different types of tuberculous process, in particular, shift in the proportion between alpha-granules, dense granules, different disorders in the mitochondrial and lysosomal apparatus, etc. The role of platelets in immune process is studied. Redistribution of alpha-granules in platelets finds a new interpretation in light of psycho- and neurotropic effects of their contents. Adhesion and aggregation processes and granule release from platelets are regulated by the content of serotonin and cyclic nucleotides in these cells.

Erythrocyte disintegration processes are more pronounced in meningeal tuberculosis, which is associated with a shift in isoform spectrum of hemoglobin, catalase inhibition, and a sharp aggravation of lactoacidosis. The severity of erythrocyte disintegration cannot serve as a criterion of differential diagnosis of tuberculosis severity.
