Abstract
The ultrastructural changes and functional activity of the
hypothalamus in traumatic optical neuropathy, which was with methylprednisolone at a dose of 30 mg/kg and 15 mg/kg
in combination with phosphogenic stimulation with a current of
800 mA on the side of the defeat and 300 mA on the opposite
side. According to our research, it has been established that
traumatic damage to the orbital part of the optic nerve causes
structural destructive changes in the suprachiasal nucleus of
the hypothalamus in the form of hydrophobic and vacuoles
dystrophy. It was found that the treatment contributed to the
development of rejuvenating processes in the nucleus (more
pronounced in combined treatment than in monotherapy with
corticosteroids), changing its architectonics and increasing
the number of neurosecretory granules. Reduced content of
adrenocorticotropic hormone in the peripheral blood from
11,64±0,43 to 0,32±0,13 pg/ml (P<0,05) against the background
of a sharp increase in the content of cortisol from
92,31±3,26 to 290,12±6,72 μg/dl (P<0,05) in monotherapy
with methylprednisolone. When combined, the maintenance
of hormones (6,13±0,12 pg/ml and 6,93±0,14 μg/dl, respectively)
is closer to the group without treatment, and therefore,
obviously, it is more physiological as it is endogenous processes
of the organism. Consequently, contralateral phosphine
electrostimulation leads to the activation of neurosecretory
processes of the suprachioscular nucleus of the hypothalamus
and normalization of the content of hormones.
