Effects of chronic hypotension on the adrenergic nervous plexus of the saphenous artery in rats and its regeneration after femoral nerve injury.

The effects of chronic hypotension on the density and intensity of fluorescence (after treatment with glyoxylic acid) of the plexus of adrenergic fibers in the wall of the saphenous artery and on the reinnervation of this vessel were studied in Wistar rats. Regional hypotension in the vascular bed of the hind part of the rats' bodies was induced by stenosis of the abdominal part of the aorta distal to the renal arteries. After four weeks, the saphenous artery was denervated in one limb by resection of a segment of the femoral nerve.

[Effect of chronic hypotension on the adrenergic nerve plexus of the rat a. saphena and on its regeneration after femoral nerve injury].

The influence of chronic hypotension on density and fluorescence intensity (after glyoxylic acid treatment) of periarterial plexus of nerve fibers in saphenous artery wall and on reinnervation of this vessel was studied in Wistar rats. Regional hypotension in the rat hindquarters vascular system was created by partial occlusion of abdominal aorta distally to the renal arteries. Four weeks later, the segment of femoral nerve was resected in one of the limbs to denervate the saphenous artery.

[Innervation of adrenal glands in some types of cardiovascular pathology].

We examined adrenal glands obtained at early autopsy of 56 men aged 21-70 years. According to the age five groups of cases were distinguished. The study was performed with the use of methods of silver impregnation of nerve plexuses and planimetric pointcounting.

[Morphological and morphometrical changes in nervous apparatus of the adrenal medulla after sudden death of patients with various cardiac pathology].

Adrenal glands were studied at early autopsy of 28 men aged 35-60 years after their sudden cardiac death. According to the presence and character of pathologic manifestations detected in myocardium, three groups of cases were distinguished: group 1 (control) included the people without myocardial pathology (traffic accident victims), group 2 consisted of the patients with ischemic heart disease (IHD) in association with recent myocardial infarction, group 3 included the patients with IHD and hypertension. The study was performed using the methods of silver impregnation of nerve terminals and planimetric point-counting method.

[Adrenergic nerve plexuses of heart and adrenal and myocardial catecholamines of spontaneously hypertensive rats under the influence of electromagnetic irradiation in the millimeter range].

Condition of adrenergic cardiac and adrenal nervous plexuses of Kyoto-Wistar Rats (WKY) and spontaneously hypertensive rats (SHR) was examined by quantitative neurohistochemical methods before and after extremely high frequency field (EHF field) influence of "Bayur" microwave therapy apparatus in mode 1 (42,194 MHz frequency, 7.1 mm wavelength) and in mode 3 (53,534 MHz frequency, 5.6 mm wavelength).
