Study of microcirculation of the ocular ciliary body in experimental kidney disease.

We studied disorders in ciliary body microcirculation in experimental chronic glomerulonephritis with tubulointerstitial nephritis and evaluated the hemodynamic effects of low-frequency pulsed electromagnetic field in this pathology. Laser Doppler flowmetry demonstrated vasospasm with reduced nutrient blood fl ow in the ciliary body of animals with experimental chronic glomerulonephritis with tubulointerstitial nephritis. The exposure to low-frequency pulsed electromagnetic field using developed technology will lead to significant reduction of the vascular tone and improve arterial blood supply to the microcirculatory bed.

[Characteristics of the autonomic nervous system state in children with myopia associated with undifferentiated connective tissue dysplasia].

Autonomic nervous system disorders occur in 100% cases in patients with connective tissue dysplasia. Biomechanism of accommodation and autonomic innervation of ciliary body was not investigated clearly and presented as area of further research. The goal of the study was to evaluate features of autonomic nervous system in patients with myopia associated with connective tissue dysplasia. 50 children with myopia associated with connective tissue dysplasia went through ophtholmological examination. To evaluate function of autonomic nervous system all patients were observed with the machine "Valenta" which has ECG recording. As a result we found that children with myopia and connective tissue dysplasia have unsatisfactory adaptive reserves with imbalance of sympathetic and parasympathetic input, autonomic nervous system wasn't available to provide homeostasis in demanding level. We hypothesized that autonomic nervous system might be a reason which lead to disorders in process of accommodation during myopia and assist its progressing.

[Ultrastructural features of vascular iridociliary system after biopuncture by antihomotoxic medicine].

OBJECTIVE: To reveal ultrastructural features of iridociliary vessels after biopuncture with antihomotoxic medicine. METHODS: Myopia model was created on 10 rabbits by injecting all trans-retinoic acid in catheter Vasofix Certo 24G in left internal carotid artery until we got low myopia. After six months of daily injections all rabbits had myopia from -2,0 to 3,0 D. Animals were separated into two groups: 5 rabbits with daily intradermal injection in three points of upper eye lid without medicine during 10 days and 5 rabbits with daily intradermal injection in three points of upper eye lid with Cerebrum Compositum N during 10 days. Morphology of iridociliary system was explored. RESULTS: Biopuncture in myopia model increases level of metabolic reactions in iridociliary system, supplies adaptive reserves by the hemodynamic enrichment of ciliary body vessels and balance of autonomic nervous system impulsation.
