In this study we paid a special attention to analysis of surgical interventions conducted using transcervical, transparotid and transoral approach for neoplasm removal and revise complications arising in postoperative period in various types of PPS tumors. Results. The largest number of patients presented with benign salivary gland tumors 22 (68.7%), followed by malignant salivary gland neoplasms 5 (18.5%), neurogenic tumors 4 (12.5%), and miscellaneous tumors 1 (0.3%). Postoperative complications for malignant salivary gland surgeries occurred at the highest rate (42%), whereas, for benign -at the lowest (5%). Transcervicalsubmandibular, transparotid, and transoral approach was used in 56, 25, and 1% of surgeries, accordingly, whereas, mandibulotomy applied in 17%. "First bite syndrome" was noticed in 30% of the cases, cranial nerve palsies -in 20%, temporary, permanent facial nerve and accessorial nerve injury in 4, 1 and 15% of surgical interventions, accordingly. Vascular trunks damage occurred at 9%, and, mostly, for poststyloid lesions. Conclusions. Heterogeneous PPS tumors show a wide spectrum of postoperative complications and require a selective approach for optimization of surgical intervention and treatment strategy. MATERIALS AND METHODS

Splenosis is the autotransplantation of splenic tissue that occurs in patients over a period of time as the outcome of a traumatic rupture of the spleen in an anamnesis. In most cases, splenic foci occur in the abdomen and small pelvis due to dissemination of fragments of the spleen tissue during it's rupture, however these heterotopic foci can occur almost anywhere in the body, and their diffuse nature may cause suspicion of metastatic cancer. Our case of abdomen and retroperitoneal space splenosis in combination with right kidney cancer, is a rare observation.

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.
