Experimental morphological analysis of surgical bypassing of the uveal tract.

Histological preparations of eyeball membranes from rabbits subjected to decompression multisclerectomy providing alternative drainage pathway were examined. The procedure was performed with or without application of a 5-fluorouracil-impregnated implant. The use of this implant always resulted in the formation of relatively wide endothelialized transscleral channels and ensured their persistence in the late postoperation period.

[Morphological substantiation of selection of the method of surgical treatment of patients with prolapse of internal genital organs].

Morphology of uterine ligaments and the vaginal mucosa has been examined in 61 patients with uterine prolapse in order to provide guidelines for an optimum management with respect to tissue functional status. Specimens were obtained intraoperatively and examined in a usual microscope and a S-570 Hitachi scanning electron microscope (Japan). The study suggests that morphologic evaluation of the vaginal walls and uterine ligaments provides an exact measure of tissue status, offering an optimum choice of treatment in these patients.

[Distribution of cytoplasmic ferroproteins and iron in human kidney tumors].

Using immuno- and histochemical techniques, it has been shown that the primary tumoural node in kidney cancer is a locus with an extraordinarily high concentration of cytoplasmic ferroproteins and ferrum (Fe3+). Fe3+ is located in the cytoplasm of nephrothelium of tumour-affected kidney tubules, intensively incrustates the cell cytoplasm in the primary tumoural node and is revealed in separate nuclei of the primary node cells. Possible consequences of high local ferrum concentration in cells is discussed.
