[Histological studies of carbon felt (carbotextim M) in late periods after its orbital implantation].

The authors performed histological studies of a grown carbon felt implant and its adjacent tissues in late postoperative studies. During planned operations (cavity or stump correction), pieces of a grown implant with its adjacent tissues were taken for examination from 25 patients in whom carbon had been earlier implanted during enucleation and delayed stump plastic repair. Morphological studies indicated that mature connective tissue had grown between the fibers of the implant, that a connective tissue capsule had formed around the whole implant, and that there was no inflammatory reaction in both the implant itself and its adjacent tissues.

[New modification of autoconjunctival plastic surgery in urgent corneal surgery].

A new modification of plastic repair of deep defects of the cornea was performed: autoconjunctival plasty of the cornea with a flap on a pedicle with its rigid fixation in the corneal bed. The operation was carried out in 30 patients with infectious, trophic, and autoimmune involvement of the cornea, 24 of these with perforation of the cornea. The patients were observed for 1 year after the operation.

[Experimental study of cytokines complex inhibitory effect on wound healing after glaucoma filtering operations: histopathological and immunochemical findings].

Experiments on a model of glaucoma filtering operation in 25 rabbits showed that the natural cytokine complex inhibited the operation wound healing in comparison with the control. The complex was prepared by an original method (culturing peripheral blood leukocytes) at Immunology Department of the Russian State Medical University. Histopathological study revealed delayed formation of cicatricial tissue under the effect of cytokines.

[Clinical and histopathological examination of enucleated eyes with contusion ruptures of cornea after radial keratotomy].

Histopathological (histological, histochemical, and morphometric) examinations of 8 enucleated eyes with contusion ruptures of the cornea 2-13 years after radial keratotomy showed two patterns of changes caused by contusion and peculiar reparative processes in the keratotomic incisions. A characteristic feature of contusion injury after radial keratotomy is combination of changes typical of contusion and an extensive perforating corneal wound after its rupture along the incisions. Reparative processes in the keratotomic incisions were regarded as incomplete cicatrization resultant from inhibition of keratoblastic activity after a low-traumatic operation.
