Immunohistochemical and morphometric analysis of effects of vilon and epithalon on functional morphology of radiosensitive organs

Plain-language summary

Paraphrased from the published abstract below — not a verdict on whether anything works.

This rat study examined effects of the peptides vilon and epithalon on the functional morphology of the thymus, spleen, and duodenum in intact rats and in rats exposed to a single whole-body dose of 6 Gy gamma-irradiation, using immunohistochemistry and morphometry. The authors report that vilon stimulated proliferative activity of thymocytes and enhanced proliferative potential of intestinal stem cells, which they link to postradiation recovery of these organs. Epithalon was reported to slow metabolic processes in the duodenal mucosa and to suppress hemopoiesis and lymphopoiesis in the spleen. Species: rats.

Abstract

Studies of the effects of vilon and epithalon on functional morphology of the thymus, spleen, and duodenum in intact rats and rats exposed to single whole-body gamma-irradiation in a dose of 6 Gy showed that vilon stimulated proliferative activity of thymocytes and enhanced proliferative potential of stem cells in the intestine, thus stimulating the postradiation recovery of critical organs. Epithalon decelerated metabolic processes in the duodenal mucosa and suppressed hemopoiesis and lymphopoiesis in the spleen.
