<title>Laser method of biological activity stimulation of cryoconserved hemopoietic tissue transplant</title>

Abstract

The biological activity of cryoconserved fetal liver cells of mice (FLM) undergone the He-Ne laser action has been estiated by the efficiency of their transplantation to mice-recipients exposed to lethal X-ray dose .The survival rate 30 days after X-ray exposure for those mice was 75% in comparison with 70% for mice with cryoconserved nonirradiated graft. The trial animals' peripheral blood investigations have been made.The obtained results indicate that laser method of cryoconserved cells stimulation can help to increase the therapeutic efficiency of mielotranspiantation.
