Glucan as stimulator of hematopoiesis in normal and gamma-irradiated mice. A survey of the authors' results

Abstract

Glucan, a beta-1,3-linked polyglucose derived from the yeast Saccharomyces cerevisiae, is a broad spectrum enhancer of host defense mechanisms stimulating humoral and cell-mediated immunity. On the basis of these features, glucan has been tested by the authors' research group in experiments on gamma-irradiated mice. Two glucan forms, particulate and soluble, have been studied. Attention has been focused on various application regimens in relation to the time of irradiation (pre- or postirradiation application), the possibilities of using glucan in various radiation regimens (single or repeated irradiation), combined pharmacological therapy (joint administration of glucan with cystamine or inhibitors of prostaglandin synthesis), and on the negative side effects of therapy with glucan. Some studies included also experiments on unirradiated mice. The results have demonstrated the ability of glucan to influence positively the course of the acute radiation disease. Stimulation of hematopoiesis has been found to be the most important mechanism of glucan's radioprotective effects. In this communication, the results of 11 full-length articles are summarized and discussed.
