title: [The effect of fungal and yeast glucan and levamisole on the level of the cellular immune response in vivo and leukocyte phagocytic activity in mice].
abstract: The level of cell-mediated immune response in vivo was investigated using the test of delayed hypersensitive reaction (DHR) to DNFB, along with the phagocytic activity (PA) of blood leucocytes in mice after subcutaneous implantation of fungal and yeast glucan and levamisol in dependence on the dose and administration schedule. The soluble form of fungal glucan (Pleurotus ostreatus) potentiated the DHR significantly at a dose of 10 mg/kg (but not at a dose of 50 mg/kg) while it was administered during DNFB sensitization (P < 0.05)-Tab. I and when its pre-medication effect was investigated (days -7 and -14; P < 0.05) with regard to the time of sensitization (Tab. II). The identical dose of glucan also had a positive effect (P < 0.05 or 0.01) on the percentual proportion of phagocytic cells (PC) reaching the maximum in the 2nd and 3rd week of investigation, as well as on the phagocytic activity index (P < 0.05; 3rd week) and percentage of neutrophil granulocytes (P < 0.05; 2nd week)-Tab. III. Yeast glucan (Saccharomyces cerevisiae) showed a potentiating effect on the DHR to DNFB only in the case of its pre-medication use; its soluble form was effective at both doses (10 mg and 50 mg/kg) in days -7 and -14 (P < 0.05), and its corpuscular form at a dose of 50 mg/kg on days -7, -14 and -21 (P < 0.05 or 0.01)-Tab. II. PA parameters of blood leucocytes displayed a stimulative effect only on the PC percentage. The most significant effects in this case were observed in the soluble form (both doses) in the 2nd and 3rd week (P < 0.01 and 0.05, resp.) and in the insoluble form (both doses) in the 3rd and 4th week of observation (P < 0.05 and 0.01, resp.). An increase in the number of neutrophil granulocytes was significant in the 2nd (P < 0.05 or 0.01; corpuscular form) and 3rd week of the experiment (P < 0.01; soluble form)-Tab. III. Levamisol affected both investigated parameters (DHR and PA) only at a dose 20 mg/kg (10 mg/kg-no effect). Its potentiating effect on the DHR level was observed both for its administration at the time of sensitization (P < 0.05) and for its administration on days 7 (P < 0.05) and 14 (P < 0.01) before DNFB sensitization (Tabs. I and II). A statistically significant increase in PC was recorded in weeks 2, 3 and 4 (P < 0.05 or 0.01), a statistically significant increase in the number of neutrophil granulocytes in the 3rd week of investigation (P < 0.05). The phagocytic activity index was not affected.
