| This study was designed to detection the effect of the soluble beta glucan (ß-glucan) local and commercial extracts (LE , CE) of the Saccharomyces cerevisiae on protein concentration of human circulating blood lymphocytes at the concentrations (5 , 50 , 500 , 1000 ) µg/ml .The results showed significant differences increase on protein content at the level (P<0.05) for both effect of beta glucan Local extract , Commercial extract , and the best effect on protein lymphocytes concentration demonstrated at the highest concentration of the LE and CE .The four concentrations of β-glucan (5 , 50 , 500 and 1000 µg/ml) caused significant differences (p < 0.05) in protein content of lymphocytes secretion that treated with Local and Commercial extracts which represented (45.90, 63.18, 83.2, and 184.1)µg/ml and (32.27 , 50.45 , 79.54, 164.1) µg/ml respectively , as a compared to their control negative and control positive (58.63 ; 110.45) respectively µg/ml . While the values of both treatment at concentration (5,50,500)µg/ml is lower than control group that treated with (PHA) was represented (110.45) µg/ml . The concentrations 1000 µg/ml of LE, CE have best effect on protein concentration of lymphocytes secretion when compared with the control groups . |
