To each, 0.1 ml of serum was added from a pipette. They were inverted to enable complete mixing of the reagents and left to stand for 1 h

at room temperature. The first tube served as blank and the second tube was taken as sample. The turbidity developed was measured using a digital nephelo-turbidity meter. The turbidity obtained (sample-blank) was compared with that obtained with standard barium sulfate (BaSO4) solution. The turbidity obtained with this solution was expressed as 20 zinc sulfate turbidity (ZST) units. On day 28 the fresh whole blood samples were used for the estimation of hemoglobin, RBC, WBC, Hb. On 28th day blood sample was collected and the biochemical Selleckchem GSK126 parameters like SGOT, SGPT, Total bilirubin, albumin were analysed using standard methods by semi auto analyzer. Experimental data obtained were analyzed with the software. Variance between groups was analyzed by ANOVA, means of groups were compared by Tukey-test. Differences with P < 0.001were considered statistically significant. The effect of MLHT on carbon clearance was studied and the results of phagocytic index were presented in Table 1, Both doses of MLHT (250 mg/kg & 500 mg/kg) showed significant (P < 0.001)

increase in the phagocytic index when compared to control indicating that there was increase in the clearance of colloidal carbon from the blood after administration of these drugs. Effect of MLHT on neutrophil adhesion was studied on 14th day VX-770 price and the results were given in Table 1. Incubation of blood with nylon fibers (NF) produced a decrease in the neutrophil counts due to adhesion of neutrophils to the fibers. Both doses of MLHT showed significant increase (P < 0.001) in the neutrophil adhesion

when compared to control. The high dose of MLHT was found to be more effective than low dose. There was also rise in neutrophil count in untreated blood of all treatment groups. Humoral immune response by MLHT was studied on day 13th and 21st and data is represented in Fig. 1. On 13th and 21st day of the study, rats from all the groups were challenged, with SRBCs in normal saline (0.1 ml of 20% Amisulpride SRBCs) intraperitoneally. On treatment with MLHT, 250 mg/kg and 500 mg/kg, the haemaglutination antibody titer on 13th and on 21st day (P < 0.001) showed dose dependent effect in the antibody titer, when compared to the immunosuppressed control group. With MLHT500 mg/kg, the haemaglutination antibody titer shown significant (P < 0.001) increase on 21st day when compared to the immunosuppressed control group. The estimation of serum immunoglobulin levels was used to evaluate the increase in serum immunoglobulin production after the administration of the drugs. On administration of MLHT, 250 mg/kg and 500 mg/kg, p.o, once daily to the groups IV and V there was a significant increase (P < 0.001) in the serum immunoglobulin levels, when compared to the immunosuppressed control group (G-II).
