The effect of MLHT on DTH was

studied and the results were shown in Fig. 2. DTH reaction, in vehicle treated rats there was no change in paw edema after 1, 24, and 48 h. But H. tiliaceus extract shows the significantly decrease (P < 0.05) in the paw edema as compared to SRBC sensitized and pyrogallol induced rats. In the groups of rats with normal immune status, of MLHT (250 mg/kg/p.o.) and MLHT (500 mg/kg/p.o.) showed significant (P < 0.001) potentiated DTH response in terms of increase in the mean difference of paw edema at 48th hour when compared with control group. The effect of MLHT on hematological MEK inhibitor parameters on 28th day was reported in Table 2 both doses shown significant (P < 0.01)increase in WBC count whereas RBC and Hb showed dose dependent increase. The results showed that the increasing level of total protein in low and high dose MLHT treated animals. When compared to control, albumin level was not

significantly changed for both low and high dose. SGOT was slightly increased for both doses. SGPT was decreased during the study period for high dose. ALP was increased for both low and high dose during the experimental period. But when compared to control, significant changes were not observed in low dose. The results were given in Table 3. Immunomodulation is explained as any change in the immune response and may involve induction, expression, amplification of any part much or phase in the immune response.12 Use of herbs for improving the overall resistance of body against common

infections and Smad inhibitor pathogens has been a guiding principle of Ayurveda.13 Pyrogallol is a strong generator of free radicals,14 and it is evidenced that it can suppress the proliferation of mouse lymphocytes in vitro. H. tiliaceus which contains polyphenols, flavonoids etc., posses hepatoprotective, antioxidant, antimutagenic properties hence in the present study it was aimed to investigate methanolic leaf extract of H. tiliaceus for its immunomodulatory activity as the flavonoids and polyphenols are effective in possessing immunostimulant properties. The increase in the carbon clearance index reflects the enhancement of the phagocytic function of mononuclear macrophage and non-specific immunity. The adhesion of neutrophils to nylon fibers describes the margination of cells in the blood vessels and the number of neutrophils reaching the site of inflammation. The estimation of serum immunoglobulin levels was used to evaluate the increase in serum immunoglobulin production after the administration of the drugs. Immunoglobulins are antibodies that react specifically with the antigen, The indirect hemagglutination test was performed to confirm the effect of MLHT on the humoral immune system challenged with SRBC’s. It is composed of interacting B cell with antigens and subsequently proliferating and differentiating into antibody producing cells.
