Shruthi, et al.: Immunomodulatory Effects of Gallic Acid in Swiss Albino MiceGallic acid is a triphenolic acid, widely distributed in fruits, vegetables and plants and is reported to produce antioxidant, antiinflammatory, antifungal, antiviral and antitumor effects. In the present study, immunomoduatory effect of gallic acid was tested against cyclophosphamide and cisplatin; two widely used anticancer agents induced immunosuppression in Swiss albino mice. Cyclophosphamide and cisplatin are known immunosuppressive agents, which elicit variety of immune responses. In recent years much attention is given for the identification of plants or their bioactive compounds as immunomodulators. Three different doses of gallic acid i.e., 100, 200 and 400 mg/kg weight were administered orally for 7 consecutive days. Cyclophosphamide (50 mg/kg) and cisplatin (10 mg/kg) were administered intraperitoneally as single dose. Levamisole 50 mg/kg was used as standard immunomodulatory drug. 0.5 % carboxymethyl cellulose was used as solvent control. Evaluation of immunomodulatory property of gallic acid was done by using haemagglutination antibody titre response and haematological parameters such as white blood cells, red blood cells, platelet counts and haemoglobin levels. Relative weight of thymus an important lymphoid organ was also determined. Augmentation of antibody titre values and haematological end points clearly indicated immunomodulatory effect of gallic acid against cyclophosphamide and cisplatin-induced myelosuppression in Swiss albino mice. Results indicate that, gallic acid could be used as an adjuvant with immunosuppressive drugs to reduce their adverse effects on immune system.

Background:Periodontitis is a local inflammatory process mediating destruction of periodontium triggered by bacterial insult leading to systemic inflammatory mayhem in the host. Epidemiologically, it has been modestly associated with cardiovascular diseases (CVD) with elevated acute-phase reactant C-reactive protein (CRP) and rheological variables such as total leukocyte count and differential leukocyte count (TLC and DLC), which are potential predictors of CVD.Aim:The aim of this study was to investigate the serum CRP level, leukocyte count in chronic periodontitis patients and their relation to the severity of chronic periodontitis.Subjects and Methods:This cross-sectional study comprised 30 subjects, of which 20 were diagnosed as chronic periodontitis based on the Gingival index, probing depth and clinical attachment levels and 10 healthy subjects as controls. Following, which peripheral blood samples were drawn and serum CRP, TLC and DLC were quantified using the turbidimetric immunoassay. Data was analyzed using Intercooled Stata 9.2 version, (Stata corporation, LP, USA) ANOVA, Mann Whitney U test and Newman-Keuls post hoc procedures. P values less than) 0.05 were considered as significantResults:The mean serum CRP levels were statistically significant (P < 0.05) in severe and moderate periodontitis subjects when compared with healthy controls. Leukocytes were significantly elevated in severe periodontitis compared with moderate periodontitis and controls; this finding was primarily explained by the increase in number of neutrophils.Conclusion:The increased serum CRP levels and neutrophils in chronic periodontitis subjects suggest an addition to the inflammatory burden of the individual potentially striking toward an increasing risk for cardiovascular events. Further research is needed to determine the specificity of these markers and their role in the inflammatory burden of one's systemic health.

HighlightsAntigenotoxic effect of septilin against cyclophosphamide (CP) an anticancer drug was evaluated in Swiss albino mice.In vivo micronucleus (MN) assays and sperm shape abnormality assay were used as test parameters.Pretreatment with septilin significantly decreased the clastogenic damage induced by CP.Protective effect of septilin may be due to the synergistic effects of individual plants/their constituents.
