A small drop of the suspension was spread on a glass slide, fixed in methanol and stained with
May�CGrunwald and Giemsa. A minimum of 2000 PCEs per animal were scored for the incidence of MNPCEs and also the ratio Akt signaling pathway of PCEs to the total erythrocyte was estimated by counting a total of at least 200 erythrocytes.[12,13] Biochemical estimation MDA The MDA content was determined in terms of thiobarbituric acid reactive substances formation. The extent of lipid peroxidation was calculated from the standard curve using 1,1,3,3-tetramethoxy propane and expressed as nM MDA/g of tissue. GSH The determination of reduced glutathione level in liver tissue was carried out using method of Ellmann with certain modifications. Briefly, the tissue homogenate was centrifuged and the obtained supernatant was mixed with 10 mM Ellman's reagent. After 20 min, absorbance of mixture was measured at 412 nm. The reduced GSH content was calculated from the standard curve using reduced glutathione and expressed as nM GSH/g of tissue. Statistical analysis The experimental results have been expressed as Mean �� SD (in vitro) and Mean �� SEM (in vivo). The data were analyzed by One-way analysis of variance (P <0.05) followed by Tukey's Multiple Comparison Test. RESULTS Preliminary phytochemical screening The phytochemical screening of extracts
revealed the presence of bioactive EPZ-6438 chemical structure constituents like alkaloid, carbohydrate, phytosterols, flavonoids, proteins and diterpenes. In vitro antioxidant assay Nitric oxide scavenging activity The plant extracts showed a good nitric oxide scavenging activity between 50 and 800 ��g/ml dose dependently [Table 1]. Among the extracts, AQEBM had shown better scavenging power than ETEBM, Montelukast Sodium however, the effect of ascorbic acid was much
less when compared to the extracts. Table 1 Percent NO scavenging activity and percent DPPH scavenging activity of ASA, AQEBM and ETEBM DPPH free radical scavenging assay AQEBM and ETEBM demonstrated a dose dependent antioxidant activity in the DPPH radical scavenging assay [Table 1]. The standard ascorbic acid possess highest DPPH scavenging activity of 99.216% at 80 ��g/ml, whereas, the aqueous and ethanolic extracts possess highest DPPH scavenging activity of 77.07% and 68.79% at 80 ��g/ml, respectively. In vivo anticlastogenic activity Peripheral blood micronucleus test A reduced number of cells in mitosis were found in CP treated group at 24 and 48 h. On the other hand, an increase in the number of mitotic cells was observed in the mice treated with AQEBM and ETEBM at 24 h as well as 48 h [Table 2]. Table 2 Percent mitotic index and percent micronucleated polychromatic erythrocytes in peripheral blood cells of mice at different recovery times The frequencies of MNPCEs induced by CP in peripheral blood of mice were extremely significant (P <0.001) to that of the normal group [Table 2].
