HEPATOPROTECTIVE, ANTIDIABETIC, AND ANTIPYRETIC ACTIVITY STUDIES OF SIDDHA FORMULATION – NILAVEMBU KUDINEER

Objective: Traditional medicines like Siddha System of Medicine are one of the most primitive medical system. It plays a major role in treating ailments of humankind. Nowadays, this system flourished throughout India using Nilavembu kudineer (NVK) as a drug to treat in various outbreaks such as dengue, Chikungunya, and other related virus infections. As per literature, NVK indicated many types of fever and various diseases. This study emphasizes on antipyretic, antidiabetic, and hepato protective activities of NVK by In vitro study methods. Methods: Hepatoprotective effect of NVK on Carbon tetrachloride-induced hepatotoxicity in the rat in five groups, antipyretic activity tested by subcutaneous injection of 10 ml/kg of 15% w/v yeast suspended in 0.5% w/v carboxymethyl cellulose solution for elevation of body temperature of rats in 6 groups. Antidiabetic activity done by administration of streptozotocin dissolved in citrate buffer (pH 4.5) and nicotinamide, intraperitoneal injection of 60 mg/kg streptozotocin, 15 min after the i.p administration of 120 mg/kg of nicotinamide in non-insulin-dependent diabetes, in six groups. Results: The hepatoprotective effect having the significance of one way ANOVA followed by Dunnett’s (n=6); nsp>0.05, *p<0.05, **p<0.01, and ***p<0.001, calculated by comparing treated groups tumor with the control group. Antidiabetic activity having the significance of Dunnett’s ***p<0.001, **p<0.01, and *p<0.05 calculated by comparing the treated group with the control group and antipyretic activity results in Dunnett’s *p<0.05 calculated by comparing the treated group with the control group were considered to be significant. Conclusion: The study shows that NVK having the potency of hepatoprotective and capability of diabetes in vitro studies. This study also revealed the potency of antipyretic activity against yeast

Synergistic Effect of Ramie and Pineapple Fibres Reinforcement on The Strength of Epoxy Matrix Composite

Natural fibre reinforced composite of pineapple and ramie fibre unidirectional mats were fabricated through handlayup process and curing through compression molding process. Six samples of the composite material with different combinations of alternating fibres and orientations of the fibre mats were fabricated and tested for their mechanical properties. It was observed that the stacking sequence, type of fibre and orientation of the fibres make a pronounced difference in the mechanical properties. The outer layer of Ramie fibre mat and the 45° orientation of either of the fibres resulted in better mechanical properties. By making a perfect combination of the stacking sequence of the fibres, type of fibres and orientation, it is possible to enhance the properties of the composite

Quantity of Vaccine Poliovirus Shed Determines the Titer of the Serum Neutralizing Antibody Response in Indian Children Who Received Oral Vaccine

Replication of oral poliovirus vaccine (OPV) in the intestine (ie, vaccine take) is associated with seroconversion and protection against poliomyelitis. We used quantitative polymerase chain reaction analysis to measure vaccine shedding in 300 seronegative infants aged 6–11 months and in 218 children aged 1–4 years 7 days after administration of monovalent or bivalent OPV. We found that the quantity of shedding correlated with the magnitude of the serum neutralizing antibody response measured 21 or 28 days after vaccination. This suggests that the immune response to OPV is on a continuum, rather than an all-or-nothing phenomenon, that depends on efficient vaccine virus replication
