Inflammation is characterized as a local reaction to the injury of any agent by living mammalian tissue. This is a body defense reaction for eliminating or reducing the spread of the damaging agent, followed by removal of the cells and tissues of necroses. Aqueous extract of Hyptis suaveolens whole plant has been evaluated for anti-inflammatory activity on albino wistar rats by computing the carrageenan-induced paw edema suppression formed by 500mg/kg and 250mg/kg aqueous extracts. Lower dose (250 mg/kg) also suppresses edema formation significantly, when compared to control but unable to reach significant level as 500 mg/kg extract. Indomethacin suppresses the edema formation significantly when compared to the control. Indomethacin has been used as the standard drug. Anti-inflammatory effect was further assessed using stair climbing Activity, motility test and Cytokine assay methods. Stair climbing score, motility score was significant in case of 500 mg/kg of plant extract when compared to control. In Cytokine assay, IL-10, IL-6, and TNF-α have been assessed. IL-10, IL- 6, and TNF-α have been reached to near normalcy after treatment with standard (Indomethacin) and Hyptis suaveolens whole plant aqueous extract (250mg/kg and 500mg/kg). The results of the study rationalize the conventional utilization of plants as an anti-inflammatory agent.

This study assessed the probable effects of Ethanolic extract of Tanacetum parthenium (EETP) whole plant as hepatoprotective compound that acts on damaged liver due to administration of Sodium arsenite (NaAsO2 — 3mg/kg) in Wistar albino rats for a period of 28 days which results in alteration in Lipid peroxidation, antioxidant enzymes, biochemical factors, and liver enzyme. 30 animals were utilized for the study and are divided into five groups containing 6 rats each. Group –I treated as control received water, Group II-V were treated with sodium arsenite. Group-III received Vitamin-E (reference drug), Group IV treated with EETP 200 mg/kg dose and Group V treated with 400 mg/kg dose after hepatotoxicity induced by Sodium arsenite. Safeguarding effects of Ethanolic extract of Tanacetum parthenium whole plant were screened by analysis of the parameters like alanine transaminase, aspartate transaminase, alkaline phosphatase and total bilirubin, malondialdehyde, antioxidant enzymes. It was explored that administration of EETP at different doses could significantly decrease the enzymatic measures of AST, ALP, ALT, and TB concentration and increase catalase, GSH, GR and GPx levels in comparison with Sodium arsenite-induced control group. The data obtained from this experimental study prefigured the antioxidant potential of EETP and its potential hepatoprotective effects, and its beneficiary therapeutic effects on vandalization or disfigurement of liver due to Sodium arsenite induction in experimental animals.

A highly selective, sensitive and accurate HPLC method has been developed and validated for the estimation of three fluoroquinolones (FQs) viz., gatifloxacin (GFC), sparfloxacin (SFC) and moxifloxacin (MFC) with 500 microL human plasma using levofloxacin (LFC) as an internal standard (IS). The sample preparation involved simple liquid-liquid extraction of GFC, SFC, MFC and IS from human plasma with ethyl acetate. The resolution of peaks was achieved with phosphate buffer (pH 2.5)-acetonitrile (80:20, v/v) at a flow rate of 1 mL/min on a Kromasil C(18) column. The total chromatographic run time was 18.0 min and the simultaneous elution of GFC, SFC, MFC and IS occurred at approximately 10.8, 12.8, 17.0 and 6.0 min, respectively. The method proved to be accurate and precise at linearity range of 100-10,000 ng/mL with a correlation coefficient (r) of > or =0.999. The limit of quantitation for each of the FQs studied was 100 ng/mL. The intra- and inter-day precision and accuracy values found to be within the assay variability limits as per the FDA guidelines. The developed assay method was applied to a pharmacokinetic study in human volunteers following oral administration of 400 mg GFC tablet.
