    This study investigated the possible anti-inflammatory, analgesic, and antipyretic effects of ethanolic extract of Pedalium murex Linn. fruits in selected experimental animal models. Anti-inflammatory activity of  Pedalium murex Linn., with doses of 200 mg/kg and 400 mg/kg, p.o., was evaluated by Lambda-carrageenan induced paw oedema in Wistar albinorats; analgesic activity with doses of 280 mg/kg and 560 mg/kg, p.o., was evaluated by hot plate method and acetic acid induced writhing method in Swiss albino mice; and antipyretic activity with doses of 110 mg/kg and 220 mg/kg, p.o., was evaluated in New Zealand white rabbits by injecting gram –ve lipopolysaccharide obtained from E. coli. Results were analysed by one way ANOVA followed by Dunnet’s multiple comparison test.  Pedalium murex Linn. showed significant anti-inflammatory activity from 15 min to 180 min as compared to vehicle treated animals. It was comparable to diclofenac sodium at 180 min. The extract did not prolong the reaction time on hot plate method but significantly reduced the number of writhing after acetic acid administration. Also the extract did not show any antipyretic activity on lipopolysaccharide induced pyrexia. It is therefore concluded that the ethanolic extract of Pedalium murex Linn. fruits has an anti-inflammatory and peripheral analgesic effects.Keywords: Anti-inflammatory, Analgesic, Antipyretic, Pedalium murex Linn., Carrageena

    BACKGROUND: There is a spectacular rise in the global prevalence of type 2 diabetes mellitus (T2DM) due to the worldwide obesity epidemic. However, a significant proportion of T2DM patients are non-obese and they also have an increased risk of cardiovascular diseases. As the Goto-Kakizaki (GK) rat is a well-known model of non-obese T2DM, the goal of this study was to investigate the effect of non-obese T2DM on cardiac alterations of the transcriptome in GK rats. METHODS: Fasting blood glucose, serum insulin and cholesterol levels were measured at 7, 11, and 15 weeks of age in male GK and control rats. Oral glucose tolerance test and pancreatic insulin level measurements were performed at 11 weeks of age. At week 15, total RNA was isolated from the myocardium and assayed by rat oligonucleotide microarray for 41,012 genes, and then expression of selected genes was confirmed by qRT-PCR. Gene ontology and protein-protein network analyses were performed to demonstrate potentially characteristic gene alterations and key genes in non-obese T2DM. RESULTS: Fasting blood glucose, serum insulin and cholesterol levels were significantly increased, glucose tolerance and insulin sensitivity were significantly impaired in GK rats as compared to controls. In hearts of GK rats, 204 genes showed significant up-regulation and 303 genes showed down-regulation as compared to controls according to microarray analysis. Genes with significantly altered expression in the heart due to non-obese T2DM includes functional clusters of metabolism (e.g. Cyp2e1, Akr1b10), signal transduction (e.g. Dpp4, Stat3), receptors and ion channels (e.g. Sln, Chrng), membrane and structural proteins (e.g. Tnni1, Mylk2, Col8a1, Adam33), cell growth and differentiation (e.g. Gpc3, Jund), immune response (e.g. C3, C4a), and others (e.g. Lrp8, Msln, Klkc1, Epn3). Gene ontology analysis revealed several significantly enriched functional inter-relationships between genes influenced by non-obese T2DM. Protein-protein interaction analysis demonstrated that Stat is a potential key gene influenced by non-obese T2DM. CONCLUSIONS: Non-obese T2DM alters cardiac gene expression profile. The altered genes may be involved in the development of cardiac pathologies and could be potential therapeutic targets in non-obese T2DM
