Current investigations were carried out for the validation of in-vitro anti-inflammatory and anti-arthritic property of leaves of Skimmia anquetilia using red blood cells membrane stabilization and protein denaturation methods respectively. Defatted ethylacetate extracts at different concentration levels (50, 100, 200 and 400 mg/ml) were used in these studies. Dose dependent inhibition of protein denaturation was found 92.41% at 400 mg/ml of extracts and 96.21 % at 100 mg/ml of acetyl salicylic acid as standard in antiarthritic study. Similarly, in membrane stabilization methods, maximum effect found 90.70 % at 400 mg/ml of extracts and 94.88 % at 100 mg/ml of diclofenac sodium as standard for anti-inflammatory evaluation. The results concluded that, ethyl acetate extract of S. anquetilia leaves has shown significant (*aP<0.05) anti-inflammatory and anti-arthritic effects.

Objective: The objective of this study was to evaluate the anti-inflammatory and antiarthritic potential of Parmelia perlata. Methods: The relative study is based on in vitro anti-inflammatory and antiarthritic activity using hydroalcoholic extract of P. perlata (HAEPP). The preliminary phytochemical tests showed the presence of various phytochemical compounds such as alkaloids, flavonoids, and glycosides since the lichen species of P. perlata has the folklore claim of anti-inflammatory activity, thus it was studied by human red blood cells membrane stabilization method, and arthritic activity was carried using protein denaturation method using diclofenac as a standard.Results: The results showed eminent anti-inflammatory and antiarthritic activity in a dose-dependent manner. The membrane stabilization showed the maximum effect at 78.54% at the concentration of 1000 μg/, and the protein denaturation was also found maximum at 1000 μg/ml concentration at 79.43%. Thus, our research states the potent anti-inflammatory activity and antiarthritic effect in P. perlata. Conclusion: The HEAPP has a potent anti-inflammatory activity and antiarthritic activity. A further study has to be conducted to establish the pharmacological evidence behind the compound and the mechanism of action of the HAEPP on the inhibition of the inflammation process.

The present research work aimed at evaluating the anti-inflammatory activity of Zingiber officinalis with Diclofenac sodium by HRBC membrane stabilization & Protein denaturation. The precluding of hypotonicity induced HRBC membrane lysis was taken as a measure of the anti-inflammatory activity. The percentage of membrane stabilization at different concentrations was performed for methanolic, hydro-methanolic ginger extract and diclofenac sodium. At a dose of 50µg/ml the maximum membrane stabilization 86.34% was found for Ginger extract(test) and at a dose of 500 mcg/ml membrane stabilization was found 91.16% for diclofenac sodium(standard) and the membrane stabilization for combination (ginger with diclofenac sodium) at a dose of 50µg/ml was recorded 86.43%, as the concentration increase(1000 mcg/ml) for combination(ginger with diclofenac sodium) the percentage protection was decreased. In vitro protein denaturation was performed by using egg albumin method. Maximum inhibition was observed in case of methanolic extract of ginger at concentration 1000mcg/ml and it was 78.83±5.17 and in hydro methanolic extract for Diclofenac sodium at concentration 1000mcg/ml and it was 63.37±2.78.Minimum inhibition observed in combination of methanolic extract of ginger and diclofenac sodium at concentration 1000mcg/ml and it was 25.27±1.76 and in combination of hydro-methanolic extract of ginger and Diclofenac sodium at concentration 1000mcg/ml and it was 28.23±3.14. The results of this study divulge that low dose combination of ginger and diclofenac sodium has higher anti-inflammatory activity than diclofenac sodium and ginger alone. With this initial study, research work could be extended further; therefore, the particular pharmacological action for the combination of ginger with diclofenac sodium could be discovered.

Objective: The present study was carried out to investigate the in vitro anti-inflammatory activity of syringic acid (SA).  Methods: SA was tested for it's in vitro anti-inflammatory activity at different concentrations in protein denaturation, proteinase inhibition and human red blood cell (HRBC) membrane stabilization assay. The reference drugs used were aspirin and diclofenac sodium. Results: SA showed concentration-dependent inhibition of protein denaturation and proteinase activity with a half-maximal inhibitory concentration (IC50) value of 49.38±0.56 µg/ml and 53.73±0.27 µg/ml respectively. Heat-induced haemolysis was inhibited by SA with an IC50 value of 57.13±0.24 µg/ml. SA also inhibited the hypotonicity-induced haemolysis (IC50 value of 53.87±0.72 µg/ml). Conclusion: From the present study, we can conclude that SA possesses appreciable anti-inflammatory effect against denaturation of proteins, proteinase activity, and human red blood membrane stabilization assays. Further studies are required for determining the possible mechanisms behind its anti-inflammatory action.

Byttneria pilosa is locally known as Harijora, and used by the native hill-tract people of Bangladesh for the treatment of rheumatalgia, snake bite, syphilis, fractured bones, elephantiasis and an antidote for poisoning. The present study was carried out to determine the possible anti-inflammatory, analgesic, neuropharmacological and anti-diarrhoeal activity of the methanol extract of B. pilosa leaves (MEBPL) through in vitro, in vivo and in silico approaches. In the anti-inflammatory study, evaluated by membrane stabilizing and protein denaturation methods, MEBPL showed a significant and dose dependent inhibition. The analgesic effect of MEBPL tested by inducing acetic acid and formalin revealed significant inhibition of pain in both tests. During the anxiolytic evaluation, the extract exhibited a significant and dose-dependent reduction of anxiety-like behaviour in mice. Similarly, mice treated with MEBPL demonstrated dose-dependent reduction in locomotion effect in the open field test and increased sedative effect in the thiopental sodium induced sleeping test. MEBPL also showed good anti-diarrheal activity in both castor oil induced diarrheal and intestinal motility tests. Besides, a previously isolated compound (beta-sitosterol) exhibited good binding affinity in docking and drug-likeliness properties in ADME/T studies. Overall, B. pilosa is a biologically active plant and could be a potential source of drug leads, which warrants further advanced study.

Despite many efforts, the control of reproduction in feral cat populations is still a problem in urban regions around the world. Immunocontraception is a promising approach; thus the present study examined the suitability of the widely used pig zona pellucida proteins (pZP) for contraception in feral domestic cats. Purified zona pellucida proteins obtained from pig and cat ovaries were used to produce highly specific antisera in rabbits. Antibodies against pZP raised in rabbits or lions were not effective inhibitors of either in vitro sperm binding (cat spermatozoa to cat oocytes) or in vitro fertilization in cats, whereas antibodies against feline zona pellucida proteins (fZP) raised in rabbits showed a dose-dependent inhibition of in vitro fertilization. Immunoelectrophoresis, ELISA and immunohistology of ovaries confirmed these results, showing crossreactivity of anti-fZP sera to fZP and to a lesser extent to pZP, but no interaction of anti-pZP sera with fZP. It is concluded that cat and pig zonae pellucidae express a very small number of shared antigenic determinants, making the use of pZP vaccine in cats questionable. A contraceptive vaccine based on feline zona pellucida determinants will be a better choice for the control of reproduction in feral cats if immunogenity can be achieved.

ABSTRACTThein vitroactivity of a novel group of compounds, hexaazatrinaphthylene derivatives, against two species ofLeishmaniais described in this study. These compounds showed a significant dose-dependent inhibition effect on the proliferation of the parasites, with 50% inhibitory concentrations (IC50s) ranging from 1.23 to 25.05 μM against the promastigote stage and 0.5 to 0.7 μM against intracellular amastigotes. Also, a cytotoxicity assay was carried out to in order to evaluate the possible toxic effects of these compounds. Moreover, different assays were performed to determine the type of cell death induced after incubation with these compounds. The obtained results highlight the potential use of hexaazatrinaphthylene derivatives againstLeishmaniaspecies, and further studies should be undertaken to establish them as novel leishmanicidal therapeutic agents.
