Objective: Knema attenuata (Myristicaceae), popularly known as “wild nutmeg,” is an endemic tree species from Western Ghats, which has been used in folk medicine. Conventionally, the stem bark of K. attenuata is used for treating inflammatory conditions without any scientific information available for the same. The present study was undertaken to evaluate the anti-inflammatory activity of the ethanolic stem bark extract (ESBE) of K. attenuata using in vivo and in vitro screening models. Methods: The ethanolic extract of stem bark was prepared by soxhlation, and its cytotoxicity in RAW 264.7 cell line was assessed using MTT assay method. In vivo anti-inflammatory effect of extract was estimated in rats using carrageenan-induced paw edema model and cotton pellet-induced granuloma model. The in vitro anti-inflammatory activity of the extract was evaluated by cyclooxygenase and lipoxygenase inhibition assay, estimation of myeloperoxidase activity, and determination of cellular nitrite levels in lipopolysaccharide-stimulated RAW 264.7 macrophage cells. Results: Toxic symptoms were not observed for the ESBE. The extract demonstrated significant anti-inflammatory activity in both in vivo and in vitro models. The anti-inflammatory action exhibited by the extract was a result of the inhibition of leukocyte migration and nitric oxide pathway and partially by inhibition of mediators such as prostaglandins and leukotrienes. Conclusion: Findings from the study provide the evidence for the popular use of stem bark extract of K. attenuata as a potential anti-inflammatory agent.

Objective: Mesuaferrea L is a medicinal plant belongs to the family Clusiace, it is extensively used in folk medicine for treatment of chronic inflammatory diseases.The present study was aimed to evaluate in vitro and in vivo anti-inflammatory activity of M. ferrea L. Methods: The in vitro anti-inflammatory activities such as nitric oxide, PGE2, pro-inflammatory cytokines (TNF-α and IL-1β) were studied in RAW 264.7 cells and in vivo studies were carried out on carrageenan -induced inflammation in Wistar rats. The sequentially extracted M. ferreaL bark extracts (MFBHE, MFBEE, and MFBME) exhibited inhibitory effects on pro-inflammatory mediators such as nitric oxide, prostaglandin E2, tumour necrosis factorαandinterleukin-1βproduction in concentration dependent manner in LPS induced RAW 264.7 cells andCarrageenan induced paw oedema in Wistar rats. Conclusion: The result of the present study indicated that M. ferrea L ethyl acetate bark extract exhibited significant in vitroand in vivoanti-inflammatory activity.

Objective: Dietary curcumin and capsaicin are well known for their health beneficial potencies. The current study was done to assess the anti-inflammatory activity of curcumin, capsaicin and their combination by employing in vitro and in vivo models.Methods: We investigated the protective effect of curcumin, capsaicin and their combination using in vitro heat induced human red blood cell (HRBC) membrane stabilisation, in vivo 3% agar induced leukocyte mobilisation and acetic acid induced vascular permeability assay.Results: Curcumin, capsaicin and their combination exhibited concentration dependent protective effect against heat-induced HRBC membrane destabilisation, while combined curcumin and capsaicin restored 87.0±0.64 % membrane stability and it is found to be better than curcumin, capsaicin and diclofenac sodium (75.0±0.25. 72±0.9 and 80.0±0.31 %) protective effect. In agar suspension induced leukocyte mobilization assay, the combined curcumin and capsaicin had shown 39.5±1.58 % of inhibition compared to individual curcumin and capsaicin, which showed moderate inhibition of 16.0±3.14 and 21.6±2.17 % respectively. Besides, the combined curcumin and capsaicin had shown highly significant inhibition of acetic acid-induced vascular permeability in rats (62.0±3.14 %), whereas individual curcumin and capsaicin showed moderate inhibition of vascular permeability with 36.0±2.41 and 43.0±1.92 % respectively.Conclusion: This study demonstrates the significant anti-inflammatory property of combined curcumin and capsaicin at half of the individual concentration of curcumin and capsaicin.

: In vivo and in vitro studies reveal that ursolic acid (UA) is able to counteract endogenous and exogenous inflammatory stimuli, and has favorable anti-inflammatory effects. The anti-inflammatory mechanisms mainly include decreasing the release of histamine in mast cells, suppressing the activities of lipoxygenase, cyclooxygenase and phospholipase, and reducing the production of nitric oxide and reactive oxygen species, blocking the activation of signal pathway, down-regulating the expression of inflammatory factors, and inhibiting the activities of elastase and complement. These mechanisms can open up new avenues for the scientific community to develop or improve novel therapeutic approaches to tackle inflammatory diseases such as arthritis, atherosclerosis, neuroinflammation, liver diseases, kidney diseases, diabetes, dermatitis, bowel diseases, cancer. The anti-inflammatory activity, the anti-inflammatory mechanism of ursolic acid and its therapeutic applications are reviewed in this paper.
