Belimbing wuluh (Averrhoa bilimbi L.) pada umumnya digunakan sebagai penambah cita rasa makanan dan obat tradisional untuk mengobati peradangan, sariawan, batuk, demam, encok, perdarahan rektum wasir. Penelitian secara in vivo vitro terhadap belimbing menunjukkan adanya aktivitas antiinflamasi, namun belum dilaporkan senyawa aktif yang berperan dalam antiinflamasi tersebut. ini bertujuan mengan...

The effect of endogenous glucocorticoids on the expression of the cyclooxygenase enzyme was studied by contrasting cyclooxygenase expression and prostanoid synthesis in adrenalectomized and sham-adrenalectomized mice with or without the concurrent administration of endotoxin. Peritoneal macrophages obtained from adrenalectomized mice showed a 2- to 3-fold induction in cyclooxygenase synthesis a...

Lipopolysaccharide is an inflammatory agent and interleukin-1 is a cytokine. Their pro-inflammatory effects may be mediated by prostanoids produced by inducible cyclooxygenase-2. The aim of this study was to determine the prostanoids produced by lipopolysaccharide and interleukin-1 stimulated enterocytes through the cyclooxygenase-1 and 2 pathways. Cultured enterocytes were stimulated with lipo...

Inhibition of cyclooxygenase-2 (COX-2) has been extensively studied as an approach to reduce proinflammatory markers in acute brain diseases, but the anti-neuroinflammatory role cyclooxygenase-1 (COX-1) inhibition rather neglected. We report that m-terphenylamine derivatives are selective COX-1 inhibitors, able block microglia inflammatory response and elicit a neuroprotective effect. These com...

Prostaglandins are important mediators of renal physiology and disease. The main enzyme which governs the synthesis of prostaglandins is cyclooxygenase (COX), also called prostaglandin endoperoxide synthase (PGS). Until recently it was assumed that only one cyclooxygenase gene and protein exists, an enzyme which is now called cyclooxygenase-l (COX-I) or the 'constitutive' isoform. Between 1989a...

In an osteoblastic cell line, MC3T3-E1, cloned from mouse calvaria, epinephrine stimulated the production of prostaglandin E2 as an essentially sole arachidonate metabolite (Kusaka, M., Oshima, T., Yokota, K., Yamamoto, S., and Kumegawa, M. (1988) Biochim. Biophys. Acta. 972, 339-346). Western and Northern blot analyses showed increases in the enzyme protein and mRNA of fatty acid cyclooxygenas...

PURPOSE The aim of this study was to evaluate the expression of cyclooxygenase-2 in human breast cancer using immunohistochemistry and to determine whether the expression of cyclooxygenase-2 is associated with clinicopathological factors in invasive ductal breast carcinoma. METHODS Cyclooxygenase-2 expression was investigated by immunohistochemistry in 30 invasive ductal breast carcinoma spec...
