Phagocytic migration. Tissue repair.PowerPoint Presentation: Mechanism of Inflammation The process of inflammation is initiated by cells present in tissue. On activation cells release mediators. Cells Mastocytes Histocytes Macrophases Dendritic cells Kupper cell. Cell derived Mediators 1.Prostaglandin 2.Histamines 3.Leukotrienes 4.TNF- α IL Plasma derived Mediators Bradykinin Thrombin Plasmin FibrinPowerPoint Presentation: Significance & Disorders of Inflammation SIGNIFICANCE. Disposal of microbes, toxins or foreign materials. Preparation of site for tissue repair. Isolation of affected area of body. Disorders Asthma Autoimmune diseases Chronic inflammation Glomerulonephritis Hypersensitivity Rheumatoid arthritis Pelvic inflammatory disease Transplant rejectionPowerPoint Presentation: Anti-inflammatory AgentsPowerPoint Presentation: Membrane phospholipid Arachidonic acid Prostaglandins Cyclo oxygenase(COX) Anti inflammatory drugs (-) Phospholipase A Any chemical and mechanical stimuli Leukotriene Lipo oxygenase (LOX) Anti inflammatory drugs (-) (-) Mechanism of action of Anti-inflammatory Drugs Screening of Antiinflammatory : Screening of Antiinflammatory In-vivo method Edema assay Erythema assay Granuloma method a) Implantation of cotton wool pellet. b) Granuloma pouch.

MOA Quercus ileus ( Fagaceae ) Leaves Kaemferol-di coumaroyl-glycoside -- Populus tremula (Salicaceae) Leaves Salicin COX inhibitorsQuercus iteus L.: Quercus iteus L. Family: Fagaceae Part : Leaves Active ConstituentS: Kaemferol-di coumaroyl-glycoside Screening: Croton oil induced dermatitis Dose dependent anti edematous effect at the time of maximal edematous response of control Anti-edematous effect during entire observation period. It is about 4 times more active than indomethacin & its activity is much more prolonged .PowerPoint Presentation: FLAVONOIDS Quercetin, Morin, Olenolic acid, Ursolic acid, Glycyrrhetic acid & Caffeine sufficiently suppress TPA-induced ear edema. LOX inhibitors, quercetin, kaempferol & baicalein, inhibit ear edema development much more markedly than COX inhibitor, paeonol. Of the various flavonoids, flavones and flavonol inhibit inflammation. In flavonols & flavones of same type, flavonol derivatives show greater inhibition than flavone derivatives. Flavanone & catechin have no effect. A double bound at C-2 & C-3 of flavonoid structure is prerequisite . Flavonoid having oxygen functions at 5, 7 & 4’ like Apigenin & Kaempferol type are more avtive than other type.PowerPoint Presentation: GLYCOSIDESGLYCOSIDES: GLYCOSIDES Species & Family Part C.C.

Biological differences between two bisbenzyl-isoquinoline may have important application for SAR & drug designing.PowerPoint Presentation: TETRANDINE Inhibitory effects on a number of inflammatory cells. Suppress the release\activity of inflammatory cytokinin, histamin as well as lipid mediators. inhibit the production of TNF- α by MNL. Broad spectrum antiinflammatory activity. If the reports of its apparent lack of toxicity in therapeutic doses are confirmed, tetrandine may serve as an important prototype compound for the development of a new class of antiinflammatory agent the treatment of rheumatoid arthritis and other chronic inflammatory diseases.
