Preparation of extracts and preliminary phytochemical screening Aqueous extract was prepared by cold maceration. Drugs and chemicals Carrageenan was procured from Sigma Chemical Co. Acute toxicological evaluation To assess the acute toxicity of MJL determination of LD 50 value of the aqueous extract was attempted using the up-and-down method as described by Bruce.
Evaluation of invivo anti-inflammatory activity and grouping of animals Carrageenan-induced paw edema model Paw edema was induced[ 19 ] by injecting 0. Formalin-induced paw edema model The animals were treated in the same way as in above model except that formalin 0. Anti-inflammatory activity Table 1 shows the effect of aqueous extract of leaves and standard drug as compared to carrageenan control at different hours in carrageenan-induced paw edema model using vernier caliper.

Omega-3 fatty acids and antioxidants in edible wild plants. Biological research. Edema formation, leukocyte infiltration and granuloma formation represent typical features of inflammation. Non-steroidal anti-inflammatory drugs NSAIDs , steroidal drugs, and immune- suppressant drugs, which have been usually used in the relief of inflammatory diseases worldwide for a long time, are often associated with severe adverse side effect, such as gastrointestinal bleeding and peptic ulcer.
Inflammation is defined as the local response of living mammalian tissues to injury due to any agent. It is a body defense reaction to eliminate or limit the spread of injurious agent as well as necrosed cells.
Acute inflammation can be conventionally described as a vascular and cellular event. In vascular events, alterations include hemodynamic changes such as transient vasoconstriction, persistent progressive vasodilatation, followed by local hydrostatic pressure, stasis, lucocytes migration and vascular changes in which accumulation of edema fluid. In cellular events, phagocytosis, that is engulfment of solid particulate material by cells, causes the inflammation.
Chronic inflammation causes tissue destruction brought by activated macrophages by release of variety of biological active substances. It would appear that the extracts had a suppressive effect on these events. Inflammation plays a major role in most chronic illnesses, including neurodegenerative, cardiovascular, pulmonary, metabolic, autoimmune and neoplastic diseases. Herbal medicines derived from plant extracts are being increasingly utilized to treat a wide variety of clinical disease, though relatively little knowledge about their mode of action Correspondence is available.
There is a growing interest in pharmacological evaluation of various plants used Ranajit Kumar Khalua in Indian traditional system of medicine. Tha British pharmacist Stanford in The name was later plants were identified and authenticated by the dept.
Each has their own gel commercially from enlisted supplier of Vidyasagar University characteristics which are all thermally reversible. The lambda and maintained in standard laboratory conditions. They were from does not gel strongly at room temperature and is given standard laboratory diet and water ad libitum. All injectable to induce an inflammatory response. Inflammatory induced by carrageenan is acute, nonimmune, well- animal experiments are approved by the University Animal researched, and highly reproducible.
Cardinal signs of Ethics Committee, dept. Such agents can be generated in situ at the site of insult or by infiltrating cells. The shade. It was then crushed and taken in a round-bottomed inflammatory response is usually quantified by increase in flask with distilled water and refluxed in a water bath for 1 paw size edema which is maximal around 5 hours hour at degree centigrade. The supernatant obtained postcarrageenan injection.
The development of edema in the were combined and filtered through a whatman No. The filtrate was concentrated at low temperature by release of histadin, serotonin and prostaglandin like lyophilization.
The residue obtained was designated as substances. According to an estimate made by the WHO aqueous extract. Recently many natural medicines The plant parts of Alstonia scholaris Linn, Swertia chirata, divided from plants, marine organism, etc. The extract will bark of A. In t5he present study, inhibitory effects of the aqueous extracts of A.
The mortality rate within a 24 hours period will be determined according to the method described by Miller Table 1: Groups in the present of study and Tainter.
Rats of group II were supplier. Acute paw edema was paw diameter of control and drug treated animals. The results induced by injecting 0. After 1 hour, 0. The linear paw Results of anti-inflammatory activity were expressed as mean circumference will be measured at hourly interval for 3 h. The significance of difference perimeter of paw was measured by using screw gauge.

Inflammation is a severe response by living tissue to any kind Although active inflammatory compound have already been of injury. There can be four primary indicators of reported from these plants, the study emphasizes on the inflammation: pain, redness, heat or warmness and swelling. This gives a raised indomethacin.
Vasoactive chemicals also increase the permeability increase pore size Reference of these arterioles which allows blood cells, chemicals 1. Effect of insulin region.
