ESTABLISHMENT OF A MECHANISM OF POLYHERBAL FORMULATION FOR ANTI-RHEUMATISM
Keywords:Ortho, Adjuvant induced arthritis, Carrageenan, Histamine
Objective: A marketed product Dr. Ortho has been used by many patients and is gaining a positive feedback from the patients. A study is designed to establish its mechanism of action on various anti-rheumatic models in experimental animals. No studies have been investigated on this product for its anti-rheumatic activity.
Methods: Dr. Ortho (55 mg/kg, p. o.) was administered during adjuvant-induced arthritis, phlogistic agents (Histamine, bradykinin, and serotonin) induced paw edema, Acetic acid induced writhing test in mice, and Eddy's hot plate. Histopathology (T. S. of knee joint) and various hematological parameters (WBC's, RBC's, and ESR count) were observed during the study.
Results: Dr. Ortho decreases arthritis induced inflammation by antagonizing or inhibiting the inflammatory mediators, i.e., histamine, 5-hydroxy tryptamine and bradykinin. (20% (P<0.05) of carrageenan, 10.01%, (P<0.05) of histamine, 8% (P<0.05) of 5-hydroxy tryptamine induced paw volume). Dr. Ortho acts as both peripheral and central analgesic. Histopathology findings revealed that there is a reduction in the neutrophil infiltration, pannus formation, and bone. Hematological parameters show that Dr. Ortho decreases the elevated level of the WBC's count.
Conclusion: The present study revealed some facts regarding the mechanism of Dr. Ortho in reducing arthritis induced inflammation. However study may be done further to illustrate its complete mechanism.
