The 85% methanolic extract obtained from the whole plant of Enicostemma littorale has been assessed for analgesic and anti-inflammatory activity. The analgesic activity has been evaluated by hot plate and tail immersion method and the anti-inflammatory and antioxidant activities are evaluated by Complete Freund’s adjuvant induced arthritic model. The results of the evaluation of analgesic activity in hot plate and tail immersion method revealed that the extract exhibits significant activity at 150 mg/kg body weight and the effect is found to increase dose dependently. In Freund’s adjuvant induced arthritis, Enicostemma littorale is found to decrease the paw volume (15.81%). Significant protection is also observed by elevating antioxidant enzymes. In conclusion, the 85% methanolic extract of Enicostemma littorale possesses significant analgesic and anti-inflammatory activities in Freund’s adjuvant induced arthritic model in rats.展开更多

The development of this disease is a relatively secret and repeated process, and therefore early diagnosis and evaluation of the disease is usually difficult. In this study, an arthritis model was successfully induced by injecting complete Freund’s adjuvant (CFA) into the toes of lower limbs of Wistar rats. Seven days after injection of CFA, obvious redness and swelling appeared at the toe joints of lower limbs accompanied by more sensitivity to thermal stimulation. Using the ultraweak bio-photon imaging system (UBIS) established by us, the toe joint area of the lower limbs of rats was imaged 7 days after injection of CFA. It was found that the volar part of lower limbs of arthritis rats showed significantly higher biophoton emissions compared with the control group. The results of this study may provide a basis for further research and devel-opment of early diagnosis and assessment of lesion progression of rheumatoid arthritis.展开更多
