Allergic conjunctivitis is the most common allergic disease. These diseases are severe & frequent which requires search of new treatments. The aim of the study was to investigate the effects of Tinospora cordifolia (TC), Rubia cordifolia Linn. (RC) on experimentally induced allergic conjunctivitis in rats. In this study, dried water soluble extracts of TC and RC. (250 and 500 mg/kg, p.o. for 7 days) were evaluated for their antiallergic activity in Wistar rats. They were tested for inhibition of egg albumin-induced vascular permeability, inhibition of histamine release from the rat conjunctiva as well as in histamine content in tears. TC and RC showed significant (P < 0.05) inhibition in vascular permeability, inhibition in histamine release from the rat conjunctiva which is reflected by reduced level of histamine content in tears. The activities were found to be comparable to azelastine hydrochloride. These results suggest that the inhibitory effect on egg albumin-induced experimental allergic conjunctivitis in rat may be due to the antihistaminic activity of TC and RC. Our studies provide evidence that TC and RC may be beneficial in the treatment of allergic conjunctivitis. Allergic conjunctivitis is the most common allergic disease.

Hesperidin improves warm ischemia/reperfusion-induced oxidative renal injury in rats

Ischemia/reperfusion injury, which is commonly seen in the field of renal surgery or transplantation, is a major cause of acute renal failure. Previous studies showed that antioxidant treatments attenuated renal ischemia/reperfusion injury. The objective of this study was to examine the role of hesperidin in modulating reactive oxygen species induced inflammation and apoptosis after renal ischemia/reperfusion injury. Rats were subjected to right nephrectomy, 15 days later 45 min of renal ischemia and 24 h reperfusion with or without treatment with hesperidin. Renal function, inflammation and apoptosis were compared at 24 h after reperfusion injury. Hesperidin improved the renal dysfunction and reduced inflammation and apoptosis after ischemia/reperfusion injury. In conclusion, hesperidin shows potent anti-apoptotic and antiinflammatory properties due to antioxidant property. These findings may have major implications in the treatment of human ischemic acute renal failure.
