Antioxidant activity of ethanol extract of rhizome ofPicrorhiza kurroa on indomethacin induced gastric ulcer during healing

Oral administration of ethanol extract of the rhizome ofPirorhiza kurroa at a dose of 20mg/kg body weight, for 10 consecutive days, was found to enhance the rate of healing on Indomethacin-induced gastric ulcer in rats, compared to the ulcerated group without treatment. The level of peroxidised lipid, in terms of thiobarbituric acid reactive species (TBARS), in gastric tissue, was increased in ulcerated rats which was restored to near normalcy on treatment with ethanol extract. The specific activity ofin vivo antioxidant enzymes, viz SOD and catalase and total tissue sulfhydryl (thiol) group, which were markedly decreased in ulcerated group, were found to be significantly elevated (p<0.05), on treatment with the above extract, at the specified dose, compared to the indomethacin—induced ulcerated group without any supporting treatment. The present study thus suggests that the ethanol extract of rhizome ofPicrorhiza kurroa, at the dose of 20mg/kg body weight, accelerated the healing of stomach wall of indomethacin induced gastric ulcerated rats by anin vivo free radical scavenging action.     

Mindfulness in education at the intersection of science,religion, and healing

This paper investigates mindfulness as a case study of a ‘subjective turn’ in education reflecting a postsecular age. The practice of mindfulness originates in an ancient Buddhist teaching prescribed as part of the path to enlightenment. In spite of its origins, it is becoming widespread within diverse secularly conceived social and educational settings. The paper offers a historical review of this phenomenon and analyzes why and how mindfulness has become the spearhead within a burgeoning ‘contemplative turn’ in education. The thesis suggested is that ‘normal education’ follows ‘normal science’, yet science itself is now being shaken by its own venturing into the ‘dangerous’ waters of the religious experience. The paper reflects critically on the prices and merits of mindfulness in education as a practice shaped by its becoming measurable. It locates these processes as depicting the postsecular age’s blurring of boundaries between religiosity/secularity/education, subject/object, and science/healing/education.
