Ecological governance in rural areas: Finnish approaches and practices

Along with the development of rural areas, rural ecological issues caused by inappropriate anthropogenic activities have not been drowned in the contexts of global environmental problems. The acceleration of rural development in developing countries would result in a series of potential threats to the deteriorating environment, if no effective governance strategies were applied. The significance of ecological governance...

Evaluation of antiemetic effect of aqueous rhizome extract of Cynodon dactylon against all emetogenic stimuli

This study was an extension of our previous antiemetic work. Many researchers quoted Cynodone dactylon as anti emetic agent but none of them have provided strong pharmacological evidence for it, which drove us for its therapeutic evaluation. Crude aqueous rhizome extract of C. dactylon was evaluated for anti-emetic activity. Emesis was induced by the oral administration of copper sulphate, fresh aqueous extract of...
