METHODS： Mice were administered the biologically active fraction of N J, i.e., the 4th fraction （N J4）, intra- peritoneally, and then injected with the stable chole- cystokinin analogue cerulein hourly for 6 h. Six hours after the last cerulein injection, the pancreas, lung, and blood were harvested for morphological examination,measurement of cytokine expression, and examination of neutrophil infiltration. RESULTS： N J4 administration attenuated the sever- ity of AP and lung injury associated with AP. It also reduced cytokine production and neutrophil infiltration and resulted in the in vivo up-regulation of heine oxy- genase-1 （HO-1）. Furthermore, NJ4 and its biologically active fraction, N J4-2 inhibited the cerulein-induced death of acinar cells by inducing HO-1 in isolated pan- creatic acinar cells. CONCLUSION： These results suggest that N J4 may be a candidate fraction offering protection in AP and N J4 might ameliorate the severity of pancreatitis by induc- ing HO-1 expression.展开更多

Formation of nodular outgrowth on the roots of wheat seedlings treated with 2, 4-D commenced in 8-10 days. The maximum Para-nodule formation was found in 1 ppm of 2, 4-D when incubated with bradyrhizobium P-132. Inoculation of the same has helped to increase the number of Para-nodule, but not essential for Para-nodulation. Histological study shows that, these induced Para-nodules originated from the pericycle and these are appeared to be modified lateral roots and Para-nodule structure formations however, it enhanced by bradyrhizobial inoculation.展开更多
