Secondary school library plays a significant role to support the school course curriculum. However, national policy or strategy for secondary school library is yet to be formulated in Bangladesh. The present study made an effort to propose a strategy for secondary school library in Bangladesh, to review and re-envision its functions and services. This strategy will act as a guideline for a librarian and secondary school authorities. Based on the present status of secondary school library in Bangladesh, the present study also focuses on the significance, organizational structure, obstacles and possible outcomes of this strategy.

The present study was conducted to evaluate the antipyretic, anti-inflammatory and membrane stabilizing, antioxidant, thrombolytic, anti-diarrheal activities of Scindapsu shederaceus belonging to the Araceae family. In antipyretic test, temperature reduced from 101.53°F to 99.86°F (p<0.05), 99.20°F (p<0.05) and 99.06°F (p<0.05) in 1 st , 2 nd and 3 rd hour, respectively and caused maximum reduction of temperature in 1 st hour. In the hot plate method, the extract increased the reaction time of heat sensation significantly to 14.32 seconds. In in vitro anti-inflammatory test, the extract significantly inhibited protein denaturation by 85.17% at 500 µg/ml, 71.72% at 250 µg/ml and by 66.55% at 125 µg/ml. It also inhibited the hypotonic solution-induced haemolysis by 73.19%, 49.69% and 29.15% at same concentration in membrane stabilizing assay. In DPPH inhibition assay the extract showed maximum % inhibition of 65.5% at 100 µg/ml. In the assay of thrombolytic activity, the extract showed thrombolytic activity of 14.39%. Amylase inhibitory activity was found to be 22.38% at a concentration 100 µg/ml. In case of antidiarrheal investigation, the extract reveled total inhibition of defection by 35.30%.
