Climate change is considered to be one of the most serious threats and its impact is felt by the most vulnerable world's poorest countries including Bangladesh. In particular, ethnic communities, whose livelihoods depend on the use of natural resources, are likely to bear the brunt of adverse impacts. A case study was conducted in a fragile ecosystem of Lawachara national park of Bangladesh, to know the indigenous knowledge of the ethnic communities, how they adapt with the climate change impact by using indigenous knowledge. They use various IK to protect their crops from climate change impact. Thus, government should design policies which will be helpful to make them more resilience to face climate change impact.

Traditional medicinal practitioners or Kavirajes use a variety of medicinal plants for treatment of thrombus ailments-cardiovascular problems. In this study, thrombolytic activity of 36 extracts of different solvents of eight Bangladeshi medicinal plants traditionally used in cardiovascular problems were evaluated to justify their use in folklore medicinal practitice. Extraction was conceded using methanol. Five grams of the concentrated methanol extract of each crude extract were then fractionated to provide n-hexane and carbon tetrachloride fractions. Phytochemically important groups like reducing sugars, tannins, saponins, steroids, gums, flavonoids and alkaloids were tested using standard chromogenic reagents. In vitro thrombolytic potential of extracts was assayed for analyzing the clot lyses by adding the extracts to the pre-clotted blood. The results were compared with the results obtained from streptokinase as standard and water as a negative control. Thrombolytic effect of the extracts ranged from 0.73 ± 2.44 % to 45.81 ± 0.34 % clot lysis whereas the standard streptokinase showed 65.13 ± 0.96 % and the negative control water showed 2.50 ± 0.67 % clot lysis. The highest thrombolytic effect was shown by the crude extract of Melastoma malabathricum leaves and the lowest by the CCl4 fractionate of Litsea glutinosa leaves. Most of the results were found relevant to the traditional use of the plants. Plants traditionally used in thrombus ailments may be an interesting source for further drug development.
