Liposomes can be used to enhance delivery of drugs to brain tumors and increase therapeutic effect. The therapeutic effect may arise from release of drug from liposomes extravasated in discrete regions of the tumor vasculature and the extravascular space.

Objective: To evaluate anti-arthritic potential of methanolic extract of rhizome of Costus speciosus Koen. Methods: The powdered drug was extracted with 80% methanol. The crude extract was subjected to phytochemical investigation and was evaluated for its anti-arthritic potential by freund's complete adjuvant induced arthritis model in adult wistar albino rats. Determination of different parameters like arthritic score, arthritic index, paw thickness, body weight, and pain, altered liver enzymes and biochemical estimation like, nitric oxide level and Plasma TNF-α level was done. Finally, radiological estimation and histopathology of tibio tarsal joints was performed. Statistical analysis was performed using one way ANOVA followed by Dunnet's test at different p-values. Results: Phytochemical study revealed the presence of flavonoids, phenolic compound, saponins and carbohydrates. For different parameter mentioned above, anti-arthritic activity shown by prophylactic high dose test extract (200 mg/kg) was as potent as standard drug Indomethacin (10 mg/kg). The effect of Prophylactic low dose extract (100 mg/kg) and therapeutic high dose extract (200 mg/kg) was less than that of Indomethacin (10 mg/kg). Furthermore, Therapeutic low dose extract (100 mg/kg) was not effective. Conclusions: The obtained results indicate that Costus speciosus rhizome extract possess significant anti-arthrtic potential.

Religious fundamentalism in the South Asian region has assumed serious proportions in the last few decades. Sri Lanka, India Pakistan and to some extent Bangladesh face this problem. It is therefore necessary to examine this problem in detail.The question that crops up is what is religious fundamentalism? Why does it get aggravated so as to express itself violently. At the same time the difference between ethnicity and religious fundamentalism too should be clarified. Thus we first come to the issue of ethnicity. Ethnicity, anthropologists and Sociologists maintain, is a feeling of primordial identity with one’s social religious, linguistic or cultural group.
