Filariasis is a major health problem, affecting millions of people in tropical and sub-tropical regions of the world. The isolation and characterization of parasite-specific enzyme targets is essential for developing effective control measures against filariasis. Acetylcholinesterase (AchE, E.C. 3.1.1.7), an important enzyme of neuromuscular transmission is(More)
Presently available marketed alum adsorbed hepatitis B vaccine used for prophylactic immunization, can effectively elicit humoral immunity but is poor inducer of cell-mediated immunity (CMI). Besides, conventional alum-adjuvant vaccines require multiple injections to achieve long-lasting protective immune responses. Therefore, as a result of insufficient(More)
The present investigations were aimed to compare the humoral and cell-mediated immune responses between recombinant hepatitis B surface antigens (HBsAg) adsorbed L-PLA microspheres (Ms) vaccine (single-shot) and marketed alum-HBsAg vaccine (two-doses). The blank cationic (cetyltrimethyammoniumbromide) microspheres were prepared by the double emulsion(More)
There is increasing interest in phytoestrogens as potential alternatives to synthetic selective estrogen receptor modulators (SERMs) in the prevention and therapy of breast cancer. The present study is aimed at determining whether dietary glycine soya (Glycine max seeds; GS), which is rich in phytoestrogens, can enhance the anti breast cancer efficacy of(More)
The fate of intraperitoneally inoculated infective third-stage larvae (L3) of the nematode Brugia malayi Lichtenstein and the status of the peritoneal macrophage function were investigated in the susceptible rodent hosts Mastomys natalensis Roberts and Meriones unguiculatus Milne-Edwards (jird). Jirds and M. natalensis were inoculated intraperitoneally with(More)
Lymphatic filariasis, onchocerciasis, loaisis, and other helminth infections cause serious health problems especially in resource-limited tropical and subtropical developing countries of the world, and more than 2 billion people are infected with at least one helminth species. From times immemorial, man looked up to the plant kingdom in search of(More)
As part of our drug discovery program for anti-filarial agents from Indian medicinal plants, leaves of Eucalyptus tereticornis were chemically investigated, which resulted in the isolation and characterization of an anti-filarial agent, ursolic acid (UA) as a major constituent. Antifilarial activity of UA against the human lymphatic filarial parasite Brugia(More)
BACKGROUND & OBJECTIVE Lymphatic filariasis is a disabling disease that continues to cripple population in tropical countries. Currently available antifilarial drugs are not able to control the disease. Therefore, a better antifilarial is urgently required for proper management of the disease. We undertook this study to assess the antifilarial activity of(More)
