Nanocomposites were prepared by blending soy protein isolate with different percentage of MMT by melt extrusion technique. The nanocomposites were characterized by using, XRD, TEM, SEM and TGA methods. The XRD studies indicated the absence of diffraction peaks for the bio-nanocomposites. From the TEM studies it was ascertained that the degree of exfoliation increased with increase in MMT content. The morphology of the nanocomposites was ascertained from the SEM studies. The degradation pattern of the nano-composites was evaluated from the TG analysis. The drug delivery system of the nanocmposites was investigated by blending the nanocomposites with ofloxacin at different pH media. The various kinetic parameters were evaluated and the mechanism of drug delivery has been postulated based on the kinetic data.

Journal of Reproduction and Contraception 2011年第1期22卷 37-44页

Objective To evaluate male antifertility activity of hydroalcoholic extract of Ficus racemosa bark. Methods Swiss male mice were orally administered hydroalcoholic extract of Ficus racemosa bark （50 mg/kg for 30 d and 100 mg/kg body weight for next 30 d）, and the effect of the treatment on body weight, reproductive organs weight, sperm, biochemical profile （sialic acid in epididymis and fructose in seminal vesicle）, fertility and vaginal contraceptive efficacy was investigated. Recovery studies were also performed. Results Extract reduced fertility to 70% within 60 d. Suppression of cauda epididymis sperm count, motility, viability and abnormal morphology was observed. Marked reduction was noted in the weight of reproductive organs and the level of sialic acid in epididymis and fructose in seminal vesicle. Vaginal application of bark extract exhibited 80% vaginal contraceptive efficacy. After cessation of plant extract treatment, the altered parameters recovered after 60 d. Conclusion Clinical assessment of male antifertility agents should include acceptability, safety and efficacy during and after the treatment. The above results revealed the potential, reversible male antifertility effect of hydroalcoholic extract F. racemosa bark.
