Green Synthesis of AgNPs Stabilized with biowaste and their antimicrobial activities.

In the present study, rapid reduction and stabilization of Ag+ ions with different NaOH molar concentration (0.5 mM, 1.0 mM and 1.

Chemically induced skin carcinogenesis in mice and its prevention by Aegle marmelos (an Indian medicinal plant) fruit extract.

This study assessed the chemopreventive potential of the Aegle marmelos plant on mouse skin tumorigenesis initiated by 7,12-dimethylbenz(a)anthracene (DMBA) and promoted by croton oil. A significant reduction in tumor incidence, tumor burden, tumor multiplicity, and the cumulative number of papillomas, along with a significant increase in the average latent period, was recorded in mice treated orally with A. marmelos extract (AME) at peri - and post-initiation phases (i.

Ultrastructural changes in the testis and epididymis of rats following treatment with the benzene chromatographic fraction of the chloroform extract of the seeds of Carica papaya.

The benzene chromatographic fraction of the chloroform extract of the seeds of Carica papaya at a dose of 10 mg/rat/day for 150 days, which has shown a total inhibition of motility, reduced sperm count and infertility, was tested to de fi ne the mode of action at the subcellular level in the testis and epididymis. The ultrastructure of the testis of the treated animals revealed no appreciable changes in the subcellular characteristics. The mechanism of protein synthesis as well as steroidogenesis were evident in the Sertoli cells while the spermatogonia, spermatocytes and spermatids, both round and elongated, depicted a prominent nucleus, distinct nuclear membrane and cytoplasmic characteristics indicating normal germ cell differentiation.

Ultrastructural changes in the rabbit epididymis following vasectomy and clip occlusion.

Adult male rabbits were subjected to vasectomy, tantalum clip occlusion and sham operations. Caput and cauda regions of epididymis were studied with electron microscope at intervals of 15 days and 15 months after operation. Vasectomized and clip occluded subjects revealed similar changes when compared with sham operated animals.
