The purpose of this study was to determine the effect of water and hexane soluble fractions of the Indian medicinal plant, Solanum trilobatum on the nonspecific immune mechanisms and disease resistance in Oreochromis mossambicus. Fish were intraperitoneally injected with different doses of 0, 4, 40 or 400 mg kg(-1) body weight of water or hexane soluble fraction. The nonspecific immune mechanisms were assessed in terms of serum lysozyme activity, reactive oxygen species production and reactive nitrogen species production by peripheral blood leucocytes. The functional immunity in terms of percentage mortality and Relative Percent Survival (RPS) was assessed by a challenge with live Aeromonas hydrophila. Almost all the doses of both water and hexane soluble fractions enhanced the serum lysozyme activity. All the doses of water soluble fraction significantly enhanced the ROS production on most of the days tested. In hexane soluble fraction treated groups, the enhancement in the ROS production was observed at least on 2 days. All the doses of water soluble fraction significantly enhanced the production of RNS only on one day. The RNS production was enhanced significantly only in the group treated with 40 mg kg(-1) of hexane fraction. The leaf fraction administration preceding the challenge with live A. hydrophila, decreased the percentage mortality in the experimental group with the consequent increase in RPS values. This preliminary study indicates that S. trilobatum could be used to promote the health status of fish in intensive finfish aquaculture.

Terminalia belerica Roxb. fruits have been previously reported against diabetes, ulcer, microbial problems and hepatotoxicity. The present study was aimed to investigate antioxidant and anticancer potential of sequentially fractionated hexane (TBHE), chloroform (TBCE), ethyl acetate (TBEE), butanol (TBBE) and water (TBWE) extracts from the 70% methanolic extract of T. belerica fruits. TBCE, TBEE, TBBE and TBWE showed excellent ROS (reactive oxygen species) and RNS (reactive nitrogen species) scavenging activities which was investigated using 11 different assays for various free radicals. Among 5 fractions, TBHE and TBCE remained nontoxic to any of the malignant cell lines including normal cells (WI-38). TBBE and TBWE inhibited the proliferation of breast (MCF-7), cervical (HeLa) and brain (U87) cancer cells by inducing G2/M arrest while TBEE caused apoptosis. However, these fractions did not inhibit the proliferation of lung (A549) and liver (HepG2) cancer cells. BrdU incorporation study also suggested the efficient anticancer potential of TBEE, TBBE and TBWE. Moreover, TBBE and TBWE treated MCF-7, HeLa and U87 cells showed upregulation of p53 and p21 proteins. Phytochemical analysis reflected the presence of adequate quantities of different phytochemicals. Moreover, HPLC analysis show peaks of purpurin, catechin, tannic acid, reserpine, ellagic acid, methyl gallate, aconitine and rutin in TBBE, TBWE and TBEE. Hence these polar extracts of T. belerica can be used to develop drug against different types of cancer.
