Abstract
BACKGROUND Viscum orientale is a largely used parasitic plant with traditional medicinal properties. They are considered to possess the medicinal properties of host tree which they grow on. It's a least explored plant with ethanopharmacological importance. As a result, the current work aimed to investigate the biological effects of Viscum orientale extract and silver nanoparticles (AgNPs) generated from it. METHODS AgNPs synthesized using Viscum orientale plant extract and analysed on time dependent series and was characterized using Ultra Violet UV-visible spectra, Fourier Transform Infrared Spectroscopy FTIR, X-ray diffraction (XRD), Energy Dispersive X-ray Spectroscopy (EDX), Scanning Electron Microscopy (SEM). Further using disc method anti-microbial assay was performed following antioxidation screening using 1,1-diphenyl-2-picryl-hydrazyl (DPPH), reducing power and nitric oxide content and heamgglutination with human blood. RESULTS On green synthesis using silver, the phyto contituents of plant Viscum orientale effectively reduced silver ions at 3-4 h of continuous stirring to form AgNPs. UV-vis spectra showed a typical peak of AgNPs at 480 nm. The FTIR analysis confirmed the covering of silver layers to bio-compounds of the extract. SEM analysis represented AgNPs as spherical morphologies ranging from 119-222 nm. AgNPs exhibited impressive zone of inhibition against Escherichia coli (8.1 ± 0.3 mm), Staphylococcus aureus (10.3 ± 0.3 mm), Bacillus subtilis (7.3 ± 0.3 mm), Bacillus cereus (8.2 ± 0.3 mm), Salmonella typhi (7.1 ± 0.2 mm). AgNps exhibited efficiency against DPPH at EC50 value of 57.60 µg/ml. and reducing power at EC50 of 53.42 µg/ml and nitric oxide scavenging of EC50 of 56.01 µg/ml concentration. Further, anthelmintic activity results showed synthesized nanoparticles significant reduction in the paralysis time to 5.4 ± 0.3 min and death time to 6.5 ± 0.6 min in contrast to the individual factors. On hemagglutination using AgNPs, above 80 µg/ml of concentration showed very significant effect on comparison with water extract. CONCLUSION Synthesized AgNPs using Viscum orientale water extract displayed versatile biological activity than individual extract. This study has forecasted a new path to explore more on this AgNPs for further research.

Modulatory effects of Crataeva nurvala bark against testosterone and N-methyl-N-nitrosourea-induced oxidative damage in prostate of male albino rats. Pharmacogn Mag 2012; 8:285-91.

Abstract
BACKGROUND Antioxidant properties of Crataeva nurvala bark contains a variety of the bioactive phytochemical constituents in medicinal plants which include flavonoids, phenolic compounds, tannins, anthracene derivatives, and essential oils. Components from Crataeva nurvala bark have been accounted to play an important role in scavenging free radicals generated by mutagens and carcinogens. Androgens are the key factors in either the initiation or progression of prostate cancer by inducing oxidative stress. In the present set of investigations, the antioxidative potential of Crataeva nurvala bark extract against androgen-mediated oxidative stress in male Wistar rats has been studied. MATERIALS AND METHODS Oxidative damage in prostate was induced in rats by the injection of testosterone (100 mg/kg body weight [bw]) for 3 days followed by injection of chemical carcinogen N-Methyl N-Nitroso Urea (50 mg/kg bw) for 1 week. The oxidative damage in prostate-induced rats were treated with the ethanolic extract of Crataeva nurvala bark (150 mg/kg bw) and testosterone injection (2 mg/ kg bw) was also continued through the experimental period of 4 months. The prostate tissue was dissected out for biochemical analysis of lipid peroxidation and enzymic-antioxidants viz. catalase, superoxide dismutase, glutathione peroxidase, glutathione-S-transferase, and glutathione reductase; the non-enzymic antioxidants viz. reduced glutathione, and Vitamin C. RESULTS The results revealed that testosterone administration induced the oxidative stress in rat prostate; however, in drug (150 mg/kg bw) supplemented groups, a significant protective effect of Crataeva nurvala bark against testosterone-induced oxidative injury was recorded. CONCLUSION Hence, the study reveals that constituents present in Crataeva nurvala bark impart protection against androgen-induced oxidative injury in prostate.

Abstract
BACKGROUND Euphorbia hirta (L.) (Euphorbiaceae) is a very popular herb amongst practitioners of traditional medicine and used in the treatment of female disorders, respiratory ailments, tumors, jaundice, digestive problems, wounds, etc. We aimed to evaluate the protective effect of E. hirta against nitrobenzene-induced nephrotoxicity in albino rats. MATERIALS AND METHODS The nephroprotective activity of the ethanol extract of E. hirta (400 mg/kg body weight) was studied in nitrobenzene-induced albino rats (1000 mg/kg body weight). The activities of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST), and the levels of reduced glutathione (GSH), total thiols and vitamin C in the kidney tissues were determined. Histopathologic investigation was performed in the kidney tissue samples. RESULTS Nitrobenzene administration significantly (P < 0.01) enhanced the lipid peroxidation and significantly (P < 0.05) depleted the levels of SOD, CAT, GPx, GST, GSH, total thiols and vitamin C. Treatment with the ethanol extract of E. hirta significantly normalized the antioxidant levels. The nephroprotective activity was also supported by histopathologic studies of kidney tissue. CONCLUSION The results indicate that the ethanol extract of E. hirta ameliorates renal dysfunction and could be used as an effective protector against nitrobenzene-induced nephrotoxicity, primarily through its antioxidant capacity.
