The purpose of this study was to evaluate antistress activity of roots of Diospyros malabarica (Desr.) Kostel (DMDK) against anoxia stress tolerance, chemical induced stress, swimming endurance stress and immobilisation stress models in mice and rats. Ethanolic extract of roots of DMDK (EERDMDK) was screened for its antistress activity at 125 mg/kg, 250 mg/kg, 500 mg/kg, p.o. doses and diazepam was selected as reference standard at 2 mg/kg i.p. dose. Stress was induced by anoxia stress tolerance, chemical induced, swimming endurance and immobilisation stress models in mice and rats. The antistress activity was evaluated by measuring anoxia stress tolerance time, number of writhes, immobility time, organs weight of animals and estimating biochemical parameters such as glucose, cholesterol and blood urea nitrogen. Pretreatment with EERDMDK showed significant increases in anoxia stress tolerance time and significant decreases in number of writhes and immobility time in mice and this effect was dose dependent when compared to control. In immobilisation stress model pretreatment with EERDMDK showed significant reduction in level of biochemical parameters...

Cancer is a major health problem; almost thought – out the world. Herbal medicines have a vital role in the prevention and treatment of cancer. The present study, the in vitro anticancer activity of Calophyllum inophyllum ethanolic leaf extract was evaluated in MCF-7 Breast cancer cell lines. Anticancer activity was evaluated with MTT standard colorimetric assay against MCF-7 cells with IC50 value of 120µg/mL. The biologically active metabolites were identified and quantified by a GC-MS method shows presence of 11 different bioactive compounds. The cytotoxic effect was found to be concentration dependent. Increased concentration of the leaf extract showed increased...

Although the antioxidant and thrombolytic potential of the “super fruit” pomegranate has been well established and documented in in vitro models, its efficacy in an animal model has not been recognised. Therefore in the present study, the aril and rind of Punica granatum were scrutinized for their role in clot lysing competence in a thrombus induced rat model. Visual manifestation, coagulation time parameters and the level of the thrombotic factors confirmed the thrombolysis. The extracts were compared with the standard drug streptokinase that was administered in...

Background: Malaria is a serious parasitic health problem in India. Plasmodium vivax and falciparum pose the greatest public challenge in endemic areas. P. vivax accounts for more than half of all malaria cases. Accurate and prompt diagnosis is not only important to prevent morbidity, but also helps minimizing drug resistance. Aim: To know the profile of malaria parasite in the patients attending UPRIMS&R, a tertiary care center in Western Uttar Pradesh. Methods: A total 26,939 samples were subjected to smear microscopy (thin and thick) or rapid diagnostic tests. Result: 1330 positive malaria cases were detected. Malaria cases were maximum in year 2010. The proportion of P.vivax, P.falciprum and mixed malaria parasites was found 67% (891 out of 1330), 32% (420 out of 1330) and 1% (19 out of 1330) respectively. Conclusion: There is a decline in trend of malaria cases in India. The highest load of malaria cases was found in month September. P. vivax is still a predominant malaria...

Pollinosis is one of the most common allergic diseases in Asia, Central and Northern Europe as well as in North America. Several proteins in parthenium pollen have already been characterized as allergens causing sensitization and the development of allergic symptoms in atopic individuals. Glutathione-S-transferase are a phylogenetically widespread enzyme family mainly involved in cellular detoxification processes and have already been described as allergens in house dust mite and German cockroach. However, no data about the role of parthenium-GST in plant pollen allergy were available so far, for this purpose we evaluated its immunological and biochemical features. In biochemical assays b-GST was not enzymatically active, whereas p-GST demonstrated high enzymatic activity. In summary, IgE antibodies level did not show significant raise after incubation neither in the VT20 nor in the Bet v1 group while significant raise is observed with IgG antibodies. No cross-reactivity between p-GST-specific Abs and b-GST was observed. In contrast, GST-specific IgG clearly recognized GST in...
