1Molecular basis for identification of species/isolates of gastrointestinal nematode parasites显示文摘Gastrointestinal(GI) parasitism is the most serious constraint throughout the world in small ruminants which causes significant production loss in animals.GI parasites are major contributor to reduce productivity in terms of meat,milk and wool in animals.Control of GI parasite is done primarily by anthelmintic treatment where choice and schedule of treatment is done after identification and quantitation of individual parasite.Identification of GI parasites is done through microscopic method by identifying specific morphological characteristics of egg and larva(L3).Since most of parasite eggs are having similar morphological characteristics, identification up to species level through microscopy is not possible in most of cases.To address this issue,molecular techniques are the viable alternative for identification of species as well as molecular level differences within a species(isolates) of parasites.Different DNA based molecular techniques viz.PCR,AFLP,RAPD,RFLP,PCR-SSCP,real time PCR,DNA microarray etc.have been used for identification and to assess the genetic diversity among parasite population.For identification of species,the characteristic sequence of genomic DNA of different species should differ to allow the delineation of species,but at the same time,no/minor variation within the species should exist.In contrast,for purpose of identifying population variants(strains/isolates), a considerable degree of variation in the sequence should exist within a species.Various target regions,including nuclear ribosomal DNA(rDNA),mitochondrial DNA(mtDNA) or repetitive DNA elements(microsatellite loci),which show considerable variation in the number of repeats within individuals have been employed to achieve the identification of parasites species or strain.Ahmed M Singh MN Bera AK Bandyopadhyay S Bhattacharya D 2011Asian Pacific Journal of Tropical Medicine2011,4,8:6

3Biosynthesis of silver nanoparticles by using mangrove plant extract and their potential mosquito larvicidal property显示文摘Objective:To identify the larvicidal activities of silver nano particles synthesised with Rhizophora mucronata(R.mucronata) leaf extract against the larvae of Aedes aegypti(Ae.aegypti) and Culex quinquefasciatus(Cx.quinquefasciatus).Methods:In vitro larvicidal activities such as LC50 and LC90 were assessed for the Ae.aegypti and Cx.quinquefasciatus larval species.Further, characterisation such as UV,XRD,FTIR and AFM analysis were carried out for the synthesised silver nano particles.Results:The LC50 value of the synthesised silver nano particle was identified as 0.585 and 0.891 mgg/L for Ae.aegypti and Cx.quinquefasciatus larvae respectively. Further,the LG90 values are also identified as 2.615 and 6.291 mg/L for Ae.aegypti and Cx. quinquefasciatus species respectively.The synthesised silver nanoparticles have maximum absorption at 420 nm with the average size of 60-95 nm.The XRD data showed 20 intense values with various degrees such as 37.10°,47.66°,63.97°and 70.01°.The FTIR data showed prominent peaks in(3 426.89,2 925.49,2 869.56,2 346.95,1 631.49,1 031.73,669.18 and 455.12) different ranges.Conclusions:The biosynthesis of silver nanoparticles with leaf aqueous extract of R. mucronata provides potential source for the larvicidal activity against mosquito borne diseases.M Gnanadesigan M Anand S Ravikumar M Maruthupandy V Vijayakumar S Selvam M Dhineshkumar AK Kumaraguru 2011Asian Pacific Journal of Tropical Medicine2011,4,10:4
4Healing property of the Piper betel phenol, allylpyrocatechol against indomethacin-induced stomach ulceration and mechanism of action显示文摘AIM: To evaluate the protective activity of allylpyrocatechol (APC), the major antioxidant constituent of Piper betel, against the indomethacin-induced stomach ulceration in the rat model and correlates with its antioxidative and mucin protecting properties. METHODS: Male Sprague-Dawley rats were divided into five groups. Normal control rats (group Ⅰ) were given the vehicle oral dose of gum acacia in distilled water (1 mL per rat); ulcerated control and treated rats (groups Ⅱ-Ⅴ) were given a single dose of indomethacin (30 mg/kg body wt.); group Ⅱ rats were sacrificed 4 h after indomethacin administration; groups Ⅲ-Ⅴ rats were given the vehicle (1 mL per rat) or APC (2 mg/kg body wt.) or misoprostol (1.43 μg/kg body wt.) once daily by oral intubation for 7 d starting from 4 h after the indomethacin administration. After 7 d, the stomach tissues were excised for histological examination and biochemical analysis. RESULTS: Treatment with APC (2 mg/kg body wt per day) and misoprostol (1.43 μg/kg body wt per day) for 7 d could effectively heal the stomach ulceration as revealed from the ulcer index and histopathological studies. Compared to the zero day ulcerated group, treatment with APC and misoprostol reduced the ulcer index by 93.4% and 85.4% respectively (P < 0.05). Both APC and misoprostol accelerated ulcer healing observed in natural recovery (P < 0.05), their respective healing capacities not being significantly different. The healing capacities of APC and misoprostol could be attributed to their antioxidant activity as well as the ability to enhancethe mucin content of the gastric tissues. Compared to the ulcerated untreated rats, those treated with APC and misoprostol showed near normal MDA levels, while the protein levels were 86% and 78% of the normal value respectively (P < 0.05). Likewise, both APC and misoprostol increased the SOD, catalase, and mucin levels significantly (P < 0.05), the effect of APC being better. CONCLUSION: APC can protect indomethacin-induced gastric ulceration due to its antioxidative and mucin protecting properties.S Bhattacharya D Banerjee AK Bauri S Chattopadhyay SK Bandyopadhyay 2007World Journal of Gastroenterology2007,13,27:4
