| 1 | Biochemical characters and antibiotic susceptibility of Staphylococcus aureus isolates显示文摘Objective:To observe the biochemical characters and antibiotic susceptibility of isolated Staphylococcia aureus(S.auerus) strains against some conventional and traditional antibiotics. Methods:Thirty post operative pathogenic isolated S.aureus strains were used in this study. Bacterial culture was done in Mueller-Hinton broth at 37 ℃.Characters of these strains were determined by traditional biochemical tests such as hydrolysis test of gelatin,urea,galactose, starch and protein,and fermentation of lactose and sucrose.Antibiotic susceptibility were carried out by minimum inhibilory concentration test,minium bactericidal concentration test,disc agar diffusion test and brain heart infusion oxacillin screening agar.Results:Prom this study,it was observed that 100%S.aureus isolates showed positive results in gelatin,urea and galactose hydrolysis test.50%isolates were positive in starch hydrolysis test,35%in protein hydrolysis test. 100%isolates in lactose fermenting test,but no isolate was positive in sucrose fermenting test. Antibiotic susceptibility testing suggested that 20%of isolates were resistant to kanamycin and 46.67%were resistant to oxacillin.Conclusions:These findings show that all these isolates have gelatin,urea,galactose hydrolysis and lactose fermenting activity.20%of these isolates were resistant to kanamvcin and 46.67%were resistant to oxacillin. | Subhankari Prasad Chakraborty Santanu Kar Mahapatra Somenath Roy | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，3： | 5 |
| 2 | Development of flexible zinc–air battery with nanocomposite electrodes and a novel separator显示文摘In this paper, we present the development of flexible zinc–air battery. Multiwalled carbon nanotubes(MWCNTs) were added into electrodes to improve their performance. It was found that MWCNTs were effective conductive additive in anode as they bridged the zinc particles. Poly(3,4-ethylenedioxythiophene)polystyrene sulfonate(PEDOT:PSS) was applied as a co-binder to enhance both the conductivity and flexibility. A poly(acrylic acid)(PAA) and polyvinyl alcohol(PVA) coated paper separator was used to enhance the battery performance where the PVP–PAA layer facilitated electrolyte storage. The batteries remained functional under bending conditions and after bending. Multiple design optimizations were also carried out for storage and performance purposes. | Zhiqian Wang Xianyang Meng Zheqiong Wu Somenath Mitra | 2017 | Journal of Energy Chemistry2017，26，1： | 4 |
| 3 | Alpha-tocopherol supplementation on chromium toxicity: a study on rat liver and kidney cell membrane显示文摘Membrane damage is one of the important consequence of chromium, an environmental toxicant, to produce cytotoxicity. α-tocopherol, a membrane protectant can be used to reduce the chromium-induced membrane damage. In the present study, the impact of chromium in presence and absence of α-tocopherol was studied on plasma membrane of liver and kidney in male Wistar rats (80—100 g body weight). Significant increase in membrane cholesterol level as well as significant decrease in membrane phospholipid level in chromium exposed ( 0.8 mg /100 g body weight/d, i.p., for 4 weeks) animals suggest structural alteration of both liver and kidney plasma memebrane. The alkaline phosphatase, total ATPase and Na +-K +-ATPase activities of plasma membrane were significantly decreased in both liver and kidney after chromium treatment. However, α-tocopherol (30 mg/100 g diet) supplementation can restrict the changes in these membrane-bound enzyme activities. Thus, the usefulness of dietary supplementation of α-tocopherol to restrain the chromium-induced membrane damage is suggested. | Sankar Kumar Dey Prasunpriya Nayak Somenath Roy | 2003 | Journal of Environmental Sciences2003，15，3： | 4 |
| 4 | Nitric oxide mediated Staphylococcus aureus pathogenesis and protective role of nanoconjugated vancomycin显示文摘Objective:To investigate the relation between fruit seeds,plants residuals and appendicitis. Methods:Among cases that underwent appendectomy,the appendicitis cases having fruit seeds and undigested plant residuals in their etiology were examined retrospectively.Also, histopathological features,age,sex,and parameters of morbidity and mortality were used. Results:Fruit seed was found in one case(0.05%) with presence of pus in appendix lumen, undigested plant residuals in 7 cases(0.35%).It was determined that there were appendix inflammation in 2 of the plant residuals cases,while there were obstruction and lymphoid hyperplasia in the appendix lumen of 5 cases.No mortality was observed.Conclusions:The ratio of acute appendicitis caused by plants is minimal among all appendectomised patients, but avoidence of eating undigested fruit seeds and chewing plants well may help to prevent appendicitis. | Subhankari Prasad Chakraborty Santanu Kar Mahapatra Sumanta Kumar Sahu Sourav Chattopadhyay Panchanan Pramanik Somenath Roy | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，2： | 4 |

| 6 | Antioxidative effect of folate-modified chitosan nanoparticles显示文摘Objective:To evaluate the potency of carboxymethyl chitosan-2,2' ethylenedioxy bisethylamine-folate(CMC-EDBE-FA) on tissue injury,antioxidant status and glutathione system in tissue mitochondria and serum against nicotine-induced oxidative stress in mice.Methods: CMC-EDBE-FA was prepared on basis of carboxymethyl chitosan tagged with folic acid by covalently linkage through 2,2' ethylenedioxy bis-ethylamine.Animals were divided into four groups,i.e.,control,nicotine(1 mg/kg bw/day),CMC-EDBE-FA(1 mg/kg bw/day) and nicotine(1 mg/kg bw/day) and CMC-EDBE-FA(1 mg/kg bw/day) for 7 days.Levels of lipid peroxidation, oxidized glutathione level,antioxidant enzyme status and DNA damage were observed and compared.Results:The significantly increase of lipid peroxidation,oxidized glutathione levels and DNA damage was observed in nicotine treated group as compared with control group;those were significantly reduced in CMC-EDBE-FA supplemented group.Moreover,significantly reduced antioxidant status in nicotine treated group was effectively ameliorated by the supplementation of CMC-EDBE-FA.Only CMC-EDBE-FA treated groups showed no significant change as compared with control group;rather than it repairs the tissue damage of nicotine treated group.Conclusions:These findings suggest that CMC-EDBE-FA is non-toxic and ameliorates nicotine-induced toxicity. | Subhankari Prasad Chakraborty Santanu Kar Mahapatra Sumanta Kumar Sahu Panchanan Pramanik Somenath Roy | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，1： | 3 |

| 8 | Aqueous extract of Ocimum gratissimum Linn and ascorbic acid ameliorate nicotine-induced cellular damage in murine peritoneal macrophage显示文摘Objective:To test the in vitro protective role of aqueous extract of Ocimum gratissimum Linn. (0.gratissimum) and ascorbic acid against nicotine-induced murine peritoneal macrophage. Methods:Peritoneal macrophages from mice were treated with nicotine(10 mM),nicotine (10 mM) with aqueous extract of O.gratissimum(1 to 25μg/mL),and nicotine(10 mM) with ascorbic acid(0.01 mM) for 12 h in cell culture media,while the control group was treated with culture media.Levels of free radical generation,lipid peroxidation,protein carbonyls,oxidized glutathione levels and DNA damage were observed and compared.Results:Phytochemical analysis of aqueous extract has shown high amount of phenolics and flavonoids compound present in it.The significantly increased free radical generation,lipid peroxidation,protein carbonyls,oxidized glutathione levels and DNA damage were observed in nicotine-treated group as compared to the control group:those were significantly reduced in aqueous extract of O. gratissimum and ascorbic acid supplemented groups.Moreover,significantly reduced antioxidant status in nicotine exposed murine peritoneal macrophage was effectively ameliorated by these two products.Among the different concentration of aqueous extract of O.gratissimum,the maximum protective effect was observed at 10μg/mL which does not produce any significant change in the normal cell.Conclusions:These findings suggest the potential use and beneficial role of O.gratissimum as a modulator of nicotine-induced cellular damage in murine peritoneal macrophage. | Santanu Kar Mahapatra Subhankari Prasad Chakraborty Somenath Roy | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，10： | 2 |
