2017 Plant Science Today  
The effect of salinity stress and its amelioration by pretreatment with low concentration of NaCl (50mM) on growth and sugar metabolism in arhar (cv. T120) and maskalai (cv. WBU109) seedlings were studied. Salinity was found to be more toxic for root growth than shoot growth. Fresh weight and dry weight of the seedlings gradually decreased with increasing concentrations of NaCl treatment. It was demonstrated that direct germination on NaCl solution increased both reducing sugar and non-reducing

Salinity stress also affected the activites of different sugar metabolizing enzymes. The increase in the activities of starch phosphorylase, sucrose phosphate synthase, sucrose synthase and decrease in the activities of acid invertase were observed in directly salt treated test seedlings that were altered by pretreatment with sublethal concentration of NaCl in both the cultivars arhar (cv. T120) and maskalai (cv. WBU109) seeds. Thus the application of pretreatment by sublethal concentration of NaCl in both arhar (cv. T120) and maskalai (cv. WBU109) seeds exhibited significant alteration of all the partinent parameters tested under salinity stress and the effect of pretreatment in most of the parameters were more prominent in arhar (cv. T120) with compared to maskalai (cv. WBU109) seedlings.

A total (n=100) patient aged 30 to 50 years of either sex with ASA I and II waiting for elective abdominal surgery were randomized into two equal groups. Group C (n=50) received (4μg/kg) of oral clonidine 90 minute before laryngoscopy and Group L (n=50) received 1.5 mg/kg lignocaine 3 minute before laryngoscopy as active drugs and appropriate placebos were administered as double dummy technique. Comparable demographic and baseline parameters like heart rate, systolic blood pressure and diastolic blood pressure were recorded at various time intervals. Similar anesthesia technique applied was in both the study arm. Result: Attenuation of systolic blood pressure, diastolic blood pressure, heart rate and mean arterial pressure was statistically highly significant (p<0.0001) more in Group C as compared to Group L within first vital 10 minutes of intubation. Conclusion: Oral clonidine attenuates the stress response better than intravenous lignocaine during laryngoscopy and endotracheal intubation with minimum adverse effects.

ABSTACT: BACKGROUND: Septicaemia is a life threatening complication of severely burned patients. Among many organisms invading blood stream Pseudomonas aeruginosa is a well-known for its powerful antibiotic resistance mechanisms which increasingly limit the choices for treatment. Among many such resistance mechanisms it is the metallo-beta-lactamase (MBL) which confers resistance to Carbapenem group of antibiotics, one of the final resorts to fight them. The present study was undertaken to

MATERIALS AND METHODS: For this purpose 67 Pseudomonas aeruginosa isolates from blood samples of admitted burned patients were subjected to susceptibility testing to antipseudomonal drugs by disc diffusion test and those found to be Carbapenem resistant were subjected to Imipenem -EDTA combined disk synergy test for MBL detection. RESULT: Out of 67 isolates of P.aeruginosa, 19 (28.4%) were found to be Carbapenem resistant and 11 (16.4%) were MBL producers. A particularly important feature was that the MBL producers were highly resistant to the antibiotics tested than the non-producers. However all of them were susceptible to Colistin and Polymixin B. CONCLUSION: This study has made us to think that a constant vigil and careful selection of antibiotics are necessary to keep prevalence of MBL producing P.aeruginosa in check. The accurate identification and reporting of MBL producing P. aeruginosa will aid infection control practitioners in preventing the spread of these multidrug-resistant isolates.

At the early stages of carcinogenesis, the induction of tumor specific T cell mediated immunity seems to block the tumor growth and give protective anti-tumor immune response. However, tumor associated macrophages (TAMs) might play an immunosuppressive role and subvert this anti tumor immunity leading to tumor progression and metastasis. Methodology/Principal Findings: The Cu (II) complex, (chelate), copper N-(2-hydroxy acetophenone) glycinate (CuNG), synthesized by us, has previously been

The current study demonstrates that CuNG treatment of TAMs modulates their status from immunosuppressive to proimmunogenic nature. Interestingly, these activated TAMs produced high levels of IL-12 along with low levels of IL-10 that not only allowed strong Th1 response marked by generation of high levels of IFN-c but also reduced activation induced T cell death. Similarly, CuNG treatment of peripheral blood monocytes from chemotherapy and/or radiotherapy refractory cancer patients also modulated their cytokine status. Most intriguingly, CuNG treated TAMs could influence reprogramming of TGF-b producing CD4 + CD25 + T cells toward IFN-c producing T cells. Conclusion/Significance: Our results show the potential usefulness of CuNG in immunotherapy of drug-resistant cancers through reprogramming of TAMs that in turn reprogram the T cells and reeducate the T helper function to elicit proper antitumorogenic Th1 response leading to effective reduction in tumor growth.

RESULTS AND ANALYSIS: Out of the 125 strains of GNB, 32 strains were found to be Imipenem resistant by Kirby Bauer disk diffusion, 18 (56.25%) were Pseudomonas aeruginosa, 7 (21.87%) were K.pneumoniae, 4 (12.5%) were Acinetobacter spp, 2 (6.25%) were Citrobacter and 1 (3.12%) was E.coli. When these 32 isolates were tested for MBL production by IMP+EDTA Combined disk diffusion test, 29 (90.62%) of the isolates were found to be MBL producers, by Imipenem+EDTA double disk synergy test, 26(81.25%) of the isolates showed MBL production and by MBL E-test, 30 (93.75%) of the isolates were MBL producers. CONCLUSION: From our study it appears that metallo-β-lactamase production in gram negative bacilli has become a significant problem in health care associated infection control in this part of India and is producing many carbapenemase resistant strains in India.

2005 Journal of crop and weed   unpublished
A field experiment was conducted during Boro season of 2002-2003 and 2003-2004 to study the effect of irrigation and weed management on weed growth and relative yield performance of transplanted hybrid rice. Continuoils submergence of 5±2 cm depth of water considerably reduced the weed crop competition, and increased the grain yield and decreased the dry matter production of total weeds over 3 days after disappearance of ponded water. Hand weeding twice (25 and 45 DAT) and chemical weed control

An increase in 14.75 to 24.03% grain yield was recorded due to adoption of weed management practices. · Key words: Transph1nted hybrid rice, weed management, irrigation management. Puddling followed by continuous submergence of land, effectively controls the weeds, in transplanted rice field. In rice fields, vacying soil moisture regimes are followed like continuous submergence to drier saturation. Singh and Singh (1988) recorded least weed growth and maximum crop yield under continuous submergence than drier treatments. The germination and emergence of weed seeds are closely related with the moisture status and the depth of water standing on the soil. Thus a full proof irrigation management is important for controlling weeds in transplanted hybrid rice cultivation during boro season. Irrigation management not only controlled the weed growth but also decided the efficiency of applied herbicides to the crop (Moody, 1978). Hand weeding, though laborious, expensive and time consuming one still one of the most effective method for controlling weeds in our country. However, the chemical method of weed control is better alternative and also advantageous over hand weeding particularly under intensive cropping systems. The main objective of the present investigation was to find out the effects of different water regimes and irrigation management practices on weed growth and yield of transplanted hybrid rice. MATERIALS AND METHODS A field study was carried out for two consecutive winter seasons of 2002-03 and 2003-04 at Instructional Farm, Jaguli, Nadia, West Bengal. The soil was sandy loam in texture having pH 6.8. Initially the soil was low in nitrogen, medium in phosphorus and high in potassium content. The total N(%) was 0.05 and 0.05, available P20s (Kg ha" 1) was 21.12 and 20.98 and the available K 2 0 (Kg ha" 1) was 160.28 and 161.30 during 2002-03 and 2003-04 respectively. The experiment was laid out in split plot design with water management practices in main plots and weed management in sub-plots with three replications. The hybrid rice variety Pro-Agro 6444 was grown as test crop. The treatments consisted four events of irrigation (Main) viz. 5±2 cm continues submergence (Io), 1 day after disappearance of 5 cm ponded water (11), 2 days after disappearance of 5 cm ponded water (12) and 3 days after disappearance of 5 cm ponded water (13) and four weed management practices viz. unweeded check (W o), weed free continuous weeding (W1), Pyrazo sulfuran ethyl@ 25 g a.i. ha-1 at 7 DAT (W-i), Pretilachor @ 400 g ha· 1 at 3 DAT (W 3) and Hand weeding twice at 25 and 45 DAT (Wy. The fertilizers were applied@ 120: 60: 60 kg ha· ofN, P20s and K20 respectively. Full doses of P20s and K20 were applied as basal. Nitrogen was applied half the dose during tillering stage and rest half in two equal splits at 10 days after transplanting and panicle initiation stage. Population and dry weight of weeds were recorded from 0.5 x 0.5 m 2 area from each plot at 30, 60, 90 DAT and harvest. The crop received 166.3 mm and 208.6 mm rainfall during growth period of 2002-2003 and 2003-2004 respectively. Weed control efficiency (WCE) and weed index (WI) were computed using the following standard formulae:
