Membrane hydrophobicity and slalidase activity of normal Poly morphonuclear Leucocyte were significantly enhanced when incubated with DSF. As a consequence, internalisation ofE. coli andS. aureus (opsonised or unopsonised) were greatly dimnished, internalisation ofE. coli being higher in either category. Although, increase in hydrophobicity of the membrane correlated well with the time of decrease of particle internalisation (both at 30 min.), enhancement of sialidase activity did not coincide with the said alterations. 相似文献

Present investigation shows that hydroethanolic extract of Moringa oleifera (MOHE) and its isolated saponin (SM) attenuates DMBA induced renal carcinogenesis in mice. Isolation of SM was achieved by TLC and HPLC and characterization was done using IR and 1H NMR. Animals were pre-treated with MOHE (200 and 400 mg/kg body weight; p.o), BHA as a standard (0.5 and 1 %) and SM (50 mg/kg body weight) for 21 days prior to the administration of single dose of DMBA (15 mg/kg body weight). Administration of DMBA significantly (p < 0.001) enhanced level of xenobiotic enzymes. It enhanced renal malondialdehyde, with reduction in renal glutathione content, antioxidant enzymes and glutathione-S-transferase. The status of renal aspartate transaminase, alanine transaminase, alkaline phosphatase and total protein content were also found to be decreased along with increase in total cholesterol in DMBA administered mice. Pretreatment with MOHE and SM significantly reversed the DMBA induced alterations in the tissue and effectively suppressed renal oxidative stress and toxicity. 相似文献

With increasing student migration for Higher Education to Karnataka, it is important to understand the reasons which influence the migrants. Studies have indicated various push and pull factors for migration. This paper identifies career opportunities, value for education, brand equity, living conditions and others as pull factors of student migration using exploratory factor analysis. Further, the paper develops a structural equation model using a partial least square technique based on the factors explored. The research is based on primary data collected from students who migrated to Karnataka for Higher Education. The partial least square structural equations model shows that job opportunities and academic progression are the main factors influencing the decision to migrate to Karnataka. 相似文献

This paper aims to explore the discrepancy between self-reported and test-based literacy estimates in Bangladesh. It uses
the Education Watch national literacy survey data of 2002, during which the literacy status of a nationally representative
sample was identified using the two methods referred to above. The findings revealed that the literacy rate generated through
a literacy test was significantly lower than that found when the self-report method was used. The level of discrepancy varied
from one population group to another, indicating that literacy assessment using the self-report method cannot be equally appropriate
for all population groups. Those with a few years of schooling were at a particular risk of over-estimating their status.
The paper makes a case for a written literacy assessment rather than an oral evaluation. 相似文献
