Potential Chemoprevention of 7,12-Dimethylbenz[a]anthracene Induced Renal Carcinogenesis by Moringa oleifera Pods and Its Isolated Saponin     

Veena Sharma  Ritu Paliwal 《Indian journal of clinical biochemistry : IJCB》2014,29(2):202-209

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

Teachers’ perspective on institutional barriers to academic entrepreneurship – a case of Uttarakhand state,India     

Lalit Sharma 《Teachers and Teaching》2017,23(4):436-450

The study explores the institutional factors which influence the impact of education in building academic entrepreneurship in higher educational institutes of Uttarakhand state, India. In order to understand the institutional barriers, the author interviewed 68 senior-level educationists, who were working in the capacity of Director General, Professor, Head, or Director in three different universities or their affiliated institutions. Based on the qualitative data obtained from interviews, we identified five major and four minor factors which were influencing the impact of education in building academic entrepreneurship in the state. The major barriers identified were – poor entrepreneurial ecosystem, poor entrepreneurial orientation, and inclination of universities and institutes to prepare students for jobs, inadequate content of the subject, need for training of entrepreneurship faculty, or specialized entrepreneurship faculty and ineffective teaching methodology. The results so obtained were further reviewed and validated on the basis of past research. The study also takes into account the institutional problems in developing academic entrepreneurship in other developing countries and compares the results. The study will help policy-makers, teachers, and educational institutions to recognize the possible shortfalls in the education system, which eventually result in poor academic entrepreneurship. Suggestions for improvements are included.  相似文献

External quality assessment for the RIA of thyroid related hormones: Second phase     

Ajay Kumar  D. H. Shah  M. G. R. Rajan  U. R. Thakare  S. M. Sharma 《Indian journal of clinical biochemistry : IJCB》1992,7(2):159-164

An external quality assessment was conducted to assess the performance of various laboratories for RIA of thhyroid related hormones in two phases. In the first phase thirty five laboratories participated. At the end of first phase a meeting cum workshop was organised to discuss the results of first phase, difficultires faced by the participants and pinpoint the short oming. A second phase was then initiated with an objective of improvement in the performance, if any, where twelve samples from four pools were distributed to twenty four laboratories who participated for the second phase. The overall return of the results increased significantly from 71.8% (1586/2208) for the first phase to 92.4% (732/792) for the second phase. The inter laboratory %CV for T₃, T₄ and TSH were lower during the second phase (30.6%, 19.0% and 31.6% respectively) as compared to those observed during first phase (36.3%, 22.7% and 52.8% respectively). Similarly, there was an improvement in reproducibility of ALTM as %CV for T₃, T₄ and TSH decreased from 6.0%, 9.8% and 13.4% respectively to 4.5%, 4.6% and 8.5% respectively. The individual performances of the participating laboratories viz. bias, variability of bias and imprecision also showed a trend towards improvement as percent laboratories having desirable or acceptable results for T₃, T₄ and TSH increased from 10.7%, 60.7% and 0.0% respectively to 20.8%, 66.7% and 22.2% respectively. External quality assessment thus appears to be beneficial in assessing the performane of a laboratory in comfparison with other laboratories and indeed helps in improving the performance.  相似文献   

Serum oestradiol in women with carcinomas of the breast and uterine cervix     

Amitabha Ray  Anil Kumar Bahadur  S. L. Dayalu Naik  Bhuvnesh Kumar Sharma 《Indian journal of clinical biochemistry : IJCB》2001,16(2):199-202

Endogenous oestrogens are thought to be involved in breast cancer, but few studies could show the direct relationship between hormones and pathological process of the disease. In the present study, oestradiol was estimated in the serum of pre-and postmenopausal breast cancer patients along with normal healthy controls and patients with carcinoma of the uterine cervix which is not dependent on oestrogens. Premenopausal patients with breast cancer showed higher levels of oestradiol as compared to premenopausal control women as well as cervical cancer patients. Whereas, no statistically significant differences were observed in serum oestradiol levels amongst postmenopausal groups of breast cancer, cervical cancer and normal women. The result of the study reflects the association of oestradiol as well as its difference in the pathological events of pre and postmenopausal breast cancer.  相似文献   

Medicinal plants for treatment of diabetes mellitus     

R. Shukia  S. B. Sharma  D. Puri  K. M. Prabhu  P. S. Murthy 《Indian journal of clinical biochemistry : IJCB》2000,15(1):169-177

Many plants have been used for the treatment of diabetes mellitus in Indian system of medicine and in other ancient systems of the world. Out of these only a few have been evaluated as per modern system of medicine. From many such plants only extracts have been prepared and their usefulness evaluated in experimental diabetes in animals. In some plants likeAllium cepa, Allium sativum, Ficus bengalensis, Gymnema sylvestre, Pterocarpus marsupium etc. active hypoglycemic principles have been isolated and their mechanism of action studied. Most of them seem to act directly on pancreas (pancreatic effect) and stimulate insulin level in blood. Some have extra pancreatic effect also by acting directly on tissues like liver, muscle etc. and alter favourably the activities of the regulatory enzymes of glycolysis, gluconeogenesis and other pathways. Since the plant products have less side effects, they have the potential as good hypoglycemic drugs. They may also provide clues for the development of new and better oral drugs for diabetes.  相似文献   

Serum apolipoproteins in the patients of myocardial infarction in different age groups     

R. Sharma  V. S. Singh 《Indian journal of clinical biochemistry : IJCB》2001,16(1):122-126

The level of serum cholesterol (Ch), serum-high density lipoprotein cholesterol (HDLc), serum-low density lipoprotein cholesterol (LDLc), serum very low density lipoprotein cholesterol (VLDLc), Triglyceride (Tg), Apolipoprotein A-1, B and ratio of Apolipoprotein A1/B were observed in 151 survivors of myocardial infarction in different age groups. A significant increase was found in the level of triglyceride, LDLc, apolipoprotein-B and a significant decrease in apolipoprotein-A1 and the ratio of apolipoprotein A1/B. No significant alteration was found in serum cholesterol, HDLc except in the age group of 31–40 years and 41–50 years and VLDLc. Thus, serum Apo A-1 and Apo-B may be considerably better markers for coronary artery disease than traditional lipid parameters.  相似文献
