The hypocholesterolemic effect of the water extract of the bark ofFicus bengalensis was investigated in 3 groups of rabbits, 5 in each group. Group 1 rabbits served as healthy controls and were fed with groundnut oil 1 ml/kg body wt. (bw) for five weeks. Groups 2 and 3 were made hypercholesterolemic by feeding orally cholesterol suspended in groundnut oil (1 ml/kg bw) at a dose of 100 mg/kg bw/day. Group 2 animals (untreated) continued to get the same amount of cholesterol for another four weeks. Group 3 animals received water extract of the bark (50 mg/kg bw/day) in addition to cholesterol as above. At the end of the 5th week, water extract not only prevented the elevation of serum cholesterol in the treated animals (Group 3) but also brought down its level to 160±14 mg% as compared to untreated animals (Group 2) 290±42 mg%. There was improvement in other parameters of lipid profile namely HDL & LDL+VLDL cholesterol and triacylglycerol. 相似文献

Usually CPK, CK-MB and lactate dehydrogenase (LDH) enzymes are measured in blood during the period of myocardial infarction.
The changes in LDH assay indicates duration of the infarction.
The level of lactate dehydrogenase is 500 times greater in tissue than those found in serum. A small mass of damaged tissue
causes leakage of enzyme and increases its level in serum.
Any cause of tissue break down/hemolysis which is sufficiently severe can produce LDH pattern similar to that in myocardial
infarction.
We report this case of small bowel volvulus showing significant increase in LDH.
It may be due to tissue necrosis which increases the level of LDH in serum. 相似文献

The hepatoprotective potential of earthworm extract (EE) (Lampito mauritii, Kinberg) was evaluated against paracetamol-induced liver injury in Wistar albino rat, in comparison with silymarin, the standard hepatoprotective drug. We observed a reduction in liver antioxidants, such as glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (GPx),and catalase (CAT) and in serum total protein, and an increase in serum alkaline phosphatase (ALP), serum aspertate aminotranferase (AST), serum alanine aminotranferase (ALT), bilirubin and liver thiobarbituric acid reactive substances (TBARS) due to liver injury in the paracetamol-administered rats (2 g/kg). On the contrary, increased activities of liver GSH, SOD, GPx,CAT and serum total protein level, and decrease in the contents of serum ALP, AST, ALT, bilirubin and liver TBARS were observed in rats administered with different doses of EE (100, 200 and 300 mg/kg), which are similar to the activities of hepatoprotective drug silymarin (150 mg/kg). The mode of action of EE as evidenced by the above parameters may suggest that EE, on the one hand, prevents the formation of the reactive oxygen groups, or scavenges these groups, thereby preventing the damage on the hepatic cells, and, on the other hand, modulates the genes responsible for synthesis of antioxidant enzymes such as GPx, CAT and SOD in liver tissue and decreases the serum enzymatic activities such as ALP, AST and ALT. 相似文献

To effectively help urban pre-service teachers to provide civic education opportunities in their future classrooms, teacher educators should know how urban pre-service teachers themselves conceptualize citizenship and civic engagement. Through the research question—how do urban K-6 pre-service teachers currently enrolled in an urban education teacher certification program at a 4-year university construct key concepts and ideologies about citizenship and civic education?—we examined how 15 pre-service teachers understood these concepts. Using three conceptions of citizenship—personally responsible citizen, participatory citizen, and justice-oriented citizen (Westheimer and Kahne in Am Educ Res J 41(2):237–269, 2004)—our analysis demonstrated that urban pre-service teachers’ conceptions of their students’ lives significantly influenced their ideas about civic education in elementary schools. Although the participating pre-service teachers overwhelmingly promoted personally responsible citizenship, we found the participants to heavily weigh developmentally appropriate practice and classroom context when considering the risks and rewards of promoting justice-oriented citizenship in elementary classrooms. 相似文献

This investigation compared the impacts of 2‐year and 4‐year colleges on learning orientations. Controlling for precollege learning orientations, academic aptitude, age, work, place of residence, and enrollment status, this study found no significant differences between 2‐ and 4‐year students in freshman‐year effects on enjoyment of diversity and intellectual challenge, learning for self‐understanding, internal locus of attribution for academic success, and preference for higher order cognitive activities. The findings are consistent with other recent evidence casting doubt on major differences in the net educational effects of 2‐ and 4‐year colleges. 相似文献

Low serum vitamin D level has an increased association with risk of multiple sclerosis (MS).There has been no published data on the levels of this vitamin in Indian population with MS. Hence we decided to undertake this study to document if there is evidence of vitamin D deficiency in patients with MS in our population. 26 patients with diagnosis of MS by modified Mc Donald’s criteria were enrolled in this study. Serum vitamin D (1,25 hydroxy) levels were measured by electro-chemiluminescence in our biochemistry lab. An age-matched control group of 202 patients who did not have a diagnosis of MS were included. In our study group 76.9 % had vitamin D level less than 20 ng/ml compared to 65.5 % of control group (p value of 0.019). Our study revealed a trend towards low vitamin D values in Indian MS patients. 相似文献

This paper proposes a simple method to evaluate batsmen and bowlers in cricket. The idea in this paper refines ??book cricket?? and evaluates a batsman by answering the question: How many runs a team consisting of same player replicated eleven times will score? 相似文献
