Effect of arogh—A polyherbal formulation on the marker enzymes in isoproterenol induced myocardial injury     

S. Suchalatha  C. S. Shyamala Devi 《Indian journal of clinical biochemistry : IJCB》2004,19(2):184-189

To study the protective role of Arogh on isoproterenol induced myocardial damage in rats. The effect of Arogh pretreatment on isoproterenol induced myocardial damage was assessed by studying the levels of lipid peroxides and changes in the activity of marker enzymes such as creatine kinase, lactate dehydrogenase and transaminases in serum and heart tissue. In isoproterenol administered rats, a significant decrease was observed in the activity of marker enzymes in the heart with a corresponding increase in their levels in serum. Lipid peroxide levels increased significantly in the serum and heart. In rats pretreated with arogh, the level of lipid peroxides and the activity of marker enzymes were maintained at near normal values. Pretreatment with Arogh offered a protective effect against isoproterenol induced myocardial damage in rats as evidenced by LDH isoenzyme patterm and histopathological studies of heart tissue.  相似文献   

BMD and Serum Intact Osteocalcin in Postmenopausal Osteoporosis Women     

Jagtap VR  Ganu JV  Nagane NS 《Indian journal of clinical biochemistry : IJCB》2011,26(1):70-73

India seems to have the highest prevalence of osteoporosis. With growing awareness of osteoporosis and its impact on life span especially in India, special attention is being paid to early detection, management and treatment of postmenopausal osteoporosis in women. Measurement of BMD and osteocalcin are of value in estimating bone turnover rates. The aim of this study is (1) to measure the specific, sensitive bone formation marker such as osteocalcin and BMD in postmenopausal osteoporosis women and postmenopausal non-osteoporosis women; (2) the follow up study to evaluate the impact of specific antiresorptive therapy (alendronate + calcium + vitamin D) regimen in postmenopausal osteoporosis by assaying osteocalcin and BMD. Sixty clinically diagnosed postmenopausal osteoporosis patients and 60 normal subjects (postmenopausal non-osteoporosis women) were recruited as control. Mean bone mineral density T score and Z score was significantly decreased (P < 0.001) in postmenopausal osteoporosis patients as compared to controls. Highly significant increase in the mean score of BMD—T score and Z score from baseline to post therapy of 3 months was observed in postmenopausal osteoporosis women. Serum osteocalcin levels were significantly increased (P < 0.001) as compared to control group. Serum osteocalcin levels were decreased significantly (P < 0.001) from baseline to post therapy of 3 months in postmenopausal osteoporosis women. BMD is the best quantifiable predictor of osteoporotic fracture and osteocalcin is specific, sensitive, promising, currently used marker for better prognosis of osteoporosis and for monitoring responses to antiresorptive therapy.  相似文献   

英语语言学硕士论文中因果类话语标记语的使用情况调查——基于语料库的研究     

杨玉洁 《科教文汇》2011,(35):93-94,126

因果类话语标记语在硕士论文一类的学术文章写作中起到不可小觑的作用。根据自建的学习者语料库和本族语者语料库的对比分析,本研究主要的发现是：（1）中国英语专业研究生在毕业论文中对因果类话语标记语的使用频率和种类要高于本族语者;（2）中国英语专业研究生过多使用表结果的因果类话语标记语,过少使用表原因的因果类话语标记语（for除外）。分析表明,共有四方面原因造成了上述差异,即语外因素、语内因素、问题意识的缺乏和个体差异。  相似文献   

谈谈汉语会话中“不是”的语法化     

闫建设 《齐齐哈尔师范高等专科学校学报》2014,(5):68-70

“不是”通常被看作一个否定词,不过它在日常会话中已经演变出了标记话语的功能。从否定词“不是”到话语标记语“不是”是一个语法化的过程。从话语标记语“不是”在语音上所表现出的特征及其组成成分“不”和“是”之间的关系来看,它的语法化可以与“是”进一步语法化为词内成分放到一起研究,可以看成是“是”字词汇化的结果之一。  相似文献   

利用元话语对广告标语中人称指示语的研究     

吴艳丽  任再新 《海外英语》2014,(12)

很多学者对广告标语的研究颇有兴趣,有学者从应用语言学和功能语言学的角度对广告标语中的人称指示语进行了研究,但是几乎找不到从元话语的角度来研究广告标语的文章。因此,该研究尝试应用元话语理论来对广告标语中的人称指示语进行分析,所选取的510条广告标语均来自网站。对第一人称、第二人称和第三人称指示语分别进行统计,然后应用元话语中的自我提及语和涉入语来对其中的第一人称和第二人称指示语进行具体分析。研究结果发现第二人称指示语出现的频率最高,其次是第一人称指示语,而第三人称指示语出现的频率远远低于第一人称和第二人称指示语。同时,在具体语境中,包括听话人的we（inclusive）被划分为涉入语,而自我提及语的I也可能充当涉入语的作用。因此,研究认为元话语的划分离不开其所处的具体语境,这对理解和翻译含人称指示语的广告语有着重要启示。  相似文献   

关系标记对汉语复句层次关系识别的影响     

吴锋文 《渭南师范学院学报》2014,(9):68-73

关系词语对计算机的汉语复句层次关系识别具有重要意义。伪关系词的出现和关系标记的缺失给复句层次关系识别造成的影响,分析复句关系词语与同形的异类词、异构词之间的区别,揭示关系标记与词间连词、篇章关系词的不同用法的差异,挖掘复句关系标记缺失的隐现形式,以期为复句层次关系识别服务。  相似文献   

“现在”：由时间标记到话语标记     

李宗江 《浙江教育学院学报》2014,(4):62-65

“现在”作为时间名词,可以指称与说话并行的时间,与“过去”或“将来”相对。但在现代汉语中最常见的用法是充当时间关系连接成分,连接分句、句子或语段;同时还具有话语标记功能,包括作为结果标记和程序转换标记。  相似文献   

口语中“这个”的语义弱化及话语标记用法     

李峰 《唐山师范学院学报》2014,(4):12-14

本文试图从使用频率的角度来说明词语本身语义弱化的原因,通过口语语体和书面语体的统计对比,发现“这个”在口语语体中出现的频数远远高于书面语体,而话语标记正是其语义弱化的一个产物。在口语语体中,“这个”还有话语标记功能,即引发话轮和延展话轮。  相似文献   

话语标记You know的话语功能分析     

李桔元  李鸿雁 《重庆师专学报》2006,5(6):59-62

话语标记（discourse markers）是国外会话分析、语用学研究的一个新领域。从会话互动和认知推理的角度对话语标记you know的话语功能进行了研究，结论认为它是多功能的，包括隐含推理功能、人际功能、话语修正功能和话语管理功能。这几种功能是相互联系的，后三者几乎可以从隐含推理功能中找到解释。  相似文献   

A Comparative Study of Bone Scan Findings and Serum Levels of Tumor Marker CA15-3 in Patients with Breast Carcinoma     

Meera S. Ghadge  Purva P. Naik  Bijaynath P. Tiwari  Ruprekha M. Hegde  Tanaji J. Matale 《Indian journal of clinical biochemistry : IJCB》2012,27(1):97-99

Breast cancer is one of the most frequent malignancies in the world. Available staging procedures to detect breast cancer are bone scan, chest X-ray, liver ultrasonography, computerized tomography, estimation of tumor markers like carbohydrate antigen (CA15-3) and carcino embryonic antigen. These procedures are expensive and may not be required in all cases. Out of 70 patients studied, 55 had normal CA15-3 and 15 had elevated levels of Ca15-3. Eight (14.5%) of the 55 patients with normal CA15-3 had abnormal bone scan. Fifteen patients had CA15-3 levels above the normal range and among these 9 (60%) had abnormal bone scan. While prime facie it would appear that a high level of CA15-3 correlate with abnormal bone scan, it is also true that the numbers are small at present and conclusions about the validity of CA15-3 as marker of bone metastasis may be premature.  相似文献
