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

Serum glycoproteins were evaluated in oral squamous cell carcinoma patients treated with radiotherapy and also the effect
of vitamin E was studied. Cell surface glycoconjugates are important parameters in the detection of malignancy. Thus, the
objective of the present study is to evaluate the efficacy of vitamin E on glycoproteins in oral cavity cancer patients treated
with radiotherapy. The study includes 26 age and sex matched normal healthy individuals and 26 patients with squamous cell
carcinoma of oral cavity. These patients were divided into two groups, one for radiotherapy alone (at a dosage of 6000 cGy
in five fractions per week for a period of six weeks) and the other for radiotherapy plus vitamin E supplementation (at a
dosage of 400 IU / day of vitamin E) for the entire period of radiotherapy. Levels of hexose, hexosamine, fucose and sialic
acid were increased in oral squamous cell carcinoma patients and a significant decrease was observed in radiation treated
patients when compared to control. The levels of glycoconjugates were significantly decreased in radiation treated patients
supplemented with vitamin E. This measurement may be useful in assessing disease progression and identifying patients resistant
to therapy and a possible role of vitamin E on reduction in glycoconjugate levels of radiation treated oral squamous cell
carcinoma patients. 相似文献

A recent initiative or skill bridging measure taken by the Malaysian public universities is to build into the formal curriculum soft skills to produce graduates with a right balance of diverse abilities. However, to date, there is no comprehensive attempt to review the integration of soft skills in the formal curriculum (both coursework and training) of university programmes. The paper therefore reviews the adequacy of the infusion and acquisition of the entire range of skills embedded in taught courses and practical/industrial training from the students’ perspective. The specific focus of the study is to identify what worked well and what had not in acquiring the skills designated in the teaching–learning process. The key findings of the study are as follows. First, the perceived infusion–acquisition of skill types differs unequivocally between coursework and training, suggesting the complementary nature of both components of the formal curriculum for the integration of soft skills. Second, the infusion–acquisition of soft skills remains highly concentrated on specific items/skills for both coursework and training. For the coursework component, communication skills explain most of the total variance, whilst moral and professional ethics ranks first in explaining the total variance for the training component. In total, the perceived low and selective appreciation of skills by students signals the need to readdress the existing strategies within the teaching–learning process to ensure a better integration of soft skills. 相似文献

The antiulcerogenic effects of the methanolic extract ofSolanum nigrum berries (SBE) on aspirin induced ulceration in rats with respect to antioxidant status in the gastric mucosa have been investigated.
Oxygen free radicals are considered to be important factors in the pathogenesis of gastric ulcer. The level of lipid peroxides,
which were elevated highly in rats with acute gastric mucosal injury was taken as an index of oxidative stress. The activities
of antioxidant defense enzymes were also decreased considerably by oral gastric administration of aspirin. The decreased levels
of antioxidant enzymes and increased mucosal injury were altered to near normal status upon pretreatment with (SBE) when compared
to the ulcer induced rats. The results indicate that (SBE) may exert its gastroprotective effect by a free radical scavenging
action. Our observations suggest that (SBE) may have considerable therapeutic potential in the treatment of gastric diseases. 相似文献

Reading and writing deficits in twomultilingual speakers of Kannada, Hindi andEnglish are described. Disorders of the twopatients (Mr G and Ms S) had differentetiologies. Mr G had severe alexia withagraphia in English as well as in Kannada andHindi. Ms S exhibited dissociation across thelanguages, showing symptoms of surface dyslexiain English and mild dyslexia in Kannada. Bothpatients were tested on the Western AphasiaBattery and on tests developed by Coltheart.Their test performance is described anddiscussed in the context of orthographicdifferences between English and various Indianlanguages. 相似文献
