A CORRELATIONAL STUDY BETWEEN VOCABULARY MASTERY AND READING COMPREHENSION AT ECONOMIC FACULTY OF ALKHAIRAAT UNIVERSITY

This research is a correlational study with two variables – variable X standing for vocabulary mastery and variable Y standing for reading comprehension. There were three research questions: (1) What is the level of correlation between variable X and variable Y; (2) How significant is the contribution that can be given by variable X toward variable Y; and (3) Is there positive correlation between variable X and variable Y? The sample of this research was fifty students of the first semester at Economic Faculty of Alkhairaat University. The instruments were tests and questionnaire. Through tests, it was found that: (1) The level of correlation between variable X and variable Y was strong; (2) The significant contribution given by variable X toward variable Y was 52.8%, meaning variable X gave much contribution to variable Y; and (3) There was positive correlation between variable X and variable Y since the value of r-counted (0.727) was higher than the value of r-table (0.279). Through questionnaire, 46% respondents agreed that vocabulary took a role in helping them to comprehend English texts, meaning the more vocabulary they have, the better they are in comprehending English texts.

Effect of Supplementation of Vitamin E in Combination of Selenium on the Immune Status of Human Subjects Against Tuberculosis

Tuberculosis is one of the leading causes of mortality in Pakistan which is linked with malnutrition and weak immunity. Such people are more prone to chronic infections including TB. The current study aimed to assess the effect of supplementation of Vitamin E on the immune status of human subjects against pulmonary tuberculosis. A total of 80 patients with pulmonary TB were divided into treatment group (vitamin E) and control group (Anti-tuberculosis regime). Presence of acid fast bacilli in sputum sample, Erythrocyte sedimentation rate, total leucocytes counts, body mass index and mid arm muscle circumference (MAMC) were recorded as per standard protocol. Levels of vitamin E, IgG, IgM and T-Cell count were determined before and after treatment. The results showed that 16% males and 33% females were underweight who consumed 1145 kcal energy instead of 2270 kcal per day and 19.5 gram protein instead of 78.6 grams. A non significant effect of vitamin E on ESR and TLC values was observed but significant increase in level of immunoglobulins (IgG, IgM) and T-cell types (CD4+ and CD8+) was observed in patients as compared to control group. Results indicate that vitamin E plays important role in enhancing immunity of patients against TB.
