In chronic bronchial asthma inflammation may be accompanied by intensive air flow limitation. Endogenous oxidants produced by overactive inflammatory cells destroy airway epithelium which slough into bronchial lumen and thus aggravates asthma. When oxidant overwhelm anti-oxidants, tissue injury and disease results. It is observed that decrease level of anti-oxidants in the lungs is a feature of chronic bronchial asthma and that there is a marked decrease of these levels during acute asthmatic attacks. These observations highlight the positive correlation between anti-oxidant therapy in asthmatic patients. The study was carried out to observe the changes in lung function in patients with chronic bronchial asthma both before and after supplementation of anti-oxidant vitamin A. Pulmonary function variables such as FVE, FEV1, FEV1/FVC%and PEFR were measured by spirometer in patients with chronic bronchial asthma both before and three month after supplementation of vitamin A 10,000 I.U orally daily. The mean FVC, FEV1, FEV1/FVC% and PEFR following vitamin A was unchanged significantly (P<0.001) than the pre supplementation values in patients with chronic bronchial asthma. This study reveals that no improvement of pulmonary functions occur after supplementation of anti-oxidant vitamin A in chronic bronchial asthma patients.TAJ 2014; 27(1): 10-13
Background : Screening for thyroid hormones in the newborn baby is extremely important to detect the newborns who are born with hypofunctional state of thyroid gland. This screening program in first few weeks of life is essential to prevent serious complications of hypothyroidism in future such as mental retardation. Objective : To assess the thyroid hormone levels in normal newborn and preterm, low birth weight babies and comparison of thyroid dysfunction between these two groups.Method : This cross - sectional analytical type of study was conducted in the department of physiology and paediatrics of Rajshahi Medical College & Hospital ( RMCH) from July 2015 to June 2016. A total of 70 newborn baby were enrolled by systematic sampling of which 40 were normal healthy newborn and 30 were preterm, low birth weight babies. Data was collected from the parents and they were filled out standard questionnaire. Then venous blood was collected from each and every neonate and blood was sent to laboratory for estimation of thyroid hormone levels. FT4 and TSH values were estimated as these two are the most important parameters for determination of thyroid function.Result : In this study, the mean (±SD) serum FT4 level in term and preterm neonates were 14.17±2.14 and 12.25±3.16 (pg/ml) respectively. This FT4 value is significantly higher in term neonates than preterm neonates (P< 0.05). The mean (±SD) serum TSH level in term and preterm neonates were 3.37±2.12 and 4.23±3.23 (μIU/ml) respectively. Statistically there was no significant difference in TSH values between these two groups (P≥0.05).Conclusion : From this study it was evident that preterm, low birth weight babies are more likely to develop hypofunctional state of thyroid gland than normal term babies. The newborns who were found hypothyroid, were informed to their parents for consultation with the concerned physicians. The physicians then took necessary steps to correct the hypofunctional state of thyroid gland.TAJ 2013; 26: 20-23
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
