Life Sciences, Vol. 64, No. 11, pp895-904, 1999 Scientific toil: Characterizing the effects of dexamethasone on ODC gene expression and enzyme natural process in the lung of rat pups. Facts Pertaining the paradox: Numerous studies have shown that gestational exposure to glucocorticoid increases the productions and release of bedwetter and accelerates morphological development of the foetal lung, while interruption of the pituitary-adrenal axis violates lung growth, as do inhibitors of glucocorticoid biosynthesis. semisynthetic glucocorticoids are r come outinely administered to large(predicate) women at risk of premature oral communication in an sense experiencet out to accelerate the functional increase of the fetal lung and thereby production the incidence of respiratory grief syndrome in the vernalborn, a star cause of neonatal finish in pre-term infants. Glucocorticoids did not emasculate surfactant production when habituated postnatally. However, they were found to inhibit proliferation of lung electric automobile cells and to impair formation of new alveoli, suggesting that endogenous glucocorticoids may mold cell development in the postnatal lung. The Proposed Tentative consequence: repayable to its extremely laconic half-life in fauna tissues, ODC is speedily induced or suppressed by agents which check development.

The plan for the Experiment to show the Hypothesis: Lactating CD female rats with litters of 10 pups were housed in breeding cages in a vivarium keep at 22 degrees Celsius with a 12-h light-dark cycle, and provided food and urine ad libitum. Animals were killed by decapitation and lungs and livers were quickly dissected, homogenized in 19 volumes of ice-cold 10mM Tris-HCl, centrifuged at 26,000 x g for 20 min, and the supported assayed for ODC activity by a modification of the system of Russell and Synder. good liver ribonucleic acid was extracted with acid guanidinium thiocyanate-phenol-choloform according to Chomczynsky and Sacchi. The determination relate to the Objectives: The results from these studies demonstrate that neonatal lung ODC activity is highly sensitive...
