The estrogen receptor (ER) is present in a wide variety of mammalian tissues and is required for the physiological responses of estrogen, including estrogen-induced tissue-specific changes in gene expression. But most of our knowledge on the regulation of ER mRNA levels comes from in vivo steroid replacement experiments or cancer cell lines that express the ER. Thus the present study was attempted to determine 1) the anterior pituitary ER mRNA levels during rat estrous cycle 2) if estradiol itself directly modulates the ER mRNA levels in cultured rat anterior pituitary using RT-PCR method. In rats with 4 day estrous cycle, the ER mRNA levels in anterior pituitary gland reached to maximum at proestrus 11:00h just before serum estradiol concentration showed the highest. From then, the ER mRNA levels gradually declined during the rest of the proestrus. On the other hands, in cultured rat anterior pituitary cells, the ER mRNA levels were significantly decreased by the treatment of estradiol. These results indicate that the surge of estradiol was proceeded by the increase in pituitary ER mRNA levels during the proestrus and in cultured anterior pituitary cells, estrogen might be involved in the down-regulation of the ER mRNA levels.

To observe the role of oxygen free radical and enzymatic scavengers in cerebral ischemia, an infarction model was made using transorbital occlusion of the middle cerebral artery in cats. The changes of the superoxide radical production and the activities of superoxide dismutase and catalase were measured. The results were as follows ; 1) The infarction of the left middle cerebral artery(MCA) territory was identified with intracardiac perfusion of a TTC solution after transorbital occlusion. 2) The superoxide radical activities after occlusion of the left MCA were not changed in all groups except for the decrease in 6 hours group of the right side compared to the control group(p<0.05). 3) The Mn-superoxide dismutase activities of the left side in the 12 hours group were significantly higher than those of the right side(p<0.01) and those in the control group(p<0.05). 4) The Cu, Zn-superoxide dismutase activities of the left side in the 3 hours group after occlusion of the left MCA were significantly higher than those in the control group(p<0.05). 5) The catalase activities of the left side in the 3 hours, 6 hours and 12 hours groups after occlusion of the left MCA were significantly higher than those of the right side(p<0.05). 6) The catalase activities of the left side in the 12 hours group after occlusion of the left MCA were significantly higher than those in the control group(p<0.05). The authors suggest that the enzymatic scavangers such as Mn-SOD, Cu, Zn-SOD and catalase increased in the infarcted brain, which means an involvement of free radicals in cerebral infarction.

OBJECTIVES: Our purpose was to determine the efficacy of maternal corticosteroid therapy in the prevention of neonatal respiratory distress syndrome. STUDY DESIGN: The data in this study was taken from 136 women who participated in prematurity prevention programs at two hospital. Of 136 women who were delivered at 25 to 34 weeks, 68 received dexamethasone and 68 did not. 'I'he frequency and relative risk of adverse outcomes, including repiratory distress syndrome, necrotizing enterocolitis, neonatal sepsis and maternal infection wcre compared by means of univariate techniques. RESULT: When dexamethansone was administered, there was a lower incidence of respiratory distress syndrome at between 30 to 32 weeks gestation (relative risk of treatment group vs control group=0.425, p<0.05) and there was no statistical difference between 24 to 26 weeks (relative risk of treatment group vs control group=0.833, p>0.05). I'here was no statistical difference between 33 weeks to 34 weeks (relative risk of treatment group vs control group=0.782, p>0.05). 'I'here was no statistical significance in the incidence of maternal infection, neonatal sepsis or necrotizing enterocolitis (p=0.808, p=0.698, p=0.559). CONCLUSION: Dexamethasone appears to significantly reduce neonatal respiratory distress syndrome at between 30 and 32 weeks gestation.
