N/A To clarify the mechanism of ethanol induced gastric mucosal damage and protective effect of d-methyl prostaglandin (PG) E against the gastric mucosal damage, the activiteis of superoxide (SOD), catalase, glutathione peroxidase of rat stomach were measured after topical application of ethanol in stomach of rats with or woitout d-methyl PGE pretreatment.Variable doses of d-methy1 PGE were given intragastrically at 30mins before the administration of 75% ethanol.The results were summarized as follows;1) The SOD, catalase, glutathion peroxedase activities increase with different concentration of ethanol.2) The each eazyme actinity also shwed dose dependent decrease in the d-methyl PGE pretreatment group than only 75% ethanol application group. According to our experimint it was suggested that superoxide radical may play a role on ehtnol-indeced gastric damage in rats.

To accomplish the pupose of this study, l have compared two groups : Superior group of 30 players and less-superior proup of 30 platers to examone the effect of competition anxiety for western style acheries tournament records and training records. The superior group contains the players who have won the prize for national tournament and less-superior group does not but same record in training stage. The differences of tournament records, training records and SCAT score between these two groups have been verified by using t-verification. In addition, pearson's correlationship of these two groups and SCAT score. The results of this study has shown : Frist, SCAT score shows statistical differences between two groups (P〈001) Second. No statistical differences in single and frand training records, but in tournament records(P〈001) Third, the meaninful differences of SCAT score has shown between male and female superior group and less-superior group Fourth, No difference of training records of single and grand but in tournament records of these two groups. Fifth, the SCAT score, has a reliable relation between two groups. Finally, the SCAT score, single and grand training records shows no difference statistically but in tournament records has high correlation between these superior group and less-superior group. According to this study, the competition anxiety has a negative effect for Western-Style acheries in tournament records. The level of this negative effect is greater among less-superior players compared to superior group.
