Seven weeks old male Wistar rats were hindlimb-unloaded by tail suspension for 9 consecutive weeks. Motor tests were performed immediately after the termination of suspension and recovery patterns were checked during 8 weeks of ambulation recovery. Although all of the control rats were able to land smoothly by using the four limbs as the shock absorber, the unloaded rats landed by hitting their abdomen. The hindlimb-unloaded, but not control, rats dorsi-flexed their trunk during fall. The mean angle of abdominal side was approximately 145 degrees in control and approximately 215 degrees in unloaded rats. Even though such phenomena were maintained for approximately 12 hours, the response of the trunk angle recovered significantly 2 days later. However, it was not normalized completely even after 8 weeks. Hyper-extension of ankle joints and eversion of hindlimbs at landing were also noted in the unloaded rats. These phenomena were not recovered at all. It was generally suggested that severe detrimental effects on the landing performance of rats are induced following 9-weeks of suspension. And some of the responses are irreversible.</p>","PeriodicalId":83384,"journal":{"name":"Uchu koku kankyo igaku","volume":"39 2","pages":"21-9"},"PeriodicalIF":0.0,"publicationDate":"2002-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22479742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this project was to investigate personal changes during 110-day isolation in the Russian Experiment Module. The Giessen Test (GT) was used to determine if personal traits of the subjects change during isolation. The GT was chosen as an individual diagnostic instrument because it includes an important range of social views and reactions. The GT reveals which characteristics a person, in this case a crew member, ascribes about him/herself (personal-picture). Questions about personal qualities were asked indirectly to better reveal psychosocial tendencies and defense mechanisms. Many personality tests focus on deriving information about how the subject \"really\" is. However, the GT deviates from this pure individual psychological ideal test construction and focuses on how the subject represents him/herself in psychoanalytically relevant categories in group relationships. We hypothesized that personal traits become more explicit and accentuated during prolonged confinement. Accentuations of personal traits were predicted due to the experience on MIR station where the American astronauts realized how different their Russian colleagues become compared to their common training time on the ground. The formation of subgroups was predicted, as it is often observed within different types of groups in Japanese, Russian isolation studies and at the Japanese Antarctic research station, Syowa.</p>","PeriodicalId":83384,"journal":{"name":"Uchu koku kankyo igaku","volume":"39 2","pages":"57-60"},"PeriodicalIF":0.0,"publicationDate":"2002-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22479748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
