There was no measurable effect on the function of existing osteoblasts or osteoclasts during this short term (5 day) experiment. Also, incorporation of plutonium into osteoclasts did not disrupt the ability of parathyroid hormone to maintain normal calcium levels. However, it could be demonstrated that plutonium, for the first 48 hours after administration, affected certain of the undifferentiated bone cells, which in turn prevented the increased osteoclast production normally seen following endogenous parathyroid stimulation.","PeriodicalId":20675,"journal":{"name":"Proceedings of the Society for Experimental Biology and Medicine","volume":" ","pages":"77-81"},"PeriodicalIF":0.0,"publicationDate":"1965-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3181/00379727-119-30103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40799771","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 rapidity and magnitude of fat accumulation was greatest in rats fed the 38% lard diet and least in those receiving the one containing 5% lard. In previous studies the same diets were fed for 15 weeks: the 38% lard diet produced the greatest incidence and the most severe degree of cirrhosis, whereas the group fed the 5% lard diet had the least severe degree of liver damage.
