It may be said that the less negative effect is induced by 2.5% ethanol and by the association: \"glucose + 2.5% ethanol\", that the damage induced by only glucose seems to improve in presence of 2.5% ethanol, that in presence of phospholipids the cells appear all full of big lipid drops (especially in the condition: \"phospholipid + ethanol\") and that 5% ethanol deeply appears to impair and alter the cultures, as it was been observed in our previous experiences.</p>","PeriodicalId":8818,"journal":{"name":"Biochemistry and experimental biology","volume":"16 2","pages":"107-9"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18359903","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}
