Ultrastructural observations following lipid extraction and histochemical data showed that lipid components are not present in the secretory granules. In fact, while histochemical reactions are completely negative, secretory granules from lipid-depleted glands retain all their morphological characters. These results led us to emphasize that, at least in human seromucous cells, lipids are not directly involved in the salivary secretion. This conclusion, which is supported by the biochemical data concerning the lipid content in human saliva, disagrees with the findings obtained in rat and guinea pig salivary glands. However, this discrepancy may be ascribed to the specific biochemical and ultrastructural differences found in the salivary glands of the various mammalian species.</p>","PeriodicalId":76491,"journal":{"name":"Rivista di istochimica, normale e patologica","volume":"20 4","pages":"159-66"},"PeriodicalIF":0.0,"publicationDate":"1976-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12204838","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 denaturation and renaturation treatments which should act specifically on the screws of the DNA and therefore should not affect the Feulgen reaction, act in a specific manner, probably going away another histonic components. On the dehistonized material the action of the hydrolysis of the Feulgen reaction would add up to that implicit in the dehistonization treatment and would cause a rapid fall of the values for loss of material as consequence of depolymerization facts, according to Andersson and Kjellstrand (1975). The successive renaturation treatment both on dehistonized and on non dehistonized material does not change significantly the values precedently obtained and this confirms the idea that the rilevability of the Feulgen reaction is not influenced by the treatments \"per se\" but by the deep \"touching\" of the chromatin components.</p>","PeriodicalId":76491,"journal":{"name":"Rivista di istochimica, normale e patologica","volume":"20 4","pages":"177-82"},"PeriodicalIF":0.0,"publicationDate":"1976-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12204839","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}
