Microsomal fractions isolated from rats treated with halothane and from control animals were assayed for their capacity to dechlorinate methoxyflurane. Microsomes from halothane-treated rats demonstrated about 2.6 times the capacity to dechlorinate methoxyflurane as microsomes from control animals. Electron microscopy showed that liver cells from halothane-treated animals, when compared with hepatocytes from control rats, had increased amounts of smooth endoplasmic reticulum, an increased number of lipid droplets, and more microbodies per cell. Rough endoplasmic reticulum and glycogen were decreased by halothane treatment. We interpret these results to mean that halothane induces the rough endoplasmic reticulum to synthesize enzymes required for the biotransformation of methoxyflurane. It is suggested that these enzymes are placed in membranes of the rough endoplasmic reticulum. This organelle is converted to smooth endoplasmic reticulum and here the biotransforming enzymes function to dechlorinate methoxyflurane.","PeriodicalId":101557,"journal":{"name":"The American journal of anatomy","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1972-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128233291","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 released secretory products were found in the form of discrete granules, with or without a perigranular membrane, in intercellular spaces, between the plasma membrane and the parenchymal basement membrane, in the perivascular space, in the endothelial cytoplasm, and in the lumen of capillaries. Vesicles containing material which resembled that in the perivascular space were observed in endothelial cells. \u0000 \u0000 \u0000 \u0000Interpretation of these observations has led to the proposal of the theory that secretory products of the adenohypophysis may be liberated from parenchymal cells in the following way: by fusion of the perigranular membrane with the plasma membrane (merocrine) or by the detachment of small processes containing secretory granules (“microapocrine”). It is further believed that the discharged products may be transported into circulation in three different manners: by diffusion of dissolved material through the fenestrated endothelium, by active transport of dissolved secretory products by the endothelial cells, or by active transport of intact secretory granules through the endothelial cytoplasm.","PeriodicalId":101557,"journal":{"name":"The American journal of anatomy","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129562354","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}
