Additionally, the findings of three dogs with an increased activation of the interstitial gland cells after 12 Gy whole-body X-irradiation were also presented. Three groups of interstitial gland cells were distinguished: the immature, the mature and the degenerating cells. The steroid-specific cell organelles of mature interstitial cells were highly developed after irradiation-induced stimulation. At the onset of generation, a circular arrangement of dilated endoplasmic vesicles (demarcation channel) characterized the cells of non-irradiated and of irradiated ovaries. During the early stage of degeneration, different degrees of nuclear shrinkage and of vacuolation of the cytoplasm were seen. A lace-like vacuolation was common in the irradiated ovaries. During the advanced stage of degeneration, the cysts ruptured with resultant shedding of the cytoplasmic organelles into the intercellular space. A new cellular membrane was simultaneously reconstituted and a fibrocyte-like cell appeared. The process is referred as \"secretory degeneration\" and is presented as a hypothesis.</p>","PeriodicalId":75532,"journal":{"name":"Archives d'anatomie microscopique et de morphologie experimentale","volume":"74 2","pages":"167-77"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15202492","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}

{"title":"Ultrastructure of venom glands in the frog (Rana esculenta).","authors":"G De Perez,&nbsp;C Hindelang","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Electron microscopic study of skin venom glands in the frog, Rana esculenta, revealed the syncytial structure of the inner (secretory) wall which presents two distinct zones: a basal (juxtamuscular) one, which contains nuclei and major cytoplasmic organelles, and an apical one where large electron-dense granules form and accumulate. Granules are seen to arise inside clusters of tightly packed smooth endoplasmic reticulum (SER) elements, which suggests that the SER system is mainly involved in synthesis of this material. A high glutaraldehyde concentration (5%) also reveals a poorly defined material filling the intergranular cytoplasm. No apical limits to the syncytium could be traced, which suggests massive holocrine secretion. Nerves insinuate between the muscle cells and occur all along the internal face of the muscular layer, sometimes in close contact with the syncytium. The gland duct, the wall of which consists of epidermal cells, is blocked, in contact with the gland, by an epidermal bud linked externally to the muscle layer surrounding the gland. Thus, only strong muscle tension such as to expel all or part of the epidermal bud can trigger granule release. This phenomenon can be induced by the subcutaneous injection of epinephrine, but the high and distressing dose needed to provoke appreciable changes in venom glands renders unlikely any natural intense venom release triggered by epinephrine in the frog.</p>","PeriodicalId":75532,"journal":{"name":"Archives d'anatomie microscopique et de morphologie experimentale","volume":"74 3","pages":"216-27"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14996918","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}
