These differentiated striated muscle fibers consist of multinucleated cells resembling skeletal muscle fibers. They appear mainly in the pars distalis, though occasionally in the pars intermedia of the grafts. Although most glandular cells disappeared due to necrosis in the center of the grafted anterior pituitary, where the striated muscle fibers occurred, the folliculo-stellate cells were well preserved in this region and formed elongated myotube-like structures. The muscle fibers appearing in the central pars distalis were in close contact to the folliculo-stellate cells and also to the marginal epithelium of the pituitary cleft. In these cases the striated muscle fibers and folliculo-stellate cells were surrounded by a common basal lamina. This close association between heterotopically differentiated muscle fibers and the normally occurring folliculo-stellate cells strongly suggests a close relationship in differentiation and function between these different cells.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 5","pages":"567-78"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.567","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14564079","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}

After 6 months of age, vacuoles appeared first singly and later became clustered in the seminiferous epithelium. With the appearance of the vacuoles, the epithelium started to release spermatids and spermatocytes into the lumen. Multinucleated giant cells occasionally appeared in the epithelium and were also released to the lumen. The epithelium, when markedly depleted of germ cells, was composed mainly of Sertoli cells. The lumen of the atrophied tubules occasionally contained accumulations of macrophages, sperm aggregations, and nodules of a homogeneous material covered with flattened epithelial cells. The basement membrane surrounding the atrophied tubules thickened corresponding to the degree of atrophy. The atrophied tubules initially appeared in patches and then spread throughout the testis. Leydig cells increased in amounts with age. The increase of Leydig cells was distinct around severely atrophied tubules with a thickened basement membrane. These changes are discussed in comparison with autoimmunized testes which show similar histologic changes.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 5","pages":"533-44"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.533","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14564078","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}

This technique was employed to demonstrate the three-dimensional organization of the reticular fibers of the human pancreas. The cellular elements were effectively removed by treatment of the tissue pieces with a 10% aqueous solution of NaOH for 3-4 days at room temperature. Thin layers of the reticular fibers surrounding the acini and ducts formed a three-dimensional interstitial compartment. The reticular fiber sheaths for the blood vessels coursed through the compartment. In the lobule, there were scattered round or oval capsules for the islets of Langerhans. The capsule also consisted of reticular fibers. Within the capsule, reticular fiber sheaths for accommodating islet capillaries, representing the pericapillary spaces, formed a three-dimensionally anastomosing network. The channels for the capillaries ensheathed by the reticular fibers in the islet were continuous with those in the surrounding exocrine pancreas; thus, the insulo-acinar portal system was confirmed to exist in the human pancreas. This study also maintains that the present method is useful for examining the microvascular organization of the islet.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 5","pages":"557-66"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.557","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14455562","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}

In mature (8-10 weeks old) rat ovaries, the theca interna cells of secondary as well as Graafian follicles, and the interstitial gland cells were all strongly stained with anti-17 beta-HSD antibody. However, granulosa cells, corpus luteum cells, oocytes and peritoneal epithelial cells were negative against this staining. In the ovaries of 1-week-old rats, all these cells were negative to immunostaining for 17 beta-HSD. In the ovaries of 2-week-old rats, the theca interna cells of secondary follicles and the interstitial gland cells showed a positive reaction for the 17 beta-HSD activity. Electron microscopic examination demonstrated the presence of characteristic structures for steroid secretory cells such as many lipid droplets, well developed smooth endoplasmic reticulum, and oval mitochondria with tubular cristae in the theca interna cell of secondary as well as Graafian follicles and in the interstitial gland cell of mature rat ovaries. In the ovaries of 1-week-old rats, all the theca cells of the primary and secondary follicles were fibroblast-like in their shape and fine structure, and typical interstitial cells were not recognized. In the 2-week-old rats, some of the theca interna cells and interstitial cells were well differentiated in ultrastructure, showing characteristic features for steroid secretory cells. These findings indicate that by 2 weeks after birth, theca interna cells and interstitial gland cells acquire the ability for testosterone production as seen in mature rat ovaries.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 5","pages":"545-56"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.545","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14605999","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 endothelium and media of lymphatic capillaries are characterized by a strong 5'-nucleotidase activity, whereas blood capillaries reveal no or significantly lower activity. Alkaline phosphatase activity, on the other hand, missing in the lymphatic capillaries is positive in most of the blood capillaries. For the histochemical visualization of the entire blood capillary bed, dipeptidyl peptidase IV-activity has to be used together with alkaline phosphatase. Various fixation and detection methods of 5'-nucleotidase are compared. In order to demonstrate 5'-nucleotidase activity, a method modified after Heusermann (1979) is considered to be most suitable. The results obtained are discussed with regard to their significance concerning the visualization of lymphatic capillaries. They are compared with a series of investigations in which alkaline phosphatase and dipeptidyl peptidase IV-activity are visualized in blood capillaries additional to the 5'-nucleotidase reaction. Various color reactions reveal a differentiation between blood capillaries and small lymphatics. The isolated visualization of 5'-nucleotidase activity with a simultaneous inhibition of alkaline phosphatase with L-tetramisole is considered to be the best way to histochemically demonstrate lymphatic capillaries. It was shown for the first time that only in the presence of L-tetramisole can small lymphatics be adequately visualized. A satisfactory differentiation between blood and lymphatic capillaries succeeded by means of a different color intensity of the reaction product.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 5","pages":"505-14"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.505","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13969586","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}

No staining with the antibody was detected in the developing tunica media of the great arteries in the distal truncus at this stage. During septation, on the 5th day of incubation, intense staining with the antidesmin antibody was observed in the cell condensation of the AP septum. In the 6-day-old embryo, the staining in the AP septum was reduced, but fluorescence by staining with the antibody was observed in the developing tunica media. No fluorescence was detected in other mesenchymal cells in the truncal swellings. Because of the time of appearance and the localization of antidesmin reactivity in the developing AP septum, it is suggested that muscle-type cells exist in the AP septum, and that these cells may perform an important function in septation.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 5","pages":"525-31"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.525","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14455561","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}
