Application of post-implantation embryo culture to problems in teratology. 胚胎着床后培养在畸形学问题中的应用。

Embryos explanted at 9 1/2 days (head-fold stage) and incubated for 48 h at 40.5 degrees C were retarded and abnormal and these effects were more severe in embryos cultured at 41 degrees C. Embryos exposed to 40 degrees over this period were superficially normal, but separate head and body protein determinations and careful measurement of the head dimensions showed them to be microcephalic. Addition of 12-15 mg/ml D-glucose to the culture medium of embryos grown in vitro over the same period also produces malformations. This teratogenic action of D-glucose is distinct from but exacerbated by its osmotic effect. Embryos explanted 12 h earlier (i.e. at 9 days of gestation) and cultured for 66 h were more sensitive to excess glucose--abnormalities were produced by 6-9 mg/ml exogenous D-glucose. Embryos explanted at 11 1/2 days of gestation and cultured for 18 h responded to both 10% CO and suboptimal oxygen levels with a reduction in growth rate and an increase in the ratio of lactate produced to glucose consumed, suggesting a shift to less efficient anaerobic energy metabolism.</p>","PeriodicalId":72058,"journal":{"name":"Acta morphologica Academiae Scientiarum Hungaricae","volume":"28 1-2","pages":"117-24"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18456907","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 amphicrine (endo-exocrine) cells in the human gut, with a short reference to amphicrine neoplasias. 人类肠道内的两性(内外分泌)细胞，简要介绍两性肿瘤。

Depending on their behaviour under silver impregnation, they are divided into three subgroups: the mucoargentaffine, the mucoargyrophilic and the mucoargyrophobic cells. They were detected electron microscopically in 1969, but they were histologically verified and identified as mucus-excreting endocrine elements only in 1977. Since 1969 such cells have also been observed in normal and regenerating rat and mouse stomachs. Our own human material includes stomach (3 cases), appendix (12 cases), colon (1) and a series of amphicrine proliferations and tumours. Two cases of chronic gastritis and one chronic peptic ulcer with metaplastic and regenerating epithelium contained mucoargyrophilic cells with mucus below the nucleus in the atypical glands. The possibility of endocrine granules being sluiced out in the mucous grains is discussed. Of the appendices only two were normal (ages 6 and 7 years), 10 showed pathological changes: there were seven neurogenic appendicopathies (14-58 years), one lymphatic hyperplasia, and one hyperplasia of mucoargyrophobic cells with mucostasis. Mucoargentaffine cells far outnumbered the mucoargyrophilic and mucoargyrophobic cells. The mucus may have either an apical or basal location; in the latter case, paracrine secretion into the subepithelial lamina propria was seen. As neoplastic cells, the amphicrine cells form the rare amphicrine tumours (goblet-cell and muco-adenoid carcinoids) of the appendix and colon. They are also found in mucinous cystadenomas of the ovary [26], in the enteral type of a nasal carcinoma [27,28], and in a 5-HT-carcinoid of the ovary [15]. They are therefore to be regarded as a differentiation disorder of the endocrine cells under the pathological conditions of appendicopathy, hyperplasia, metaplasia and true neoplasias.</p>","PeriodicalId":72058,"journal":{"name":"Acta morphologica Academiae Scientiarum Hungaricae","volume":"28 1-2","pages":"37-58"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18456913","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}
