Experimental study in the rat.","authors":"S Valérdiz,&nbsp;J J Vázquez","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Cyanamide is a drug frequently used as aversion therapy in chronic alcoholism. A chronic hepatocytic lesion induced by cyanamide has been described by a member of our team over the last few years. It consists of distinctive cytoplasmic inclusion bodies, similar to those observed in Lafora's disease. The inclusion body-bearing liver cells resemble the ground-glass hepatocytes observed in type B viral infections. This hepatocytic lesion is predictable and reproducible in the rat liver. The high frequency of alcoholic patients with inclusion bodies observed in Spain is striking in contrast with the scarcity of cases published abroad. The medicine commonly used in Spain contains plain cyanamide, while Temposil used in Canada and Dipsan used in Scandinavia contain its calcium form (calcium carbimide). In an attempt to discover if the chemical nature of the drug is an important determinant in the development of the lesion, the present study was carried out using groups of Wistar rats. One group received cyanamide and the other one calcium carbimide. The drug was placed in the stomach via a cannula, daily, at a dose of 16 mg/kg body weight, for 25 weeks. The characteristic inclusion bodies were only found in the group receiving plain cyanamide.</p>","PeriodicalId":77670,"journal":{"name":"Applied pathology","volume":"7 6","pages":"344-9"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13783922","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 this study we have analyzed the relationship between these four parameters in 78 ductal infiltrating carcinomas of the breast. No relationship was found between PF and the presence of lymph node metastatic disease: however, in the tumors with positive nodes, a limited metastatic diffusion (1-3 lymph nodes) was significantly associated with PF (p less than 0.05). Our study failed to demonstrate any relation between estrogen receptor (ER) and both presence and extension of nodal involvement; in contrast, the tumors with limited metastatic diffusion (1-3 lymph nodes) had a significantly higher prevalence of PR positivity (p less than 0.05). Furthermore, PF was strongly associated with PR (p less than 0.001) and less well with ER (p less than 0.05). The simultaneous presence of PR and marked PF was strongly correlated with limited metastatic involvement of the axilla (p less than 0.007). Tumor size was correlated with the number of positive nodes (p less than 0.001), but not with PR or PF. The results demonstrate that PR status, PF and tumor size are related to limited metastatic diffusion of the axilla: furthermore PF and PR have been shown to be strongly related and we have demonstrated that, at least in ductal infiltrating carcinoma, the simultaneous presence of them identifies a subset of tumors with low metastatic capacity independently of tumor size.</p>","PeriodicalId":77670,"journal":{"name":"Applied pathology","volume":"7 4","pages":"225-32"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13696090","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}
