Immunoperoxidase labeling studies found that in control tissues binding by Soybean Agglutinin (SBA), Dolichos Biflorus Agglutinin (DBA), Wheatgerm Agglutinin (WGA), and Ricinus Communis Agglutinin-120 (RCA-120) was consistently higher than that of Peanut Agglutinin (PNA), Ulex Europaeus Agglutinin-1 (UEA-1), Concanavalin A (ConA) and Helix Pomatia Agglutinin (HPA). Tissues from ulcerative colitis and Crohn's disease patients, showed increases in DBA and SBA binding, a reduction in HPA binding, and changes in the distribution of PNA, UEA-1, RCA-120, and HPA labeling sites. These results demonstrated that the expression of lectin-binding sites on human intestinal goblet mucin was specifically altered in ulcerative colitis and Crohn's disease, thus possibly providing another approach to the assessment of neoplastic risk on these diseases.</p>","PeriodicalId":73745,"journal":{"name":"Journal of Experimental Pathology","volume":"4 2","pages":"69-78"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13909112","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}

Proceeding to a more detailed survey we were able to observe various types of retrovirions. All of them were present in the different activated cell lines. They were: intracisternal R-type particles (IRP), intracisternal A-type particles (IAP), intracytoplasmic A-type particle (ICAP), intramitochondrial A-type particle (IMAP) and M-432 virus-like particles.

We have found that the oxidation of [1-14C] octanoic acid in homogenates of leukocytes from one of the Reye syndrome patients was only 38 percent of the control, whereas oxidation of [1-14C] palmitic and [1-14C] lignoceric acid was slightly increased. The level of lipid peroxides in the serum of both of the Reye Syndrome patients was 4.42 and 3.04 times higher than the control level. These results suggest that impaired oxidation of medium chain fatty acids (octanoic acid) and higher levels of lipid peroxides may contribute to the pathogenesis of cellular toxicity in Reye Syndrome. Reye Syndrome (RS) was first described by Reye et. al. in 1963 and is now recognized as an important cause of morbidity and mortality in infants and children. The clinical course in RS consists of an antecedent viral illness with subsequent encephalopathy and hepatic dysfunction. Laboratory findings in RS include hypoglycemia, hyperammonemia, free fatty acidemia, elevated organic acids and amino aciduria. The ultrastructural findings in RS patients include changes in mitochondria, smooth endoplasmic reticulum morphology, and an increase in the number of peroxisomes. The elevation of serum free fatty acids in RS and their decrease in patients who improve clinically suggests a disturbance in fatty acid metabolism. To understand the role of free fatty acids in the pathogenesis of RS, we examined the levels of lipid peroxides in plasma and catabolism of fatty acids of different chain lengths in leukocytes from RS patients.</p>","PeriodicalId":73745,"journal":{"name":"Journal of Experimental Pathology","volume":"4 3","pages":"133-9"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13909120","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}
