Using high performance liquid chromatography, the particle size of the lipoprotein was determined with elution volume, which was precisely correlated with the particle size. The particle size of low density lipoprotein (LDL) from the diabetics with normolipidemia is larger than that from the nondiabetics (p less than 0.001) in the elution pattern of triglyceride. The examination of the elution pattern of the triglyceride and cholesterol revealed that this large LDL was composed of a large amount of triglyceride. These characteristics of the large LDL resembled that of the atherogenic intermediate density lipoprotein. The particle size of high density lipoprotein (HDL) from the diabetics with normolipidemia was larger than that from the nondiabetic controls (p less than 0.001), detected by the elution pattern of triglyceride. The comparison of the triglyceride and cholesterol elution pattern indicated that also the large HDL in the diabetics with normolipidemia was rich with triglyceride, which was reported to inhibit the activity of the lipid transfer protein. These facts revealed that the disorder of the lipid metabolism not accompanied with hyperlipidemia produced the large LDL and HDL, which might lead to the excess mortality rate of the ischemic heart disease in the diabetics even with normolipidemia.","PeriodicalId":22311,"journal":{"name":"The Bulletin of Tokyo Medical and Dental University","volume":"38 4","pages":"63-71"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12927501","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":"New restoration and direct pulp capping systems using adhesive composite resin.","authors":"T Kashiwada, M Takagi","doi":"","DOIUrl":"","url":null,"abstract":"There have been many arguments on the irritating mechanisms of the composite resin on the dental pulp. While the direct irritative effect of the resin has been preferred, some authors considered that the marginal microleakage and the resulting bacterial infection play a more important role in inducing the complicating pulp irritation. We developed a new filling technique, called the direct inlay restoration method, which could prevent the marginal leakage associated with the polymerization shrinkage of the adhesive composite resin. In this study, we tried to apply our method clinically. None of the 440 cases which were filled with the adhesive composite resin and 60 cases out of 64 cases in which the pulps were directly capped with the adhesive composite resin developed any signs and symptoms of pulp irritation. The other 4 cases developed signs of pulp irritation. Two of those 4 cases were pulpectomized due to spontaneous pain and the other 2 cases turned out to be well after re-restoration. With the informed consent of the patients, the direct pulp capping using the adhesive composite resin was experimentally performed on 6 caries-free 3rd molars and the histopathological examination of these capped molars revealed that neither significant degenerative nor inflammatory changes were brought about in the dental pulp. These clinical and histopathological observation suggest that the dental pulp irritation after resin filling is not induced by the composite resin itself.","PeriodicalId":22311,"journal":{"name":"The Bulletin of Tokyo Medical and Dental University","volume":"38 4","pages":"45-52"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12928335","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":"Study on cholesteryl ester transfer activity in coronary heart disease.","authors":"Y Fujinuma, A Tanaka, H Maezawa","doi":"","DOIUrl":"","url":null,"abstract":"The net cholesterol transfer activity from high density lipoprotein (HDL) to low density lipoprotein (LDL) was determined in the patients with coronary heart disease (CHD) to examine its effect on the pathogenesis of arteriosclerosis. Furthermore, in the CHD patients with high HDL cholesterolemia (more than 60 mg/dl), the HDL particle size was measured by high performance liquid chromatography. A significant cholesteryl ester transfer activity (P less than 0.02) was noted in the CHD patients with low HDL cholesterolemia (less than 60 mg/dl). The rate of cholesteryl ester transfer activity (cholesteryl ester transfer activity/hour) inversely correlated with the serum HDL cholesterol value (r = -0.483, P = 0.096) in the patients with CHD. These results suggest that an increase of CETA caused a low HDL cholesterol value in the CHD patients with low HDL cholesterolemia and it may have the risk of causing CHD. However, an increase of the CETA was not found in the CHD patients with high HDL cholesterolemia compared to the normal subjects, the HDL particle size being significantly greater than that in the normal subjects. In the CHD patients with high HDL cholesterolemia, the large size of HDL may have the risk of causing CHD.","PeriodicalId":22311,"journal":{"name":"The Bulletin of Tokyo Medical and Dental University","volume":"38 3","pages":"27-33"},"PeriodicalIF":0.0,"publicationDate":"1991-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13093269","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}
