The latter had to be administered at least 2 hr before carrageenin challenge to achieve such inhibition. Moreover, inhibition was blocked by the simultaneous injection of actinomycin D. Polyamines also inhibited local bluing reactions to histamine in rats and similarly had to be administered 3 hr previously to achieve inhibition. Polyamines were shown to be glucocorticoid-type anti-inflammatory drugs, and may be glucocorticoids mediators of the synthesis of the postulated vascular permeability inhibitory protein that do not inhibit phospholipase A2 activity. Neutrophil chemotaxis was inhibited by polyamines in a concentration-dependent manner. In contrast to the experience with carrageenin paw edema, simultaneous addition to actinomycin D did not block the inhibitory action of polyamines on neutrophil chemotaxis. These results suggest that polyamines possess at least 2 different anti-inflammatory mechanisms. The first is mediated by the synthesis of an anti-inflammatory protein, and the second consist of direct action on leukocytes.","PeriodicalId":12643,"journal":{"name":"Gifu Shika Gakkai zasshi = The Journal of Gifu Dental Society","volume":"17 2","pages":"509-15"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13288187","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}

Two hundred twenty rats were divided into three groups: a control group, a group of subjects which resection of the left facial nerve, and a sham operation group. The rats were killed 1, 5, 10, 30, 60, 90, 120 days later. The superficial and deep masseter muscle fibers on both sides were classified into type I and type IIA or IIB on the basis of myosin ATPase activity and the diameter of these fibers was measured. The masseter muscles were stained with H&E and NADH-TR. Electromyogram recordings were analyzed during the rest position, stretch reflex, voluntary action and eating of solid foods in half of all groups. (1) The face of rats after denervation deviated to the right side, and the maxillo-facial skeleton was affected from the 30th day. (2) In the denervation groups the right side showed higher action potentials than the left side. (3) In the deep masseter muscles near muscle spindle in the denervated groups, the percentage of type I fibers on the right side increased on the 90th day, and that of type IIA fibers decreased on the 30th day. (4) The diameter of the deep masseter muscle fibers, of type I, IIA and IIB increased on the right side. These results prove that facial nerve denervation led to a functional disorder and a transformation of growing direction.","PeriodicalId":12643,"journal":{"name":"Gifu Shika Gakkai zasshi = The Journal of Gifu Dental Society","volume":"17 1","pages":"203-22"},"PeriodicalIF":0.0,"publicationDate":"1990-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13289261","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, the adaptation of HAp and alpha-TCP as a pulpotomy agent was studied histopathologically. In this study, HAp granules with a sintering temperature of 1,200 degrees C and sieved through a 37 micron sieve, and APATITE LINER TYPE I (Sankin CO.) as alpha-TCP were used. Calcium hydroxide served as a control. The physical properties of these experimental materials were evaluated and the reaction of pulp tissue to the materials was examined histolongically in dogs. alpha-TCP mixed with saline solution showed more homogeneous and higher viscosity than HAp mixed with saline solution. When alpha-TCP was applied on the site of exposure of a pulp following pulpotomy, the mechanically harmed pulp tissue was healed earlier than when HAp was applied. A hard tissue was formed earliest when calcium hydroxide was used, and then in the order of alpha-TCP and HAp. When HAp was applied, osteodentin was formed and when alpha-TCP was applied, dentin was formed on the site of exposure of a pulp following pulpotomy. When HAp or alpha-TCP was applied, the calcification in the initial stage was not observed. The calcification in initial stage was observed when calcium hydroxide was applied. These results suggest that alpha-TCP is useful as a pulpotomy agent.","PeriodicalId":12643,"journal":{"name":"Gifu Shika Gakkai zasshi = The Journal of Gifu Dental Society","volume":"17 1","pages":"223-45"},"PeriodicalIF":0.0,"publicationDate":"1990-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13289262","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}

Fixed bridges were twice more frequently used for anterior teeth during this period than during the previous period. For a single missing tooth, fixed bridges amounted to 90% and removable partial dentures to 10%, as they did in the previous period. For two or more missing teeth, the use of fixed bridges was some what increased compared to the previous period. As in the previous report, the use of so-called one-tooth denture was most frequent for missing lower first molar.

For removable partial dentures, the average number of missing teeth and that of abutment teeth were 6.1 and 2.8 respectively. Removable partial dentures for two missing teeth with two abutment teeth were most frequently used. Full cast crowns were most frequently used for bridge retainers, followed by facing crowns.

{"title":"[Studies on application of pure titanium for cast plate].","authors":"M Sakai","doi":"","DOIUrl":"","url":null,"abstract":"Pure titanium produced by a commercial pure titanium casting system was studied for use as a cast plate for clinical application. The mechanical properties, elemental analysis, castability, adaptability of pure titanium and adhesion to denture base resin were investigated. The interfacial zone of the pure titanium castings was composed of a layered structure obtained by reaction with phosphate bonded Al2O3/SiO2 investment material. Vicher's hardness at 100 microns thick from the surface was higher than that in the inner part by oxidation. Cast pure titanium showed tensile strength, elongation and hardness close to those of the type III or IV dental gold alloy. The castability of pure titanium was lower than that of Co-Cr alloy and pure titanium castings also had large casting defects. Adaptability between pure titanium cast plate and the working model was satisfactory when reversible hydrocolloid impression material was used with heating-bath treatment in the refractory model. The tensile and compressive shear bonding strength of pure titanium to heat-curing or self-curing resin were similar to that of the Co-Cr alloy, and surface treatment using a solution containing 2-vol% 3-methacryloxypropyltrimethoxysilane produced a higher bonding strength than non-treatment, MKV treatment and 4-META treatment. These findings suggest that pure titanium castings produced by this system have suitable mechanical properties, adaptability and adhesion to denture base resin, and is available for cast plate in clinical application.","PeriodicalId":12643,"journal":{"name":"Gifu Shika Gakkai zasshi = The Journal of Gifu Dental Society","volume":"17 1","pages":"280-309"},"PeriodicalIF":0.0,"publicationDate":"1990-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13289266","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}
