數種의 縫合物이 Vitamin C 缺乏 및 過多投與 Guinea Pig 皮膚組織에 미치는 影響

卞相吉,卞鍾秀 慶北大學校 齒科大學 1984 慶北齒大論文集 Vol.1 No.2

The purpose of this study was to observed and compare the reaction of suture materials, silk, chromic catgut (multifilament), nylon, wire (monofilament), in applying to skin tissue of guinea pig after given overdose & deficiency of vitamin C using half-circle cutting needle, paralleling at regular distance, histopathologically. The 40 animals, average weight 400-600gm, were divided into 3 groups: one control group received 5mg ascorbic acid spplement per day on each (15 animals), experimental group I is scorbutic condition group (15 animals) and experimental group Ⅱ received 100mg ascorbic acid supplement per day on each (10 animals). The all groups received vitamin C deficient diet from 7 days of experiment to the finally. Each of the experimental and control animals was sacrificed on the 1st, 4th, 7th, 14th, 21th day after implantation of suture materials. The all specimens taken were fixed in 10% formalin solution for 24 hours and then embedded in paraffin for the slide section. Each specimen was strained at hematoxylin-eosin strain. The following results were obtained. The healing process around a implantation space of suture materials showed more rapidly healing in the groups received a ascorbic acid than under scorbutic condition, and that process in the over dosage of ascorbic acid caused more effective reaction. In the group received a overdose ascorbic acid, a primary healing process began to show more rapid reaction, but no significant difference was found on the 14th day after implanatation. The monofilament suture materials showed milder reactions than the multifilament suture materials and then silk showed more severe tissue reaction than chromic catgut. The healing process around the implantation space of suture materials showed that a wire, which the stability of implantation itself was insufficient, caused the worst reaction, silk and chromic catgut worse in turn and nylon showed the best tissue reaction. The chromic catgut, the absorptive suture material, showed a rapid absorption from the 14th day, and on the 21th day nearly complete absorptive impression was found.

저자 등은 8년간 dilantin의 복용으로 상하악간에 전반적인 치은비대증을 나타낸 환자를 치은절제술과 치은성형술을 시행하고 계속적인 치석제거와 치은연하소파술을 시행하여 재발됨이 없이 심미적으로나 기능적으로 만족한 결과를 얻었기에 이에 보고하는 바이다. Enlargement of the gingiva caused by phenitoin an anticonvulsant used in the treatment of epilepsy, occurs in some of the patients receiving the drug. Its incidence varies from 3 to 62 percent, with the greater frequencies in younger patients. The hyperplasia is usually generalized throughout the mouth, but is more severe tendency in the maxillary and mandibular anterior regions. 18 year old male patient was admitted to our Department of Dentistry with the complaint of generalized painless gingival swelling. After the consult of the N.M. and laboratory study, the gingivectomy and gingivoplasty was performed. The periodontal pack and tin foil was applied on the attached gingiva to protect a surgical site and bleeding control. We obtained a good result of improved esthetics and function.

This experimental study was carried out to evaluate the effect of As-Ga laser irradiation on the regeneration of an injured peripheral nerve in rabbits electrophysiologically and through the retrograde axonal transport of horseradish peroxidase(HRP). The experimental animals were divided into a normal group, a laser irradiation group, and a non-irradiation group, and each was subdivided in 1, 3, 5 and 9 week groups according to the time lapsed after the nerve injury. Under general anesthesia, the mandibular branch of the facial nerve was exposed, and a pair of stimulating electrodes and EMG recording electrodes were placed on the trunk of the facial nerve and the orbicularis oris muscle of the lower lip, respectively. After measurement of the threshold intensity of the facial nerve and the recording of the EMG, a crushing injury was given to the nerve. An irradiation by As-Ga laser was performed for 10 minutes everyday for one week. After the experimental period, the electrophysiological parameters were determined again, and a 50% HRP solution was applied to the nerve ending for 72 hours. The numbers of HRP - positive neurons were calculated under a light microscope and the EMG was analyses with a computer. 1. In the 3 and 5 week groups, the numbers of HRP - positive neurons in the facial nucleus were significantly increased in the laser irradiation group. 2. The treshold intensity of the facial nerve significantly increased after nerve injury, and a rapid recovery of the threshold intensity was observed in the laser irrdiation group. 3. However, recovery of the conduction velocity of the injured facial nerve was not significantly different between the laser irradiation groups and the non-irradiation groups.

The fibroma is a benign neoplasm composed of fibroblasts and collagen derived from the mesenchyme or fibroblasts of bone. The lesions appear to be located predominantly in the posterior region of the mandible and also be involved in maxilla. Its symptoms may be abscent except for awareness of a painless swelling. In this case surgical enucleation of well encapsulated solid tumor on left facial area was performed under general anesthesia.

This is a case report of the orthognathic surgery improved true mandibular prognathism by sagittal split ramus osteotomy with intraoral approach. The sagittal split ramus osteotomy was made on the lingual and buccal aspects and was then connected along the anterior border of the ascending ramus. After the mandible was displaced to the backward direction, direct bone wiring near the anterior border of ascending ramus was applied for stabilization. For preventing the postoperative swelling & hematoma, hemovac was inserted. There were no severe complications except postoperative swelling and edema for 2 days. Intermaxillary fixation was maintained for 8 weeks and postoperative orthodontic treatment was performed for 3 months.

영남대학교 의과대학 부속병원 치과 ·구강외과에 상 ·하악 전돌을 가진 환자가 안모 추형으로 인한 심미적 장애와 상악 전치부 치간이개 및 하악전치부 치열부정을 주소로 내원하였다. 안면치조기형에 대한 육안적평가, 방사선학적검사, 두부계측사진분석 및 진단 모형분석 등 다각적인 분석 결과 상 ·하악 치조 전돌증으로 진단을 내렸으며, 내원 당시 본 환자는 전반적으로 치주병학적 문제점을 가지고 있었고 개인적으로 군입대라는 특수상황하에 있었기 때문에 치주조직에 대한 손상을 최소로 하면서 치료기간을 최대한 단축시킬 수 있는 치료계획을 세웠다. 상하악 전치부에 대한 술전교정 치료 후 상악골은 전방부분절 골절단술로 후방으로 이동시키고 하악골은 전방부분 치근단 하방 골절단술로 후하방으로 이동시키므로서 상하악 전돌증에 대한 악교정 외과적 처치를 하여 좋은 결과를 얻었기에 이에 보고하는 바이다. The authors treated a case of bimaxillary dentoalveolar protrusion corrected by anterior segmental osteotomies: As presurgical treatment & process, closing of the upper anterior spacing with fixed appliances was worked out, cephalometric prediction & model surgery was done, and fabrication of intra-arch acrylic resin splints were made. It was not necessary to make an intermaxillary fixation with wire after surgery. Only intramaxillary fixation of anterior retracted mobile segment with resin pkate was required for 8 weeks. After surgical treatment, leveling of the upper and lower arch with rectangular arch wire were accomplished as the intrusion of anterior teeth proceeded. We will continue to improve the class Ⅱ molar relationship by using class Ⅱ elastics and have a good occlusion through the orthodontic treatment.

김성호,남성만,변상길,윤신영,홍성식,Kim, Seong Ho,Nam, Seong Man,Byeon, Sang Gil,Yun, Sin Yeong,Hong, Seong Sik Korean Chemical Society 2000 Bulletin of the Korean Chemical Society Vol.21 No.4

A simple and inexpensive colorimetric spectrometer for determining total cholesterol has been developed,comprising a diode laser as the light sourcoptical fibers for the light guide and a photodiode as the detector.The stabilty and performance of the new system was investigated by obtaining the calibration curve for stan-dard cholesterol solutions. The total cholesterol in humanserum was also measured by the analyzer and com-pared with the value obtained by a conventional spectrometer. The results showed that the developed spectrometer was useful for the determination of cholesterol levels. The visible diodelaser used in the study exhibited good spectroscopic and operational properties for colorimetric absorption spectrometry and could be a key component for the development of a simple and economical analyzer.
