본 연구의 목적은 클로르헥시딘 처리가 교정용 브라켓의 전단접착강도와 탈락 양상에 미치는 영향을 비교하는 것이다. 실험군으로 4주간 4회의 클로르헥시딘 바니쉬를 도포한 22개의 사람 소구치를 선택하였고, 대조군으로 아무 처리도 하지 않은 22개의 사람 소구치를 선택하였다. 모든 치아는 37%의 phosphoric acid gel로 부식시키고 교정용 브라켓을 같은 조건으로 부착시켰다. 전단접착강도의 측정을 위해 Instron universal testing machine(model 4466)을 이용하였고, 법랑질과 브라켓 표면은 SEM으로 관찰하였다. 결과의 분석은 t-test를 이용하였으며 결과는 다음과 같다. 1.클로르헥시딘의 법랑질 처리는 전단접착강도에 영향을 미치지 않았다. 2.클로르헥시딘으로 법랑질을 처리한 경우와 그렇지 않는 경우에 브라켓 탈락 양상에 차이가 없었다. 따라서, 클로르헥시딘으로 법랑질을 처리하여도 브라켓 접착에 유해한 작용이 없었고, 따라서 임상사용에 적합하다고 생각된다. The purpose of this study was to determine whether the application of chlorhexidine varnish affects the shear bond strength and failure pattern of orthodontic brackets or not. The experimental group consisted of 22 human premolars which extracted after chlorhexidine vanish application(4 times for 1 week interval) in vivo, and the control group consisted of 22 human premolars which extracted without any pre-treatment. After all teeth were etched with 37% phosphoric acid gel, metal orthodontic brackets (Q-3002, RMO, USA) were bonded to each tooth using auto-polymerizing orthodontic resin (Ortho-One, Bisco, USA) with the same bonding procedure. The shear bond strength was measured with Instron universal testing machine (model 4466, Instron Ltd., England), and the failure pattern of each bracket was examined with Scanning Electron Microscope (SM 840A, JEOL, Japan). The data were analysed statistically with t-test. The results were as follows : 1.Application of chlorhexidine varnish had no significant effect on the shear bond strength of the orthodontic bracket. 2.There was no significant difference in the failure pattern of orthodontic bracket between the experimental group and the control group.

Many motor activities of animals and human beings are a critical aspect for their survival. Although it has not been clearly understood how motor activities are produced, the idea that various motor programs exist somewhere in the central nervous system (CNS) is generally accepted. As evidence for existence of motor programs in the CNS, we may consider a simple, repetitive movement like walking. Walking does not require continuous thinking. Once it is initiated, it becomes quite automatic. If we try to control consciously our automated movement, then it becomes so unnatural. Edward Evart, a neurophysiologist, noticed in his monkey experiments that the arm muscle contraction for handle movement was preceded by the activation of neurons in the motor cortex that governs the arm movement. These experimental results may be taken as evidence for existence of central programs for movements in the motor cortex. Many other studies, however, have indicated that cerebellum is an important structure where motor program are stored. Potentially, motor programs may not be restricted to a particular site in the CNS. Instead, they may be distributed in the cortex. cerebellum and other neural structures such as the basal ganglia. To understand movements at the neural level, we should determine how movements are coded in the CNS. More specifically, we may have to reveal how neurons are interconnected and how they communicate with each other to ultimately produce movements. An important thing to realize before we attempt to answer these questions is the fact that there is no clear-cut boundary between voluntary and involuntary movements. Even in the voluntary activities such as tennis game, there are lots of involuntary components. Also, in many other cases, there is good evidence that perfect movements can be achieved involuntarily. Diving, which requires a rapid, coordinated control of eyes, arms, legs and other parts of the body, is a good example. To perform this type of movement, there must be a motor program. Cerebellum has been indicated as a key structure necessary for this kind of program. Cerebellum is known as a site involved in the control of independent limb movements, especially rapid, skilled movements. Such movements are initiated by neurons in the frontal association cortex, which control neurons in the primary motor cortex. Both the frontal association cortex and the primary motor cortex send information about intended movements to the cerebellum. Information from the somatosensory system, which informs about the current position and rate of the movement of the limbs-information necessary for computing the details of a movement-is also sent to the cerebellum. When the cerebellum receives the information that the motor cortex has begun to initiate a movement, it computes the contribution that various muscles will have to make to perform that movement. The result of this computation is sent back to the motor cortex. Thus, the information from the cortex enables the cerebellum to modify the ongoing movement initiated by the frontal cortex. The capacity of the cerebellum to fine-tune motor drive generated in the motor cortex may be enhanced by training. In this case, the training will influence the involuntary components of movement.

Acute paranasal sinusitis is frequently encountered in medical practice and is managed without complication in the majority of cases. But, paranasal sinus inflammation may invade the orbit because paranasal sinuses are close to the orbital wall. Orbital inflammation is the most common complication of acute paranasal sinusitis and lead to blindness, intracranial complications, and death. Orbital complications of acute paranasal sinusitis are thought to arise when the infection spreads to the orbit by direct extension, local thrombophlebitis, or less commonly infected thromboemboli along valveless venous connections. Diagnosis of orbital complication requires a thorough history and physical examination, including an ophthalmologic evaluation. Computed tomography is frequently required as an adjunct in assessing the clinical manifestations of advanced disease, and it can assist the physician in surgical planning if required. Most orbital infections respond to medical therapy. Some cases require surgical intervention. We report three cases that have required surgical intervention, with a review of related literatures.

Background: Pain is major problem regarding quality of life in children undergoing tonsillectomy. Preemptive analgesia by medicine given before commencement of surgery is a new recommended for relief of pain during and after operation. We compared intra-and postoperative analgesic and recovery characteristics of tramadol, meperidine given at induction of anesthesia in 40 ASA I or II children undergoing tonsillectomy with or without adenoidectomy. Materias and Methods: Fourty children aged 4-7 years undergoing tonsillectomy with or without adenoidectomy were randomly assigned to receive either tramadol 2 mg/kg (group 1) or meperidine 1 mg/kg (group 2) at induction of anesthesia. Thiopental sodium (5 mg/kg) and rocuronium (0.6 mg/kg) were used for the induction of anesthesia, and it was maintained with sevoflurane in N₂O/O₂50/50 via an endotracheal tube. Pain assessment was done by facial pain scale. Agitation scores, time to recovery of spontaneous respiration and the incidence of postoperative nausea and vomiting. Heart rate and mean arterial pressure was recorded at regular intervals. Results: Facial pain scale scores were increased in group 1 at 10 and 20 min in recovery room. There was no difference for agitation scores in the two groups. Intraoperative mean arterial pressure (15th min) were found to be higher in group 1. The time to recovery of spontaneous respiration was delayed with group 2 compared with group 1. The incidence of nausea and vomiting was not statistically differed between groups. Conclusions: Meperidine was more effective for pain relief than tramadol after tonsillectomy in children.

Marine resources have various biological activities and their constituents are more novel than those of land organisms. Several biologically active constituents have been found in marine organisms. Recently, many studies have reported that marine animals (MAs) can be used as functional ingredients in functional foods or nutraceutical due to their health benefits. However, no studies have extensively investigated the cosmeceutical activities of MAs extracts. Here, 70% ethanol extracts of 38 MAs were investigated for their activities of whitening and anti-aging properties for use as materials in novel cosmeceuticals. Anti-aging activities were determined by skin aging-related enzyme activities (anti-collagenase, anti-elastase, anti-hyaluronidase) and whitening activities (anti-tyrosinase, anti-3,4-dihydroxyl-L-phenylalanine [DOPA] oxidation) evaluated by colorimetric method. Among the 38 MAs, we found that Urechis unicinctus and Petrosia corticata extracts showed the strongest inhibitory effects against tyrosinase and DOPA oxidation, respectively. Our results additionally showed that Protankyra bidentata extract might provide a major source of anti-hyaluronidase and anti-elastase; meanwhile, anti-collagenase effects were similar in most MAs. Overall, these results suggest that extracts of marine animals have potential as a tyrosinase, collagenase, elastase, and hyaluronidase inhibitors. Taken together, MA resources could be considered as a novel cosmeceutical agent to be applied in cosmetic industry.
