Background: The purpose of this study was to compare the availability of propofol and fentanyl (P + F) with diazepam and morphine (D + M) for intravenous conscious sedation during third molar surgery. Methods: Forty patients without systemic disease were operated under IV conscious sedation administered by either of the two techniques. Monitoring consisted of continuous observation of pulse rate, blood pressure, oxygen saturation, and the respiratory rate and were recorded every 15 minutes. Cooperation score was measured 5 and 15 minutes after induction of IV sedation. Following the operation, the surgeon and patients completed questionnaires including pain visual analog scale, amnesia, and side effects. Results: The P + F group was significantly more cooperative than the D + M group. The side effects of D + M group included pain on injection, nausea/vomiting and abdominal pain. The side effects of P + F group included talkativeness, nausea/vomiting, temporary apnea, pain on injection and vertigo. Conclusions: In this study, there were following benefits in the P + F group; more cooperative status and less pain perception. But respiratory depression developed in some patients.

Authors performed the immunohistochemical study with avidin biotin-peroxi- dase complex staining on the nail unit of the human fetus for determining the presence of keratin and prekeratin. Seven fetuses, ranging from 12 to 27 weeks in age, were examined. In all cases, the keratin and prekeratin were found in the epidermis of nail units, but not found in stratum corneum and nail plate. Keratin was located predominantly in suprabasal cells whereas prekeratin was located diffusely in the epidermis. Interestingly keratin and prekeratin were found as early as 12 week-old gestational period. There was no significant difference in presence of keratin and prekeratin.

Introduction: Mini-implant system is applicable to areas of narrow space and area requiring temporary loading support. The purpose of this study was to evaluate the clinical outcome of a mini-implant system as well as the application of mini-implant system in the dental clinical field. Materials and Methods: The patients who had been operated from Jan 2007 to Dec 2007 in the four dental facility including Seoul National University Bundang Hospital were enrolled. To evaluate the factors associated with the clinical outcome, the patients were classified according to gender, age, area of surgery, type of implant, diameter and length of the implant, and the purpose of the mini-implant system application. Results: From 147 implants, only three implants failed, one of them was for temporary loading. There were no serious surgical or prosthetic complications in this study. Conclusion: An analysis of the preliminary data revealed a satisfactory clinical outcome. However, more long-term evaluation of narrow ridge type as well as the patient’s satisfaction on the use of a provisional type mini-implant system is needed.

Subepidermal calcified nodules, consisting of solitary circumscribed deposits of insoluble calcium within the subepidermis, have generally been assumed to be idiopathic. As the disease is not associated with any systemic or cutaneous diseases, or any biochemical abnormalities, the pathogenesis is still unexplained, and it is thought to be a definite entity with only a characteristic histopathology. We report a 36-year-old female who has had subepidermal calcified nodules on both upper eyelids symmetrically for about 20 years. It is interesting that the lesions have xanthelasma-like appearance and are associated with syringomas. Excisional biopsy showed typical histopathologic and histochemical features of the sub epidermal calcified nodules.

Many dental surgeries including implant surgery, orthognathic surgery etc. have possibility of neurologic injury. As neutrosensory dysfunction has no definitive treatment modality and shows slow recovery, patients have discomforts and make the legal conflicts with surgeons. The purpose of this study was to survey the types and subjective evaluation of patients with neurosensory dysfuction after dental surgery. This study included 66 patients with postoperative neurosensory dysfunction who were operated at Seoul National University Bundang Hospital from Dee 2003 to Jun 2007. Male were 28 and female were 38. Age was from 17 to 74 years old. The results of subjective evaluation of neurosensory dysfunction were as followings. 1. The sites of the altered sensation were chin, lip, tooth, tongue and so on. 2. 40.7% of the patients didn’t explain accurately about their symptoms. 29.2% of the patients expressed anesthesia and 26.2% mild discomfort. 3. The altered sensation was expressed mostly in touching, mastication and speaking. 52.3% of the patients expressed that their symptoms always existed. 4. Neuropathic pain always existed in 44.6% of the patients. 48.3% of the patients suggested that pain was triggered by touching. Neuropathic pain always existed in 41.4% of the patients. 5. Patients showed negative responses on the question that they will take operations which cause the risk of neurosensory dysfunction in the future. The objective and subjective evaluation about the altered sensation after nerve injury nerver coincide. The subjective complaint can affect the result of treatment and daily life negatively.

Objectives : The purpose of this study was to compare cerebral biood flow between hypertensives and normotensives using transcranial doppler ultrasonography (TCD). Methods : I investigated cerebral blood flow of 72 hypertensives and 127 normotensives. To evaluate the cerebral blood flow, I measured the systolic peak velocity(Vs) and mean How velocity (Vm) of the middle cerebral artery(MCA), anterior cerebral artery(ACA), posterior cerebral artery(PCA), basilar artery(BA), and internal carotid artery(ICA) in the two groups using TCD. Result : 1. There was a decrease in the Vs and Vm of all examined vessels of hypertensives in comparison with normotensives. There was a significant difference in the Vs of ACA and Vm of ACA, PCA, ICA. 2. In males, there was a decrease in the Vs of ACA, PCA, ICA and Vm of MCA, ACA, PCA, ICA of hypertensives in comparison with normotensives. However, there was no significant difference in the Vs or Vm of all examined vessels. 3. In females, there was a decrease in the Vs and Vm of all examined vessels of hypertensives in comparison with normotensives. There was a significant difference in the Vs of MCA, ACA and BA and Vm of ACA, PCA and BA. 4. In 30-49 year-olds, there was a decrease in the Vs and Vm of all examined vessels of hypertensives in comparison with normotensives. There was a significant difference in the Vs of ACA and Vm of ACA. 5. In 50-69 year-olds, there was a decrease in the Vs of ACA, PCA, BA, ICA and Vm of all examined vessels of hypertensives in comparison with normotensives. However, there was no significant difference in the Vs or Vm of all examined vessels. 6. In 70-89 vests old. there was a decrease in the Vs. Vm of PCA, BA, ICA of hypertensives in comparison with normotensives. But, there was no significant difference in the Vs, Vm of all examined vessels. Conclusions : There was a significant difference in the cerebral blood now velocity between hypertensives and normotcnsives. These results suggest that blood pressure has influence on cerebral blood flow.

This study is designed to investigate the effects of Samul-Tang extract on the response of lactic dehydrogenase(LDH) release, cellular activity, lipid peroxidation, DNA synthesis and the changes of total protein of bovine pulmonary artery endothelial cells(PAEC) from hydrogen peroxide$(H_2O_2)$-induced injury. The results are as follows : 1. Samul-Tang significantly decreased $H_2O_2$-induced release of LDH from injured bovine PAEC. 2. Samul-Tang significantly repressed $H_2O_2$-induced cellular activity from injured bovine PAEC. 3. Samul-Tang significantly repressed $H_2O_2$-induced lipid peroxidation from injured bovine PAEC. 4. Samul-Tang significantly stimulated DNA synthesis in bovine PAEC. 5. Samul-Tang significantly repressed $H_2O_2$-induced changes of total protein volume from injured bovine PAEC. Above results suggest that Samul-Tang can protect bovine PAEC from $H_2O_2$-induced injury. These results can be effectively applied to the prevention and cure of cardiovascular and cerebrovascular diseases.
