The patients visiting pediatric dental office have been being younger than the previous, and they were often combined with systemic disease. But, we aren't able to perform the verbal communication, because of their impediment and youthfullness. And, we can't carry out the behavior control via physical restraint, as the developed social structure and the attitude of children and their parents. So, the importance and concerning of conscious sedation using sedative medicine are increased by time and time. Among the various conscious sedation, Chloral Hydrate and Nitrous Oxide inhalation are most popularly used, and barbiturates, benzodiazepine, opioids and hydroxyzine are used often. But, these medications have some side-effects and adverse reactions, may be failed to sedate the children. And limited use of medically compromised patients, especially for ASA class III, IV or more dangerous patients. We, the Department of Pediatric Dentistry, Chosun University have met some dangerous situation due to unfavorable pharmacogenic reactions, but we can control the situation and get well healed results. The below results are common situations and their solutions during conscious sedation. 1. By the intravenous administration, thrombophlebitis is the most common side-effects, but it may be healed with time without any special treatment. 2. Under the definitive guidelines about conscious-sedation, we can perform a safe conscious sedation for ASA class III patients. 3. When adversed reaction of Benzodiazepine is occured, it could be cared effectively with benzodiazepine antagonist, named Flumazenil.

Revascularization of the pulp in a necrotic, infected immature tooth with apical periodontitis was attempting several years. Revascularization of partially necrotic pulp in an immature tooth is based on the concept that vital dental stem cells can survive pulpal necrosis. Revascularization procedure obtains longer and thicker roots in teeth with necrotic pulp diagnosis. Pulp revascularization for immature permanent molars can be possibly applied on cases having difficulty to use conventional root canal treatment due to abnormally thin root canal wall or severe root curvature. Also, when an uncooperative patient does not agree with sedative treatment the revascularization can be useful. And a patient with disability who is barely cooperative can be another indication of this treatment. In this case report, pulp revascularization using triple-antibiotics, metronidazole, ciprofloxacine and minocycline, was applied on the immature first permanent molar infected by caries.

In order to investigate pharmacological properties of New Woohwangchungsimwon Pill (NWCH) and Woohwangchungsimwon Pill(WCH), effects of NWCH and WCH on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in Mongolian gerbils. The histological observations showed preventive effect of NWCH and WCH treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by NWCH and WCH treatment. In contrast to what was seen with ATP, the lactate and lipid peroxide were both elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NWCH and WCH treatments. In central nervous system, NWCH and WCH had sedative effect in rotarod and spontaneous activity test, but no effects on the hexobarbital-induced sleeping time. And, NWCH and WCH had weak anticonvulsion effects in electric shock- and pentetrazol-induced convulsion test. NWCH and WCH increased the respiration rate, but decreased the respiration depth in rats. Furthermore, NWCH and WCH showed antistress effect. Our findings suggest that the pharmacological profiles of NWCH on cerebral ischemia and central nervous system are similar to that of WCH.

Anxiety disorders are one of the serious problems which need proper therapy devoid of side effects of presently available medicines. The present study evaluates the anxiolytic and sedative activity of leaf galls of Piper nigrum Linn. in Swiss Albino mice. The pet. ether, chloroform, ethyl acetate and ethanol extracts of leaf galls of Piper nigrum Linn were obtained by continuous soxhlet extraction. The prepared extracts were found to be safe up to 2000 mg/kg body weight of mice in the acute toxicity study. Each extract was assessed for anxiolytic activity in Swiss Albino mice by elevated plus Maze, open field test, rota rod test and phenobarbitone induced sleeping time test. In the Elevated Plus Maze test, the pet.ether extract and chloroform extract at a dose of 50 mg/kg b.w. orally, significantly (P < 0.01) increased the number of entries and time spent in open arm comparable with standard diazepam at the dose of 10 mg/kg. b.w. p.o. In the open field test, pet. ether extract (50 mg/kg b.w. p.o.) showed significant increase (P < 0.01) in ambulation and activity in the center. Chloroform extract (50 mg/kg b.w p.o.) was significant (P < 0.05) for both ambulation and center activity. Pet. ether extract (50 mg/kg b.w. p.o) also showed significant activity (P < 0.01) in rota rod test. All the results are comparable with standard diazepam at the dose of 1 mg /kg b.w, p.o. Moreover all the extracts showed significant (P < 0.01) increase in the phenobarbitone induced sleeping time among which pet.ether showed more prominent activity (36%) comparable with control. The results revealed that, the active pet.ether extract and chloroform extract of leaf galls of Piper nigrum Linn is worthwhile to develop the bioactive principle for anxiolytic activity.

Regular dental visit of disabled patients is an important strategy for maintenance of oral health because of the lack of awareness of oral care. But there is limited information about follow up period in disabled patients after dental treatment. The aim of this study was to investigate the pattern of dental visit and dental management of special care needs patients according to the types of disabilities. A total of 140 patients who received dental treatment at Seoul National University Dental Hospital from 2010 to 2012 were reviewed. Patients were divided 3 groups according to the types of disabilities (disorder of external physical function, disorder of internal organ, psychic disability). Patient's characteristic, dental treatment performed, follow up period and frequency were investigated. The mean follow up period was 28.2 months and average frequency of visit was 3.69 times per year. There was no difference in period and annual visit between 3 groups, but significantly difference in cooperation with medical hospital in affiliation. Regular check-up was the most common dental treatment in all groups. In psychic disorder group, the proportion of sedative treatment was significantly higher than other groups. The results of this study provide information necessary for treatment planning and dental management of disabled patients.

Management of children who show negative response to treatment was difficult. Usually the dentist used the restraintor sedatives for these children. Especially it is very difficult to management of definitely negative behavior patients who resist to ordinary sedative technics including psychosedation and various sedatives. These patients were managed with general anesthesia. Midazolam was used for sedation of non-cooperative pediatric patients and halothane for induce initial sleepness, If the patient shows negative response to management after 15 minutes of midazolam administration, used the halothane in 30 to 120 seconds for calm down the patient. After induce sleepness, cut off the halothane administration and maintain the sedation with $N_2O$ in 50-70 vol.% concentration. This technic reduce the toxity and untoward effects of major anesthetics. To compare the difference of sedation effect by dosage, dose of 0.2mg/kg and 0.3mg/kg were injected respectively. Though there's no statistical difference in duration and results between two dosage but show the increment of score with age, If the patients show positive response to management after midazolam administered. try to conscious sedation with nitrous oxide in 30 to 70 vo.% concentration. Nitrous oxide concentration was administered slowly according to their consciousness and response to treatment by increment or decrement. The success rate of conscious sedation were 21.2% in 0.2mg/kg and 30.3% in 0.3mg/kg. There's many factors in proceed of conscious sedation. The most important factors are age of patient and experience of children for dental care.

The aqueous extract of Chungsimyeonja-eum has been used to treat palpitation, anemia, chronic fatigue, hypertension, and stroke. It also possesses various pharmacological effects including hypotensive, blood circulating, sedative, anti-inflammatory, diuretic, and anti-stress activities. In the present results, the latency time of plantar test was decreased in the immobilization stress and incusion pain-induction group. However the paw withdrawal latency values were increased in the immobilization stress and incision pain-induction groups after treatment with the aqueous extract of Chungsimyeonja-eum. The c-Fos expression in the paraventricular nucleus (PVN), and 5-hydroxytryptamine (5-HT) and tryptophan hydroxylase (TPH) in the dorsal raphe were enhanced in the immobilization stress and incision pain-induction groups. However, the treatment with the aqueous extract of Chungsimyeonja-eum suppressed the immobilization stress and incision pain-induced increase of c-Fos, 5-HT, and TPH expressions. Here in this study, we have demonstrated the protective effects of Chungsimyeonja-eum on immobilization and incision pain-induced stress. The present study revealed that Chungsimyeonja-eum treatment diminishes immobilization and pain stress.

The root and rhizomes of Nardostachys chinensis belonging to the family Valerianaceae has been used for medicinal therapy in Korean traditional medicine. The parts have been especially used to elicit stomachic and sedative effects. Our previous studies reported that the water extract of N. chinensis has induced granulocytic differentiation inhuman promyelocytic leukemia (HL-60) cells. The Mitogen-activated protein kinases (MAPKs) are serine/threonine kinases involved in the regulation of various cellular responses, such as cell proliferation, differentiation and apoptosis. In this study, we investigated the signaling pathways on the HL-60 cell differentiation induced by N. chinensis. Activation of extracellular signal-regulated kinase (ERK) increased time-dependently in differentiation of HL-60 cells induced by N. chinersis. Activation of p38 increased slightly at 24 h after N. chinensis treatment, but activation of c-jun N-terminal kinase (JNK) was unaffected. Inhibitor of ERK (PD98059) significantly reduced NBT reduction activity induced by N. chinensis in HL-60 cells. In contrast, p38 inhibitor (SB203580) did not inhibit the cell differentiation. These results indicated that activaiton of ERK may De involved in HL-60 cell differentiation induced by N. chinensis.

Nardostachys chinensis (N. Chinensis) belonging to the family Valerianaceae have been used in traditional medicine to elicit stomachic and sedative effects. The present study investigated the effects of water extract of N. Chinensis in human lymphoma U937 cells. The proliferation of U937 cells was decreased by N. Chinensis. Anti-proliferative effect of N. Chinensis on U937 cells was associated with G0/G1 phase arrest, which was mediated by regulating the expression of p21 and p27 protein. In addition, the levels of CDK2, CDK4, CDK6, Cyclin D3, and Cyclin A were decreased, but Cyclin D1, Cyclin D2 and Cyclin E were essentially undetectable. N. Chinensis induced the differentiation of U937 as shown by increased expression of differentiation surface antigen CD11b, but not CD14. Taken together, these results demonstrated that N. Chinensis potently inhibits the proliferation of U937 cells via the G0/G1 phase cell cycle arrest in association with p21 and p27, and induces granulocytic differentiation.
