The purpose of this study was to examine the relationship between the Dentocult SM and LB scores of students and their DMF rate. The subjects in this study were 134 special school students in south Gyeong-sang province. After they were tested to find out their, they received tooth brushing education and preventive treatment. The test, education and treatment were all conducted from March 17 to April 9, 2008. Their oral state was checked and recorded by using a mirror and explorer, and then the data on oral state were analyzed to their DMFT, DT, FT and MT rates. All the collected data were analyzed with SPSS 15.0 for Windows program, and independent-samples t-test, one-way ANOVA and crosstabs analysis were implemented to see what differences their disability type, gender, Dentocult-SM scores and Dentocult-LB scores made. The findings of the study were as follows: 1. As for connections between disability type and DMFT rate, the students with mental retardation were similar to the other students in that regard. The mentally retarded students had higher DT and FT rates than the other students, and the MT rate of the latter was higher than that of the former. 2. Concerning the relationship of gender to DMFT and DT rates, the girls had larger DMFT and DT rates than the boys, and the FT and MT rates of the boys were higher than those of the girls. 3. As to links between Dentocult SM scores on the tongue and DMFT, the students whose bacteria was mildly activated had the highest DMFT rate, and the students who had a severely activated bacteria had the highest DT and FT rates. Those who had a moderately activated bacteria had the highest MT rate. 4.Regarding the connection of Dentocult SM scores on maxillyright molar to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a mildly activated bacteria had the highest MT rate. 5.Regarding the connection of Dentocult SM scores on maxillyleft molar to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a mildly activated bacteria had the largest MT rate. 6. Regarding the connection of Dentocult SM scores on mandibularright molar to DMFT and DT, FT rates, the students whose bacteria was severely activated had the highest DMFT and DT, FT rates. Those who had a moderately activated bacteria had the highest MT rate. 7. Regarding the connection of Dentocult SM scores on mandibularleft molar to DMFT and DT rates, the students whose bacteria was mildly activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a moderately activated bacteria had the highest MT rate. 8. Regarding the connection of Dentocult LB scores to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had a moderately FT rate, the students who had a mildly activated bacteria had a mildly MT rate.

Purpose: Toxic alcohols are responsible for accidental and suicide motivated poisonings, resulting in death or permanent sequelae for the afflicted patients. Major therapeutic modalities in these cases include treatment with alcohol dehydrogenase inhibitors and extracorporeal elimination. There have been a number of case reports of toxic alcohol intoxication in Korea. The purpose of this study was to review the clinical characteristics of patients suffering toxic alcohol intoxication. Methods: We retrospectively reviewed the medical records of patients who presented with toxic alcohol intoxication at 8 emergency departments (ED) from Jun 2005 to Nov 2011. Patients who ingested methanol, isopropyl alcohol, ethylene glycol, and other alcohols except ethanol, were included in this study. The clinical characteristics of these patients were analyzed to include anion and osmolar gap, and estimated concentration of alcohol in the body. Results: During the study period, 21 patients were identified who had ingested toxic alcohol (methanol; 12 patients, ethylene glycol; 9 patients). At ED arrival, the mean anion gap was $18.7{\pm}6.9$ and the osmolar gap was elevated in 13 patients. Oral and IV ethanol were administrated to 11 patients in order to inhibit alcohol dehydrogenase. Extracorporeal elimination procedures such as hemodialysis were performed in 9 patients. There were no fatalities, but the one patient suffered permanent blindness. Conclusion: This study found that ethylene glycol and methanol were the substances ingested which produced toxic alcohol intoxication. The patients presented with high anion gap metabolic acidosis and were typically treated with oral ethanol and hemodialysis.

This is preliminary report on anthrax epidemic occurred in an island with about 100 residents. Since 1982 there had been sudden deaths among all kinds of domestic animals including cattle, dogs, ducks, chicken and goat but only a few among cats in an isolated island about three hours distance away by ferry boat from Mokpo city. From 1986 through 1988 nine human deaths and four patients occurred, which made the government intervene for investigation on June 25 1988. The epidemiological investigation consisted of interview survey and medical examination, medical record analysis, laboratory work to isolate the pathogens under the direction of hypothesis derived from the study and further confirmation of the pathogens by international institute. The summarized results are as followings: 1. According to the interview survey there were many deaths among domestic animals usually in cold and dry season such as January through March and September through November; 36 heads of cattle leaving one head, more than 40 hogs(all), hundreds of chicken leaving few alive, goats that had taken home from mountain and two or three cats out of around 40 had sudden deaths from 1982 till 1985, when the residents stopped to purchase and take them into the island anymore. Also there were eleven persons who had experienced the similar syndrome complex to those of admitted and expired patients and four of them revealed typical chest X-ray findings; from one of these four patients(Rho) B. anthracis is isolated. 2. Medical record on patients who had been admitted, showed common characteristics of the disease course. On admission they had either gastrointestinal or upper respiratory infection symptoms which invariably progressed to septicemic nature with pulmonary interstitial infiltration and mediastinal widening/bulging, and then to deadly acute respiratory distress syndrome. At the end stage chest X-ray revealed multiple bullous emphysema. One of another characteristics was oral ulceration with bleeding occurred in about 50% of the patients. Laboratory test results in common were leukocytosis with left shift and abnormal liver and kidney functions, particularly at the later stage of the illness. 3. Epidemiological characteristics was striking in that both mortality and incidence rates were high: the mortality rate was 8.7% average, male being three times higher than females but there was no distictive clustering by age group. The incidence rate for both sexes was 28.2% and there was no sex difference although a tendency of higher incidence among older ages was noticed. The highest mortality and incidence were observed in Won village where the first death of animal occurred and with the highest frequency among three villages of the island. 4. Among twelve bacilli species isolated from various specimens, two strains, one from patient and the other from soil where the recently died cow is hurried, were confirmed as B. anthracis by Pasteur Institute and CDC of USA(strain from soil). CDC reported that the strain did not produce capsule in bicarbonate media but reacted with the bacteriophage and one of five sera taken from the patients. Mode of transmission as well as incubation period of the agent has not been established yet, which needs further investigation in relation to the antigenic structure of the variant when it is confirmed.

Dentists have been striving to find ways to relieve patients' pain and discomfort. The prestige of dentists is made up of dentists' self-sacrifice, academic research and pursuit of patients' well being. However, nowadays the dentists' prestige has been lost and practice on humanity has merely existed. At this time, it is meaningful to shed new light on life of a pioneer in Korean dentistry and take some time for self-examination. Today, we are going to look into life of Dr. Jong-Suh Ahn and his achievements in Korean dentistry. In 1925, Dr. Ahn Jong Suh graduated from KyungSung Dental school as a first graduating class. Then, he learned advanced dentistry at Severance Hospital and in April of 1932 as a young dentist with full of potentials, he opened his dental clinic in Tianjin, China. As an awakening Korean, in 1925 he organized an association of Korean dentists, called HanSung Dental Association and worked as a secretary to manage general affairs. Han Sung Dental Association later became today's Korean Dental Association. On December 9th, 1945, he founded ChoSun Dental Association. He accomplished great deals during his five consecutive terms as a chairman and held other important positions with prestige to lead and expand the scope Korean dental association. There were three other successors to Dr. Ahn as the presidents of Dental Association. Dr. Yong-Jin Kim had a great interest in internal affairs and dental materials. Dr. Myung-Jin Park was active in scientific affairs and Dr. Dong-Chan Han focused on smooth operation of the association. From 1945 to 1963, Dr. Ahn submitted important agendas such as dentist's qualification, scientific and academic affairs, general affairs, dental materials, public oral health, and dental administration to Dental Association's general meeting and central committee. Dr. Ahn overcame hardships of Japanese imperialism, celebrated independence of Korea, experienced 6.25 Korean War and lived through evolving Korean dentistry in 1960s. Dr. Jong-Suh Ahn, who showed the prestige of dentist and expanded the scope of dental association, is exemplary to all dentists.

Chitosan has been known as a wound healing agent. The purpose of this study was to evaluate the biocompatibility and guided bone regenerative effect of chitosan and chitosan-cellulose membranes. The effects of chitosan and chitosan-cellulose membranes on the growth and survival of human periodontal ligament cells were examined by rapid colorimetric MTT(tetrazolium) assay, and the tissue response and resorption pattern were observed by implanting the membranes into the subcutaneous tissue of the back of rats for 6 weeks. To evaluate the guided bone regenerative potential of membranes, the amount of newly formed bone in the rat calvarial defects(8mm in diameter) was measured by histomorphometry and radiomorphometry 1,2 and 4 weeks after implantation of membranes. Chitosan and chitosan-cellulose membranes showed no adverse effect on the growth and survival of human periodontal ligament cells. When membranes were subcutaneously implanted, inflammatory reaction was observed at 1 week and which gradually subsided 2weeks after implantation. Membranes remained intact throughout the experimental period of 6 weeks. Radiomorphometric analysis of the craniotomy sites revealed that chitosan and chitosan-cellulose membrane implanted sites showed increased radiopacity over control. Statistically significant differences with control were found in chitosan-cellulose membrane implanted group at 2 and 4 weeks, and chitosan membrane implanted group at 4 weeks(P<0.05). Histomorphometric data indicated a pattern of osseous healing similar to radiomorphometric analysis. There was a statistically significant difference between control and chitosan-cellulose membrane implanted group at 4 weeks(P<0.05). These results implicate that chitosan and chitosan-cellulose membrane might be useful for guided bone regeneration.

Purpose: The objective of this study was to investigate the effect of a dietary flavonoid, kaempferol, which has been shown to possess antiallergic, anti-inflammatory, anticarcinogenic, and antioxidant activities on the periodontium by histomorphometric analysis and on gingival tissue matrix metalloproteinase-1 (MMP-1), MMP-8, and tissue inhibitor of metalloproteinase-2 (TIMP-2) by biochemical analysis of rats after experimental periodontitis induction. Methods: Sixty Wistar rats were randomly divided into six groups of ten rats each, and silk ligatures were placed around the cervical area of the mandibular first molars for 15 days, except in the healthy control rats. In the experimental periodontitis groups, systemic kaempferol (10 mg/kg/2d) and saline were administered by oral gavage at two different periods (with and without the presence of dental biofilm) to all rats except for the ten non-medicated rats. Alveolar bone area, alveolar bone level, and attachment level were determined by histomorphometric analysis, and gingival tissue levels of MMP-1, MMP-8, and TIMP-2 were detected by biochemical analysis. Results: Significantly greater bone area and significantly less alveolar bone and attachment loss were observed in the kaempferol application groups compared to the control groups (P<0.05). In addition, gingival tissue MMP-1 and -8 levels were significantly lower in the kaempferol application groups compared to the control groups and the periodontitis group (P<0.001). There were no statistically significant differences in TIMP-2 levels between the kaempferol and saline application groups (P>0.05). Conclusions: Kaempferol application may be useful in decreasing alveolar bone resorption, attachment loss, and MMP-1 and -8 production in experimental periodontitis.

Purpose: Breastfeeding is the optimal method for feeding a newborn. But insufficient breast milk is the major reason why mothers give up breastfeeding. Herbal galactagogues have been used increasingly to treat postpartum hypogalactia. This study examined the effect of an herbal tea containing Chrysanthemum indicum, as the main ingredient, on milk production in lactating rats. Methods: The herbal tea contained C. indicum (27%), Foeniculum vulgare Mill (21%), Pimpinella anisum (18.2%), Carum carvi (16.1%), Urtica dioica (14.7%), and Gardenia jasminoides (3%). Sixteen lactating Sprague-Dawley (SD) rats were divided randomly into 2 groups, the normal control group (NC; n = 8), and the galactagogue herbal tea group (GHT; n = 8) for 7 days. Lactating rats were administered the decoction of an herbal galactagogue mixture by oral gavage or the same amount of distilled water and milk production was assessed by measuring the pups' weights during the suckling period. The blood concentrations of prolactin, cortisol, oxytocin levels and mammary gland tissues were examined to assess the effects of the galactagogue. Results: Milk production was 9.2% higher in the GHT group given the herbal tea than in the NC group and the difference was statistically significant. The cortisol level in the GHT group was 17.2% higher than the NC group. The herbal tea containing C. indicum increased the size of the alveoli epithelium cells and the mammary lobe. Conclusion: The present study revealed the potential of herbal tea containing C. indicum to enhance milk production in postpartum SD rats.
