The purpose of this study is to observe histopathologic changes in the bilateral craniomandibular joints after allowing 6 weeks of consolidation by varying the amount of distraction in rabbit mandible. Eight rabbits weighing about 2 to 3kg were used. After corticotomy was performed on the left mandibular body between the first premolar and the second premolar region, a unilateral fixation device was placed. Then, a 7-day period was allowed without distraction of the device. The mandible was lengthened 0.5mm/day. Corticotomy and lengthening of mandible were not performed in control group. After the completion of the lengthening process, a 6-week-consolidation period was allowed. Then, the rabbits were sacrificed, and histologic examination of the craniomandibular joints was performed. Proliferative changes were observed in the craniomandibular joints in all groups. With the increasing amount of distraction, hypertrophy of the cartilage layer became more severe, bone formed was dense and enchondral ossification was clearly shown in subchondral bone. Hypertrophy of the cartilage layer was also seen in the non-distracted side as the distracted side in the experimental group. These results indicate that when physical force is applied constantly to joints, the proliferation of articular cartilage and bone formation are present. When more than 6 weeks of consolidation period is allowed at the time of performing distraction for more than 5mm, articular changes, especially, in the contralateral side should also be noted.

Aging is the single most important risk factor that increases susceptibility to many forms of diseases. As such, much effort has been put forward to elucidate the mechanisms behind the processes of aging and to discover novel compounds that retain antiaging activities. Korean red ginseng has been used for a variety of medical purposes in eastern countries for several thousands of years. It has been shown that Korean red ginseng affects a number of biological activities including, but not limited to, anti-inflammatory, anti-oxidative and anti-diabetic pathways. However, few studies have been performed to evaluate its anti-aging effects with an in vivo system. Here Drosophila melanogaster as an in vivo model organism demonstrates that Korean red ginseng tonic extends lifespan, increases resistance to starvation stress and prevents weight gain. This data suggest that Korean red ginseng may regulate organisms' metabolism in favor of extending lifespan.

Morgagni hernia is an uncommon finding in adult and rarer still in infants and children, adn they say that Morgagni hernia occur about one in every 300 diaphragmatic hernias diagnosed. This paper presents a 16 months old Korean male infant with symptomatic Morgagni's hernia in whom the diagnosis was established during the course of treatment of upper respiratory tract infection and who were operated successfully. This well nourished patient was admitted with the chief complaints of mid dyspnea, coughing and restlessness for 2 days. During treatment and investigation we detected a peristaltic sound in the right side lung field and confirmed it as Morgagni hernia by chest X-ray and barium swallowing. We performed corrective surgery through a midline supra-umbilical incision. As opened the peritoneum, transverse colon was gushed out, which suspected as herniated intestinal loop. After well mobilization of visible bowel, hernia sac was notified from the anterior portion or right crus of diaphragm. The hernia was reduced very easily. The patient made an uninterrupted recovery and on the 8th post-op. day, he went to home with symptom-free state. We made a brief literature review.

PURPOSE: This study was performed to be helpful in early diagnosis and treatment of the children with peptic ulcer disease. METHODS: The authors observed 36 children with peptic ulcer disease who had been admitted to Hanyang University Hospital during the 11 year 4 mont period from January 1981 to April 1992 retrospectively. The diagnosis was established in 33.3% by gastric endoscopy, in 25% by upper gastrointestinal barium study, in 11.7% by gastric endoscopy and upper gastrointestinal barium study simultaneously, and in 30% by emergency operation. RESULTS: 1) Age and sex incidence of chidlren with peptic ulcer disease(3 days to 16 years old) showed that males predominated in a proportion of 8:1 and 83.3% were 7 years of age or older. Under the age of 7, the incidence of gastric ulcer was greater than that of duodenal ulcer and above the age of 7 duodenal ulcer was 2.6 times more frequent than gastric ulcer. 2) The chief comlaints on admission were abdominal pain in 17 patients(47%), hematemesis or melena in 15 patients(25%), vomiting in 6 patients(16%). There was a tendency that abdominal pain also increased as the age increased. 3) Most common blood type among 13 patients with duodenal ulcer was Rh+O type(53.8%). 4) Of the 15 children who had gastrointestinal bleeding, 10(43.3% of duodenal ulcer) were doudenal ulcer and 4(33.3% of gastric ulcer) were gastric ulcer. Severe anemia(Hb<7g/dl) was shown in only 5 patients with duodenal ulcer. 5) According to the region of the ulcer, 20(86.9%) of 23 children with doudenal ulcer had ulcers in doudenal bulb and 8(66.7%) of 12 children with gastric ulcer had ulcers in antrum. 6) 18 children with duodenal ulcer, 7 children with gastric ulcer and 1 child with gastroduodenal ulcer had complications. Of the 26 children, bleeding occured in 10 children, perforation occured in 7 children and obstruction occured in one child. 7) 23 children were treated medically and 13 children were treated surgically. 11 patients received operation due to panperit unitis(perforation), 1 patients(71%) were treated medically, however, under 7 year of age, 5 patients(62%) received surgical treatment. Surgical methods used were primary closure(4 patients), vagotomy with pyloroplasty(1 patients), subtotal gastrectomy with gastrojejunostomy(7 patients) and antrectomy with gastroduodenostomy(1 patients). CONCLUSIONS: We conclude that it is important to diagnose early peptic ulcer disease in children, who have nonspecific symptoms and signs above mentioned, to prevent possible complications including failure to thrive.

PURPOSE: The purpose of this study was to investigate the level and factors influencing depression among nursing students. METHODS: The data were collected from nursing students attending 3 universities who expressed a willingness to participate in the study through a questionnaire which surveyed them about depression, stress, social support, self-efficacy, self-esteem, and wellbeing in May, 2012. The collected data from 235 nursing students were analyzed using a SPSSWIN 19.0. RESULTS: The mean score of depression (using MDI) among nursing students was 16.7, which denotes a minor depressive mood. 49.1% of variance with regard to depression among nursing students was explained by stress, self-esteem, wellbeing and self-efficacy. CONCLUSION: There is a need to develop a depression prevention program for nursing students and to reduce stress and increase self-esteem, wellbeing and self-efficacy in order to establish an effective program.

PURPOSE: The purpose of this study was to analyze the history of exposure to obscene material, and examine sexual attitudes and intercourse experience in order to develop an effective program for university students. METHOD: The data were collected in May, 2012 from 385 students attending 3 universities in Korea. An independent t-test and ANOVA were used to determine the differences with regard to sexual attitudes and intercourse experience according to general characteristics and history of exposure to obscene material. RESULTS: Sexual attitudes significantly differed according to timing of first exposure to obscene material (p<.001). Intercourse experience was significantly different according to timing of first exposure to obscene material (p=.016) and type of exposure to obscene material (p=.032). There was a negative correlation between first exposure to obscene material and sexual attitudes (p<.001), and a positive correlation between first exposure to obscene material and intercourse experience (p=.017). CONCLUSION: Results of this study indicate that history of exposure to obscene material should be considered as an important variable in managing the sexual health of university students.
