PURPOSE: In adriamycin(ADR)-induced cardiomyopathy, several different mechanisms are suggested. However, little information is available regarding the role of apoptosis. In the present study, we examined the induction of apoptosis on ADR treatment and anti-apoptotic effects of probucol, a lipid-lowering drug, and we also studied the changes of bcl-2 expression in order to see the molecular mechanisms underlying the effect of probucol. METHODS: Cardiac myocytes were isolated from 3-day-old rats, and cultured in low(1 pM) or high doses(10pM) of ADR for 24 hours. Probucol(50 pM) was added 30 minutes before ADR administration. Apoptosis was determined by TUNEL staining, and bcl-2 expression was estimated by immunocytochemistry. RESULTS: The number of TUNEL-positive cells significantly increased in both groups treated with ADR. However, anti-apoptotic effect of probucol was evident only in low dose. In addition, the expression of bcl-2 was significantly increased only in the low-dose ADR treatment group and its expression was inhibited by pretreatment of probucol. CONCLUSION: These results suggest that apoptosis might play an important role in ADR-induced cardiotoxicity, and ADR-induced apoptosis was partially prevented by pretreatment of probucol. And ADR-induced apoptosis was not related with depression of bcl-2. Additionally, inhibition of bcl-2 gene expression of low-dose ADR treatment group by probucol suggests that another cell survival mechanism could be implicated in the action of probucol.

The skin defects or sensory impairment of the fingers, especially at the critical area for prehension(tips of thumb, index and middle fingers) should be reconstructed for the better function of hand. In our department, we performed neurovascular island pedicle flap transfer for the purpose of reconstruction of sensibility and skin defect simultaneousely to the critical area. 1. Since 1978, we had performed neurovascular island pedicle flap transfer in 14cases, among which 9 cases were followed for more than one year. 2. The operation was performed for the reconstruction of thumb in 8 cases, and index in 4 cases. The most common cause of injury was crushing by machine(8 cases). 3. The island flap was transferred from middle finger(9 cases) and from ring finger(4 cases). 4. Recovery of the protective sensation at the recipient sites was good or fair after one year, but reorientation and two point discrimination were poor. 5. Cold intolerance was developed in 3 cases and callosity was formed in 2 cases. 6. In all cases, the transferred flaps were good in circulation status and durability. 7. It is considered that the neurovascular island pedicle flap is an accepted method of restoring skin coverage as well as sensation to a localized tactile area in the hand.

5.Evaluation of a Nutrition Education Website for Children.
Korean Journal of Community Nutrition 2006;11(2):218-228
This study was carried out to evaluate the usefulness and the effectiveness of the nutrition education website 'ifood (http://ifood.or.kr)' for children. A total of 262 children (5th and 6th graders) participated in the self-education program using the website which consisted of 4 sessions every two weeks. In each session, they were asked to answer some questions on the comprehensiveness of each topic while navigating the website. Nutrition knowledge (20 items), dietary attitudes (7 items), and dietary behaviors (10 items) were evaluated using questionnaires before and after the education. After the education, the usefulness and readability of the website was also evaluated. Most (97.2%) of the responders reported that the education using this website was helpful, 97.3% thought that the contents were reliable, 90.1% responded that the contents were easy to understand, and 88.8% answered that they would revisit 'ifood'. The menus they liked best were "Interesting games" for 35.8%, "How can I cook?" for 17.8%, "How can I become slim" for 16.4%. This website might be more attractive by providing a "greater variety of contents in detail", "more music, motion pictures and images", "more interesting games". After the education, there was a significant increase in nutrition knowledge scores from 10.9 to 13.1. Although the total scores of dietary attitudes and dietary behaviors did not improve, there was a significant increase in each of some questions. These results showed that "ifood", a nutritional education website, was desirable in reliability, aesthetics and enjoyability, and was effective in improving nutrition knowledge and some of dietary attitudes and behaviors in children.

The purpose of educational effort for career planning in medical school is to help students develop identity as a competent physician and to assist them in selecting their future career properly. To achieve the above, the specific education programs for career plan together with an individual counselling and problem solving approach are required. We proposed an education model for career planning in Gachon Medical School which would be directed by cooperative system consisted of medical school, faculty mentor and student counselling office. Career education should not be limited to several lectures or short-term counselling, but it requires a continuous and consistent program implemented throughout 6 years of medical school life. At the same time, an opportunity to explore future career and to consult their problems in accord with needs and characteristics of individual students must be provided. Further study should be directed to examine the usefulness and problems of this education model. In addition, a persistent attention to the problems in career planning of medical students and efforts to solve them is needed.

Objective To compare the curative effect and biomechanical performance of cannulated compression screw (CCS) and dynamic hip screw-blade (DHS-B) in the treatment of patients with femoral neck fracture.Methods Between February 2010 and February 2014,102 patients with femoral neck fracture were treated with CCS or DHS-B at our department.They were 54 males and 48 females,aged from 15 to 86 years.There were 30 subcapital fractures,51 transcervical ones and 21 base ones.CCS was used in 60 patients and DHS-B in 42.In-hospital data were collected retrospectively to compare the curative effects in 2 groups.Furthermore,femoral neck fracture models were established using 12 adult cadaveric femoral specimens.The 12 models were randomized into 2 equal groups (n =6).Group A was subjected to fixation by 3 CCSs and group B to fixation by DHS-B.The 2 groups were compared in terms of axial loading test,rotation test and destructive axial loading test.Results The operation time (59.4 ± 20.2 min),incision size (4.1 ±0.6 cm) and intraoperative blood loss (25.9 ±9.9 mL) in the CCS group were significantly less than those in the DHS-B group (88.6±22.9 min,12.1 ±1.2cmand 156.7±107.1 mL) (P <0.05).The Harris hip score for the DHS-B group (91.9±9.8) was significantly higher than that for the CCS group (87.2 ± 9.2) (P < 0.05).There were no significant differences between the 2 groups in hospital stay,partial weight-bearing time,or postoperative complications (P > 0.05).At 500 N vertical loading,the stress values at both medial and lateral sides of the femur in group A were significantly smaller than those in group B (P < 0.05).There were no significant differences between groups A and B in the average sinking displacement of femoral head or the torque at a torsion angle of 6° (P > 0.05).The maximum load in group A (2,135 ±120 N) was significantly smaller than that in group B (2,986 ± 98 N) (P < 0.05).Conclusion In treatment of femoral neck fracture,DHS-B fixation is obviously superior to CCS fixation,because the former is in better agreement with the femoral biomechanical property,and performs better in anti-rotation and anti-compression,leading to better functional recovery of the affected hip.

In Korea, cases of direct insertion of foreign bodies into the rectum are rare in the literature. Most cases of rectal insertion of foreign bodies are associated with sexual acts and psychiatric disorder such as schizophrenia. Objects inserted into the anus are usually blunt and shaped like the male genitalia. The removal method can be varied depending on the size and shape of the foreign object, its anatomical location, and the accompanying complications. In cases wherein attempts to remove the object fail or there are rectal perforation and peritonitis complications, immediate laparotomy may be required in order to prevent serious complications such as sepsis. Here, we report on a case of rectal perforation and peritonitis due to insertion of a foreign body in a middle-aged patient, with a literature review. He inserted a sharp pig backbone in his rectum and he only had depression. The patient underwent a Hartmann's operation as well as psychiatric counseling and treatment. Thus, after removal of foreign bodies, psychiatric counseling and treatment should be carried out in order to prevent similar accidents and to minimize the need for trauma medicine.

OBJECTIVES: The purpose of the study was to examine the relationships between temperament and character dimensions and family environments, and to investigate the influences of those factors on the antisocial personality traits in delinquent adolescents. METHODS: The subjects consisted of 160 male adolescents detained at the public prosecutor's office on the suspicion of crimes. To assess personality dimensions and family environmental factors, the Temperament and Character Inventory(TCI) and the Family Environment Scale(FES) were completed. Antisocial personality traits were assessed by the number of antisocial personality disorder symptoms of the Personality Disorder Questionnaire-Revised. RESULTS: Most of the TCI dimensions except Reward Dependence(RD) were highly correlated with the subscales of FES. Among temperament dimensions, Novelty Seeking(NS) and Persistence(P) were significantly affected by Organization, and Harm Avoidance(HA) was influenced by Expressiveness of FES. Self-Directednss(SD) was best predicted by Organization and Achievement-Orientation. While the Independence had significant effect on Cooperativeness, Expressiveness and Achievement-Orientation best predicted the level of Self-Transcendence(ST). On factor analysis, NS, HA, SD and ST were allocated to the same factors with subscales of FES. The level of antisocial personality trait was best predicted by NS, P and SD scores of TCI, and conflict subscale scores of FES. CONCLUSION: The findings of this study suggest that not only the character dimensions but also the temperament dimensions have close relationships with family environmental factors, and that the antisocial personality traits of delinquent adolescents may developed by the interaction between temperament/character dimensions and family environments.
