OBJECTIVE: The loudness dependence of the auditory evoked potential (LDAEP) has been known as an indicator of central serotonergic neurotransmission. Nicotine increases the release of serotonin levels. The current study investigated whether cigarette smoking would make difference in LDAEP among male patients with major depressive disorder. METHODS: Twenty-four non-smoking and 20 smoking male patients meeting DSM-IV criteria for major depressive disorder (MDD) were recruited. There was no significant difference in severity of MDD symptoms between the two groups. The age of participants ranged from 20 to 65 years old. Event-related potentials (ERP) N100 were measured on 5 different sounds (55, 65, 75, 85, 95 dB) and on 5 electrodes (Fz, Cz, Pz, C5, C6). The N1/P2 peak to peak amplitudes and amplitude slope according to 5 different sounds were calculated. RESULTS: LDAEP was significantly weaker in the smoking group in comparison to the non-smoking group (p<0.05). Among non-smoking group LDAEP was negatively correlated with a core depression subscale of Hamilton Rating Scale for Depression (HAM-D) (r=-0.41, p<0.05). CONCLUSION: LDAEP of the smoking patients with MDD group was weaker than the non-smoking patient with MDD group's. This result suggests that smoking may have increased the release of serotonergic neurotransmission in patients with MDD. Future studies need to examine LDAEP changes before and after tobacco use among smoking patients.

Kinship testing in forensic casework is largely based on a likelihood ratio (LR) approach with short tandem repeat (STR) markers; however, in order to efficiently identify potential relatives in a specific population, the threshold values for kinship prediction should be determined by analyzing the kinship index distributions of the population in question. In this study, 250,000 DNA profiles were simulated using allele frequencies at 20 autosomal STR loci in Koreans, then the LRs were calculated for true close relatives and unrelated pairs. The LR distributions in related and unrelated pairs under a given relationship were compared in 2 sets of 13 Combined DNA Index System (CODIS) and 20 STR profiles. Using 13 CODIS STRs, true relatives in parent/child and full-sibling relationships were sufficiently discriminated from unrelated pairs with LR thresholds of 1,000 and 100, respectively. However, the CODIS STRs lacked the discriminatory power to differentiate between related and unrelated pairs in uncle/nephew and first cousin relationships due to high false-positive and false-negative rates with a LR threshold of 10. Increasing the number of STR loci to 20 increased discrimination of close relatives, but high false results remained in uncle/nephew and first cousin relationships. The kinship index data from this study will help make decisions on various kinship testing and familial searching in Koreans.

BACKGROUND: Diet and weight concerns are commonplace and almost accepted features of life for girls during adolescence. Until recently, younger age groups haue largely been ignored, as these concerns were thought to be a product of pubertal development and sexual maturity. Girls under the age of fifteen therefore, have been assumed to be free of the pressures experienced by adult women. However, this belief is now hard to sustain. The object of the present study was to investigate the self-perception and body shape satisfaction in different weight categories of boys and girls aged 12-years old in Korea. METHODS: In May, 1995, one hundred and sixty seven boys and one hundred and twenty girls from two schools in Seoul completed assessments of body-esteem, self-esteem, body shape preference. The children's body weight and height were also measured. RESULTS: The heaviest children expressed the most discontent, having a low body-esteem, a desire for thinness. By the age of 12, girls boys already differ in their body shape satisfaction and differ in their body shape aspirations. There was a significant effect of weight category on the children's body esteem(boys(P =.005), girls(P=.0001). Children in both extreme categories, under-and over-weight, had lower body-esteem scores than those in other weight categories. However, it was the overweight children who had the lowest. reported body-esteem. Body esteem was highest among girls in the 'slightly underweight' category and highest among boys on the 'average weight' category. There was no effects of either weight category or gender on the childrens appraisal of self-esteem. A comparison of the points chosen on the silhouette scales to reflect current and preferred body shapes revealed clear gender differences. Of the girls, 63% placed their preferred body shape at a point thinner than their currently perceived shape, while only 15% chose a broader figure. In contrast,, 41% of the boys rated their preferred figure as broader than their current perception, and 37% as thinner than their current perception. CONCLUSIONS: This study has noted a relationship between body weight and self-perception in 12-year old children. The heaviest children expressed low body-esteem, a desire for thinness. This pattern was more characteristic of girls than boys. Even at this age, well before they have completed physical maturation, girls are aspiring to a body shape which is thinner than their average. This discontent experienced by the heaviest children on this sample was apparent in their lower body-esteem and the distance between their current and preferred body shapes. The girls preference was for thinness, while in the boys it was for a body shape which was broader than their current shape. From their responses, it would appear that the boys' desire was not for fatness, but for a more athletic and muscular build.

The estimation of age is an important issue in forensic science, and the forensic community has attempted many times to establish methods for solving this issue. Aging leads to alterations in tissues and organs at the molecular level. These alterations at the molecular level may aid forensic scientists to estimate the age of a living person or a dead body. Initially, the focus was on the genetic components of aging, but recently, epigenetic mechanisms have emerged as the key contributors to the alterations in genome structure and function that accompany aging. In particular, DNA methylation is one of the best-understood mechanisms, and it has been suggested as a promising biomarker for age estimation in many studies. In this review, we summarize the recent studies on age-associated DNA methylation changes in different tissues and discuss its possible and practical applications in forensics.

The purpose of this study was to evaluate the postoperative outcomes between the glaucoma triple procedure and the small incision cataract surgery using foldable silicone intraocular lens(IOL). This prospective randomized study comprised of 42 eyes which had the glaucoma triple procedure and 41 eyes which underwent small incision cataract surgery at chonnam University Hospital from May, 1994 to December, 1996. At least 3 months follow-up period was needed. Corrected visual acuity of 0.5 of better was obtained in 50% of triple procedure group and 88% of small incision cataract surgery group with the average lines of improved visual acuity of 5.6 and 7.2 respectively. There was no significant change in the refractive cylinder during the early postoperative period in both group. In the glaucoma triple procedure group, posterior capsular opacification(PCO) developed in significantly low incidence in the Mitomycin C using group and the incidence of PCO in eyes with IOL decentration was greater than in those without IOL decentration. In conclusion, patients who underwent glaucoma triple procedure using foldable silicone IOL showed excellent postoperative IOP control with success rate of 81%, rapid visual rehabilitation and refractive stability. We also found that glaucoma triple procedure with Mitomycin C was associated with lower incidence of PCO.

Tissue expansion in breast reconstruction is a invaluable alternative surgical procedure. the advent of permanent expander prosthesis eliminated a second operative procedure for removal of the expander and replacement with another permanent implant. When we consider the choice of method for breast reconstruction, we have to take account of the extent of mastectomy, past-medical history of the patient, timing of operation, and patient's motivation. It is still accepted that autogenous Breast reconstruction is the best choice of the mothed. As autogenous breast reconstruction increase in popularity, however, it requires longer operation time, more complicated technique, and careful attention to donor site. Autogenous breast reconstruction is also not good candidate for the patients who have diabetes, vascular disease, smoking, obesity, previous history of cesarean section, or further pregnancy planning. We have performed 10 immediate breast reconstructions after modified radical mastectomy using the permanent expander prosthesis, manufactured by Mentor corporation. Among these cases, 8 patients underwent cesarean section and 2 patients pregnancy. Although this method has advantages of simple technique, minimal morbidity, and low cost, it has some limitations for orientals. First, it is inevitable in superior fullness of the reconstructed breast because of round shape of the expander. Second, it is difficult to get ptotic breast because of thick and inelastic characteristics of oriental skin. Third, the ratio of expander base to projection is not appropriate for orientals because of their smaller chest size. We experienced 2 cases of spontaneous deflation for its manufactural defect itself. In our experience, we would like to suggest that new type of permanent expander prosthesis should be innovated.
