Background and Objective : Atrophic scars are the most common complication of acne. Many modalities are proposed but each does not yield satisfactory clinical outcomes. Among therapeutic modalities of acne scars, subcision is a simple, safe procedure with a different and basic mechanism for correcting atrophic and depressed scars. However, there are few reports about such procedure. This study performed to evaluate the effect of subcision treatment on atrophic acne scar. Methods : Five patients with atrophic acne scars of various types(rolling, superficial and deep boxcar, pitted and icepick) were treated by superficial dermal undermining with 25~27 gauge needles. We used GASC(Global Acne Scarring Classification). Satisfaction degree was asked from the patients. Results and Conclusions : After observing patients satisfaction, comparing case photos and GASC, it can be considered that subcision treatment brings great results when performed on atrophic post acne scars.

In forensic genetics, when it is not possible to confirm an individual's identity through STR profile analysis, additional information about the individual can be obtained using DNA-based phenotypic traits estimation. Recently, various researches have been conducted on methods to determine externally visible characteristics (EVC) such as eyes, hair, and skin color. However, relying solely on such phenotypic traits information has limitations for application in East Asian regions, including Korea. In this study, in order to utilize EVC related to an individual's appearance as investigative information, SNPs related to eye shape, hair thickness, skin color, as well as baldness, body type, high myopia, facial shape, acne, and behavioral habits were explored. A total of 50 SNPs were selected, and a targeted amplicon NGS panel capable of amplifying them all at once was developed. Experimental results confirmed the allelic types and frequencies of the 50 SNPs in 14 samples. We plan to use this panel to investigate the correlation between genotype and phenotype using various samples, and to develop methods for interpreting the results.

The in vitro antibacterial activities of honeybee(Apis mellifera. L) venom collected by a bee venom collector were investigated against several bacteria including antibiotic-susceptible and resistant Propionibacterium acnes. Honeybee venom was prepared with different concentrations and they showed strong antibacterial activites. Honeybee venom inhibited the growth of the tested antibiotic-resistant P. acnes at the concentration of 1 mg/ml. The inhibitory activities of the honeybee venom showed time-dependent manner. Honeybee venom did not influence the viability of human dermal fibroblast at the high concentration of less than 10 mg/ml. From these results, we expect that honeybee venom has strong antibacterial activities and has advantage for treating cure.

Lemon and eucalyptus oils were known to have various biological effects such as anti-aging and sterilizing action. However these essential oils were not well studied about their antioxidant activity and antimicrobial activity against specific skin flora. In this study, we investigated antioxidant activity and antimicrobial activity of lemon and eucalyptus oils by using DPPH radical scavening activity and paper disc method. Lemon oil showed the high DPPH scavenging activity, while eucalyptus oil did not. Blending oils of lemon and eucalyptus had little enhancememt onantioxidant activity. Paper disc method demonstrated that each oil had a high antimicrobial effect against C. albicans and P. acnes in a concentration dependent manner. The blending oils had enhancememt on antimicrobial effect against P. acnes. In conclusion, the blending oil of lemon and eucalyptus can be used as a more effective natural agents for cure of skin trouble and acne.

Leuconostoc mesenteroides CJNU 0705 was isolated from a breast milk sample and identified by 16S rRNA gene sequencing and confirmed by its ability to produce dextran from tryptic soy agar plates supplemented with 2% sucrose. This strain can absorb various heavy metals including lead (Pb) and cadmium (Cd) which are both found in fine dust and have been shown to be harmful to human skin. In addition, Leu. mesenteroides CJNU 0705 has demonstrated antimicrobial activity against Propionibacterium acnes, the primary causative agent of acne. Given these traits it was natural to evaluate the use of this strain in the fermentation of several natural extracts from green tea, carrot, annual wormwood, parsley, broccoli, and corn silk, which are known to improve skin health, to see if it could increase their dextran content when supplemented with no sucrose, 2% sucrose, or 2% sucrose and 3% yeast extract. The extracts supplemented with both yeast and sucrose were found to produce the most dextran, which was confirmed by the scanning electron microscope (SEM) images. These results suggest that Leu. mesenteroides CJNU 0705 and its fermented natural extracts could be used as functional materials for improving human skin health.

The authors surveyed the inhabitants of a rural area to assess the patterns of medical utilization on dermatoses. Seven hundred and sixty new outpatients of dermatoses were examined and surveyed with formed questionnaire from March 1997 to February 1999. The results are as follows; 1. Among 760 new outpatients, the number of male patients was 283(37.2%) and that of female patients was 477(67.3%). 2. The most common dermatoses was Tinea pedis(34.9%), and follows senile pruritus, contact dermatitis, housewife eczema, seborrheic dermatitis, numular dermatitis, atopic dermatitis, Tinea corporis, Tinea ungium, acne vulgaris, impetigo, keratolysis exfoliativa, chronic urticaria, Tinea cruris and Molluscum contagiosum in orders. 3. Drug store was the most frequent places where patients initially visited for their skin diseases(39.6%) and followed by non dermatologic clinic, dermatologic clinic and general hospital in orders. 4. One hundred and twenty one(15.9%) patients have been experienced folk treatment. It was founded that the topical vinegar application or soaking was the most common method. Many patients felt no symptom improvement after the folk treatment(48.8%). Seventeen point four percent of patient felt symptom worsened. The results of this study suggest that many of the rural inhabitants are lack of understanding on their dermatoses. So many physician who are in charge of the primary care in rural area have to pay attention to the common dermatoses and educate patients on their medical utilization.

In an epidemiological study of metal workers exposed to metalworking fluids (MWF), the prevalence time of Evolution, seasonal occurrence and clinical type of contact dermatitis were investigated. Compostional analysis of MWF with HPLC, dermatological examination and two consecutive questionnaire surveys were conducted. Study population was divided into two groups ; workers contact to cutting oil and workers contact to rust preventive oil. In the analysis of MWF, aliphatic hydrocarbons, having 12-20 carbons, was most common composition(49.04%) of cutting oil otherwise, major contents (90.99%) of the rust preventives oil were aliphatic hydrocarbons composed of 6-9 carbons. The frequency (point prevalence) of contact dermatitis(CD) was 7(12.7 per 100 subjects) in the dermatological examination of 55 workers. As the result of second survey for contact dermatitis, cumulative prevalence of oil working full-time and recent 1 year prevalence in two groups were 28.0, 16.7 and 15.1, 12.5 per 100 subjects. There were no difference in the prevalence of CD by oil, age, oil contact duration. Summer is the most common evolution season in workers exposed to cutting oil, but not in workers exposed to rust preventive oil. Major clinical type of CD was erythematous papules in both groups. It presents the importance of preventive measures that 51.1% suffer from contact dermatitis had medical care at their own expense, and 47.1% of them felt serious about their contact dermatitis. From the fact that 68.6% think cotton gloves protective apparatus, we emphasize the need for health education.
