Six different O/W cream bases containing 4% ascorbic acid dipalmitate and two different O/W cream bases containing 1% ascorbic acid were prepared. Percutanceous absorption of ascorbic acid as well as safety were determined using rabbits. The stability of the creams was also tested at room temperature. Ascorbic acid concentrations in urines varied depending on the characteristics of cream bases used. The absorption of ascorbic acid was increased and sustained with the cream bases containing branched chain esters of fatty acid instead of natural oils used currently. The excretion level of ascorbic acid in urine was high with the cream base including nonionic surfactants and a small quantity of natural oils. The creams containing nonionic surfactants showed excellent stability, while those containing anionic surfactants were not stable in terms of pH, odor and coloring test at room temperature during six months. But, the two creams containing ascorbic acid were unstable. All the cream bases tested showed good safety.

GM-CSF is a multipotent growth factor, which also plays an important role during the process of wound healing. rrhGM-CSF was specifically produced from rice cell culture in our laboratory (Hanson Biotech Co., Ltd, Daejeon). The rrhGMCSF contains more oligosaccharide side chains than any other types of GM-CSF. This work was taken to evaluate the influence on wound healing of rrhGM-CSF in male golden hamsters. Full thickness skin defects of 9 mm in diameter were made in the back of hamsters, and 100 ${\mu}L$ ointment containing rrhGM-CSF 50 ${\mu}g/mL$ was applied. Control groups were given ointment without rrhGM-CSF. The wound sizes were relatively reduced and skin was well regenerated in the experimental group compared with the control group. Structurally, reepithelialization and architecture of the skin following injury were well accomplished in the experimental group. And also, positive reaction of PCNA of the skin following injury was more prominent in rrhGM-CSF containing ointment treatment group. Since this type of GM-CSF has highly glycosylated side chains, the effectiveness might be retain longer and stable, regarding acceleration of wound healing in the animal model. The present study has important implications for further development of the therapeutic manipulation of wound healing using rrhGM-CSF.

Objectives : The present study was conducted to determine whether Jerksukji-san and Tangnisodok-eum have an effect on treatment of burn. Methods : 24 male rats were randomly divided into 4 groups. Burns were created by scalding on the skin surface. Immediately after being burned, the rats of group 1 were applied with silver sulfadiazine ointment topically on the burn wound. The rats of group 2 were applied with Jerksukji-san ointment topically and administrated Tangnisodok-eum orally. The rats of group 3 were applied with Jerksukji-san ointment topically. The rats of group 4 were cleaned with saline solution. All treatments were applied twice a day. After 3 and 7 days the inflammatory cellularinfiltration and epidermal gap were measured. Data were analyzed by one-way ANOVA and Kruskal-Wallis test. Results : The rats of groups 1 and 2 showed a statistically narrow epithelial gap compared with those of groups 3 and 4 on the third and on seventh days (p<0.05). Group 3 showed a statistically narrow epithelial gap compared with group 4 on the third and seventh days (p<0.05). The decrease of inflammatory cellularinfiltration observed in group 2 was bigger than in the other groups (group 2>1>3>4) on the third and seventh days. Conclusions : These results demonstrate that Tangnisodok-eum and Jerksukji-san ointment are effective to treat burn, and it is necessary for clinical study to better ascertain this method.

This clinical research was conducted to test patients with Atopic Dermatitis by external application with Hwangryeonhaedok-Tang in cosmetics. We gave scores to 31 patients who visited the Dept. of Oriental Medical Opthalmology & Otolaryngology & Dermatology of Semyung University Jecheon Oriental Medical Hospital from May 15th, 2008 to June 26th. Fifteen patients were treated with the ointment that contain Hwangryeonhaedok-Tang (experimental group) and sixteen patients were treated with normal ointment that doesn't have Hwangryeonhaedok-Tang (control group) for 4 weeks. We observed change of total IgE, eosinophil count, Skin Temperature, Transepidermal Water Loss(TEWL), Skin Hydration and Skin pH. Also Clinical Index of Atopic Dermatitis(SCORAD Index) and global assesment of efficacy were used to evaluate the effects of Hwangryeonhaedok-Tang. Statistical analysis was performed by using frequency analysis and descriptive analysis. Statistical significance was achieved if the probability was less than 5%(p<0.05). After 4 weeks of external application treatment, SCORAD Index in experimental group was significant statistically decreased compared with control group. After 4 weeks of external application treatment, total IgE of both groups were decreased and eosinophil count in control group was decreased but experimental group was unstatistically decreased. Unstatistically, both groups didn't showed significant effect on Skin Temperature. Transepidermal Water Loss(TEWL) in both groups were increased but experimental group was significant decreased compared with control group. Skin Hydration in experimental group was significant statistically increased compared with control group. Statistically, both groups didn't showed significant effect on Skin pH. Only experimental group showed little increase. After 4 weeks of external application treatment, experimental group showed significant effect on global assesment of efficacy. Considering the above results, we can speculate that cosmetics with Hwangryeonhaedok-Tang has some therapeutical effects in mitigating the symptoms of Atopic Dermatitis.

Background This study aimed to assess the effects of the topical application of tamoxifen on wound healing of burned skin in Wistar rats by evaluating 3 healing characteristics: fibrotic tissue thickness (FTT), scar surface area (SSA), and angiogenesis in the healed scar tissue. Methods Eighteen male Wistar rats were used in this study. A third-degree burn wound was made on the shaved animals' back, measuring $2{\times}2{\times}2cm$. In the first group, a 2% tamoxifen ointment was applied to the wound twice daily for 8 weeks. The second group received a placebo ointment during the same period. The third group did not receive any treatment and served as the control group. Results The median (interquartile range=[Q1, Q3]) FTT was 1.35 (1.15, 1.62) mm, 1.00 (0.95, 1.02) mm, and 1.25 (0.8, 1.5) mm in the control, tamoxifen, and placebo groups, respectively (P=0.069). However, the FTT in the tamoxifen group was less than in the placebo and control groups. The median angiogenesis was 3.5 (3.00, 6.25), 8.00 (6.75, 9.25), and 7.00 (5.50, 8.25) vessels per high-power field for the control, tamoxifen, and placebo groups, respectively (P=0.067). However, the median angiogenesis was higher in the tamoxifen group than in the control group. No significant difference was observed in the mean SSA between the tamoxifen group and the control group (P=0.990). Conclusions Local application of tamoxifen increased angiogenesis and decreased the FTT, with no change in the SSA in burned skin areas. These effects are expected to expedite the wound healing process, reducing contracture and preventing hypertrophic scar and keloid formation.

This study was conducted with 60 adult males who visited the Atomi Cooperative Clinic(Atomi Dermatology/Pediatrics/Oriental Clinic) in Seoul between May 2003 and December 2004; they were divided into three groups, each of which consisted of 20 persons, according to the level of erythma and then each group was subdivided to consist of ten according to whether they received skin treatment and care. The standard care provided to two groups involved topical steroids and oriental medicines prescribed by a dermatologist and a oriental doctor, respectively. 5th-grade topical steroid ointment was applied to the face and 3rd-grade to the limbs; a oriental medicine was administered in a lukewarm state half an hour after meals three times a day. To determine how special and systematic skin treatment and care was helpful in treating atopy, a skin treatment system was applied to the experimental group while the control group was provided with standard care alone. By using Mexameter(MX18) manufactured by ck-mpa as a measuring tool, the inflammation level was observed at the right antecubital space during each visit to the clinic. In view of the re suits, introduction of the systemic skin care for A. D to legitimate treatment provided by a medical institution is expected to be an appropriate supplementary treatment for adult patients who suffer from frequent recurrence of atopic dermatitis.

An 87-year-old woman was referred for the extraction of residual teeth and removal of tori prior to prosthetic treatment. After surgery under general anesthesia, the surgical tape was removed to detach the bispectral index sensor and the hair cover. After the surgical tape was removed, skin injury occurred on the left side of her face. After epidermis repositioning and ointment application, a dressing was placed over the injury. Her wound was found to have healed completely on follow-up examination. Medical adhesive related skin injury (MARSI) is a complication that can occur after surgery and subjects at the extremes of age with fragile skin are at a higher risk for such injuries. Careful assessment of the risk factors associated with MARSI is an absolute necessity.
