  • The aim of this study was to evaluate if a composition of herb extracts, PLX-PLS was effective to treat atopic dermatitis (AD) in mice. SPZZC is a composition of herb extracts containing the roots of Scopolia parviflora and Paeonia lactiflora, the herb of Zizania caudiflora, the fruit of Ziziphus jujuba and the leaf of Chinese arborvitae. AD in BALB/c mouse was induced by patching ovoalbumin on the backside, while it in NC/Nga mouse was induced by repeated application of 1-chloro 2,4-dinitrobenzene (DNCB). Mice were topically treated with SPZZC or Domohorn ointment on the backside for 2 weeks (BALB/c) or 1 week (NC/Nga). Scratching behavior, clinical skin severity and the levels of WBC, neutrophil, eosinophil and total serum IgE were measured. After AD induction, scores of scratching behavior and clinical skin severity and the levels of WBC, neutrophil, eosinophil and total serum IgE were increased. Treatment with SPZZC significantly decreased scores of scratching behavior and clinical skin severity in a dose dependent manner in NC/Nga and BALB/c mice. Treatment with SPZZC 2% significantly decreased also the levels of WBC, neutrophil, eosinophil and total serum IgE. Especially, treatment of SPZZC 2% reduced more rapidly score of clinical skin severity than clobetasol cream. These results suggest that the SPZZC may be an alternative substance for the management of AD.

  • Objectives : The aim of this study is to report the effect of Capsosiphon fulvescens(Maesangi) extract(MSE) on contact dermatitis(CD). Methods : CD induced by Dermatophagoides farinae body(Dfb) in NC/Nga mice. 4% sodium dodecyl sulfate(SDS) $150{\mu}l$ and Dfb(10mg/ml) ointment 100mg were topically treated twice a week for four weeks. MSE 200 mg/kg was topically treated every 4weeks. Every week, we examined the skin lesions, weight of spleen and lymph node, epidermal thickness, production of Tumor necrosis factor-alpha($TNF-{\alpha}$) and interleukin-6(IL-6). Results : MSE reduced features of Dfb-induced skin lesions, weight of spleen and production of $TNF-{\alpha}$. MSE significantly reduced weight of lymph node, epidermal thickness, number of mast cells and production of IL-6. Conclusions : MSE may have a potential therapeutic effects for CD by suppressing allergic inflammation.

  • Metronidazole (MD), which is used as an antibiotic, is largely used as an oral and skin application agent, and has inhibiting effect on the production of the fungus causing malodor. However, the maximum drug inclusion concentration is 0.75% of skin ointment in commercially available. In this study, hydrogels containing high concentration of metronidazole were prepared by using radiation crosslinking technique based on biocompatible polymers, and release characteristics and antimicrobial properties were evaluated. This study was preliminary carried out to investigate whether it could be used effectively as antibacterial dressing materials.

  • Titrated extract of Centella asiatica (TECA) contains three principal ingredients, asiaticoside (AS), asiatic acid (AA), and madecassic acid (MA). These components are known to be clinically effective on systemic scleroderma, abnormal scar formation, and keloids. However, one problem associated with administration of TECA is its low solubility in aqueous as well as oil medium. In this study, various nonionic surfactants and bile salts as anionic surfactant were tested and screened for solubilizing TECA with a view to developing topical hydrogel type of ointment which is stable physicochemically, and has better pharmacological effects. When TECA was incorporated into various nonionic surfactant systems, labrasol had the most potent capacity for solubilizing TECA. In cases of bile salt systems, Na-deoxycholate (Na-DOC) had foremost solubilizing capacity, even more than labrasol. In differential scanning calorimetric study, the peaks of AA, MA, AS and Na-DOC disappeared at the coprecipitate of $1\%$ TECA and $1\%$ Na-DOC, suggesting the optimum condition of Na-DOC for solubilizing TECA. When the physicochemical stability of hydrogel containing this mixture was assessed, it was stable at room temperature for at least one month. Pharmacologically it significantly decreased the size of wound area at the $9^{th}$ day when applied to the wound area of rat dorsal skin. Taken together, solubility of TECA was dramatically improved by using non ionic and anionic surfactant systems, and Na-DOC was found to be the most effective solubilizer of TECA in formulating a TECA-containing hydrogel typed ointment. Moreover this gel was considered to be applicable to clinical use for wound healing effect.

  • Objectives : The purpose of this study is to report on the treatment of wound dressing in patients with diabetic foot ulcers in the dermatology clinic of Korean medicine. Methods : First, sufficient marginal resection of the ulcer and necrotic tissue on the foot of a patient with diabetic peripheral neuropathy was performed. Inflammation was treated with Anti-inflammatory pharmacopuncture solution, and dressings were applied for one month using Cornu Cervi Parvum pharmacopuncture solution, and Haeboo ointment for granulation tissue formation and skin regeneration. Results : After 10 days of the treatment, the formation of new granulation tissue was observed in the necrotic tissue area, and the extent of the lesion decreased sharply from the 14th day. On the 40th day, epithelialization progressed so that the treatment was terminated, and complete keratinization of the site was observed at follow-up 3 weeks after the end of the treatment. Conclusions : In the treatment of wound dressings in diabetic foot ulcer patients, marginal resection treatment with the application of pharmacopuncture solution and herbal ointment showed good effect.

  • The objective of this investigation was to develop nanostructured lipid carriers (NLCs) of tacrolimus by the hot homogenization technique by sonication. NLCs are commonly prepared by emulsification and lyophilization. The feasibility of fabricating tacrolimus-loaded NLCs was successfully demonstrated in this study. The developed NLCs were characterized in terms of their particle size, zeta potential, entrapment efficiency (EE) of tacrolimus, and morphology. Studies were conducted to evaluate the effectiveness of the NLCs in improving the penetration rate through hairless mouse skin. Tacrolimus-loaded NLCs were found to have an average size of $123.4{\pm}0.3\;nm$, a zeta potential of $-24.3{\pm}6.2\;mV$, and an EE of 50%. In vitro penetration tests revealed that the tacrolimus-loaded NLCs have a penetration rate that is 1.64 times that of the commercial tacrolimus ointment, Protopic$^{(R)}$.

  • Four N-adamantyl n-alkanamides were prepared by amide condensation reaction between amantadine and n-alkanoic acid. Their enhancing activity on the penetration of ibuprofen through rabbit skin from petrolatum ointment was evaluated in in-vivo experiment. The experiments showed that the compounds have a strong transdermal penetration-enhancing activity, and their activities were comparable with that of Azone. The measurements of the fluorescence polarization of DP[-i-labelled DPPC liposomes showed that these compounds considerablly decreased the phase transition temperature of the liposomes. The mechanism of the transdermal penetration-enhancing activity of the compounds was ascribed to the reduction of the resistance to drug flux of the stratum corneum lipid layers due to the loose packing of the layers when the bulk head group of the enhancers inserts into the layers.
