  • The aim of this work was to develop and evaluate solid lipid nanoparticles (SLN) containing all-trans-retinoic acid (ATRA) for topical delivery. SLN composed of coconut oil and curdlan improved the suspension instability of ATRA in aqueous solution. The photodegradation of ATRA by light was reduced by incorporation in SLN. The loading efficiency of ATRA in SLN was higher than 95% (w/w). The amounts of ATRA released from SLN at $4^{\circ}C$ and at $37^{\circ}C$ were less than 15% and more than 60% (w/w) for 96 h, respectively. The ATRA-loaded SLN can be used as a potential carrier for topical delivery.

  • 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 and Aim : Health care and cosmetics as well as quality of life is now a matter of concern and many categories of complementary and alternative medicine fall into the territory of the medical practice of Korean medicine. Accordingly, penalties are being taken for unlicensed medical practices of Korean medicine in so called complementary and alternative medicine area. There is a possibility of violating the law for the public part because it is not clearly stipulated in the law as to what is a licensed medical practice. Materials and Method : The significance of the Medical Service Act and the Act on Special Measures for the Control of Public Health Crimes were reviewed, and the related supreme court cases were discussed upon the legal aspect of processing the unlicensed medical practice of Korean medicine. The legal information was provided from the National Law Information Center of the Ministry of Government Legislation, and the information websites of the Supreme Court and the Constitutional Court. Results : The concept of medical practice, which is essential in judging the case of unlicensed medical practice, is 'prevention and treatment of diseases through diagnosis, examination, prescribing, medication, or surgical procedures based on medical expertise', and the 'acts that may result in harm and injury of health unless performed by a medical person'. With respect to the medical practice of Korean medicine, the concept includes 'prevention and treatment of diseases using the principle of traditional Korean Medicine'. Conclusions : The concept of medical practice should be clearly stipulated in the law for the control over the unlicensed medical practices of Korean medicine. And it is important to move from the current concept of medical person-oriented medical practice emerging from the national system of healthcare control, to a concept that can accept the era of health managing-oriented medical environment and the co-governance of the healthcare providers and consumers for the future.
