Objectives To identify whether Sovereign-Minister-Assistant-Courier (君臣佐使) Theory and Meridian Tropism (歸經) Theory of oral herbal medicine can be applied to trans-dermal medicine and whether pharmaceutical efficacy can be delivered to skin by Courier herb (使藥). Methods We reviewed previous studies related to Sovereign-Minister-Assistant-Courier Theory. And we examined whether prescription compositions based on Sovereign-Minister-Assistant-Courier Theory correspond with efficacy results of trans-dermal medicine experimentally identified. Results When Sovereign-Minister-Assistant-Courier Theory is applied to trans-dermal medicine, Courier herb act as delivering the effective components to the lesion penetrating skin barrier. And we identified that medicine absorbed through the digestive processes may not correspond with Courier herb applied topically. Conclusions We identified that Courier herb act as delivering the effective components to the lesion. But to strength evidences, additional studies on this action will be needed.

7H-dibenzo[c,g]carbazole(DBC)과 dibenz[a, j]acridine(DBA) 및 이의 대사물 trans-DBA-1,2-dihydrodiol(DBA-1,2-DHD), trans-DBA-3,4-dihydrodiol(DBA-3,4-DHD), trans-DBA-5,6-dihydrodiol(DBA-5,6-DHD)]에 의한 DNA adduct형성을 알기 위해 Hsd:ISR 생쥐 피부에 이를 투여하고 용매 추출법으로 DNA를 분리하고 $^{32}P$-postlabeling법으로 DNA adduct를 분석하였다. DBC를 피부에 투여하여 DNA adduct가 국소작용 부위인 피부와 내장기관인 간, 폐 및 신장에 형성되어 DBC는 국소 및 전신 발암작용이 있음을 알 수 있었다. 또한 DNA adduct활성도가 간에서는 높고 피부, 폐, 신장에서는 상대적으로 낮아 DBC에 의한 발암의 주 표적 장기는 간임을 추측할 수 있었다. DBA, DBA-3,4-DHD 및 DBA-5,6-DHD 투여에 의해 두개의 adduct가 피부에서 관찰되었다. 대사 물질인 DBA-5,6-DHD에 의해 2개의 adduct가 형성되었으나 그 양상이 DBA 및 DBA-3,4-DHD와는 달랐으며 DBA-1,2-DHD에 의해서는 DNA adduct 형성이 관찰되지 않았다. 이상의 결과로 DBA는 국소발암작용이 있으며 활성 대사물인 DBA-3,4-DHD가 최종 발암원(ultimate carcinogen)이고 DBA-1,2-DHD는 무독화 대사물질로 추측된다.

Background For patients with full thickness skin defects, autologous Split-thickness skin grafts (STSG) are generally regarded as the mainstay of treatment. However, skin grafts have some limitations, including undesirable outcomes resulting from scars, poor elasticity, and limitations in joint movement due to contractures. In this study, we present outcomes of Matriderm grafts used for various skin tissue defects whether it improves on these drawbacks. Methods From January 2010 to March 2012, a retrospective review of patients who had undergone autologous STSG with Matriderm was performed. We assessed graft survival to evaluate the effectiveness of Matriderm. We also evaluated skin quality using a Cutometer, Corneometer, Tewameter, or Mexameter, approximately 12 months after surgery. Results A total of 31 patients underwent STSG with Matriderm during the study period. The success rate of skin grafting was 96.7%. The elasticity value of the portion on which Matriderm was applied was 0.765 (range, 0.635-0.800), the value of the trans-epidermal water loss (TEWL) was 10.0 (range, 8.15-11.00)$g/hr/m^2$, and the humidification value was 24.0 (range, 15.5-30.0). The levels of erythema and melanin were 352.0 arbitrary unit (AU) (range, 299.25-402.75 AU) and 211.0 AU (range, 158.25-297.00 AU), respectively. When comparing the values of elasticity and TEWL of the skin treated with Matriderm to the values of the surrounding skin, there was no statistically significant difference between the groups. Conclusions The results of this study demonstrate that a dermal substitute (Matriderm) with STSG was adopted stably and with minimal complications. Furthermore, comparing Matriderm grafted skin to normal skin using Cutometer, Matriderm proved valuable in restoring skin elasticity and the skin barrier.
