  • Toona sinensis (TS) leaf is known to antinociceptive, antioxidative stress and skin moisturizing effects. Acnes vulgaris is a chronic skin disease with various symptoms including itchiness, pain and interruption of normal skin function. Propionibacterium acnes (P. acnes) is a major factor in the occurrence of inflammatory acnes. This study evaluated the antioxidant and anti-inflammation effects by TS extract from adventitious shoots. TS extract showed anti-inflammatory activities by suppression of pro-inflammation mediators (iNOS and COX-2) in LPS-stimulated RAW264.7 cells. TS extract also has anti-inflammatory activities by inhibiting the secretion of pro-inflammatory cytokines on P. acnes-stimulated HaCaT cells. These effects were regulated by MAPK signaling pathway. Therefore, we suggest that TS extract from adventitious shoots might have applications as a medicine for treating P. acnes-induced skin diseases.

  • Gardeniae Fructus is consisted of geniposide and it's derivatives. For the purpose of treatment of skin disease, geniposide and hydrolyzed products (HP) of Gardeniae Fructus were studied on skin permeation and cross1inking with biological tissue. The hydrolyzed products (HP) and active ingredients of Gardeniae Fructus were identified and investigated about skin permeability. Genipin has provided low cytotoxic cross1inking reagents and formed stable and biocompatible crosslinked products. The permeation enhancing effects of geniposide and genipin under the hydrolyzed products of cream and hydrogel preparations were tested using Franz type diffusion cell and the skin of hairless mouse. The remaining proportions of geniposide and genipin were measured in the hydrolyzed products of cream and hydrogel preparations. The crosslinking of epidermic and endodermic tissue with genipin under the hydrolyzed prodcuts of cream and hydrogel preparation was observed using light microscopy. Increased absorption ratio of the skin of hairless mouse about genipin was higher than that of geniposide. Loads at break, tensile strengths and skin permeation rate of the hydrolyzed products (HP) of cream and hydrogel preparations were higher than the nonhydrolyzed products (NHP). The hydrolyzed products (HP) of cream and hydrogel of Gardeniae Fructus Extracts were proper preparations and crosslinking agents to increase the transdermal absorption with epidermic and endodermic tissue.

  • Objective : Acne is very common disease, it can leave permanent scars. However, there are few reports about it in oriental medicine academia. This study performed to evaluate the effect of reconstruction of skin scars and auto microneedle therapy system on acne scars. Methods : Six patients were treated by using reconstruction of skin scars and auto microneedle therapy system. We compared the degree of treatment of acne scars on pre and post case photos and Qualitative Global Acne Scarring Grading System(QGASC). Satisfaction degree were asked from the patients. Results & Conclusion : After comparing case photos and QGASC, observing patients satisfaction, it can be considered that reconstruction of skin scars and auto microneedle therapy system to be valid acne scars treatment.

  • UV-irradiated skin shows acutely erythema, edema, pigmantation (sunbum) and chronically coarse wrinkling, roughness, dryness, laxity (photoaging). Jawoongo(紫雲膏, JW) is clinically useful external application and effective bum, sunburn, wound and symptom of dryness(燥症) in skin disease. In this experiment, we examined if JW could cure the UVB-mediated acute skin damages, inhibit UVB-mediated oxidative stress and inflammation of skin, and block the photoaging. In vivo test, we found that JW could effectively cure the UVB-mediated acute skin damages(erythema, edema, angiogenesis, hyperplasia, infiltration of lymphocytes) and inhibit expression of HSP70, CYP1A1 and p53. We also found that JW could repair destruction of collagen fiber and inhibit activation of MMP-9, and inhibit expression of $NF-{\kappa}B$ p65, iNOS, hyperplasia of keratynocyte. In vitro test, we found that JW could inhibit expression of IKK, iNOS mRNA, and production of NO. These findings shows that JW could cure the UVB-mediated acute skin damages, inhibit UVB-mediated oxidative stress and inflammation of skin, and block photoaging.

  • Toxic shock syndrome(TSS) is a multisystemic disease presenting with high fever, sunburn like rash that subsequently desquamates, and hypotension mainly caused by toxin producing strains of Staphylococcus aureus. It was first reported in 1978 by Todd et al, thereafter many patients have been reported. In children, TSS is rare and must be differentiated from other erythematous febrile diseases such as Kawasaki disease, scarlet fever, drug eruption etc. We experienced a case of TSS associated with staphylococcal cellulitis in 26-month old boy, who was presenting similar symptoms to Kawasaki disease at initial stage of illness. As time passed, the patient represented more typical symptoms of TSS and Staphylococcus aureus was isolated from cellulitis of the right elbow area. Therefore, we report this case with a brief review of related literatures.
