Όλ¬Έ(λ°μ¬)--μμΈλνκ΅ λνμ :μκ³Όλν μνκ³Ό,2020. 2. κΆμ€μ.Shikimic acid (SA) has recently been found to be a major component of plant stem cells. The exact effects of SA on human hair follicles (HFs) is unknown. The purpose of this study was to examine the effects of SA on hair growth. We investigated the effect of SA on an in vivo C57BL/6 mouse model. We examined the expression of mannose receptor (MR), which is a known receptor of SA, in human HFs and the effect of SA on human dermal papilla cells (hDPCs), outer root sheath cells (hORSCs), and on ex vivo human hair organ culture. SA significantly prolonged anagen hair growth in the in vivo mouse model. We confirmed expression of the MR in human HFs, and that SA increased the proliferation of hDPCs and hORSCs. It was found that SA enhanced hair shaft elongation in an ex vivo human hair organ culture. SA treatment of hDPCs led to increased c-myc, hepatocyte growth factor, keratinocyte growth factor and vascular endothelial growth factor levels and upregulation of p38 MAPK and cAMP response element-binding protein levels. Our results show that SA promotes hair growth and may serve as a new therapeutic agent in the treatment of alopecia.μν΄μ°(Shikimic acid)μ μλ¬ΌμΆμΆλ¬Όμ μ±λΆμΌλ‘μ, νμ°ν, νμΌμ¦ ν¨κ³Όκ° μλ €μ Έ μκ³ , νλ°μ΄λ¬μ€μ (Oseltamivir)μ μλ£λ‘ μ°μ΄λ©΄μ μ£Όλͺ©μ λ°κ² λμλ€. νΉν μν΄μ°μ μ΅κ·Όμ μλ¬Όμ μ€κΈ°μΈν¬ μΆμΆλ¬Ό μ±λΆμΌλ‘ μλ €μ Έ, μ΄λ₯Ό μ΄μ©νμ¬ μ±μ²΄μ λΆνλ μΈν¬λ₯Ό λ§μΆ€ν λ§λ₯μ€κΈ°μΈν¬λ₯Ό μ λνλ λ°©λ²μ΄ νΉνλ‘ λ±λ‘λ λ° μλ€. λ°λΌμ μ΄λ¬ν νΉμ±μ΄ λͺ¨λμ μ¬μλ₯λ ₯μ μν₯μ μ€ μ μμ κ²μ΄λΌ μκ°λλ μμ§κΉμ§ λ°λͺ¨ν¨κ³Όμ λν λΆλΆμ μ μλ €μ Έ μμ§ μλ€. λ°λΌμ μ΄ μ°κ΅¬λ μΈμ²΄λͺ¨λμ μ‘°μ§λ°°μ쑰건μμ μν΄μ°μ λͺ¨λ° μ±μ₯ ν¨κ³Όλ₯Ό λ°νκ³ , κΈ°μ μ κ·λͺ

A STUDY ON THE SURFACE ROUGHNESS OF GLAZED PORCELAIN AND POLISHED PORCELAIN
Porcelain is considered to be one of the materials of choice for restoration where esthetics is of concern. But porcelain surface without final glazing treatment may induce undesirable results such as inflammatory response on adjacent soft tissues due to plaque accumulation and increased wear of opposing teeth. Therefore, rough porcelain surface must be smoothened by final glazing treatment or chairside polishing procedure. The purpose of this study was to compare the surface roughness among self-glazed, overglazed and polished porcelain with various polishing kit, and to detect which phase of polishing is optimal in clinic. Specimens were fabricated with Vita VMK porcelain. The surface treatment of each group was performed as follows. Group 1 : overglazing treatment Group 2 : self-glazing treatment Group 3 : polishing with the Truluster Polishing System for Porcelain(Brasseler, U.S.A.) Group 4 : polishing with the Exa Cerapol Adjustment kit (Edenta dental products, Switzerland) followed by finishing with diamond-filled polishing paste Group 5 : polishing with the Shofu Porcelain Adjustment kit (Shofu inc., Japan) followed by finishing with diamond-filled polishing paste. At each polishing steps, the measurement of Ra and Rq values were performed, and the surface was examined by scanning electron microscope. The results were as follows : 1. Overglazing treatment brought smoother surface than self-glazing treatment. 2. Polishing systems without porcelain polishing paste did not make better result than self-glazing treatment. 3. Polishing system with porcelain polishing paste made similar result to overglazing treatment. 4. Applying diamond-filled polishing paste after using polishing system which has no porcelain polishing paste produced surface as smooth as overglazing treatment does
