  • 배경: 매복지치의 수술적 발치 시 propofol과 remifentanil을 이용한 목표조절농도주입(Target controlled infusion) 의식하 정주진정법의 적절한 주입농도를 제시하고 그 안전성을 평가하고자 하였다. 방법: 매복지치의 수술적 발치가 예정된 미국마취학회 신체 등급 분류 1, 2에 속하는 15-65세, 142명(여 83명, 남 59명)의 환자를 대상으로 소급 연구하였다. 환자는 수술 전 목표조절농도주입법을 이용한 의식하 진정법 사용에 관한 동의서를 작성하였다. 정맥내 삽관을 시행하고 수액을 공급을 시작하고, 4-5 L/min의 산소를 비관을 통해서 공급하였다. Propofol과 remifentanil의 초기 목표 혈중농도는 각각 $0.5\;{\mu}g/ml$와 1.0 ng/ml로 정하였다. 수술 중, 환자의 불안 통증 정도에 따라 목표농도를 조절하였으며 최저 농도와 최대 농도, 평균 농도, 주입된 총 용량을 기록하였다. 또한 수축기혈압과 맥박 수, 산소포화도, 호기 말 이산화탄소량을 수술 시작 전, 수술 중 5분 간격으로 확인하고 기록하였다. 모든 측정치는 평균 $\pm$ 표준편차나 환자의 수, 초기 측정치에서의 백분율 편차로 표시하였다. 결과: 수술 동안의 목표 혈중농도의 평균은 propofol은 $0.54{\pm}0.11\;{\mu}g/ml$이고, remifentanil은 $1.11{\pm}0.30\;ng/ml$였다. 수술 중 조절된 최대농도는 propofol은 $0.6{\pm}0.23\;{\mu}g/ml$이고, remifentanil은 $1.3{\pm}0.63\;ng/ml$였다. 이는 의식하 진정에 해당되는 범의의 농도라고 할 수 있겠다. 진정동안 환자의 언어적 의사소통은 유지 되었으며 산소 포화도는 4-5 L/min 의 산소 보충 하에 98%이상으로 유지되었다. 수축기 혈압과 맥박은 대부분의 환자에서 정상변위범위(${\pm}20%$)내에서 유지되었다. 결론: 본 연구는 목표조절 농도주입 의식하 진정에서 사용된 농도(propofol $0.5\;{\mu}g/ml$, remifentanil 1.0 ng/ml)는 안전하게 의식하 진정을 가능한 것을 보여준다. 이는 치과 치료 시 목표조절농도 주입의식하 진정법에서 적절한 목표농도를 제시한다.

  • This study investigated a mixture of Astragalus membranaceus (AM) and Lithospermum erythrorhizon (LE) extracts (ALM16), exerts anti-inflammatory effects in lipopolysaccharide (LPS)-induced RAW264.7 macrophage cells, and its underlying mechanism. ALM16 was prepared by mixing AM and LE extracts in a ratio of 7:3 (w/w). Cytotoxicity of ALM16 in RAW264.7 cells was not shown up to 200 ㎍/mL of ALM16. The results of this study showed that ALM16 does-dependently inhibits the production of nitric oxide, prostaglandin E2 and pro-inflammatory cytokines (interleukin-1β, interleukin-6, and tumor necrosis factor-α) in LPS-induced RAW264.7 cells. ALM16 not only markedly reduced the protein expression levels of inducible nitric oxide synthase and cyclooxygenase-2 (COX-2) in LPS-stimulated RAW264.7 cells, but also inhibited the nuclear translocation and DNA-binding activity of nuclear factor-kappa B (NF-κB). In addition, ALM16 specifically inhibited the phosphorylation of c-Jun N-terminal kinase and extracellular signal-regulated kinases in LPS-stimulated RAW264.7 cells. In conclusion, these results suggest that ALM16 may exert anti-inflammatory effect by modulating mitogen-activated protein kinase and NF-κB signaling pathways.

  • Production of shikonin derivatives through cell suspension culture of Lithospermum erythrorhizon was investigated. Optimal concentrations of IAA and kinetin on the growth of cell suspension were 0.2 and 0.1 ppm respectively. Pigment content was markedly increased when aluminum oxide was added to the production medium and its optimal concentration was 1.5g/70ml medium. The most effective concentration of IAA was 0.5 ppm and the production of pigment did not depend on the kinetin concentration.

  • Fatty acid composition analysis was carried out from 60 species of Korean native medicinal plant to screen ${\gamma}-linolenic$ acid(GLA) resources. Oenothera odorata, SymPhytum officinal, and Lithospermum erythrorhizon contained ${\gamma}-linolenic$ acid with 9.5%, 3.5%, 7.2% of total fatty acid content, respectively. The vegetative organs usually contained higher level of ${\alpha}-linolenic$ acid than seeds. Some plants were found to be excellent source of unsaturated fatty acid.

  • The effect of low dose ${\gamma}$-radiation on the callus growth of Lithospermum erythrorhizon S. cultured on different medium and lighting condition was investigated. The 8 Gy irradiation stimulated callus growth on LS medium supplemented with BA 2 mg/L and NAA 2 mg/L, however, the growth of callus was more effective on LS medium supplemented with BA 1 mg/L and NAA 1 mg/L under 16 hrs day light. And on the LS medium containing IAA 0.2 mg/L, 16 Gy irradiation increased the callus growth by supplement with kinetin 2 mg/1 and the effect of kinetin was higher than BA at same concentration. The growth of callus was more vigorous on LS medium than MS medium in general. On M-9 medium, the growth of callus was poor regardless lighting conditions, however, by ${\gamma}$-ray irradiation of 16 Gy or 30 Gy, callus growth rates were increased by 30% or more than 30%, especially, under 16 hrs day light condition.

  • To produce ${\gamma}$-linolenic acid (GLA) by cell cultures of Lithospermum erythrorhizon, we optimized medium compositions including carbon sources, nitrogen sources and growth regulators. MS basal medium supplemented with 1.0 mg/L 2, 4-D was effective for callus induction from mesophyll tissue. Addition of sucrose at 88mM concentration induced active proliferation of suspension cells and increased GLA content. Increased supplement of potassium nitrate as nitrogen source resulted in proliferous cell growth and increased total fatty acid content Abscisic acid increased cell growth and fatty acid content in callus culture, whereas as it had an inhibitory effect in suspension cell culture.
