Objectives The present study examined the recent domestic and international trends of non-surgical treatment of lumbar spinal stenosis (LSS). Methods The studies on non-surgical treatment of LSS were investigated via searching Korean web databases and PubMed. As a result, 39 studies were analyzed according to the authors, the types of study, the relationship to surgical treatment and the method of treatment. Results The first authors’ occupations were identified as 17 doctors, 12 Korean medicine doctors, six physiotherapists, three chiropractic doctors and one doctor of science. The most common type of study in Korea was the case report and most of the studies were retrospective. Overseas, there were many prospective or experimental studies including randomized controlled trials (RCT). In Korea, non-surgical treatment was performed independently of surgical treatment in most cases. Among non-surgical treatments, the most researched treatment was traditional Korean medicine (TKM), followed by injection therapy, exercise therapy, and physical therapy. Conclusions Through this review, we can determine the effectiveness of TKM and its research direction. TKM should be studied experimentally including RCT and it should be conducted not only on acupuncture, but also on other treatment methods such as acupotomy, chuna, and herbal medicine. It is also necessary to conduct studies on TKM before and after surgery to compare the effects of surgery and TKM together, as well the effects on non-surgical treatments.

대추 아임계수 추출물의 폴리페놀 함량 및 산화방지 평가
고민정(Min-Jung Ko),권미리(Mi-Ri Kwon),정명수(Myong-Soo Chung) 한국식품과학회 2021 한국식품과학회지 Vol.53 No.3
아임계수 추출 기술을 이용하여 대추 추출물을 얻고 총 페놀 함량, DPPH 라디칼 소거능과 ABTS 라디칼 소거능을 이용하여 추출조건에 따른 페놀 성분 함량 변화 및 산화 방지효과를 확인하였다. 아임계수 추출물은 총 페놀 함량, DPPH라디칼 소거능, ABTS 라디칼 소거능의 결과 값이 모두 메탄올 및 에탄올을 이용하여 추출한 결과 보다 우수하게 나타났다. 아임계수 추출법은 메탄올 및 에탄올을 이용하여 추출하는 방법 보다 추출 시간도 20분 이내로 짧았고, 유기용매를 사용하지 않고 친환경적으로 추출할 수 있었다. 아임계수 추출물의 총 페놀 함량과 산화방지 효과의 결과는 높은 상관관계를 보였는데, 항산화 효과가 있는 페놀류가 많이 추출될수록 산화방지 효과도 우수하게 나타났다. 본 연구를 통해, 아임계수 추출 방법은 오직 물을 사용하여 유효성분을 추출하는 친환경적이고 안전한 신가공기술이며 잠재성과 우수성을 확인하였다. 아임계수 추출기술은 앞으로도 다양한 유효성분추출 및 소재 가공으로 식품 산업에 응용하여 사용될 수 있을 것이다. Subcritical water extraction (SWE) is an eco-friendly extraction method that uses only purified water as a solvent under high temperature and high pressure conditions. In this study, total phenolics, and antioxidant activity were evaluated in Ziziphus jujuba Mill extracts from subcritical water obtained by varying the extraction temperature (110-190℃) and extraction time (1-20 min). Total phenolics was maximized with extraction at 190℃ for 15 min (67.79±3.45 mg gallic acid equivalent/g jujube). The 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity (48.84±4.74%) and 2,2-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) free radical scavenging activity (84.75±1.15%) were maximal at extraction conditions of 190℃, for 20 min. All jujube extracts prepared using SWE had higher total phenolics and antioxidant activities than extracts prepared using organic solvent extraction (60℃, 120 min), including methanol and ethanol. SWE could be an excellent alternative to organic solvents for extracting phenolics and antioxidant compounds.
