Human neutrophil elastase (HNE, EC 3,4,21, 11), a mediator of tissue breakdown, was inhibited by tetracycline, oxytetracycline and demeclocycline. Among them, oxytetracycline showed the most potent inhibitory effect on the activity of HNE. IC50 of this drug at our specific condition was less than 1 mM. Tetracycline inhibited human neutrophil elastase non-competitively, and oxytetracycline inhibited competitively. Ki values of tetracycline and oxytetracycline were 4.9 mM and 0.39 mM, respectively. Structural modified tetracycline, de-dimethylaminotetracycline, which showed no antibiotic activity since the active dimethylamino radical was removed from the position #4 of the tetracycline, showed similar inhibition effect on the activity of human neutrophil elastase to that of tetracycline. Thus, we speculated that inhibition of human neutrophil elastase by tetracyclines was not depended on the dimethylamino radical which is a critical active site for antibiotic effect, rather it was depended on the hydoxyl radical of tetracyclines. Therefore, the property of inhibiting elastase may be an additional molecular biochemical mechanism of action of these drugs at the inflammatory sites.

본 연구는 고학력 중년 여성을 대상으로 취업 여부에 따른 영양섭취 상태의 차이를 분석하여 고학력 중년 여성의 영양 및 건강관리를 위한 대책 마련의 기초자료로 활용하고자 시행되었다. 연구 대상자의 선정은 유의추출 방법으로 전업 여성은 고학력자 비율이 높은 대전시의 일정 지역에 거주하는 기혼여성으로 하였고, 취업여성은 여러 직업의 특성으로 인한 교란(confounding)을 줄이기 위하여 고학력 여성의 비율이 높은 기혼의 교사로 한정하였다. 연령에 의한 교란을 방지하기 위하여 연령대별로 동일 비율로 무작위 추출하여 전업여성 250명, 취업여성 236명을 대상으로, 24시간 회상법을 이용하여 조사 전일 하루동안의 식이 섭취 내용을 개별 면담으로 조사하였다. 1일 영양소 섭취 조사 결과 취업여성은 전업여성에 비해 인, 비타민 B$_1$, B$_2$를, 전업여성은 취업여성에 비해 지방 및 동물성 지방, 나트륨, 비타민 C, 엽산을 많이 섭취하고 있었다. P/M/S비는 전업여성 1/1.19/1.05, 취업여성 l/l.05/0.87로 나타나 취업여성이 전업여성에 비해서, 그리고 한국인 영양권장량의 기준(1/1/1)에 비해서 포화지방의 비가 낮았다. 또한 지방 에너지 구성비도 전업여성(24.38%)이 취업여성(23.29%)에 비해 높았고, 총 열량에 대한 동물성 지방의 섭취비율이 전업여성 12.44%, 취업여성 11.46%으로 나타나 전업여성이 취업여성에 비해 동물성 지방, 포화지방비, 지방에너지 구성비가 모두 높았다. 영양권장량에 대한 영양소 섭취 백분율에서 전업여성과 취업여성 모두 칼슘과 아연을 권장량에 비해 낮게 섭취하고 있었고, 질적 영양지수(INQ)도 두 군 모두에서 칼슘이 가장 낮게 나타났다. 인의 영양밀도(Nutrient Density)가 취업주부에서 높았던 점 외에는 영양밀도와 영양소 적정섭취비(NAR) 모두에서 비타민 B$_1$, B$_2$가 전업여성에 비해 취업여성이, 비타민 C가 취업여성에 비해 전업여성이 더 높았다. 한편 두 군 모두 INQ가 가장 높은 영양소는 인이었고, INQ가 가장 낮은 영양소는 칼슘으로 나타났으며, INQ가 1 미만인 영양소는 칼슘과 함께 철분으로 나타났다. 이는 1998년도 국민건강영양조사 결과에서 45세 이상 여성의 경우 관절염, 요통.좌골통, 디스크 등 근골격계질환 유병률이 남자보다 3배정도 높게 나타난 결과에 비추어볼 때 이들 관련 영양소에 대한 섭취 방안 지도의 필요성을 제시하고 있다. 결론적으로 고학력 중년 여성중 전업여성에 대해서는 지방 특히 동물성 지방 식품 섭취에 대한 적절한 영양교육과 식사관리 지도가 요구된다 하겠다. 또한 고학력 중년 여성은 취업 여부에 관계없이 칼슘과 철분이 많이 함유된 식품으로 식사량을 증가시켜 주는 영양 지도 및 영양 보강 대책이 요구되며, 칼슘과 인의 적정섭취비가 되도록 인의 섭취를 낮추는 식생활 지도가 필요하다.

We investigated the anti-inflammatory activities of various organic solvent extracts with and without Lactobacillus plantarum fermentation of Aralia continentalis Kitagawa which has hypotensive effects in addition to excitatory effects on the central nervous system. It has been used to treat arthritis, colds, neuralgia, rheumatism, and itchy skin. Our extracts were tested for their anti-inflammatory potential on NO production and the expression of inflammatory factors in lipopolysaccharide-stimulated RAW264.7 macrophages. Extracts with and without L. plantarum fermentation were prepared using water, ethanol, hexane, ethyl acetate, and butanol. The RAW264.7 cells were tested for toxicity and the anti-inflammatory activity of each extract was determined at a concentration with no toxicity to the cells. The extracts used in this study significantly inhibited both the production of NO and the mRNA expression of COX-2 and iNOS, the major inflammatory factors. The production of inflammation-related cytokines $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ was also significantly reduced. These results suggest that the extracts involving fermentation by L. plantarum can inhibit cytokines by controlling the expression of inflammatory cytokine genes. It is considered that the water, ethanol, and butanol extracts after fermentation with L. plantarum could be useful as functional natural materials with anti-inflammatory effects.

This study aims to evaluate the effect of sleep duration on obesity in Korean adult using data from the 8th Korea National Health And Nutrition Examination Survey in 2019. The study subjects were 5,213, and we performed frequency analysis, descriptive statistics, and multivariate regression analysis using the SPSS Win 27.0 program. The average sleep duration of the subjects was 6.8 hours per day, and the average body mass index (BMI) was 23.9 kg/m². As a result of bivariate analysis of factors affecting sleep duration, age, education level, stress, depression, diabetes, hypertension, and arthritis were significantly associated with sleep duration. The body mass index (BMI) of the group with less than 6 hours of sleep duration was 24.4, which was higher than that of other groups, and there was a significant negative correlation between sleep duration and BMI (B=-0.247; 95% CI=-0.334~ -0.160). In conclusion, in order to prevent obesity in adults, various efforts from the country and local communities are needed to increase sleep duration.

Purpose: Candida albicans can cause mucosal disease in many vulnerable patients. Also they are associated with denture-related stomatitis. Electrolyzed water is generated by electric current passed via water using various metal electrodes and has antimicrobial activity. The aim of this study was to investigate antifungal activity of electrolyzed water on C. albicans biofilm. Materials and Methods: C. albicans was cultured by sabouraud dextrose broth and F-12 nutrient medium in aerobic and 5% $CO_2$ condition to form blastoconidia (yeast) and hyphae type, respectively. For formation of C. albicans biofilm, C. albicans was cultivated on rough surface 6-well plate by using F-12 nutrient medium in $CO_2$ incubator for 48 hr. After electrolyzing tap water using various metal electrodes, the blastoconidia and hyphal type of C. albicans were treated with electrolyzed water. C. albicans formed blastoconidia and hyphae type when they were cultured by sabouraud dextrose broth and F-12 nutrient medium, respectively. Results: The electrolyzed water using palladium electrode (EWP) exhibited antifungal effect on blastoconidia of C. albicans. Also, the EWP significantly has antifungal activity against C. albicans biofilm and hyphae. In the electrolyzed water using various metal electrodes, only the EWP have antifungal activity. Conclusion: The EWP may use a gargle solution and a soaking solution for prevention of oral candidiasis and denture-related stomatitis due to antifungal activity.

Purpose: The purpose of this study was to investigate antifungal activity of shiitake mushroom yeast and hyphal type of Candida albicans. Materials and Methods: The extract from shiitake mushroom was collected by drying the supernatant after soaking shiitake mushrooms in water or ethanol. The antifungal activity of the extracts against yeast type of C. albicans was investigated by the susceptibility assay using microplate. C. albicans biofilm was formed on 12-well plate using Ham's F-12 medium in CO₂ incubator and treated with the ethanol extract. Furthermore, C. albicans biofilm was formed on denture base resin disk and treated with or without the ethanol extract in the presence of denture cleanser. Live C. albicans in biofilm was counted by cultured colony forming unit value after inoculated on agar plate. Results: Ethanol extract from shiitake mushroom showed stronger antifungal activity against yeast type of C. albicans compared to its water extract. The ethanol extract significantly reduced count of C. albicans in hyphal biofilm (P < 0.05). Also, the ethanol extract showed synergistically antifungal effect with denture cleanser on candidal biofilm on denture base resin disk (P < 0.05). Conclusion: The ethanol extract of shiitake mushroom may be a candidate for preventing candidal stomatitis as well as denture-related stomatitis.

Breast cancer related lymphedema (BCRL) is one of the most intractable complications after surgery. Patients suffer from physical impairment, as well as psychological depression. Moreover, a recent study revealed that cellulitis significantly increased the risk of BCRL, and cellulitis has been suggested as a risk factor of BCRL development. We describe a patient treated with stellate ganglion blocks (SGBs) without steroid for relief of symptoms and reduction of the arm circumference of breast cancer-related infectious lymphedema in a month. We measured the arm circumference at four locations; 10 cm and 5 cm above and below the elbow crease, numeric rating scale (NRS) score, lymphedema and breast cancer questionnaire (LBCQ) score on every visit to the pain clinic. A serial decrease of the arm circumference and pain score were observed after second injection. In the middle of the process, cellulitis recurred, we performed successive SGBs to treat infectious lymphedema. The patient was satisfied with the relieved pain and swelling, especially with improved shoulder range of motion as it contributes to better quality of life. This case describes the effects of SGB for infectious BCRL patients. SGB could be an alternative or ancillary treatment for infectious BCRL patients.
