중력분을 이용하여 제면한 후 가압가열, microwave 및 가압가열과 microwave 병행 처리한 후, 생면 및 삶은 면의 품질에 미치는 영향에 대하여 알아보았다. 생면의 pH는 microwave 1 min 처리구에서 무처리구와 유의적인 차이를 보이지 않았으며, 수분 함량은 autoclave 50 min 처리구에서 무처리구와 유의적인 차이를 보이지 않았고, 그 외의 처리구에서는 모두 수분 함량이 감소함을 확인하였다. 면의 색도 측정 결과는 명도는 무처리구에 비해 모든 처리구에서 감소하였으며, 적색도는 microwave 1 min 처리구는 감소한 반면, 나머지 처리구는 증가하였다. 황색도는 autoclave 50 min 처리구와 autoclave 50 min/microwave 1 min 병행 처리구에서 증가한 반면, 나머지 물리적 처리구에서는 감소하였다. 삶은 면의 색도에서는 명도, 적색도, 황색도 모두에서 무처리구에 비하여 물리적 처리구에서 증가한 값을 나타내었다. 물성 측정 결과는 경도, 부착성, 응집성, 검성, 복원성에서 무처리구와 비교시 microwave 1 min 처리구는 유의적으로 감소하였으며, 그 외 처리구에서는 유의적으로 증가한 값을 나타내었다. 탄력성과 전단력은 모든 처리구에서 유의적으로 증가하였으며, 인장력은 가압가열 30 min 처리구와 무처리구가 유의적인 차이를 보이지 않았으나, 나머지 물리적 처리구에서는 유의적으로 증가하였다. 관능 평가 결과는 생면의 경우 색 항목에서 물리적 처리구들이 유의적으로 낮은 점수를 받았다. 맛, 질감, 향 항목에서는 무처리구와 물리적 처리구간 유의적 차이를 보이지 않았다. 전체적인 기호도에서는 microwave 1 min 처리구가 가장 높은 점수를 얻었으며, 가압가열(50 min)과 microwave(1 min) 병행 처리구는 무처리구와 비슷한 점수를 얻었다. 따라서 제면 후 가압가열 및 microwave 처리가 생면 및 삶은 면에 있어서 색과 질감 항목을 보완, 개선시킨다면 알러겐성이 저감화된 면을 제품화하는데 적합할 것으로 사료되어진다. This study was conducted to determine the effects of physical treatments for quality of wet noodles. Noodles were being tried with a microwave (for 1 min), an autoclave (for 30 or 50 min), and both autoclave and microwave (for 30/1 min or 50/1 min). The results showed that the pH levels were slightly decreased after treatments of autoclave and autoclave/microwave. The moisture contents were considerably decreased as compared to the control except autoclave (50 min). After all treatments, the lightness was decreased in all samples, but, redness was increased (except microwave) and the yellowness was increased after autoclave (50 min) and autoclave/microwave (50/1 min). Texture was increased as compared to the control except microwave. In the sensory evaluation, the noodles treated with microwave, autoclave (50 min), and autoclave/ microwave (50/1 min) showed a high score in overall preference. From these results, both the autoclave and microwave methods can be applied to the wet noodles without diminishing its quality to a great extent.

김동원,이동호,민경호,전세웅,유희구,김경헌,승익상,김교상,서정국 대한마취과학회 1987 Korean Journal of Anesthesiology Vol.20 No.6

The introduction of muscle relaxants was an epoch making event in the development of clinical anesthesia and their use has hecame essential to anesthesia practice. Vecuronium, one of the newest muscle relaxants, many advantages; it is .apid acting, non-accumulating, has minimals side reactions and is promptly antagonized by anticholinesterases. However, its pharmacological effect, like other conventional muscle relaxants depends upon the dose and is influenced br many factors including body temperature, blood flow, interaction with other drugs, antibiotics, diuretics and so forth, To obtain a dose·response relationship which is important for clinical use, the effect of the vecuronium in various doses on the neuromuscular block in rabbits was investigated. The results were as follows. 1) In the vecuronium 0.025 mg/kg group, maximal twitch depression was varied between 75 to 92% with a mean value of 84,9%. The spontaneous recovery index was 141.0 seconds (2.35 min). 2) In the vecuranium 7.75 mg/kg group, thmean maximum twitch depression and spontaneous recovery index were 98.4% and 218.6 seconds (3.64 min.) respectively. 3) In the vecuronium 7.1 mg/kg group, maximum twitch depression was 100% and the spontaneous recovery index was markedly prolonged to 627.8 seconds (10.35 min).

김상태,배진호,김상범,임승운,민병상,신영덕 대한마취과학회 2000 Korean Journal of Anesthesiology Vol.38 No.3

Background : COPA (cuffed oropharyngeal airway) is a convenient device for airway management in patients undergoing general anesthesia for elective surgery in supine position. It causes less pharyngeal trauma than LMA(Laryngeal mask airway). The purpose of this study was to compare the effect of COPA with and without muscle relaxant. Methods : Forty patients with ASA physical status I and II for elective surgery were randomly assigned to two groups. Anaesthesia was induced with propofol (2 mg/kg) and vecuronium (1.5 mg/kg) and was administered intravenously in Group I but not in Group II. Mask ventilation was done for 5 min with 0: 5 L/min. COPA was placed and heart rate, and systolic, mean, diastolic blood pressure and peak inspiratory pressure were measured at 1 min interval for 5 min. Anaesthesia was maintained with pro- pofol 150 ㎍/kg/min, fentanyl 1 ㎍/kg/hr, O_2 2 L/min and N_2O 2 L/min. Results : There were no significant differences between Group I and Group II in heart rate, systolic, mean and dstolic blood pressure. PIP (Peak inspiratory pressure) was increased and hiccups occurred significantly (p $lt; 0.05) in Group II. Complete airway obstruction occurred in one patient of Group I and severe coughing, body movements and gagging occurred during induction and insertion in Group II. conclusions : With the use of appropriate muscle relaxant, we can use COPA without increased inspiratory pressure or significant complication.

The purpose of this study was to evaluate effects of Cordyceps militaris on fat oxidation during submaximal exercise. Fifteen healthy male collegiate students(ingestion group, N=7; control group, N=8) participated as subjects after signing an informed consent following overnight, subjects completed maximal graded execise test on treadmill to determine exercise intensity(50%VO2max). To evaluate the fat oxidation using indirect calorimeter, it was performed submaximal treadmill to determine exercise lasting. 40min at 50%VO2max after 5day and consumed Cordyceps militaris on separate days. This study was used 2×4 two way repeated ANOVA to analyze physiological and metabolic variables between two groups and metabolic variables between two groups and four exercise periods(l0min, 20min, 30min 40min), and used Scheffe to post-hoc test. Significance was set at α=.05. The results of this study were as followed: First, there were significantly highest in ingestion group for V02, percentage of fat oxidetion(%fat), fat per kilocarolies(Fkcal), and total per kilocarolies(Tkcal)(p<.05), but respiratory exchange ration(RER) and heart rete(HR) were significantly lower in ingestion group(p<.05). Second, RER, %fat, Fkcal were significantly difference in 10, 20, 30, 40min of exercise period(p<.05). This results suggest that there is the effect of Cordyceps militaris on fat oxidation submaximal exercise. Additionally, to evaluate effect of Cordyceps militaris as ergogenic aid, it should be required the future study that included extend subjects, various dosage, and chronic consumption.

민도준,양동원,민창기,김완욱,이상헌,박성환,김동욱,이종욱,조철수,민우성,김범생,김호연,김춘추 대한조혈모세포이식학회 2001 대한조혈모세포이식학회지 Vol.6 No.1

배경: 기존의 치료에 불응하고 예후가 불량한 자가면역질환 환자들에게 최근 고용량 면역억제 및 조혈모 세포이식이 새로운 치료방법으로 대두되고 있다. 저자들은 다발성 경화증(multiple sclerosis, MS) 및 류마티스 관절염(rheumatoid arthritis, RA) 등 2명의 자가면역질환 환자들에서 자가조혈모세포 이식을 시행하였다. 방법: 말초혈액 조혈모세포 가동화를 위하여 cyclophosphamide (4 g/㎡) 및 granulocyte colony stimulating factor (10 g/kg/day)를 투여하였고, CD34+ 세포를 분리·채집 하였다, 이식 전처치로 MS 환자에서 BEAM 및 antihymocyte globulin (ATG) (3.75 mg/kg), RA 환자에서 fludarabine (180 mg/㎡), ATG (10 mg/kg)와 busulfan (8 mg/kg)을 투여하였다. 결과: 호중구 수가 500/㎕ 이상으로 회복되는 기간은 MS 환자에서 9일, RA 환자에서 15일이었다. 혈소판이 20.000/㎕ 이상으로 회복되는 가간은 RA 환자에서 9일 이었고, MS 환자에서는 혈소판 감소증이 발생하지 않았다. 비혈액학적 독성으로 MS 환자에서 WHO 1도의 오심 및 점막염이 관찰되었다. MS 환자는 이식 6개월 후까지 시력감소가 남아있었으나, 이식전에 관찰되던 감각이상 및 운동장애 등의 신경학적 이상 소견은 더 이상 관찰되지 않았다. RA 환자는 이식 1개월 후 관절 증상 및 검사소견의 호전을 보였다. 결론: 불응성 자가면역질환 환자에서 고용량 면역억제 및 조혈모세포이식은 적은 독성으로 높은 치료효과를 기대할수 있으며, 향후 이 시술의 임상적 의의를 규명하기 위하여 전향적이고 장기적인 연구가 필요할 것으로 사료된다. Background: High-dose immunosuppressive therapy followed by autologous hemathpoietic stem cell transplantation (HSCT) has been proposed as a new approach to treat severe, refractory autoimmune diseases. We describe two patients with refractory autoimmune diseases (one multiple sclerosis 〔MS〕and one rheumatoid arthritis〔RA〕) who underwent T-cell-depleted autologous peripheral bleed stem cell transplantation for the first time in Korea. Methods: We mobilized autologous stem cells with cyclophisphamide (4 g/㎡) and granulocyte colony-stimulating factor (10 ㎍/kg/day). Stem cells were enriched ex vivo using CD34-positive immunoselection and reinfused after high-dose chemotherapy with BEAM and antithymocyte globulin (ATG) (3.75 mg/kg) in MS, or fludarabine (180 mg/㎡), ATG (10 mg/kg) and busulfan (8 mg/kg) in RA. Results: The engraftment with an absolute nerutrophil count greater than 500㎕ occurred on day 9 in MS and 15 in RA, respectively. The time to nontransfused platelet count greater than 2.000/㎕ was 9 day in RA. MS patient did not show ant episode of thrombocytopenia. Regimen-related non-hematopoietic toxicity was minimal. For 6 months since HSCT, them patient with MS had been free from previously existed sensory and motor abnormalities except decreased visual acuity. Then patient with RA and only one tender joint and two mildly swollen joints with improvement in laboratory parameters at one month after HSCT. Conclusion: These results underscore the feasibility and potential efficacy of intensive immunosuppression followed by autologous HSCT for treatment of intractable autoimmune diseases. The durability of remission, however, remains to be clarified.

Jong Min Kim,Jong Hyun Moon,Min Ji Kim,Hyo Lim Lee,Hye Rin Jeong,Min Ji Go,Tae Yoon Kim,Seung Gyum Joo,Jong Cheol Kim,Ho Jin Heo 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

This study was performed to evaluate the protective effect of matcha green tea on particulate matter (PM)2.5-indued nasal and pulmonary cytotoxicity. The matcha green tea increased the cell viability and inhibited the ROS production in PM2.5-induced cytotoxicity in nasal RPMI2650 and pulmonary A549 cells. The matcha green tea regulated the expression of apoptosis, such as p-Akt, BCl-2, caspase-3, caspase-1 and HO-1, and inflammation, such as TLR4, TLR4 and Nrf2, in PM2.5-indued RPMI2650 cells. In addition, the matcha green tea showed regulatory effect of the apoptosis and inflammatory effect by increasing the BCl-2 and suppressing the caspase-3, TLR4, TNF-α and COX-2 in A549 cells. In addition, the matcha green tea suppressed antioxidant deficits by regulating the reduced GSH contents, SOD activities and MDA levels, and ameliorated the mitochondrial dysfunction by regulating the mitochondrial ROS production, mitochondrial membrane potential and ATP contents in pulmonary tissue. Ultimately, consumption of matcha green tea down-regulated the inflammatory proteins such as TNF-α, p-JNK, p-IκB-α, p-NF-κB and COX-2 in lung tissue.
