Purpose: It is well known that old age is a risk factor for postoperative complications. Therefore, this study aimed to explore the risk factors for poor postoperative surgical outcomes in elderly gastric cancer patients. Materials and Methods: Between January 2006 and December 2015, 247 elderly gastric cancer patients who underwent curative gastrectomy were reviewed. In this study, an elderly patient was defined as a patient aged ${\geq}65$ years. All possible variables were used to explore the risk factors for poor early surgical outcomes in elderly gastric cancer patients. Results: Based on multivariate analyses of preoperative risk factors, preoperative low serum albumin level (<3.5 g/dl) and male sex showed statistical significance in predicting severe postoperative complications. Additionally, in an analysis of surgery-related risk factors, total gastrectomy was a risk factor for severe postoperative complications. Conclusions: Our study findings suggest that low serum albumin level, male sex, and total gastrectomy could be risk factors of severe postoperative complications in elderly gastric cancer patients. Therefore, surgeons should work carefully in cases of elderly gastric cancer patients with low preoperative serum albumin level and male sex. We believe that efforts should be made to avoid total gastrectomy in elderly gastric cancer patients.

본 실험은 강제환우가 난질 및 계란의 저장기간에 따른 계란품질의 변화를 구명하고자 실시하였다. 실험에 공시된 계란은 환우하지 않은 60주령된 ISA Brown 노계의 계란을 대조구 (Control), 55주령에 환우를 실시한 처리구1 (T1), 70주령에 환우를 실시한 처리구2 (T2)를 각각 240수씩 총 720수를 공시하였다. 사료는 시중에서 유통되고 있는 산란사료를 사용하였다. 산란율이 50%에 도달하였을 때 정상란을 채집하여 난각 및 내 외부 난질을 저장 1일, 3일, 6일, 9일, 12, 15일에 조사하였다. 난각강도는 강제환우를 시키지 않은 60주령의 일반란과 70주령에 환우를 실시한 처리구보다 55주령에 강제환우를 실시한 처리구에서 난각강도가 유의하게 (p<0.05) 높게 나타났다. 난각두께는 각 처리구간 혹은 저장기간별로 일정한 경향이 나타나지 않았다. 난각색과 난중은 대조구인 60주령과 환우처리를 실시한 두 처리구간 및 저장 기간에 따른 일정한 경향이 이를 나타나지 않았다. 난백고는 환우를 수행하지 않은 대조구가 환우를 실시한 두 처리구보다 더 높았으며 강제환우를 실시한 두 처리구간에는 유의적인 차이가 없었다. 또한 저장기간이 길어질수록 환우처리에 관계없이 난백고가 낮아지는 경향을 보였다. Haugh unit는 강제환우 처리를 한 두 처리구가 대조구에 비해 유의하게 낮았다 (p<0.05). 또한 저장기간이 길수록 세 처리구 공히 Haugh unit가 현저하게 감소하여서, 난백고와 비슷한 경 향을 보였다. 난황색은 환우처리별, 혹은 저장기간 별로 일정한 경향을 보이지 않았다. 이상의 결과에서 산란계에 대한 강제환우는 난각강도를 개선하는 효과가 있었으나, 난백의 높이 및 Haugh unit는 오히려 감소시키는 것으로 나타났다.

Background: Extracorporeal membrane oxygenation (ECMO) has been widely used in patients with cardiorespiratory failure. The serum albumin level is an important prognostic marker in critically ill patients. We evaluated the efficacy of using pre-ECMO serum albumin levels to predict 30-day mortality in patients with cardiogenic shock (CS) who underwent venoarterial (VA) ECMO. Methods: We reviewed the medical records of 114 adult patients who underwent VA-ECMO between March 2021 and September 2022. The patients were divided into survivors and non-survivors. Clinical data before and during ECMO were compared. Results: Patients' mean age was 67.8±13.6 years, and 36 (31.6%) were female. The proportion of survival to discharge was 48.6% (n=56). Cox regression analysis showed that the pre-ECMO albumin level independently predicted 30-day mortality (hazard ratio, 0.25; 95% confidence interval [CI], 0.11-0.59; p=0.002). The area under the receiver operating characteristic curve of albumin levels (pre-ECMO) was 0.73 (standard error [SE], 0.05; 95% CI, 0.63-0.81; p<0.001; cut-off value=3.4 g/dL). Kaplan-Meier survival analysis showed that the cumulative 30-day mortality was significantly higher in patients with a pre-ECMO albumin level ≤3.4 g/dL than in those with a level >3.4 g/dL (68.9% vs. 23.8%, p<0.001). As the adjusted amount of albumin infused increased, the possibility of 30-day mortality also increased (coefficient=0.140; SE, 0.037; p<0.001). Conclusion: Hypoalbuminemia during ECMO was associated with higher mortality, even with higher amounts of albumin replacement, in patients with CS who underwent VA-ECMO. Further studies are needed to predict the timing of albumin replacement during ECMO.

Pentastarch is a hydroxyethyl starch similar to hetastarch, but lower average molecular weight and fewer hydroxyethyl groups which result in enhanced enzymatic hydrolysis and faster renal elimination.This report was performed to compare the clinical efficacy and safety of 10 % pentastarch[Pentaspan , group I] for plasma volume expansion after open heart surgery with that of 5% albumin[Plasmanate, group II]. There were no statistically significant differences between the group I [n=18] and group II [n:19] in the preoperative parameters [age, sex, body weight] and operative parameters[bypass time, aorta cross clamping time]. During the first 24 hours after arrival of the patient in the surgical intensive care unit, colloid solution [500--1000 ml] was infused to maintain left atrial pressure of more than 8 mmHg, or cardiac index of 2.0 L/min/M2 of more. In results, there were 3 complications of hypotension immediately after infusion of 5 % albumin solution and 2 among the 3 patients were excluded for the study. However there was no complication after infusion of 10 % pentastarch solution. Hemodynamic responses to infusion was similar for both groups, although in group I a greater increase in both left atrial pressure[mean 1.8 versus 0.7 mmHg, p< 0.05] and right atrial pressure [mean 2.2 versus 1.7 mmHg, p < 0.05] was observed during infusion of the first 500 ml. There were no significant differences in any of the measured respiratory parameters[PaO2, intrapulmonary shunt, and effective lung compliance]. Homodilution with colloid significantly reduced hemoglobin [mean 1.2 versus 0.8 gm/dl], and serum protein and albumin level[total protein;4.8$\pm$ 0.5 versus 5.2 $\pm$0.5 gm/dl, p < 0.05: albumin: 3.2 $\pm$0.4 versus 3.6 $\pm$0.6 gm/dl, p < 0.05] by 6:00 AM on 1 day postoperatively, however there were no significant differences on 7 day postoperatively. The mean serum colloid osmotic pressure and osmolarity was similar in both group.There were no abnormal findings of liver function and kidney function in all the patients. There were no significant between-group differences in bleeding time, platelets, prothrombin time, activated partial thromboplastin time and amount of chest tube output measured on 1st and 7th postoperative day. These findings demonstrated that 10% pentastarch is more effective and safe for plasma volume expension than 5 % albumin solution with no adverse effects on coagulation. Also 10 % pentastarch is less expensive than 5 % albumin and it would appeare to be a reasonable first choice for plasma volume expansion.

항산화, 항암 및 항염증 효능 등의 생리 활성이 보고된 우엉 뿌리의 열수 추출물을 제조하여 advanced glycation end products (AGEs) 형성 저해 효과를 확인하였다. AGEs는 bovine serum albumin (BSA)과 단당류인 glucose, fructose, galactose를 혼합하여 $37^{\circ}C$에서 3주간 배양하여 생성하였고 매주 형광도 측정, fructosamine 분석, ${\alpha}$-dicarbonyl compounds 함량 분석을 통해 AGEs의 생성량을 확인하였다. 우엉 뿌리 추출물의 AGEs 생성 저해능을 AGEs 생성 억제제로 알려져 있는 aminoguanidine (AG)의 저해능과 비교하였다. 우엉 뿌리 추출물은 BSA와 단당류인 glucose, fructose, galactose 각각의 당화반응을 억제하였으며 특히 배양 3주차에서 BSA와 glucose의 당화반응 결과물인 AGEs 생성을 유의적으로 저해하였다. 농도 2 mg/mL 이상의 우엉 뿌리 추출물은 1 mM AG보다 AGEs 생성 저해능이 우수하였으며 농도 4 mg/mL의 우엉 뿌리 추출물은 배양 3주차에서 AGEs 생성을 약 80% 이상 억제하는 효능을 나타냈다. 체내 혈당은 당뇨병과 같은 질환과 식이의 영향을 받으므로 다양한 glucose 농도에서 우엉 뿌리 추출물의 AGEs 생성 억제능을 조사하였다. 그 결과 AGEs 생성은 glucose의 농도에 비례하여 증가하였으며 우엉 뿌리 추출물은 당뇨환자의 식후에 관찰되는 혈당인 25 mM glucose 군에서 1 mM의 AG보다 높은 우수한 저해 효과를 확인하였다. 본 연구 결과는 우엉 뿌리 추출물의 AGEs 생성 억제라는 새로운 기능성을 밝히며 향후 당뇨 합병증 예방 효능을 가진 기능성 식품으로의 개발 가능성을 제시한다.

본 연구는 중년여성을 대상으로 8주간 걷기운동과 아사이베리 섭취를 통하여 심혈관 질환의 위험요인인 염증지표에 미치는 영향을 알아보고자 하였다. 연구대상자는 40-50대의 경기도 A시에 거주하는 심혈관 질환 및 대사성 질환이 없고 규칙적으로 운동에 참여한 경험이 없는 신체적으로 건강한 사람을 대상으로 아사이베리 섭취그룹(AB), 걷기운동과 아사이베리 섭취그룹(WE+AB), 걷기운동그룹(WE)으로 구분하여 걷기운동은 8주, 주 3회, 일일 60분간 실시하고 아사이베리 섭취는 8주, 매일 아침, 저녁 식사 전 5g을 100㎖의 물과 함께 희석시켜 섭취하고 8주 전 후 심혈관 질환의 위험요소인 염증지표를 살펴보였다. 그 결과 아사이베리 섭취그룹, 걷기운동과 아사이베리 섭취그룹, 걷기운동그룹의 염증지표 변인인 WBC(white blood cell), Albumin, ESR(erythrocyte sedimentation rate), CRP(C-reactive protein)에서 긍정적인 향상을 보였으며 Albumin에서만 유의하게 감소하였다. 따라서 8주간 걷기운동과 아사이베리 섭취를 통하여 심혈관질환의 위험요소인 염증지표를 개선하기에는 다소 기간이 부족하다고 사료되며 향후 염증지표의 개선의 효과를 위해서는 8주 이상의 장기간 운동과 아사이베리 섭취에 대한 추후 연구와 운동방법, 강도 및 섭취량 등의 다양한 연구가 필요하다고 사료된다.

This study was conducted to identify appetite and nutritional status of 48 cancer patients who have been irradiated over 150$\textrm{cm}^2$ on chest or pelvic area over the three-month period. The data were gathered 3 phases, Each from initiation to completion of radiotherapy through the questionnaires of anorexia, the anthropometric and biochemical measures were used such as weight, TSF, MAC, MAMC, serum albumin and hemoglobin, TLC. Using SAS program, data were analyzed by percentage, Mean$\pm$SD, and two-way repeated measures ANOVA. The results were summarized as follows : 1. Eighty five percent(85%) of the subjects were aged from fifties to sixties. Cancers in the chest area occurred in 100% of men, 56% of the all subjects. The other 44% were pelvic cancer and 71% of the pelvic cancer occurred in women. 2. There were no significant differences in the appetite scores by all groups(characteristics). Changes of the appetite score over time were statistically significant by age, sex, cancer areas staging, treatment modality, and radiation dosage (F=4.0, p=.022; t=6.09, p=.003; t=4.90, p=.009; F=3.28, p=.042; t=5.04, p=.0084; t=4.76, p=.011). The appetite score on the 2nd phase (4 weeks after initiating radiotherapy) decreased from the 1st phase (initiating irradiation), and then increased on the 3rd phase (completing irradiation). 3. There were no significant differences in the body weight and MAMC by all characteristics, and no changes in the body weight and MAMC over time. However there were significant differences of TSF, MAC, level of hemoglobin, level of albumin, and TLC by all characteristics during the three phases. TSF of the men and the chest cancer were lower than those of the women and the pelvic cancer (t=73.20, p=.0001; t=22.91, p=.0001). And there was significant difference by cancer staging(F=3.19, p=.050). But there was no change in TSF over time. MAC of the men and the chest cancer were lower than those of the women and the pelvic cancer each(t=9.23, p=.004; t=17.85, p=.0001). But no change in MAC over time. Levels of hemoglobin had significant differences by age, sex and cancer areas; levels of hemoglobin of older than the fifties, men, and chest area were higher than those on the others(F=3.82, p=.029; t=21.75, p=.0001; t=8.71, p=.005). Levels of albumin were significant differences by sex and cancer areas; levels of albumin on women, and pelvic area were higher than those on the others(t=6.34, p=.015; t=15.23, p=.0003). While the levels of hemoglobin were changed over time, levels of albumin were not changed and within normal limit. TLC of the men was higher than women(t=5.05, p=.029). Changes in the level of hemoglobin over time were statistically significant according to sex, cancer areas, and radiation dosage(t=3.49, p=.035; t=3.36, p=.039; t=4.04, p=.021).

Therapeutic drug monitoring of Mycophenolate mofetil(MMF) has been suggested in some clinical trials, but has not been widely adopted in Korea. The purpose of this study was to analyze the withdrawal rates of MMF and determine the characteristics of the patients who experienced adverse reactions with MMF therapy and to suggest the criteria for selecting patients who need monitoring of MMF levels. We retrospectively collected data of patients who started MMF between July 2007 and June 2008. A total of 154 adult patients were included in our study. Among them, ninety seven patients discontinued MMF with 59 cases being due to adverse drug reactions. Thirty one patients required dosage reduction of MMF with twenty three cases being due to adverse reactions. Twenty six patients continued the MMF without or with mild adverse reactions. Of the 82 adverse reaction cases, hematologic adverse reactions accounted for 38 cases (46%) and gastrointestinal (GI) adverse reactions accounted for 28 cases (34%). Older age and lower serum albumin levels were significantly different characteristics between the patients who withdraw MMF due to hematological adverse reactions and those who were able to continue therapy. The group who experienced GI adverse reactions had higher MMF dosages based on body weight and lower serum albumin levels. In conclusion, the factors affecting the adverse reactions of MMF were age, serum albumin level and higher dosage, therefore therapeutic drug monitoring of MMF should be considered in these patients.

To elucidate the relationship between blood parameters related bone metabolism and antioxidant enzyme activity in postmenopausal period 60 women residing in Iksan area were recruited. Food and nutrient intake of each individual subject were estimated by 24-hour recalls of 3 non-consecutive days. The biochemical markers including total protein, albumin, osteocalcin (intact bone gla protein; BOP), calcium, phosphorus and hemoglobin were measured in fasting blood. In addition, parameters of antioxidative capacity including the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) , catalase (CAT) and total antioxidant capacity (TA) were monitored in blood, also. The mean age, height, weight, and BM! of subjects were 64.8 years, 151.1 em, 59.5 kg $26.0\;kg/m^2$, respectively. The mean SOD, GPx, and CAT activities were 138.5 U/ml, 1,273.8 U/ml and 314.3 kU/l respectively, and TA was 1.16 mmol/l without significant difference among different age groups. BMI was positively correlated with SOD activity (p < 0.01). SOD activity and CAT activity showed positive correlation with serum albumin (p < 0.05) and hemoglobin (p < 0.01). In conclusion, this study revealed that antioxidant enzyme activity holds a significant relationship with the blood parameters like as serum albumin and hemoglobin in postmenopausal women and further systematic research is needed to investigate the their relation mechanism.

The purpose of this study was to investigate the nutritional status before and after gastrectomy of gastric cancer patients in Jeonbuk Province. The subjects were 136 patients with gastrectomy of gastric cancer. We assessed the nutritional status before and after an operation by general characteristics (age, clinicopathological stage, type of operation, method of reconstruction), anthropometric characteristics (height, weight, skeletal muscle mass, body fat mass, body mass index (BMI), percent body fat, arm muscle circumference AMC, arm circumference AC) and biochemical characteristics (hemoglobin Hb, hematocrit Hct, mein corpuscular volume MCV, mean corpuscular hemoglobin MCH, total lymphocyte count TLC, serum albumin, serum transferrin). Mean ages were 60.0 yrs in males and 58.8 yrs in females. Age, clinicopathological stage, types of operation and reconstruction methods were not significantly different between males and females. Weight, skeletal muscle mass, body fat mass, BMI, percent body fat, AMC and AC significantly deteriorated by gastrectomy. There were severe weight losses in males and females after gastrectomy. Hemoglobin, Hct, MCV, MCH, TLC, albumin and transferrin significantly deteriorated by gastrectomy. After gastrectomy, subjects who were assessed as malnounrished in Hb and Hct were increased in male and those who were assessed as malnounrished in Hb were increased in females. These results suggest that a nutrition intervention, specially for energy, protein and iron, is necessary to improve the nutritional status of gastric cancer patients with gastrectomy.
