To develop customized food products for gastric cancer patients, it is crucial to understand their dietary characteristics and changes in their perception of smell and taste due to their condition. This study conducted in-depth interviews and administered olfactory and gustatory tests on 20 patients with gastric cancer. A control group of 20 healthy, gender and age matched individuals, was included for comparison. Patients reported difficulties in sustaining their appetite, particularly during chemotherapy. This could be attributed to gastrointestinal discomfort and an altered perception of smell and taste. The olfactory test revealed that cancer patients were significantly less sensitive than the control group. Also, a smaller number of participants in the cancer group were reported to have a normal taste function, which enabled them to perceive umami, one of the five basic taste compared to those in the control group. These findings demonstrated that gastric cancer patients experience post-surgical digestive issues, chemotherapy-induced changes in smell and taste, and appetite loss. To improve the quality of life of these patients and the efficacy of the treatment, it is necessary to consider not only their nutritional requirements but also other factors such as appetite loss and discomfort when developing meals specifically for them.
Comparing the quality characteristics of kimchi were measured and anticancer effects using AGS human gastric cancer cells were observed. Five kinds of kimchi samples were made of Kanghwa Baek kimchi (KB), Kangwha Turnip kimchi (KT), Turnip: Chinese cabbage = 1:1 Baek kimchi (T1B1), Turnip:Chinese cabbage = 4:1 Baek kimchi (T4B1), Turnip mul kimchi (T). As a result T kimchi showed the best fermentation characteristics among the five samples. T kimchi had a lower percentage of the total number of aerobic bacteria, while the number of lactobacillus was higher than that of other samples. The mRNA and protein expression levels of apoptosis-related factors found that T kimchi significantly increases the mRNA expression levels of caspases-3 and caspases-9 in AGS human gastric cancer cells as compared to the other kimchi samples. It showed high anticancer effects in the order of T, T1B1, and KB kimchi. As the anticancer effect of Turnip mul kimchi made only of turnip was higher, the higher the turnip content, the higher the anticancer effect. These results show that there were changes in fermentation characteristics such as pH, acidity, number of lactic acid bacteria, and anticancer effects according to the ratio of turnip and cabbage.
Although the age-standardized incidence of gastric cancer has decreased in Korea, it remains the second most common type of cancer. The purpose of this study was to analyze the phospholipid fatty acid compositions of gastric mucosa in gastric cancer. Cancerous mucosa and noncancerous mucosa adjacent to cancerous tissues were obtained from 29 patients who had undergone gastrectomy for gastric adenocarcinoma. Phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatidylserine (PS) were separated from phospholipids by thin-layer chromatography, and fatty acids were analyzed by gas chromatography. In cancerous mucosa, saturated fatty acids of total phospholipids and stearic acid of PE and PC contents as well as total phospholipids were significantly more abundant than in noncancerous tissues. The ratios of ω6 fatty acid products to linoleic acid of PC, PE, PI, and PS contents as well as total phospholipids were significantly higher in cancerous mucosa than in noncancerous mucosa. Arachidonic acid levels of PE and PI were significantly higher, but the PC level was lower in cancerous mucosa. These results suggest that the characteristic differences in fatty acid compositions of phospholipids and their subfractions shown in gastric cancerous mucosa may be affected by changes in lipid metabolism in gastric carcinogenesis. Further studies on structural and functional changes in phospholipids related to gastric carcinogenesis will be needed.
이전에 합병증 없이 내시경 역행성 담췌관 조영술(ERCP)을 여러 번 시행받은 71세 남자 환자에게 내시경 삽입 중 식도 점막 파열이 발생하였다. 점막열상은 내시경클립(endoclip) 을 사용하여 성공적으로 봉합되었으나, 이 합병증으로 인해 식도암과 조기 위암이우연히 동시에 발견되었다. 십이지장경은 위장관, 특히 식도 관찰에 제약이 있기 때문에 임상적으로 중요한 병변을 놓칠 가능성이 있다. 따라서 점막 손상이나 천공을 예방하기 위해 내시경선단에 충분한 윤활제를 도포하는 것과 함께 ERCP 중 상부내시경 검사를 시행하는 것도 고려 되어야 한다. 어느 환자군에서 ERCP 중 상부내시경 검사가 유용할지에 대해서는 향후 대규모 연구가 필요할 것이다.
위암의 전이는 주로 혈행성 전파, 림프절을 통한 전이, 주위 장기를 통한 직접 침윤과 복강내 파종을 통해 이루어지며 장 기로는 주로 간, 폐, 뼈로 전이가 된다고 알려져 있다. 위암의 담낭 전이는 흔하지 않고 예후가 좋지 않으며 담낭염으로 발현한 경우 더 예후가 나쁘다고 알려져 있다. 본 저자들은 위암 의 담낭으로의 전이와 담낭염이 동반된 증례를 경험하여 보고 하는 바이다.
배추김치 제조 후 익힘 시간 및 김치 냉장고 저장 기간에 따른 김치의 위 암세포 증식 억제 효능 변화를 측정해 본 결과, 저장 30일 김치 시료 기준으로 익힘 과정을 거치지 않은 S0h 시료에 비하여 46시간의 익힘 과정을 거친 S46h 시료의 효능이 가장 우수하였고, 이어서 S47h, S48h 시료의 효능이 우수하였다. 그리고 S0h 경우는 상대적으로 암세포 증식 억제 효능이 가장 약하였다. 이는 적정 발효에 따른 발효 대사산물, 그리고 유산균 속 및 종 변화에 기인한 결과로 판단되며, 항암 효능 보유물질로 알려진 GABA의 농도와도 연관이 있을 수 있음을 제안해 주고 있다. 김치는 다양한 재료 유래의 기능성 물질, 대사산물 및 유산균을 보유하고 있는 발효식품이다. 따라서 본 연구는 김치제조 후 최적의 숙성 시간과 저장 기간을 선택하면 항암 기능성이 증진된 김치를 섭취할 수 있는 것을 제안해 주고 있다.
This study was designed to investigate the effect of fucoidan on the activation of macrophage and on induction of apoptosis in AGS cell. To measure the activity of macrophages, NO and TNF-α assays were performed in Raw 264.7 cell. Treatment with fucoidan significantly increased production of NO and TNF-α, indicating activation of macrophages. The result of MTT assay shows that cell viability was significantly decreased in a dose and time-dependent manner. Fucoidan increased to enhance mitochondrial membrane permeability, as well as the cytochrome c release from the mitochondria. Fucoidan decreased Bcl-2 and XIAP expression, whereas the expression of Bax was increased in a time-dependent manner compared to the control. In addition, the active forms of caspase-9 were increased, and the inactivation of Akt was decreased in a time-dependent manner. Caspase inhibitor, z-VADFMK, canceled the apoptosis of fucoidan, expression of Bax and caspase-9 were decrease. These results indicate that fucoidan induces activation of macrophage and apoptosis through activation of caspase on AGS cell.
The clinical importance of biologic markers remains elusive in gastric cancer. The aim of this study was to evaluate the prognostic value of p53, Ki-67, and COX-2 in gastric cancer. This retrospective study examined based on medical records of postoperative immunohistochemical test of 176 patients who demonstrated high expression of all three biological markers being tested (p53, Ki-67, and COX-2), among 357 gastric cancer patients who underwent surgical resection consecutively. This study demonstrates the correlation with biologic marker between clinical relationship and recurrence free survival (RFS). A positive correlation was observed between the expression of Ki-67 and p53, and a positive correlation was also observed between the expression of Ki-67 and COX-2 Expression of p53 did not correlate with any of the clinicopathological variables examined. Both Ki-67 and COX-2 expression significantly correlated with tumor depth, classified as early gastric cancer and advanced gastric cancer. The expression of COX-2 significantly correlated with tumor differentiation, with more tumors being of the undifferentiated type than of the differentiated type in the COX-2 positive group. A significant difference between p53 and RFS, also COX-2 expression and RFS was observed. This study showed that only p53 and COX-2 have significantly correlated with the RFS of gastric cancer.
The aim of this study is to evaluate satisfaction with critical pathway (CP) in nursing gastric cancer patients. From January to June 2008, non critical pathway group (NCPG, n=28) is used by general doctor’s order. However, from July to December 2008, critical pathway group (CPG, n=25) received the CP schedule applied by the PA on the pre operative day. The collected data were analyzed by chi-square, and student t-test using the SPSS/Win 12.0 program. Patient’s satisfaction increased with understanding of disease and treatment process, explanation of related study and treatment, education regarding activity status, and degree of confidence in doctor. Patient satisfaction was higher in the CPG than in the NCPG.
