ABSTRACT

Recently, we found and analyzed vitamin B12 in some Korean traditional plant foods which had not reported, yet. This study was to investigate vitamin B12 intake and its dietary sources and the vitamin B12 status in the very old elderly Koreans. We measured serum vitamin B12 level and estimated the amounts of vitamin B12 intake from different dietary sources in female elderly Koreans aged 85 and over who had consumed a relatively low animal traditional diet for the whole life. The average age of the subjects (n = 127) was 98.0 years (85-108 years). The assessment on energy and nutrient intake involved a one-day 24-hour recall, and serum vitamin B12 concentration was measured by radioimmunoassay. Overall diet pattern was not different between the 85-99 yr-old group and centenarians, except centenarians were taking more dairy product. The average ratio of plant food to animal food consumption was 87.5:12.5 in weight. The average vitamin B12 intake of our subjects was 3.2 microg/day, and 52.7% of subjects consumed under estimated average requirement, 2.0 microg/day. On dietary source, 67.3% of dietary vitamin B12 was from meat, eggs and fishes and 30.6% was from plant foods, such as soybean-fermented foods, seaweeds, and kimchi. The average serum vitamin B12 concentration was 450.5 pg/mL, and low serum vitamin B12 (< 200 pg/mL) was found in 9.6% of subjects. Dietary vitamin B12 intake was significantly lower in subjects with low serum vitamin B12 (0.79 microg/day) than those with normal serum vitamin B12 (3.47 microg/day). There were no significant difference in vitamin B12 intake and its dietary sources and serum vitamin B12 level between the 85-99 yr-old group and centenarians. In conclusion, several plant-origin foods including seaweed, soybean-fermented foods, and kimchi, may contribute significantly to good vitamin B12 status in very old elderly Koreans.

ABSTRACT

BACKGROUND: Granisetron, a new 5-HT3 receptor antagonist, was reported as a highly effective antiemetics, especially in combination with dexamethasone, in the prevention of acute emesis induced by cisplatin. But there is lack of data about effectiveness in the prevention of delayed emesis. In this study, the efficacy of granisetron plus dexamethasone in the prevention of delayed emesis induced by cisplatin was evaluated. MATERIALS AND METHODS: Sixty-four patients who were to receive high-dose cisplatin containing chemotherapy regimen were enrolled in this study. They were received 20 mg of dexamethasone and 3 mg of granisetron at 30 min and 10 minutes prior to cisplatin infusion, respectively. They were monitored for 5 days, first 24 hours for acute nausea/ vomiting and the subsequent 4 days for delayed nausea/vomiting. Antiemetic effect of granisetron was evaluated according to the criteria of Italian Group of Antiemetic Research. RESULTS: Control of delayed nausea and vomiting was achieved in 58% and 84%, respectively. Eastern Cooperative Oncology Group performance status was a statistically significant prognostic factor for control of acute vomiting and delayed nausea/vomiting. There were no stastically significant differences between control of delayed nausea/ vomiting and other prognostic factors, including sex, age, and prior history of cisplatin therapy. The antiemetic effect was greater in the patients who had controled acute nausea/ vomiting than those who had not. CONCLUSION: Granisetron plus dexamethasone is an excellent regimen in the control of not only acute emesis but also delayed emesis induced by high-dose cisplatin chemotherapy.
