ABSTRACT
@#Sports drinks consist of water, carbohydrates, and electrolytes specially formulated for athletes or individuals in need. However, coaches from the National Coaching Academy division experience budget constraints to obtain commercial sports drinks on a large scale to meet the needs of all athletes. Therefore, an experimental study was conducted to produce a low-cost isotonic sports drink (Rose Lemonade) with white sugar and brown sugar and evaluate its acceptance among university students through sensory evaluation. This study involved 50 panels with 25 students from UKM (nonathletes) and 25 students from UM (athletes). The overall acceptance of brown sugar Rose Lemonade has an average score of 3.52 ± 0.97 compared to white sugar Rose Lemonade, which is 3.50 ± 1.07. The data analysis showed a nonsignificant difference in the Kruskal Wallis test (p>0.05) for the overall acceptance of both types of sports drinks. In conclusion, this study showed that both white sugar and brown sugar Rose Lemonade isotonic sports drink formulations were acceptable to the panels. The findings of this study provide the formulation of cheap, and easy-making sports drinks. A suggestion for future research is to test the effectiveness of energy supply and electrolytes replacement and shelf life of this sports drink and produce a variety of flavors to meet individual tastes.
ABSTRACT
Abstract The aim of the present work was to design new beverages using lemonade and some herbal extracts (linden, heather, green tea, lemon verbena, clove, peppermint, ginger and mate) rich in vitamin C and flavonoids. The linden-added lemonade showed the highest value (597.9 mg/kg) for ascorbic acid content, whereas the lemon verbena-added lemonade showed the lowest value (486.04 mg/kg). The amount of saccharose was changed by 11.07-11.58%, the glucose by 1.11-1.62% and the fructose between 11.07-11.58% in the beverages. K, Na, Mg and P values in the lemonades were determined in the range of 178.83-210.98 mg/kg, 33.75-39.13 mg/kg, 22.37-27.89 mg/kg and 7.22-10.04 mg/kg, respectively. The total phenolic content in the samples changed between 315.11-397.57 mg GAE/100 g. When the samples were analyzed for antioxidant activity, FRAP (17.13-26.79 µmol trolox/mL) and ABTS (16.91-25.38 µmol trolox/mL) methods gave higher results than the DPPH (14.88-17.72 µmol trolox/mL) method. Linden-, ginger- and peppermint-added lemonades, which had been found to be rich in total phenolic compounds and ascorbic acid, showed higher antioxidant activity than the control sample. Overall, the most preferred lemonades were heather- and ginger-added beverages and the control sample. Mate-added lemonade was the least preferred.
ABSTRACT
<b>Purpose</b>: Ketamine is effective on neuropathic pain that is difficult to respond to opioids among cancer pains, due to its N-methyl-D-aspartate (NMDA) receptor antagonism action. The purpose of this study was to evaluate the effect of oral ketamine on neuropathic pain. <b>Methods</b>: We retrospectively investigated the dosage and the administration period of oral ketamine in 31 patients for one year from December 2004. <b>Results</b>: Pain-relief was achieved in 22 of 31 patients, the average of initial dose was 107.3mg/day and the average administration period was 63 days. Seven patients discontinued oral ketamine within 7 days because of nausea/ vomiting (4 patients) or drowsiness (3 patients). Two patients had no sufficient pain-relief. <b>Conclusion</b>: This experience suggests that oral ketamine is effective on the management of neuropathic pain. Palliat Care Res 2008; 3(1): 216-220
