  A sixteen weeks experiment was conducted to evaluate the effect of feeding CPO and RPO enriched palm sugar on liver retinol and immunoglobulin G (IgG) concentration in vitamin A depletion rats. Thirty-four-weeks old-male Sprague Dawley rats were received the standard diet (AIN-93M) for two weeks as adaptation period, after that 24 rats followed by vitamin A-free diet, for 10 weeks as a depletion period and of six remaining rats were given the standard diet as a control group. The depleted rats were then divided into 3 groups and received daily for 4 weeks as repletion period either a red palm oil (RPO) or crude palm oil (CPO) enriched palm sugar, or retinyl palmitate (RE) which each treatment contain approximately 40 μg beta carotene. Rats were blood-sampled at week 2 and week 4 and liver retinol and immunoglobulin G (IgG) concentration were determined. The body weight was taken every 5 days. Increasing on liver retinol concentration in rat administered retinyl-palmitate was higher than in rat administered CPO or RPO enriched palm sugar (p = 0.0136) which the increased in RE, CPO and RPO groups of 115.4, 86.4 and 61.7%, respectively. However, administering of enriched palm sugar both of CPO and RPO for 2-4 weeks can improve vitamin A status to above cut off point which increase from 0.063 μmol/g liver up to 0.107-0.117 μmol/g liver in CPO group and 0.079-0.102 μmol/g liver in RPO group. On the other hand, serum immunoglobulin G (IgG) level of animal administered palm sugar containing CPO or RPO were higher than in rat administered retinyl palmitate (p = 0.0073), which is indicated by increasing levels of serum IgG in both groups of CPO and RPO, that is equal to 225 and 216.01 percent, respectively compared to RE group of 59.98 percent. From this research we conclude that coconut palm sugar enriched with CPO or RPO were potentially as food-based intervention to overcome vitamin A deficiency.

  Background and Objectives: Bilih fish is a potential local food of West Sumatera, Indonesia and it is high in zinc. Fish flour, including that of Bilih fish, is a processed fish product that has not been primarily utilized for food. The levels of zinc in fish flour range from 12.83-22.92 mg. Hence, Bilih fish flour can serve as an alternative food source of zinc for people with diabetes mellitus, who usually exhibit low serum levels of zinc. This study aimed to analyze the effect of Bilih fish flour on the levels of blood glucose, MDA and SOD in diabetic rat models. Materials and Methods: This study used a Randomized Complete Design (RCD). Twenty-four white male rats of the Sprague-Dawley strain were placed into the following four groups: Normal and diabetic rats that were fed either the standard feed or Bilih fish flour with a zinc dose of 27 mg kg1 of feed and 13.5 mg kg1 of feed. A single dose of Streptozotocin (STZ) (40 mg kg1) was used to induce diabetes in the rats. The intervention lasted for 14 days. The data obtained were subjected to Wilcoxon analysis to compare the blood glucose levels before and after the intervention. The differences in MDA and SOD levels between groups were determined with one-way ANOVA followed by Duncan's new multiple range test. The level of statistical significance was set at p<0.05. Results: The intervention with Bilih fish flour resulted in a decrease in blood glucose levels. Intervention with Bilih fish flour with a dose of zinc of 0.54 mg lowered blood glucose as much as 38.95% and a dose of zinc of 0.27 mg lowered blood glucose as much as 32.45%, which was a significant decrease (p<0.05). The levels of MDA in rats that received intervention with Bilih were 9.87±2.88 μmol L1 for the D-P1 group and 11.88±10.5 μmol L1 for the D-P2 group, which were both lower compared to the control diabetic rats (D) (14.35±6.4 μmol L1). The levels of SOD in rats that received intervention with Bilih with the high zinc content were higher compared to the diabetic rats with standard feed but this increase was not significant (p>0.05). Conclusion: Bilih fish flour with a high zinc content lowered blood sugar levels but did not decrease the oxidative stress levels based on MDA and SOD levels in a diabetic rat model. MDA was not decreased and SOD was not increased significantly compared to diabetic controls.
