Effect of analog rice’s fiber on skeletal muscles GLUT4 expression in diabetic rats Background: Disruption of glucose transportation in skeletal muscle through GLUT4 becomes a problem in diabetes. Analog rice that had been modified by adding dietary fiber could improve the expression of GLUT4.Objective: This study aims to know the effect of dietary fiber toward GLUT4 expression and to know the dietary fiber percentage in analog rice.Method: The research type is true experimental with post-test only group design. The samples consist of 24 male Wistar rats that are group into 4 groups (n=6 each group). Three groups were induced by giving a high-fat diet for 40 days and streptozotocin (STZ) 35 mg/kg BW was given at 33th day and one group was not induced. After the blood glucose level exceeded 135 mg/dl, the treatment was given. After 3 weeks, the rats were terminated and quadriceps femoris muscle tissue was taken for immunohistochemistry examination using rat GLUT4 polyclonal antibody. GLUT4 expression was quantified using an immunoreactive score (IRS-GLUT4). The data were analyzed using the Kruskal-Wallis test and Spearman test.Results: Statistical analyses showed that there were significant differences between groups with a moderate positive correlation (correlation coefficient=0,651; p=0,003).Conclusion: Dietary fiber in analog rice could improve skeletal muscle GLUT4 expression in Wistar rat diabetic model.

Early diagnosis of pediatric appendicitis is still difficult to make and 30-40% of cases do not show typical classic symptoms. The negative appendectomy rate and the risk of perforation reach 20% so that new, easy, inexpensive and accurate additional examination is needed. This study aimed to compare platelet distribution width (PDW) and mean platelet volume (MPV) values of appendicitis and control patients. This study is retrospective case control study. Differences in MPV and PDW levels in patients with appendicitis and controls were analyzed with a t-test and determination of sensitivity, specificity and accuracy of the two markers in appendicitis diagnosis were performed by ROC analysis The mean MPV appendicitis was significantly lower (p <0.05) compared to controls (8.3 ± 1.9; 9.2 ± 1.5) while PDW of appendicitis patients did not differ significantly from controls (10.4 ± 1, 4, 10.7 ± 2.4; p> 0.05). AUC MPV as a diagnostic tool for appendicitis 0.619 with a normal limit of 6.6 fl has a sensitivity of 90% and specificity of 30%. MPV can be used for the diagnosis of appendicitis with a normal limit of 6.6 fl having a sensitivity of 90% and specificity of 30%. There was no significant difference between PDW of appendicitis patients with controls. There was no significant difference between MPV levels of patients with simple appendicitis and complications.  Keywords: Appendicitis, MPV, PDW, Platelet
