Abstract

Wound healing in hyperglycemia patients is still a challenge in the medical field. Bioactive compounds of binahong leaf extract can support the wound healing process. Nanoencapsulation of the extract can avoid oxidation and optimize drug delivery to target tissues. This study aimed to analyze the effect of nanochitosan encapsulated binahong extract ointment (NEBE/Oint) on the percentage of wound healing, angiogenesis, collagen density, and epithelial thickness in hyperglycemic rats. This study used 80 mg/kg streptozotocin-induced hyperglycemia rats injured in the back area. Rats were divided into P0 (0,9% NaCl), P1 (10% povidone-iodine ointment (PI/Oint)), P2 (10% NEBE/Oint), P3 (20% NEBE/Oint), P4 (30% NEBE/Oint). Phytochemical screening of binahong leaves extract showed positive results for flavonoids, alkaloids, saponins, and tannins. NEBE particle size was 169 nm with a size distribution of 0.2 and a zeta potential value of -40,2 mV. The results showed NEBE ointment had a significant effect when compared with negative control on wound healing hyperglycemic rats. The conclusion is that nanochitosan drug delivery has the potential as an alternative wound treatment. The novelty of this study is the use of nanochitosan to accelerate wound healing in hyperglycemic rats. The results of this study are expected to become a reference for new wound-healing methods in the medical field.

Abstract

Providing standard feed to support and improve the growth, productivity, health, and digestibility of livestock still requires feed additives, one of which is the natural feed additive spirulina flour. Spirulina flour was one of the natural feed additives chosen because it contained bioactive compounds, had no side effects on livestock, and substitute for antibiotics for livestock, so it could increase the growth, productivity, health, and digestibility of Peking ducks. The aim of this study was to analyze the effect of spirulina flour feed additive on Peking duck liver histomorphometry. This research used a Completely Randomized Design (CRD) with 5 types of spirulina flour concentration treatments (0%, 2.5%, 5%, 7.5%, and 10%) and 5 replications including 5 ducks in each replication. The treatment groups included P0, P1, P2, P3, and P4. Measurement variables included liver weight, hepatosomatic index, hepatocyte and central vein diameter, and sinusoid width. The data obtained were analyzed by the Analysis of Variance (ANOVA) test with a confidence level of 95%. The results showed that the addition of spirulina flour as a feed additive had no effect on liver weight, hepatosomatic index, hepatocyte diameter, central vein diameter, and sinusoid width. The conclusion of this research was that added spirulina flour (Spirulina sp.) feed additive potentially maintained the histomorphometry of the Peking duck liver organ.
