The effect of red fruit oil (Pandanus conoideus Lamk.) emulgel on angiogenesis and collagen density in incisive wound healing in mice (Mus musculus)

Pandanus conoideus Lamk. or commonly known as red fruit oil (RFO) can be used to accelerate wound healing because it contains tocopherols, carotenoids, oleic acid, linoleic acid, and linolenic acid. The RFO in this study was formulated in the form of an emulgel because it has the most convenient and effective drug delivery system. The aims of this study were to determine the activity of RFO emulgel on increasing the amount of angiogenesis and collagen density in incised wound healing and to determine the optimal dose of RFO emulgel to increase the amount of angiogenesis and collagen density in incised wound healing. This was a true experimental study with a posttest only control group design that included five treatment groups: a positive control group (10% povidone-iodine), a negative control (gel base), and three groups that varied the concentration of RFO emulgel used at 5%, 10%, and 15%. Parameters observed were the amount of angiogenesis using Image Raster software and the percentage of areas of collagen density using ImageJ software. The data were analyzed using a one-way ANOVA test and continued with the least significant difference test. The results of this study showed that RFO emulgel was able to increase the amount of angiogenesis and collagen density in the wound healing process with P = 0.000. An increase in the amount of angiogenesis and collagen density occurred in mice treated with RFO compared to the positive and negative control groups. It can be concluded that RFO emulgel has activity toward increasing the amount of angiogenesis and collagen density in the wound healing of mice incisions. The optimal dose concentration of RFO emulgel for increasing the amount of angiogenesis and collagen density in incision wound healing was shown in RFO emulgel with a concentration of 15%.
