The Effect of Topical Toman Fish (Channa micropeltes) Extract on Macrophages and Lymphocytes in Diabetes Mellitus Wound Healing

Abstract

Oral administration of Toman fish extract is proven to accelerate wound healing in rat model of Diabetes Mellitus. Toman fish extract contains albumin which may elevate antioxidant level and reduce inflammation. These changes will later enhance cell proliferation and inflammatory cell activity in wound healing process. This study was aimed to determine the topical application effect of 20% toman fish extract on macrophages and lymphocytes in Diabetes Mellitus wound healing. It was an experimental research using post-test only with control group design. This study was performed on 36 diabetic male wistar rats which was comprised of negative control group without given any treatment, 20% Toman fish extract ointment group and 10% Haruan fish (Channa striata) extract ointment group. Rats were sacrificed on day 4, 8, and 14 to investigate wounded area with biopsy technique which later obtained histological preparation using Haematoxylin-Eosin staining. The preparation was then observed using microscope to count macrophages and lymphocytes number. One-Way ANOVA test demonstrated a significant difference in macrophage number on day 4 (p=0.002), day 8 (p=0.000), day 14 (p=0.000). The result of the test also indicated a significant difference in lymphocyte number on day 4 (p=0.001), day 8 (p=0.001), and day 14 (p=0.001). Furthermore, Post Hoc LSD test resulted in a significant difference (p<0.05) of macrophage and lymphocyte in day four, eight, and fourteen among all treatment groups. Toman fish extract ointment at 20% concentration for topical application may raise the number of macrophage and lymphocyte than those of negative control and 10% haruan fish extract ointment on day 4 and 8 with gradual decrease on day 14.
