Abstract

One problem for postoperative patients is tissue recovery takes a long time due to the occurrence of blood clotting disorders and immune system. Snakehead fish was known to contain bioactive ingredients that can potentially speed up the process of tissue repair as a result of injuries. Snakehead fish meat contains a lot of minerals, albumin, and amino acids needed for tissue protein synthesis and increases the antioxidant glutathione. This study was conducted to test the extraction of snakehead fish flesh against skin tissue wound healing in Wistar rats. The study was conducted with a completely randomized design consisting of three treatments with 6 replication, which include (P0) a negative control (without treatment madecassol and snakehead fish meat extract), (P1) madecassol commercial drug treatment, and (P2) treatment of snakehead fish meat extract. Each material was injected intramuscularly in Wistar rats at a dose of  9 ml/kg bb for 7 days. Data analysis uses Anova followed by test Honestly Significant Difference (HSD) with a significance of 95%. Treatment of snakehead meat extract with a dose of 9 ml/kg bb a significant effect on skin tissue repair after injury, better than treatment with madecassol and control with the average value of extensive tissue remaining after recovering from the condition of the wound by 0.2 cm2; 0.33 cm2; and 0.4 cm2, respectively. Snakehead fish meat extract with a dose of 9 ml/kg bb injected intramuscularly can accelerate the recovery of tissue in the skin after the wound in Wistar rats.

Abstract

The public demands for the refill drinking water increases causing the development of refill drinking water industries. However, the problems occurred is no standard method to process drinking water with sterile and lack of government oversight. These cases give rise to sanitation which is the formation of bacteria pathogen forming biofilms in refill drinking water system. One of the bacteria pathogens is Salmonella. Salmonella in refill drinking water can cause diarrhea, because it can produce cytotoxin and enterotoxin. Bacteriophages are viruses that infect bacteria. This study aims to find natural isolates of bacteriophage from biofilm samples to infect Salmonella spp. in refill drinking water system. The isolates obtained is then characterized by biochemical test including Gram stain, a test Kligler Iron Agar (KIA) and api assay 20 E. The positive Salmonella spp. isolates are in the second dilution refill drinking water depot. The isolation of bacteriophage from biofilm is conducted with bacteriophages amplification and bacteriophage filtrate. The Infection test is performed by using Salmonella enterica, Salmonella 7A1 from Teluk Ambon and Salmonella spp. from refill drinking water depot. Platting is performed on serial dilutions of 10-2 to 10-10phage dilution. Positive result is characterized by the formation of plaque which is in source water samples, water product and drinking water depot. The number of plaques formed is calculated by Plaque Forming Units (PFU/mL) to determine quantification or calculation phages.
