Medical plasma gas improves corneal burn ulcers in rabbits

Gas plasma helps wounds heal in veterinary medicine, which is why gas medical plasma is used to study a wide range of animal models with different unsolved medical problems. The purpose of this study was to assess the experimental wound healing of corneal burns in rabbits exposed to corona plasma radiation. This investigation was conducted on 10 adult male white New Zealand rabbits of varying weights and ages. The Department of Animal Breeding and Laboratory of the Pasteur Institute of Iran prepared the rabbits, and the protocol for this study was conducted in compliance with the International Committees for the Protection of Laboratory Animal Rights-approved ethical norms. To induce anesthesia, intramuscular injections of 10% ketamine at 40 mg per kg body weight and 2% xylazine at 10 mg per kg body weight were given. After instilling 2 drops of 0.5% tetracaine into the right eye of each rabbit under general anesthesia, a 6 mm diameter circular filter paper containing 30 l of normal saline was put in the middle of the cornea for 60 seconds. After removing the filter paper, 2 mL of standard sterile saline was used to cleanse the eyes. They were separated into two groups of five. The second group received daily treatment for twenty days. At the end of 20 days, anesthesia was administered and ocular excision was performed on the animals. Pathological tests show that plasma corona radiation seems to help heal corneal burns in the group that was treated with it.
