Objective: Kefir are natural probiotic compounds with anti-inflammatory properties, which were tested in experimental burn injury. Kefir gels were prepared from an extract of continuously cultured kefir in Man, Rogosa and Sharpe Broth medium for 48 and 96 h. Their extracts were used for evaluation of antibacterial effect against Pseudomonas aeruginosa in standard sample (ATCC 27853) and samples taken from patients with burns. The antibacterial effect of different kefir extract was assessment of minimum inhibitory concentration and minimum bactericidal concentration. The density of bacteria and percentage of organic acids (lactic and acetic acids) were also determined.
Materials and Methods: Similar burn injuries were made on dorsal skin surface of 40 rats. The rats were divided into 5 groups of 8 rats each. The base gel, silver sulfadiazine ointment, kefir 48 h gel, kefir 96 h gel were applied twice daily. Burn wound area was measured at baseline, 1 and 2 weeks.
Results: Results indicated that by increasing the time of fermentation, concentration of lactic and acetic acid increased in orders of: Kefir 48 h < kefir 96 h, the end of the 2nd week the percentage of wound size were lowest in order of kefir 96 h gel < kefir grains 48 h gel < silver sulfadiazine 1% < untreated and based gel groups.
Conclusion: In conclusion, the kefir gel therapy was an effective therapeutic approach to improve outcomes after severe burn when compared with conventional silver sulfadiazine treatment.
