It is well known that the immune system has been actively involved in the regeneration and healing processes of post burn wounds. However, unanswered questions remain concerning the role of humoral immunity in the healing mechanisms and development of burn wound complications. We have developed an experimental model of chemical esophageal burn (CEB) which corresponds to esophageal burn in 1-8 years old children. We studied the features of humoral immunity upon CEB in rats. A decrease in IgG levels and an increase in levels of medium- and low- molecular circulating immune complexes (CIC) on the first day of esophageal burns were observed. On the 21st day of burn, we observed an increase in the IgG concentration and a tendency to accumulation of medium- and low-molecular CIC. The studied indicators can be used to differentiate CEB development and create a timeline of burn wounds.
