This study is to analyze the dynamic changes of inflammation and oxidative stress in mice infected with MRSA and to provide experimental basis for clinically formulating reasonable treatment plans. We established a model of MRSA infection in mice, detected the fluctuations in the concentration of proinflammatory cytokines and oxidative stress factors with time, and combined with the results of microscopic examination of tissue sections to explain the infection in vivo caused by MRSA. The results showed that on the 1st, 3rd, and 7th day of MRSA infection, the number of leukocytes and eosinophils decreased at first and then increased, monocytes increased continuously, and neutrophils and basophils decreased. At the same time, the levels of proinflammatory cytokines IL-1β, IL-6, and TNF-α increased. The concentration of glutathione peroxide decreased, and the oxidative metabolites increased. Tissue sections also showed that inflammation and oxidative stress occurred in mice. It is obvious that MRSA infection can lead to significant inflammation and oxidative stress. Therefore, while treating MRSA infection, attention should be paid to the levels of inflammation and oxidative stress in different periods to achieve better treatment effects. |
