This study found that diabetes has detrimental effects on lung tissue, and swimming exercise can alleviate these effects. Swimming exercise can reduce diabetic-related pathologies in mouse lungs by regulating apoptosis and inflammatory response.
BackgroundDespite the vulnerability of pulmonary tissue to diabetic conditions, there are few reports related to the detrimental effects of hyperglycemia and therapeutic modalities on lung parenchyma. Here, the apoptotic changes were monitored in the diabetic pulmonary tissue of mice (DM1) subjected to a four-week swimming plan.MethodsThe mice were randomly allocated into Control; Control + Swimming (S); Diabetic group (D); and Diabetic + Swimming (D + S) groups (each in 8 mice). In the D and D + S groups, mice received intraperitoneally 50 mg/kg of streptozotocin (STZ). After 14 days, swimming exercise was done for four weeks. The expression of il-1 beta, bcl-2, bax, and caspase-3 was investigated using real-time PCR analysis. A histological examination was performed using H&E staining.ResultsDM1 significantly upregulated il-1 beta, bax, and caspase-3, and down-regulated bcl-2 compared to the non-diabetic mice (p < 0.05). We noted that swimming exercises reversed the expression pattern of all genes in the diabetic mice and closed to basal levels (p < 0.05). Data indicated that swimming exercise could diminish emphysematous changes, and interstitial pneumonitis induced by STZ. Along with these changes, swimming exercise had protective effects to reduce the thickness of the inter-alveolar septum and mean alveolar area in diabetic mice.ConclusionThese data demonstrated that swimming exercises could decrease DM1-related pathologies in mouse lungs by regulating apoptosis and inflammatory response.
