METH treatment consisted of administering 5 mg\/ kg per day of METH. ET was conducted five days per week on a treadmill at 0\u00b0 inclinations. Each session lasted 30 min (3 m\/min for the first 5 min, 5 m\/min for the next 5 min, and 8 m\/min for the remaining 20 min). The levels of serum CK and LDH, along with the expression levels of caspase-1, interleukin-1 beta (IL-1\u03b2), and interleukin-18 (IL-18) in myocardial tissue were examined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>METH exposure increased the levels of serum CK and LDH and the expression of caspase-1, IL-1\u03b2, and IL-18 (P\u2009\u2264\u20090.05). Withdrawal of METH led to a reduction in the expression of these factors (p\u2009\u2264\u20090.05). Moreover, combining METH withdrawal with six weeks of ET further decreased the levels of serum CK and LDH and the expression of caspase-1, IL-1\u03b2, and IL-18 (p\u2009\u2264\u20090.05).<\/jats:p>\n
