Effects of either ALC or OXF on cardiac function in the STZ-diabetic rats.

All values are expressed as means ± SE. Pes, LV end-systolic pressure (mmHg); Ped, LV end-diastolic pressure (mmHg); dP/dtmax (mmHg s−1); dP/dtmin (mmHg s−1); τ, time constant of LV isovolumic pressure decay (ms); LV, left ventricle. NC, normal controls; NC+ALC, NC treated with ALC; NC+OXF, NC treated with OXF; DM, STZ-diabetic rats; DM+ALC, DM treated with ALC; DM+OXF, DM treated with OXF; ALC, acetyl-L-carnitine; OXF, oxfenicine.†Statistical difference (P‡Statistical difference (P所有数值均以平均值±标准误（standard error, SE）表示。其中：Pes为左心室收缩末期压力（LV end-systolic pressure，单位：mmHg）；Ped为左心室舒张末期压力（LV end-diastolic pressure，单位：mmHg）；dP/dtmax的单位为mmHg·s⁻¹；dP/dtmin的单位为mmHg·s⁻¹；τ为左心室等容压力衰减时间常数（单位：ms）；LV为左心室（left ventricle）。NC为正常对照（normal controls）；NC+ALC为经乙酰-L-肉碱（acetyl-L-carnitine, ALC）处理的正常对照组；NC+OXF为经氧芬扎辛（oxfenicine, OXF）处理的正常对照组；DM为链脲佐菌素诱导糖尿病大鼠（STZ-diabetic rats）；DM+ALC为经ALC处理的糖尿病模型组；DM+OXF为经OXF处理的糖尿病模型组；ALC即乙酰-L-肉碱；OXF即氧芬扎辛。†表示统计学差异（P‡表示统计学差异（P
