CFDT decoction improved mitochondrial function in PCOS rats model. Rats were treated with CFDT decoction (15.0 g/kg.d) and metformin (50 mg/kg) followed by feeding with HFD and intraperitoneal injection with of letrozole (1 ml/kg/d) for 21 days. (A) Electron microscope pictures (10,000×; 20,000×; 40 000×) of the ovary in PCOS rats, the scale bars represents a length of 2 μm, 1 μm, and 500 nm on histology respectively. Abnormal mitochondrial (paired yellow arrow) morphology showed mitochondrial membrane rupture or swellings, and normal mitochondrial (single yellow arrow) morphology type showed smooth mitochondrial membrane and distinct inner carinulae and percentage of damaged mitochondria; (B) The MMP (ratio of red/green), the opening of mPTP (%), the mitochondrial ROS, the mtDNA damage (ratio of long/short fragments), the mitochondrial RCR, mitochondrial oxygen consumption rate; (C) The mitochondrial respiratory chain complex enzymes (I, II, III, IV, and V) and ATP were recorded above. Data are shown as mean ± SD. *p < 0.05 versus control group, # p < 0.05 versus PCOS group, △ p < 0.05 versus PCOS+ CFDT group. (n=6).
