The serum parameters associated with the symptoms of metabolic syndrome, including glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), triglycerides, cholesterol, low-density lipoprotein (LDL), glucose and lactate dehydrogenase (LDH) (except high-density lipoprotein (HDL) and insulin), were significantly elevated in the OVX group, the OVX + PRP group and the OVX + PPP group, as compared to the sham group. Here, INS is linked to metabolic syndrome.
