Objective: To investigate the effect of Wuzi Yanzong Pill (WZYZP) on mitochondrial DNA (mtDNA) deletion and respiratory chain enzyme complex (RCZC) in peripheral blood leukocyte of aged male with Kidney Deficiency Syndrome (KDS).
Methods: Single-blinded study was conducted in 38 aged male with KDS, who were randomly divided into 2 groups treated with WZYZP and placebo respectively for 3 months. Levels of mtDNA deletion and RCZC were determined by polymerase chain reaction (PCR) and enzyme kinetics technique respectively.
Results: WZYZP could reduce the mtDNA deletion and raise the activity of mitochondrial RCZC I, IV in peripheral blood leukocyte of aged male with KDS (P < 0.05, P < 0.01).
Conclusion: WZYZP has protective effect on mtDNA from oxidative damage in leukocyte of aged male with KDS.
