Abstract

Studies were undertaken to evaluate the effects of aqueous extract of Lycium barbarum on serum creatine kinase (CK) and creatine kinase mass (CK-MB) activities in exhausted swimming rats. Forty Wistar rats were randomly assigned to five groups: normal control group (NC), exhausted swimming model control group (MC), low dose of LBE administration group (I), middle dose of LBE administration groups (II) and high dose of LBE administration groups (III). From the 31st day, except for normal control rats, all rats received exhausted swimming exercise for 1 week. Results showed that LBE pre-treatment can reduce serum CK, CK-MB activities and myocardium injury in exhausted swimming rats.

Key words: Creatine kinase, creatine kinase mass, exhausted swimming.
