Resistance Imparted by Traditional Chinese Medicines to the Acute Change of Glutamic Pyruvic Transaminase, Alkaline Phosphatase and Creatine Kinase Activities in Rat Blood Caused by Noise

Abstract

The activities of serum glutamic pyruvic transaminase (GPT), alkaline phosphatase (ALP) and creatine kinase (CK) in rats injected or not with the Chinese medicines, Astragali, Rhodiolae and Ligusticum, were determined after noise exposure. Noise at 95 and 105 dB significantly increased the activities of GPT, ALP and CK, and showed a dependence on the exposure time. The injection of each medicine significantly suppressed the increased enzyme activities by 95 and 105 dB noise.
