[Influence of radix Astragali on noise-caused changes in hepatic glycogen content in the rat]

It has been found that in rats exposed to a noise of 2kHz (mai frequency) and 103 dB(A) (potency) for 60 minutes, the hepatic glycogen content (HGC) is significantly higher than that of the control group unexposed to the noise (P less than 0.05), whereas in those treated with a prior ip Radix Astragali plus noise the HGC appears apparently lower than that of the noise group (P less than 0.05), very close to the control group (P greater than 0.2). This indicates that Radix Astragali might have some antinoise effect.
