Abstract: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 glucogen content(HGC) is significantly higher than that of the control group unexposed to the noise (P<0.05), whereas in those treated with a prior ip Radix Astraga]i plus noise the HGC appears apparently lower than that of the noise group (P<0.05), very close to the control group (P>0.2). This indicates that Radix Astragali might have some antinoise effect.
