The effects of KSYS compound on the thermal stability of old mice hepatic DNA were studied in this experiment. The results were as follows: The melting temperature and hyperchromic effect of old mice hepatic DNA were obviously higher than those of young mice hepatic DNA; The melting temperature and hyperchromic effect of hepatic DNA from old mice fed KSYS compound were obviously lower than those from old mice without KSYS compound. The results showed that KSYS compound can improve ageing changes of old ...
