[Effects of some Chinese herbal medicine and green tea antagonizing mutagenesis caused by cigarette tar].
Anti-mutagenic effects of some Chinese herbal medicine and green tea antagonizing cigarette tar was studied with unscheduled DNA synthesis (UDS) test in human peripheral lymphocytes in order to exploit the better use of Chinese herbal resources. Results showed that Scutellaria barbata, Hedyotis diffusa wildi, Xihuangwan, green tea and tea polyphenol all had anti-mutagenic effects, to some extent. And, 125 g/L of Scutellaria barbata, 125 g/L Hedyotis diffusa wildi, 325 g/L Xihuangwan, 78 g/L green tea and 25 g/L tea polyphenol could inhibit obviously the damage to DNA in lymphocytes caused by the total particle material (TPM) extracted from cigarette tar. If the Chinese herbal medicine and green tea were injected into cigarettes beforehand, extracted TPM (containing herbal medicine and green tea) also could protect DNA in lymphocytes from damage caused by cigarette tar, to even greater extent. This result is basically consistent with other anti-mutagenesis tests.
