Abstract:
Objective To observe the clinical effect of Sarcandra glabra extracts against oxida-tive damage. Methods 46 patients diagnosed as nasopharyngeal careinoma stage Ⅲ and Ⅳ a were ran-domly divided into control group (n=25) and study group (n=21). All patients underwent combined chemoradiotherapy treatment. Besides, the patients in study group were given Sarcandra glabra 20 g/d orally. The total activity of superoxide dismutase (SOD) and plasma eontent of malonaldehyde (MDA) were measured before and after treatment. The tumor regression and aeute chemoradiotherapy side reaction were observed after treatment. Results All patients fulfilled the whole range treatment, After treatment, the total plasma SOD activity decreased and plasma MDA level was elevated in con-trol group, while both SOD aetivity and MDA level were reduced in study group (P<0. 05). When the therapy ended, the SOD of study group was higher and MDA was lower than that of control group (P<0.05). There was no difference in tumor local control rate after radiotherapy between two groups (P>0.05). The incidence rate and severity of acute chemoradiotherapy side reaction were slighter in study group than those in control group (P<0. 05). Conclusion Sarcandra glabra extracts exerts obvious inhibitory effect on oxidative damage. Combined with chemoradiotherapy, Sarcandra glabra contributes to the tumor regression of patients with stage Ⅲ and Ⅳa nasopharyngeal carcinoma and at-tenuation of chemoradiotherapy side reaction.
