ABSTRACT
The inheritance of the white-flower and its influence to related characters in eggplant were studied with the white-flowered mutant of XIANLVQIE and its maternal bred. Result showed that the flower color was attributed to a couple of complete dominance genes. Purple color flower "Col" was dominant to the white "col". Compared with the purple-flowered strain, the white-flowered strain not only grew more blooming, but also had more stamens in one flower, less pollens in one anther and less seeds in one fruit. In the meanwhile, in white-flowered eggplants, microspore and fruit was bigger, and yield was higher than purple-flowered. The white-flowered strain could be used as a variety and the white-flowered character could be used as a marker to appraise purity of hybrid in eggplant.

<p><b>OBJECTIVE</b>To evaluate the efficacy and toxicity of combination chemotherapy using gemcitabine plus cisplatin for recurrent and/or metastastic head and neck cancer patients.</p><p><b>METHODS</b>Fifty-two patients with recurrent or metastatic head and neck cancer were treated by gemcitabine 1000 mg/m(2) on D1, 8 and cisplatin 25 mg/m(2) on D1 approximately 3 every 21 days as one cycle.</p><p><b>RESULTS</b>Of 52 assessable patients, 3 (5.8%) showed complete response and 19 (36.5%) partial response with an overall response rate of 42.3% (22/52). Median time to progression was 5.0 months, and 1-year survival was 43.4% with a median survival time of 9.9 months. Of 32 previously treated patients by cisplatin-containing regimen, 2 patients (6.3%) gave complete response and 11 (34.4%) partial response with an overall response rate of 40.6% (13/32). Median time to progression was 3.4 months, and 1-year survival was 29.2% with a median survival time of 8.3 months. Toxicity mainly included grade 1/2 myleosuppression, rash and nausea/vomiting.</p><p><b>CONCLUSION</b>Gemcitabine plus cisplatin chemotherapy is safe and effective for patients with recurrent and/or metastastic head and neck cancer.</p>
