Broilers were randomly allotted by BW to 1 of 6 replicate cages （29 chicks per cage） for each of 8 treatments in a randomized block design involving one factorial arrangement of treatments. Dietary treatments included the basal diet （including corn, soybean, rapeseed, cottonseed meal） added with 100 mg/kg antibiotic, 0%, 0.05%, 0.1%, 0.15%, 0.2%, 0.25% or 0.3%. The experiment last 42 d and divided into the starter period （1-21 d） and the finisher period （22-42 d）. The results showed that there were significant differences in broiler body weight （BW） （P〈0.001）, average daily feed intake （ADFI） （P=0.033）, relative length of the duodenum （P〈0.001）, jejunum （P=0.008）, ileum （P〈0.001） and the populations of lactobacillus （P〈0.001） and coliform （P〈0.001） in the rectum between the probiotics treatments and the control treatment only in the starter period of the trails. No significant differences were observed in intestinal morphology parameters in two periods of the experiment. Our results indicated that the probiotic was able to improve the performance of broiler chickens, and it was better in the starter period to be used than in the finisher period.展开更多

Methods: Thirty-four patients were confirmed diagnosis with cancer by pathologic results. All patients were given 6MV X-ray for radiotherapy, Dt 66-70 Gy/33-35 f/6-7 w, concurrently administrated nedaplatin (30 mg/m2) once a week (6 times). Results: A total 34 patients were enrolled, of whom 33 patients were available for objective response, 1 patient of esophageal cancer quit for allergic reaction. The response rate (RR) of nedaplatin-contained therapy for nasopharyngeal carcinoma and esophageal carcinoma were 90.0% and 76.9%, respectively. The major toxic reaction was bone marrow suppression observed in 25 patients (73.5%), in which grade III aleukocytosis was observed in 3 patients (8.8%), grade III + IV thrombocytopenia in 3 patients (8.8%). And 6 patients (17.6%) showed gastrointestinal tract reaction. There were 4 patients with radiation esophagitis in the 13 patients with esophageal carcinoma. Conclusion: Nedaplatin can increase the therapeutic effect of radiation. Its incidence rate of bone marrow suppression is high, but the gastrointestinal tract reaction and renal toxicity is low and mild.展开更多
