中药“口康”含漱液体外抑菌试验和毒性试验研究

OBJECTIVE: To study the antibacterial activity of Chinese medicine kou-Kang mouthwash and its acute toxicity, and provide the basis of experiment and therapy for infectious diseases of the oral cavity. METHODS: Minimal inhibitory concentrations (MIC) of kou-Kang mouthwash were determined by the agar dilution method, and the acute toxicity was done. RESULTS: The range of MIC kou-Kang mouthwash against 27 Gram negative bacterial were 0.03-1.0 g.ml-1. MIC50 was 0.125 g.ml-1 and MIC90 was 0.125-0.5 g.ml-1. The range of MIC kou-Kang mouthwash against 21 Gram positive bacterial was 0.008-0.5 g.ml-1. The range of MIC50 and MIC90 were 0.015-0.125 g.ml-1 and 0.015-0.5 g.ml-1, respectively. The value of MIC was 0.015 g.ml-1 against candidia albicans. The acute toxic test indicated that the maximum tolerance dose was 417.6 g.kg-1 and 210 times as much as the clinical dose a day. No death of animals or toxicity and side-effect occurred in the test. CONCLUSION: Kou-Kang mouthwash shows a potent antibacterial activity against various pathogens of the oral cavity. Its antibiotic activity against Gram positive bacteria was 2-8 times stronger than that against Gram negative bacteria. It has low toxicity and can be used in clinical application.

东莨菪碱诱发染色体畸变的剂量效应

东茛菪碱五个剂量(1、2、5、10、20μg/ml作用于12名健康成人外周血淋巴细胞培养液诱发染色体畸变,并设空白对照组(生理盐水)。染色体畸变率分别为3.±0.5,9.6±1.1,11.7±1.1,13.6±2.3,18.0±3.0和17.5±2.0％;细胞畸变率为3.1±0.6,9.2±0.6,10.0±0.8,10.8±1.5,11.6±1.8和12.2±14.％。各剂量组与对照组比较差异高度显著(P<0.01)。方差分析,各剂量组间变异的差异高度显著(P<0.01)。相关系数和回归系数也非常显著(P<0.01)。结果表明,东莨菪碱剂量与染色体畸变率和细胞畸变率有线性关系。

循证护理学在实践中的应用

循证护理的核心思想是任何护理决策都要建立在临床客观证据的基础上。护理过程中应进一步开展临床试验研究，以提供更好的护理依据。对临床护理工作中存在的同一问题有不同研究结果的情况，要用系统评价的方法进行分析，得出综合可靠的结论。作举例说明循证护理的实施方法。
