土豆法外敷快速消肿、散结266例分析

目的观察土豆片外敷注射部位肿胀、硬结的疗效。方法将我院266例注射部位肿胀、硬结患者随机分为两组,对照组139例采用硫酸镁外敷法治疗,试验组127例采用土豆片外敷治疗。结果试验组24小时、48小时及10天肌肉硬结治愈率分别为59.4%、89.1%、95.3%,明显高于对照组16.7%、43.3%及83.3%(P<0.05);试验组24小时皮下淤血治愈率为88.2%,显著高于对照组32.3%(P<0.05);试验组24小时、48小时及10天静脉炎治愈率分别为62.1%、75.9%、86.2%,显著高于对照组17.6%、41.2%及52.9%(P<0.05)。结论土豆片外敷注射部位对肌肉硬结、皮下淤血及静脉炎具有较高的治愈率,同时方法简便、安全性高。

水壶绿色除垢法

磁铁除垢法 在结有很多水垢的水壶中放入一块磁铁,烧水时会使壶内厚厚的水垢自行裂开脱落。 土豆除垢法 在结满水垢的壶中放几个土豆,煮上几个小时,壶内厚厚的水垢就会自行脱落,而壶体不会损坏。 苹果除垢法 在水壶中放满苹果,盖严壶盖。一周后取出苹果,壶内壁的水垢会变软。

利用土豆片上浮法探究pH对酶活性影响的实验创新设计

探究实验采用土豆片上浮法,在实验选材、反应场所、检测方式等方面都进行了创新,变定性实验为定量实验,使整个操作步骤更加简化规范,实验现象更加直观具体,实验结果更加快速精准。用土豆片上浮时间的倒数作为纵坐标表示酶的活性,用来构建酶活性受pH影响的数学模型,掌握探究最适pH的实验设计方法,继而帮助学生理解酶的催化活性需要适宜的pH,过酸、过碱会使酶变性失活,培养了学生的创新能力、科学探究能力,落实了生物学学科核心素养。

Effect of Soil Amendments on Soil Borne Pathogens of French Bean （Phaseolus vulgaris L,） in Organic Farming System in Manipur

The rationale behind the use of soil amendments by traditional marginal farmers against soil borne pathogen is an area of interest. The present work ascertain the effect of certain soil amendments against pre emergent and post emergent rot of French bean in the agro climatic condition of Manipur, Four soil amendments： cow dung （COD）, sawdust （SD） ＋ paddy husk （PH）, decomposed floating phytomat （DFP） was tried in field conditions in four different combinations. These have been often used by the traditional farmers. A locally available commonly cultivated pole type of French bean has been used for the study. Disease incidences in plots treated with these amendments were then compared with that of control plots where no amendments were made. The plots with a combined treatment of the soil amendments showed maximum seed germination and least post emergent rot against sclerotinia rot. But DFP showed effectiveness against rhizoctonia rot with maximum seed germination while saw dust showed maximum decrease in post emergent rot against rhizoctonia rot. The plots treated with organic soil amendments showed statistically significant positive effect against the pathogens as compared with untreated control plots.
