磁处理水对抗癌药物的解毒作用

我们的实验发现，磁处理水对环磷酰胺等五种抗癌药物的毒性具有不同程度的缓解作用，能增加小鼠的存活率，能降低药物引起的白细胞减少。对目前癌化疗中使用率最高的环磷酰胺，其作用最明显。     

青、老年大鼠在Morris水迷宫中的学习记忆行为

本实验观察了22～24月龄老年大鼠和5～6月龄青年大鼠在Morris水迷宫中的学习记忆行为,并用定量分析方法比较两组动物在定位航行及空间搜索试验中的学习记忆,结果表明老年大鼠的寻找平台潜伏期明显延长,而其跨平台次数及在平台象限的游泳路线长度并未减少.提示24月龄老年大鼠获取学习记忆的能力受损伤而保持记忆的能力维持正常,这可能与二种功能衰老的不同速度及不同神经基础有关.     

Effect of Locus Coeruleus Stimulation on Ocular Hypertension and Pathology of Pulmonary Surfactant during Chronic Emotional Stress

In chronic experiments on rabbits and rats, parameters of eye homeostasis (intraocular pressure and ocular hydrodynamics) and lungs (water balance and surface-active properties of surfactant) were studied during electrical stimulation of the locus coeruleus against the background of chronic stress induced in rabbits by repeated electrical stimulation of the ventromedial nucleus and in rats by daily immobilization on a platform. Stimulation of the locus coeruleus eliminated ocular hypertension of hypothalamic origin and stress-induced disturbances in surface activity, blood volume, and water balance in the lungs.     

Stabilization of Misoprostol with Hydroxypropyl Methylcellulose (HPMC) Against Degradation by Water

The stability of misoprostol oil is significantly improved in a hydroxypropyl methylcellulose (HPMC) dispersion (1:100). In order to assess the effect of water on misoprostol stability, the rate of misoprostol degradation was investigated in the misoprostol/HPMC dispersion at 55°C, along with the water sorption isotherm, under seven different relative humidity (RH) conditions ranging from 0 to 81%. The results indicated that the first-order rate constants of misoprostol degradation increased in a concave-up fashion as the water content of the dispersion increased. Below 30% relative humidity (2% water), the first-order rate constants of misoprostol degradation were found to be minimum. The results of the stability study were interpreted in terms of the changing structure of HPMC as it related to the mobility of water and misoprostol within the HPMC dispersion.     

临沂市改水效果及水源卫生防护状况调查

目的 了解临沂市改水效果及水源的卫生防护状况。方法 对临沂市改水前后水源的卫生防护状况进行了调查,并对自来水水质进行了监测。结果 与改水前比较,水源的卫生防护状况有很大改善;改水后水源水、出厂水、末梢水水质合格率分别为58．33％、67．80％、51．85％。均比改水前明显提高（P＜0．05）。改水后水质的主要超标项目为浑浊度,游度余氯、菌落总数和大肠菌群。结论 改水质自来水水质及水源及的卫生防护状况明显改善,水质主要受生活性污染,应加强对水源的卫生防护。     

吗啡成瘾对大鼠及小鼠学习与记忆能力影响的实验研究

目的 研究吗啡成瘾对大鼠及小鼠学习与记忆能力的影响。方法 将２４只ＳＤ大鼠昆明小鼠分别随机分成３组;即吗啡成瘾组、吗啡成瘾后戒断组和对照组。然后分组对动物进行Ｍorris水迷宫训练。结果（1）在Morris水迷宫掩蔽平台次训练中,吗啡成瘾组动物（大鼠和小鼠）的逃避潜伏期对与对照组及吗啡戒断组动物相比,均明显延长（P＜0．01）;（2）对照组动物的逃避潜伏期最短;（3）在Morris水迷宫可见平台学习中,无论是大鼠还是小鼠,三组动物逃避潜伏期均随着学习训练逐渐缩短,无明显组间差别（P＞0．05）。结论 吗啡成瘾可明显损害动物的学习记忆能力。

UV-Cured PDMS for Oil Removal from Wastewater

The removal of oil from water is a worldwide challenge that must be faced to avoid irreversible marine habitat destruction. A novel fast and simple technique to obtain polydimethylsiloxane (PDMS) membranes is developed using the photopolymerization technique. The high reactivity of the acrylated PDMS formulation toward photo-induced free radical polymerization is assessed via the differential scanning photo-calorimetry (photo-DSC) technique. Two different membranes dense or porous are developed and investigated. Porous membranes, having 100–200 µm as pore size, are obtained using a low-cost environmentally friendly sodium chloride template. Thanks to the hydrophobic/oleophilic intrinsic characteristic of PDMS, the UV-cured membranes can selectively remove dodecane, selected as the target oil, from water. The dodecane sorption capability of both membranes is investigated and compared. Moreover, the membranes can be easily reused since the adsorbed oil can be recovered by simply compressing the membrane. Those PDMS sorbents show high mechanical stability after five adsorption/desorption cycles.
