Effects of Spascupreel versus hyoscine butylbromide for gastrointestinal cramps in children

BACKGROUND: Gastrointestinal spasms and cramps are common in children as well as in adults. Alternative medical practices such as chiropractice and homeopathy are becoming increasingly popular in Europe and the USA. The effectiveness and tolerability of the homeopathic preparation Spascupreel was compared with that of hyoscine butylbromide treatment in children <12 years of age. METHODS: An observational cohort study in 204 children <12 years was conducted over a 1 week treatment period. The efficacy of the respective therapies were evaluated on the effect on severity of spasms and clinical symptoms (pain/cramps, sleep disturbances, distress, eating or drinking difficulties and frequent crying). Compliance was evaluated on a four-point scale from 'very good' to 'low'. Evaluation was done by the practitioner based on information given by the patient or minder. RESULTS: The analysis showed comparative improvements with the homeopathic preparation and hyoscine butylbromide therapy on severity of spasms, pain/cramps, sleep disturbances, eating or drinking difficulties, and frequent crying, all as evaluated by the practitioner. Both treatments were very well tolerated. CONCLUSIONS: For patients opting for a homeopathic therapy, Spascupreel seems to be an effective and well tolerated alternative to conventional therapies in children suffering from gastrointestinal spasms.     

人精子染色体改良技术及其应用

课题研究提供了改良的人精子染色体直接制备，Ｇ显带核分析技术。在对８０例对象的人精子染色体直接制备，Ｇ显带核型分析中，成功率为６２．５％，较Ｔｅｍｐｌａｄｏ方法的成功率（５８．１％）进一步提高。通过对正常人，不育，流产对象的男性精子染色体研究，发现精子染色体数目和结构畸变率分别为：正常人２．３％和０％，不育１４．０％和４．８％，流产组４．５％和２．４％，不育和流产组的畸变率较正常人增加。在对５例染色     

An investigation into the information obtained by patients undergoing gastroscopy investigations

? The benefits of informing patients before undergoing surgery or other investigative procedures are clearly demonstrated in the literature. ? This study aimed to determine the amount and type of information given to patients before, during and after undergoing gastroscopy investigations. ? A survey approach incorporating structured interviews and structured observation was utilized. ? There were statistically significant differences between the information acquired by younger and older patients prior to, but not during or after, the procedure. ? Nurses appear to be the most important source of information for older patients while the information leaflet was perceived as the most important source of information for younger patients.

T2毒素在灌流大鼠肠肝中的首过效应和代谢动力学

建立并用大鼠在体肠-肝灌流标本研究了T2毒素在大鼠肠肝中的首过效应和代谢转化动力学,T2毒素在大鼠肠肝中的主要代谢产物是HT2,3′-OHHT2和其葡萄糖醛酸结合物,T2毒素具有显著的肠肝首过效应,当毒素(42μg·ml~(-1))由上肠系膜动脉恒速单次灌流(8 ml·min~(-1))肠-肝标本时,穗态肝、肠抽提率分别为0.978和0.454,总有效清除率为7.91 ml·min~(-1),T2毒素在循环灌流大鼠肠-肝标本中的消除半衰期为6.5min,主要代谢产物HT2,3′-OHHT2的生成半衰期分别为8.5和38.5 min,结果表明,T2毒素经消化道中毒后,在肠和肝的首过代谢下能很快地转化为产物,因此,毒素在体内的毒效作用主要由其代谢产物表现出来。
