用stiger描述的大鼠模型进行实验性胃肠外给饲营养研究是很有价值的,特别引起我们兴趣的是使用不同营养方式来研究肿瘤生长。这种或那种方法的缺点是技术设计需很多加工工作,例如:支持导管的不锈钢支架和复杂的帆布工具。另一问题是必须使用特别适合鼠的营养溶液。因此我们设计了一种模型,它可以进行胃肠外给饲,维持时间可达数周以上。价格便宜,技术简单,每个医院都有能力进行。动物:试验证明胃肠外给杂交的Sprague-Dawley鼠投饲是有效的,这种鼠容易繁殖,在三月龄开始实验时体重可达400—500克。
It is valuable to conduct experimental studies of parenteral feeding with the rat model described by stiger, and we are particularly interested in using different nutritional approaches to study tumor growth. The disadvantage of this or that approach is that the technical design requires a lot of processing work, such as stainless steel stents for catheter support and complex canvas tools. Another problem is the need to use nutrient solutions that are particularly suitable for rats. So we designed a model that could be administered parenterally for up to several weeks. Cheap, simple technology, each hospital has the ability to carry out. Animals: Experiments have shown that feeding parenteral Sprague-Dawley hybrids is effective for mice that are easy to breed and can weigh up to 400-500 grams at the age of three months.
