我们将昆明种雌性小白鼠８１只，分为四个组，各组均喂统一饲料。第一组１６只，每日施以两小时噪声；第二组也是１６只加喂中药补阳还五汤精膏；第三组１６只加喂维生素Ｅ（９０ｍｇ／ｄ．ｋｇ）；第四组３３只作为对照组。用体视学方法测出各组小鼠大脑额叶神经元的细胞核体密度和胞体细胞质体密度。利用线性回归法对各组进行分析，发现噪声影响了小鼠额叶神经元的核质比。本文简要地讨论了它们的意义。 We will Kunming female mice 81, divided into four groups, each group were fed a unified feed. The first group of 16, two hours a day to impose noise; the second group is also fed 16 Chinese medicine Buyang Huanwu Tang cream; the third group of 16 fed with vitamin E (90mg / d.kg); the fourth Group 33 only as a control group. The body nucleus density and cytoplasmic cytoplasm density of the frontal lobe neurons in each group were measured by stereological methods. Using linear regression analysis of each group, it was found that noise affected the ratio of nucleoli to the frontal lobe of mice. This article briefly discusses their meaning.
