Methods Wistar rats were divided into four groups:normal group(n=8),model group with cirrhosis and portal hypertensive gastropathy(n=12),disconnective group(n=12)and post-disconnection plus CGRP group (n=12).Gastric mucosal cellular proliferative parameters from the above groups were measured by the radioscintigraphy.

Wistar大鼠分正常对照组8只，肝硬变合并门静脉高压性胃病(portal hypertensive gastropathy，PHG)模型对照组12只，断流手术组12只，断流术加CGRP保护组12只，用放射自显影技术测定各组胃粘膜细胞增殖参数。

Methods Neonate rats were irradiated with a single injection of 2 μl enriched*" 235 uranium( 235 U)into the lateral ventricle of the rat brain on the first day of life(less than 24 hours after birth)at doses of 0,1,5 and 10 μg of*" 235 U,respectively.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
