血压

2 Hyperventilation produces small decreases in blood pressure in nor mal subjects and large decreases in patients with automatic failure.

过度换气会使正常受试者的血压轻微下降，而患有自律衰竭患者的血压下降幅度则较小。

Objective:To study the relationship between chronic hypotension and several plasma cytokines participating the regulation of blood pressure.

目的：研究人体血浆中可能参与血压调节的多种因子水平的改变与慢性低血压的关系。

Objective:To investigate the incidence of hypotension incidence which occurred differennt age of people.

目的：了解血液透析患者低血压发生与年龄，透析龄的关系，为低血压的防治提供依据。

Objective To observe the incidence of hypotension and hypertension during hemodialysis in different-age patients.

目的 观察不同年龄组血液透析中高血压及低血压的发生率。

In particular, some chronically ill patients with high blood pressure, high blood pressure because of the state has been compared to adapt, even if the blood pressure increased significantly, there is no clear feeling, which they think that their blood pressure is not high, so they delay treatment of hypertension.

特别是一些长期患病的高血压患者，由于对高血压的状态已经比较适应，即使血压明显升高，仍无明显的感觉，由此便认为自己的血压不高，于是便延误了对高血压的治疗。

Interestedly, the BP in Zn DPBG and L-arginine (L-Arg, NOS substrate)-treated group was significantly de creased compared with that in ZnDPBG-treated group solely, although it was sti l l higher than that of control group.

同时加入ZnDPBG和NOS底物左旋精氨酸(L-arginine， L-Arg)，血压虽然仍高于正常，但比单纯ZnDPBG处理的大鼠血压要明显降低，此时iNOS活性和［NO2-］产生的增加更明显。

Methods: Separate and abstract the effective components of Huangqi (Omni-Saponin、total-flavone) and Danshen (Danshen-ketone、 Danshen-Quinone). Applying L-Arginine methyl ester to pregnant rats by I. P to make Nitrogen Oxide Synthesis blocking models (uterus-placenta-fetus lacking blood and oxygen model or pregnant hypertension syndrome model). On day 12, 18 of pregnancy paunched the rats and took out the fetus and placenta/uterus. Measured the basal BP during pregnant period and BP、protein、basal activity each day. Observed placenta/deciduas ultramicroscopic structure by electron microscope and took count of languishment cells. Measured the expressive intensity of bcl-2、Bax of placental nutrient cells by SABC method.

一氧化氮合成酶阻滞剂L-精氨酸甲酯妊娠大鼠腹腔给药，制作一氧化氮合成阻滞模型（子宫-胎盘-胎儿缺血缺氧或妊娠高血压模型），妊娠第12、18天剖腹取胎、胎盘／子宫，妊娠期测基础血压，每日测血压、蛋白质量、基本生理活动；电镜观察胎盘／蜕膜超微形态结构，并进行细胞凋亡计数；免疫组化检测胎盘滋养细胞bcl-2、Bax表达强度；原位杂交法检测胎盘滋养细胞、血管内皮细胞VEGF、eNOS、iNOS、MCP-1、MMP9（基质金属蛋白酶9）mRNA表达。

The length of combination of strengths: normal blood pressure within 24 hours of "a valley of two peaks," the changes of blood pressure in diabetic patients with high blood pressure fluctuations is even more apparent.

长短结合，优势互补：正常血压24小时内有"两峰一谷"的变化规律，糖尿病高血压患者的血压波动就更明显了。

A common type of hypotension is postural hypotension, in which suddenly standing leads to light-headedness and fainting.

一种常见的是姿势性低血压低血压，在突然站立导致轻的头脑和昏厥。

Objective To study the prevalence and relevant risk factors of low blood pressure and its influence on cardiovascular diseases in China.

目的 了解我国人群低血压的患病率、危险因素以及低血压对心血管病的影响。

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。
