呼吸中枢

The main pathway is acting directly on peripheral chemoreceptor and inputting impulse.respiration center is excited.

主要是直接作用于外周化学感受器，传入冲动。呼吸中枢呈兴奋作用。

In section of control of ventilation, students will learn respiration centers (medullary center, apneustic center, pneumotaxic center), and are required to master pulmonary stretch reflex (Hering-Breuer reflex), to understand other respiratory reflexes, to master the site and features of central chemoreceptor

了解节律性呼吸运动的起源。掌握肺牵张反射，了解其他呼吸反射。化学因素对呼吸活动的调节，掌握外周化学感受器与中枢化学敏感区的定位和功能特点，血液CO2、H+、O2浓度的变化对呼吸活动的影响及其作用机制。

TMP has protective effect on the respiratory inhibition induced by hypoxia and FOS may be involved in the protection.

TMP对呼吸中枢的缺氧性损害具有保护作用，脑干内FOS蛋白可能参与了这一过程。

AIM: To observe the effect of pentoxifyllinel on inhibition of respiration induced by acute poisoning with pentobarbital sodium , and to study the mechanisms for action of pentoxifyllinel on antagonizing the central inhibition of respiration resulted from the barbitalism.

目的： 观察己酮可可碱对急性戊巴比妥钠药物中毒所致呼吸抑制的影响，探讨其在解救巴比妥类药物中毒所致中枢性呼吸抑制中的作用及机制。

The results indicate that in vitro brainstem-spinal cord preparation has powerful advantages in studies of respiratory center.

结果提示新生大鼠离体脑干－脊髓制备用于哺乳类呼吸中枢的研究具有独特的优点

The influences from respiratory center and feedback from pulmonary stretch receptors were simulated.

并加入了呼吸中枢以及来自肺牵张受器的回馈模拟。

When the baby when a normal birth, the baby's head will be squeezed, the pressure of the baby's birth canal is a good stimulation of the sensory organs, which stimulate the conduction brain, right brain circulation of blood to enhance stimulation of the brain's respiratory center to provide more material basis of the baby's hearing and so on is a very good training, while caesarean section babies have lost the opportunity to exercise.

当宝宝正常分娩的时候，宝宝的头部会受到挤压，产道的压迫对宝宝的感觉器官是一种良性刺激，这种刺激传导大脑，对脑部血管循环加强刺激，为脑部的呼吸中枢提供更多的物质基础，对宝宝的听觉等是一次非常好的训练，而剖腹产的宝宝则失去了这一锻炼机会。

Therefore, we focus on the expression of TASK-1 mRNA in the brainstem respiratory-related neurons and the possible regulatory mechanisms of TASK-1 to the central chemorespiration, It can definitely help us better understand the possible function of TASK-1 channel in the respiratory center.

本实验旨在观察TASK-1在大鼠低位脑干的表达及其对中枢化学性呼吸的调节，探讨TASK-1对中枢性呼吸的调控作用。

When microinjection of medicine into VLNTS induced the changes o f activity of respiratory center, the effects of laser irradiation of "chest and lung area" on these changes were observed.

记录膈神经放电，于延髓孤束核腹外侧区微量注射药物，改变呼吸中枢的活动，观察激光照射耳廓&胸肺区&对这些活动改变的影响。

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。
