vasoconstriction 中文意思是什麼

vasoconstriction 解釋
血管收縮
  1. The addition of epinephrine to local anesthetic solutions produces vasoconstriction.

    局麻藥溶液中加入腎上腺素，使血管收縮。
  2. Histamine causes vasoconstriction and increased permeability of small venules.

    組織胺能引起血管收縮，並增強小靜脈的透性。
  3. Although regional anesthesia, especially central conduction blockade, produces a favorable sympathectomy and increased limb blood flow, compensatory vasoconstriction in non - anesthetized areas may actually produce vaso - occlusive crises in these areas ( 5 )

    雖然區域麻醉，特別是中樞傳導阻滯可產生有效的交感神經阻滯並增加肢體血流，但是非麻醉部位發生代償性血管收縮，可能使這些部位發生血管阻塞性危象[ 5 ] 。
  4. Bernmof jl. one ? lung ventilation and hypoxic pulmonary vasoconstriction ： implication for anesthetic management. anesth analg 1985, 64 ： 821 33

    陶明哲.缺氧性肺血管收縮體液機制的研究進展.國外醫學麻醉學與復甦分冊1993 ， 14 ： 196 198
  5. Vasoconstriction and vasodilatation are separate mechanisms.

    血管的收縮和擴張分別具有不同的機理。
  6. 2. ne - evoked contraction was not significantly changed after the extracellular na + was replaced by choline and c4h12n +, but was relaxed when the extracellular cl - was replaced by glutamate and gluconate. moreover, the vasoconstriction induced by ne was further enhanced with the replacement of the extracellular cl " by br " and scn ", which was still sensitive to either nfa or nppb

    用氯化膽堿和四甲基氯化按分別替代灌流液中的氯化鈉后血管張力無明顯變化，在此基礎上nfa 、 nppb仍能抑制血管收縮，引起血管完全舒張；用通透性低的陰離子谷氨酸根和葡萄糖酸根分別替代灌流液中的q后血管發生舒張；用通透性高的陰離子br和scn分別替代灌流液中的ci后血管張力增加，並能被nfa 、 nppb所抑制。
  7. Wt5hzresults lnmma injection alone can inhibit the na induced vasomotion in vasoconstriction state, while si injection alone can inhibit it in vasodilation state

    結果單獨靜脈注射lnmma可使被誘導出的血管運動抑制于收縮狀態，單獨靜脈注射si可使血管運動抑制于舒張狀態。
  8. Both acute or chronic hypoxia can cause vasoconstriction and vasoconstriction increase

    急性或慢性的低氧都能使肺血管收縮，血流阻力增大。
  9. Wt5hzresults lnmma injection alone can inhibit the na induced vasomotion in vasoconstriction state, while si injection alone can inhibit it in vasodilation state. si could abolish the effect of lnmma on vasomotion but lnmma did not influence the effect of si on vasomotion

    在lnmma的有效作用時間內應用si可使被抑制于收縮狀態的血管重新擴張，血管運動得以恢復在si的有效作用時間內應用lnmma則不能使處于舒張狀態的血管收縮。
  10. Within six hours after an infant is placed in a high - oxygen atmosphere, vasoconstriction of the immature vessels of the retina occurs, which is reversible if the child is immediately returned to air, but irreversible if oxygen - rich therapy is continued

    嬰兒置於含氧濃度高的空氣中6個小時以內，未發育成熟的視網膜血管會發生血管收縮，如果立刻把孩子轉移到空氣中，這是可逆的，如果富氧治療繼續的話，會變成不可逆的。
  11. Sympathomimetics can elevate the body temperature by two mechanisms. firstly, vasoconstriction decreases skin blood flow and hence heat loss. secondly, metabolic heat production is increased

    擬交感神經作用藥物會令血管收縮，減少皮膚血液流量以致散熱減低，同時會增加代謝性熱能的產生，令體溫升高。
  12. This effect has been hypothesized to occur through an initial reduction in sympathetic outflow from the central nervous system with its associated decrease in vascular resistance, followed by a peripheral vascular receptor mediated increase in vasoconstriction ( 1, 4 )

    該作用被假設發生，通過對來自於中樞神經系統的交感系統的最初抑制，伴有相關的血管阻力的降低，並伴隨著外周血管受體介導的血管收縮的增加[ 1 ， 4 ] 。
  13. Ephedrine and phenylephrine can treat the hypotension, however an amplified vasoconstrictive response may be observed due to an alpha 2 agonist induced enhancement of baroreceptor reflexes ( 7 ) and potentiation of alpha 1 - adrenoceptor - mediated vasoconstriction

    麻黃素和苯腎上腺素可治療低血壓，然而可以觀察到存在過度縮血管反應，因為- 2受體激動劑導致壓力感受器反射[ 7 ]和- 1腎上腺素受體介導的血管收縮作用增強[ 8 ] 。
