exogenous toxin 中文意思是什麼
-
In this experiment, seedlings of arabidopsis thaliana ( col ) were observed after being treated by verlicillium dahliae ( vd - toxin ), exogenous salicylic acid ( sa ), nitric oxide donor ( snp ) and nitric oxide synthase inhibitor ( nna ), then we investigated the changes of endogenous h2o2 content, the activity of the antioxidant enzymes catalase ( cat, ec : 1. 11. 1. 6 ) and ascorbate peroxidase ( apx, ec : 1. 11. 1. 11 ) and mrna levels of cat3 in different stress conditions, we also identified the localizations of h2o2 and no accumulated in the leaves of arabidopsis
本實驗研究了棉花黃萎病菌?大麗輪枝菌毒素（ vd - toxin ）與擬南芥幼苗互作反應中外源sa 、 no供體snp 、 no合酶抑制劑nna等不同處理對擬南芥幼苗h _ 2o _ 2含量、 cat和apx活性及cat基因mrna表達量的影響，並對no 、 h _ 2o _ 2的積累部位進行染色檢測。 -
It was found that plc activity was stimulated by both exogenous purified calmodulin and heterotrimeric g protein agonist cholera toxin. while, the stimulated effect on plc activity caused by exogenous calmodulin was inhibited by heterotrimeric g protein antagonist pertussis toxin, and plc antagonist u - 73122 inhibited the effect caused by cholera toxin. we also measure the free ca ~ ( 2 + ) level in germinating pollen grains, and found that exogenous purified calmodulin was able to increase the free ca ~ ( 2 + ) level, and their effects on ca ~ ( 2 + ) level were inhibited by u - 73122
實驗中，利用[ ~ 3h ] pip _ 2和花粉原生質體共同孵育的體系，檢測出了百合花粉細胞具有依賴pip _ 2的plc活性；利用該體系還檢測出外源鈣調素可促進plc的活性，其中10 ~ （ - 9 ） m的鈣調素可使plc的活性提高三倍；異三聚體g蛋白的激活劑ctx可以激活plc的活性，而其抑制劑ptx可明顯抑制plc活性；外源鈣調素的這種作用可以被ptx抑制；而plc抑制劑u - 73122抑制ctx對plc的激活效應。 -
The liver is an important organ in the body where protein synthesis and metabolism of exogenous and endogenous substrates are performed. liver is very sensitive to exogenous toxin injure
很早就發現多種生物、理化因素引起肝臟損傷的同時，伴隨有新生細胞的產生、增殖和分化，以修復損傷並維持肝臟功能的正常發揮。
