1. Cyanide inhibited the uptake of vitamin C by human polymorphonuclear leukocytes (PMNs). 2. Preincubation of PMNs with cyanide had no effect on cytochalasin B-inhibitable uptake of dehydroascorbic acid (DHA) (the reversibly oxidized and transportable form of vitamin C). 3. Preincubation of DHA...
Algal bioassays were performed to investigate the toxic effect of cyanide on selected algal and cyanobacterial species. The results showed that Scenedesmus growth rate decresed as cyanide concentration increased. In contrast, cyanide did not affect the growth of Anabaena. Clear changes in dominancy and...
1The effects of intracarotid (i.a.) injections of acetylcholine (ACh) and sodium cyanide (NaCN) on baroreceptor activity recorded from the sinus nerve have been investigated in cats anaesthetized with pentobarbitone.2Two types of barorec... DS Mcqueen - 《British Journal of Pharmacology》 被引...
Cyanide, an inhibitor of many hemoproteins, was shown to affect a number of microsomal drug-metabolizing activities catalyzed by cytochrome P-450. The N-demethylation reaction of aminopyrine was inhibited noncompetitively by this inhibitor in microsomal preparations from rats. The binding reaction of...
An introduction to the existing methods for the analysis of cyanide is given and some of the limitations to the methods are pointed out.A modification of t... S Baar - 《Analyst》 被引量: 59发表: 1966年 Effects of amyl nitrite on circulation, respiration and blood homoeostasis in cyanide...
aIn contrast, the addition of potassium cyanide, 1 mM final concentration, had no effect on the appearance, transepithelial potential, or resistance after 2 hour of exposure 相反,氰化钾的加法, 1毫米最后的集中,没有作用在出现、transepithelial潜力或者抵抗在2个小时曝光以后[translate]...
Previous reports from our laboratory indicated that prophylactic protection against cyanide intoxication in mice can be enhanced by administration of chlorpromazine when it is given with sodium thiosulfate. The mechanism of potentiation of sodium thiosulfate by chlorpromazine was studied alone and in combinat...
Toxicity of cyanide is related to its inhibitory action on cytochrome c oxidase (COx). The α-keto acids pyruvate and α-ketoglutarate are known to exert in vivo certain protective effect against CN− toxicity if present when the poison is administered. We characterized in vitro their protection...
