Although sodium nitroprusside (SNP) is often used in pediatric intensive care units, cyanide toxicity can occur after SNP treatment. To treat SNP-induced cyanide poisoning, antidotes such as amyl nitrite, sodium nitrite, sodium thiosulfate, and hydroxycobalamin should be administered immediately after diagnosis. Here, we report the first case of a very young infant whose SNP-induced cyanide poi...

Sodium nitroprusside (SNP) is an anti-hypertensive drug, commonly used to decrease the systemic vascular resistance and lower the blood pressure. When the amount of cyanide generated by the SNP exceeds the metabolic capacity for detoxification, cyanide toxicity occurs. Under general anesthesia and cardiopulmonary bypass (CPB), it may be difficult to detect the development of cyanide toxicity. I...

Three patients presented with painless bilateral visual failure due to tobacco amblyopia. The whole blood cyanide levels were raised above those predicted from their high tobacco consumption, approaching lethal levels reported from acute inhalation of cyanide. Each patient had an excessive alcohol intake with biochemical evidence of hepatic dysfunction, the elevated whole blood cyanide levels b...

Cassava leaves, which usually contain large quantities of cyanogenic glycosides, were processed into a Zairian traditional vegetable sauce "Mpondu" by simple methods which included blanching (10 min), mashing and then boiling for 20-80 min. These methods enhanced the detoxification of the leaves, with blanching alone resulting in the loss of 57% of the free (non-glycosidic) cyanide content and ...

Sodium nitroprusside is an excellent agent for lowering blood pressure in hypertensive emergencies, for producing controlled hypotension during anesthesia, and for treating acute myocardial infarction and chronic heart failure. Toxic effects of this drug have been reported and above-normal cyanide and thiocyanate concentrations have been observed in the blood of a small proportion of subjects r...

Cisplatin holds an illustrious position in the history of chemistry most notably for its role in the virtual cure of testicular cancer. Here we describe a role for this small molecule in cyanide detoxification in vivo. Cyanide kills organisms as diverse as insects, fish, and humans within seconds to hours. Current antidotes exhibit limited efficacy and are not amenable to mass distribution requ...

Detoxification of Semen Armeniacae Amarum requires large amounts water, and the detoxifying wastewater contains highly toxic hydrocyanic acid. This paper aims to explore recovery water after removal cyanide from it by chemical precipitation. The results show that when dosage ferrous sulfate is 1.76 times theoretical value, in can be reduced about 2.70×105mol/L, acid entirely removed treated rec...

Concern over poisoning as a result of eating cassava roots or shoots has led to these studies to determine factors which lead to high cyanide content in these tissues and how detoxification can be carried out. Plant age or stage of development does not seem to have a clear influence on root or shoot cyanide content. Genetic control on cyanide content seems significant as varieties may be identi...

this study was undertaken to estimate specific activities of rhodanese and 3-mercaptopyruvate sulfurtransferase (mst) in different tissues of turkey. enzyme activities were determined in tissue samples from freshly killed adult male turkeys by measurement of thiocyanate amounts produced by the action of enzymes on suitable substrates. activities of rhodanese and mst in examined tissues of turke...

A Rhodococcus sp. UKMP-5M isolate was shown to detoxify cyanide successfully, suggesting the presence of an intrinsic property in the bacterium which required no prior cyanide exposure for induction of this property. However, in order to promote growth, Rhodococcus sp. UKMP-5M was fully acclimatized to cyanide after 7 successive subcultures in 0.1 mM KCN for 30 days. To further shorten the lag ...
