An inorganic pyrophosphatase has been purified to apparent homogeniety from Indian cobra(Naja naja) venom, with a ten-fold increase in specific activity. The enzyme activity is intrinsic to a protein fraction in the venom which is normally termed cardiotoxin, cobramine, cytotoxin and so on. The enzyme shows a lowKm (70 μI) and high heat stability. The enzyme was active against sodium pyrophosphate; it also hydrolyses a few mononucletides and sugar phosphates at much lower rates. The… Expand

Outcomes of Snakebite Envenomation in Children
TLDR
Compared with adults, children with snake envenomation have higher morbidity and mortality, which can be minimized by early diagnosis, appropriate treatment and close monitoring of children on ventilation for the timely management of complications. Expand

TLDR
Dried cobra venom has beeb dialysed under various conditions and the venom hydrolyses inosine triphosphate and coenzyme A in a manner analogous to the breakdown of ATP and DPN respectively. Expand
The toxic proteins of cobra venom.
TLDR
Carboxymethyl cellulose chromatography permits separation of five distinct toxic proteins from the venom of the Indian cobra, including cobramines A and B, which are less toxic than the crude venom and account for its cardiotoxic activity. Expand
