The Basic Proteins of Cobra Venom
Cobra venoms contain heat stable, basic, proteins that inhibit iodide accumulation by thyroid slices. Activity is not related to the content of phospholipase A or various other enzymatic activities. These proteins are present only in Elapid venoms and not in snakes of the Crotalidae or Viperidae families. Two such basic proteins, named cobramines A and B, have been purified from the crude venom...
متن کاملCobra Venom Factor and Ketoprofen Abolish the Antitumor Effect of Nerve Growth Factor from Cobra Venom
We showed recently that nerve growth factor (NGF) from cobra venom inhibited the growth of Ehrlich ascites carcinoma (EAC) inoculated subcutaneously in mice. Here, we studied the influence of anti-complementary cobra venom factor (CVF) and the non-steroidal anti-inflammatory drug ketoprofen on the antitumor NGF effect, as well as on NGF-induced changes in EAC histological patterns, the activity...
متن کاملNerve growth factor from cobra venom.
The chemical and biological properties of the nerve growth factor isolated from Naja naja venom are described. The nerve growth promoting activity appears to be distinct from the most commonly known enzymes and toxins present in the venom. The purified nerve growth factor from cobra venom has properties remarkably similar to those of the nerve growth factor isolated from mouse submaxillary glan...
متن کاملCobra Venom-induced Hemolysis
Interest in the alternate or C3 shunt complement pathway has recently been generated by a number of reports (1-5). Its presence in invertebrates points to a primitive phylogenetic appearance (6). The C3 shunt can be triggered by high molecular weight polysaccharides in a manner reminiscent of the properdin system (7). Once activated by cobra venom, erythrocytes and other cells can be lysed in t...
متن کاملA Neurotoxin, Toxin a, from Egyptian Cobra (hjcz haje haje) Venom
A neurotoxin, designated toxin LY, has been isolated from the venom of the Egyptian cobra (Naja haje haje) by gradient chromatography on Amberlite CG-50, and has been further purified by gel filtration on Sephadex G-50. Homogeneity was verified by free boundary electrophoresis, acrylamide gel electrophoresis, sedimentation velocity, amino acid analysis, and end group analysis. Toxin LY has a se...
