Snake Venoms Containing NGF
Oftentimes, this nerve growth factor occurs in the cobra family. Cobra
venom seems to contain the highest amount of NGF of all the snake
venoms.
Viperidae Bothrops jararaca
Bitis gabonica Crotalus adamanteus
Echis carinatus Crotalus atrox
Echis coloatus Crotalus horridus
Vipera ammodytes Crotalus terrificus
Vipera aspis Elapidae
Vipera russellii Dendroaspis viridis
Crotalidae Naja melanoleuca
Agkistrodon piscivorus Naja naja
Ancistrodon contortrix
lactocinctus
Naja nigrocollis
Ancistrodon rhodostoma Sepedon haemachatus
The venom of the Black Mamba, Dendroaspiaspsis jamesoni, causes
marked depolarization of membranes and inhibits the excitability of
skeletal muscles. This can effect cardiac and respiratory function;
whereas, the cobra venom is primarily neuro-toxic and causes
degenerative tissue to form. The venom of the families of the viper and
rattlesnake are primarily related to hemorrhages and coagulation
disturbances. The enzyme effect of these different venoms can start lysis
in red cells as well as other cells of the body. This is to prepare the
intended victim for digestion. Cobra venom lowers the red blood cell
count in victims, but this alone does not seem to produce lethal effects.
The most powerful hemolytic snake is the Pseudechis papuans, also
known as the Papuan black snake. People bitten by this snake often
produce red or black urine which results from the breakup of red blood
cells. The hemolysis effects are profoundly proteolytic, and this venom
offers homeopathy some interesting challenges.
