Both adult and larval, contain toxins of great virulence, though in.
Amongst these may be mentioned the neutralizing of the toxins in cases of diphtheria, tetanus and poisonous snake-bite; " serum therapeutics "; and treatment by " vaccines."
It has been proved that the pyo-genic bacterial toxins, if not too concentrated, will attract the polymorpho-nuclear leucocytes, but if concentrated, may have a repelling influence.
This splitting up of the fats previously combined with albumin in the cell by the action of natural ferments - lipases - and the setting free of the fats under the influence of toxins represent the normal and the pathological process in the production of so-called fatty degeneration.
Hyaline degeneration is found in certain acute infective conditions; the toxins specially act on these connective-tissue cell elements.
