Summary
We have already discussed the view of Kuhne in 1864 that death rigor had three causes, all contributing to precipitation and coagulation of the muscle proteins – the precipitation of the globulin (myosin) fraction in a manner resembling its precipitation on dilution; the precipitation of the albumin fraction under the influence of lactic acid; and the operation of a clotting activator.
We come now to the experiments of Claude Bernard, already briefly mentioned in chapter 5. Part of the very clear description in his book (2) of 1877 may be quoted here:
It has even been thought possible to lay down a general rule that muscular rigidity and acid reaction were two phenomena essentially bound the one to the other. This is not so; the two phenomena are not bound the one to the other; it is the presence of the glycogenic substance which is the necessary forerunner of the acid reaction of the muscle, this reaction arising essentially from the lactic fermentation of the glycogenic matter. If in fact one kills an animal after having made its muscle glycogen disappear, the rigidity of the corpse comes on although the muscle conserves its alkaline reaction. For this effect, it is enough to kill the animal by starvation, which has the result of completely depriving the muscle tissue of glycogenic matter; on this account the rigid muscles are not acid: thus no glycogen in the muscle, no lactic acid in its tissue.
