After the updates of the new page: The Etiology of Schizophrenia – CS2. The work now continues by following the metabolism from CS2 to H2S in what could be and the reactive core in the etiology of Schizophrenia. Up next are the effects of H2S.

But first of all let us see that the CAC-hålet theory shows that the reactive substance CS2 which in itself can cause some of the symptoms in Schizophrenia and is metabolized to Hydrogen Sulfide – H2S in the body, by a new route.  CS2 is also detected in the exhaled air from persons with Schizophrenia.

Aspiration and Respiration

The core function in aspiration is gas exchange with the biosphere and to regulate the breathing to the needs of the cellular respiration. In schizophrenia the Carbonic Anhydrase Catalysis – CAC is slower than normally resulting in a prolonged hypoxia in the mitochondria after increases in the O2 consumption, part of these fundamentals are later shown in the BOLD fMRI where the blood oxygenation levels curve are steeper in persons with schizophrenia.

CS2 and the metabolites dithiocarbamates and H2S are potent inhibitors of CAC, this will result in a further decrease in the function of Carbonic Anhydrase and the CO2 reactivity will get even slower. Or the other way around, H2S is the mother-substance to the reaction.
