Perfluorochemicals are compounds in which all the hydrogen atoms have been replaced by fluorine atoms. Because of their high capacity to dissolve oxygen, perfluorochemicals have been used as artificial oxygen carriers in organ perfusions. Previous experiments suggested that perfluorochemicals failed to support testosterone secretion by rat testes. We hypothesized that fluoride ions in the perfusion medium may have been the toxic factor. We tested this hypothesis by adding sodium fluoride to perf
In our work we have often dealt with patients who were diagnosed with “rheumatic or rheumatoid arthritis” in rural basic medical units or certain hospitals. A minority of those patients did have rheumatoid arthritis, but most of them did not improve with anti-rheumatic pharmacotherapy for multiple years; instead, their conditions worsened increasingly. Some of them had a bent waist and hunched back such that they could not manage their own life, and some patients had even progressed to paral
