The removal activity deactivated at a higher temperature remained after the addition of sodium azide, and the 50% inactivation was observed at 63.5 +/- 1.4 degrees C.

High concentrations of equilin or estrone also attenuated the submaximal neuronal injury induced by 3.5-4.5 h exposure to the cytochrome oxidase inhibitor sodium azide, with near complete protection at 30 microM.

Virus (R17 bacteriophage) photoinactivation by either activated monomer or dimer DMMB was suppressed by sodium azide (singlet oxygen quencher) and promoted by the substitution of H2O for deuterium oxide (D2O), which is known to prolong the lifespan of singlet oxygen.

Washed red blood cells (RBCs), supplemented or non-supplemented with sodium azide (to inhibit catalase activity), were exposed to different concentrations of hydrogen peroxide as well as ascorbic acid.
Oxyhemoglobin, with an excess of hydrogen peroxide, formed oxidized hemoglobin species and caused protein denaturation as well as the rise of heme degradation products which was suspected to falsify zinc protoporphyrin/heme (ZPP/heme) ratio as assessed by hematofluorometry.

The tetracycline photoeffects on hemoglobin, catalase and possibly other heme-containing proteins were likely realized in the immediate closeness of their hemes.
When tetracycline and chlortetracycline were incubated an a dark room in the presence of erythrocytes with erythrocytic catalase completely inactivated by sodium azide, the antibiotics induced methemoglobin formation in them.

Hemoglobin was found to enhance hemolysin secretion.
However, the addition of sodium azide, an energy metabolic inhibitor, significantly reduced the hemolytic activity.
