Human alveolar macrophages spontaneous reduction of BSPT salt.

Alveolar macrophages of non smoking and smoking human adults reduce BSPT salt spontaneously. The staining obtained is located on three cell membrane systems: the endoplasmic reticulum, the Golgi apparatus and the nuclear envelope. Methylene blue MB inhibits BSPT reduction. The smokers alvelolar macrophages have less positivity than those of the non smokers. The endogenous cell substrate revealed in this work is the initial common pathway of two different oxidative chains bounded to the microsome. One acts with cytochrome P 450 for chemical detoxification by hydroxylation, the other one acts with cytochrome B5 for lipid oxidation or peroxidation and both may be connected with the cell bactericidal system.

The location of non-specific esterase in human lung macrophages. An ultrastructural study.

The non-specific carboxyl (serine) esterase of the human pulmonary alveolar macrophage was localized ultrastructurally using alpha-naphthyl acetate and hexazotized pararosanilin. The reaction product principally outlined the outer side of the plasma membrane. Consequently, this esterase is an ectoenzyme which may function as mediator of cell response to injurious agents from the outside.
