Experimental Contribution to the Study of the Effects of Microwaves on the Mesenteric Mast Cells of the Albino Rat
Taccari, E., Crespi, M., Ddainotto, F. · 1967
Early research showed microwaves could affect immune system mast cells in rats, foreshadowing today's EMF health concerns.
Plain English Summary
This 1967 Italian research examined how microwave radiation affects mast cells in the mesenteric tissue of laboratory rats. Mast cells are immune system components that release histamine and other inflammatory substances when activated. The study represents early experimental work investigating whether microwave exposure could trigger immune system responses in living tissue.
Why This Matters
This research from 1967 represents pioneering work in understanding how microwave radiation interacts with our immune system at the cellular level. Mast cells are critical immune components that, when activated inappropriately, can trigger allergic reactions and chronic inflammation. The fact that researchers were investigating microwave effects on these cells over 50 years ago shows that concerns about EMF immune system impacts aren't new. What makes this particularly relevant today is that we're now surrounded by microwave-emitting devices at power levels and exposure durations that far exceed what people experienced in 1967. Your smartphone, WiFi router, and microwave oven all operate in similar frequency ranges to what this research examined, yet we carry these devices against our bodies for hours daily.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: 5 minutes
Study Details
To analyze the behavior of the mast cells of the mesentery of the rat following panirradiation with ultrashort waves, to show possible changes in the cells under examination, and to attempt in that way to interpret the reaction of the connective substratum to which they belong, under the stimulus of microwaves

Our observations have made it possible to show how panirradiation with microwaves can cause a change in the mast cell population in the mesentery of the rat, characterized by an increase in the average diameter and by the degranulation of those cells; it remains to be established whether that change is caused primarily by a direct action exerted by the microwaves on the mast cells and therefore representing an immediate response of those cells to the exogenous stimulus, or rather the expression of heightened mast cell activity associated with biochemical changes caused by the panirradiation in the mesenteric connective tissue. The experimental observations of mast cells subjected to stimuli capable of acting directly on them, as for example the intraperitoneal injection of compound 18/80 which is capable of causing their degranulation, actually through an enzymatic mechanism, demonstrate how those cells react to a similar type of stimulus with rapid, total degranulation. Therefore, it seems reasonable to consider that microwaves are able to cause a biochemical change in the mesentery, and that the morphological changes observed, in the mast cell population represent the expression of the activity of those cells heightened by the above-mentioned changes, thus constituting an initial stage in the more complex homeostatic mechanism for maintaining the integrity of the connective tissue and of its fundamental substances described by Riley
