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
1967 research showed microwave radiation could affect immune system mast cells in rats, providing early evidence of biological responses.
Plain English Summary
This 1967 study examined how microwave radiation affects mast cells in the mesentery (abdominal membrane) of laboratory rats. Mast cells are immune system components that release histamine and other inflammatory substances when activated. The research found measurable effects on these cells, contributing early evidence of biological responses to microwave exposure.
Why This Matters
This research represents some of the earliest documented evidence that microwave radiation can trigger biological responses in living tissue. What makes this study particularly significant is its focus on mast cells, which serve as the body's first responders to potential threats and play crucial roles in allergic reactions and inflammation. When mast cells are activated inappropriately, they can contribute to chronic inflammation and various health problems.
The fact that researchers in 1967 were already documenting cellular-level effects from microwave exposure should give us pause about today's ubiquitous wireless environment. Modern microwave ovens, WiFi routers, and cell phones all operate in similar frequency ranges to what was studied here. While we can't know the specific power levels or exposure duration from this early technical report, the demonstration of biological effects at the cellular level suggests our immune system's surveillance cells have been responding to artificial microwave radiation for decades.
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
