In situ hybridization detection of tachykinin mRNA in cells of inflammatory infiltrate. Sections of a gastrocnemius muscle specimen of the 1w group, exercised side. In situ hybridization (A: antisense staining, B: sense staining). (A) and (B) are from the same region of the specimen. There is a presence of tachykinin mRNA reactions in the form of black granular reactions in scattered cells of an inflammatory infiltrate of a focal myositis area (arrows). There are no reactions in the sense control. Arrows point at white blood cells. Magnification x315.
