Figure 3From: Inhibitors of endopeptidase and angiotensin-converting enzyme lead to an amplification of the morphological changes and an upregulation of the substance P system in a muscle overuse model A series of sections of a soleus muscle specimen of an animal subjected to muscle overuse and injections with C + Th. The sections were stained with H&E (A), and processed for SP (antibody sc-14104) (B) and NK-1R (C). There are numerous white blood cells in a connective tissue area located in-between muscle fibers. There is presence of SP-like and NK-1R immunoreactions in these cells. A large number of the cells in this area are eosinophils. Bars = 25 μm.Back to article page
