1 INTRODUCTION The breeding of Standardbred horses for harness racing is a significant activity in many countries. However, despite the existence of a large commercial industry, there is little published literature on the reproductive efficiency of Standardbred horses in any of the harness racing countries.

Neuroinflammation Glial cell activation was assessed over disease progression by immunohistochemistry, using GFAP as an astrocytic marker and GSB4 lectin histochemistry to detect microglia. Low-level GFAP reactivity was limited to quiescent protoplasmic astrocytes in lamina 1, adjacent to the pial surface, or distributed evenly within the gray matter laminae and white matter tracts in control brains at all ages (Figure 6a).

Although C-type natriuretic peptide (CNP) has high abundance in brain tissues and cerebrospinal fluid (CSF), the source and possible factors regulating its secretion within the central nervous system (CNS) are unknown. Here we report the dynamic effects of a single IV bolus of dexamethasone or saline solution on plasma, CSF, CNS and pituitary tissue content of CNP products in adult sheep, along with changes in CNP gene expression in selected tissues.
