Homogeneous staining was detected in small neurons (thick arrow) as well as intracytoplasmatic granular staining (arrow head). c. A similar immunoreactivity as for fresh animals was detected in the vehicle group, with thin fibre (thin arrow), small neurons (thick arrow) and granular cytoplasmatic (arrow head) staining. d-i. A pearl like staining was observed in thin fibres (thin arrow), homogeneous staining was detected in the small neurons (thick arrow) as well as intracytoplasmatic granular staining (arrow head).
