Fig. 12-1. Contractile response of the cranial branch of the bovine lateral saphenous vein in vitro to various alkaloid treatments. Data were compiled from several published (Klotz et al. 2006, 2007) and unpublished research trials (unpublished data, J.R. Strickland lab, 2007). (A) Contractile response of ergovaline in vessels collected from abattoir animals (Klotz et al., 2007) and surgical biopsy of naïve animals (Klotz et al., 2008). (B) Contractile response of ergocryptine in vessels from biopsy of naïve animals (Klotz et al., 2008) and ergotamine response in vessels collected from abattoir animals (Klotz et al., 2007). (C) Contractile response of lysergic acid, ergonovine, and ergocryptine in vessels biopsy of naïve animals (Klotz et al., 2008) and lysergic acid in vessels collected from abattoir animals (Klotz et al., 2007). (D) Contractile response of N-acetylloline in vessels collected from abattoir animals (Klotz et al., 2008).
