Fig. 2From: Changes in energy metabolism, and levels of stress-related hormones and electrolytes in horses after intravenous administration of romifidine and the peripheral α-2 adrenoceptor antagonist vatinoxanMean serum FFA concentration of seven horses. The horses received romifidine (ROM, 80 μg/kg IV), ROM with vatinoxan (ROM + V, 80 μg/kg + 200 μg/kg IV) and vatinoxan (V, 200 μg/kg IV) at T0. Error bars indicate the standard deviation. Serum FFA concentrations were significantly different (P < 0.05) from baseline at T30 after ROM, at T15 and T30 after ROM + V and at T30 and T60 after V. Significant difference (P < 0.05) between †ROM + V and V and ‡ROM and VBack to article page
