To verify availability of skin conductance (SC) as an indicator for the sympathetic nervous system (SNS) activity in dogs, the changes in SC and blood levels of stress-related hormones induced by drugs were compared. SC and cortisol, adrenaline and noradrenaline levels were measured in 5 dogs on 4 occasions with or without drug-induced sedation at 7-day intervals (no treatment, intramuscular medetomidine 0.01 mg/kg, intramuscular acepromazine 0.1 mg/kg and intravenous fentanyl 0.02 mg/kg). The fentanyl treatment produced significantly higher levels of SC and plasma cortisol and adrenaline compared with the other 3 treatments. The plasma noradrenaline level also tended to be higher following the fentanyl treatment. These results indicate that SC may reflect changes in the SNS activities in dogs.

Recently, hyperbaric oxygen therapy with a lower pressure and oxygen concentration (L-HBOT) than previous methods has been used for dogs in Japan; however, the influences of L-HBOT on dogs have not been clarified. To verify the influences of L-HBOT on physiological mechanism in dogs, we investigated blood gas parameters, glutathione peroxidase (GPx) activity, heart rate variability, stress-related hormones and skin conductance (SC) in 4 clinically normal beagle dogs with catheters in their carotid arteries and jugular veins when they were quiet, after running, after receiving L-HBOT (30% oxygen concentration, 1.3 atmospheres absolute, 30 min) or after not receiving L-HBOT. The results showed there were no changes in blood gas parameters, heart rate variability and catecholamine levels after L-HBOT. GPx activity was significantly higher, and the SC and cortisol level were lower in dogs that received L-HBOT than those when they were quiet. These results suggested that L-HBOT may have a small influence on oxygenation dynamics, activate antioxidant enzymes such as GPx, restrain autonomic nervous activity and control the balance between oxidation and antioxidation inside the body.
