    We investigated the characteristics of arterial blood pressures and heart rate (HR) in bronchial-hypersensitive (BHS) and bronchial-hyposensitive (BHR) guinea pigs under conscious state. Arterial blood pressures (systolic blood pressure; SBP, mean blood pressure; MBP, diastolic blood pressure; DBP) were measured using a recently developed oscillometric device. The values of measurement parameters are as follows; BHS (HR: 253.5±5.1, SBP: 105.7±1.6, MBP: 75.1±1.9, DBP: 60.0±2.2) and BHR (HR: 253.7±4.2, SBP: 106.8±1.3, MBP: 72.7±1.6, DBP: 55.8±1.9). We could not observe any differences in arterial blood pressures and HR between these strains. These results suggest that airway hyperresponsiveness is not significantly affected on the cardiovascular functions under resting conditions.

    The azygos veins were anatomically investigated in 100 Japanese black and 50 Holstein cattle, and were divided into 4 types. The left azygos vein dominant type was observed in 71 Japanese black and 42 Holstein cattle. The left azygos vein draining into the anterior vena cava was observed in a Japanese black cattle. The left azygos vein receiving the left costocervical vein was observed in six Japanese black and three Holstein cattle. The anomalous posterior vena cava with azygos continuation was found in four Japanese black and a Holstein cattle.

    It is important to know the standard electrocardiographic values in each dog breed because of variety of body size and anatomical difference of the chest. Since Retrievers are originated from the hunting dog, their electrocardiogram (ECG) values might be different from standard normal range of the dogs. The purpose of this study is to determine the standard ECG of Golden Retrievers and Labrador Retrievers, and if their values of each ECG measurement are different from standard ECG values. Six-lead ECGs were taken from 57 Labrador Retrievers and 34 Golden Retrievers. Amplitude and duration of P wave and QRS complex, PR interval, QT interval and mean electrical axis were measured in each ECG strip. Labrador Retrievers showed deep Q waves in lead I, II and aVF. Golden Retrievers showed tall R waves in lead II and aVF. It was indicated that Retrievers had a specific shape of QRS complex. It is needed to notice the characteristics when diagnose ECG.

    Twenty dog lungs were examined. The right pulmonary artery runs across the ventral side of the right cranial lobe bronchiole, then across the dorsal side of the right middle lobe bronchiole. Thereafter, the right pulmonary artery runs along the dorso-lateral side of the right bronchus. During its course, the right pulmonary artery gives off arterial branches that run mainly along the dorsal or lateral side of each bronchiole. The left pulmonary artery runs across the dorsal side of the left middle lobe bronchiole, and thereafter has the same distribution as that in the right lung. The pulmonary vein runs mainly along the medial or ventral side of the bronchiole, and between the bronchioles. In the right lung, the right cranial and middle lobe veins form a short common trunk, when enter the left atrium. The right accessory lobe vein enters the right caudal lobe pulmonary venous trunk. The right caudal lobe pulmonary venous trunk enters the left atrium. In the left lung, the left middle lobe vein has two branches. Both enter the left atrium, forming a short common trunk. In addition to these veins, the left caudal lobe pulmonary venous trunk enters the left atrium.

    The right pulmonary artery runs obliquely across the ventral side of the tracheal bifurcation and across the ventral side of the right cranial lobe bronchiole, then runs across the dorsal side of the right middle lobe bronchiole. Thereafter, it runs between the dorsal and lateral bronchiole systems along the dorso-lateral side of the right bronchus and gradually comes to run along the dorsal side of the right bronchus. During its course, it gives off the arterial branch, running mainly along the lateral or dorsal side of the bronchiole. The left pulmonary artery also runs the same course as in the right lung, and similarly gives off the arterial branch. The pulmonary veins run mainly the ventral or medial side of the bronchiole and between the bronchioles. The right cranial and middle lobe veins form a short common trunk before entering the left atrium. The right accessory lobe vein enters the left atrium, directly. The left cranial lobe vein and one of the left middle lobe veins form a short common trunk before entering the left atrium. The remaining left middle lobe veins enter the left atrium independently. The pulmonary veins in the right and left caudal lobes form the right and left caudal lobe pulmonary venous trunk, respectively. They form a short common trunks before entering the left atrium.
