Abstract

This study was performed to obtain an accurate methods of diagnosis in early stage of traumatic pericarditis and myocarditis in ruminants. Korean native goats were used as experimental animal and traumatic pericarditis and myocarditis were induced by surgical intervention. The changes in clinical signs, hematological values, blood enzymes and electrocardigrams were observed for 14 days after operation. The results obtained were as follows: 1. Body temperature in experimental group of induced traumatic pericarditis and myocarditis was slightly increased than control group that was rumenotomized. Heart rate was increased in both groups but the increased rate was noticed remarkably in experimental group. There was no change in respiratory rate in experimental and control group. 2. Total leucocytes counts and neutrophil percentage maintained higher level after operation and lymphocytes percentage noticed reversed proportion to neutrophil in both groups. 3. Serum total protein concentration and alkaline phosphatase activities after operation showed a little lower levels than these values prior to operation. Serum glutamic oxaloacetic transaminase and lactic dehydrogenase activities in control group showed slight increase through all the experimental period, while in experimental group these activities were markedly elevated and an increase in serum lactic dehydrogenase activities was more remarkable comparing to serum glutamic oxaloacetic transaminase. 4. Electrocardiograms in control group did not show any abnormalities except for slight increase in heart rate. In experimental group the amplitude of QRS complex was increased in duration of experimental period. The transference from QRS complex to T wave was uncertain and S-T segment moved upward obliquely through electrical zero line.
