  • 정상인에서 Guanethidine Nicardipine Nitroglycerine Prostaglandin $E_1$을 피하주사하고 지속적인 복사열을 주사한 후에 Pain Meter NYT-5를 이용하여 동통역치를 측정하였다. 통증역치는 Guanethidine과 Nicardipine에 의해 상승되었으며 Nitroglycerine에 의해서는 거의 변화가 없고 Prostaglandin $E_1$에 의해서는 감소되었다. 이러한 변화는 지각신경섬유의 말단 감각수용체에 대한 감수성이 이들 혈관확장제에 대하여 서로 다른 작용을 나타내는것 같다.

  • A 70-year-old male came to the emergency room of the authors' hospital because of sudden cardiac arrest due to inferior wall ST elevation myocardial infarction. His coronary angiography revealed multiple severe coronary spasms in his very long left anterior descending artery. After an injection of intracoronary nitroglycerine, his stenosis improved. The cardiac arrest relapsed, however, accompanied by ST elevation of the inferior leads, while the patient was on diltiazem and nitrate medication to prevent coronary spasm. Recovery was not achieved even with cardiac massage, intravenous injection of epinephrine and atropine, and intravenous infusion of nitroglycerine. The patient eventually recovered through high-dose nicorandil intravenous infusion without ST elevation of his inferior leads. Therefore, intravenous infusion of a high dose of nicorandil must be considered a treatment option for cardiac arrest caused by refractory coronary vasospasm.

  • A 2-month-old female Abyssinian cat was presented with a severe ascites, cyanosis, and exercise intolerance. Diagnostic studies revealed V/VI holosystolic murmur, sinus tachycardia, generalized cardiomegaly with marked left atrial enlargement and shunt flow between left and right ventricles. Doppler study showed bi-directional shunts in rest and right-to-left shunt after exercise. Based on clinical signs and diagnostic findings, the cat was diagnosed as a reversed ventricular septal defect. The cat was treated with furosemide, nitroglycerine, dobutamine and oxygen supplement. Despite initial improvement of clinical signs after initiation of medical treatment, the cat died of sudden cardiac arrest. Necropsy revealed a perimembranous ventricular septal defect.

  • A 17-month-old intact male Cocker Spaniel was presented with primary complaints of severe ascites, exercise intolerance, and diarrhea. Diagnostic studies revealed tricuspid and pulmonic regurgitation on phonocardiogram, right ventricular enlargement on the electrocardiogram, typical right cardiac enlargement signs on the thoracic radiography and tricuspid valve malformation and marked enlargement of the right atrium and right ventricle on the echocardiography and tricuspid and pulmonary regurgitation on the color spectral echocardiography, suggesting tricuspid valve dysplasia and pulmonary hypertension. Using angiography and cardiac catheterization, pulmonary hypertension was ruled out. Further echocardiographic study revealed membranous valvular structures cranial to pulmonary annulus causing pulmonary regurgitation. Based on these findings on the diagnostic investigation, the case was diagnosed as tricuspid valve dysplasia complicated with pulmonic regurgitation. The dog was medically managed with furosemide, enalapril, nitroglycerine transdermal patch and pimobendan after the ascitic fluid removal.

  • A propellant mainly consisting of nitric ester including nitrocellulose and nitroglycerine is characteristic of being decomposed naturally. And this phenomenon is known as being affected mostly by its storing temperature and humidity. In this research, the effect of storing temperature and humidity on self life has been studied by measuring the contained quantity of residual stabilizer of propellant KM30Al, which are parts of 155MM propelling charge K676 and K677; the method for the measurement is acceleration aging test, and decomposition reaction equation, Eyring Equation and Berthlot Equation were used for the calculation. As result of this study, it was found that the storing temperature influenced seven times as large as the storing humidity upon the self life of the propellant KM30Al, Furthermore, especially in the high temperature region, the storing temperature had a dominant effect on the self life.

  • A propellant mainly consisting of nitric ester including nitrocellulose, nitroglycerine and nitroguanidine is characteristic of being decomposed naturally. And this phenomenon is known as being affected mostly by its storing temperature. In this research, the effect of storing temperature on self life has been studied by measuring the contained quantity of residual stabilizer of propellant KM30A1, ignition powder and combustible cartridge case, which are parts of 155MM propelling charge K676 and K677; the method for the measurement is acceleration aging test, and decomposition reaction equation and Berthlot Equation were used for the calculation. The result of this research shows that propellant KM30A1, ignition powder, combustible cartridge case in order of decreasing self life, and the self life decreases to 1/3 as the temperature increases by $10^{\circ}C$.

  • An approximately 8-month-old, 2.61 kg, male Siamese kitten was referred with primary complaints of a 1-week history of respiratory distress, exercise intolerance and dyspnea. Diagnostic studies identified III/VI systolic murmur in the cardiac auscultation, right ventricular enlargement patterns in the electrocardiogram, pleural effusion and right-sided cardiomegaly in the thoracic radiography, and right marked ventricular dilatation, right atrial enlargement, atrial septal defect and abnormal left atrium divided by fibromuscular membrane. Based on these findings, the case was diagnosed as cor triatriatum sinistrum complicated with an ostium primum atrial septal defect. The cat was rescued with furosemide, nitroglycerine, oxygen supplement and fluid removal from pleural cavity.

  • The thermal decomposition of waste energetic materials such as TNT, RDX and composition B in a commercial rotary kiln has previously been carried out. As part of the demilitarization process, the thermal decomposition of homogeneous double base propellant (DB) used in M8 and consisting predominantly of nitrocellulose and nitroglycerine is examined with respect to a number of operating conditions. A single condensed phase reaction with 4 species and 365 gas phase reactions and 59 species are considered. Simulation results show the sensitivity of the thermal decomposition of DB with temperature and velocity. At relatively low velocity with constant inlet hot air temperature, temperature in the rotary kiln was found to be highest, 953 K and 1300 K for cases 3 and 6 respectively. Illustrating that optimum operating temperature can be achieved by controlling the inlet velocity without additional cooling systems.

  • A 9-month-old, female Miniature Pinscher(MP) dog weighing 1.97kg was presented because of periodic syncopal episode for 5 months. This case was diagnosed as primary dilated cardiomyopathy based on respiratory distress history, weak femoral pulse, generalized cardiomegaly, pulmonary edema, marked dilation of left atrium(LA) and left ventricle(LV), decreased wall thickness of LV and interventricular septum(IVS), increased EPSS in echocardiography, and young age of onset in the absence of other cardiovascular disorders. The patient was stabilized by application of diuretics(Furosemide, 2 mg/kg, SC, q 1 hr) and venodilator(Nitroglycerine patch, 0.5 mg/kg, q 12 hrs). Clinical signs were improved with medical management of positive inotropic vasodilator(Pimobendan, 0.2 mg/kg, PO, q 12 hrs) and angiotensin-converting enzyme(ACE) inhibitor(benazepril, 0.5 mg/kg, PO, q 12 hrs), potassium gluconate gel(2 mEq/dog, PO, q 12 hrs) and, L-carnitine(50 mg/kg, PO, q 12 hrs). The dog still maintains stable clinical status 10 months after the first visit. We report the rare case of DCM in small breed dog, which corresponds to the diagnosis and treatment of typical DCM in large breed dog.
