A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

Background: Ultrashort acting β-adrenergic antagonist, esmolol and local anesthetics, lidocaine are well known about effects of hemodynamic stabilization to tracheal intubation. But, the effects of these drugs are still controversial. The aim of the present study is to assess whether a combination of both drugs are more effective than either drug alone. Methods: Forty eight patients, ASA physical status Ⅰ or Ⅱ, were randomly assigned to one of four groups (n=12 each): control (Group S), esmolol 1 ㎎/㎏ (Group E), lidocaine 1 ㎎/㎏ (Group L) and esmolol-lidocaine combination (Group M). Anesthesia was induced with thiopental 5 ㎎/㎏ intravenously, and then saline, esmolol, lidocaine and combination drug were administered as an intravenous bolus, and immediately followed by succinylcholine 1.5 ㎎/㎏. Tracheal intubation was done 90 seconds after intravenous injection of drugs, respectively. Systolic and diastolic blood pressure and heart rate were measured before induction and every minute for 5 minutes after tracheal intubation. Results: There was a significant attenuation in systolic, diastolic arterial pressure and heart rates after tracheal intubation in esmolol-lidocaine group compared to other three groups. Conclusions: Combination of esmolol 1 ㎎/㎏ with lidocaine 1 ㎎/㎏ seems to be useful for attenuation of the increases in blood pressure and heart rates compare to either drug alone after tracheal intubation.
개 대뇌겉질에서 Platelet-Derived Growth Factor α-Receptor의 출생 후 발달에 관한 면역조직화학적 연구

Background and Objectives : The localization of platelet-derived growth factor-α receptor (PDGF-α R) was commonly restricted to oligodendrocyte progenitors during late embryonic and postnatal development. However, several studies recently demonstrated that mature neurons could also synthesize PDGF-α, Materials and Methods : In the present study, to analyze the distributional pattern of PDGF-αR during postnatal development of the canine cerebral cortex, we used immunohistochemistry on sections of canine brain tissue. Results : We found that neurons of various regions of cerebral cortex exhibited the immunoreactivity to PDGF-αR as early as postnatal day 0, and slightly decreased after postnatal day 14. Whereas neuronal PDGF-αR were maintained at all ages, the oligodendroglia-like expression of PDGF-αR could not be confirmed. Conclusion : The localization of PDGF-αR in immature and mature neurons supports the several roles of PDGF during development, protection and survival of neurons.

Drug induced hiccups may be associated with a various agents, including corticoste-roid, antibiotics, and benzodiazepines. Rarely, levodopa or dopamine agonist therapy in Parkinson’s disease patient, can trigger hiccups. We report a case of persistent hiccup, occurring with dopaminergic medication in a patient with Parkinson’s disease 약물 유발성 딸꾹질은 코르티코스테로이드, 항생제 그리고 벤조디아제핀 등의 약물에 의하여 발생할 수 있다. 드물게 파킨슨병의 치료 목적으로 사용하는 레보도파나 도파민 효현제가 딸꾹질을 유발시킬 수 있다. 저자들은 파킨슨병의 치료 목적으로 레보도파와 도파민 효현제를 사용한 환자에서 조절되지 않는 딸꾹질을 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

This paper presents the future direction of the development and maintenance of the urban park of the Kumi city. The direction was obtained by analyzing the evaluation results on the satisfaction level of park use and the park image of the park users. The analysis results are as follows. 1) It turns out that the rest and accommodation facilities are the major facilities that uplifts the total image of the park. 2) Among the park images, the image on the pleasantness was the major image, related with the satisfaction on the park equipments. 3) The social class, who gave a bad score on the above equipments and images, is a low-aged class, who is a white class with high income as well. Therefore, it is suggested that the park maintenance plan, with emphasis on the class, is an important task.
망막아세포종 세포주(Y-79)의 Arylalkylamine N-acetyltransferase 활성에 미치는 Dopamine의 영향

The arylalkylamine N-acetyltransferase(AA-NAT, EC 2.3.1.87) in vertebral pineal gland and retina is rate-limiting enzyme in the pathway of biosynthesis of melatonin. AA-NAT activities are remarkably increased during night with 10-150 folds. Neurohormone melatonin is thought to play roles in a broad range of physiological functions in human, primarily through effects on the biological clock in the suprachiasmatic nucleus of the hypothalamus, This rhythm reflects large changes in the activities of AA-NAT. So the important regulatory role of AA-NAT has made it central interest in research on melatonin biochemistry and neurochemical signal transduction. The neurotransmitter that regulates the AA-NAT activities is norepinephrine, which acts through a cyclic AMP mechanism. The effect of dopamine on AA-NAT in human retinoblastoma Y-79 cells was studied. the obtained results are as follows; AA-NAT activities in Y-79 cells were increased by cyclic AMP, and dopamine inhibited the AA-NAT activities stimulated by forskolin. The pattern of inhibition of dopamine on the AA-NAT activities in Y-79 cells was time and concentration dependent. The results suggest that dopamine participates in the regulation of the AA-NAT activities through the inhibitory mechanism in the human pineal and retinal tissues.
