Background: The lumbar sympathetic ganglia are variable in both position and numbers. The aim of this study was to detect the appropriate lumbar vertebral level where the lumbar sympathetic ganglia primarily aggregate. Methods: Forty patients comprising of hyperhidrosis (26 cases), complex regional pain syndrome (10 cases), peripheral artery occlusion disease (3 cases) and postherpetic neuralgia (1 case) underwent lumbar sympathetic block. We randomly selected one of two (L2 or L3) levels and the L4 level. The position of the needle tip and distribution of dye was verified by injection of a mixture of radio-opaque dye (1.5 ml) and 4% lidocaine (1.5 ml) and subsequently confirmed by L-spine anteroposterior and a lateral view X-ray. We considered the response positive when the skin temperature increased more than $1^{\circ}C$ in 5 min. Results: In general, the positive response ratio was greater when the needle tip located at the L2 or L4 level vice L3 and when the drug was distributed on the lower half of the L4 body and in the L4/5 intervertebral disc space. In a right side block, the positive response ratio was greater when the drug was distributed on the lower half of the L4 body and in the L4/5 intervertebral disc space, although in a left side block there was no significant difference seen between the levels. The complications of the neurolytic block were alcohol neuritis (7.5%) and hypoesthesia (5%) on the L1 or L2 dermatome. Conclusions: The best effect with least chance of complication may be induced by spreading the drug on the lower half of the L4 body and/or into the L4/5 intervertebral disc space by placing the needle tip on the L4 body.

Background: Stellate ganglion block (SGB) might be associated with changes in the blood pressure (BP) and heart rate (HR). The heart rate variability (HRV) shows the balance state between sympathetic and parasympathetic activities of the heart. The changes in these parameters of the HRV were studied to evaluate the possible mechanism of SGB in changing the BP. Methods: SGB was performed on 26 patients, using a paratracheal technique at the C6 level, and 8 ml of 1% mepivacaine injected. The success was confirmed by check the Horner's syndrome. The BP, HR and HRV were measured before and 5, 15, 30, 45 and 60 minutes after the SGB. Results: The increases in the BP from the baseline throughout the study period were statistically, but not clinically significant. The HR and LF/HF (low frequency/high frequency) ratio were increased at 5 and 45 min, respectively, after the administration of the SGB. In a comparison of left and right SGB, no significant differences were found in the BP, HR and HRV. A correlation analysis showed that an increased BP was significantly related with the changes in the LF/HF ratio and LF at 15 and 30 minutes, respectively, after the SGB. Dividing the patients into two groups; an increased BP greater and less than 20% of that at the baseline INC and NOT groups, respectively, hoarseness occurred more often in the INC group (P = 0.02). Conclusions: It was concluded that SGB itself does not clinically increase the BP and HR in normal hemodynamic patients. However, the loss of balance between the sympathetic and parasympathetic nerve system, attenuation of the baroreceptor reflex and hoarseness are minor causes of the increase in the BP following SGB; therefore, further studies will be required.

Dopamine transporter concentrations have been known to decrease in Parkinson's disease (PD) or increase in Tourette's disorder. The purpose of this study was to evaluate the effectiveness of [I-123]N-(3-iodopropene-2-yl)-$2{\beta}$-carbomethoxy-$3{\beta}$-(4-chlorophenyl) tropane (IPT) as an imaging agent for measuring changes in transporter concentrations with PD. IPT labelled with 6.69+/-0.64 mCi(247.53+/-23.68 MBq) of I-123 was intravenously injected into ten patients(age: 55+/-11) with PD, and six normal controls(NC)(age: 46+/-14) as a bolus. Dynamic SPECT scans of the brain were then performed for 5 minutes each over 120 minutes on a triple headed camera. Time activity curves were generated for the left basal ganglia(LBG), right basal ganglia(RBC), and occipital cortex(OCC). The statistical parameters included the time to peak activity, the contrast ratio of LBG and RBG to OCC at several time points, and the accumulated specific binding counts/mCi/pixel(ASBC) from 0 to 115 minutes. The uptake of IPT in the brains of PD and NC peaked within 10 minutes of injection in all subjects. The maximum target to background ratio in the basal ganglia of PD and NC occurred at 85+/-20 min and 110+/-6 min of injection, respectively. The BG/OCC ratios at 115 minutes for PD and NC were 2.15+/-0.54 and 4.26+/-0.73, respectively. The ASBC at 115 minutes for PD and NC were 152.91+/-50.09 and 289.51+/-49.00, respectively. The ratio of BG/OCC for the NC was significantly higher than the ratio for PD. SPECT data matched with clinical diagnosis for PDs. The ratio between BG and OCC and the ASBC for PD were clearly separated from NC and may be useful outcome measures for clinical diagnosis. The findings suggest that IPT may be a very useful tracer for early diagnosis of PD and study of dopamine reuptake site.

Background: The purpose of this study was to evaluate whether measuring the ratio of descending aortic enhancement (DAE) to main pulmonary artery enhancement (MPAE) on pulmonary computed tomography angiography (PCTA) can predict poor outcome in patients with acute massive or submassive pulmonary embolism (PE). Methods: We retrospectively, reviewed computed tomgraphy findings and charts of 37 patients with acute PE and right ventricular dysfunction. We divided the enrolled patients into 3 groups; group Ia (n=8), comprised of patients with major adverse event (MAE); group Ib (n=5), consisted of those with PE-related MAE; and group II (n=29), those without MAE. We analyzed the right ventricular diameter (RVD)/left ventricular diameter (LVD) and DAE/MPAE on PCTA. Results: For observer 1, RVD/LVD in group Ia ($1.9{\pm}0.36$ vs. $1.44{\pm}0.38$, p=0.009) and group Ib ($1.87{\pm}0.37$ vs. $1.44{\pm}0.38$, p=0.044) were significantly higher than that of group II. For observer 2, RVD/LVD in group Ia ($1.71{\pm}0.18$ vs. $1.41{\pm}0.47$, p=0.027) was significantly greater than that of group II, but RVD/LVD of group Ib was not ($1.68{\pm}0.2$ vs. $1.41{\pm}0.47$, p=0.093). For both observers, there was a significant difference of DAE/MPAE between group Ib and group II ($0.32{\pm}0.15$ vs. $0.64{\pm}0.24$, p=0.005; $0.34{\pm}0.16$ vs. $0.64{\pm}0.22$, p=0.004), but no significant difference of DAE/MPAE between group Ia and group II ($0.51{\pm}0.3$ vs. $0.64{\pm}0.24$, p=0.268; $0.53{\pm}0.29$ vs. $0.64{\pm}0.22$, p=0.302). Intra-class correlation coefficient (ICC) for the measurement of DAE/MPAE (ICC=0.97) was higher than that of RVD/LVD (ICC=0.74). Conclusion: DAE/MPAE measured on PCTA may predict PE-related poor outcomes in patients with massive or submassive PE with an excellent inter-observer agreement.

배경: 폐장의 허혈-재관류 손상은 폐이식에서 발생하는 조기 이식장기 실패의 주요 원인의 하나로 알려져 있다. 최근 갑상선 호르몬의 활성형인 삼요드티로닌 (T3)이 심장을 비롯한 여러 장기의 허혈 손상을 줄여주는 효과가 있음을 시사하는 보고가 있다. 본 연구에서는 이러한 T3의 허혈-재관류 손상에 대한 효과가 폐장의 허혈 손상에도 효과가 있을 것으로 기대하고 덱스트란을 주성분으로 하는 세포외액성 폐보존액에 T3를 추가한 새로운 폐보존액을 제조하여 그 효과를 검증하고자 하였다. 대상 및 방법: 12마리의 황견을 6마리씩 두 군으로 나누어 제 1군에서는 새로 개발한 폐보존액을 사용하고, 제 2군에서는 유로콜린스 용액을 사용하여 폐를 적출 하였다. 적출한 폐장은 각각의 보존액에 담그어 섭씨 4도에서 20시간 보관한 후, 각 군에 6마리씩 총 12례의 좌측 폐이식을 시행하였다. 이식된 좌측폐만의 기능을 관찰하기 위해서 폐이식 후 재관류를 15분시킨 후에 우측 주폐동맥과 우측 주기관지를 결찰하고, 2시간 동안 혈역학적 변수와 가스분석을 시행하고, 측정이 종료된 후 바로 희생하여 폐조직 일부를 떼어내어 조직검사와 수분 함량 및 MDA양을 측정 비교하였다. 결과: 동맥혈 산소분압은 제 1군에서 재관류 후 60분, 90분 120분에 각각 147$\pm$25 mmHg, 148$\pm$22 mmHg, 159$\pm$21 mmHg, 제 2군에서는 각각 133$\pm$26 mmHg, 132$\pm$29 mmHg, 135$\pm$30 mmHg로 제 1군에서 조금 높은 경향을 보였으나 통계적으로 유의성은 없었다. 각 시간에서의 최대 흡기압은 제 1군에서 14.0$\pm$0.5 cmH2O, 14.2$\pm$0.6 cmH2O, 15.7$\pm$0.8 cmH2O, 제 2군에서는 17.8$\pm$2.0 cmH2O, 18.0$\pm$1.9 cmH2O, 19.3$\pm$2.7 cmH2O으로 제 1군에서 조금 낮은 경향을 보였으나 통계적 유의성은 없었다. 동맥혈 이산화탄소 분압은 제 1군에서 각 시간에 27.9$\pm$2.2 mmHg, 27.7$\pm$2.4 mmHg, 28.0$\pm$3.0 mmHg, 제 2군에서는 36.8$\pm$6.0 mmHg, 43.2$\pm$8.1 mmHg, 53.1$\pm$17.4 mmHg로 제 1군에서 유의하게 낮았다 (p<0.05). 폐혈관 저항 및 조직 MDA양은 두 군간에 유의한 차이가 없었다. 폐 조직 수분 함량은 제 1군에서 유의하게 낮았고, 조직학 검사상 폐조직 손상의 정도도 제 1군에서 적었다. 결론: 이상의 결과에서 T3를 포함한 새로 개발한 폐보존액이 유로콜린스 용액과 비교하여 폐보존능이 우수함을 확인할 수 있었고, 이는 T3가 폐이식시 폐장의 효과적 보존에 유용한 역할을 함을 시사하였다.

Three dogs with suspected patent ductus arteriosus were referred to Veterinary Medical Teaching Hospital of College of Veterinary Medicine, Konkuk University because of cough, shortness of breath, exercise intolerance, and syncope, Continuous murmur and thrill were detected in physical examination. Left ventricular enlargement, cardiomegaly, bulged main pulmonary artey were found in radiography. Tall R wave, wide P wave, atrial fibrillation, and turbulent flow were observed in electrocardiogram and echocardiogram. Thoracotomy was performed at left fourth intercostal space under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. The median (mean ${\pm}$ SD) diameter of patents was $8.0{\pm}2.0mm$. The median operation time was $36{\pm}6.6min$. On examination right after surgery, continuous murmur, thrill, atrial fibrillation, and turbulent flow were disappeared. On 30 days after surgery, clinical signs, left ventricular enlargement, and, bulged main pulmonary artery were disappeared. VHS 12.5 and 13.5, R wave 3.3 and 3.0 mV, and P wave 0.05 and 0.05 sec were decreased to 10.0 and 10.5, 1.8 and 2.0 mV, and 0.04 and 0.04 sec respectively in case 1 and 2. Ratio of aorta and main pulmonary artery in diameter was changed 1 : 1.3 and 1 : 1.6 into 1 : 1.1 and 1 : 1 respectively in case 1 and 2. Mild tear developed during dissection in case 3 and hemorrhage was controlled by vascular Devakey forceps. However, the dog died. On 12 months after surgery, patients (case 1 and case 2) have not showed abnormal signs.

본 기초연구에서는 강제수영검사(forced swimming test, FST)에 의해 우울증이 유발된 쥐의 해마(hippocampus) 부위에서 뇌 대사물질(brain metabolites)중에 choline 신호의 변화를 관찰하였다. 본 연구의 목적은 우울증이 유발된 쥐에 항우울제인 desipramine-HCl을 투여하여 정상 쥐와 약물을 투여한 쥐 사이의 뇌 대사물질의 차이를 자기공명분광법(magnetic resonance spectroscopy: MRS)을 통하여 알아보는 것이다. 실험대상으로는 6주령의 SD rat을 사용하였으며 우울증을 유발시키고 항우울제의 약물평가를 위한 모델링 방법으로 강제수영검사를 시행하였다. 자기공명분광법을 시행하기 위한 localization 방법으로는 PRESS 펄스시퀀스를 사용하였다(TR: 2,500 ms, TE: 144 ms, averaging: 512, complex data point: 2048, scan time: 25 min). 정상 쥐 그룹과 우울증을 유발시킨 뒤 항우울제를 투여한 쥐 그룹 모두 양쪽 해마부위에서의 NAA/Cr, Cho/Cr 비율(ratio)은 차이가 나지 않았다. 또한 왼쪽 해마에서 정상 쥐와 항우울제를 투여한 쥐 사이에서 NAA/Cr, Cho/Cr 비율도 차이가 나지 않았고, 오른쪽 해마부위에서도 통계적으로 유의한 차이가 없었다. 본 연구를 통하여 anti-immobility효과를 나타내는 항우울제를 투여함으로써 choline 신호가 정상 쥐와 비슷하게 회복되는 것을 관찰하였다. 이는 앞으로의 항우울제 약물 평가에 있어 자기공명분광법을 도입함으로써 기존의 주관적인 판단을 배제할 수 없었던 행동변화분석만으로 항우울제의 효과를 평가하는 방법에 비해 객관적이고 정량적인 분석을 할 수 있다는 점에서 아주 유용한 방법이라 사료된다.
