The present study was conducted to investigate the possible role of the sympathetic nervous system in two-kidney, one clip (2K1C) and deoxycorticosterone acetate (DOCA)-salt hypertension. 2K1C and DOCA- salt hypertension were made in Sprague-Dawley rats. Four weeks after induction of hypertension, systolic blood pressure measured in conscious state was significantly higher in 2K1C $(216{\pm}18\;mmHg)$ and DOCA-salt $(205{\pm}29\;mmHg)$ groups than that in control $(128{\pm}4\;mmHg).$ The third branches (＜300 ${\mu}m$ in outer diameter) of the mesenteric artery were isolated and cut into ring segments of $2{\sim}3$ mm in length. Each ring segment was mounted in tissue bath and connected to a force displacement transducer for measurement of isometric tension. The arterial rings were contracted by application of norepinephrine (NE) in a dose-dependent manner. The amplitude of the NE-induced contraction of the vessels was significantly larger in hypertension than in control. The NE-induced contraction was significantly enhanced by neuropeptide Y (NPY) in hypertension. Reciprocally, NPY-elicited vasocontraction was increased by NE in hypertension. These results suggest that the sympathetic nervous system contributes to the development of 2K1C and DOCA-salt hypertension.

This is a report of three cases of successful embolectomy in peripheral arteries. First case was the patient who received a mitral commissurotomy 8 months ago. In that time, there was no evidence of left atrial thrombosis. He showed an embolism in the middle portion of left brachial artery without complaining of any ischemic pain. Embolectomy was performed 15 days after disappearance of radial pulse and resulted in no return of radial pulse postoperatively. Second case was a case of an embolism in lower portion of right brachial artery. She complained severe ischemic pain and cyanosis in the right forearm and fingers. She was also in the beginning state of cardiac failure, which was suspected from her hypertension associated with cardiomegaly and arrythmia Embolectomy was performed 17 hours after onset of acute pain. Immediate full pulsation of radial artery was obtained after embolectomy and the acute ischemic symptoms subsided gradually. Third case was an embolism in superior mesenteric artery which occured 24 hours after pneumonectomy for right bronchogenic carcinoma and the patient suddenly complained diffuse abdominal colicky pain. 7 hours after attack of abdominal pain. embolectomy with extensive reset ion of the small intestine was performed with uneventful recovery and without complication, such as short bowel syndrome, postoperatively. Histopathologically, the embolus was consisted of a tissue of anaplastic cell carcinoma, which was identical to the tumor of the resected right lung. Histological findings of other emboli of first and second case were old thrombus.

Although laparoscopic pancreaticoduodenectomy (LPD) is considered as minimally invasive surgery, an advanced level of laparoscopic skill is still required. LPD comprises various procedures including reconstruction. Therefore, establishment of a safe approach at each step is needed. Prevention of intraoperative bleeding is the most important factor in safe completion of LPD. The establishment of effective retraction methods is also important at each site to prevent vascular injury. I also recommend the "uncinate process first" approach during initial cases of LPD, in which the branches of the inferior pancreaticoduodenal artery are dissected first, at points where they enter the uncinate process. This approach is performed at the left side of the superior mesenteric artery (SMA) before isolating the pancreatic head from the right aspect of the SMA, which allows safe dissection without bleeding. Safe and reliable reconstruction is also important to prevent postoperative complications. Laparoscopic pancreatojejunostomy requires highly skilled suturing technique. Pancreatojejunostomy through a small abdominal incision, as in hybrid-LPD, facilitates reconstruction. In LPD, the surgical view is limited. Therefore, we must carefully verify the position of the pancreaticobiliary limb. A twisted mesentery may cause severe congestion of the pancreaticobiliary limb following reconstruction, resulting in severe complications. We must secure the appropriate position of the pancreaticobiliary limb before starting reconstruction. We describe the incidence of intraoperative and postoperative complications and appropriate technique for safe performance of LPD.

In cardiovascular disorders, understanding of endothelial cell (EC) function is essential to elucidate the disease mechanism. Although the mouse model has many advantages for in vivo and in vitro research, efficient procedures for the isolation and propagation of primary mouse EC have been problematic. We describe a high yield process for isolation and in vitro culture of primary EC from mouse arteries (aorta, braches of superior mesenteric artery, and cerebral arteries from the circle of Willis). Mouse arteries were carefully dissected without damage under a light microscope, and small pieces of the vessels were transferred on/in a Matrigel matrix enriched with endothelial growth supplement. Primary cells that proliferated in Matrigel were propagated in advanced DMEM with fetal calf serum or platelet-derived serum, EC growth supplement, and heparin. To improve the purity of the cell culture, we applied shearing stress and anti-fibroblast antibody. EC were characterized by a monolayer cobble stone appearance, positive staining with acetylated low density lipoprotein labeled with 1,1'-dioctadecyl-3,3,3',3'-tetramethyl-indocarbocyanine perchlorate, RT-PCR using primers for von-Willebrand factor, and determination of the protein level endothelial nitric oxide synthase. Our simple, efficient method would facilitate in vitro functional investigations of EC from mouse vessels.

To determine whether bile juice exclusion can prevent the mucosal damage, and Insulin-like growth factor-I can promote mucosal regeneration in ischemia-reperfusion injury of the bowel, 39 weanling rats with 10 cm of Thiry-Vella loop were studied. Animal groups were; Control, BL(common bile duct ligation), IGF{insulin-like growth factor-I(IGF-I) infusion} and IGF-BL(combined treatment). IGF-I(1.5 mg/kg/day) was continuously delivered through a subcutaneously implanted miniosmotic pump. After 15 minutes of superior mesenteric artery clamping, a tissue specimen(P) was taken after 30 minutes of reperfusion. Intestinal continuity was restored to allow oral feeding. A specimen of main tract(M) and another of the Thiry-Vella loop(T) were collected for histomorphometry after 48 hours of reperfusion and free feeding. Villus size ratio(VSR), crypt depth(CD), crypt-depth/villus-height ratio(CVR) and injury score(IS) were measured in 15 consecutive villi. The postoperative mortalities of bile duct ligation groups(BL and IGF-BL) were higher than those of other groups. In control group, VSR of M was lower(P<0.05) than P or T, but not in the other groups. VSR of M in control was lower than those in other groups. CD of T in control, IGF and IGF-BL group were higher than those of M. CD of M and T showed gradual increments from control, IGF and IGF-BL group, respectively. CVR of M and T in IGF group were higher than those in control. CVR in IGF-BL group, T was higher than M, and M was higher than P. About IS, M of BL($20.1{\pm}2.5$) and IGF-BL($20.9{\pm}3.3$) groups were significantly lower than that of control($32.4{\pm}2.5$). These results suggest that the exclusion of bile juice reduces the severity of the reperfusion injury of the mucosa, by inability to activate pancreatic enzymes and IGF-I stimulates mucosal regeneration in injured bowel, and the effect is potentiated by bile juice exclusion.

장 폐색의 증상 및 징후가 있는 폐암 환자에서는 원인에 대한 신속하고 적절한 규명이 중요한데 이는 장 폐색의 원인에 따라 치료 방침이 달라지고, 종종 더욱 심한 합병증을 예방하기 위해 응급수술이 필요한 경우도 있기 때문이다. 본 논문에서는 폐암과 동반하여 각기 다른 원인에 의한 장 폐색이 있었던 두 증례를 보고하고자 한다. 첫 번째는 폐암 치료 중 발생한 10 kg의 급격한 체중감소가 있었던 57세 남자로 반복되는 답즙성 구토를 주소로 내원하였다. 전이성 병변은 발견되지 않았으나 전산화단층촬영 및 상부위장관조영술에서 십이지장 제3부의 폐색이 보여 상장간막 동맥 증후군으로 진단되었다. 두 번째 증례는 68세 남자로 3년 전 폐암으로 수술 및 보조항암화학치료를 받았으나 재발하여 경과를 관찰 중이던 환자로 오심, 구토 및 복통으로 내원하였는데 검사 결과 소장 전이로 인한 장 폐색으로 진단되어 수술적 치료를 시행하였다. 폐암 환자에서 장 폐색이 의심될 때 그 원인이 될 수 있는 여러 가능성들을 항상 염두에 두고 진단 및 치료 방침을 세워야 할 것으로 생각된다.
