In order to analyze the number and length of the renal arteries and to evaluate abnormalities of the renal parenchyme and vessel digital subtraction angiogram images of 105 potential renal donors(45 men and 60 women aged 17-66 years) were studied retrospectively. For the entire series 31 donors had multiple renal arteries on one side (15 on the left 11 on the right) and 5 donors on the both sides. 89 donors were family related either paents or siblings of recipients. The estimation of the length of the renal artery was based on the mean height of the second lumbar vertebral body(L2) the right renal artery is significantly loner than on the left and measured more than the height of L2 vertebral body in 84 cases on the right and 60 cases on the left. twenty two dnors underwent right nephrectomy dut to presence of multiple renal arteries on the left (N=14) proximal bifurcation of left main renal artery (N=3) and young females in reproductime age(N=5) Unexpected abnormalities found with angiogram were seen in 7 cases and they include renal artery stenosis (N=2) renal cysts (N=4) and focal were seen in 7 cases and they include renal artery stenosis (N=2) renal cysts (N=4) and focal infarction (N=1) In cases of the renal cysts and focal infarcation. there were no serious complications related to the abnomalities. It is concluded that intra-arterial digital subtraction angiography is safe and efficient method to image renal anatomy of the potential renal donors.

Ulcerative colitis(UC)is a disease that affects the mucosal lining of the colon. Epidemiologlcal studies revealed that UC is global in distribution and the incidence has risen in recent decades. The pathogenesis of UC, remains uncertain. However, recent studies have suggested that colonic environment, most notably bacteria flora, genetic susceptibility, mucosal defects, immunologic abnormalities, altered levels of specific cytokine and inflammatory mediators,and dietary factors are implicated. The major symptoms of ulcerative colitis include diarrher, abdominal pain, and hematochezia(rectal bleeding). Ulcerative colitis also may be complicated by many local and systemic disorders as extracolonic symptoms. Erythema nodosum is one of the most frequent dermatologic complications associated with ulcerative colitis. It is an acute, painful, rective skin inflammation of unknown cause. Physicians can disgnose clinically, since there is no accepted histological diagnostic criteria. Conventational therapy is preferred to control causative disease. We authors experienced a case of suppurative erythema nodosum on both shins of ulcerative colitis patient, which was treated with high dose corticosteroids and discharged with clinical improvement of dematologic manifiestation, coincidently controlled acute exacerbation of the bowel disease. So we report this case with a brief literature review.

Thorium-234 (Th-234; t(1/2) = 24.1 days) has been widely used as a tracer of particle settling and organic carbon export in the ocean. However, the use of Th-234 in the ocean has been hampered by labor-intensive procedures, low throughputs, and large uncertainties related to source impurities. Here, we demonstrate a more efficient technique developed to analyze Th-234 in seawater by modifying the traditional Fe(OH)(3) co-precipitation method. The advantages and shortcomings of this method were compared with the Th-234 analytical method using MnO2 precipitation. In the new method, following the equilibration of the Th-230 spike with Th-234, Th was co-precipitated with Fe. Although the precipitates include a fraction of U, Fe precipitation was fast, and the supernatant can be easily siphoned off, allowing simple handling of several samples simultaneously. The Th adsorbed onto particles, collected by Fe precipitation, was desorbed in similar to 4 M HNO3 solution by heating at 230 degrees C for 30 min in a sealed Teflon bottle. Then, Th was separated from U using UTEVA resin. The counting source of Th was prepared by micro-precipitation of Ce. We were able to process similar to 60 samples for 5 days onboard, and the first counting was completed within a week upon returning to the laboratory. The main advantages of this method include (1) easy increase in the sample volume, (2) rapid Fe precipitation, (3) high-purity Th sources for beta and alpha counting, (4) no need for mass spectrometry, and (5) the high throughput.

We report a case of tsutsugamushi disease in a 26 year-old pregnant woman who was treated with azithromycin. Her gestation period was 27 weeks and she admitted with fever, rash, and eschar on the right shoulder. Currently recommended medications for the treatment of scrub typhus are doxycycline or chloramphenicol. But, these drugs are class D drugs according to the U.S. Food and Drug Administration (FDA) Fetal Risk Summary, so they couldn't be used to treat pregnant women. Recently, a few case reports suggested that azithromycin, a relatively new macrolide antibiotic, was effective and safe for the treatment of scrub typhus in pregnant women. And, there is no evidence that azithromycin causes harmful effects to the developing fetus or to children. On the basis of current in vivo test that confirms the effectiveness of azithromycin, it may be the drug of choice for the treatment of scrub typhus in pregnant women and children.

The superficial spreading type of early gastric cancer has usually been defined as an early gastric cancer in which the product of the longest diameter and the diameter perpendicular to it was greater than 25㎠. Although the superficial spreading type of early gastric cancer is histologically aggressive compared with those without such histological aggressiveness, the 5 year survival rate is as good as a non-superficial spreading types of early gastric cancers if the wide surgical resection with extensive lymph node dissection is performed as a treatment. We experienced a case of superficial spreading early gastric cancer in a 59-year-old man. This case is reported with a brief review of related literature.

The most common developmental anomaly of midgut rotation and fixation is non-rotation. Symptomatic intestinal malrotation is relatively common in infants and children but uncommon in later ages. Most adult cases are silent throughout life and are not discovered unless they cause acute or chronic abdominal pain. Many such patients have ill-defined abdominal complaints and are labeled as having a “functional” disorder since no definite clinical abnormalities are found other than the subjective complaints. The most frequent symptomatic presentation in the adult is midgut volvulus the symptom of which is usually self-limited although often recurrent and sometimes leading to an abdominal catastrophe. The diagnostic means for the adulthood malrotation include simple and contrast radiographic studies and CT scan. Malrotation first detected by cholescintigraphy is rare. We report a case of intestinal non-rotation incidentally discovered on DISIDA hepatobiliary scintiscan.

Doubts about effectiveness of CA19-9 are arsing since CA19-9 may show false positive with increase in blood in such cases of not only malignant tumor, but also acute cholangitis caused by gall stone or biliary obstuction. In such case, it is helpful in differentiating from malignant tumor to adjust the standard level of CA19-9 higher up to 300U/ml, or to reexamine after treament of initial acute inflammation or drainage of bile caused by biliary obstuction. The patient of 64-year-old female whose chief complaints were epigastric pain, fever and chilling sensation. The AST/ALT was 100/120 IU/L and alkaline phosphatase was 325IU/L and her initial level of Ca19-9 was 1,522U/mL and showed a significant increase. On ultrasonography and ERCP there was diffuse dilatation of common bile duct and intrahepatic duct without luminal obstruction. Conservative treatments and antibodics treatment for acute inflammation was applied reexamination thereafter showed the decreased and normal CA19-9 level of 22.4U/mL and liver function test.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant inherited disease characterized by telangiectasias of the skin, mucous membranes, and various organ system. HHT is not unusual in western countries but there were several reported cases of HHT in Korea. Recently we evaluated a 40-year-old postpartum female who had been suffering from recurrent epistaxis and peripartum dyspnea. The patient was diagnosed as a HHT complicated by high output heart failure caused by intrahepatic arteriovenous malformation. This case is reported with a review of relevant literature.(Korea J Hepatol 2000;6:514-518).

Mucinous cystic neoplasms of the pancreas are rare primary tumors. They are low-grade tumors that occur predominantly in middle-aged woman. They usually arise within the tail of the pancreas and manifest as large, multiloculated cystic masses. In most cases, they are confined to the tail or body of the pancreas. All mucinous cystic neoplasms should be considered as mucinous cystadenocarcinomas of low-grade malignant potential. Complete surgical excision alone results in an excellent clinical outcome. We experienced a case of mucinous cystadenocarcinoma of the pancreas with invasion to the spleen in a 66-year-old woman. The mucinous cystadenocarcinoma involving the spleen is extremely rare and there has been no case report in Korea. Distal pancreatectomy and splenectomy was performed. It was concluded that multiloculated cyst developed from pancreatic tail and manifested as a huge splenic cyst. We report this rare case with a review of literature.(Korean J Gastroenterol 2001;38:453-456)

김지우,심훈섭,임이진,김태진,정진영,조경호,김태완,박지수,양은진,Chen Xiaoyu,서호종 한국해양과학기술원 2023 Ocean science journal Vol.58 No.3

Trace metals generally exist at very low concentrations (pM–nM) in seawater, and could function as nutrients, contaminants, and tracers of various oceanographic processes. However, collection of seawater samples for a trace metal analysis without contamination is difficult because they exist ubiquitously. We present a detailed trace-metal-clean seawater sampling system that has been constructed on the ice-breaking research vessel (IBR/V) Araon. This sampling system consists of commercially available components without custom fabrication to minimize costs. The system consists of a polyurethane-coated aluminum rosette frame, 12-L Teflon-coated Niskin-X samplers, nonmetallic rope, and autofiring module that enables an automatic bottle firing. Using this system, seawater samples were collected in the Ulleung Basin, East Sea (Japan Sea), and the concentrations of dissolved trace metals (Mn, Fe, Cu, Zn, Cd, and Pb) were analyzed. Comparisons of trace metal concentrations to those obtained from the normal sampling system and previous data showed that our clean seawater sampling system could be utilized without metal contamination.
