PURPOSE: Microangiography is an experimental radiologic technique for evaluation of the morphology and the function of small vessels. The purpose of this study is to introduce a good microangiographic technique and to present the microangiographic appearance of normal hepatic vascular pattern. MATERIALS AND METHODS: Five white rabbits weighing 2.5-2.9Kg were objected. Polyethylene catheters were inserted in portal vein and then in IVC. Heparin mixed normal saline (2cc/1000cc) was infused through portal vein and blood was drained to IVC. Barium suspension was infused via the catheter placed in portal vein untill the liver surface showed satisfactory finding in barium filling. The liver was removed and this preparation was fixed in 10% formaline for 7 days. After fixation, the liver was sectioned on 1-2mm thickeness. The slices were radiographed on high resolution plate using Faxitron. H-E staining of liver tissue was also done. RESULTS: The microbrium was well distributed in all small vessels without filling defect. And we could find the hexagonal shaped classic liver Iobule, in which the central vein was located at central portion and portal vein at periphery. The enlargement was showed numerous sinusoids, but there was less dye in the central portion of Iobule, but the central vein was well filled by microbarium. The peripheral portion of Iobule was well filled with microbarium. So, we could find diamond shaped liver acinus, in which central vein was located at priperal portion and the center of liver acinus was terminal portal vein that growed out from a small portal space. The three acini made the complex acinus and acinar agglomerate was composed of three or four complex acini. CONCLUSION: It is considered that the liver acinus pattern of Rapparport is more acceptable on microangiography than the classic concept of hepatic Iobule.

OBJECTIVE: This study has been carried out to evaluation the effect of fertilization promoting peptide (FPP) on the kinematic parameters, capacitation and acrosome reaction of the frozen-thawed human spermatozoa. METHODS: After FPP treatment, we examined kinematic parameters, capacitation and acrosome reaction, using the methods of computer-aided sperm analysis (CASA) and chlortetracycline (CTC) fluorescence analysis. RESULTS: We have obtained the evidence that FPP can promote the capacitation and inhibit the spontaneous acrosome reaction of frozen-thawed human spermatozoa in vitro. Fpp (25~100 nM) induced a significant increase in the proportion of B-pattern capacitated spermatozoa, and a significant decrease in the proportion of F-pattern uncapacitated ones without significant stimulation of acrosomal exocytosis. In the kinematic parameters treatment, FPP treated groups maintained higher LIN, BCF and STR than those of control. The VAP, VSL, VCL and ALH were not different. Therefore it is suggested that FPP in human seminal plasma may play a positive role in promoting human sperm function.

The seroepidemiologic studies on anti-Toxoplasma antibody titers were carried out using ELISA and indirect latex agglutination test. Among 899 sera prepared from pregnant women, 39 cases (4.3%) revealed positive reaction and 218 sera from middle school students showed 4 positive reaction (1.8%) by ELISA. By LAT(newly established by National Veterinary Research Institute, Korea), the sera of 7 pregnant women (0.8%) showed positive reaction. When 80 sera showing +S1:8 by LAT were used for comparing the results obtained from LAT and Toxotest-MT (Eiken Chemical Co., Japan), 7 cases and 8 sera were positive, respectively. All of 11 sera of proven toxoplasmosis patients showed positive reaction in both tests. Overall proportion of agreement between LAT kit and Toxotest-MT was 0.94( -index= 0.632, p<0.01), and LAT was considered to be useful for the screening of toxoplasmosis.

Splenic artery pseudoaneurysms can be caused by pancreatitis, trauma, or operation. Traditionally, the condition has been managed through surgery; however, nowadays, transcatheter arterial embolization is performed safely and effectively. Nevertheless, several complications of pseudoaneurysm embolization have been reported, including coil migration. Herein, we report a case of migration of the coil into the jejunal lumen after transcatheter arterial embolization of a splenic artery pseudoaneurysm. The migrated coil was successfully removed by performing endoscopic intervention.

Erdheim-Chester disease is a rare non-Langerhans-cell histiocytosis involving bones and multiple organs. Its clinical course can vary, from an asymptomatic state to a fatal disease, with renal involvement being a common cause of death. A 41-year-old man presented with a 10-month history of bilateral lower limb pain. Left perirenal soft-tissue infiltration had been found incidentally two years earlier. No progression of the lesion or deterioration of renal function was observed for a period of two years. At admission, plain radiography and magnetic resonance imaging of the patient's lower limbs showed patchy osteosclerosis. Biopsy of the tibia revealed histiocytic infiltration, which was found to be positive for CD68 and negative for CD1a. This report describes an unusual case of Erdheim-Chester disease involving a stationary course of disease with no specific treatment for a long period of time.

OBJECTIVES: Bisphosphonate is the primary cause of bisphosphonate-related osteonecrosis of the jaw (BRONJ). Bisphosphonates are eliminated from the human body by the kidneys. It is anticipated that bisphosphonate levels in the body will increase if the kidney is in a weak state or if there is systemic disease that affects kidney function. The aim of this study was to analyze the relevance of renal function in the severity of BRONJ. MATERIALS AND METHODS: Ninety-three patients diagnosed with BRONJ in Pusan National University Dental Hospital from January 2012 to December 2014 were included in this study. All patients underwent a clinical exam, radiographs, and serologic lab test, including urine analysis. The patient's medical history was also taken, including the type of bisphosphonate drug, the duration of administration and drug holiday, route of administration, and other systemic diseases. In accordance with the guidelines of the 2009 position paper of American Association of Oral and Maxillofacial Surgeons, the BRONJ stage was divided into 4 groups, from stage 0 to 3, according to the severity of disease. IBM SPSS Statistics version 21.0 (IBM Co., USA) was used to perform regression analysis with a 0.05% significance level. RESULTS: BRONJ stage and renal factor (estimated glomerular filtration rate) showed a moderate statistically significant correlation. In the group with higher BRONJ stage, the creatinine level was higher, but the increase was not statistically significant. Other factors showed no significant correlation with BRONJ stage. There was a high statistically significant correlation between BRONJ stage and ‘responder group’ and ‘non-responder group,’ but there was no significant difference with the ‘worsened group.’ In addition, the age of the patients was a relative factor with BRONJ stage. CONCLUSION: With older age and lower renal function, BRONJ is more severe, and there may be a decrease in patient response to treatment.

A benign metastasizing pulmonary leiomyoma (BMPL) is a rare disease that usually occurs in women with a prior or coincident history of uterine leiomyoma. Although leiomyoma is histologically benign, it has the potential to metastasize to a distant site such as the lung. A 35 year old woman who had undergone a hysterectomy due to uterine leiomyoma 5 years prior was admitted for an investigation of multiple pulmonary nodules on a routine chest roentgenogram. An open lung biopsy was taken to make a pathological diagnosis. The microscopic finding of the nodules was leiomyoma and was similar to those of the uterine leiomyoma that had been resected 5 years ago. The woman underwent wedge resections of all pulmonary nodules. This is the first case of BMPL in Korea, which was treated with wedge resections of all multiple pulmonary nodules.

BACKGROUND: Doxylamine is the most commonly intoxicated drug in the emergency room. This drug is relatively safe but is known to induce rhabdomyolysis and acute renal failure in rare occasions. We found the presence of microscopic hematuria in doxylamine intoxicated patients. But no previous studies have documented this hematuria. Our objectives of this study were to determine the incidence of microscopic hematuria after doxylamine overdose and to find the prognostic factors that contribute to this complication. METHODS: This study was conducted from 22 patients admitted to Kyung Hee Medical Center after doxylamine intoxication during the period from January 2001 to December 2003. Using the protocol made beforehand, the amount ingested, past history and laboratory results were recorded. Rhabdomyolysis was defined as serum myoglobin over 300 ng/mL or serum creatine phosphokinase (CK) over 1, 000 IU/L. Data were analyzed using SPSS program with t- test, Fisher's exact test and discriminant analysis. RESULTS: The microscopic hematuria was detected in 63.6% of patients. The amount ingested per body weight, presence of rhabdomyolysis and the time when the muscle enzymes reach highest level were related to the hematuria. CONCLUSION: The incidence of microscopic hematuria was higher when more than 30 mg per body weight of doxylamine was ingested than less this amount. Microscopic hematuria suggests the presence of kidney and urinary tract injury. Urine pH of hematuria is over 7.5. Our findings provide no support for the belief that the ferrihemate injures the kidney of doxylamine ingested patients.

Achalasia is a motility disorder of the esophagus consisting of abnormal relaxation of the lower esophageal sphincter and aperistalsis of the esophageal body. Esophageal dilatation and bird beak appearance are characteristic radiologic findings of achalasia, but achalasia patients do not always show typical findings on esophagography. We recently experienced a 38-year-old female patient who complained of chest pain and dysphagia. She showed no dilatation of the esophagus with delayed emptying of the contrast media in esophagography, but achalasia was diagnosed by typical manometric findings. The patient's symptoms improved after a balloon dilatation. Therefore, esophageal manometry should always be performed when the patient's history suggests the presence of achalasia without typical radiologic findings. We report this case with a review of the literature.
