A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.

The postmortem stature was measured in 57 Korean adult males (age range: 20-86 years old, mean: 52.3 years old) in supine position. After dissection of the corpses, we measured the maximum length of the remaining limb-bones (humerus, radius, ulna, femur, tibia and fibula). The correlation coefficients between the stature and each limb-bone length were calculated. Simple regression equations for estimating stature from each limb-bone length and multiple regression equations from the combination of limb-bone lengths were also obtained.

Gut microbiota have been known to play an essential role in host immunity and metabolism. Dysbiosis is associated with various gastrointestinal (GI) and other diseases such as cancers, metabolic diseases, allergies, and immunological disorders. So far, the role of gut microbiota has been studied mainly in lower GI disease but has recently been reported in upper GI diseases other than Helicobacter pylori infection, including Barrett's esophagus, esophageal carcinoma, gastric cancer, functional dyspepsia, and non-steroidal anti-inflammatory drug-induced small intestinal mucosal injury. Probiotics have some beneficial effect on these diseases, but the effects are strain specific.

BACKGROUND/AIMS: Esophageal squamous papillorma is a rare benign lesion. This lesion is generally asymptomatic and solitary. Resent studies reveal the presence of human papil- lomavirus in certain cases of esophageal squamous papilloma, and human papillomavirus appears to be pathogenetically related to the esophageal squamous papilloma. The aim of this study was to evaluate the presence of human papillomavirus in esoplmgeal spuamous papilloma. METHODS: In situ hybridizations and direct in situ polymerase chain reactions for human papillomavirus type 6/11 were performed on 16 paraffin embedded tissues with esophageal squamous papilloma. RESULTS: Human papillomavirus type 6/11 was detected in 1 of 16 esophageal squamous papillomas on direct in situ polymerase chain reaction. All lesions were solitary, and 12 of 16 cases were located in distal one-third of the esophagus. Age range was 23-71 years (mean, 41 years). CONCLUSION: These results indicate that causal relation between human papillomavirus type 6/11 and esophageal squamous papilloma is inconspicuous.

PURPOSE: To assess the usefulness of diffusion-weighted imaging(DWI) in evaluating serial parenchymal changesin renal infarction induced by renal artery ligation, by comparing this with the conventional spin echo techniqueand correlating the results with the histopathological findings. MATERIALS AND METHODS: In 22 rabbits, renalinfarction was induced by ligation of the renal artery. Spin-echo T1-weighted imaging(T1WI), turbo spin-echo(TSE)T2-weighted imaging(T2WI), and DWI were performed, using a 1.5-T superconductive unit, at 30 minutes, 1 hour, 2,3, 6, 12 and 24 hours, and 2, 3, 7 and 20 days after left renal artery ligation. Changes in signal intensity onT1WI, T2WI, and DWI were correlated with histopathologic findings. RESULTS: On MR images obtained 30 minutesafter ligation, the signal intensity of affected kidney was not significantly different from that of contralateralkidney, as seen on T1WI and T2WI, but was noticeably higher on DWI. On T2WI, the signal intensity ratio(SIR) wasslightly higher over time from 30 minutes to 2 days after ligation, and then decreased slightly. The SIR on DWIincreased abruptly at 30 minutes, remained high until 12 hours, and then fell, returning to close to the normalrange at between 2 and 3 days. It fell further, below the normal range, until 20 days after ligation. The mainhistopathologic findings after ligation were congestion and swelling of renal tubules (1-6 hours after ligation),degeneration and necrosis of renal tubules (12 hours - 2 days), coagulation necrosis of renal tubules(3 days),collection of cellular debris between renal tubules (7 days), and proliferation of fibroblast between renaltubules (20 days). CONCLUSION: Diffusion-weighted imaging is useful for the detection of hyperacute renalinfarction, and the apparent diffusion coefficient may provide additional information concerning its evolution.

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.

Mayer-Rokitansky-Kster-Hauser Syndrome is characterized by the absence of the vagina and uterus, the presence of apparently normal tubes and ovaries, feminine appeara-nce, normal female secondary sexual characteristics, a normal 46,XX karyotype, and a fem-inine psychosexual orientation. Various methods of surgical treatment have been introduced, but the ideal method is still not found. The two cases reviewed in this paper were all treated with McIndoe operation using full thickness skin graft. Both women were satisfied with vaginal depth and excellent result was achieved. We report two vaginoplasties in patients of Mayer-Rokitansky-Kster-Hauser Syndr- ome including a brief review of literature.

We have previously demonstrated that specific antigens involved in autoimmunity in endometriosis may be endometrial proteins with molecular weight (mw) of 71, 92, and 103 kilodalton (kDa). The purposes of this study were to determine the incidence of IgG antibodies against these endometrial antigens in peritoneal fluid of patients with endometriosis and to evaluate the antigenic differences between the endometria of patients with and without endometriosis. Forty peritoneal fluid (PF) from 24 patients with endometriosis and 16 patients without endometriosis (control patients) were tested against endometrial protein from patients (n=8) with endometriosis and from control patients (n=10) by western blot. Fifteen (62.5%) of 24 PF samples from patients with endometriosis had specific Immunoglobuiin (Ig) G antibodies against one of three endometrial proteins with mw of 71, 92 and 103 kDa but none of PF samples from control patients had these antibodies. The electrophoretic pattern of endometrial proteins from patients with endometriosis was similar to that from control patients. Furthemore there was no significant difference in specific PF Immunoglobulin G binding to endometrial proteins regardless of origin of these proteins. Our data indicate that specific humoral immune response can be found in PF of patients with endometriosis and that specific antigens inducing this immune response are present in human endometrium and that there is no antigenic difference between the endometria of patients with and without endometriosis.
