A rare case in the pattern of the origin of the celiac artery was observed in the cadaver of a 64 year old Korean male and the results are summarized as follows. The superior mesenteric artery originated from the abdominal aorta at the level of the intervertebral dusk between first and second lumbar vertebra. At a point 4cm from the origin of the superior mesenteric arterr, a common trunk appeared and ran 1cm and then divided into the common hepatic artery and the splenic artery. The common hepatic artery divided into the right gastric artery and the proper hepatic artery at a point 4.5cm after the bifurcation. A common trunk formed by the left inferior phrenic artery and the lefts gastric artery arose from the abdominal aorta about 0.8cm about the origin of the celiacomesenteric trunk.

PURPOSE: Recently developed BMS(TM) (Zassi Bowel Management System(TM): Hollister Inc., Illinois, USA) can provide effective nonsurgical fecal diversion without the risks associated with colostomy creation and subsequent closure. Our aim is to evaluate the effectiveness of the BMS in diverting feces from the perianal wide surgical wound in patients with Fournier's gangrene. METHODS: BMS(TM) was applied in five patients (male: 2, median age; 44) with Fournier's gangrene from January 2000 to September 2001. The treatments consist of three times a day wound dressing after wide surgical debridement and intravenous antibiotic therapy. For evacuation of feces, twice daily warm saline irrigation was administered via BMS(TM) or low daily doses of polyethylene glycol solutions were orally taken in. An endoscopic and anorectal manometric study was done to evaluate possible mucosal complications and anorectal functional changes. RESULTS: The average duration of the BMS application was 41 (range, 22~63) days. The result of a manometric study after immediate removal of the BMS(TM) showed a decreased mean resting pressure (range: 22~36 mmHg) and a decreased mean squeezing pressure (range: 32~39 mmHg). After 3 days, the sphincter pressure had improved markedly: mean resting pressures of 38, 45, 60, and 63 mmHg and mean squeezing pressure of 78, 89, 91, and 101 mmHg respectively. Fecal incontience was not noted in any patient. Other possible mucosal complications were not noted. There were no mortalit. CONCLUSIONS: BMS(TM) application in Fournier's gangrene patients after surgery successfully avoids a defunctioning colostomy. Furthermore, no significant complications were noted over a prolonged period up to 63 days.

Changes in the number, the immunoreactivities and the ultrastructures of sero- tonin immunoreactive mucosal mast cells[MMCs] in rat gastrointestinal tracts after vagus nerve stimulation were investigated by using light and electron microscopic immunocytochemical methods. The vagus nerves were electrically stimulated with a square wave pulse generator for a duration of 5 minutes each, a total of 8 times at 2 minute intervals. Serotonin immunoreactive cells of the connective tissues of the gastrointestinal tract were mainly located in the lamina propria, and a small number of the cells were also scattered in the submucosa. By using electron microscopic immunocytochemistry and Wright stain, the serotonin immunoreactive cells of the lamina propria and the submucosa were identified to be MMCs. A few large-sized serotonin immunoreactive connective tissue mast cells [CTMCs], showing strong metachromasia with the Wright stain, were located together with the MMCs in the submucosa of the stomach. In most of the gut regions of the control group, the majority of the MMCs did not show any serotonin immunoreactivities and only a few MMCs showed weak serotonin immunoreactivities. After stimulation of the vagus nerves, the number and the immnu- noreactivities of the serotonin immunoreactive MMCs dramatically increased in all gut regions observed, especially in the small intestines. In the samples treated with the electron microscopic immnunocytochemical methods, hardly any serotonin immunoreactivities were detected in the MMCs of the control group. However, the serotonin imrnunoreactivities of the MMCs were significantly increased after vagus nerve stimulation. The serotonin immnunoreactive products were localized, following vagal stimulation, both in the peripheral matrix of the granules and in the cytoplasm. Also, it was confirmed ultrastructurally that the Golgi complexes were expanded in the MMCs of the vagal stimulation group. The above results suggest that vagus nerve stimulation may activate serotonin biosynthesis in MMCs.

This study was undertaken to investigate the ultrastructure of the neurons, neuroglial cells and capillaries in the area postrema[AP] of the Oriental discolured bat, Vespertilio superans. The AP of the bat was a single midline structure at the most caudal portion of the fourth ventricle. Most neurons in the AP were small cells, but their ultrastructure were similar to the typical neurons located elsewhere in the central nervous system. Astroglial cells and oligodendrocytes were also observed and showed their typical ultrastructure. Ultrastructural features of neurons, astroglial cells and oligodendrocytes were not changed during hibernating cycles. However, microglial cells were only found in the hibernating AP ; these cells were located in the parenchyma and near the blood vessels of the AP. Since the microglial cytoplasm was filled with phagocytotic inclusions, the nuclei of the these cells were eccentrically located. Phagocytotic cytoplasmic inclusions were shown to be composed of a dense irregular peripheral region and the pale round central region. A Large vacant space was often found in the electron lucent central region. Continuous and fenestrated capillaries surrounded by pericytes were found in the bat`s AP. Especially, Phagocytotic inclusions were found in the pericyte cytoplasm of the hibernating AP, and this result supports suggestion that pericytes might be phagocytotic cells. On the basis of the distributions of phagocytotic tells[pericytes and microglial cell], ultrastructure of these cells, morphology of their cytoplasmic inclusions, and the appearance of phagocytotic activity of the pericytes during the hibernating stage when microglial cells were observed, it can be concluded that pericytes may also participates in the formation of rrlicroglial cells. Tanycytes were also found in the bat AP.

Presyrinx consists of reversible spinal cord swelling without frank cavitation, as observed on T2 weighted magnetic resonance imaging (MRI). The condition may evolve into syringomyelia, but timely surgical interventions have achieved meaningful results. Here, we report the case of a 27-year-old woman who presented with headache, dizziness, and diplopia 2 months after suffering a mild head trauma. On MRI, hydrocephalus, downward herniation of the cerebellar tonsil, and a diffuse high signal change in the cervical spinal cord were detected. After insertion of a ventriculoperitoneal shunt, her neurological symptoms resolved, and she has had no signs of presyrinx recurrence for >4 years.
