Collagenous colitis is an uncommon condition charaeterized clinically by diarrhea and weight loss and histologically by thickening of the subepithelial collagen band with chromic inflammation. Laboratory tests of blood, urine and stool, and colonscopic findings are usually normal. The etiology of collagenous colitis is unknown. We report a case of collagenous colitis improved after treatment with sulfasalazine with review of literatures.

This study analyzed 88 patients who sustained a cervical spine injury during the past 4 years(Jan, 1993-May, 1996) in whom had 33 anterior, 21 posterior interventions were underwent and 34 remaining patients recieved conservative treatment with halovest. In 45 cases of upper cervical injuries, 16 operations were done. Among these, anterior approach was used in 3 patients and posterior approach in 13 patients. In 43 cases of lower cervical injuries, 39 operations were done. The anterior approach was used in 30 patients, posterior approach in 9 patients, and bilateral approached in remaing 4 cases. For patients with a predominent posterior ligamentous or osteoligamentous lesion, we selected anterior approach, when closed reduction was possible. Whenever the facet joint remained interlocked, a posterior approach was chosen. This report does not mentioned priority of anterior procedure at any case. Although clinical experience does not support the experimental data, we examined the reliability of anterior approach with use of internal fixation.

We observed the gastric varices in l89 variceal patients with liver cirrhosis and in 129 patients with UGI bleeding by endoscopy. Gastric varices was found in 27 cases(14.2%) amoag 189 variceal cases. There was variceal bleeding in 74 cases(57.4%) beieg the toy cause of UGI: bleeding among l29 cases with UGI bleeding and 6(4.7%) had endoscopically proved gastric Variceal bleeding. Cardiac and fundic varices were observed in l8 and 12 cases, respectively end 12 cases of cardiac varices were mainly observed on the lesser curvature side. The incidence of isolated gastric varices being 30 % amoag gastric varices was far less than that of esophagogastric varices. There was no significant relations between the severity of liver cirrhosis and the kinds of varices These results suggest that gastric varices are not infrequent cause of UGI bleeding cases. Therefore all must have attention in gastric intestinal fiberscopic examination in portal hypertensive patients.

The following is the authors' case report of a 24-year-old man with solitary osteochondroma on the C1 posteior arch. The patient experienced an acute onset of cervical cord compression symptome after rotation injury. Cervical magnetic resonance imaging and cervical computed tomography reveald extensive extradural cervical spinal cord compression. As a result surgical removal of osteochondroma was performed. Osteochondroma is a rare cause of spinal pathology and neurological dysfunction. The above case of cervical osteochondroma with spinal cord compression is reported and the patholgical, clinical and radiological features are discussed with brief review of the literature.

We managed a 27-year-old woman, who suffered from a type II odontoid fracture, with a halo-vest. After 12 weeks, we confirmed bony fusion on cervical spine CT and managed her with a neck collar. During the OPD follow up, we checked the cervical spine film every 1 month. After two and half months, displaced odontoid process was noted on routine cervical film, and a bony gap was found at the previous fracture wite on cervical spine CT. There is only one report in the literlature describing a nonunion after radiographically confirmed healing of a type II odontoid fracture. We report this case in order to emphasize the importance of scheduled follow up examination and evaluate precipitating factors of delayed nonunion of odontoid fracture.

Angiodysplasia as a cause of gastrointestinal bleeding is increasingly recognized with the advancement of diagnostic technique. Most of angiodysplasia occur in old age and their sizes rarely exceed a few millimiters in diameters. Angiodysplasia of the gastrointestinal tract in young adult and adolescent is a very rare cause of gastrointestinal bleeding and thought to be a distinct clinicopathologic entity. We experienced a case of angiodysplasia in young man with chronic upper gastrointestinal bleeding and iron deficiency anemia required periodic red blood cell transfusion. It is a very rare case that angiodysplasia involved entire stomach and total gastrectomy was necessary to manage chronic bleeding.

Background: Endoscope-assisted surgery is a surgical method that has been used in oral and maxillofacial surgical fields. It provides good illumination, clear, and magnified visualization of the operative field. The purpose of this article is to describe the early clinical experiences to conduct minimally invasive surgery with endoscope-assisted enucleation of cysts on the jaw. It appears that this approach may be a superior alternative to the conventional approach. Methods: In this study, 24 patients (9 females, 15 males, average age 41.5) underwent endoscope-assisted cyst enucleation under general anesthesia. All operations were done by one surgeon. The cases were classified depending on whether bone penetration occurred at the cyst site. The cystic lesions were enucleated using an endoscope with a 0°, 1.9 mm diameter, or a 30°, 2.7 mm diameter. Two bony windows were used for the insertion of a syringe for irrigation, curettes, suction tips, sinus blades, surgical drills, and an endoscope. An additional small channel was made for the insertion of endoscopic instruments. Results: The 24 patients who underwent cyst enucleation were regularly observed for 3 to 12 months to evaluate for complications. Although some patients experienced swelling and numbness, these symptoms did not persist, and the patients soon returned to normal and there was no sign of recurrence. Conclusions The results of this study have suggested the possibility of minimally invasive surgery with endoscopes when it comes to cyst removal in the oral and maxillofacial region. Nevertheless, this study has limitations designed as a preliminary report focusing on the feasibility of endoscope-assisted cyst enucleation in the oral and maxillofacial regions.

Symptoms of basal rot occurred sporadically on creeping bent grasses growing at a golf course in Hampyeong, Korea in April 2007. Ten isolates of Microdochium sp. were obtained from leaves and crowns of the diseased bent grasses. All isolates were identified as Microdochium bolleyi based on morphological, cultural, and molecular characteristics. This is the first report on M. bolleyi associated with basal rot on creeping bent grass in Korea.

This study investigated the morphological differences of P. ostreatus grown in the artificial environmental conditions such as humidity, temperature, ventilation, and watering. Oyster mushroom, which was cultivated on artificial environmental condition, was shown to have different morphology of fruitbodies. The optimum CO2 concentration for good morphology of P. ostreatus was 0.3%. But most fruitbody showed the morphologically low qualities in more than 0.5% of CO2 concentration. In the humidity in excess of 80% at 13~16degrees C, the best morphology of P. ostreatus was investigated. The growth of fruitbodies of P. ostreatus in the ventilation system was good at the wind velocity ranging from 0.2~0.5 fpms and expouring type. In other conditions, P. ostreatus generally showed the morphology closing to malformation.

This study investigated the biochemical changes of abnormal fruiting bodies grown under artificial environmental conditions in P. ostreatus. Abnormal mushroom growth during cultivation damages the production of good quality mushroom. This study showed that different environmental conditions produced morphological changes in the fruiting bodies of P. ostreatus. The fruiting bodies with morphological changes were collected and examined for differences in biochemical properties, enzyme activities, and carbohydrates composition. The enzyme activities assay showed that glucanase and chitinase activities decreased when the temperature was below or above the optimum cultivation temperature for P. ostreatus. The biochemical compositions of the abnormal mushroom were significantly different from the normal fruiting bodies. It was suggested that the changes in the biochemical composition of abnormal mushroom were caused by the unfavorable environmental conditions during mushroom cultivation.
