Osteoporosis represents a reduced amount of bone tissue as compared with controls of same age and sex, and common feature of osteoporosis is a state of skeletal fragility leading to various fractures such as Colles' fracture, vertebral compression fracture, femur neck fracture, generally due to an inadequate amount of normally mineralized bone tissue, making the skeleton incapable of supporting normal mechanical demand. However it is difficult to quantify precisely its magnitude because of the variety of techniques used and the many bone sampling sites concerned. In 1970, Singh and associates(24.25) developed a method for grading the trabecular structure of the proximal end of the femur and reported that the femoral trabecular pattern index can clearly separate persons with osteoporosis from normal individuals. Cameron and its associstes developed an accurste method of determining bone mineral content by means of I-125 photon absorptiometry(5. 28). This method is consistently reproducible at the 98% level and has demonstrated agreement with ash measurement of cadaver bones at the 97% level. A comparative study of the usefulness of the femoral trabecular pattern index(Singh Index) and rsdial bone mineral content measurement by photon absorption was performed in 75 Kroean persons above forty years old. 25 of 75 persons were fracture patients due to osteoporosis. The results were as follows. 1. A significant difference in Singh index was noted between the fracture group snd control group. 2. A significant difference in bone mineral density was noted between the fracture group and control group. 3. A positive correlation was noted between the bone mineral denisty and Singh Index. 4. A significant difference in bone mineral density was noted between the fracture group and the control group which have same grade of Singh Index. So, we believe that bone mineral density is more objective and accurate than Singh Index. 5. We believe that both Singh Index and bone densitometer is useful in diagnosis and grading of osteoporosis.

The occurrence of the small intestinal adenocarcinoma is infrequent and the primary adenocarcinoma of the jejunum is rare. The survival of adenocarcinoma of the small bowel does not improve over the past three decades. Although symptoms appeared to be of long duration, most patients were diagnosed with advanced disease. All reports agree that these tumors are difficult to achieve good examination of the small bowel by both clinician and radiologist, so it cause a significant delay in diagnosis. The survival of these tumors appear to correlate with stage at presentation, and therefore early and aggressive diagnostic intervention seems to improve the outlook. We report a case of primary jejunal adenocarcinoma assoeiated with iron deficiency anemia with literatures review.

Colorectal cancer consists of 8.2 percent of all malignancy in korea, and shows more increaing tendency. Despite the advances in the detection of calorectal cancer no single screening technique has achieved both high degree of diagnostic accuracy and minimal patient morbidity. We studied 24 patients, who underwent colonoscopy, with clinical suspicious colon cancer at Presbyterian Medical Center between Jan and Sep.1995, and evaluated the diagnostic feasibility of colon lavage cytology using oral cleansing solution.(continue...)

PURPOSE: We report seven cases of pancreas transplantation, first performed in Korea, in the context of postsurgical radiologic studies. MATERIALS AND METHODS: All patients with insulin-dependent diabetes mellitus received transplants from cadevaric(n=6) or living related donor(n=1). Retrospective analysis of 27 US(including 19 Duplex US), two CT, four MRi, and three scintigraphy for these patients was made with surgico-pathological correlation in five cases. RESULT:Of the seven patients, three-month graft survival was five and one-year survival was two. One patient died of abdominal abscess following surgery. US gave the valuable informations regarding the graff swelling, vascular complication, and perigraff fluid collection. RBC bleeding scan was effective of the presence or absence and location of intestinal bleeding. CT was useful in determining the extent and severity of the pancreatitis. MRI gave a little information about functional status of the grafted pancreas. CONCLUSION: The choice of appropriate imaging modalities for postsurgical work up in patients who had pacreas transplantation depends on the clinical conditions of the patients and complications suspected. Further prospective studies appear to be necessary to eatablish the interval and modality choice for early detection of the complication.

Toxoplasma gondii is an obligate intracellular protozoan parasite, which invades a wide range of hosts including humans. The exact mechanisms involved in its invasion are not fully understood. This study focused on the roles of Ca2+ in host cell invasion and in T. gondii replication. We examined the invasion and replication of T. gondii pretreated with several calcium modulators, the conoid extrusion of tachyzoites. Calmodulin localization in T. gondii were observed using the immunogold method, and Ca2+ levels in tachyzoites by confocal microscopy. In light microscopic observation, tachyzoites co-treated with A23187 and EGTA showed that host cell invasion and intracellular replication were decreased. The invasion of tachyzoites was slightly inhibited by the Ca2+ channel blockers, bepridil and verapamil, and by the calmodulin antagonist, calmidazolium. We observed that calcium saline containing A23187 induced the extrusion of tachyzoite conoid. By immunoelectron microscopy, gold particles bound to anti-calmodulin or anti-actin mAb, were found to be localized on the anterior portion of tachyzoites. Remarkably reduced intracellular Ca2+ was observed in tachyzoites treated with BAPTA/AM by confocal microscopy. These results suggest that host cell invasion and the intracellular replication of T. gondii tachyzoites are inhibited by the calcium ionophore, A23187, and by the extracellular calcium chelator, EGTA.

We performed a retrospective study of 47 patients(47 eyes) with retinal vein occlusion who had treated with laser photocoagulation for neovascularization from January 1991 through January 1992. Only cases with a minimum of one year follow up were included in this study. The majority of patients were 50 year old(78.7%). Sixteen patients were male(34%) and thirty one patients were female(66%). The proportion of branch retinal vein occlusion and central retinal vein occlusion was 74.5%, 25.5%, respectively. New vessles elsewhere were developed in 36 eyes(76.6%), new vessles on the disc in 7 eyes(14.9%), and 4 eyes(8.5%) had both types of neovascularization. The percents of regression in neovascularization was 72.3% which ranged from 84% for under 10 disc diameter area of retinal ischemia to 64% for over 10 disc diameter area of retinal ischemia. Vitreous hemorrhage occured in 12 eyes(25.5%) within 1 year and especially when ischemic area was over 10 disc diameters and associated with systemic vascular diseases.
