Reflex ileus in acute abdominal disease were produced frequently due to cholecystitis, cholelithiasis, abscess in pelvic, appendiceal and diaphragmatic etc. But we found that a functional type of paralytic ileus due to ureteral stonetr renal stone was commonly seen on the plain roentgenogram. In these functional type of reflex ileus due to urinary stone, distension of the small intestine withgas may interfere with an accurate detection of the stone. It may lead to confusion in detecting ureteral stone and obstructive ileus. In this report, we analyzed how many cases would show a functional type of reflex ileus in urinary stone cases. 1. In 200 cases of urinary stone, reflex ileus with urinary stone were produced in 49 cases(21. 5%) 2. Many cases of ureteral stone were found on lower third of the ureter. (99 cases) 28 reflex ileus cases in 99 cases were produced (29.2%) 3. In reflex ileus due to urinary stone, we classified them by sex, age, location and stone size. The stone was often masked by nausea, vomiting, abdominal distention and reflex ileus on plain roentgenogram. So it is necessary to perform a complete urological study to detect urinary stone.

There are many options for the management of osteoarthritis of the knee joint. Recently, arthroscopic surgery has been added to the armamentorium of the treatment modalities in osteoarthritis of the knee which does not respond to conservative treatment. Among 74 arthroscopic pocedures(including partial menisectomy, removal of loose bodies, synovectomy, cartilage drilling and simple lavage) done for osteoarthritis of the knee, 68 patients studied at average 3.1 years after procedure and the results were as follows 1. Seventy-one percent of patients had at least 2.5 years or more relief of pain and symptoms. 2. Fifty-six percent were still good at follow-up of 3.1 years. 3. The best result were obtained after removal of loose bodies and resection of unstable flap tear of a meniscus in association with mild osteoarthritis. 4. The poor result were obtained in patients with severe degenerative changes of both femoral condyle, 5. The results were much better in the normally aligned knee compared with valgus knee.

PURPOSE: To evaluate the findings and the role of CT in plexiform neuro-fibromatosis of the mediastinum. MATERIALS AND METHODS: We retropectively reviewed the CT scans of five patients with plexiform neurofibromatosis of the mediastinum. The CT scans were reviewed with attention to the distribution of the lesions, appearance and attenuation of mediastinal lesions, enhancement pattern after intravenous contrast infusion and associated findingssuch as intercostal neurofibroma. RESULTS: In all five patients CT scans demonstrated fusiform low attenuated masses which were oriented longitudinally and extended over multiple contiguous scans along the distribution of major mediastinal nerves. In four patients, mediastinal lesions appeared infiltrative, obliterating adjacent mediastinal fat plane. One patient had well defined fusiform masses along the major mediastinal nerves. Postcontrast enhanced CT scans revealed slight central enhancement in two patient and no contrast enhancement in three patients. Associated findings such as neurofibromas of intercostal nerves and sympathetic trunk, or subcutaneous neurofibromas were detected on CTscans in all five patients. CONCLUSION: Characteristic CT findings of low attenuation masses along the major mediastinal nerves are helpful to differentiate plexiform neurofibromatosis from mediastinal lymphadenopathy and to prevent from misreading as a malignant disease.

Cases of metastases from extracranial tumor to intracranial tumor are very rare. The world wide review of the literatures until 1992 revealed 44 cases of primary intracranial tumors containing metastatic tumors which are unrelated extracranial primary malignant tumors; the intracranial recipient tumor is a meningioma in 35 cases among them. Carcinomas of the lung and the breast are the most common extracranial donor tumors. Metastases from colon cancer to meningioma are extremely rare. A 74 year-old-female presented with headache for 2 weeks. CT revealed a round mass with high signal intensity, measuring 4 cm in diameter, which is located in the left parietal lobe. The patient had colon cancer 2 years ago and lymphoma I year ago. On operation, the tumor is relatively well delineated and attached to the meninx. Microscopically, the tumor is composed of fascicles of long slender, fibroblast-like spindle cells with indistinct cytoplasmic border, variable amount of collagen deposit and many psammoma bodies. A few scattered glands are present in periphery of the meningioma. The tumor glands are composed of columnar cells with basally located hyperchromatic nuclei and similiar to the glands of the adenocarcinoma of the colon.

STATEMENT OF PROBLEM: In cases where bony defects were present, guided bone regenerations have been performed to aid the placement of implants. Nowadays, the accepted concept is to isolate bone from soft tissue by using barrier membranes to allow room for generation of new bone. Nonresorbable membranes have been used extensively since the 1980's. However, this material has exhibited major shortcomings. To overcome these faults, efforts were made to develop resorbable membranes. Guided bone regenerations utilizing resorbable membranes were tried by a number of clinicians. Bio-Gide. is such a bioresorbable collagen that is easy to use and has shown fine clinical results. PURPOSE: The aim of this study was to evaluate the histological results of guided bone regenerations performed using resorbable collagen membrane(Bio-Gide.) with autogenous bone, bovine drived xenograft and combination of the two. Surface morphology and chemical composition was analyzed to understand the physical and chemical characteristics of bioresorbable collagen membrane and their effects on guided bone regeneration. MATERIAL AND METHODS: Bioresorbable collagen membrane (Bio-Gide.), Xenograft Bone(Bio-Oss), Two healthy, adult mongrel dogs were used. RESULTS: 1. Bioresorbable collagen membrane is pure collagen containing large amounts of Glysine, Alanine, Proline and Hydroxyproline. 2. Bioresorbable collagen membrane is a membrane with collagen fibers arranged more loosely and porously compared to the inner surface of canine mucosa : This allows for easier attachment by bone-forming cells. Blood can seep into these spaces between fibers and form clots that help stabilize the membrane. The result is improved healing. 3. Bioresorbable collagen membrane has a bilayered structure : The side to come in contact with soft tissue is smooth and compact. This prevents soft tissue penetration into bony defects. As the side in contact with bone is rough and porous, it serves as a stabilizing structure for bone regeneration by allowing attachment of bone-forming cells. 4. Regardless of whether a membrane had been used or not, the group with autogenous bone and Bio-Oss. filling showed the greatest amount of bone fill inside a hole, followed by the group with autogenous bone filling, the group with blood and the group with Bio-Oss. Filling in order. 5. When a membrane was inserted, regardless of the type of bone substitute used, a lesser amount of resorption occurred compared to when a membrane was not inserted. 6. The border between bone substitute and surrounding bone was the most indistinct with the group with autogenous bone filling, followed by the group with autogenous bone and Bio-Oss. filling, the group with blood, and the group with Bio-Oss. filling. 7. Three months after surgery, Bio-Gide. and Bio-Oss. were distinguishable. CONCLUSION: The best results were obtained with the group with autogenous bone and Bio-Oss. filling used in conjunction with a membrane.

We present a 37-year-old male who was found to had mas within the bronchus. This patients was admitted for the evaluation of cough. Chest CT scan showed endobronchial mass in the bifurcation of LUL and LLL bronchus. The left lower lobe was atelectatic. Lobectomy of the left lower lobe was done. On opening of the bronchus, there was a 2x1x1 cm sized endobronchial mass. Histologically, the mass was smooth muscle tumor composed of densely packed eosinophilic spindle cells in interlacing bundles with pale elongated nuclei covered by bronchial epithelium. On immunohistochemical staining, the tumor cells were positive for desmin. Ultrastructurally, the tumor cells exhibited numberous cytoplasmic microfilaments with focal densities, pinocytotic vesicles, and a thick basal lamina.

Heat shock protein(HSP), first found in the MCF-7 human breast tumor cell line is one of the estrogen-regulated proteins and its synthesis is stimulated by estradiol. In this study, immunohistochemical staining was done for estrogen receptor(ER) and HSP on formalin-fixed, paraffin-embedded tissue sections in twelve normal cyclic and twenty carcinomatous endometria. 1) During the proliferative and early secretary phases, the nuclei of surface and glandular epithelial cells and stromal cells had moderate to strong staining for ER, whereas during the mid and late secretary phases, the glandular epithelial and stromal cells had weak staining for ER. The surface epithelial cells had positive staining of variable intensity. 2) From the early proliferative to mid secretary phases, the glandular and surface epithelial cells showed a positive reaction of variable intensity for HSP. In the late secretary phase, the glandular and surface epithelial cells showed a weak positive or a negative reaction for HSP. During the menstrual cycle, the stromal cells remained negative for HSP. 3) In adenocarcinomas of the endometrium, 8 of 11 (72.7%) well differentiated carcinomas were positive for both ER and HSP, while only 3 of 9(33.3%) moderately and poorly differentiated carcinomas were positive for ER and HSP. In conclusion, ER and estrogen-regulated heat shock protein(HSP) were closely related in normal and carcinomatous endometria and the reactivity was decreased according to poor differentiation.
