BACKGROUND: We examined whether puromycin aminonucleoside (PAN)-induced nephrotic syndrome (NS) is associated with altered renal handling of water and sodium along with changes of renal abundance of aquaporins (AQP1 and AQP2) and NHE3. Next we tested the effects of alpha-melanocyte stimulating hormone (alpha- MSH), a potent anti-inflammatory drug, on the PAN-induced renal functional derangement and the changes of renal AQPs and NHE3 abundance. METHODS: PAN was administered to Sprague-Dawley rats using two protocols: protocol 1 (180 mg/kg, single iv injection) and protocol 2 (100 mg/kg, single iv injection). RESULTS: In both protocols, PAN-induced NS was associated with decreased urine concentration, manifested by an increased urine output and decreased urine osmolality and TcH2O. Consistent with this, a marked downregulation of vasopressin-regulated collecting duct AQP2 expression was seen in PAN-induced NS. In protocol 2 where rats treated with moderate dose of PAN, alpha-MSH cotreatment prevented the reduction of urine osmolality and the increase of the FENa in the PAN-induced NS. This suggests that alpha-MSH may have protective effects against the renal functional deterioration induced by PAN. The renal abundance of the AQP1, AQP2 and NHE3 was reduced in PAN-induced NS in protocol 2, as seen in protocol 1. In contrast to the functional improvement, alpha-MSH cotreatment had marginal effects in the prevention of renal AQP1, AQP2 and NHE3 downregulation in PAN-induced NS. CONCLUSION: PAN-induced NS was associated with decreased urine concentration along with reduced renal AQP2, AQP1 and NHE3 abundance. Alpha-MSH may have protective effects against the renal functional deterioration (e.g., urine osmolality and FENa). However, alpha-MSH treatment alone is less likely to prevent the marked reduction of AQP2, AQP1 and NHE3 abundance in PAN-induced NS, in contrast to the previously known dramatic effects against the ischemia-reperfusion injury in kidney and small intestine.

The study was undertaken to asses the changes in the size and densities of intracranial hematomas by analyzingthe sequential CT examination of 23 patients ar Soon Chun Hyang College Hospital from July '80 to Aug. '81. Theresuls were as follows; 1. The high densities of hematoma were the cause of hematoma, hematoma locaiton, age andsex of patients, and initial hematoma size. 3. The CT findings that indicate complete absorption of hematomas werenormalization of mass effect, not diappearence of hematoma densities. 4. In intracerebral hematoma, the highdensity of hematoma reduced it's density and mass effect about 4-6 weeks duration. 5. In subdural hematoma, about7 weeks after head trauma, the CT findings were normalized.

Cystic parathyroid adenoma is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. This type of adenoma tends to cause increased serum level of parathyroid hormone and alkaline phosphatase, similar serum calcium level when compared to those of solid adenoma. Thanks to current radioimmunoassay and easy accessibility to serum autoanalyzer, serum calcium level and parathyroid hormone level are more easily measured, which in turn lead to more easier diagnosis of hyperparathyroidism. Also improvement in imaging and nuclear diagnostic method of parathyroid lesion are suggested to enable easy diagnosis of cystic parathyroid adenoma. A 35-year-old male presented with easy fatigability for 12 months. The serum calcium, phosphate, alkaline phosphotase were 11.5mg/dL, 1.4mg/dL, 194IU/L respectively and his parathyroid hormone level in serum was 126.42pg/mL. Neck CT showed enlargement of right lobe of thyroid gland with well defined inhomogenously enhanced density inside the right thyroid gland. The patient was diagnosed of hyperparathyroidim due to parathyroid adenoma and was surgically removed. The surgical biopsy showed cystic parathyroid adenoma. After operation his general condition was improved and serum calcium, phosphate, parathyroid hormone level were normalizd. We report a case of hyperparathyroidism caused by cystic parathyroid adenoma with brief review of literature.

PURPOSE: To clarify the chracteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. MATERIALS AND METHODS: We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. RESULTS: The tumors included 33 lipomas, 11 hemangiomas. 11 lymphangiomas, 7 neurilemmomas, 4 epidermold cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The SOhographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxoma), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and chacteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymphangioma. Neurilemmoma showed Iobulated, oval to round, relatively hypoechoic mass with or without internal cystic portion. CONCLUSION: Sonographic evaluation of benign soft tissue tumros is useful in demonstrating the location, size, extent, and internal characteristics of the mass. A relatively confident diagnosis can be made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging.

Involucrin is a recently recognized structural component of mature squamous epithelial cells and is considered as a marker of normal eratinocyte differentiation and ma.turation. In this study peroxidase-antiperoxidase techniques were used to assess involucrin expression in histologic sections of normal skin and a variety of epidennal tumors including squamous cell carcinomas(25 cases), keratoacanthomas(11 cases), basal cell carcinomas(20 cases), trichoepitheliomas(5 cases), Howens diseases(12 cases), arsenic keratoses(10 cases), actinic keratoses(10 cases) and Pagets diseases(2 cases). The results were as follows : l. In normal skin, the upper third of the viable epidermis showed diffuse cytoplasmic staining for involucrin. In hair follicles, the lower area of inner root sheath and inner area of the outer root sheath stained positively. The sebareous glands did not stain, but the ducts of sebaceous glands were positive. 2. Keratoacanthomas showed a relatively homogeneous staining pattern for inirolucrin ', all cells except basal cells stained with mild to moderate intensity. In contrast, squamous cell carcinomas disclosed a highly irregular involucrin staining pattern with marked variation in staining intensity from cell to cell. 3. Basal cell carcinomas were negative for involucrin except squamous horn cysts, and the epidermis overlying basal cell carcinomas showed the field effect, that is, the epidermis overlying the tumors exhibited diffuse, homogeneous positive staining of cells in all layers of the epidermis. 4. ln trichoepitheliomas, the involucrin reactivity was negative as in basal cell carcinoma.s, but the field effect was not observed. 5. In Elowens disease, actinic keratosis, arsenic keratosis and Pagets disease, the positivit.y for involucrin staining extended deeper into the stratum malpighii than was observed wit,h normal epidermis. And areas showing irregular patchy pattern of involucrin staining were considered to have the potentiality of malignant invasive change much more than the negative or homogeneous areas. Paget's cells were negative for involucrin as the adjoining keratinocytes in the lower portion af epidermis.

Three-dimensional solid model has not been widely used in surgical prediction of orthognathic surgery because freque from occlusal restorations or prosthesis limited the usefulness of simulated surgery involving occlusion. We prepared three-dimensional(3D) solid model from CT data and integrated the 3D solid model with dental cast using a face-bow transfer technique combined with skeletal reference measurement and confirmation with cephalometric radiographs. With this simple and easy method, it was possible to predict bony interference between the proximal and distal segment of the mandible so that we can prevent condylar displacement after sagittal split ramus osteotomy of the mandible with prominent asymmetry. The method error was within 2mm and it seemed to be useful in preoperative planning for maxillofacial surgery with maxillo-mandibular occlusal change

It is difficult to know whether the presence of infection in the plantar ulcer in patients with leprosy or not. Because routine bacteriology is often unhelpful, we need to investigate diagnostic method in this situation. C-reactive protein(CRF) levels have been known to be useful in detecting infection in some diseases. In this study, CRP levels were measured in 20 leprosy patients with plantar ulceration and 14 patients with leprosy alone. The results were as follows : 1. There was no elevation of CRP levels in patients with leprosy alone, and in the majority of patients with ulcers. 2. Of 20 patients with plantar ulcers, four had raised CRP levels one had clinically obvious infection, and three had erythematous skin of uncertain cause surrounding their ulcers. 3. Treatment with an appropriate antibiotics reduced CRP levels to normal, which was associated with clinical improvement. Therefore, it is suggested that increased CRP levels can be a useful probe for detecting significant bacterial infection in plantar ulcers of leprosy patients.
