The clinical state with EEG pattern similar to interval discharge of epileptics is named as latent epilepsy, which does not necessarily mean that the patient will develop epilepsy later. However, since there is possibility of developing epilepsy on later date, antiepileptic mainly dilantin was tried to control the abnormal EEG. Since January to October 1985, total 580 headache cases with more than moderately abnormal EEG visited the Neurology Clinic. Among them 162 cases with interval seizure pattern (ISP) of epilepsy were selected for the study. The main ISP was 1. diffuse theta and/or delta bursts and 2. spikes. Since the study in only analysis of clinical treatment of 162 cases without previous planning based on financial aid, about 30% of the patients did not return after the 1st EEG examination, in 42% failed to follow the EEG after the treatment and only remaining 28% of the cases were studied. Among 29 patients who were treated with Dilantin 100mg tid po, 16 improved and 13 not. Of the 13, 4 showed partial improvement and partial progression. Case1. In 4 weeks of antiepileptic therapy (AR), spikes disappeared but in 2 months developed bursts. Case2. In 17days of AR, spikes and bursts disappeared but in 3 months bursts reccured. Case3. In 1 week of AR, bursts disappeared but spikes developed. Case4. In 3 months of AR, no change of spikes and bursts and she discontinued the AR. In 6 months she developed grandma seizure. Eighteen cases, treated with other drugs except antiepileptics, all showed improvement. The other drugs were vincaprol, polygammalon, aronamin, ATP and hydergine. The improved cases had spikes more often than theta bursts. In view of the small number of the cases due to dropping most patients out of present study, it is considered meaningless to perform statistical analysis. Further well planned study with more patients is to be expected.

The objective of the present study was to identify the characteristics of phospholipase C (PLC) isozymes purified from bovine brain and to investigate their interrelationship with G protein. The purified PLC isozymes β, γ and δ were obtained and the characteristics of PLC activity on various concentrations of free Ca²⁺ were observed. The activity of PLC was increased with increasing Ca²⁺ concentration and the activity PLC δ was increased higher in the presence of phosphatidyl choline (PC) than in the absence of PC. For vesicle formation as the structure of cell membrane, cholic acid and deoxycholic acid as detergent on phosphatidylinositol bisphosphate (PIP₂) substrate containing PC were used, and then the activity of PLC isozymes were increased with increasing concentration of cholate, from 0.2% to 1% and were increased slightly in deoxycholate. In the PIP₂ containing phospholipid and glycolipid as brain extract, the activity of PLC isozymes were checked in 0.2-1% cholic acid. The activities of PLC isozymes were continuously increased up to 1% cholic acid. The quantitation of PLC isozymes from several bovine organs by radioimmunoassay was made. Brain was the most sufficient organ in terms of amount of PLC β and δ. A large amount of PLC δ was existed in adrenal gland. The binding capacity of GTPrS and G protein was observed and other observations of the binding effect of GTPrS-G protein and PLC monoclonal Ab-Protein A from tissue homogenate with PLC were made. From the observation the binding capacity was revealed the range of 0.11-1.49%. The effects of each type of G protein on the percent activity of purified PLC isozymes were observed. From the observation, activities of isozymes were increased in Goa & Gmix, and the activities of PLC β and δ were increased in Gβγ and Gia. Activities of PLC β and γ were decreased in Gta but PLC δ increased.

Renal vein thrombosis is usually a complication of multiple underlying renal disease rather than primary process. High incidence of renal vein thrombosis in patients with nephritic syndrome, which suggest the nephrotic syndrome play a paramount role in the genesis of renal vein thrombosis or thromboembolic phenomena. But these are likely to relationship of “egg and chicken”, and then we cannot determine what is primary of these. Recently authors experienced a case that was questioned renal vein thrombosis with nephrotic-syndrome clinically, laboratory and preliminary radiologically, and this case in confirmed by selective left renal venography. Here we report a case of renal vein thrombosis with nephrotic syndrome which successfully managed with oral anticoagulants and reviewed literatures.

Computed tomographic findings in fifteen cases of anterior mediastinal teratoma are presented and comparedwith radiographic , pathologic findings. Specific CT characteristics of anterior mediastinal teratoma arepredominantly fatty mass with a denser dependent element and globular calcification in a solid protuberance intothe cystic cavity. Six cases presented above described characteristic CT findings. Four cases presented waterdensity mass with surrounding thick wall. Fat and calcific densities were present in nine and seven respectively,so these findings are frequently absent. Thick wall was present in all cases. So thick walled cyst even in theabsence of fatty or calcific densities is highly suggestive of anterior mediastinal teratoma.

Emphysematous cholecystitis is an uncommon condition which may mimic acute cholecystitis. But it differs from acute cholecystitis in its relatively greater frequency in men and diabetics and has graver prognosis. The condition is diagnosed by demonstration of air in lumen,wall of gallbladder and/or pericholecystic space using a variety of radiographic techniques: simple abdominal radiography, ultrasonography and CT scanning. One illustrative case is presented herein and the pertinent literature is reviewed.

PURPOSE: Emphysematous pyelonephritis is a rare, life threatening infection of kidney and the pennephric space, characterized by the production of gas within the renal parenchyma. The aim of this study is to analyze the clinical and radiologic characteristics of emphysematous pyelonephritis. MATERIALS AND METHODS: We reviewed 7 cases of the emphysematous pyelonephritis. Six patients had plain abdominal radiographs, ultrasonograms and abdominal CT scans. Only one patient had plain radiograph and ultrasonogram. In 5 operated cases, CT findings were compared with surgical records. RESULTS: Plain radiographs showed characteristic diffuse mottling of gas in renal fossa. On sonogram, intrarenal gas was identified as echogenic loci with dirty shadows. CT scan showed inflammatory mass with gas and fluid levels in adjacent to the kidney. CT findings corresponded relatively wall with the surgical findings in regard to disease extent. CONCLUSION: lntrarenal gas in appropriate clinical setting is highly specific for emphysematous pyelonephritis. CT is the most sensitive method for demonstrating the disease extent as well as specific diagnosis.
