Rat thalamocortical slices maintain synoptic connections between thalamus and cortex. When perfused with low Mg++-ACSF, thalamocortical slices exhibited two main types of spontaneous bursting activity. One is monotonic burst of 3-15 Hz and another is multiphasic bursts which have a tonic burst firing period and a late phase of clonic burst firing. These bursts are similar in frequency and during to EEG recordings from human generalized seizures. Exploiting the advantages of in vitro preparations, the electrophysiological action of taurine were studied. Exogeneous application of taurine profoundly decreased spontaneous bursting activities, which it caused only slight reduction of electrically evoked response in cortical layer. Taurine-induced current was blocked by 40 uM bicuculline, GABA receptor antagonist, in acutely isolated coritcal neurons. These results suggest that endogeneous taurine may regulate the hyperexcitablility through GABAa receptor.

Augmentation cystoplasty is effective in the rehabilitation of the contracted bladder of small capacity caused by tuberculosis or interstitial cystitis refractory to more conservative methods of management. Genitourinary tuberculosis is the most common cause of contracted bladder in Korea and it may lead to considerable vesicoureteral reflux and progressive deterioration of renal function. The use of hemi-Kock ileal pouch with an afferent intussuscepted nipple is a suitable solution in patient in whom the bladder outflow tract provides adequate resistance and supratrigonal cystectomy is to be performed with construction of an antireflux mechanism. Herein, we report 4 cases of hemi-Kock ileocystoplasty.

Central serous chorioretinopathy was defined as an isolated serous elevation of macular retina unassociated with subretinal blood, optic nerve head pathology, or evidence of other retinochoroidal or systemic disease. A review of 259 consecutive cases of patients under the age of 40 years with central serous chorioretinopathy seen between 1976 and 1985 was performed in order to define temporal patterns of occurrence. Although an increased number of cases were seen in June and July, a statistical trend analysis failed to confirm a defini te seasonal variation(p>0.1).

PURPOSE: To evaluate the passive subluxation of the tibia on MR' images in patient with both anterior cruciate ligament (ACL) and medial collateral ligament (MCL) tears and to demonstrate the usefulness of its measurement. MATERIALS & METHODS: The authors performed a retrospective study of 123 knees with tears of both ACL (complete, n=70, partial, n=53) and MCL (complete, n=10, partial, n=113). ACL tears were documented at arthroscopy and MCL tears were interpreted by abnormal MR findings. One hundred normal knees were also studied for comparison. Using new internal landmarks, anterior subluxation was measured on an intercondylar sagittal image and lateral subluxation was measured on a mid-coronal image. RESULTS: Anterior subluxation of 3 mm or more was seen in 45/123(37%) abnormal knees, lateral subluxation of 3 mm or more in 20/123 (16%), and anterolateral subluxation in 15/123 (12%). Anterior subluxation of 5mm or more was seen in 25/70 (36%) complete ACL tears, and no knees with partial ACL tears showed anterior subluxation of 5 mm or more. CONCLUSION: Static anterolateral subluxation of the tibia occurs in knees with combined ACL and MCL tears, as measured on routine MR imaging. These measurements may help confirm the presence of ligament injuries and differentiate complete from partial ACLtear.

10.A Case of Angioid Streaks Associated with Pseudoxanthoma Elasticum.

Angioid streaks are easily recognized although relatively rare. They are typically described as irregularly radiating lines extending from the peripapillary area peripherally. They are usually bilateral, and are characteristically found in the posterior pole. Angioid streaks may occur alone or in association with various systemic diseases. Pseudoxanthoma elasticum is a relatively uncommon disorder of elastic tissue involving dermal, ocular, gastrointestinal, and cardiovascular tissues. We examined a case of angioid streaks associated with pseudoxanthoma elasticum found in a 31 year-old female and presented a brief review of the relating literatures.
