We have experienced an unusual case of hemorrhagic renal cyst in the rt. kidney at 58 years old woman. The Rt. kidney was enlarged, and showed a few subcapsular ischemic areas The color of kidney was dark brown. As the cyst at lower pole of rt. kidney was dissected, hemorrhagic fluid visualized in the cystic cavity. The final pathologic finding was renal cyst associated with malignant change and renal cell carcinoma at another renal parenchyma. Herein, hemorrhagic renal cyst, a rare clinical entity, was reported with review of literatures.

Uterine scar dehiscence following laparoscopic myomectomy rarely occurs but can compromise both maternal and fetal well-being in subsequent pregnancy. We here present two cases of pregnancy complicated by preterm birth that resulted from uterine scar dehiscence following laparoscopic myomectomy. First case was a nulligravida who had scar dehiscence at 26 weeks of gestation after having a laparoscopic myomectomy 3 months prior to conception. Two weeks later, we observed her fetal leg protruding through the defect. The other case was a primigravida with a history of prior cesarean delivery, whose sonography revealed myomectomy scar dehiscence at 31 weeks of gestation. Within a few hours after observing, the patient complained of abdominal pain that was aggravating as fetal leg protruded through the defect. In both cases, babies were born by emergency cesarean section. Conservative management can be one of treatment options for myomectomy scar dehiscence in preterm pregnancy. However, clinicians should always be aware of the possibility of obstetric emergencies.

The tape-worm spirometra mansonoides infests man world-widely, particularly in Asian countries with rare involvement of the central nervous system. Recently, the authors have experienced 7 cases of cerebral sparganosis, and reviewed their clinical manifestation, radiographic findings, operative and pathologic findings, and follow-up results. The cerebral sparganosis manifests headache, seizure, or hemiparesis. Most of patient had episodes of eating frogs or snakes. The brain CT scan showed low density area with ipsilateral ventricular dilatation. Enzyme linked immunosorbent assay(ELISA) test showed positive response to serum and cerebrospinal fluid. The best treatment for cerebral sparganosis mansoni is surgical removal, from which we confirmed 4(17%) cases of live worms in operative and patholgic findings, and most of the seizure disappeared or decreased after operation.

Five separate incidences of patients with cerebrovascular disease(CVD) were revealed among 555 craniocerebral traumatic victims between 1991 and 192. The 5 cases of with cerebrovascular disease revealed included 3 aneurysm. 1 arteriovenous malformation and 1 spontaneous intracerebral hematoma caused by angiographic study. The frequent use of computerized tomographic scans in the evaluation of head-injured victims can well demonstrate an intracerebral hemorrhage, but may not ge able to detect the associated cerebrovascular disease;whereas the efficacy of angiogrphy, on the contrary, has been losing its popularity as diagnostic armamentarium. The importance of angiographic study should be considered, if clinical signs and/or brain CT ideate the possibility of cerebrovascular disease even during the course of head injury management.

It has been reported that receptor-bound blocking type TSH receptor antibody (TRAb) can be converted to the stimulating type by anti-human IgG antibodies. To evaluate the relationship between the conversion of receptor-bound blocking type TRAb to the stimulating type and the biological activity of blocking type TRAb, we compared converting activities of blocking type TRAb from 10 patients with primary nongoitrous hypothyroidism with both the doses of blocking type TRAb which show 50% inhibition of 125I-bTSH binding to the TSH receptor and those which show 50% inhibition of TSH-stimulated cAMP production in cultured rat thyroid cells (FRTL-5). The additions of anti-human IgG antibody to FRTL-5 cell-bound blocking IgGs resulted in the increase in cAMP production in a dose-dependent manner and the converting activities (percent increase of cAMP production) also depended on the doses of blocking IgGs. The converting activities were significantly correlated with the doses of blocking IgGs which showed 50% inhibition of 125I-bTSH binding to the TSH receptor (r = 0.71, p = 0.011). And these converting activities were also significantly correlated with the doses of blocking IgGs which showed 50% inhibition of TSH-stimulated cAMP increase (r = 0.81, p = 0.002), and were negatively correlated with thyroid stimulation blocking antibody activities (r = 0.58, p = 0.02). We have demonstrated that all cell-bound blocking type TRAb were converted to the stimulating type by anti-human IgG antibody and the degree of conversion was negatively correlated with the biological activity of blocking type TRAb.(ABSTRACT TRUNCATED AT 250 WORDS)

To investigate the correlation between optic nerve head configuration and visual field defects, optie nerve head analysis using confocal scanning laser tomography (Heidelberg Retina Tomograph, HRT) and automated static threshold perimetry using a Humphrey Field Analyzer (program C3O-2) were performed on 81 eyes of 44 primary open-angle glaucoma (POAG) patients. The optic nerve head parameters-rim area, rim volume, mean retinal nerve fiber layer thickness, height variation contour, and third moment in contour were measured by HRT and were analyzed for correlation with visual field indices-mean deviation, and corrected pattern standard deviation. All optic nerve hend parameters except HVC correlated significantly with the visual field indices; the highest correlation was between rim area and mean deviation (r = 0.6172, p < 0.O0001). The rim area of the superior and inferior quadrants correlated significantly with the visual field defects in corresponding sectors. Structural optic disc measurements by HRT correlated significantly with funetional optic nerve head damage in POAG

Dislodgement of a crown or extension bridge and the loosening of a retainer of a bridge is a serious clinical problem in fixed restoration. Generally these problems are considered to be associated with deformation of the restoration. During biting, the restoration is subjected to complex forces and deforms considerably within the limit of its elasticity. Deformation of the restoration under the occlusal force induces excessive stress in the cement film, which then leads to the cement fracture. Such a fracture may eventually cause loss of the restoration. Because most of the past retention tests for full veneer crown were done without fatigue loading, they were not exactly simulating intraoral environment. And the purpose of this study was to evaluate the effect of cyclic cantilever loading on the retentive strength of full veneer crowns depending on different type of cements and taper of prepared abutment. Steel dies with 8degrees or 16degrees convergence angle were fabricated through milling and crowns with the same method. These dies and crowns were divided into 8 groups. Group 1: 16degrees taper die, cementation with zinc phosphate cement, without loading Group 2: 16'taper die, cementation with zinc phosphate cement, with loading Group 3: 8degrees taper die, cementation with zinc phosphate cement, without loading Group 4: 8degrees taper die, cementation with zinc phosphate cement, with loading Group 5: 16degrees taper die, cementation with Panavia 21, without loading Group 6: 16degrees taper die, cementation with Panavia 21, with loading Group 7: 8degrees taper die, cementation with Panavia 21, without loading Group 8: 8degrees taper die, cementation with Panavia 21, with loading After checking the fit of die and crown, the luting surface of dies and inner surface of crowns were air-abraded for 10 seconds. The crowns were cemented to the dies, with cements mixed ac cording to the manufacturer' s recommendations. A static load of 5 kg was then applied for 10 min utes with static loading device. Twenty-four hours later, group 1,3,5,7 were only thermocycled, group 2,4,6,8 were subjected to cyclic loading after thermocycling. Retentive tests were performed on the Instron machine. From, the finding of this study, the following conclusions were obtained. 1. Panavia 21 showed significantly higher retentive strength than zinc phosphate cement for all groups(p<0.05). 2. There was a significant difference in the retentive strength between 8degrees and 16degrees taper for zinc phosphate cement(p<0.05), but no significant difference for Panavia 21(p>0.05). 3. Cyclic loading significantly decreased the retentive strength for all groups (p<0.05) . 4. For zinc phosphate cement, there was 35% reduction of the retentive strength after loading in the 16degrees taper die, 25% in the 8degrees taper die, and for Panavia 21, 21% in the 16degrees taper die, 18% in the 8degrees taper die.

This study was undertaken to investigate the immunological mechanism of Behqet s syndrome, considered to be important in the pathogenesis of the disease. Seventy- three patients with complete, incomplete and suspected types of Behget's syndrotne were tested for leukocyte migration ingibition factor(LIF), one of the lymphokines. The results were as follows : 1. There was no difference between the average LIF activity of all the patients and that of eontrol. 2. LIF activity of complete type, according to Shirnizus classification, was significaritly lower than the control value. 3. LIF activity of ocular type, according to Lehners classification, was signficantly lower than the control value. 4. LIF activity for patients with 4 clinical symptoms was well below the value for patients with less symptomes 5. For patients with single clinical symptom, LIF activity of complete type was well below the values of incomplete and suspected types. 6. In suspected and mucocutaneous types, LIF activity was low when the patients showed two clinical symptoms than one. Thus, LIF activity was low for patients with complete, ocular and neurological types and with multiple symptorns.
