Cerebral aspergillosis is a rare condition that affects primarily the immunocompromised host. Most of cerebral aspergillosis is developed by hematogenous dissemination from extracranial foci, but aspergillosis of sino-nasal origin rarely affects the CNS. In case 1, wel symptom of tumor recurrence was unilateral numbness of the chin. A 65-year-old male was admitted because of paresthesia around the left chin and left lower lip. Neurologic examination revealed hypesthesia on the left side of chin, lower lip and buccal mucous mem-brane. Bone scan (Tc-99m MDP) showed focal hot uptakes on the left mandible and left first rib. Brain CT with bone window setting showed a focal osteolytic lesion in the bone marrow of the left mandibular canal without destruction of bone cortex. Both coronal T1 weighted image and axial T2 weighted image showed focal low signal intensities on the left ramus. The pathophysiologic mechanism could be understood by identification of the pathologic focus.

PURPOSE: Kissing contusion between the posterolateral tibial plateau and lateral femoral condyle is frequently found in association with a tear of the anterior cruciate liagment (ACL). The purpose of this study was to determine which ligamentous and meniscal tears are associated with kissing contusion. MATERIALS AND METHODS: We retrospectively reviewed the findings depicted by 323 consecutive MR images of the knee and confirmed at arthroscopy. For the diagnosis of disruption, ligaments, medial menisci (MM) and lateral menisci (LM) were evaluated using accepted criteria. We compared the prevalence and location of meniscal and ligamentous tears between group I (44 knees with kissing contusion) and group II (279 knees without kissing contusion). For statistical analysis the chi-square test was used. RESULTS: ACLs were torn in all 44 knees (100%) with kissing contusion, and 78 (28%) of 279 without kissing contusion. There were ten medial collateral ligament (MCL) tears (23%) in group I, and 17 MCL tears (6%), five lateral collateral ligament (LCL) tears (2%) and ten posterior cruciate ligament (PCL) tears (4%) in group II. In group I, meniscal tears were found in 22 MM (50%) and in 19 LM (43%), while in group II, they occurred in 128 MM (46%) and 128 LM (46%). In group I, 17 (77%) of 22 MM tears and 13 (68%) of 19 LM tears were located in the posterior horn, while in group II, the corresponding figures were 97/128 (76%) and 60 of 128 (47%). The differing prevalence of ACL and MCL tears between the groups was statistically significant (p<0.05), but differences in the prevalence and location of meniscal tears were not (p>0.05). CONCLUSION: Although kissing contusion was a highly specific sign of ACL tears, its presence was also significant among MCL tears. There was no signifficant difference in meniscal tears with or without kissing contusion.

6.Topical Therapy of Thio-TEPA on Superficial Bladder Tumors.
Korean Journal of Urology 1983;24(6):1000-1004
Intravesical thio-tepa instillations for 25 patients with superficial bladder tumors were evaluated postoperatively to reconfirm its usefulness as a prophylactic agent. The over-all recurrence rate to prophylactic thio-tepa was 28%, with minor toxicity observed in 32% of the Cases. Thio-tepa Can be given safely in the postoperative period and is effective in decreasing the recurrence rate and prolonging interval free of disease of superficial bladder tumors.

8.Coagulation and Fibrinolysis in Exudative Peural Effusions.

BACKGROUND: The intrapleural hypofibrinolysis is caused by mainly excessive concentration of pleural plasminogen ogen activator inhibitor-1 antigen(PAI-1 Ag), which binds tissue type plasminogen activator. In pleural inflammation induced by sclerosing agents for pleurodesis, levels of pleural PAI-1 antigen increase in relation to decreing D-dimer levels. It has been known that the pleural mexothelial cells have the capability of secreting PAI-1 Ag in response to inflammation in vivo. Therefore, we estimated whether pleural inflammation changes the balance between fibrinolytic and coagulative properties in exudative pleural effusions. METHOD: The thirty cases was included in our study. We determined the pleural levels of glucose, lactic dehy-drogenase(LDH), pH and the counts of white blood cell(WBC), polymorpho leukocyte(PMN), lymphocyte as the parameters of pleural inflammation and cellular components of pleural fluid. The plasma level of fibrinogen in fluid and the neutrophil count in blood were determined. The levels of D-dimer, PAI-1 Ag and thrombin-antithrombin lll complex(TAT) were determined by ELISA(Behring, Marburg, Germany). RESULTS: The causes of pleural effusion were as following : tuberculous in 14 cases, malignant in 10 cases and parapneumonic in 6 cases. The levels of pleural D-dimer, PAI-1 Ag and TAT was significantly higher than that of plasma(p<0.001). The severity of pleural inflammation did not correlated with pleural D-dimer, PAI-1 Ag, TAT and their plaxma levels. But the level of pleural TAT correlated with pleural WBC and lymphocyte count. CONCLUSION: We found the the severity of pleural inflammations did not correlated with pleural D-dimer, PAI-1 Ag, TAT and the possibility of local production of PAI-1 antigen is present.

9.Histologic and Functional Alteration in the Prostate and in the Seminal Vesicle of Rat with Streptozotocin-induced Diabetes.
Korean Journal of Urology 1997;38(7):683-687
Our investigation was performed to define the effects of diabetes on the prostate and the seminal vesicle in the male rat. The histologic and functional alterations of the prostate and the seminal vesicle were examined in the control and the streptozotocin-induced diabetic rats. The most striking findings were the variable reduction in size and the gross atrophy of the prostates and the seminal vesicles from diabetic rats. Diabetic rats experienced a significant loss in total body weight relative to controls. The weight of the prostates and the seminal vesicles was markedly reduced in diabetic rats relative to controls and the rate of weight reduction of the prostate and the seminal vesicle was more severe than that of total body weight reduction. Prostate specific antigen was significantly reduced but seminal fructose was elevated in the diabetic rat. In the prostate and the seminal vesicle of the diabetic rat, there are both histologic and functional abnormalities which may be responsible for reproductive dysfunction.
