This study was undertaken to investigate immunological mechanisms in Behçet's syndrome, a function considered important in the pathogenesis of the disease. The activity of interleukin-2 (IL-2), which is believed, to play a central role in the regulation of both cell-mediated and humoral T cell-dependent immune responses, measured in 46 patients with complete, in-complete or suspected Behçet's syndrome. The results were as follows: 1 . There was no significant difference between the average IL-2 activity of patients and control group. 2. For each clinical subtype of Behçet's syndrome, IL-2 activity was lower than the control value, but the difference was not statistically significant. 3. In mucocutaneous and ocular types, the greater the clinical symptoms, the lower the value of IL-2 activity. However, the decrease of IL-2 activity was not statistically significant. In conclusion, IL-2 activity of phytohemaggludnin (PHIS-stimulated peripheral blood lymphocytes in patients with Behçet's syndrome was not significantly decreased compared to control population.

A clinico-pathological study on the true skin appendage tumors was carried on the accumulated cases during pat 11 years from 1976 to 1986 years in the Department of Pathology, Seoul National University Hospital. The results was as follows; 1) Among various benign skin appendage tumors pilomatricoma was the most common benign tumor consisting of 72 out of 244 cases (30.1%), followed by dermoid cyst 48 cases (20.0%), steatocystoma multiplex 37 cases (15.5%), syringoma 33 cases (13.8%) and trichilemmal cyst 19 cases (0.8%). Other benign skin appendage tumors were rarely noted under 3%. Sebaceous carcinoma was most common among malignant skin appendage tumors and no malignant tumor of sweat gland origin was noted. 2) The sex ratio of male to female of the pilomatricoma was 1 : 2.6 and on the face, neck, and extremeties in 1st and 2nd decades. The sex ratio of dermoid cyst was 1 : 1.2 on the face in 1st decade. The sex ratio of steatocystoma multiplex was 1 : 1.9 and on the trunk in 3rd decade. The sex ratio of syringoma was 1 : 7 and on the face in 5th decade. The sex ratio of trichilemmoma was 1 : 1.6 and on the trunk in 5th decade. Other tumors were not avaiable for analysis because of small number. The sex ratio of sebaceous carcinoma was 1 : 2 and on the eyelid in 6th decade

Loss of continuity of the mandible destroys the balance and symmetry of mandibular function, leading to altered mandibular movements and deviation of the residual fragment towards the resected side. Apart from deviation, other dysfunctions include difficulty in swallowing, speech, mandibular movements, mastication, and respiration are accompanied. In general, surgical reconstruction is considered first then proceeds to the prosthetic restorations. However, patients with systemic disease such as BRONJ (Bisphosphonate related osteonecrosis of the Jaw), surgical reconstruction may be limited. Thus, the prosthetic restoration remains as the only resort. Numerous prosthetic methods are employed to minimize deviation and to improve masticatory efficiency, function and esthetics. If a removable partial denture is the selected treatment modality, maximum stability of the partial denture base may be accomplished with a functional impression procedure by means of eliminating lateral and horizontal forces caused by the functional movements of the lips, cheeks and tongue. Also, Twin occlusion is used to obtain a favorable occlusal relationship and check support for esthetics. The purpose of this case report is to demonstrate how neutral zone impression technique and twin occlusion scheme were applied to restore a hemi-mandiblectomy patient with BRONJ syndrome to achieve satisfactory results in functional and esthetic aspects.

BACKGROUND/AIMS: Hepatocytes on the hepatic lobule mipate from portal zone to centrilobular mea as the DNA synthesis within it. And also, the xenobiotic reactions reveal characteristic differences associated with zone specific metabolism in the liver acinus. In this study, the zonal distribution of ethylnitrosourea (ENU)-induced hepatic precancerous lesion was stereologically investigated. METHODS: Nine B6C3F1 mices were given I.p. injection of ENU (60 ug/pn body weight) when the pups were 15 days old prior to sacrifices at 8 weeks of life. All the 150 consecutive sections, 3 p m in thickness, were stained with hematoxylin and eosin and identified the basophilic precancerous lesions with 80-165 p m diameter in equatorial plane by the Zeiss microprojector. And then the distances from the center of selected foci to terminal hepatic vein or portal vein branches were estimated under the microscopic fields. As a control group, the same estimations were performed from the random points by the appointments of random digit table. RESULTS: Mean distance between ENU-induced 52 hepatocellular foci and the nearest terminal hepytic vein was 181.15+112.39 p m (Mean+ SD), but that of randomly selected 104 points was 291.73+157.98pm (Mean+5D) (Students t-test, p<0.0005). Substantially, 52.7% of ENU-induced 52 hepatocellular foci were within 300 p m from the terminal hepatic vein, but randomly selected 104 points were only 50.9% (Shapiro Wilk W test, w=0.819857, p=0.048038). Mean distance from ENU-induced 52 foci to portal vein was 398.85+149.98pm (Mean+SD), but that from the randomly selected 104 points was 315.87+145.79 pm (Mean+SD)(Students t-test, p<0.0005). CONCLUSION: Stereologically, ENU-induced mice liver cell foci distribute non-randomly to Zone III, centrilobular zone of mouse hepatic acini where promote invasion toward terminal hepatic veins.

OBJECTIVE: The purpose of this retrospective study was to report the outcome of the endovascular treatment of eight patients with eight saccular posterior inferior cerebellar artery (PICA) aneurysms. MATERIALS AND METHODS: Over the last seven years (1999-2006), eight consecutive patients with saccular PICA aneurysms were treated by endovascular methods. Five of the aneurysms were presented with subarachnoid hemorrhaging, whereas three were discovered incidentally. Four of the aneurysms (3 ruptured and 1 incidental) were treated by intrasaccular coiling, whereas the remaining four (1 ruptured and 3 incidental) were treated by vertebral artery (VA) occlusion. RESULTS: Of the four aneurysms treated by intrasaccular coiling, three were completely packed with coils and one was partially packed. In three of four patients who underwent vertebral artery occlusions, follow-up digital subtraction angiographies demonstrated thrombosed aneurysms and PICA. No procedure-related morbidity occurred and no re-bleed was encountered during a follow-up examination (mean; 31 months). CONCLUSION: As a result of this study, we found that the endovascular management of saccular PICA aneurysms should be considered as safe and effective.

Prolonged administration of anterior hypophyseal, adrenocortical, or thyroid hormones is known to cause degeneration, degranulation and necrosis of the beta-cells in the Langerhans islets of the pancreas. However, the effects of extirpation of these endocrine glands upon the Langerhans islets has not been reported, a1though it is known that removal of any of these glands bring about hypoglycemia, decreased tissue uptake of glucose, and increased tissue sensitivity to insulin. The present investigation is studies of the morphologic alterations of the beta-cells in the Langerhans islets following hypophysectomy, adrenalectomy, or thyroidectomy in rats. Hypophysectomy, adrenalectomy, and thyroidectomy, all induce similar morphologic alterations in the beta-cells of the islets. These consist of increased beta-cell population, the accumlnation of beta-granules, and atrophy of the individual betacell. Therefore, these changes are considered to be not specific following the withdrawal of specific hormones but a common effect of the hypoglycemia due to removal of the hypophysis, adrenals, or thyroid glands. A similar common degeneration of the beta-cells due to hyperglycemia occurs when hormones of these endocrine glands are given excessively.

Beta adrenergic receptors(beta-ARs) were detected in retina, trabecular meshwork, iris and ciliary body in eye of human, cat, rabbit, and bovine using in vitro autoradiography and majority of the beta-ARs found in eye are the beta2 subtype. Recently, the beta2-AR gene has been cloned from hamster, human, rat and monkey using molecular biological methods. Expression of beta2-AR mRNA were demonstrated in smooth muscle, kidney, ovary, brain, adipose tissue, heart, epithelial cells, thymus, lung and liver. However, studies about expression and distribution of beta2-AR mRNA in the eye have not been done yet. Author have characterized the expression of beta2-AR mRNA in rat eye using in situ hybridization with 35S-UTP riboprobe. beta2-AR mRNA was expressed in corneal epithelium and stroma, ciliary epithelium, vessels of ciliary body, choroidal vessel, and retina. In contrast it was not expressed in iris and sclera in the rat eyes. These results support the hypothesis that beta2-AR mRNA may be synthesized in the various ocular tissue and its characterized distribution suggests partially that beta2-ARs are related with aqueous production and blood supply of the eye.

The intracranial mycotic aneurysms are a rare complication in patients with infective endocarditis, and the management of the aneurysm is controversial. We presented a case of a 50-year-old woman who had infective endocarditis, complicated by an intracranial mycotic aneurysm of distal branch of the right anterior cerebral artery. Endovascular treatment using cyanoacrylate led to a successful result.
