OBJECTIVE: Many evidences suggest that patients with bipolar disorder have functional abnormalities in their postreceptor signal transduction pathways, and mood stabilizing effect of lithium is exerted by modulating this dysfunctioning system. Carbamazepine, an antiepileptic agent, is also known to be effective in the treatment and prevention of bipolar disorder. But the precise mechanism of action of the drug is still poorly understood. This study was performed to elucidate the possible therapeutic mechanism of carbamazepine. METHOD: The effects of chronic carbamazepine administration on protein kinase A and protein kinase C activities in frontal cortex of rat brain after 2 weeks of drug administration were measured and compared with those of control subjects. RESULTS: Mean(+/-SE) value of activity(phosphate transfer micromol/mg of protein, min) or protein kinase A in control and test group was 0.249563+/-0.036 and 0.539853+/-0.078, and that of protein kinase C was 0.654817+/-0.053 and 1.146205+/-0.052 respectively, being increased in test group. And differences between the two groups were statistically significant for both enzymes(protein kinase A ; p<0.01, protein kinase C ;p<0.001). CONCLUSION: These results show that chronic carbamazepine administration increases protein kinase A and C activities, and concerning the possible mode of therapeutic action in bipolar disorder it is suggested that enhanced enzymes phosphorylate receptor-G-protein-effector complexes to dampen hyperfunctioning neuronal activity and thus stabilize the system.

PURPOSE: We performed the study prospectively to evaluate the advantage of fat suppression MR in the diagnosis of rotator cuff injury. MATERIALS AND METHODS: Ten symptomatic patients were studied with both conventional T2WI and FST2WI using chemical shift technique. Each image was analyzed for the assessnent of injuries, conspicuity of the lesion, the presence of effusion in subacromial bursae and joint space, and presence of humeral head injury. Arthroscopy was done in 4 patients following MRI. RESULTS: We could made presumptive diagnoses on FSMR as identical as on conventional MR in six cases(1 normal, 2 tendinitis, 2 partial thickness tear, 1 full thickness tear), two of them were confirmed by arthroscopic procedures. Two cases of partial thickness tear proved by arthroscopy were detected on FST2WI, whereas they were considered tendinitis on conventional T2Wl. There were another 2 cases who showed tendinitis on FSMR, but normal on conventional T2Wl. They, however, were not confirmed by either arthroscopy or surgical procedure. CONCLUSION: We found the FSMR were superior to conventional T2Wl in the conspicuity of lesions and detection of joint effusion and abnormalities on the humeral head. We think FSMR of the shoulder could have significant diagnostic advantages over the conventional spin-echo MR imaging.

PURPOSE: It is important for the physician and a rape counselor to understand epidemiology studies of the incidence, prevalence, spread, prevention, and control of sexual assault in a local community or a specific group of individuals. We did this study in order to find an effective treatment for the sexual assault victims and to establish a data base on them. METHODS: We prospectively evaluated sexually assaulted patients who visited the Medical Supportive Center for Women at the National Police Hospital from Oct. 11, 2001, to Oct. 10, 2002. The data were obtained from the records of the ER (emergency room) and OB & GY (obstetric & gynecologic) clinic; a total of 169 patients were evaluated. RESULTS: The mean age was 20.1 years old. The age distribution of sexual assault victims was divided into four: 14 cases under 7 years of age (8.3%), 26 cases between ages 7 and 13 years (15%), 43 cases between ages 14 and 19 years (26.3%), and 86 cases over 20 years of age (52.6%). Of the patients, 157 (92.9%) were unmarried and 117 (69.2%) were examined within 1 hour after visiting the hospital. The physical injuries were 15 vaginal injuries (26.9%), 34 ruptures of the hymen (16.9%), 1 sexually transmitted disease (0.6%), 57 abnormal sensations of the genital organ (28.3%), and 55 minor injuries including abrasions, contusions, and lacerations (27.3%). The psychological injuries were 105 phobias (21.4%), 92 anxieties (18.8%), 68 angers (13.9), 51 guilts (10.4%), and the like. Eighty-eight patients (52.1%) were acquainted with the assailant. CONCLUSION: Optimal management of sexual assault victims should involve continuous epidemiologic analysis and the estalishment of an assault-victim data base.

Indirect composite resin are used as an popular effective esthetic material in prosthetic dentistry, often with metallic substructure that provides support for restorations. Recently, new indirect composite resins as a substitute of ceramic have been developed. These resins provide good esthetics, with a wide range of hue and chroma. And the flexural strength of those is in the range of 120-150MPa, which is higher than that of feldspathic ceramic, and similar tot hat of Dicor. Although it has many merits, one of the major clinical problems of composite resins is the bond failure between metal and resin due to insufficient interfacial bond strength. The purpose of this study was to evaluate shear bond strength of the reinforced indirect composite resin to dental alloys. Three different composite resin systems(Artglass . Sculpture , Targis ) as test groups and ceramic(VMK 68 ) as control group were bonded to Ni-Cr-Be alloy(Rexillium III ) and gold alloy(Dave 4). All specimens were stored at 37degrees C distilled water for 24 hours and the half of specimens were thermocycled 2000 times at temperature from 5degrees C to 60degrees C. The shear bond strengths of reinforced indirect composite resins to dental alloys were measured by using the universal testing machine, and modes of debonding were observed by stereoscope and scanning electron microscope. The results were as follows : 1. The shear bond strengths of reinforced indirect composit resins to dental alloys were approximately half those of ceramic to dental alloys(P<0.01). 2. There was no significant difference between the shear bond strength of several reinforced indirect composite resins to metal. 3. Alloy type did not affect on the shear bond strengths of resin to metal, but the shear bond strengths of ceramic to gold alloys were higher than those of ceramic to Ni-Cr alloys(P<0.05). 4. The shear bond strenghts of Artglass and Targis to gold alloys were significantly decreased after thermocycling treatment(P<0.01). 5. Sculpture showed cohesive, adhesive, and mixed failure modes, but Artglass and Targis showed adhesive or mixed failures. And ceramic showed cohesive and mixed failures.

Core decompression is still widely used in avascular necrosis of the femoral head but the results are unpredictable and the indications are not settled yet. The reparative process of the decompressed femoral head is poorly understood. Seven cases in 5 patients were undertaken THRA following failed decompression and these were studied for the radiological and pathological changes of the core tracts. The lesions of failed cases were involved more than 1/3 of femoral head on MRI and all cases were stage II A or B. The extent of the necrotic area in MRI was enlarged with crack, sclerosis and sometimes gas collection. Depression of the subchondral plates were also observed. Capillary ingrowth or neovascularization was not found at all and there were only fibrosis, inflammatory response and foreign body reactions.
