Among previously proposed etiological factors of chondromalacia patellae, abnormality in the extensor mechanism of the knee joint has been attributed as a cause of chondromalacia patellae by many authors Malalignment in the extensor mechanism of the knee joint is supposed to cause the positional change of patella. This positional change of patella can be measured by Q angle and P/PT ratio. Hereby we intened to classify the relationahip between the above measurement lenoting the positional change of patella and chondromalacia patellae. These values were obtained from 60 patients found to have chondromalacia patellae in Han Gang Sacred Heart Hospital, from Jan. 1977 to Sep. 1978. Values were also obtained from 60 normal persons as a control group. Thus a statistical analysis was made for the possible relationship between extensor mechanism of the knee joint and chondromalacia patellae. The following conclusion were made, 1. The sex ratio was 1:1.3 with female preponderance. There was 26 male and 34 female patients, common age group of chondromalacia patellae was age 20-40 years. 2. The average value of Q angle was 11 in control group, while 18 in chondromalacia patellae, having the difference of 7. 3. The average values of Q angle among different sexes were reviewed. The male control group had 9 of average value of Q angle, while male chondromalacia patellae had 16. The female control group had 12 of average value of Q angle, while female chondromalacia patellae had 20. 4. The average value of P/PT ratio was 1.03 in control group, while 0.9 in chondromalacia patellae, having the difference 0.13. For P/PT ratio in different sexes, the average value was 1.01 in male control group. while 0.9 in male chondromalacia patellae. The average value of P/PT ratio was 1.04 in female control group, while 0.89 in female chondromalacia patellae, 5. For statistical survey for these differences, P value was examined by t-test methods. The statistical diffrences of Q angle in male control group and chondromalacia patellae was 3.4 and it was 2.06 in he female. The difference between control group and the chondromalacia patellae in the overall seves was 2.61, thus having statistical significance.

Journal of the Korean Radiological Society 1985;21(5):742-750
Intra-Arterial Digital Subtraction Angiography(IADSA) was performed in 128 patients during 13-month period. Weexperienced the same advantages of IADSA over conventional film-screen angiography:(1) significant reduction incontrast material dose: 1/3 of the dose of conventional angiography, (2) reduced film cost: 18% of the cost ofconventional technique, (3) decreased need for selective catherization,(4) shortened examination time, and (5)more ready detection of cnntrast material.

STATEMENT OF PROBLEM: The residual monomer of denture base materials causes hypersensitivity on oral mucosa and intereferes with the mechanical properties of the cured resin. The amount of residual monomer is influenced by materials, curing cycle, processing method, and etc. PURPOSE: The aim of this study was to investigate the residual methyl methacrylate(MMA) content of injection molded denture base polymer, and to compare this with the self-cured resin and the conventional compression molded heat-cured resin. MATERIALS AND METHODS: Disc shaped test specimens (50mm in diameter and 3mm thick) were prepared in a conventional flasking technique with gypsum molding. One autopolymerized denture base resins (Vertex SC. Dentimex. Netherlands) and two heat-cured denture base resins (Vertex RS. Dentimex. Netherlands, Ivocap. Ivoclar Vivadent, USA) were used. The three types of specimens were processed according to the manufacturer's instruction. After polymerization, all specimens were stored in the dark at room emperature for 7 days. There were 10 specimens in each of the test groups. 3-mm twist drills were used to obtain the resin samples and 650mg of the drilled sample were collected for each estimation. Gas chromatography (Agillent 6890 Plus Gas Chromatograph, Agillent Co, USA) was used to determine the residual MMA content of 10 test specimens of each three types of polymer. RESULTS: The residual monomer content of injection molded denture base resins was 1.057+/- 0.141%. The residual monomer content of injection molded denture base resins was higher than that of compression molded heat cured resin (0.867+/-0.169%). However, there was no statistical significant difference between two groups (p > 0.01). The level of residual monomer in self cured resin(3.675+/-0.791) was higher than those of injection molded and compression molded heat cured resins (p<0.01). CONCLUSION: With respect to ISO specification pass/fail test (2.2% mass fraction) of residual monomer, injection molding technique(1.057+/-0.141%) is a clinicaly useful and safe technique in terms of residual monomer.

Plaster of Paris is an effective ancillary treatment in the surgery of infected cavities in bone. It is well tolerated and spontaneously absorbed over the period of weeks to months, being replaced by bone of normal architecture. When the antibiotics incorporated into plaster of Paris, the antibiotics are capable of prolonged local release in bactericidal concentrations. Therefore it is proposed that antibiotics loaded plaster of Paris might be a simple adjuvant technique after good surgical debridement for the treatment of bone infection. The authors carried out an experiment to study the effect of plaster of Paris containing antibiotics for a prevention of experimental osteomyelitis, using 45 rats, which were divided into 3 groups. In the Group 1, a defect was made at the proximal metaphysis of the tibia, inoculated by Staphylococcus aureus sensitive to Cephradine and Tobramycin and then filled with plaster of Paris pellet. In the Group 2, a defect was filled with Cephradine loaded plaster of Paris pellet. In the Group 3, a defect was filled with Tobramycin loaded plaster of Paris pellet. Then we observed the healing process of the bone defect in the point of view of the gross findings, radiologic findings and histologic findings at 4th, 8th and 12th week after operation. The results of this study were as follows:l. In the control Group;all 30 cases were infected. 2. In the Group 2;only 4 of 30 cases were infected. 3. In the Group 3;all 30 cases were not infected. 4. The plaster of Paris filled into the defect was absorbed continuously and stimulated the new bone formation.

Hepatic masses show different enhancing patterns in N bolus computed tomography: Hepatocellular carcinoma shows high-attenuation in the early enhancing phase and low-attenuation in the late enhancing phase, hemangioma shows peripheral dot-like high-attenuation in the early enhancing phase and central high-attenuation in the late enhancing phase, and metastatic cancer and cholangiocelluar carcinoma show peripheral high-attenuation rim in the early enhancing phase and central portion gradulally high attenuation in the late enhancing phase. but sometimes enhancing patterns of the hepatic masses are confuse. To evaluate the significance of the AFP level and HBsAg in differentiation of the hepatic masses, we retrospectively analyzed AFP level and HBsAg' in 228 pathologically or radiologically confirmed hepatocellular carcinomas, and 137 pathologically nonhepatocellular cacinomas. The results were as follows In hepatocellular carcinoma, AFP level above 20ng/ml was 77.8% and HBsAg positve was 72.6%. In nonhepatocellular carcinoma, AFP level above 20ng/ml was 3.7% and HBsAg positve was 16.1%. We concluded that AFP level and HBsAg are helpful to distinguish hepatocellular carcinoma from nonhepatocellular carcinoma, when IV bolus computed tomogram finding is uncertain.

Korean Journal of Urology 1968;9(2):89-91
Prolapse of bladder through vesico-vaginal fistula is quite a rare urological problem. A 38-year-old woman was admitted to the Woo Sok University Hospital with a baby head sized round mass attached to the vagina. Patient had a prolapse of uterus after having her second child birth about 10 years ago and cauterization with corrosives for the treatment of prolapse of uterus was undergone for two times. About one year prior to the admission, the prolapse of uterus recurred and cauterization with corrosives was tried again, resulting vesico-vaginal fistula through which the bladder was everted and prolapsed. Under the general anesthesia, the everted and prolapsed bladder was reduced manually in normal position and vesico-vaginal fistulectomy was performed with good result.
