The meniscus has improtant functions of shock absorption, load transmission, lubrication and significant contribution to stability of the knee. Accordingly, repair rather than excision can be expectd to be satisfactory and functional teatment for knee joint. We had Repaired 56 cases of meniscal tears from March, 1987 to September of 1992, among which 42 cases were followed up for at least 12 months to 60 months at most(in average 36 months). The results were as follows; 1) In medial meniscal tears, 26 cases were acute, while five were chronic. As for the lateral meniscus, acute and chronic teats were observed in nine and two cases, respectively. 2) Eleven of the 35 acute tears were associated with anterior cruciate ligament tears, while three of seven chronic tears were associated with anterior cruciate ligament tears. 3) Second-look arthroscopic examinations were performed on nine repaired cases. Retears occurred in two cases and seven cases revealed healing at repair sites. 4) Two cases(5%) out of 42 repaired menisci were return during follow-up. One was a case of isolated meniscal tear and the other was associated with rupture of anterior cruciate ligament. 5) Two return cases were repaired in the chronic stage of more than one year after trauma. 6) The standing radiographs which were taken in full extension and 45 flexion on eight out of 13 patients, who had been followed up for more than 4 years showed intact joint space without narrowing.

PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signifiant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers(CCi=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.

The purpose of this study was to evaluate the influence of high dose carbon tetrachloride (CCI4) on the hepatotoxic effect of dimethylnitrosamine (DMN) which induces acute hemorrhagic necrosis in liver. Rats were injected intraperitoneally DMN dissolved in physiologic saline by a dose of 40 mg/kg. For changes related to CCI⁴ pretreatment, rats were injected intraperitoneally CCI⁴ dissolved in olive oil by a dose of 0.4 mg/kg, and then injected DMN. The livers were extracted from the rats 3, 6, 12, 24, 48, 72, and 120 hours after CCI⁴ and/ or DMN injection. Liver tissues were examined with light and electron microscopes. The results were summarized as follows; Light microscopic findings: Severe centrilobular hemorrhagic necrosis developed from 12 hours after injection of DMN and continued to 120 hours. On injection of DMN after CCI4 pretreatment, Massive necrosis occurred early. But active regenerative changes were produced in 24 hours. In 120 hours, the liver recovered in almost normal appearance. The degree of necrosis in pretreated group was similar to that in DMN injection only, and the time of recovery was faster in pretreated group. Electron microscopic findings: The early change was mainly disorganization of RER in DMN injection, and clumping and vesicular dilatation of ER in injection of CCI4. In pretreatment group, the early change was similar in appearance with CCI4 group, but severer in degree. According to the results, it was revealed that acute toxic effect of DMN was recovered more rapidly in pretreatment group. Thus it was suggested that CCI4 had protective effect in DMN hepatotoxicity.

A 2-month-old Korean boy presented with a solitary papule on the cheek which was noted at birth. Histopathologic findings were consistent with angiofibroma of fibrous papule of the face (FPF). FPF is known to affect adults, and congenital occurrence has not been reported to the best of our knowledge. We report a case of congenital FPF which showed a facial papule clinically and an angiofibroma histologically.

In order to assess the effects of diazepam and meperidine as premedication for upper gastrointestinal endoscopy, eighty eight patients undergone an elective upper gastrointestinal endoscopy were studied. Studied patients were divided into two groups; one group was premedicated with buscopan and stropine(group I), and the other group was premedicated with diazepam and meperidien (group II). The results obtained were summarized as follows; 1) 83.0% of the group II (44/53) did not eomplain any discomfort by the procedure, but only 23.9% (8/35) of the group I showed no discopmort. The difference between two groups is statiatieally significant (p<0.005). 2) In 41 patients with previous experience of endoscopy, 22 patients from 27 of the graup Il(81.5%) did not feel any discomfort but it wes only 3 patients among 14 of the group I (21.4%) who did not feel discomfart (p<0,005). 3) In 47 patients without previous experience of endoscopy, 23 patients from 26 of the group II (88. 5%) did not show discomfort but it way only 5 patients among 21 of the group I (23.7%) (p<0.005). 4) In the patients with previous experience of endoscopy, 21 patients among 27 of the group II (77. 8%) felt better than that of the previous experience but it was only 3 patients among 14 of the group I (21.4%) (p<0.005). From the above results, we would emphasize that it is more effective to use diazepam and, meperidien as premendication for the gastrointestinal endoscopic procedure since it removes pstients apprehension rendering them a good cooperation with very minimal side effects,

We reviewed 178 patients with hypertensive intracerebral hematoma(HICH), which were treated with computed tomography(CT) guided stereotactic aspiration from Aug. 1986 to Dec. 1993(166 CT guided U-loop and 12 Leksell system). Our series consisted of 82 males and 96 females. The hemorrhages were located in putamen in 67.4%, thalamus in 20.2%, subcortex in 9% and cerebellum in 3.4%. Mean removal rate of hematoma was 55.3%. The results for the 178 cases who underwent stereotactic aspiration were good recovery in 45.5%, moderate disability in 28.0%, severe disability in 9.0% and vegetative state in 4.0%. The infection rate and rebleeding rate of all cases were 1.7% and 6.8% respectively. The mortality rate of all cases was 13.5%. We analysed the factors affecting the prognosis in 178 patients. Factors affecting good prognosis were high initial GCS, less amount of initial hematoma and no presence of intraventricular hemorrhage. Stereotactic aspiration by CT-guided U-loop and Leksell system is simple, safe and can minimize the brain damage. This method can e performed under local anesthesia.
