To evaluate the efficacy of STIR (short tau inversio recovery) image in the diagnosis of orbital diseases, we compared the STIR images with conventional SE(spin-echo) images in 17 patients. The fat signal was reliably nulled at inversion time of approximately 160-170 msec in all cases. We analyzed all the cases in the aspects of the detection of lesion and the lesion-to-back ground contrast retrospectively. Regarding lesion, the detection rates of STIR, T1 and T2-weighted images were 89, 88 and 83% respectively. In the aspect of lesion-to-background contrast, the contrast ratios of STIR and T1, T2-weighted image were 87% and 64, 56%, respectively. In conclusion, STIR images were similar to T1-and T2-weighted images in the detection of lesion, but superior in the aspect of lesion-to-background contrast. So the STIR images may be a useful adjunct to conventional SE images for the diagnosis of orbital disease.

It has been suggested that the fish oil can reduce atherogenesis in humans and animals, and that peroxidation of lipoproteins may be a major factor causing atherosclerotic lesions. We tested these posibilities in rabbits fed an atherogenic diet by comparing the effect of a eicosapentaenoic acid(EPA: a major component of fish oil)supplement and a butyrated hydroxyanisole(BHA: antioxidant)diet supplement. Tweenty-eight young male New Zealand White rabbits were used in this study. The animals were divided by control, cholesterol fed only, cholesterol + EPA, and cholesterol + BHA groups. The experimental course lasted 12 weeks and animals were sacrificed periodically(2, 5, 8, 12weeks)for quantitative studies of aortic atherosclerosis using light and electron microscopy. Plasma cholesterol levels were determined and lipopreteins were separated periodically. The cholesterol fed only group showed an increased serum cholseterol level and atherosclerotic lesions from 5 weeks of experiments. The EPA supplement resulted in similiar serum cholesterol levels with cholesterol fed only group, but greater lesion than cholesterol fed only group. The BHA supplement resulted in higher serum cholesterol levels except VLDL-cholesterol than EPA supplement group. However, the atherosclerotic lesion was not increased. Our studies support the theory that oxidative modification of lipoproteins is important for the atherogenesis and antioxidant may have a protective effect. However, it failed to show antiatherogenesis effect of fish oil.

Metabolic acidosis (MA) is associated with increased proteolysis, increased osteoclast activity and blunted cardiac muscle response, but the effect of MA on various clinic al parameters in CAPD patients is not well known. To evaluate the effects of MA on serum albumin level and other nutritional parameters in CAPD patients, we studied 106 CAPD patients retrospectively who have had monthly biochemical measurement and urea kinetic studies every 6 months for more than 2 years. The patients were divided into three groups according to their mean total CO2 (tCO2) level of the 2-year follow-up (Group l; mean tCO2 < 22mM/L, Group ll; 22mM/L < or = mean tCO2 < 26mM/L, and Group lll; mean tCO2 > or = 26mM/L), and the clinical, biochemical, and urea kinetic data were compared among the three groups. 1)The mean age of the subjects was 46.9+/-12.2 years with a sex ratio of 1.2:1, the mean CAPD duration 28.3+/-21.8 months, mean body weight (Bwt) 59.0+/-8.9kg, %Bwt/IBW 104.1+/-11.5%, %LBM/Bwt 75.5+/-11.1% and well-nourished patients by subjective global assessment (SGA) were 65%. 2)The mean BUN, creatinine, total protein and albumin of all patients were 55.6+/-13.6mg/dL, 12.3+/-3.5mg/dL, 6.6+/-0.7g/dL and 4.0+/-0.4g/dL, respectively. In urea kinetic study, the mean NPCR, weekly Kt/ Vurea, SCCr and RRF were 0.96+/-0.16g/kg/day, 2.02+/-0.37, 63.7+/-18.4L/week/1.73m2, and 0.99+/-1.32ml/ min, respectively. 3)The mean age was significantly higher in group l (51.0+/-10.8) than those of group ll (47.0+/-12.4) and lll (42.6+/-11.4) (P<0.05). %Bwt/IBW of group l (114.4+/-15.8%) was also significantly higher than those of group ll (104.6+/-12.6%) and lll (103.5+/-13.7 %) (P<0.05), but there were no significant differences in sex ratio, CAPD duration, %LBM/Bwt, and SGA among the three groups. 4)The mean tCO2 in group l, group ll, and group lll were 20.6+/-1.2mM/L, 23.9+/-1.1mM/L, and 27.3+/-0.8mM/L, respectively. Compared to group lll, group l had significantly higher BUN (61.1+/-14.3 vs. 46.1+/-7.2mg/dL, P<0.05) and serum albumin (4.04+/-0.31 vs. 3.75+/-0.39g/dL, P<0.05), in spite of comparable dialysis dose and albumin loss into dialysate. 5)NPCR (1.02+/-0.21g/kg/day vs. 0.88+/-0.14g/kg/ day, P<0.05) and ultrafiltration volume (1.4+/-0.4 vs. 1.0+/-0.3, P<0.05) were significantly higher in group l than those of group lll. But there were no significant differences in Kt/Vurea, SCCr, RRF, and 24-hour dialysate loss of protein/albumin among the three groups. 6)No differences were observed among the three groups in the changes of body weight, %Bwt/IBW, %LBM/Bwt, BUN, albumin, NPCR, and RRF from the baseline values after the 2-year follow-up. 7)There were significant inverse correlations between the mean tCO2 level and NPCR (r=-0.33, P<0.001), %Bwt/IBW (r=-0.32, P<0.001), RRF (r=-0.29, P<0.005), and serum albumin level (r=-0.24, P<0.05). But, creatinine, %LBM/Bwt, and Kt/Vurea did not show any correlation with the mean tCO2 level. 8)Using stepwise multiple regression analysis, NPCR (beta=-0.3491, P<0.001), %Bwt/IBW (beta=-0.046, P<0.001), and ultrafiltration volume (beta=-0.0012, P< 0.005) were independent factors affecting the mean tCO2 level. In conclusion, low total CO2 level in long-term CAPD patients may reflect increased protein intake and mild to moderate degree of metabolic acidosis may not affect the nutritional status of well-dialyzed CAPD patients.

OBJECTIVE: Although the prevalence of pulmonary tuberculosis has decreased progressively after the national control program for tuberculosis began, nowadays the number of MDRTB is increasing seriously. MDRTB tends to be poor responsive to current antituberculosis regimens. It is mainly due to poor compliance, high rate of side reaction of secondary drugs, and limitation in number of available drugs. The purpose of present study is to evaluate the clinical features of pulmonary tuberculosis patients admitted in one national tuberculosis hospital and to expose the problems pertaining to current remedies, to increase the treatment efficacy for pulmonary tuberculosis including MDRTB in the end. METHOD: Retrospective analysis of 336 pulmonary tuberculosis patients admitted in National Masan Tuberculosis Hospital was done. Contents of analysis were patients profile, the first diagnosed time and medical institutes, family history, residence, previous treatment history, chief complaints at the time of admission, lesion site on chest X-ray film, combined deseases, side reaction to antibuberculosis drugs, used drugs before admission and the results of drug sensitivity test. RESULTS: The ratio between male and female was 4:1. Age showed relatively even distribution from 3rd to 6 th decades. 64.6% of the patients was diagnosed at public health center. Weight loss was the most common complaint at admission. Bilateral lesions on chest X-ray films were 59.8%. 1 30patients had combined desease, of which DM was the most common(37.7%). 95patients had family history, of which parents were the most common(41.7%). According to the time of first diagnosis, 31 patients were diagnosed before 1980, and after then the number of patients was increased by degrees Residence overwhelmed in pusan and gyung-nam province. 258 patients got previous treatment history, of which 112 patients(43.4%) had more than 3 times and only 133 patients(51.6%) got regular medication. 97 patients used more than other 3 drugs in addition to INH, EMB, RFP and PZA before admission. 154 patients were informed with the results of drug sensitivity test. of which 77 patients had resistance to more than 5 drugs. Gastrointestinal problem was the most common in side reaction to drugs. CONCLUSION: In the case of weigt loss of unknown cause, tuberculosis should be suspected. In first treatment, sufficient and satisfactory explanation for tuberculosis is necessary and treatment period should not be stict to 6 month-short term therapy. In retreatment, new drugs should not be added to used drugs enen though drug sensitivity restlts show sensitivity to some of them. Proper time for surgical intervention should not be delayed.

Autogenous costal cartilage graft has been commonly used for reconstruction of auricular deformity. However, the risk of complication and discomfort at the donor site, as well as distortion of the graft due to morphological change in the cartilage have been serious drawbacks to this procedure. Previous studies examining the chondrogenic potential of perichondrium have suggested that perichondrium may be used as graft for cartilage reconstruction. When a perichondrial flap or a free perichondrium was used as graft, new cartilage formed appositional to the grafted perichondrium. However, the neocartilage was often irregular in shape and varied considerably in quantity. In this study, the feasibility of controlling the shape and the mass of neocartilage was investigated using coral, a porous biomaterial, as a template. A coral a template was wrapped with perichondrial flap from the ears of New Zealand white rabbits and placed into a subcutaneous pocket in the rabbits and placed into a subcutaneous pocket in the rabbit's back by incision. A total of 12 animals were used. Formation of new cartilage was later evaluated by gross and histological examination of the perichondrial flap and the coral template. New cartilage was formed in 11 animals. Immature chondrocytes were visible by 3 weeks after the surgery, and by 8 weeks the immature chondrocytes had formed a cartilage. New cartilage was formed only on the surface of the coral template. These results indicated that the shape and the mass of new cartilage may be controlled by using coral template. Therefore, the desired shape of cartilage may be achieved using a coral template of corresponding shape, and this may help in correcting subtle auricular contour defect and in correcting other structural defects that also require new cartilage formation.

Postpartum hemorrhage is a common cause of maternal mortality; its main cause is placenta accreta. Therapeutic hypothermia is a generally accepted means of improving clinical signs in postcardiopulmonary resuscitation patients. A 41-year-old pregnant woman underwent a cesarean section under general anesthesia at 37 weeks of gestation. After the cesarean section, the patient experienced massive postpartum bleeding, which led to cardiac arrest. Once spontaneous circulation returned, the patient underwent an emergency hysterectomy and was placed under therapeutic hypothermia management. The patient recovered without neurological complications.

PURPOSE: To elucidate the incidence of Gd-DTPA enhancement of the optic nerve/sheath complex (ONC) in patients with various ophthalmopathies using fat-suppression MRI. MATERIALS AND METHODS: Orbit MRI with fat-suppression technique (ChemSat) was performed in 58 patients with normal and various orbital lesions. The fat-suppression MR was done with and without Gd-DTPA injection in all cases. MR findings were reviewed retrospectively in a blind fashion with respect to presence or absence of contrast enhancement of the O NC. RESULTS: Contrast enhancement of the ONC was seen in 86% (6/7) of cavernous sinus lesions, 80% (8/10) of intraconal lesions excluding the ONC, 57% (16/28) of ONC lesions, 38% (3/8) of ocular lesions, and 2% (1/55) of normal orbits. The ONC enhancement was the most common in optic nerve/sheath tumors (10/10), and pseudotumors (6/6), cavernous sinus dural arteriovenous malformations (3/3) and cavernous sinus thrombosis (2/2), and less frequently seen in optic neuritis (3/14). CONCLUSION: Enhancement of the ONC may be seen in lesions of the cavernous sinusand orbit other than optic nerve/sheath lesion.
