Fractures of the acetabulum are relatively uncommon. But if fractures of the acetubulum are not accurately evaluated, classified, and reduced anatomically, major sequalae and complications are frequently developed. Because of complicated anatomy, difficulty with surgical exposure, severe comminution, and major associated injuries, the treatment of displaced acetabular fractures between conservative and operative methods is still controversial. We reviewed thirty five cases of displaced acetabular fracture treated operaively from January 1984 to December 1991. The prevalent age was the fourth decade. There was twenty seven cases of associated injuries, twenty two dislocations of the hip. According to the Letournel's classification, the most common fracture type was posterior wall and both column type. The fracture was fixed internally with only screws in thirteen cases and with plate and screws in twenty two cases. Among thirty five patients, five patients were lost in the follow up and another five patients had followed up lesser than one year. The mean duration of follow-up afrer the operation was three years (range, one to eight years). Among twenty five patients who had followed up more than one year, the satisfactory results were achieved in nineteen patients (76%) and the poor results were achieved in three patients (8%). The complications were post-traumatic arthritis, avascular necrosis of femoral head, osteomyelitis in iliac bone, skin necrosis, and heterotopic ossification.

The kinetic of the distal radioulnar joint(DRUJ) is complex. Motion of DRUJ consists of rotation of the around the relatively stationary ulna, poisoning of the ulna along its longitudinal axis, and translational motion, which occurs in the antero-posterior plane. In addition to the motions described, there also exists and abduction-adduction movements, diastatic motion. The CT scan is an ideal tool for evaluation the DRUJ. Since it provides a coronal cross-sectional image of the radius and ulna. The amount of translational motion occurring at the DRUJ has hot been determined. To evaluate the normal boundaries of the motion of the DRUJ, forty DRUJ in twenty normal volunteers(10 meles, 10 females) were evaluated by use of a computed tomography technique. The results were as follows. 1. Average translational motion according to forearm rotation was 3.1mm±1.3. 2. There was no statistic difference between both sex(p>0.05). 3. There was no statistic difference between dominant and nondominant hand(p>0.05). The contralateral criterion is useful in determing wrist problem.

To ensure the quality and safety of Panax notoginseng, a method for the simultaneous determination of 10 mycotoxins in Panax notoginseng was developed using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with acetonitrile and purified by HLB multifunction cleanup column. The separation was performed on a Phenomenex Kinetex XB-C18 column by gradient elution using methanol and 5 mmol·L(-1) ammonium acetate as mobile phase. The targeted compounds were detected in MRM mode by mass spectrometry with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The linear relationships of the 10 mycotoxins were good in their respective linear ranges. The correlation coefficients (r) ranged from 0.9981 to 1.0000. The LOQs of the 10 mycotoxins were between 0.15 and 8.6 μg·kg(-1). The average recoveries ranged from 73.8% to 107.0% with relative standard deviations (RSDs) of 0.10%-10.9%. The results demonstrated that the proposed method was sensitive and accurate, and suitable for the mycotoxins quantification in Panax notoginseng.

PURPOSE: This study was a retrospective survey to examine economic feasibility of home care services for patients with diabetic foot. METHODS: The participants were 33 patients in the home care services (HC) group and 27 in the non-home care services (non-HC) group, all of whom were discharged early after inpatient treatment. Data were collected from medical records. Direct medical costs were calculated using medical fee payment data. Cost-effectiveness ratio was calculated using direct medical costs paid by the patient and the insurer until complete cure of the diabetic foot. Effectiveness was the time required for a complete cure. Direct medical costs included fees for hospitalization, emergency care, home care, ambulatory fees, and hospitalization or ambulatory fees at other medical institutions. RESULTS: Mean for direct medical costs was 11,118,773 won per person in the HC group, and 16,005,883 won in the non-HC group. The difference between the groups was statistically significant (p=.042). Analysis of the results for cost-effectiveness ratio showed 91,891 won per day in the HC patients, and 109,629 won per day in the non-HC patients. CONCLUSION: Result shows that the cost-effectiveness ratio is lower HC patients than non-HC patients, that indicates home care services are economically feasible.

We immunized sixty two healthy subjects with the five different viral titers (300, 500, 1000, 1500 and 2000 plaque forming unit; pfu) of the MAV/06 strain of live attenuated Varicella-zoster virus (VZV) in order to gain sufficient information on safety and immuogenicity as a vaccine strain. Humoral immunity of all vaccine recipients was tested by the fluorescent antibody to membrane antigen (FAMA) assay and Enzyme-linked immunosorbent assay (ELISA) for the quantitative detection of IgG antibody. We tested neutralized antibody in 62 subjects by plaque reduction neutralization test (PRNT50). All of thirty two subjects with initial seronegative response had antibody by FAMA method at four weeks after immunization with four different preparations of dosage. The geometric mean titers (GMTs) of VZV antibody to membrane antigen was 160.9 in 6 subjects with 1500 pfu group; 83.3 in 14 subjects with 1000 pfu group: 116.2 in 7 subjects with 500 pfu groups and 72.0 in 6 subjects with 300 pfu group. Thirty subjects who had VZV antibody at the time before immunization demonstrated elevated antibody titer by FAMA assay and PRNT50 test. Side reactions of the vaccination was not demonstrated in all cases.

9.Effect of External Environments on Urinalysis and Bacteriologic Culture.
Korean Journal of Urology 1989;30(6):871-875
The diagnosis of urinary tract infection is established by clinical symptoms and signs, urinalysis and urine culture. Urinalysis and urine culture are influenced by external environmental factors, especially temperature and time. So we have performed an assay for these effects on urinalysis and urine culture in 30 consecutive patients with urinary tract infection. Urinary specific gravity, pH and chemical components (protein, sugar, bilirubin, ketone and nitrite) were not influenced with environmental factors (temperature and time), but cellular components (RBC, WBC) were gradually decreased in number with increasing time in all temperatures without significance(p>0.06). Urine colony counts were not influenced significantly at 4 degrees C, but were increased in 4 hours at 18 degrees C and in 2 hours at 30 degrees C significantly (p<0.05). So, bacteriologic survey for urinary tract infection must be performed at least within 2 hours after collection of urine.
