Three cases of spondyIolysis were experienced and treated by anterior interbody fusion of the involved spines at the department of orthopaedic surgery in the Taegu Hospital One case was accompanied with severe lumbago with radiating pain and other two cases with lumbago significantly. Review of literature was done with report of three cases of spondylolysis.

The effect of elevated mixed venous oxygen tension(PvO2) on the diffuse alveolar hypoxia was studied in dogs using venovenous(VV) extracorporeal lung assist(ECLA). Six mongrel dogs were mechanically ventilated with the continous infusion of pentobarbital. A double lumen tube was inserted via the right external jugular vein and was eonnected with the ECLA cireuit to establish a VV bypass. A Kurare oxygenator 0.3m2 was chosen to obviate the use of homologous blood for priming. The total volume of the ECLA circuit was 150mL Without ventilating the oxygenator during VV ECLA, we decreased F1O2 from 0.21 to 0.1 via 0.15 to evaluate the hypoxic repsonse of lung. Stepwise reductions in F1O2 0.21 to 0.l caused the arterial oxygen tension(PvO2) and (PvO2 to decrease while the mean pulmonary arterial pressure(MPAP) and pulmonary vascular resistance(PVR) progressively increased. We hypothesized that the reduction of F1O2 without aceompanying decrease of PvOmight not induce hypoxic pulmonary vasoconstriciton(HPV) which was proved at low F1O2 with low PvO VV ECLA was tried on another 7 dogs while monitoring arterial oxygen saturation(SaO2) and mixed venous oxygen saturation(SvO2) by two oximetrix catheters. The elevation of SvO2 during VV ECLA was followed by the elevation of SaO2 We compared MPAP and PVR at high F1O2 with those at low F1O2with VV ECLA while making SaO2 equal. PvO2 were 39+/-11mmHg at F1O2 0.21 and 62+/-11mmHg at F1O2 0.15 with VV ECLA. PvO2 were 30+/-8mmHg at F1O2 0.15 and 53+/-10mmHg at F1O2 0.1 with VV ECLA. MPAP and PVR were 18+/-5mmHg and 176+/-56 dyne sec/cm5 at F1O2 0.21 and 19+/-4mmHg and 198+/-94 dyne sec/cm5 at F1O2 0.15 with VV ECLA . MPAP and PVR were 25 5 mmHg and 430+/-250 dyne. sec/ cm5 at F1O2 0.15 and 25+/-5mmHg and 400+/-197 dyne sec/cm5 at F1O2 0.1 with VV ECLA. Decrease of F1O2 from 0.21 to 0.15 and from 0.15 to 0.1 did not cause significant ehanges in MPAP and PVR during VV ECLA. Our findings indicate that small increase of PvO2 by VV ECLA may prevent or diminish hypoxic resyonse of the whole lung.

OBJECTIVE: Duchenne muscular dystrophy(DMD) is a X-linked recessive disease and results from mutation in the dystrophin gene. In this study, we evaluate the efficacy of polymerase chain reaction-restriction fragment length polymorphism in prenatal genetic diagnosis of DMD. METHODS: DNA was isolated from DMD family's blood and fetal amniocyte and used to perform PCR-RFLP. In DMD family(3 cases), linkage analysis was tried with 5 RFLP probes. RESULTS: DMDs of the family A had mutiple exon deletions(6, 8, 12, 13, 17). The mother was a heterozygote of pERT84;MaeIII. The male fetus had a same allele and also same exon deletions with the affected males. The pregnancy was terminated at IUP 18 gestational weeks. Pregnant woman of the family B was heterozygote of both pERT84;MaeIII and pERT87-15;BamHI, and pregnant woman of the family C was of pERT84;MaeIII. The both male fetuses , as compared with the affected male of each family, had a different allele. Thus, the fetuses were probably not affected with a confidence level of 95%. CONCLUSIONS: Prenatal diagnosis in prevention of DMD is most important. PCR-RFLP analysis in DMD family is rapid and useful diagnostic tool.

BACKGROUND: Resuscitation following bupivacaine-induced cardiovascular collapse is difficult and often refractory to conventional treatment. This study was performed to assess the effect of insulin on bupivacaine-induced cardiovascular collapse in pentobarbital-anesthetized rabbits. METHODS: Bupivacaine was administered at 0.75 mg/kg/min until the heart rate decreased to 65 beats/min. A bolus of regular insulin (2 U/kg) was administered intravenously at the bupivacaine infusion endpoint (BIE) in the insulin group (n = 8), and 2 mL of 0.9% NaCl was administered to the control group (n = 8). RESULTS: All animals in the insulin group survived and four animals died in the control group. Arrythymia was rare 10 minutes after the BIE in the insulin group. CONCLUSIONS: Bupivacaine-induced cardiovascular collapse can be effectively reversed with an insulin injection, probably through facilitation of cardiac conduction and contraction.

PURPOSE: The purpose of this article is to study whether the Doppler ultrasound differentiate obstructive hydronephrosis from nonobstructive hydronephrosis in sonographically diagnosed hydronephrosis. MATERIALS AND METHODS: We studied 35 kidneys of 27 patients with hydronephrosis which were diagnosed with sonography. Resistive indices were calculated from Doppler waveforms at the level of interlobar or arcuate arteries. We divided the materials into two groups with obstructive and nonobstructive hydronephrosis according to the findings of intravenous pyelography, retrograde pyelography, and anterograde pyelography. These were compared with normal control group(20 kidneys in 10 persons). We also grouped patients regarding to the duration after onset of clinical symptom, and graded the hydronephrosis into three group according to sonographic findings. We analyzed the correlations of the above sonography and clinical findings with resistive index. Hydronephrosis was obstructive in 20 kidneys(in 17 patients) and nonobstructive in 15 kidneys(in 10 patients). RESULTS: There was statistically significant difference between the mean resistive indices in obstructive hydronephrosis(0.74 +/- 0.02) and that in nonobstructive hydronephrosis (0.60 +/- 0.02)(p<0.05). Also there was no difference between the mean resistive indeces in nonobstructive hydronephrosis and that in normal control group(0.59 +/- 0.07)(P > or = 0.05). CONCLUSION: The use of Doppler sonography can be helpful in detecting the presence or absence of true obstruction in patients with hydronephrosis.

Methotrexate (MTX) has been widely used in the treatment of psoriasis and rheumatoid arthritis. But prolonged use of MTX can induce hepatic fibrosis and even cirrhosis. To date, in Korea, there have been very few reports on hepatotoxicity due to MTX, and no report on biopsy-proven chronic active hapatitis. We report one patient who developed chronic acitve hepatitis while taking long-term daily dose of MTX(10mg per day) for psoriasis for a prolonged period.

The authors devdeloped a computer program for automatic coding of ACR (American College of Radiology) code. The automatic coding of the ACR code is essential for computerization of the data in the department of radiology. This program was written in FoxBASE language and has been used for automatic coding of diagnosis in the Deparment of Radiology, Wallace Memorial Baptist Hospital since May 1992. The ACR dictionary files consisted of 11 files, one for the organ code and the others for the pathology code. The organ code was obtained by typing organ name or code number itself among the upper and lower level codes of the selected one that were simultaneously displayed on the screen. According to the first number of the selected organ code. the corresponding pathology code file was chosen augomatically. By the similar fashion of organ code selection, the proper pathologic dode was obtained. An example of obtained ACR code is "131.3661". This procedure was reproducible regardless of the number of fields of data. Bacause this program was written in "User's Defined Function" from, decoding of the stored ACR code was achieved by this same program and incoporation of this program into another data processing program was possible. This program had merits of simple operation, accurate and detail coding, and easy adjustment for another program. Therefore, this program can be used for automation of routine work in the department of radiology.
