Percutenous transluminal angioplasty is world wide prevalent method for treatment of vascular occlusivedisease. Its advantage is avoidance of major surgery as well as decreased cost with shortened hospital days. Inrenal arterial stenosis, successful angioplasty produces draumatic reduction of blood pressure in renin dependent hypertension. Even in renin independent hypertension, blood pressure may be easier to control withantihypertensive medication following renal arterial dilatation. We have performed 2 cases of percutaneous transluminal angioplasty in renal arterial stenosis recently. One patient, 58-year-old female, has gained normalblood pressure after angioplasty, while the other showed not very satisfactory blood pressure control because ofchronic bilateral renal parenchymal damage.

Although several kinds of instrumentation systems are available for the transpedicular screw fixation in the treatment of spondylolisthesis, the clinical results and the difference between them remdins unclear. In order to study the feasibility of Zielke instrumentation system for that purpose, the author analysed the clinical results of 73 patients with mild or moderate degree of spondylolisthesis who were instrumented with the systems and followed up 25 months in average(Min. 12Ms). The results between the groups with different rod thickness in the system, 3.2mm(20 patients), 4mm(33 patients) and 5mm(20 patients), were compared to study the most appropriate thickness. Reduction of the deformity were done by aid of temporarilly applied Harrington system in 3.2mm group. Inlayed reduction potential coming from the jointing mechanism was utilized in the cases with less than 30% of slippage in 4 and 5mm group. Percentage of slippage was changed from 20% preoperatively, to 4% postoperatively and 6% at the end of follow up. The methods of fusion after reduction and fixation were anterior in 25 and posterolateral in 48. Bony fusion was achieved in all but one with pathological spondylolisthesis. Rod failures were observed in two of 3.2mm and one of 4mm group, and loosening of the joint were developed in three of 5mm group. Clinically, 93% of the patient showed excellent and good results at the end of follow up. From the results, we concluded that the instrumentation is a efficient method of treatment with several advantages in the reduction capacity and the stability of fixation. However, this system has several points in its mechanics that needs to be improved.

Congenital tuberculosis is an infection that is established in the fetus by hematogenous spread or by the aspiration or inhalation of infected amniotic fluid either before or during labor. The diagnosis can be confirmed only if both the tuberculous nature of the lesion and the antenatal origin of the infection can be proved. The authors analysed roentgen findings of two cases of pulmonary tuberculosis, thought to be congenital; 1. Diffuse distribution of nodular densities and some confluent densities were seen in the entire lungs in the inital film.The pulmonary markings were decreased in some degree. 2. Air bronchogram was noted. 3. Hepatosplenomegaly was associated.

Since the reservior of leptospires organism is consisted of a broad spectrum of animals, the best method of prevention is vaccination. The clinical trial of leptospires vaccine conducted on human volunteer for its immunogenicity and safety. Summarized results are as follows: 1. The Oral temperature among vaccinated group ranged from 36.7 +/- 0.34 degrees C, while in placebo injected group it ranged from 36.4 +/- 0.46 degrees C to 36.7 +/- 0.53 degrees C. There wan no association between vaccination and fever (p<0.05). 2. Mild local reactions revealed in vacciness were swelling (50-75%), Redness(75-90%), and induration(25-40%). Placebo injected group revealed only redness in 12.5% in the 1st injection and 37.5% in the second injection. The duration local reactions on injection site for both vaccinees and placebo groups disappeared within 48 hours. 3. Generalized Symptoms complained by the vaccinees were myalgia (25%), back pain(15%), headache(15%), pruritus(15%), and abdominal pain(10%), whereas placebo group complained of headache(25%), myalgia(12.5%), back pain(12.5%), pain in eyes(12.5%), abdominal pain(12.5%) prutitus(12.5%) and nausea(12.5%). 4. The serological test(MAT) of vaccinees showed geometric mean antibody titer as follows: a. L. icterohemorrhagiae lai, 1 week after 1st vaccination: 22.45, 1 week after 2nd vaccination: 111.23, 3 week after 2nd vaccination: 266.64, b. L. canicola canicola, 1 week after 1st vaccination: 24.62, 1 week after 2nd vaccination: 123.92, 3 week after 2nd vaccination: 276.55, c. L. icterohemorrhagiae copenhageni, 1 week after 1st vaccination: 28.28, 1 week after 2nd vaccination: 128.55, 3 week after 2nd vaccinaton: 247.88, Whereas all of the placebo injected group, showed below 1 : 20 titers. The sero-conversion rate of vaccinees were 100 percent.

A parasitological study was performed with 452 malaria patients evacuated from South Vietnam by examinations of their peripheral blood. Results were as follows: The peripheral blood examinations revealed that 52.0% of the examined have parasitemia, of which 95.3% was P. falciparum, one case of P. vivax and the other 10 patients were mixed infected. Neither P. malaria nor P. ovale were found. A total of 1,500 thick and thin blood films was prepared and 707 slides of them (47.1%) showed positive. In P. falciparum, ring forms were found most frequently and the next was gametocytes. Eighty slides (50%) showed mixed together with both ring form and gametocytes. All of the erythrocytic stages were seen in three slides of P. vivax. Weekly periodical examinations showed 233.8 parasite density every 1,000 W.B.C count in average, while occasional at fever attacks 531.7.Size of gametocytes in P. falciparum was 9.31(+/-0.89) by 2.16(+/-0.53) in macrogametocyte and 6.61(+/-0.82) by 2.51(+/-0.35) in microgametocyte. Their sex ratio was 100 : 92. Repeated blood examinations showed increased detection rates. The positive rate of parasitemia was 52.0% in single examination, increasing in succession with repetitions.

Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal function are not evaluated with there methads. 99mTc-DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75 kidndys of 67 patients with confirmed renal tuberculosis. We classified the morphologies of tuberculous kidneys as 6 types. We classified the morphologies of tuberculous kidneys as 6 types such as the type with small cortical defect, with parenchymal ulcerocavernous lesions, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspondings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates were 19.0%, 18.4%, 7.9%, 12%, 4.1%, 3.4% respectively.

This is a case report of a 5-month-old male who was brought in to hospital for evaluation of jaundice from birth. The baby had a history of ileal atresia operated 2 days after birth. At the age of one month, Tc-99m DISIDA hepatobiliary scintigraphy was performed at other hospital and reported to show good hepatic uptake of the tracer but no uptake in the billiary tree, gall bladder, or intestine for 24 hours post injection. He was judged to have biliary atresia. However, subsequent exploratory laparotomy revealed that the hepatobiliary tree appeared intact and that there was a gall bladder. Additionally, the patient had central aorto-pulmonary shunt for the right ventricular septal defect with pulmonary stenosis of a peripheral type at the age of 4 months. The second hepatobiliary scintigraphy was performed on admission at the age of 5 months, showing a gall bladder but no intestinal uptake up to 24 hours. Retrospectively, the histological specimen of the liver obtained at the exploratory laparotomy was re-evaluated, and by the histological findings coupled with clinical data, arteriohepatic dysplasia (Alagille's syndrome) was diagnosed. In this report, we emphasize the diagnostic limitation of hepatobiliary scintigraphy and the importance of overall clinical and histologic evaluation in a case of Alagille's syndrome.
