Recently, the radionuclide angiocardiographic study had been enhanced by rapid development of gamma scintillation camera and computer system, and utilized as noninvasive diagnostic measurement of heart disease. We obtained the following results by the radionuclide angiocardiography with human serum albumin tagged with 99m-Technetium from two groups. One of them was congenital heart disease group(n=50, ventricular septal defect 20, atrial septal defect 6, pulmonary stenosis 2, tetralogy of Fallot 10, truncus arteriousus 1, transposition of great artery 1, patent ductus arteriosus 10) operated from Oct. 1984 to Jun. 1985, and the other was the normal human group(n=10) as control. 1) In the cases of left to right shunt, Qp/Qs values were calculated by th gamma variet fit curve. The preoperative values ranged from 1.441-3.00, the postoperative values were normal among all the patients except one(atrial septal defect, postop. Qp/Qs 2.335). 2) In the cases of right to left shunt, Qp/Qs values showed no apparent change between pre. andpostoperative period, possibly due to still remained collateral circulation and hardly obtained lower value(less than QP/QS 1.0) by computer system, But the double peak curve was noticed in the left ventricular time activity curve, which indicate right to left shunt, disappeared after the surgery, suggesting shunt closed. 3) The ejection fraction of left ventricle was obtained from the congential cardiac patients, ranged 0.38-0.65 before the surgery and 0.41-0.67 after the surgery. 4) The circulation time calculated from the first-pass radionuclide angiocardiography, ranged normal in the most congenital cardiac patients, but prolonged in the severe pulmonary hypertension.

Osteochondrodysplasia is a heterogeneous group of disorders appearing short limbed dwarfism. Because many of these entities are lethal and hereditary, an accurate diagnosis is mandatory. The purpose of this study is to define the clinicopathologic features and radiologic findings of osteochondrodysplasia. We reviewed 29 autopsy cases of congenital short limbed dwarfism, consisting of thanatophoric dysplasia (TD) (12 cases), osteogenesis imperfecta (OI) (12 cases), asphyxiating thoracic dysplasia (ATD) (3 cases), short-rib-polydactyly syndrome (SRPS) (1 case) and hypochondrogenesis (1 case). The gestational age ranged from 16 to 41 weeks. Of 6 fetuses that were born alive, 3 were ATD, 2 were TD and 1 was hypochondrogenesis. TD was frequently complicated by hydramnios. Of 8 cases studied chromosomally, only 1 showed chromosomal abnormality -46XY, inv 9. Intrauterine growth retardation was frequently associated with OI. Pulmonary hypoplasia was present in 23 cases (79%), including all cases of ATD, SRPS and hypochondrogenesis, 11 in TD and 7 in OI. Other associated anomalies were present in 17 cases (59%).

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.

Entrapment neuropathy of the suprascapular nerve is rare and frequently overlooked in the differential diagnosis of shoulder pain. There have been few published reports on a ganglion compressing the suprascapular nerve. We experienced a case of entrapment neuropathy of the suprascapular nerve by a ganglion that compressed the inferior branch of suprascapular nerve at the spinoglenoid notch.

To define the basic sequential events of the healing process in normal fracture and evaluate the role of growth regulatory molecules and extracellular matrix components, the expression of transforming growth factor β(TGF-β), platelet-derived growth factor(PDGF), type I and II collagen, and chemistry during the healing process of an experimental fracture of tibia in 41 adult rats for 7 weeks using ABC methods. The phases of inflammation, reparation, and remodeling followed each other in sequence. The inflammatory phase was characterized by hemorrhage, edema, and infiltration of inflammatory cells on the first day. During the reparative phase, the undifferentiated mesenchyme undergoes rapid chondrogenesis, followed by endochondral ossification and supplemented by appositional bone formation. At day 3, the expression of TGF-β and PDGF was noted in the undifferentiated mesenchymal cells and from day 5, these two growth factors were detected in the osteoblasts and extracellular matrix in areas of endochondral ossification and newly formed periosteal bone. From day 3, the expression of type I collagen and osteonectin was noted in the osteoblasts and extracellular matrix in both endochondral ossification and appositional bone growth as a marker of ossification. From day 3, type III collagen was mainly expressed in the plump mesenchymal cells showing chondroid differentiation and chondroid matrix as a marker of cartilaginous reparative phase. From day 14, these growth factors and extracellular matrix components were decreased in staining intensity and at the 5th week, the histology and immunostaining pattern were similar to the mature bone.

8.Cutoff Serum Prostate Specific Antigen Values by Age Decade in Men Clinically Free from Prostate Cancer.
Korean Journal of Urology 1994;35(10):1080-1085
In order to define PSA levels by age decade in men without clinical evidence of prostatic adenocarcinoma, so called non-cancer, Tandem-R assay for PSA was performed in male patients older than 40 years who had visited to our department. We defined the non-cancer population as men with a normal PSA value( 4.0ng/ml or less) and negative digital rectal examination findings. Furthermore, patients with an abnormality in either PSA value or suspicious digital rectal examination underwent transrectal ultrasound and pathologically excluded prostatic cancer from the population by transrectal prostate biopsies or transurethral resection. A total of 203 men entered the protocol, of whom 192 satisfied our criteria of non-cancer population. New mean, standard deviation and cutoff serum PSA values by age proposed as mean + 2 standard deviations were derived as follows, 0.84 0.68ng/ml( 2.2ng/ml) in the 40 to 49-year group, 2.03 + 1.36ng/ml( 4.8ng/ml) in the 50 to 59-year group. 2.02 + 1.7lng/ml( 5.4ng/ ml) in the 60 to 69-year group, 3.16 + 1.91ng/ml( 7.0ng/ml) in the 70 to 79-year group and 4.52 + 4.03ng/ml(12.6ng/ml) in the 80 to 89-year group.

PURPOSE: To evaluate the causative factors of the false positive CT findings of parametrial invasions of cervial cancer. MATERIALS AND METHODS: we analysed 17 parametria of 14 patients with the diseases staged over lib on CT, but confirmed to be under stage Ila on pathology. The CT findings were retrospectively reviewed, and compared with pathologic findings. RESULTS: The causes of false postive diagnosis of parametrial invasions on CT were prominent cardinal ligaments (n=12), vaginal fornix(n=3), and prominent uterine vessels(n=2). CONCLUSION: Familiarity with these CT finding may be helpful in avoiding false positive diagnosis of parametrial invasion in patients with uterine cervical carcinoma.

Invasive infection of the Streptococcus bovis group in a neonate is rare. In cases reported to date, the pathogen of neonatal S. bovis infections is usually Streptococcus gallolyticus subsp. pasteurianus (S. bovis biotype II/2). Streptococcus lutetiensis (S. bovis biotype II/1) was identified using 16S rRNA and tuf gene sequence analysis of the isolates from blood and cerebrospinal fluid (CSF) of a fever-presenting 28-day-old male. Blood culture analysis was performed using automatic equipment (VITEK 2) and identified Streptococcus infantarius supsp. infantarius, yet we were unable to get accurate results from the CSF culture. The fever subsided on the second day of hospitalization, and the patient was discharged without neurologic complication after 14 days of antibiotic therapy. In this case, we were able to accurately identify the pathogen using molecular genetic methods. To our knowledge, this is the first case of late onset neonatal bacteremia and meningitis caused by S. lutetiensis.
