Illuminating type poster looks very impressive and one may feel as if it were on the view box in his readingroom. Some difficulties and nuisances really exist in making them and a few of demerits can also be encounteredthat of contrast enhancement and of rough graininess. Contact print renders the best quality, though, KodakTechnical-Pan film with HC-110 (Dil. F) developer, llford xp 1–400 with Kodak C-41 color developer and KodakPlus-X with Microdol-X developer combinations also work in minimizing the deterioration of resolution and grainisswhich can almost always occur in enlargement prints.

Pecutaneous transhepatic portogram with selective catheterizatio of the portal vein and its tributaries notonly provide information about the status of portal circulation and but can also be used in the treatment ofbleeding esophageal varices by selective embolization with various embolic materials. The authors describe easierand safer modified method of conventional percutaneous transhepatic portogram. We wish to describe our experiencewith the technical aspects and portosystemic collateral patterns in 26 patients with variceal bleeding, from July1985 to July 1986 at Kyungpook National University Hospital. 1. To overcome the difficulties of catheter passageand superselection of variceal supplying vein, we used 7F sheath directly introduced over the ,018″ guide wire.We used coaxial system using 25cm 18G needle within 7F vessel dilator to make the tip of dilator more rigid. 2.Variceal obliteration attempted in 23 patients who showed variceal supplying veins on the protogram, Successfulobilteration was obtained in 20 patients. We used absolute ethanol, stainless steel coil, and Gelfoam cubes withsclerosing and embolica agent of variceal vein. 3. Portosystemic collaterals of 24 patients; Coronary vein;21cases, Inferior mesenteric vein:9 cases, Short gastric vein:7 cases, Umbilical & paraumbilical vein; 6 cases,Gastrorenal: 3 cases, Splenorenal: 2 cases, Splenoretoperitoneal: 1 case. 4. The number of coronay vein were 18cases of single and 4 cases of two. The locations of coronary vein: Splenic vein: 13 cases, Main portal vein: 7cases, Junctional area: 6 cases. 5. Transhepatic obliteration of the gastroesophageal veins is a relatively simpleand usually successful form of palliative treatment for actively bleeding and stable gastroesophageal varices.

A primary skin adenoid cystic carcinoma first described by Boggio in 1975, is one of the rarest type of eccrine sweat gland carcinoma. Histologically, a tumor with typical morphologic features closely resembles adenoid cystic carcinoma was found in other tissues but in the skin must be distinguished from aggressive basal cell carcinoma. The natural history of this tumor is not yet fully determined but suggests a long indolent and progressive course. We report a case of a 77-year-old male with a small skin nodule in the abdomen.

PURPOSE: Congenital Iobar agenesis of the liver is a rare anomaly. We report five cases (three cases of right Iobar agenesis and two cases of left Iobar agenesis) and discuss the radiologic findings of this congenital anomaly. MATERIALS AND METHODS: Between July, 1992 and February, 1993, three cases of right Iobar agenesis and two cases of left Iobar agenesis of the liver were diagnosed by means of computed tomography(CT) and/or sonography. MR imging was performed in two patients, cholangiography in two, and digital subtraction angiography in one. RESULTS: The main findings of right Iobar agenesis of the liver were nonvisualization of the right portal vein and absence of liver tissue to the right of gallbladder. The findings of left Iobar agenesis were nonvisualization of left portal vein, absence of liver tissue to the left of the gallbladder, and absence of ligamentum teres. The ancillary finding of the Iobar agenesis was visualization of less than three hepatic veins. CONCLUSION: It is important to consider Iobar agenesis of the liver in differential diagnosis when imaging studies reveal abnormal portal vein branches, unusual position of gallblader, absence of ligamentum teres, and visualization of less than three hepatic veins.

sodium hyaluronate in beagle dogs. METHODS:In group 1, hGH(Eutropin, r-hGH) 0.29mg/kg was injected subcutaneously to 6 beagle dogs everyday for 7 days. In group 2, 1mg/kg in sustained- release formulation using sodium hyaluronate(SR-hGH), was injected subcutaneously to 6 beagle dogs. In group 3, 2mg/kg of the same formulation(SR-hGH) was injected subcutaneously to 6 beagle dogs. Blood samplings were done for the measurement of GH and IGF-1 concentrations with ELISA kit(Diagnostic Systems laboratories, Inc., USA) RESULTS:GH concentration in group 1 was below 0.5ng/ml before injection and elevated to 98.1+/-15.7 at 1 hr, 124.2+/-15 at 2 hr, 57.8+/-18.1 at 4 hr, 23.8+/-4.8 at 6hr, 10.8+/-3.7 at 8 hr, 2.8+/-1.6 at 10 hr, 1.0+/-0.7 at 12 hr, and 0.5+/-0.1ng/ml at 24hr after injection. Peak GH concentration was observed in 2 hr and thereafter decreased progressively and returned to basal level at 10 hr after injection. From the 2nd day GH concentration was measured only at 6 hr after daily GH injection, indicating the values of 20.9+/-8.7, 16.2+/-14.9, 23.1+/-8.5, 34.3+/-9.9, 16.1+/-7.0, and 21.8+/-13.0ng/ml at 2nd, 3rd, 4th, 5th 6th, and 7th day, respectively. GH concentrations in group 2(SR- hGH 1mg/kg) were 136.7+/-22.8 at 1hr, 149.3+/-29.9 at 2hr, 110.6+/-17.8 at 4hr, 103.7+/-18.2 at 6hr, 108.3+/-21.0 at 8hr, 91.4+/-21.4 at 10hr, 79.6+/-15.9 at 12hr, 23.7+/-8.3 at 24hr, 5.5+/-1.5 at 30hr, 0.7+/-0.2 at 48hr, 1.4+/-1.4 at 54hr, and 0.5+/-0.1ng/ml at 72hr after injection. GH concentration was elevated above the basal level for 72hr with the peak at 2hr after injection of SR-hGH of 1mg/kg. GH concentrations in group 3(SR-hGH 2.0mg/kg) were 196.7+/-45.2 at 1hr, 219.4+/-39.8 at 2hr, 198.1+/-38.0 at 4hr, 196.0+/-31.4 at 6hr, 179.2+/-28.3 at 8hr, 151.8+/-19.5 at 10hr, 141.3+/-23.1 at 12hr, 72.9+/-14.7 at 24hr, 43.7+/-14.2 at 30hr, 3.8+/-1.6 at 48hr, 1.6+/-0.5 at 54hr, 0.8+/-0.5 at 72hr, 0.5+/-0.1 at 78hr, and 0.5+/-0.2ng/ml at 120hr. Peak GH concentration occurred at 2hr after injection and remained high concentration till 72hr and returned to basal level thereafter. IGF-1 concentrations in group 1 changed from 190.5+/-68.1ng/ml before injection, to 326.4+/-96.2, 346.4+/-79, 391.4+/-86.9, 417.0+/-96.1, 422.1+/-92.0, 429.9+/-86.4, and 478.0+/-90.2ng/ml at 12hr, 30hr, 54hr, 78hr, 102hr, 126hr, and 150hr, respectively. IGF-1 concentrations in group 2 were 128.5+/-37.0 ng/ml before and 268.0+/-64.2, 307.6+/-63.1, 374.8+/-55.3, 335.5+/-39.4, 301.9+/-44.8, 288.5+/-42.5, 272.8+/-51.8, 273.9+/-46.0, 251.1+/-40.9, and 239.2+/-45.0ng/ml at 24hr, 30hr, 48hr, 54hr, 72hr, 78hr, 96hr, 102hr, 126hr, and 150hr, respectively after injection. Peak IGF-1 concentration was measured at 48hr and remained in high concentration till 150hr after injection. IGF-1 concentrations in group 3 were 116.0+/-68.9ng/ml before and 365.5+/-118.6, 400.0+/-135.1, 463.6+/-138, 450.2+/-140.0, 337.2+/-122.4, 301.4+/-113.4, 236.3+/-89.1, 226.3+/-75.5, 148.9+/-55.2, and 129.8 48.4ng/ml at 24hr, 30hr, 48hr, 54hr, 72hr, 78hr, 96hr, 102hr, 126hr, and 150hr, respectively after injection. Peak IGF-1 concentration was at 48hr and remained in high concentration till 150 hr after injection. There was no significant difference in IGF-I conc between group I and group 3. CONCLUSION: Sustained-release form(1mg or 2mg/kg) of hGH with sodium hyaluronate released GH for 72 hours with the peak level at 2 hours and higher concentration of IGF-I above baseline maintained for 150 hour after injection with peak level at 48 hour. There was no difference in IGF-1 concentration between SR-hGH 1mg/kg and 2mg/kg injection. So sustained release form 1mg/kg will be more effective for GH therapy as weekly injection mode. More extensive study is needed to permit for new therapeutic application.

PURPOSE:Growth hormone(GH) therapy is very effective for the treatment of short stature, but it is unconvenient that GH should be injected daily because of short half-life. Sustained-release forms of GH preparation is needed for better compliance. This study aimed to measure peak pattern and duration of release of hGH from solid microparticles using sodium hyaluronate. METHODS:In group 1, hGH(EutropinTM) 285microg/kg was injected subcutaneously to 2 Jindo dogs everyday for 7 days. In group 2, hGH solution(EutropinTM) was continuously infused subcutaneously for 12 hours a day for the first 2 days via mini pump(minimed co.) and then for 24 hours a day thereafter until 7th day with the rate of 11.9microg/kg/hr. In group 3, dose of 2mg/kg hGH in sustained-release formulation using sodium hyaluronate, was injected subcutaneously to 3 Jindo dogs. In group 4, two dose levels of 1mg/kg and 2mg/kg hGH in sustained-release formulation using sodium hyaluronate, were injected subcutaneously to each group of 4 Beagle dogs. To evaluate side reactions from continuous injection of sodium hyaluronate, sustained release form of hGH 2mg/kg was injected to 4 Beagle dogs once a week for 4 weeks and compared to 4 control Beagle dogs. Blood samples were withdrawn half- hourly for 6 hour and 2-4 times a day thereafter in Jindo dogs and at 6hr, 12hr, 22hr in the first day and twice a day(at 9:00, 16:00 O'clock) for the following 6 days. RESULTS:In group 1, peak GH conc. of 122+/-27ng/ml was observed at 1 hour after hGH(EutropinTM) 285microg/kg injection and 1/2 of peak GH conc. at 4 hour. and decreased to 2ng/ml at 24 hour. GH AUC(Area under curve) was 670(ng/ml.hr). In group 2, initial steady state GH conc. of 25ng/ml occurred after 6 hour, however, GH conc. decreased gradually to 16ng/ml at the 7th day. GH AUC based on th initial steady state GH conc. was 600(ng/ml.hr). In group 3(Jindo dogs), GH conc. was peaked at 12 hour and 1/2 of peak GH conc at 30-46 hour and decreased to baseline at 70 hour. GH AUC was 2173(ng/ml.hr). In group 4(Beagle dog), peak GH concentrations of 56+/-7ng/ml and 108+/-12ng/ml were observed at 12 hour for the doses of 1mg/ kg and 2mg/kg, respectively and 1/2 of peak GH conc at 48 hour and decreased to baseline at 80 hour. GH AUC was 3560(ng/ml.h) for 2mg/kg treated dogs. Serum IGF-1 was increased to peak levels of 520ng/ml, and 580ng/ml for the doses of 1mg/kg 2mg/kg, respectively, and persisted above the baseline till 120 hour. There was no specific side reaction during experimental period. CONCLUSION: Sustained-release form of hGH with sodium hyaluronate released GH for 70-80 hour with the peak level lower than that resulted from the conventional aqueous formulation of the equivalent dose, and higher concentration IGF-I maintained for 120 hour after injection above baseline. More extensive study is needed to permit for new therapeutic application.

We present 3 cases of congenital hyperplasia. Case lis a 5 year and 9 month old who is suffered from excessive salt craving and symptoms of precocious puberty. Case llis a 2 month old boy who has failure to thrive and frequent episode of dehydration. Case lll is a 5 year and 3 month old girl who has enlarged clitoris without salt craving since birth. All 3 cases have higher level of 17KS than normal but normal blood pressure. Serum 17 OH progesterone or urinary pregnanetriol were not checked. All patients were well responding with corticosteroid and 17 KS in 24 hour urine were decreased to normal. These patients are considered to have 21 hydroxylation defect type in congenital adrenal hyperplasia. Review of literature and references on congenital adrenal hyperplasia was attempted priefly.

The components of bore marrow change dramatically during lifetime. To evaluate the bone marrow of cranium and upper cervical spine, the authors retrospectively evaluated 300 examinations of cranium and the second cervical bone in patients without known bone marrow abnormality. T1-weighted images were used to analyze the changes of lone marrow signal intensity according to the age and sex. The signal intensity of bone marrow of cranium increased most rapidly from birth to age of 10 years. Between 11 and 20 years of age, gradual increase of signal intensity was noted. There was minimal augment of signal intensity after age of 20 years. The examination of signal intensity of bone marrow of the cranium revealed slightly higher score in male than in female. The synchondrosis of the second cervical vertebra was visible in 97%. These results may be useful in the detection of abnormal bone marrow signal of cranium and upper cervical spine.
