  • We report a case of 33-year-old man with a transient splenic uptake who had traumatic multiple rib fractures and hernoperitoneum combined with underlying liver cirrhosis, liver cirrhosis with liver bed laceration and splenomegaly without any other demonstrable splenic lesion due to traffic accident was found by abdominal ultrasound and surgery. Incidentally, $^{99m}Tc$-MDP Bone scan showed whole prominent splenic uptake, spleen was also visible on $^{99m}Tc$ Tin colloid liver scan. We suggest the splenic uptake of the radionuclide temporary splenic infarct to the transient total splenic infarction or unknown traumatic effect.

  • Purpose: Tc-99m MDP bone scan was performed to evaluate a generalized bone pain in a 24-year-old male chronic myelogenous leukemia patient who received bone marrow transplantation at 7 months ago. The patient had received large amounts of blood transfusion for managing symptoms related to anemia. Bone scan revealed substantial splenic tracer uptake. Magnetic resonance image and laboratory evidence of hemochromatosis suggests that the presence of large quantities of iron in the spleen of this patient may have been responsible for the splenic uptake of the bone scanning agent. The authors report a case of splenic hemochromatosis incidentally found on Tc-99m MDP bone scan.

  • Hepatoscintigram has been a useful diagnostic method for the liver diseases since 1953, but reasonable diagnostic criteria for parenchymal liver diseases are not yet accurately established. For the purpose of searching for more advanced diagnostic criteria for various types of live disease by the liver scan, a retrospective study was made of 272 cases who underwent both hepatoscintigram with 198 Au colloid and liver biopsy in Hanynag University Hospital from Jan., 1978 to Dec., 1981. The results were as follows: 1. Fuzzy margin (irregular indentation of the liver margin) in the hepatoscintigram was noted in 226 cases (97.79%). 2. Of 35 cases with fuzzy margin only, 28 cases (80%) revealed mild parenchymal liver disease, such as acute hepatitis or chronic persistent hepatitis by the liver biopsy. 3. Mottling change (209 cases) was always accompanied by fuzzy margin except only one case, and 31 cases (86.1%) of fuzzy and mottling cases (36 cases) showed mild parenchymal liver disease. 4. Configuration change (193 cases) was usually accompanied with other changes and espicially 104 cases had configuration change with fuzzy and mottling changes. 73 cases (88.44%) of 86 cases with severe configuration change revealed advanced parenchymal liver disease on biopsy. If liver scan showed mild configuration change, we could not decide the type of liver disease only liver scan, and so further studies are needed. 5. Splenic uptake was noted in 34 cases (40.48%) of 84 cases with advanced parenchymal liver disease, and the degree of splenic uptake was for the most part morderate or severe; whereas splenic uptake was noted in 18 cases (16.51%) of the mild parenchymal liver disease (109 cases), and the degree of splenic uptake was largely mild.

  • Technetium-labeled phosphate bone scan was shown to detect bone fractures and bone metastasis in early stage than general radiographs. Therefore, bone scan has become one of the most frequently performed nuclear medicine imaging examination. However, non-osseous radiopharmaceutical uptake on the bone scan are unusual findings. We report a case of diffuse splenic absorption of Tc-99m dicarboxypropane diphosphonate in patients who undergo liver transplantation.

  • We report a case of hepatoma which had a suggested splenic metastasis in a 64 year-old male patient. Hepatoma proved by abdominal CT (Computed Tomography) and considerable accumulation of $^{99m}Tc$-DISIDA was noted in a enlarged spleen. We suggests the splenic uptake of the radionuclide corresponded to the diffuse metastasis of hepatoma to spleen.

  • In an endeavor to help understand some typical scan findings and portal hemodynamics in liver cirrhosis, several commonly occurring scan changes and esophageal varices as demonstrated by esophagram were correlated one another from quantitative and qualitative stand points. Clinical materials consisted of 34 patients with proven diagnosis of liver cirrhosis and esophageal varices. Liver scan was performed with colloidal 198-Au and the changes in the size and internal architecture of the liver, splenic uptake and splenomegaly were graded and scored by repeated double-blind readings. The variceal changes on esophagrams were also graded according to the classification of Shanks and Kerley following modification. Of 34 patients, 91% showed definite reduction in liver volume (shrinkage) constituting the most frequent scan change. The splenic uptake and splenomegaly were noted in 73.5 and 79.4%, respectively. The present study revealed no positive correlation between the graded scan findings including shrinkage of the liver, splenic uptake or splenomegaly and severity of variceal changes of the esophagus. Exceptionally, however, apparently paradoxical correlation was noted between the severity of mottlings and varices. Thus, in the majority (73.5%) of patients mottlings were either absent or mild. This interesting observation is in favor of the view held by Christie et al. who consider the mottlings to be not faithful expression of actual scarring of the cirrhotic liver. This also would indicate that variceal changes are to be the results of intrahepatic arteriovenous shunting of blood with hypervolemic load to the portal system rather than simple hypertension secondary to fibrosis and shrinkage.

  • Colloid uptake in various hepatic conditions such as focal nodular hyperplasia, regenerating nodules in the cirrhotic liver, hamartoma, hemangioma and rarely hepatoma has been documented. Extrahepatic tumors may show colloid uptake and they include splenic hemangioma, malignant fibrous histiocytoma, breast carcinoma and Kaposi's sarcoma. The mechanism of colloid uptake in those lesions is associated with phagocytic activity in or around the tumors. We report a pancreas islet cell tumor that showed colloid uptake on $^{99m}Tc$-phytate liver scan without histologic evidence of phagocytosis by tumor cells or infiltration of phagocytes in the tumor Microscopically the tumor was highly vascular and showed diffuse hemorrhage throughtout the tumor. We postulated that extravasation of the colloid into the tumor insterstitium caused nonspecific colloid uptake in this tumor. It is expected that hemorrhagic tumor may show nonspecific colloid uptake without phagocytosis in or about the lesion.

  • Lipocortin 1 has been proposed as a putative mediator of anti-inflammatory actions of glucocorticoids. We investigated the role of lipocortin 1 in the effect of dexamethasone using rat splenic leukocytes. Concanavalin A(ConA; 1 ${\mu}g/ml$) increased the leukocyte proliferation and nitric oxide(NO) generation, which were measured as $[^3H]-thymidine$ uptake by the cells and nitrite accumulation in the culture media, respectively. Dexamethasone suppressed ConA-induced cell proliferation, in a concentration-dependent manner with $EC_{50}$ around 50nM. The addition of anti-lipocortin l(Anti-LCl) reversed dexamethasone effects: 0.24, 1.2, 6 ${\mu}g/ml$ of Anti-LC1 reversed dexamethasone(50 nM)-induced suppression of thymidine uptake by $9{\pm}3%$, $16{\pm}3%$, $36{\pm}5%$, respectively; 0.24, 1.2, and 6 ${\mu}g/ml$ of Anti-LCI reversed dexa-methasone-induced decrease of nitrite concentration by $49{\pm}16%$, $61{\pm}20%$, $77{\pm}19%$, respectively. The present data indicate that lipocortin 1 mediates, at least in part, glucocorticoids-induced suppression of leukocyte proliferation and blockade of NO generation.

  • Sixty-nine patients with diffuse lung uptake of $^{99m}Tc-tin$ colloid were evaluated to determine the kinds of associated diseases, the incidence of associated liver scan abnormalities, and prognosis. The results were as follows: 1) Diseases associated with diffuse lung uptake included malignancies in 31 patients, infectious diseases in 19, chronic liver diseases in 14, and others in 5. It appeared that the marked degree of lung uptake was associated with severe diseases. 2) Thirty-one of the 69 patients(45%) had abnormal liver size, 43(62%) had space occupying lesions or nonhomogeneity in liver image, 37(54%) had splenomegaly and 45(65%) had increased splenic uptake. Increased bone marrow uptake was found in 48(70%) and renal uptake in 15(22%). As the degree of lung uptake increased, there was a statistically significant (p<0.05) tendency for the incidences of the abnormal liver image and renal uptake to increase. 3) Sixty-two of the 69 patients were followed up for one to 439 days(mean 44 days) after liver scanning. Eleven(18%) were dead, 10(16%) were aggravated, and 13(21%) were improved. Most of improved patients had infectious diseases. It appeared that diffuse lung uptake of $^{99m}Tc-Tn$ colloid was found in the various diseases including malignancies, infections, and chronic liver diseases, and that it was strongly associated with other liver scan abnormalities, but was not necessarily associated with a poor prognosis, particularly when underlying diseases were infections.

  • The KGBT has been used to weak children with anorexia, fatigue, and growth retardation. This study was carried out to prove the effects of the hematopoiesis and the immune proliferation by KGBT. Previously, C57BL/6 mice was treated with cyclophosphamide(100mg/kg) for leukopenia, and then administered KGBT (concentration is 1.37 g/kg, 504 mg/kg, and 137 mg/kg) to the treated mice. The mice was analyzed expression of thrombopoietin(TPO), stem cell factor(SCF) and interleukin-3 from bone marrow cell, interleukin-10 (IL-10), and interferon-$ {\gamma}$(INF-${\gamma}$) from splenic cell, and NOSⅡ gene from macrophage using by RT-PCR. Also proliferation of immune cell was analyzed using 3H-thymidine uptake and flow cytometery in splenic cells. The results were obtained as follows ; 1. The total number of WBC, RBC and PLT was increased in the KGBT treated group than in the control group. 2. In vitro, the proliferation of splenic cells was increased in normal, control, and KGBT treated group. And Administration of KGBT was reduced the cytotoxicity by CTX. 3. In bone marrow cell, the gene expression of immune regulatory factor that associated with hematopoiesis, such as TPO, SCF, and IL-13 was increased in the KGBT treated group than control. 4 The titer of hemagglutinin and hemolysin was increased in the KGBT treated group than control. 5. In analysis of positive leucocytes from splenic cell of BALB/c mice, the subpopulation percent of CD4+, CD8+,and CD19+ was increased in the KGBT treated group than control.
