  • Lipiodol-anticancer suspensions containing fluorouracil, tegafur, mitomycin C, methotrexate, or adriamycin were prepared by Shinohara method using aluminum monostearate as a dispersing stabilizer. Lipiodol-suspension showed thixotropic property when the concentration of aluminum monostearate was above 2%. Observed thixotropic area which reflects the extent of thixotropic breakdown indicated that the thixotropic property of Lipiodol-suspensions maintained for six weeks in a refrigerator$(4^{\circ}C)$. Lipiodol-anticancer suspensions containing 2% aluminum monostearate maintained a more stable suspension system compared with simple mixtures and Lipiodol-anticancer suspensions without aluminum monostearate. As the concentration of aluminum monostearate increased, the drug release from Lipiodol-anticancer suspensions was more retarded.

  • Purpose: Surge in patients with hepatocellular carcinoma, hepatic artery chemical embolization is one of the effective interventional procedures. The PET/CT examination plays an important role in determining the presence of residual cancer cells and metastasis, and prognosis after embolization. The other hand, the hepatic artery chemical embolization of embolic material used lipiodol produced artifacts in the PET/CT examination, and these artifacts results in quantitative evaluation influence. This study, the radioactivity density and the percentage error was evaluated by the extent of the impact of lipiodol in the image of PET/CT. Materials and Methods: 1994 NEMA Phantom was acquired for 2 minutes and 30 seconds per bed after the Teflon, water and lipiodol filled, and these three inserts into the enough to mix the rest behind radioactive injection with $20{\pm}10MBq$. Phantom reconfigure with the iterative reconstruction method the number of iterations for two times by law, a subset of 20 errors. We set up region of interest at each area of the Teflon, water, lipiodol, insert artifact occurs between regions, and background and it was calculated and compared by the radioactivity density(kBq/ml) and the% Difference. Results: Radioactivity density of the each region of interest area with the teflon, water, lipiodol, insert artifact occurs between regions, background activity was $0.09{\pm}0.04$, $0.40{\pm}0.17$, $1.55{\pm}0.75$, $2.5{\pm}1.09$, $2.65{\pm}1.16 kBq/ml$ (P <0.05) and it was statistically significant results. Percentage error of lipiodol in each area was 118%, compared to the water compared with the background activity 52%, compared with a teflon was 180% of the difference. Conclusion: We found that the error due to under the influence of the attenuation correction when PET/CT scans after lipiodol injection performed, and the radioactivity density is higher than compared to other implants, lower than background. Applying the nonattenuation correction images, and after hepatic artery chemical embolization who underwent PET/CT imaging so that the test should be take the consideration to the extent of the impact of lipiodol be.

  • An iodized oil such as Ethiodol or Lipiodol was selectively retained in the tumor vessels of the large hepatomas as well as in the small daughter hepatomas for long periods following the intra-arterial hepatic injection of such contrast material. The specific aim of the study is to deliver a high internal radiation dose to hepatocellular carcinoma (HCC) in an attempt to control the disease. We were able to replace a small fraction of the stable iodine (I-127) of the 37% iodine in Lipiodol by the $I^{-131}$ with 100% exchange efficiency. $I^{-131}$ labeled Lipiodol was injected through the super-selected tumor feeding artery under superselection or into the proper hepatic arterial level of patients who have malignant hepatomas confirmed by aspiration cytology serum AFP and various imaging modalities. Clinical traial was performed on 43 cases during recent 6 months and follow-up observation was carried out. No severe complications or other adverse reactions were encountered until nowdays. $I^{-131}-Lipiodol$ was stable in vivo and no significant activity was noted in the thyroid, stomach, blood and urine after the injection. Only small fraction of radioisotope activity was noticed in the both side of lungs. Tumor to normal liver radio was very high. Therefore, $I^{-131}-Lipiodol$ (or P-32-Lipiodol) will be effective delivering high internal radiation dose to the tumor while delivering small radiation doses to normal tissues. Labeling, tumor dose calculation and preliminary findings will be presented.

  • The study was conducted to improve the efficiency of the test and to reduce the exposure dose of patients and operators by analyzing the difference in the moving speed of Lipiodol according to the temperature during lymphography. The device for injecting Lipiodol at a constant pressure was self-made, and after inserting Lipiodol into the Connecting Tube, the moving speed of the contrast agent was photographed at temperatures of 26℃, 36℃, and 46℃ using a heat transfer device. Lipiodol movement time from the Support Catheter to 20cm was measured and analyzed, and statistical significance was confirmed. In the 46℃ environment, the average moving time was 11 seconds, at 36℃ the average was 13 seconds, and at 26℃ the average was 17 seconds. Lipiodol showed a significant difference in moving time with increasing temperature (p<.001), and it was confirmed that the higher the temperature, the faster the moving speed. In the case of lymphangiography, when heated to a certain temperature (46 degrees) rather than injecting Lipiodol at room temperature, the injection speed can be increased and the speed of movement in the lymphatic vessel can be improved.

  • Transcatheter arterial chemoembolization(TACE) was performed in a 61 year old male patient with hepatocellular carcinoma with 10 cc of Lipiodol and 50 mg of doxorubicin. Three days later, he complained of dyspnea and dry cough. The arterial blood gas study revealed moderate hypoxemia and hypocarbia. The chest PA showed acute pulmonary edema with bilateral pleural effusion. To rule out the possibilities of acute respiratory failure caused by infection, pulmonary embolism or congestive heart failure, we performed several laboratory studies. The blood and sputum culture studies revealed negative results for bacterial growth. The echocardiogram was normal. The abdominal CT scan and MR imaging revealed no thrombus or mass lesion in the inferior vena cava. So we concluded pulmonary oil embolism induced by lipiodol as the cause of acute lung injury. Four weeks later, clinical symptoms and chest x-ray were markedly improved with conservative care. We report a case of acute lung injury after TACE with lipiodol and doxorubicin, with review of literatures.

  • Radiography is one of the important tool adopted in daily dental practice and medical diagnosis. To visualize soft tissuechange various contrast media has Been introduced. Any cavity or space can be easily determined by increasing the X-ray absorption of the cavity using the radiopaque contrast media which widely employed in medical radiography to show much of the digestive, cardiovascular, pulmonary, and renal system. The essential part of any radiopaque medium is a heavy element that can absoarb most of the X-ray beam. The element must be noninjurious and easily eliminated. Both aqueous and oil suspensions of iodine containing compounds' are available to the dental profession, for example Lipiodol and Dionosil. The study was designed to determine toxic effect of Lipiodol to the vital pulp and to confirm visualization ioprovement in pulp canal. 1. Thin mixture of Calcium hydroxide and Lipiodol was applied to 19 deep vital cavities for 24 hours. Only one case complained slight pain for short time. 2. Cotton pellet over-saturated in Lipiodol was inserted in coronal chamber of which 6 were non vital and 5 were vital. The transference of Lipiodol was not noticed in every case after 24 hours. 5 cases with vital pulp tissue in the canals showed no clinical symptome. 3. Extracted 20 teeth were routinely prepared for endodontic treatment and applied Lipiodol in conjunction with cotton fiber as deep as midportion of the roots. After 24, hours the medicament reached to nearly the end of apex, but there were no evidence of penetration in dentine layer and migrate into ramified canal.

  • Purpose: Lipiodol is used for targeting liver cancers by administrating through the hepatic artery. In the present study, feasibility of Re-188-sulfur colloid suspension in lipiodol as a liver cancer targeting agent was investigated. Materials and Methods: Re-188-sulfur colloid was prepared, harvested by centrifugation, washed with organic solvent and then suspended into lipiodol. Biodistribution of Re-188-sulfur colloid in normal saline and its suspension in lipiodol in mice after 1 hr of injection through the tail vein were investigated. Biodistribution and autoradiography of tumor-hearing liver was acquired after 5 min post-injection into left ventricle of the tumor-inoculated rats. Results: After 1 hr of injection with Re-188-sulfur colloid suspensiob in lipiodol through the tail vein in normal mice (n=3), the uptakes in the liver and lung were $5.2{\pm}0.7\;and\;91.0{\pm}1.7%$ ID/organ, respectively. After 5 min of injection with Re-188-sulfur colloid suspention in lipiodol through the left ventricle in the tumor-inoculated rats (n=4), uptakes in the normal liver, hepatoma, and lung were $0.41{\pm}0.28,\;1.88{\pm}1.57,\;and\;1.65{\pm}1.54%$ ID/organ, respectively. And autoradiography of hepatoma showed increased uptake than normal liver tissues. Conclusion: Re-188-sulfur colloid suspension in lipiodol injected through the artery shows higher uptake in the hepatoma than normal liver tissue that indicates the feasibility as a new radiopharmaceutical for therapy of hepatoma.

  • Transarterial chemoembolization (TACE) is a widely accepted nonsurgical modality used for the treatment of multinodular hepatocellular carcinoma (HCC). The careful selection of the candidate is important due to the risk of developing various side effects. Fever, nausea, abdominal pain, and liver enzyme elevation are commonly known side effects of TACE. Hepatic failure, ischemic cholecystitis, and cerebral embolism are also reported, although their incidence might be low. Pulmonary complication after TACE is rare, and the reported cases of lipiodol pneumonitis are even rarer. A 53-year-old man was treated with TACE for ruptured HCC associated with hepatitis B virus infection. On day 19 after the procedure, the patient complained of dyspnea and dry cough. Chest computed tomography showed diffuse ground glass opacities in the whole-lung fields, suggesting lipiodol-induced pneumonitis. After 2 weeks of conservative management, the clinical symptoms and radiologic abnormalities improved. Reported herein is the aforementioned case of lipiodol-induced pnemonitis after TACE, with literature review.
