The dissolution rates of indomethacin from low molecular weight (mol. wt) alginate dispersions were significantly enhanced in comparison with that of indomethacin alone. The dispersion with lower mol. wt alginate exhibited more rapid dissolution rate than that of dispersion with higher mol. wt alginate. These enhanced dissolution rates of indomethacin by(More)
The HBeAg was detected in 5 of 24 patients with acute type B hepatitis (20.8%), 33 of 95 with chronic hepatitis (34.7%), 6 of 33 with liver cirrhosis (18.2%), and 3 of 39 with hepatocellular carcinoma (7.7%). On the other hand, anti-HBe was found in 4.2% of acute hepatitis, 18.9% of chronic hepatitis, 9.1% of liver cirrhosis, and 12.8% of hepatocellular(More)
A 40-year-old female who had lung and liver metastases from malignant pheochromocytoma was treated with 3.7 GBq 131I-MIBG (metaiodobenzylguanidine). After the treatment, 131I-MIBG showed increased uptake in the metastatic lesions of the lung and liver. The size of tumor was no significant change on CT and MRI, but the intensity of liver metastases decreased(More)
Fluorescence polarization technique was applied for the assay of angiotensin I (Al) in human plasma. In this assay system, fluorescein labeled Al (F-Al), which retained the original antigenicity, and antibody to Al was allowed to interact in a cuvette in the instruments yielding an increase in the fluorescence polarization (P) value. Non-labeled Al in the(More)
