The increasing incidence of non-Hodgkin's lymphoma (NHL), coupled with the lack of optimal treatment options, has prompted the development of novel treatments. Of these, radioimmunotherapy is one of the most promising. Two of the radiolabeled monoclonal antibody therapies being studied in the treatment of NHL are yttrium 90 (90Y) ibritumomab tiuxetan and iodine 131 (131I) tositumomab. The radio...
Significant increase in the salivary gland weight was observed after exposure to single therapeutic dose of 3.7 MBq of 131I in mice. Pre-supplementation of antioxidants, O. sanctum leaf extract, turmeric extract and vitamin E for 15 days before 131I exposure demonstrated significant reduction in the salivary gland weight. No major histopathological changes were observed in the salivary gland of...
Objective: To evaluate the contribution of 131I scintigraphy and ultrasonography to the prediction of malignancy in thyroid nodules with indeterminate cytology in euthyroid patients. Subjects and methods: The sample consisted of 102 patients with thyroid nodules, submitted to FNAC and presenting an indeterminate cytological diagnosis (follicular neoplasm). Results: Malignancy was observed in 19...
The behaviors of an anti-Ia antibody (7.2) and an antibody directed at a lymphocyte adhesion molecule (S.5) radiolabeled with 131I were studied in normal dogs. Antibody 7.2 localized to spleen and, to a lesser extent, to marrow and lymph nodes. Antibody S.5 rapidly localized to marrow and spleen, achieving tissue/blood ratios greater than 6:1 within three hours of injection that were maintained...
Membranes from rat liver were analysed under reducing conditions. The components of the soluble membranes responsible for the binding of acetylated low density lipoprotein (acetyl-LDL) and maleylated bovine serum albumin (Mal-BSA) were chromatographed on a polyethyleneimine-cellulose column and subsequently separated by gel electrophoresis. For both ligands a major binding protein (Mr = 35,000)...
Hellenic Journal of Nuclear Medicine January April 2011 www.nuclmed.gr 2 Figures 2 and 3. 131I-SPET study (Fig. 2) further clarified these foci in both kidneys. 18F-FDG-PET scan (Fig. 3) done on a separate day revealed abnormal foci of 18F-FDG uptake in the lower poles of both kidneys, corresponding to the foci seen on post treatment 131I-SPET. In the 18F-FDG-PET image, the foci can be well vis...
background: the therapeutic administration of 131i for thyroid remnant ablation and for metastases comes up with some adverse effects. this study was conducted to investigate whether single high dose radioiodine therapy affects lacrimal gland functions or not. materials and methods: seventy-eight eyes of 39 patients, who were diagnosed as differentiated thyroid carcinoma, were objectively teste...
OBJECTIVES In clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (DTC) patients with high serum thyroglobulin (Tg) and negative 131I whole-body scan (WBS) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. The purpose of this study was to evaluate the value of 18F-FDG PET/CT scan in DTC patients with high serum T...
Radioiodine therapy (RAI) has proven effective for the treatment of patients exhibiting differentiated thyroid cancer (DTC) with pulmonary metastases. However, the early detection of metastasis remains challenging, and various studies have reported variations in radioiodine treatment efficacy. The present study investigated whether RAI is an effective method for the treatment of DTC with pulmon...
The receptor occupancy required to produce cannabinoid effects in the central nervous system was determined in both a neurochemical and a behavioral assay for cannabinoid actions. In the neurochemical experiments, performed on superfused rat hippocampal slices, electrically evoked [3H]acetylcholine release was inhibited by the cannabinoid agonist, WIN 55212 to 2 with an EC50 of 0.005 microM and...
