BACKGROUND
The erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser has been widely used in the dental clinic; however, few studies have demonstrated the advantages of the use of this laser for bone osteotomies. The purpose of this study is to evaluate and compare the bone repair
This study attempts to characterize thallium-201 (201TI) uptake in patients with bone and soft-tissue sarcoma and to compare these findings with gallium-67 (67Ga) and bone scintigraphy with emphasis on evaluating tumor viability before and after chemotherapy. Thirty-eight patients with
The efficacy of gallium (Ga) nitrate was examined in a murine model of sepsis. Male Balb/c mice (6-8 weeks) were randomized into 3 groups: 1) vehicle-treated controls 2) mice with sepsis induced by treatment with 0.3 mg i.v. of Propionibacterium acnes followed one week later by 0.01 microg
Seventeen patients with histologically proven primary liver-cell carcinoma were evaluated by a technetium-99m sulfur colloid liver scan as well as with gallium-67 citrate. Twelve of the 17 patients (71%) showed gallium uptake in the tumor. Eleven of the 12 patients (92%) with a moderately or
Gallium nitrate (GN) was evaluated for its ability to interfere with a cute rejection of DBA/2-->C57BL/6 heterotopic cardiac allografts, in comparison with the depleting anti-CD4 mAb, GK1.5. The administration of GN for 30 days (s.c. 30 mg/kg elemental gallium on days 0 and 3, 10 mg/kg every third
Hypercalcemic nude mice bearing a canine adenocarcinoma (CAC-8) model of humoral hypercalcemia of malignancy (HHM) were treated daily with gallium nitrate (60 mg/kg of elemental gallium subcutaneously (SC) on day 0, followed by 20 mg/kg/day) for 5 days. Gallium nitrate significantly decreased (p <
Acute toxicity studies were conducted on copper gallium diselenide (CGS), copper indium diselenide (CIS), and cadmium telluride (CT), three novel compounds used in the photovoltaic and semiconductor industries. Female Sprague-Dawley rats (six rats/dose) were administered 0, 12, 25, 50, or 100 mg/kg
Gallium is antiproliferative to many types of cancer, due primarily to its ability to act as a non-functional mimic of ferric iron (Fe(3+)). Because Fe(3+) is needed for ribonucleotide reductase activity--and thus DNA synthesis--gallium can inhibit DNA production and cell division. Diagnostic
Exposure to gallium arsenide (GaAs) is a potential hazard in the semiconductor industry and there is a need for specific biological indicators of exposure/toxicity for this compound. These studies examined effects of GaAs exposure on the heme biosynthetic pathway enzyme delta-aminolevulinic acid
Massive bone marrow necrosis was rare, and most of these cases were accompanied with malignant disease. We report a case that was thought to be idiopathic massive bone marrow necrosis. It was a 58 y.o. male who was admitted because of blue toe syndrome and hypergammaglobulinemia. We tried to detect
OBJECTIVE
To report on the occurrence of necrotizing type of retinopathy resulting in rhegmatogenous retinal detachment in a patient with asymptomatic sarcoidosis.
METHODS
A 38-year-old healthy man presented with poor vision of 0.1 in his left eye of 3 days duration and was found to have panuveitis
A 44-year-old man was admitted with fever elevation and dyspnea. Chest X-ray and CT examination indicated a 6 x 4 cm anterior mediastinal tumor, pleural effusion and pericardial effusion. Blood examination showed no inflammation findings. Gallium scintigraphy indicated no uptake at the tumor. He
