OBJECTIVE To examine the effects of estrogen therapy on cognition, mood, and cerebral blood flow in patients with AD. BACKGROUND Some studies have suggested estrogen may be effective in the treatment of AD. However, most of these studies were not controlled adequately. METHODS Fifty female AD patients were recruited in a randomized, double-blind,(More)
Ischemia is thought to be a major component in the pathogenesis of foot problems. The authors use the Xe-133 washout method to evaluate the blood perfusion of muscle tissue in the lower legs of patients with noninsulin-dependent diabetes mellitus (NIDDM). Eighty-five male patients with NIDDM ranging in age from 51 years to 79 years (mean, 66.5 years) and 47(More)
Pulmonary scintigraphy, including Xe-133 ventilation combined with Tc-99m MAA perfusion scans, was performed in 23 children (3 girls, 20 boys, ages: 2-9 years) with pectus excavatum, and the indices from lateral chest radiography were used for comparison. The findings of pulmonary scintigraphy were analyzed as 1) ventilation fractions (VF), and 2) perfusion(More)
Myocardial imaging with Tc-99m HMPAO WBC was used to detect myocarditis of Kawasaki disease in 103 infants and children (66 boys and 37 girls, mean age 3 years and 4 months). The clinical course of Kawasaki disease may be divided into three phases, from the onset of illness onset until all clinical symptoms and signs have disappeared. Twenty-four hour(More)
Eighteen patients with Kawasaki disease and suspected carditis (11 boys, 7 girls, mean age 18 months) in acute stages underwent Tc-99m HMPAO WBC imaging of the heart. Signs and symptoms subsided after conventional aspirin therapy and the intravenous injection of high-dose (400 mg/kg per day for 5 days) gamma-globulin treatments. Tc-99m HMPAO WBC imaging of(More)
Eimeria tenella microneme protein 1 (EtMIC-1) is highly conserved with TgMIC-2, which is involved in parasite binding specifically to host cells. Little is known about the immune responses and protective efficacy against E. tenella infection with EtMIC-1 antigen. In the present study, the recombinant proteins of E. tenella mature MIC-1 and adhesive domain(More)
Ten normal volunteers and 14 patients with hyperthyroidism had pinhole thyroid imaging 30 min after an intravenous injection of 10 mCi 99mTc-MIBI. Technetium-99m-MIBI thyroid uptake was calculated by the formula: [total counts with a region of interest (ROI) over the whole thyroid gland] divided by [(mean counts of every pixel in the neck soft tissue) x(More)
Fifteen cases (9 males, 6 females, ages: 18-73 y/o) of salmonella bacteremia were referred for a Gallium-67 citrate (Ga-67) scan to detect the focal site(s) of salmonella infection. Among them, 8 were finally proved to have focal infection(s). Their underlying diseases were systemic lupus erythematous (SLE, 4 cases), malignancies (2 cases), immunocompromise(More)
99Tcm-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) of the head and neck was performed in 20 patients with nasopharyngeal carcinoma (NPC) to detect the malignancies. Ten volunteers also underwent 99Tcm-MIBI SPECT of the head and neck for comparison. The results showed no MIBI uptake in the nasopharynx of any of the 10(More)
