Effect of tocopheryl phosphate on key biomarkers of inflammation: Implication in the reduction of atherosclerosis progression in a hypercholesterolaemic rabbit model.

1. Many studies have evaluated the effectiveness of alpha-tocopherol (vitamin E) in the development and progression of cardiovascular diseases, with conflicting results reported on the protective effect of this anti-oxidant. 2.

Total body potassium and serum potassium among eating disorder patients.

Objective: The purpose of the study was to determine body composition, including total body potassium (TBK+), serum potassium, and lean body mass (LBM), in anorexia nervosa.

Method: TBK+ measurements, serum potassium levels, and anthropometric measurements were obtained from four anorectic patients in the first week after their hospital admission. All four patients had normal serum potassium levels but three of the four had significant depletion of total body potassium.

Prostate cancer imaging with a new monoclonal antibody: a preliminary report.

Background: Optimal treatment of prostate cancer depends on accurate staging. Computed tomography (CT) and magnetic resonance imaging have severe limitations, and standard bone scanning can show only destructive osseous metastases. A radiolabeled antibody specific to prostatic adenocarcinoma could theoretically find evidence of soft-tissue metastases and lymph node involvement.

Immunoscintigraphy of prostatic cancer: preliminary results with 111In-labeled monoclonal antibody 7E11-C5.3 (CYT-356).

A phase 1 study was conducted with the investigational immunoscintigraphic agent, 111In-CYT-356, a radiolabeled, site-specific immunoconjugate of monoclonal antibody 7E11-C5.3, in 40 patients with prostatic carcinoma and known distant metastases. Each patient received a single intravenous infusion of CYT-356 (dose range, 0.

Experimental increase in brain HIPDM uptake by hypercapnia.

The 30-min brain uptake of [125I]HIPDM was measured in conscious rats--normocapnic (n = 8), hypercapnic (n = 12), and hyperoxic (n = 6). A mean 41.2% higher uptake was found in the brains of hypercapnic animals (p less than 0.

Red blood cell volume (RBCV) and blood volume (BV) in male albino (NZW) rabbits with 99mTc.

Estimation of red blood cell volume (RBCV) and blood volume (BV) in experimental animals is important for studies concerning pharmaceutical distribution. In this study RBCV was measured, using 99mTc, in 64 male albino New Zealand rabbits with a body weight (BW) of 3.12 +/- 0.

Subacute and chronic bone infections: diagnosis using In-111, Ga-67 and Tc-99m MDP bone scintigraphy, and radiography.

The usefulness of indium-111 white blood cell scintigraphy in the diagnosis of subacute or chronic bone infection was examined in 21 orthopedic patients. In-111 WBC imaging was compared with gallium-67 and technetium-99m methylene diphosphonate skeletal scintigraphy and bone radiography, all studies being performed within 1 week. In-111 WBC scintigraphy showed no definite advantage over Ga-67 scintigraphy in the identification of chronic bone infection.

Evaluation of an immunoradiometric assay specific for the CK-MB isoenzyme for detection of acute myocardial infarction.

Clinical evaluation of patient's symptoms, electrocardiographic changes and increased serum enzyme levels, specifically creatine kinase (CK)-MB by electrophoresis, are established as the primary diagnostic indicators for myocardial infarction (MI). Two hundred fifteen patients were evaluated in this study. Of these patients, 102 were admitted to the coronary care unit and 113 were admitted to the emergency room and screened for possible MI.

Diagnosing myocardial infarction with a radioimmunoassay for the B-monomer of the creatine phosphokinase isoenzymes.

A diagnosis of myocardial infarction (MI) is usually established by the evaluation of clinical symptoms, electrocardiographic changes, and serum enzyme levels, specifically creatine phosphokinase, subunit MB (CK-MB), by electrophoresis. A total of 215 patients were evaluated in this study. One hundred two of them were admitted to the coronary care unit and 113 to the emergency room, where they were screened for possible MIs.

Comparisons of scintigraphy with In-111 leukocytes and Ga-67 in the diagnosis of occult sepsis.

In a prospective study involving 32 patients with clinical suspicion of focal infection, the sensitivity and specificity of In-111-labeled leukocyte (In-WBC) scintigraphy were compared with those of Ga-67 scintigraphy performed 24-48 hr later. Of a total of 192 body sites studied, 26 foci of infection were diagnosed by aspiration, cultures, or chest radiographs. Indium-WBC indicated 19 (73%) true-positive (TP) and four (2.

Qualitative detection of a human placental lactogen--binding substance by radioassay.

Serum levels of human placental lactogen (hPL) were measured by radioimmunoassay, and a method was developed for the detection of an hPL-binding substance by radioassay. Three groups of women were investigated: (1) normal adult women who had never been pregnant; (2) women with normal pregnancies; (3) high-risk pregnant women (those demonstrating low levels of hPL). All women who had never been pregnant and most women who had normal hPL levels were found to be negative for the hPL-binding substance, whereas 80% of the women with hPL levels less than 4.

Initial levels of CEA and their rate of change in pancreatic carcinoma following surgery chemotherapy and radiation therapy.

CEA levels and their rate of change in 41 patients with pancreatic carcinoma following surgery, chemotherapy and radiation therapy were determined. Surgical resection, though not curative, was associated with a decrease in CEA level, with approximately half these levels returned to normal. No correlation with survival was noted.

Circulating carcinoembryonic antigen in pancreatic carcinoma.

Circulating CEA levels were determined in 102 patients wtih histologically proven pancreatic carcinoma and 26 patients with chronic pancreatitis. In the group with pancreatic carcinoma eleven patients had resectable tumors, the mean CEA in the nonjaundiced patients was 10 +/- 5 ng/ml while the mean value in jaundiced patients in this group was 27 +/- 40. Thirty-four patients with nonmetastatic locally unresectable disease had a mean serum CEA of 25 +/- 52 with a range of 1 to 250 ng/ml.
