location of focal infectious roc’2 As opposed to galhum, accumulation in normal bowel does not signfficantly affect imaging ofthe abdomen and pelvis. It can also identify extra-abdominal sites ofinfection as well; in one study, three patients had pneumonitis detected prior to the appearance of an abnormal chest roentgenogram 13 The “In-WBC scanning is performed by obtaining a leukocyte-rich fra...

In order to examine the subcellular distribution of 111In in “In-oxine-labeled human and rabbit platelets. we employed a hypothetical grain technique of EM autoradiograph analysis. The results indicated that in the rabbit ‘11In was concentrated within the platelet dense bodies. particularly when the platelets had been labeled in a plasma-free system. Under comparable conditions of labeling. hum...

-The sorption of 8-hydroxyquinoline onto some clays and oxides was studied as a function of concentration, pH, and time. The sorption reaction reached equilibrium in about 5 hr, was irreversible, and reached a maximum at pH 5. The decrease in sorption on both sides of the maximum was attributed to electrostatic interactions of charged molecules with similarly charged surfaces and/or neighbors a...

We separated platelets from whole blood and incorporated them into In-Ill and Te-99m agents. Sn-GHA, Tropolone, Oxine (sulphate) and HMPAO were used to diffuse radionuclides into the platelets. The effects of time, temperature, PH of incubation media; volume and concentration of ionophore; and volume and activity of ln-l 13m C13 and Te-99m on labeling efficiency were studied.

Untreated patients with Hodgkin's disease (HD) have a blood T-lymphocytopenia mainly caused by a reduction of the CD4+ subset. Indirect support for a sequestration of T cells in the spleen and tumor-involved lymphoid tissue has accumulated. To test the hypothesis that the blood CD4 T-lymphocytopenia in patients with HD is caused by an altered lymphocyte traffic, 12 untreated HD patients and fiv...

Novel mixed ligand bivalent copper complexes [Cu. L. A. ClO 4 ] and [Cu. L. A] where "L" is Schiff bases, namely 2-((3,4-dimethylisoxazol-5-ylimino)methyl)-4-bromophenol (DMIIMBP)/2-((3,4-dimethylisoxazol-5-ylimino)methyl)-4-chlorophenol (DMIIMCP), and "A" is heterocyclic compound, such as 1,10-phenanthroline (phen)/2,2(1)-bipyridyl (bipy)/8-hydroxyquinoline (oxine)/5-chloro-8-hydroxyquinoline ...
