Complications associated with the vascular access for hemodialysis represent one of the most important causes of morbidity among patients with renal replacement therapy. Early detection of arteriovenous fistula (AVF) dysfunction is of great interest. We present the case of a 70 year old woman who underwent 111In-oxine-labeled-platelet scintigraphy to evaluate thrombogenicity at 3 weeks and 3 mo...

Platelet dynamics in chronic liver disease have been studied using 111Indium-8-hydroxyquinolone (111In-oxine) as a platelet label. In 20 patients, mainly with alcoholic cirrhosis, the platelet mean life span was reduced in 12 and the splenic platelet pool increased, often markedly so, in 15. However, the platelet count was not significantly related to mean bile span, the splenic platelet pool, ...

There is considerable disagreement as to whether oxine or tropolone is the best labeling agent for indium leukocytes. We have previously looked at the sensitivity of oxine-labeled 111In leukocyte scans for occult infections and now present a similar group of patients imaged with tropolone-labeled 111In leukocytes. Thirty-four patients (38 studies) with possible occult infection were prospective...

1. A detailed laboratory method is described for the labelling of human platelets with [111In]indium oxine. The 45 min method is simple, requires on 26 ml of blood and is suitable for routine clinical use. 2. After the labelling and resuspension of the platelets in plasma, aggregation responses to both adenosine diphosphate and collagen were similar to those of normal platelet-rich plasma. Less...

INTRODUCTION Despite its desirable half-life and low energy Auger electrons that travel further than for other radionuclides, 67Ga has been neglected as a therapeutic radionuclide. Here, 67Ga is compared with Auger electron emitter 111In as a potential therapeutic radionuclide. METHODS Plasmid pBR322 studies allowed direct comparison between 67Ga and 111In (1MBq) in causing DNA damage, includ...

introduction: the field of stem cell biology and regenerative medicine is rapidly moving toward translation to clinical practice. stem cell therapy seems to be a new treatment option for some diseases. so, tracking the distribution of stem cells is crucial to their therapeutic use. based on this fact we labeled human mesenchymal stem cells (mscs) with 111in- oxine for the first time in our coun...

Indium-111 (111In) and technetium-99m (99Tcm) Stealth liposomes were compared with 111In- and 99Tcm-labelled white blood cells (WBC) in experimental infection in a rabbit model. Preformed polyethylene glycol-coated liposomes and separated WBC were radiolabelled with either 111In-oxine or 99Tcm-hexamethylpropyleneamine oxime (99TcM-HMPAO). After the intravenous administration of one of the four ...

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