[en] This volume contains the abstracts of the 5th International Symposion on Radiolabelling of Cellular Blood Elements to be held in Vienna, Austria, September 10-14, 1989. The Meeting is the fifth in a series of meetings designed to discuss the basics and clinical application of radiolabelling techniques. In these days, beside the search for new labelling agents and extending the knowledge in clinical use, the use of monoclonal antibodies is a big new challenge. All reviewed contributions that have been accepted for presentation are contained in this volume. (authors) 58 of them are of INIS scope

[en] It is aimed that through machine recognition, a significant quantitative description of the white blood cells be obtained. This technique will give the characterization of the normal and abnormal white blood cells which may eventually lead to exact and efficient blood examinations and to the possibility of using white blood cells as an effective biological monitor in the assessment of radiation damage and other pathological disorders. Described are the preparation of blood stains and staining procedure with Giemsa and Wright stains, photomicrography of white blood cells with the use of Kodak Dektol Developer and Kodak Acid-Bath Fixer. The film rolls were then scanned. The scanner is used to scan photographic transparencies of white blood cells. This instrument gathers information and converts cell features such as size, shape, ash and granulation into a series of parameters whose values are descriptive of the minute but essential structural characteristics of the cells. From July 1 -December 31, 1975, a total of 51 blood smears were collected and stained. From these blood samples, a total of 103 neutrophils, 30 lymphocytes and 12 monocytes were added to the film library

[en] Tc-99m labeled red blood cell (RBC) scintigraphy is commonly used in the evaluation of acute gastrointestinal (GI) bleeding. On Tc-99m RBC studies, GI bleeding is seen as an initial focus of increased radiotracer activity that on subsequent images increases in intensity and changes position in a pattern that confirms to segments of bowel. We report a case of a patient with multiple episodes of GI bleeding referred to detect the source of bleeding. A Tc-99m labeled RBC scan was performed and the findings showed a focal abnormal hot spot in the mid quadrant of the abdomen, seen promptly in initial dynamic images. Subsequent static and single-photon emission computed tomography-CT (SPECT-CT) images found it to be umbilical varices. Most varices fill promptly as in this case and should not be misinterpreted as a focus of hemorrhage. SPECT-CT should be used in such cases so that that false-positive interpretation can be avoided.

[en] This 2nd edition focuses on nuclear imaging characteristics and their complimentary nature to the radiograph. The latest equipment used in nuclear medicine is discussed throughout. This book depicts major body systems, and describes principles behind successful creation of an image of a particular organ. The chapter on lungs now includes material on venography, and a new chapter covering White Blood Cells has been added

[en] Antegrade placement of ureteral stents has successfully achieved in 41 of 46 ureters. When it was difficult to advance ureteral stents through the lesion, it was facilitated by retrograde guide-wire snare technique through urethra. Complications associated with the procedure were non-function of ureteral stent by occlusion, upward migration,and spontaneous fracture of ureteral stent. These complications were managed by percutaneous nephrostomy and removal of ureteral stents by guide-wire snare technique and insertion of a new ureteral stent. While blood cell in urine was markedly increased in about 50% of patients following the procedure

[en] Objective: To evaluate the clinical application of partial splenic embolization in the treatment o hypersplenism caused by schistosomiasis. Methods: Twenty four patients with hypersplenism caused by schistosomiasis were treated with peripheral partly splenic embolization with gelf.oam. The counts of' white blood cell (WBC) and platelet (PLT) were compared between pre-and post-splenic embolization. Results: The extent of splenic embolization were 50%-75%(mean 59.24%) with post-therapeutic follow-up of 6 months 2 years, showing significant increase of WBC count with preoperative, peak and the latest follow-up counts as (2.15±0.67) x 10⁹/L, (12.36±3.24) x 10⁹/L and (5.65±1.38) x 10⁹/L respectively (t=11.08, P< 0.001, pre-and post- therapeutically). PLT counts includ the preoperative, peak and the latest follow-up counts as (31.39±13.81) x 10⁹/L, (178.26±123.07) x 10⁹/L and (116.28±31.52) x 10⁹/L respectively (t=8.38, P<0.001, pre-and post-therapeutically). No severe complication occurred. Conclusions: Partial splenic embolizationg is safe, effective and micro-invading in the treatment of hypersplenism caused by schistosomiasis. It's long term efficacy needs to have further follow up. (authors)
