Twenty one units of platelet-rich plasma(PRP) were prepared from healthy volunteer blood donors, and each unit of the PRP was divided into two aliquots by using transfer bags. Using SEPACELLTM leukocyte-removal filters, each one aliquot of the PRP was filtered immediately after preparation, and the other aliquot was filtered after a 48-hour storage at a room temperature with continuous agitation. Belbre and after filtration, platelet numbers and two platelet activation markers, CD62 and CD63, were measured using hematologic autoanalyzer and'flow cytometry, respectively. The results were as follows: 1. The platelet numbers in the PRP were reduced after filtration. 2. On the point of the preparation of PRP, the mean percentage of CD63-posititve platelets(s32.86+/- 11.3.5%) was highehr than that of CD62-positive platelets(14.63+/-11.22%). 3. When filtered immediately after preparation of PRP, the CD62-positive platelets were significantly reduced(13.23+/-10.43%), however, CD63-positive platelets were not significantly reduced(29.83+/-11.05%). 4. After 48-hour storage, both two activation markers were increased, and the markers were significantly higher in the PRPs stored after filtration than in those stored without filtration. In conclusion CD63 would be a more sensitive platelet activation marker than CD62, and the platelets expressing CD62 seemed to be removed more than those expressing CD63 during filtration.

Transmycardial laser revascularization has made its position as a sole therapy for patients with chronic angina nonamenable to maximal medical therapy, percutaneous transluminal coronary angioplasty, and coronary artery bypass grafting. We report three cases of transmyocardial laser revascularization as a sole therapy for patients with recurrent angina after CABG.

This is a report of the clinico-pathologic findings in six cases of histologically verified malignant meningiomas-three hemangiopericytic and three anaplastic types. They were three males and three females and two of them were reoperated for recurrence. The hemangiopericytic types had similar angiographic and macroscopic features and malignant characteristics such as increased mitoses. The anaplastic types lacked typical arrangement, but had a large number of mitoses, increased cellularity, focal necrosis, pleomorphism, anaplasia, and the adjacent normal parenchymal infiltration. However the metastasis was not yet proven in these cases.
