Metoprolol and the Peripheral Platelet Count
Acta Haematologica, 2009An acute oral administration of 50 mg metoprolol (a selective β-1-receptor antagonist) to 18 healthy volunteers induced a significant increase in the peripheral platelet concentration lasting more than 4 h. It is suggested that this increment in the platelet count originates from the exchangeable splenic platelet pool. The mechanism by which metoprolol

Platelet and Leukocyte Counts in Pregnancy
Obstetrical & Gynecological Survey, 1980Platelets and leukocytes in venous blood were counted with automated methodology in 23 women studied longitudinally throughout pregnancy and at six weeks after delivery. The average platelet count declined monotonically in a manner consistent with the gestational increase in blood volume.

Platelet Function in Patients with High Platelet Counts
Annals of Internal Medicine, 1975Platelet function tests were done to ascertain whether they might have discriminatory significance in the differentiation of a myeloproliferative disorder from secondary thrombocytosis in a patient with an elevated platelet count. Amongst 14 subjects with polycythaemia vera and essential thrombocythaemia, significant abnormalities of platelet ...

Aids to Electronic Platelet Counting
American Journal of Clinical Pathology, 1970Although the widespread use of electronic particle counters has considerably improved platelet counting technics, problem areas remain. Solutions to these problems are suggested: separation of platelet-rich plasma from whole blood by augmentation of rouleaux followed by 2 min. of sedimentation; a modification of a microliter syringe which permits a 1:3,

The proficiency testing of platelet counting
Transfusion Medicine Reviews, 1995Ontario's laboratory professionals have shown that they are able to successfully operate a proficiency testing program by making use of volunteers. The program serves and assists the laboratory directors in their own quality assurance program. The two prime reasons for the success of LPTP are that it is not seen by the professions to be regulatory and ...

Platelet counts in premature infants
The Journal of Pediatrics, 1964Summary 1. Platelet counts in 26 premature infants in the first 5 days of life ranged from 31,000 to 197,000 per cubic millimeter. 2. Serial weekly counts in 13 smaller infants(under 1,700 gram at birth) showed a decrease to below 50,000 platelets per cubic millimeter by 10 to 20 days of age in most infants with evidence of hemorrhagic tendency ...
