E ARLIER OBSERVATIONS of elevated blood and urine histamine levels in myeloproliferative disorders1’2 have recently been confirmed and extended in this laboratory using a sensitive and specific spectrophotofluorometric assay.3 Whole blood and urine histamine content was demonstrated to be increased in uncontrolled polycythemia vera, “spent” polycythemia, and myelofibrosis with myeloid metaplasi...

BACKGROUND Inflammation has been demonstrated to be an important risk factor for the development of cardiovascular disease (CVD). The relationship of the peripheral leukocyte count to the severity of stable angina remains to be clarified. The present study analyzed the relationship of the peripheral leukocyte count to the severity of stable angina determined by coronary angiography. METHODS T...

Linezolid (LZD), severed as the first oxazolidinone antibiotic, was active against multidrug-resistant gram-positive strains. LZD can induce thrombocytopenia, anemia and leukocytopenia. Currently, reports on pure red cell aplasia (PRCA) cases induced by LZD are relatively rare [4-7]. In this paper, we reported a patient with PRCA twice induced by LZD. A 37-year-old man was diagnosed with myelody...

BACKGROUND Information-transducing heterotrimeric G proteins have been implicated previously in the mechanism of action of mood stabilizers and in the pathophysiology of mood disorders. Mononuclear leukocytes of patients with unipolar and bipolar depression have been characterized by reduced measures of the stimulatory and inhibitory G proteins. In this study, patients with seasonal affective d...

By B. J. KENNEDY T HE SUCCESSFUL TREATMENT of cancer and leukemia by agents which have hematosuppressive effects depends upon a selective toxicity, whereby the tumor cell is inhibited rather than the normal cell. Further information is needed on the life of the leukocyte, particularly the generative cycle and the normal or abnormal physiologic rhythms. The basic mechanism of the movement of leu...

Leukapheresis and plateletpheresis are rather commonly performed in order to obtain single donor concentrates of granulocytes and platelets. These procedures, although relatively safe, present occasional risks to donors and recipients. Some of the occasional adverse problems experienced by donors include citrate toxicity or acute hypocalcemia, hypotension, hypervolemia, venospasm or vein occlus...

OBJECTIVE The goal of this study was to investigate the role of platelets in systemic and cardiac inflammatory responses and the development of postinfarct ventricular complications, as well as the efficacy of antiplatelet interventions. METHODS AND RESULTS Using a mouse myocardial infarction (MI) model, we determined platelet accumulation and severity of inflammation within the infarcted myo...

OBJECTIVE The purpose of the presenting study was to determine how frequently external ventricular drainage (EVD) device should be changed in children with ventriculopertienal shunt (VPS) infection during prolonged intravenous antimicrobial therapy. METHODS In this retrospective study, 25 children with VPS infection were evaluated between January 2012 and December 2013. In these children VPS ...

The abscopal effect is an extremely rare phenomenon occurring when irradiation or treatment of a primary tumor burden not only results in debulking of the targeted site but also reduces tumor size at distant sites from the intended treatment area. We present the abscopal effect occurring in a patient with low-grade marginal zone lymphoma who subsequently received radioactive iodine therapy for ...
