The leukocytosis-promoting factor (LPF), purified from materials extracted from agar in which Bordetella pertussis was grown, caused leukocytosis and an increased sensitivity to histamine when as little as 0.04 Ag of protein was given intravenously to mice. LPF was adsorbed onto erythrocytes, causing hemagglutination. As little as 0.03 ,g of LPF protein agglutinated chicken erythrocytes in 0.05...

INTRODUCTION Lung cancer is the leading cause of death among the cancers seen in the United States. Hypercalcemia and leukocytosis are two common paraneoplastic syndromes associated with lung cancer. Unfortunately patients presenting with Hypercalcemia- leukocytosis syndrome has a worse prognosis than patients presenting with lung cancer alone. CASE PRESENTATION We present a 67 yr old Caucasi...

A lipid fraction was obtained by extraction with chloroform-methanol (1:1 .v/v) of "the S-precipitate"prepared from whole human saliva by one precipitation.This fraction produced leukocytosis, but not hypocalcemia , in rabbits upon intravenous injection. Saliva-parotin-A purified from the S-precipitate possessed both hypocalcemic and leukocytosis-promoting activities, which remained unaffected ...

The leukocytosis- and lymphocytosis-promoting factor (LPF) of Bordetella pertussis has been isolated to near homogeneity by physical, chemical, and electron microscopical criteria. LPF contains 14.5% nitrogen and is lipid and carbohydrate free. It is apparently composed of four polypeptide subunits. LPF caused leukocytosis and lymphocytosis in "nude" as well as in normal mice. In addition, puri...

The leukocytosis-promoting factor (LPF), purified from materials extracted from agar in which Bordetella pertussis was grown, caused leukocytosis and an increased sensitivity to histamine when as little as 0.04 mug of protein was given intravenously to mice. LPF was adsorbed onto erythrocytes, causing hemagglutination. As little as 0.03 mug of LPF protein agglutinated chicken erythrocytes in 0....

We analyzed specimens from 268 patients with small lymphocytic lymphoma (SL) to identify prognostic factors significant for survival. These patients were staged and treated according to the protocols of the Cancer and Leukemia Group B, Eastern Cooperative Oncology Group, Southeastern Cancer Study Group, and the Southwest Oncology Group. Univariate analysis showed that a large-cell grade greater...

Leukocytosis refers to an increase in leukocyte count above the normal range in the blood and is a common laboratory finding in patients. In many cases, the mechanisms underlying leukocytosis are not known. In this study, we examined the effects, the structural determinants, and the underlying mechanisms of heparin-induced leukocytosis, a side effect occurring in 0.44% of patients receiving hep...
