We conducted a randomized, double-blind, placebo-controlled trial to test the efficacy of the 14-valent pneumococcal capsular polysaccharide vaccine in 2295 high-risk patients (patients with one or more of the following: age above 55 years and the presence of chronic cardiac, pulmonary, renal, or hepatic disease, alcoholism, or diabetes mellitus).(More)

This study evaluates the effects of cytokines, used singly and in combination, on the microbicidal activity of human monocyte-derived macrophages (MDM) against intracellular Candida albicans in the presence and absence of fluconazole. In the absence of fluconazole, the addition of tumor necrosis factor alpha (TNF-alpha), interleukin-1beta (IL-1beta), gamma(More)
The maximum phagocytic and bactericidal capabilities of normal human PMNs against a seroresistant strain of Pseudomonas aeruginosa were evaluated by morphological observation, uptake of radiolabeled bacteria, and quantitative killing methods. The number of bacteria killed per PMN increased from 3 to 23 as the bacteria-to-PMN ratio was increased from 3:1 to(More)
An inhibitor of coagulation factor XIa was purified from serum-free conditioned medium of HepG2 liver cells. Platelets stimulated with thrombin or calcium ionophore (A23187) secrete a protein functionally and immunologically identical to the inhibitor, implying a role for this inhibitor in hemostasis. Analysis of the amino-terminal amino acid sequence and(More)
We reported previously that plasma levels, urinary excretion, and metabolic production of cyclic guanosine 3',5'-monophosphate (cGMP) are increased in gravid rats, and postulated that endogenous nitric oxide (NO), a potent vasodilator and immune modulator, may mediate this change. Four lines of evidence are now presented demonstrating increased biosynthesis(More)
Response to thermal stimulation and the analgesic effectiveness of morphine during various phases of the diurnal cycle were assessed by the hotplate method. Saline treated controls exhibited shortest reaction times during the last quarter of the light-phase and first quarter of the dark phase. Longest reaction times were recorded during the last quarter of(More)
