A new, formalin-inactivated vaccine for Venezuelan equine encephalitis (VEE) virus (C-84), prepared from an attenuated vaccine strain of virus (TC-83), was tested in humans. Only occasional, mild, local and systemic reactions were noted in 28 volunteers; no meaningful changes in clinical laboratory values occurred. The vaccine augmented preexisting titers(More)
An attenuated chikungunya (CHIK) virus clone was developed for production of a live vaccine for human use. CHIK strain 15561 was subjected to 18 plaque-to-plaque passages in MRC-5 cultures before CHIK 181/clone 25 was selected as vaccine seed based on homogeneous small plaque size, suckling mouse avirulence, reduced monkey viraemia and genetic stability.(More)
OBJECTIVES To evaluate the effect of oral potassium citrate therapy on urinary excretion rates of citrate. Tamm-Horsfall protein (THP), and on calcium oxalate monohydrate crystal agglomeration inhibition [tm], in patients with recurrent calcium stone formation. METHODS To evaluate the effect of oral therapy with potassium citrate on urinary citrate, THP,(More)
The relationships between age, systemic and renal hemodynamics, circulating catecholamines (norepinephrine, epinephrine and dopamine) and intravascular volumes were studied in 38 normotensive subjects and in 77 patients with borderline essential hypertension. Borderline hypertensive patients had a higher cardiac index (p less than 0.02) and renal blood flow(More)
PURPOSE Epidemiological data indicate a sharp increase in urinary calcium stone formation after menopause. We investigated the role of menopausal estrogen replacement therapy on the urinary constituents and characteristics that may influence recurrent calcium oxalate stone disease. MATERIALS AND METHODS Urinary constituents in 28 postmenopausal women on(More)
Formalin-inactivated Venezuelan equine encephalomyelitis vaccine was prepared from virus propagated in rolling-bottle cultures of chicken embryo cells. The attenuated, TC-83 strain of virus was propagated in these cultures with a maintenance medium consisting of serum-free medium 199 containing 0.25% human serum albumin and antibiotics. By adjustment of(More)
To evaluate the clinical utility of in vitro calcium oxalate monohydrate (COM) crystallization kinetics measurements and to determine the effect of quantitative removal of urinary Tamm-Horsfall glycoprotein on such measurements, we examined 24-hour, room temperature urine collections of patients from our Stone Clinic and of normal subjects from our research(More)
In rats, gonadal steroid hormones present during the neonatal period produce permanent or "organizational" effects that play a role in the sexual differentiation of the brain and sexually dimorphic patterns of behavior. Because there exists a sexually dimorphic pattern in the development of hypertension in the spontaneously hypertensive rat (SHR), we(More)
Polyriboinosinic.polyribocytidylic acid [poly(I).poly(C)] stabilized with poly-l-lysine and carboxymethylcellulose [poly(ICLC)] has been previously shown to be a compound with marked adjuvant activity when given in high doses with inactivated Venezuelan equine encephalomyelitis (VEE) virus vaccine. This study investigated the effects of much lower doses of(More)
OBJECTIVES The agglomeration of preformed crystals of calcium oxalate has been hypothesized to be the rate-limiting step in renal stone-forming activity (SFA). The effect of urine on the in vitro inhibition of agglomeration of seed crystals of calcium oxalate monohydrate, designated [tm], has been used to monitor SFA in calcium oxalate stone formers(More)
