The hemacytometer leukocyte adherence inhibition (LAI) assay was investigated with respect to immunological relevance, specificity, and cellular mechanisms. Humans were immunized to keyhole limpet hemocyanin, and rats were immunized to dinitrophenyl-bovine gamma-globulin. LAI analysis disclosed classic patterns of immune response kinetics. The LAI response was dose dependent in vitro with no in...

PURPOSE Compliance with post-vasectomy semen analysis could be improved with the availability of a simple, rapid and accurate home test. SpermCheck Vasectomy, a highly sensitive lateral flow immunochromatographic diagnostic device, was designed to detect extreme oligospermia or azoospermia in men after vasectomy. We report the results of clinical and consumer testing of SpermCheck. MATERIALS ...

In this study, our objective was to determine the steady-state intrapulmonary concentrations and pharmacokinetic parameters of orally administered linezolid in healthy volunteers. Linezolid (600 mg every 12 h for a total of five doses) was administered orally to 25 healthy adult male subjects. Each subgroup contained five subjects, who underwent bronchoscopy and bronchoalveolar lavage (BAL) 4, ...

The objective of this study was to compare the steady-state plasma and intrapulmonary concentrations of orally administered pyrazinamide in normal volunteers and subjects with AIDS. Pyrazinamide was administered at 1 g once daily for 5 days to 40 adult volunteers (10 men with AIDS, 10 normal men, 10 women with AIDS, and 10 normal women). Subjects with AIDS and with more than four stools per day...

We previously reported that circulating hemoglobin (Hb) CC erythrocytes contain oxygenated HbC crystals with little or no HbF and that HbF inhibits in vitro crystallization of HbC. We now report that HbS accelerates in vitro crystallization of HbC. Crystals were formed in 1.8 mol/L potassium phosphate buffer, pH 7.4, at 30 degrees C and were counted in several time intervals with a hematocytome...

The objectives of the present work were 3-fold. First, a new method for estimating daily sperm production was validated. This method, in turn, was used to evaluate testis output as well as deferent duct throughput. Next, this analytical approach was evaluated in 2 experiments. The first experiment compared left and right reproductive tracts within roosters. The second experiment compared reprod...

IMPORTANCE Acanthamoeba keratitis is a debilitating eye disease that requires effective topical drug therapy. Currently, there is no standard in vitro test to evaluate anti-Acanthamoeba drugs. OBJECTIVE To develop a practical in vitro complete-kill assay to assess anti-Acanthamoeba drugs. DESIGN AND SETTING Isolates of Acanthamoeba strains (n = 15) evaluated in a clinical laboratory. An in ...

objective(s) air pouch is a well-established inflammatory model in which fluid extravasations; leukocyte migration, angiogenesis and other parameters involved in the inflammatory response can be measured. in this study, the influence of gender on inflammatory parameters has been examined in the air pouch model. materials and methods to induce air pouch, adult male and female wistar rats were an...

background: trichomoniasis is the most common nonviral sexually transmitted human disease that is caused by protozoan trichomonas vaginalis. metronidazole is the selective drug in trichomoniasis treatment. however, the reported cases show an increasing trend of drug resistance. this study aimed to evaluate the effect of mango and blueberry extracts on t. vaginalis. materials and methods: t. vag...
