The importance of measuring accurately and precisely the concentration of spermatozoa in semen is increasing as artificial insemination becomes widely practiced in veterinary medicine. This study tested the precision of the Neubauer hemocytometer with canine spermatozoa of varying concentrations within and between operators of different experience levels (Figure 1). We calculated the standard d...
A limiting factor in the biochemical quantitation of DNA and other nuclear constituents has been the inaccuracy of the enumeration of nuclei. The hemocytometer method has been accepted as a primary standard for counting nuclei and permits the use of morphologic detail as a means of control [S, 10, 17, 18, 21, 221. However, predictable errors in the hemocytometer method resulting from the Poisso...
The hemocytometer leukocyte adherence inhibition technique was employed in a criss-cross experimental design with two cancer patients (melanoma and colon carcinoma) and the corresponding tumor extracts. These extracts had been repeatedly tested for specific reactivity and lyophilized before transport to the workshop. The patients' leukocytes were mixed singly with each extract in the presence o...
OBJECTIVE To assess the usefulness of laboratory parameters, including peripheral white blood cell (WBC) count, C-reactive protein (CRP) concentration, erythrocyte sedimentation rate (ESR), and microscopic urinalysis (UA), for identifying febrile infants younger than 8 weeks of age at risk for urinary tract infection (UTI), and comparison of standard UA and hemocytometer WBC counts for predicti...
background and objective: this study was undertaken to assess the ability of standard urinalysis (ua) and hemocytometer white blood cell (wbc) counts for the diagnosis of urinary tract infection (uti) in patients with urinary symptoms. materials and methods: a total of 600 patients with symptoms of urinary tract infection were enrolled in this prospective study. standard ua, hemocytometer wbc c...
