A variety of methods exist for counting sperm. Since the introduction of semen analysis, one of these methods, the hemocytometer, has been regarded as the gold standard by andrology laboratories and the World Health Organization (WHO, 1999). The flexible features of this approach, involving fixation and immobilization of sperm, dilution of highly concentrated samples, and the counting of sperm ...

OBJECTIVE This study aimed to evaluate the potential in vitro anti-leishmanial activities of moxifloxacin, linezolid and caspofungin against Leishmania tropica. METHODS In vitro effects of all agents were studied by using the microdilution method. For this purpose, serial dilutions of the aforementioned agents were prepared in concentrations between 4096 μg/mL-0.008 μg/mL. Afterwards, promast...

A viable cell count is essential to evaluate the kinetics of cell growth. Since the hemocytometer was first used for counting blood cells, several variants of the methodology have been developed towards reducing the time of analysis and improving accuracy through automation of both sample preparation and counting. The successful implementation of automated techniques relies in the adjustment of...

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 urina...

BACKGROUND Sensitive and accurate counting methods are required to assess the residual white cells (WBCs) in WBC-reduced blood components. The Nageotte hemocytometer, widely used for this purpose, is cumbersome, and its efficacy is dependent upon the skill of the operator. The performance of a simple fluorochromatic assay using tissue-typing microdroplet trays is presented here. STUDY DESIGN ...

Insect hemocytes have been the focus of researchers for decades (e.g., Jones, 1962; Ravindranath, 1978; Hall, 1983; Ribeiro & Brehelin, 2006). Most research has sought to increase our understanding of what factors influence hemocytes numbers, especially in response to various stressors (e.g., Silva et al., 2002; Andrade et al., 2003; Mochiah et al., 2003). Moreover, the recent increase in quest...
