• Fischer 0., Dagmar Zendulkova: Staining With an Acridine Orange Derivative for the Detection of Mycoplasmas in Cell Cultures. Acta vet. Brno, 62,1993: 49-53. 24 cell cultures were examined for the presence of mycoplasmas by fluorescence methods using 3-amino-6-methoxy-9-(2-hydroxyethylamino) acridine (AMHA) or bisbenzimide 33258 (Hoechst), and by culture in liquid media containing glucose or ...

OBJECTIVE The aim of this study was to determine whether Acridine Orange (AO) can be used as a routine procedure in a physician's office to detect sperm deoxyribonucleic acid (DNA) fragmentation in patients with varicoceles. MATERIAL AND METHODS Forty-five patients with a mean age of 30.4 years, who had been diagnosed with varicoceles by physical examination and 30 healthy males with a mean a...

Of 7,871 blood cultures from hospital patients, 22 yielded growth of Streptococcus pneumoniae or Haemophilus influenzae type b. The identities of 19 (86%) of these 22 strains could be verified after 18 to 24 h of incubation by application of the Directigen meningitis test kit to the unheated, uncentrifuged supernatant from the cultures; thus, the turnaround time for these cultures was halved. G...

The sensitivity of three methods for the rapid identification of Cryptococcus neoformans was compared. These were: direct microscopy of india ink preparations, acridine orange staining followed by fluorescence microscopy and detection of cryptococcal capsular polysaccharide antigen by latex agglutination. The overall limit of detection was 3.5 +/- 5.4 X 10(3) CFU/ml (mean +/- SD, n = 27). When ...

Objective: Anticancer activities of Schiff bases S1 and S2 against MG-63 human osteosarcoma cells were performed described using an in vitro evaluation employing cytotoxicity apoptosis assay. Methods: used MTT assay to examine the effect compound on cell viability (S1 S2). Cell morphologies IC50 values obtained. The acridine orange (AO)/ethidium bromide (EB) dual staining technique was determin...

Context: Dental Bleaching or tooth whitening represents a conservative cosmetic approach even for children and adolescents, whom treatment may be readily accomplished without permanent alteration to the enamel surface thus limiting need lifelong maintenance. Aims: The aim of this study was compare efficacy banana peel orange as teeth agents in deciduous dentition. Methods Material: Twenty extra...

background: regarding the strong differentiation and anti-leukemic activity of dendrostellera lessertii extract, an active agent with similar capabilities was isolated from the crude extract of the plant leaves. the aim of this study was to determine whether the anti-proliferative effect observed for this compound, is differentiation-dependent among the drug-treated cells, using u937 cells. met...

background: currently, relation between reactive oxygen species (ros) ros concentration and semen quality was indicated. saffron has traditionally been not only considered as a food additive but also as a medicinal herb, which has a good antioxidant properties. objective: the aim of this study was to evaluate the protection potency of saffron and vitamin e on sperm chromatin integrity. material...
