Nuclear chromatin variations in human spermatozoa undergoing swim-up and cryopreservation evaluated by the flow cytometric sperm chromatin structure assay.
The sperm chromatin structure assay (SCSA) is a flow cytometric (FCM) technique which exploits the metachromatic properties of Acridine Orange to monitor the susceptibility of sperm chromatin DNA to in-situ acid denaturation. SCSA was used to study the chromatin structure variations of human spermatozoa in semen, both before and after swim-up and after cryopreservation. Semen samples were provi...
متن کاملAcridine orange staining for rapid diagnosis of Acanthamoeba keratitis.
Acanthamoeba keratitis is uncommon, but one of the most severe infectious diseases of the cornea. Delayed diagnosis or misdiagnosis as bacterial or herpes simplex keratitis leads to extensive corneal inflammation and profound visual loss. Therefore, accurate and rapid diagnosis of Acanthamoeba keratitis is essential for successful treatment and good prognosis. We evaluated the usefulness of acr...

with Acridine Orange By DAvID M. JOHNSON, PEYTON T. PIiArr AND PEnnY G. RuGBY I HE IMPORTANCE OF lymphocytic RNA in immune function has received widespread attention in recent years.’ A case in point is the work of Mannick and Egdahl showing that adoptive immunity can be transferred from one animal to another by means of lymphocytic RNA.2 The RNA of the lymphocyte can be evaluated and compared ...
متن کاملHistochemical observations on Mycoplasma after staining with acridine orange.
Mycoplasma colonies and Mycoplasma cells in preparations from infected milk and lymph nodes were observed for their fluorescent qualities after treatment with acridine orange. Mycoplasma colonies fluoresced brilliant red or red-orange. When treated after exposure to ribonuclease, the colonies fluoresced lime-green. There was no fluorescence when both ribonucleic acid and deoxyribonucleic acid w...
متن کاملGiemsa versus acridine orange staining in the fish micronucleus assay and validation for use in water quality monitoring.
This study concerns a comparative analysis of the acridine orange and Giemsa staining procedures for the fish erythrocyte micronucleus assay. The goal was to optimize the assay in the context of field water monitoring. Fish (Carassius carassius) were exposed to a reference genotoxic agent, cyclophosphamide monohydrate 5 mg l(-1) for 2, 4, and 6 days before testing. Slides from each individual w...
