Silver is commonly used in wound dressings and topical formulations to assist in the management of wounds that are infected or at risk of becoming infected. They provide potent broad-spectrum antimicrobial activity, but should not cause sustained staining of the skin, dermal or systemic accumulation of silver, or discomfort to the patient. However, clinicians and healthcare personnel have bee...
An improved silver carbonate impregnation method for marine ciliates is described. Compared to conventional methods, the new method of fixing and staining is easy to learn and yields easily reproducible results. Structures that are impregnated with silver carbonate such as nuclear apparatus, infraciliature as well as cortical and cytoplasmic microtubules and even contractile vacuole pore are st...
Telomerase activity has been observed in a high proportion of specimens from a wide variety of human malignant tumours, but not in non-neoplastic tissues. Measurement of telomerase activity is a possible diagnostic maker for malignant tumours. A non-isotopic telomeric repeat amplification protocol (TRAP) silver staining method for the detection of telomerase activity in human bone tumour tissue...
Acridine orange is a metachromatic intercalator used extensively in histochemistry to differentiate double- from single-stranded (ds, ss) nucleic acid by the emission of green and red fluorescence, respectively, under ultraviolet light. In the present study we standardised a protocol in order to use acridine orange to detect rotavirus ds RNA in polyacrylamide gels and compared it to silver and ...
We investigated the applicability of the pre-embedding immunoperoxidase technique to WGAapoHRP-Au retrograde tracing. After injection of the tracer into the substantia nigra of rat, the brain was fixed and cryostat sections were immunostained for dopamine. The sections were osmicated and silver-stained to amplify the colloidal gold particles. Products of both the immunoperoxidase staining and t...
BACKGROUND AND AIMS Several diagnostic methods are being employed to detect benign and malignant lesions, one of which is silver nitrate staining for organizer regions. The number of nucleolar organizing regions (NORs) can be used to show the degree of cell activity or metabolism in pathologic lesions. This study was designed to evaluate NORs as determi-nants of precancerous and squamous cell c...
