Cresyl violet stained partial brain section of a Macaque. It is used in biology and medicine as a histological stain. Cresyl violet is an effective and reliable stain used for light microscopy sections. Initially, tissue sections are "defatted" by passing through graded dilutions of ethanol. Then, rehydrated by passing back through decreasing ...
Bielschowsky silver stain showing the processes of basket cells in the cerebellum.. The Bielschowsky technique is a silver impregnatiom method used in histochemistry for the visualization of nerve fibers, [1] including multipolar interneurons in the cerebellum.
Photomicrograph of Nissl bodies (two are indicated by arrows) in the cytoplasm of motor neurons in the anterior horn of the spinal cord; cresyl violet stain (purple) along with a luxol fast blue stain for myelin. Scale bar = 30 microns (0.03mm). Drawing of a motor neuron from the ventral horn of the medulla spinals of a rabbit.
This is done by using various basic dyes (e.g. aniline, thionine, or cresyl violet) to stain the negatively charged RNA blue, and is used to highlight important structural features of neurons. The Nissl substance ( rough endoplasmic reticulum ) appears dark blue due to the staining of ribosomal RNA, giving the cytoplasm a mottled appearance.
Masson's trichrome stain of rat airway.Connective tissue is stained blue, nuclei are stained dark red/purple, and cytoplasm is stained red/pink. Mouse skin stained with Masson's trichrome stain.
The most common supravital stain is performed on reticulocytes using new methylene blue or brilliant cresyl blue, which makes it possible to see the reticulofilamentous pattern of ribosomes characteristically precipitated in these live immature red blood cells by the supravital stains.
Crystal violet or gentian violet, also known as methyl violet 10B or hexamethyl pararosaniline chloride, is a triarylmethane dye used as a histological stain and in Gram's method of classifying bacteria. Crystal violet has antibacterial, antifungal, and anthelmintic properties and was formerly important as a topical antiseptic.
An analgesic adjuvant is a medication that is typically used for indications other than pain control but provides control of pain in some painful diseases. This is often part of multimodal analgesia, where one of the intentions is to minimize the need for opioids. [1] [2] [3]
