- cancer cytology
Cytology is the study of cells using a microscope. Cancer is a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.
Preview- It`s possible to observe, the weight of smaller units of the stick can be calculated from markings stamped on the surface of the polyethylene mold, or from a graph or conversion table which are supplied with the molded stick. The entire stick or its subunits are used in the preparation of small volumes of the carbowax PEG 1450 fixative now used in cancer cytology for fixing, protecting, mailing and conserving cytological smears, for example Papanicolaou smears in the study of cancer of the female cervix. Mold is a form of fungus. Some molds can cause disease in humans. PEG is a polymer made by joining molecules of ethylene oxide and water together in a repeating pattern. PEG can be a liquid or a waxy solid. In medicine, forms of PEG can be used in ointments, in drugs or substances to make them stay in the body longer, or in laxatives. Also called polyethylene glycol. Cervix is the lower, narrow end of the uterus that forms a canal between the uterus and vagina.
- It`s possible to deduce that, carbowax PEG 1450 is the essential ingredient needed in preparing the alcoholic fixative now commonly used in cancer cytology. A new method is described showing how carbowax PEG 1450 sticks of uniform weight and length can be manufactured in thin polyethylene molds.
- It`s apparent that, carbowax PEG 1450 added to any alcohol forms a unique fixative that is used extensively in the study of Cancer Cytology. In 1957 I described the original method for fixation and preservation of cytological smears using the solid carbowax PEG 1450 dissolved in alcohol (see addendum).
