They may occur in several different lung diseases [1] and may refer to parts of the desquamated epithelium seen in lavages from asthmatic patients. [2] These microscopic casts are named after German physician Heinrich Curschmann (1846-1910). They are often seen in association with creola bodies and Charcot-Leyden crystals. They are elongated ...
Whole lung lavage (WLL), also called lung washing, is a medical procedure in which the patient's lungs are washed with saline (salt water) by filling and draining repeatedly. It is used to treat pulmonary alveolar proteinosis , in which excess lung surfactant proteins prevent the patient from breathing.
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
Micrograph showing hemosiderin-laden alveolar macrophages, as seen in a pulmonary hemorrhage. H&E stain.. An alveolar macrophage, pulmonary macrophage, (or dust cell) is a type of macrophage, a professional phagocyte, found in the airways and at the level of the alveoli in the lungs, but separated from their walls.

Like all types of glass, it is a state of matter intermediate between the closely packed, highly ordered array of a crystal and the highly disordered array of liquid. [1] Volcanic glass may refer to the interstitial material, or matrix, in an aphanitic (fine-grained) volcanic rock, or to any of several types of vitreous igneous rocks.

A very rapid quench is essential to create martensite. For a eutectoid carbon steel of thin section, if the quench starting at 750 °C and ending at 450 °C takes place in 0.7 seconds (a rate of 430 °C/s) no pearlite will form, and the steel will be martensitic with small amounts of retained austenite.
