Sputum liquid crystal
It is a sharp, colorless rhombus crystal at both ends, with strong refractive properties and different sizes. It often coexists with eosinophils and K. schman, and is easily found in eosinophils. Newly coughed sputum is often not found, and can appear in large quantities after a little storage, which may be caused by the breakdown of eosinophils. It is found in the sputum of patients with bronchial asthma and pulmonary fluke disease.
