 Question: can you have a heart attack from laughing Context: Numerous niche applications exploit the intense color of MG. It is used as a biological stain for microscopic analysis of cell biology and tissue samples. In the Gimenez staining method, basic fuchsin stains bacteria red or magenta, and malachite green is used as a blue-green counterstain. Malachite green is also used in endospore staining, since it can directly stain endospores within bacterial cells; here a safranin counterstain is often used. Malachite green can also be used as a saturable absorber in dye lasers, or as a pH indicator between pH 0.2--1.8. However, this use is relatively rare. Leuco-malachite green (LMG) is used as a detection method for latent blood in forensic science. Hemoglobin catalyzes the reaction between LMG and hydrogen peroxide, converting the colorless LMG into malachite green. Therefore, the appearance of a green color indicates the presence of blood.
 Question: can malachite green be used as a counterstain Context: A miniature pig (also mini pig) is a class of pig developed and used for medical research or as a pet. Miniature pigs weigh between 22.5 kilograms (50 lb) and over 68 kilograms (150 lb) when fully grown. 'Mini pig' has become an acceptable, if imprecise, term that is used to distinguish the difference between large pigs and smaller breeds such as Juliana pigs, Pot-bellied pigs, Choctaw Hog, Kunekune (and specimens derived by cross breeding with these). There are no breeds called teacup, micro, micro mini. These are all adjectives and not breeds of pigs.
