India ink and cartilage.

摘要

In the article on Basic methods in histopathology of joint tissues a method is described for macroscopic evaluation of cartilage by 'staining with Indian ink' (sic). The description of the method suggests using 'blue Indian ink (Parker, Quink)'. There appear to be some misunderstandings here that are worth clarifying for the benefit of anyone wishing either to use these methods or to understand published papers that have used these techniques.
