Some interesting images of the inflammation seen in early stages of rheumatoid arthritis (RA) were released recently.
These images use a special type of fluorescent dye that is activated by the infrared radiation released at the site of inflammation. The intent of the project is to develop a way to detect such inflammation at an early stage of RA, when there's still time to help avert some of the damage produced by this condition.
However, the images can be useful in your A&P course when discussing the process of inflammation. The images are a dramatic example that contrasts the heat present in a normal hand versus the heat produced by hands that are inflamed.
