Earwax of bacteria. Cerumen has been found to reduce the viability of a wide range of bacteria, including "Haemophilus influenzae", "Staphylococcus aureus", and many variants of "Escherichia coli", sometimes by as much as 99%. The growth of two fungi commonly present in otomycosis was also significantly inhibited by human cerumen. These antimicrobial properties are due principally to the presence of saturated fatty acids, lysozyme and, especially, to the slight acidity of cerumen (pH typically around 6.1 in normal individuals). Conversely, other research has found that cerumen can support microbial growth and some cerumen samples were found to have bacterial counts as
Alessandro Achillini body. Achillini compares what he has found during his dissections to what others like Galen and Avicenna have found and notes their similarities and differences. Achillinus states there are seven features when examining the body instead of the believed six given in Galen’s book On Sects. These seven features are size, number, location, form, substance as in thin or thick, substance as in fleshy or bony, and complexion. In this work, Achillinus also gives directions as how to proceed with certain dissections and procedures such as castration, extraction of stone, and removal of the rib cage to further examine the
