JACKSON, MISSISSIPPI—According to a Live Science report, a “porcelain gallbladder” has been identified among a woman's 100-year-old bones exhumed from the cemetery at the site of the Mississippi State Lunatic Asylum, which operated from 1855 to 1935. A porcelain gallbladder forms through calcium build-up in the wall of the organ, which causes it to harden. A micro-CT scan conducted at the University of Mississippi Medical Center showed that this woman’s gallbladder also contained a large gallstone. “It’s funny that the object was initially an exciting mystery for the bioarchaeologists,” said bioarchaeologist Jennifer Mack, “whereas it was identified almost at a glance by the retired surgeon on our project.” Gallstones were detected in another five people buried in the asylum cemetery, where as many as 7,000 people may have been buried.
