• Aspidium — A historical and pharmaceutical name assigned to a genus of ferns (modernly classified mostly under the genus Dryopteris), used in old medical terminology to designate the extract obtained from the rhizome of the male fern (Aspidium filix-mas); its structural compounds act as a potent anthelmintic, historically used in treating intestinal parasite infections.
• Aspirating — Having the property or function of aspiring, absorbing, or drawing a fluid or air through suction; an old technical and physiological term used in 19th-century scientific writings to describe primitive pneumatic devices or anatomical channels that facilitated breathing or fluid absorption.
• Avertin — The historical trade name for tribromoethanol, a chemical compound utilized in the first half of the 20th century as a general anesthetic administered rectally, particularly in pediatric surgery and neurosurgery; due to its narrow therapeutic index and high risk of hepatotoxicity or severe respiratory depression, it was withdrawn from general human clinical use and is now utilized almost exclusively in experimental veterinary medicine and laboratory research on rodents.
• Bacillus — An old, archaic, or phonetically unadapted spelling variant of the modern term 'bacil'; a single-celled bacterial microorganism shaped like a long, thin rod. Used in medical texts from the late 19th and early 20th centuries, the word reflects the early stages of integrating microbiological terminology into academic Romanian, being structurally associated with pathogenic agents responsible for diseases like tuberculosis or plague.
