Des résidus d'anesthésiques les plus anciens découverts sur des outils chirurgicaux chinois

Des résidus trouvés sur des instruments médicaux du XVe siècle révèlent que les médecins chinois utilisaient un composé végétal toxique pour soulager la douleur lors des interventions chirurgicales. Cette découverte constitue la plus ancienne preuve chimique de l'utilisation d'anesthésiques au monde.

Des ciseaux et des pinces chirurgicaux retrouvés dans la tombe du médecin Xia Quan, qui a vécu de 1348 à 1411 dans la province du Jiangsu, portent des traces d'aconitine. Des chercheurs de l'université du Nord-Ouest à Xi'an ont identifié ce composé grâce à une analyse laser. Les instruments avaient été mis au jour en 1974, mais l'étude chimique est récente.

Researchers at the University of Kent, working with University College London, report that madecassic acid—a compound derived from the medicinal herb Centella asiatica and widely used in skincare—can inhibit the growth of antibiotic-resistant E. coli by targeting a bacterial respiratory system not found in humans or other animals.

Experiments suggest Neanderthals could have applied birch tar, found at their sites, as an antiseptic for wounds due to its antibiotic properties. Researchers replicated ancient production methods and tested the tar against bacteria causing skin infections. The findings build on evidence of Neanderthals using medicinal plants.

Chemists at the University of Bristol analyzed the air around tiny fragments of Egyptian mummies to identify volatile organic compounds linked to embalming materials. The study, covering remains from 3200 BC to 395 AD, found 81 distinct compounds from oils, resins, beeswax, and bitumen. These clues show mummification practices grew more complex over time.

Hong Kong customs officers seized 6.5kg of suspected drugs worth HK$3.4 million (US$433,800) and arrested two men in separate operations earlier this week. The Customs and Excise Department said the first arrest took place at Hong Kong International Airport, where 3.1kg of suspected ketamine was found in a 43-year-old man's baggage from Bangkok; the second involved 1.7kg each of suspected cocaine and methamphetamine in Yau Ma Tei.
