• Both groups are dabbed for a second time with the same noxious chemical, DNFB.
• Both get a dab of a chemical ( 4-dinitro-fluorobenzene, or DNFB ) on their ears.
• Five rounds of talks were held with ULFA, three rounds with DNFB, with KLO ignoring all invitations sent by the government.
• In the stressed rats, they go straight to the ear _ the spot primed by the DNFB _ park themselves and stand ready to deal with that noxious chemical.
• Sanger used a chemical reagent 1-fluoro-2, 4-dinitrobenzene ( now, also known as Sanger's reagent, fluorodinitrobenzene, FDNB or DNFB ), sourced from poisonous gas research by Bernhard Charles Saunders at the Chemistry Department at Cambridge University.
• Over the next six days, all the rats develop an immunological memory, akin to a vaccination, for DNFB . Should they encounter the chemical again, their immune systems are primed to begin a response, including the swelling and inflammation that result when immune cells rush to the scene.
