As an alternative, the medetomidine\u2010midazolam\u2010butorphanol (MMB) combination is commonly used in Japan. However, medetomidine is a racemic mixture containing the inactive R\u2010enantiomer, which may reduce anesthetic predictability and safety.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>The aim of the study was to evaluate the efficacy and safety of a modified anesthetic combination (dMMB), in which dexmedetomidine replaces medetomidine, across three commonly used mouse strains (ICR, C57BL\/6, BALB\/c).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Male and female mice were administered either MMB or dMMB subcutaneously.

Body temperature recovery was significantly enhanced in dMMB\u2010treated B6 males. No significant differences in side effects (ocular opacity or blood glucose levels) were observed between protocols, though strain\u2010specific glucose elevations were noted in dMMB\u2010treated males.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>dMMB is a safe, effective, and ketamine\u2010free injectable anesthetic protocol, offering advantages in recovery and thermoregulation.
