GPT and medical procedure: We further evaluated the protective effect of adoptive transfer of BLP‐trained BMDMs on tissue and organ injury in CLP‐challenged mice by selecting serum lactate dehydrogenase (LDH) as an indicator for lung and general cellular damage; creatine kinase (CK) as an indicator for muscle, heart, and brain damage; alanine aminotransferase (ALT) and aspartate aminotransferase (AST) as indicators for liver damage; and blood urea nitrogen (BUN) and creatinine (Cr) as indicators for kidney damage.
