The oxygen and carbon dioxide tension were studies with Silastic tonometer technique in skeletal muscle and subcutaneous tissue of rat. The high initial pO2 was caused by airborne contamination during implantation and declined rapidly. Tissue gas tensions measured with a Silastic tonometer reflect the healing sequences of implantation trauma and stable readings are not obtained until 14 days after implantation. After healing of implantation injury 42 to 47 mmHg pO2 and 50 to 57 mmHg pCO2 were measured in muscle and 23 to 26 mmHg pO2 and 51 to 57 mmHg pCO2 in subcutaneous tissue of rat.
采用硅橡胶张力计技术研究了大鼠骨骼肌和皮下组织中的氧分压和二氧化碳分压。初始高pO₂是由植入过程中的空气污染引起的，并迅速下降。用硅橡胶张力计测量的组织气体张力反映了植入创伤的愈合过程，直到植入后14天才能获得稳定读数。植入损伤愈合后，在大鼠肌肉中测得pO₂为42至47 mmHg，pCO₂为50至57 mmHg；在皮下组织中测得pO₂为23至26 mmHg，pCO₂为51至57 mmHg。
