Effects of the duration of transcutaneous CO 2 application on the facilitatory effect in rat fracture repair. J Orthop Sci 2020; 25:886-891. [PMID: 31635930 DOI: 10.1016/j.jos.2019.09.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 08/22/2019] [Accepted: 09/25/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND Carbon dioxide therapy has been reported to be effective in treating certain cardiac diseases and skin problems. Although a previous study suggested that transcutaneous carbon dioxide application accelerated fracture repair in association with promotion of angiogenesis, blood flow, and endochondral ossification, the influence of the duration of carbon dioxide application on fracture repair is unknown. The aim of this study was to investigate the effect of the duration of transcutaneous carbon dioxide application on rat fracture repair. METHODS A closed femoral shaft fracture was created in each rat. Animals were randomly divided into four groups: the control group; 1w-CO2 group, postoperative carbon dioxide treatment for 1 week; 2w-CO2 group, postoperative carbon dioxide treatment for 2 weeks; 3w-CO2 group, postoperative carbon dioxide treatment for 3 weeks. Transcutaneous carbon dioxide application was performed five times a week in the carbon dioxide groups. Sham treatment, where the carbon dioxide was replaced with air, was performed for the control group. Radiographic, histological, and biomechanical assessments were performed at 3 weeks after fracture. RESULTS The fracture union rate was significantly higher in the 3w-CO2 group than in the control group (p < 0.05). Histological assessment revealed promotion of endochondral ossification in the 3w-CO2 group than in the control group. In the biomechanical assessment, all evaluation items related to bone strength were significantly higher in the 3w-CO2 group than in the control group (p < 0.05). CONCLUSIONS The present study, conducted using an animal model, demonstrated that continuous carbon dioxide application throughout the process of fracture repair was effective in enhancing fracture healing.

The Effect of Mofettes on Oxidative Stress/Antioxidant Balance in Experimental Myocardial Ischemia. In Vivo 2020; 33:1911-1920. [PMID: 31662519 DOI: 10.21873/invivo.11685] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Revised: 08/03/2019] [Accepted: 08/08/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND/AIM Natural mofettes are gases resulting from post-volcanic emanations. This study aimed to examine the effect of mofette therapy on plasma oxidative stress and antioxidant parameters in rats after experimental induction of myocardial ischemia, as well as on structural changes in myocardial tissue. MATERIALS AND METHODS White Wistar-Bratislava rats were divided into three groups. In groups 2 and 3, myocardial ischemia was induced by isoproterenol. Rats in group 3 were additionally exposed to high levels mofettes. Oxidative stress and antioxidant parameters were determined in plasma. The structural changes of the myocardium were observed in paraffin embedded slices contrasted using Goldner's trichrome staining. RESULTS A statistically significant change in serum oxidative stress biomarkers, including nitric oxide, malondialdehyde, total oxidant status, as well as in the tested antioxidant molecules and total antioxidant capacity were observed in group 3 compared to group 2. Also, rats of group 3 showed an obvious improvement in inflammatory infiltration and repair of necrotic areas through collagen proliferation (proliferation of fibrous connective tissue) compared to group 2. CONCLUSION Mofette had a beneficial effect on the balance between oxidative stress and antioxidant status following experimentally induced myocardial ischemia.
