Preliminary Study on the Tears Oxidative Stress Status and Sleep Disturbances in Irritable Bowel Syndrome Patients

Figure 5

Studied oxidative stress markers in IBS patients’ tears, stratified by patients’ sex and IBS subtype. (a) Superoxide dismutase activity (U/mg proteins). (b) Glutathione peroxidase activity (U/mg proteins). (c) Malondialdehyde concentration (mmol MDA/mg proteins). (d) Total soluble proteins (mg/ml tears). The results are expressed as ( for control, 10 for IBS, 7 for IBS-C, and 3 for IBS-D, ).
