The effect of Farnesoid X receptor agonist tropifexor on liver damage in rats with experimental obstructive jaundice.

PURPOSE: To investigate experimentally the effects of Tropifexor, a farnesoid X receptor agonist, on liver injury in rats with obstructive jaundice. METHODS: Forty healthy Wistar albino female rats were divided randomly in selected groups. These groups were the sham group, control group, vehicle solution group, Ursodeoxycholic acid group and Tropifexor group. Experimental obstructive jaundice was created in all groups, except the sham one. In the blood samples obtained, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), total bilirubin and direct bilirubin levels were established and recorded. Additionally, liver malondialdehyde, myeloperoxidase and catalase enzyme activity in the tissue samples were studied. Histopathological analysis was also performed. RESULTS: No statistical difference was found between the control group and the Tropifexor group when AST, ALT and ALP values were compared. However, it was found that the Tropifexor group had statistically significant decreases in the values of GGT, total bilirubin and direct bilirubin (p < 0.05). Additionally, Tropifexor decreased the median values of malondialdehyde and myeloperoxidase, but this difference was not statistically significant compared to the control group. Finally, the Tropifexor group was statistically significant in recurring histopathological liver damage indicators (p < 0.05). CONCLUSIONS: Tropifexor reduced liver damage due to obstructive jaundice.

[Effects of music therapy on pain and oxidative stress in oocyte pick-up: a randomized clinical trial]. / Efeitos da musicoterapia sobre dor e estresse oxidativo na aspiração folicular: estudo clínico randomizado.

BACKGROUND AND OBJECTIVE: The aim was to investigate the effects of Turkish classical music on pain and oxidative stress in patients undergoing oocyte pick-up. METHODS: The study was a randomized, controlled trial. The groups included were Group NM (Non-Music), control group; Group PM, which comprised patients who listened to music before the operation; and Group CM, which comprised patients who listened to music both before and during the operation. Blood was drawn prior to the operation to measure the oxidative stress values. Pain, hemodynamic parameters, oxidative stress values were assessed postoperatively. RESULTS: The number of patients requiring additional propofol was higher in Group PM than in Groups NM and CM (p=0.003). The postoperative Visual Analog Scale (VAS) score were lower in Groups PM and CM than in Group NM (p=0.001, p=0.007) in the 1st and 60th minutes. The postoperative VAS score was lower in Group CM than in Group NM (p=0.045) in the 5th minute. The postoperative additional analgesic requirements were lower in Groups PM and CM than in Group NM (p=0.045). The postoperative blood glutathione peroxidase values were significantly higher in Groups PM and CM than in Group NM (p=0.001). The postoperative catalase values were significantly higher in Groups PM and CM than in Group NM (p=0.008 and p ≤0.001). The preoperative malondialdehyde values were significantly lower in Groups PM and CM than in Group NM. The preoperative nitric oxide values were higher in Groups PM and CM than in Group NM (p ≤0.001), whereas the postoperative nitric oxide values were lower in Groups PM and CM than in Group NM (p ≤0.001). CONCLUSION: Turkish classical music has beneficial effects on pain and oxidative stress in oocyte pick-up patients.
