Protective and therapeutic effects of okra seed in acute nontraumatic brain injury.

AIM: The purpose of this study was to examine the protective and therapeutic effects of okra (Abelmoschus esculentus [AE]) seed extract, with its known antioxidant, immunomodulatory, and anti-inflammatory properties, in an acetaminophen (paracetamol, N-acetyl- para-aminophenol)-induced model of hepatotoxicity and subsequent acute non-traumatic brain damage. MATERIAL AND METHOD: Forty male Wistar rats were randomly divided into five equal groups, control, paracetamol (P), okra seed extract (AE), okra seed extract + paracetamol (P + AE), and okra seed extract + paracetamol + N-acetyl cysteine (NAC) (P + AE + N). AE was administered by oral gavage through a gastric tube at 600 mg/kg/day for seven days. On the eighth day of the procedure, a single 1 g/kg dose of paracetamol and 300 mg/kg NAC were injected via the intraperitoneal route 1.5 h after AE administration. Rat tissue specimens were subsequently subjected to biochemical and histopathological analyses. Levels of markers such as S100 calcium-binding protein B (S100B), neuron-specific enolase (NSE), and matrix membrane metalloproteinase-9 (MMP-9) were investigated from rat serum specimens. Malondialdehyde (MDA) and superoxide dismutase (SOD) were also measured to determine oxidant-antioxidant status. RESULTS: S100B, NSE, MMP-9, MDA levels, and SOD enzyme activities were examined using biochemical methods. MDA levels were significantly lower in the P + AE group and MMP-9 levels in the AE, P + AE, and P + AE + N groups compared to the P group. Histopathological examination results supported the biochemical findings. CONCLUSION: Okra seed extract exhibits a protective and therapeutic effect against non-traumatic brain damage resulting from acute paracetamol intoxication. We think that this benefit of AE derives from its antioxidant property.

Successful catheter ablation of the accessory pathway in an unusual location in a 13-year-old girl with a coronary sinus diverticulum and Wolff-Parkinson-White syndrome.

Wolff-Parkinson-White syndrome is a congenital cardiac pre-excitation syndrome that is effectively treated by ablating the accessory pathway. However, accessory pathways located in the posteroseptal region can sometimes be challenging. In this paper, we present the successful ablation of the epicardial posteroseptal accessory pathway through the middle cardiac vein in a 13-year-old girl with a coronary sinus diverticulum and Wolff-Parkinson-White syndrome, after unsuccessful ablation attempts at different locations. If the ablation procedure fails, the possibility of the posteroseptal pathway should be kept in mind, and coronary sinus angiography should be performed. In cases with a coronary sinus diverticulum where ablation is not successful, other coronary sinus structures, for example, the middle cardiac vein should be considered as potential accessory pathways.
