ABSTRACT
BACKGROUND: The aim of this study was to investigate the anti-inflammatory and antioxidant effects of Coriandrum sativum extract on liver ischaemia reperfusion injury at light microscopic and biochemical levels. MATERIALS AND METHODS: Sham, ischaemia/reperfusion injury (IRI), IRI + Coriandrum sativum extract and only Coriandrum sativum extract groups were formed. Sixty minutes of ischaemia and 60 minutes of reperfusion were performed. In the treatment group, 300 mg/kg/day Coriandrum sativum was given by gavage. Hepatic tissues were fixed in 4% paraformaldehyde. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) enzymes were measured. Nuclear factor-kappa beta (NF-κB), tumour necrosis factor-alpha (TNF-α) and caspase-3 immunohistochemistry staining was performed. Microscopic scoring was performed in terms of sinusoidal congestion, vacuolisation, and necrosis. RESULTS: Sinusoidal enlargement and diffuse congestion, Kupffer cell increase, neutrophil increase in necrotic areas, vacuolisation in hepatocytes, and bile duct proliferation in the portal triad were observed in ischaemia/reperfusion hepatic tissue. Very rare, necrotic areas were observed in the Coriandrum sativum treatment group, while congestion and vacuolisation and bile duct proliferation were decreased compared to the ischaemic group. The AST and ALT levels were increased in the IRI and IRI + Coriandrum sativum groups. When compared to the IRI group, the AST and ALT levels of the Coriandrum sativum were considerably decreased. The IRI and IRI + Coriandrum sativum groups had statistically significant differences in ALP compared to that of the Coriandrum sativum and Sham groups. There was no significant difference between the ALP levels of the IRI and IRI + Coriandrum sativum groups TNF-α, NF-κB and caspase-3 immune positive stained hepatocytes were numerous and widely observed in the injury group. There were positive TNF-α immunohistochemical staining Kupffer cells in the IRI group. In the group treated with Coriandrum sativum, Kupffer cells were not stained, while TNF-α, NF κB and caspase-3 expressing hepatocytes were found to be decreased compared to the IRI group. When the expression values of the TNF-α, NF-κB and caspase-3 groups were evaluated statistically, it was seen that there was a significant decrease in the group treated with Coriandrum sativum. CONCLUSIONS: It was found that Coriandrum sativum extract decreased proinflammatory cytokine TNF-α and apoptotic cell death and liver enzymes in liver ischaemia/reperfusion injury.

A 22-year-old woman presented with bilateral thickening and hyperpigmentation of her nipples since the age of 17 years. There was no history of pregnancy or oral contraceptive pill use. Isotretinoin 0.025% gel was applied twice daily and the lesions disappeared in 4 weeks. After the drug was ceased, recurrence appeared within 4 months. The same therapy, applied for 2 weeks, again cleared the problem.

During an eight-year period 887 patients with symptoms of hemorrhoids were treated at the Department of Surgery and Outpatient Care of the Vaszary Kolos County Hospital, Esztergom. 178 patients with first degree hemorrhoids received only conservative treatment. Rubber band ligation (RBL) which can be performed on outpatients was applied in 324 patients with first, second and third degree hemorrhoids. Thrombosed external hemorrhoids were treated by excision in 215 patients. Hemorrhoidectomy (H) was mainly carried out in 91 cases for treatment of circular 3rd and 4th degree nodules involving complications. More than 80 per cent of the patients receiving rubber band ligation and hemorrhoidectomy were followed up. 65% of the RBL group and 85% of the H group were symptom free, while 76% of the RBL group and 91% of the H group showed great improvement after the treatment. Personal results, complications, and review of the literature are discussed in detail.
