Prevention of tissue damage after testicular torsion caused by I/R injury is still a clinical and experimental problem. There are many experimental studies made with several chemicals in the literature for decreasing the effect of reactive oxygen species after ischemia and reperfusion. Dexpanthenol (Dxp) is the biologically active alcohol of pantothenic acid. Pantothenic acid increases the content of reduced glutathione, Coenzyme A and ATP in cell. We studied the effect of Dxp on lipid peroxidation and testicular damage. Forty adult rats were separated randomly into five groups: group Sh, Sham-operation; group TD, torsion-detorsion; group NS, torsion-normal saline-detorsion; group D, torsion-Dxp 250 mg/kg detorsion; group D2, torsion-Dxp 500 mg/kg detorsion group. Serum MDA levels were taken before detorsion, after torsion at the first and fifth minute and at the first hour. Tissue sample was taken at the first hour. The alterations of I/R injury on testis were histological graded. Serum MDA levels were significantly lower in group D2 compared to all groups. The histopathology score of group D2 was significantly lower than groups TD, NS and D. Histopathological score and serum MDA levels are strikingly compatible. Dxp attenuated lipid peroxidation and tissue damage at I/R injury. This effect depends on its antioxidant effect with increasingly reduced glutathione, Coenzyme A and ATP. The effect of Dxp on I/R injury has been shown for the first time in the experimental testicular torsion.
Intestinal obstruction caused by an anomalous congenital band is very rare in adults and children. A 7-year-old boy was admitted with acute intestinal obstruction. His parents mentioned that the child always had mild abdominal distention and failure to thrive from his infancy. On his medical history, there were not any attacks of abdominal pain, fever and hospitalization. Laparotomy showed an ileal loop compressed by an anomalous band, which extended from the ileum to the sigmoid mesentery resembling a mesenteric remnant. The band was resected. Histologically, it was composed of loose connective tissue containing mature vessels.
Gradual detorsion can reduce reperfusion injury in a rat model of ovarian torsion. This method is easily applicable and may be a useful method for human patients with ovarian torsion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
