Histological findings of the internal inguinal ring in patients having indirect inguinal hernia
BACKGROUND: Aiming to deepen the understanding of the factors involved in the genesis of groin hernia, this study is focused on identifying the histological changes within the muscle fibers of the internal inguinal ring in patients having indirect inguinal hernia. METHODS: In eight patients with primary or recurrent bilateral indirect inguinal hernia who underwent a Stoppa open posterior inguinal hernia repair, a tissue specimen from the edge of the internal inguinal ring was biopsied and histologically examined. RESULTS: In all of the tissue samples, remarkable degenerative changes such as fibrohyaline degeneration of the muscle fibers, vascular congestion, and phlogistic infiltration thro…
ALLELIC VARIANTS OF CYP2E1 GENE IN HEPATOCARCINOMA PATIENTS AND IN HEPATIC TUMOR CELL LINES
Background and Aims: Hepatic enzyme CYP2E1 is involved in the metabolism of a number of exogenous and endogenous substances (i.e. ethanol, drugs and chemical carcinogens). Being polymorphic, CYP2E1 gene can give different xeno-metabolic capabilities in a population and it is well known that inadequate or no enzymatic deactivation of xenobiotics could induce an increased susceptibility to disease and cancer. In particular, one of the 5 -flanking region polymorphisms, able to differentiate CYP2E1 gene transcriptional activity, is caused by the appearance/disappearance of RsaI and PstI restriction sites, which generates two different alleles, namely *C1(Rsa+/Pst−) and *C2(Rsa−/Pst+) respective…
