Excision of ectopic adrenocortical tissue during laparoscopy for isolated tubal torsion
2017
Ectopic adrenal tissue is an occasional finding during surgery procedures. These remnants are usually found near the primary gland or along the course of gonadal vessels consistently with embryologic development. The appearance is of a small but distinct, soft, round, yellow nodule and only cortical adrenal tissue is normally observed. We report a case of an emergency laparoscopic salpingostomy for isolated tubal torsion with excision of EAT, incidentally found in left ovarian pedicle, followed by postoperative resumption of regular menses and regression of hirsutism. Although intraoperative research of ectopic adrenal tissue is not necessary its removal is indicated in case of incidental f…
Determination of renal tissue ibandronate levels in rats with normal and mildly impaired renal function
2013
After entering the blood, bisphosphonates are immediately bound to bone or excreted unchanged by the kidney. During renal excretion about 0.5% of administrated dosage remains in kidney tissue. The renal tissue level of bisphosphonates (RTL) decreases over time and remains at about 0.15% after 3weeks, but the influence of renal insufficiency (RI) is unclear.We investigated the influence of mild to moderate RI on RTL of ibandronate (IBD). First a method for determination of RTL was implemented and validated. We measured RTL in rats with normal renal function (SHAM) and after unilateral nephrectomy (UNX). In each case one SHAM and one UNX groups received one or alternatively 9 times every 3wee…
Cholestenon in Rattennebennieren
1970
For the first time it has been proven that cholest-4-ene-3-one is an endogenous constituent of adrenal tissue. Concentrations of cholestenone in quartered rat adrenals after 3 hours of in vitro incubation were comparable to those of progesterone. However, from specific radioactivities of tissue cholesterol and progesterone and from those of tissue cholestenone and progesterone after incubations with either 4-14C-cholesterol or 4-14C-cholestenone it has been concluded that, at best, cholestenone plays a minimal role as a C27-intermediate of corticosteroid biosynthesis.
