The striated sphincter of the male urethra and its innervation are still a subject of controversy. Essentially, two concepts of its anatomy can be found in the literature. Some authors describe the rhabdosphincter as part of the urogenital diaphragm caudal to the prostate, others as a striated muscle which extends from the base of the bladder to the(More)
PURPOSE To compare and determine the level of agreement of findings at conventional B-mode ultrasonography (US) and sonoelastography of the Achilles tendon with findings at histologic assessment. MATERIALS AND METHODS This study was conducted with the approval of the institutional review boards, and all cadavers were in legal custody of the study(More)
Since the resorption of long-chained fatty acids proceeds exclusively via the lymphatics, the regeneration of lymphatic flow from small bowel grafts takes on a significant role. An isogene, heterotopic small bowel transplant was performed in a total of 54 Lewis rats, whereby 27 animals received no immunosuppression (group A) and the remaining 27 rats(More)
Because hepatocyte transplantation into the spleen or the peritoneal cavity, although successful in rats, is more difficult and less successful in larger animals, the lung was chosen for its accessibility and its high oxygen content as a new site for hepatocyte implantation for treatment of acute hepatic failure. Acute hepatic failure was induced by a(More)
BACKGROUND This study was conducted to assess whether the combined administration of fibrinogen and prothrombin complex concentrate (PCC) enables the reversal of dilutional coagulopathy resulting from intended blood loss and fluid replacement, and whether this treatment reduces further blood loss and mortality. METHODS In 20 anaesthetized pigs,(More)
BACKGROUND This study was conducted to determine whether replacement of fibrinogen is useful in reversing dilutional coagulopathy following severe haemorrhage and administration of colloids. METHODS In 14 anaesthetized pigs, approximately 65% of the estimated blood volume was withdrawn and replaced with the same amount of gelatin solution to achieve(More)
OBJECTIVES We sought to determine the effects of vasopressin and saline placebo in comparison with epinephrine on neurologic recovery and possible cerebral pathology in an established porcine model of prolonged cardiopulmonary resuscitation (CPR). BACKGROUND It is unknown whether increased cerebral blood flow during CPR with vasopressin is beneficial with(More)
OBJECTIVES The hypothesis that the administration of fibrinogen concentrate enables restoration of impaired clot formation and increased bleeding in severe thrombocytopenia was tested. METHODS Thirty pigs were anesthetized, instrumented for blood sampling (routine coagulation tests, modified thrombelastography ROTEM, hemodynamic monitoring and platelet(More)
OBJECTIVE To assess the value of 2 transducer positions for measurement of finger flexor tendon thickness by sonography. METHODS Flexor tendon thickness of the third finger was measured sonographically by 2 independent investigators in 20 healthy volunteers (n = 40 fingers) and in 4 cadaveric specimens (n = 4 fingers). Flexor tendon thickness was measured(More)
To compare agreement between conventional B-mode ultrasound (US) and compression sonoelastography (SEL) of the common extensor tendons of the elbow with histological evaluation. Twenty-six common extensor tendons were evaluated in 17 cadavers (11 females, median age 85 years and 6 males, median age 80 years). B-mode US was graded into: Grade 1, homogeneous(More)
