IgE antibodies that bind the muscle relaxant alcuronium were found in sera from six patients who experienced anaphylactic-like reactions following administration of the drug during induction of anaesthesia. Drug-specific antibodies were detected by radioimmunoassay employing a covalently coupled alcuronium-Sepharose complex and 125I-labelled anti-human IgE.(More)
The ultrastructure of hepatocytes, bile canaliculi, and hepatic sinusoids of the larval lamprey, Petromyzon marinus, was examined using thin-sectioned and freeze-fractured tissues. The liver is a "tubular gland" with hepatocytes arranged in a tubular fashion around large bile canaliculi. Hepatocytes are roughly conical in shape, with their tapered apices(More)
The arterial terminations were studied by scanning electron microscopy of microvascular casts in rat, hamster and human livers. Important species differences were observed. In the rat, frequent anastomoses between the terminal hepatic arterioles and portal venules were observed, whereas a few arterioles terminated directly into sinusoids. On the contrary,(More)
Regulation of cell proliferation and motility is essential for normal development. The Rho family of GTPases plays a critical role in the control of cell polarity and migration by effecting the cytoskeleton, membrane trafficking, and cell adhesion. We investigated a recognized developmental disorder, Adams-Oliver syndrome (AOS), characterized by the(More)
Ophthalmo-acromelic syndrome (OAS), also known as Waardenburg Anophthalmia syndrome, is defined by the combination of eye malformations, most commonly bilateral anophthalmia, with post-axial oligosyndactyly. Homozygosity mapping and subsequent targeted mutation analysis of a locus on 14q24.2 identified homozygous mutations in SMOC1 (SPARC-related modular(More)
Intradermal testing has been used in the diagnosis of acute anaphylactic reactions during anaesthesia in 51 patients. Positive results occurred in 32 patients and confirmation was possible in 26. Only in one case did a combination of history and intradermal testing not give a diagnosis. Nine of the negative results were confirmed. Intradermal testing is of(More)
One thousand patients undergoing anaesthesia in an Australian hospital were assessed by questionnaire to determine the incidence of previous anaesthesia, allergy and atopy. The patients were compared with a British group and with 85 patients who had life-threatening anaphylactoid reactions. The Australian and British groups were not significantly different.(More)
Two patients who experienced cardiovascular collapse due to anaphylactoid reactions are described. The first patient showed haemoconcentration which was rapidly restored with colloid solutions and vasoconstrictors. The second patient showed haemoconcentration in spite of massive infusion of crystalloid and repeated adrenaline; her circulatory status was(More)
