comparison of rate of hepatic metabolism in vitro and half-life for antipyrine in vivo in three species.1. a radiometric assay for the total metabolism of antipyrine in vitro by hepatic microsomal preparations has been developed. 2. apparent km and v values for the process were determined in rats, rabbits and in a marsupial (the quokka; setomix brachyurus). km values were similar in rats and rabbits (3.5 and 5 mm respectively) but were somewhat lower in quokkas (1.4--1.5 mm). estimates of v ranged from 49--64 nmol/mg microsomal protein/10 min and were similar in all three species. pretreatment of ...1979433309
estimation of michaelis--menten constants in microsomal enzyme systems by the direct linear plot and least squares regression.1. data from in vitro liver microsomal metabolism of ethylmorphine aniline and benzpyrene in male rats and male and female quokkas (setonix brachyurus) were fitted to the michaelis--menten equation by wilkinson's non-linear regression procedure and eisenthal and cornish-bowden's direct linear plot. 2. ethylmorphine and aniline metabolism in the male quokka were non-ideal, but in all other instances there were no differences in the performance of the two methods.1978685293

induction of long-term tolerance in the quokka (setonix brachyurus) by thymus and skin allografts into early pouch young.intact quokkas (setonix brachyurus) were grafted with thymus and skin as neonates. fifty seven percent of primary thymus grafts persisted when donors were less than 32 days of age, compared with only 20% when the dornors were juveniles. this suggested that neonatal tissue was more readily accepted than tissue from adult animals. when the recipients had left the pouch, induced tolerance was tested by grafting thymus and skin from the original donors. second thymus grafts were generally unsuccessf ...1978375905

marsupial immunoglobulins: the distribution and evolution of macropod igg2, igg1, igm and light chain antigenic markers within the sub-class metatheria.the distribution within australian and american marsupials of the heavy and light chain antigenic markers identified by antisera to purified quokka (setonix brachyurus) immunoglobulins is described. markers for igm and igg2 constant region determinants as well as for light chains were widely distributed in australian species and were also detected in didelphis, the american opossum, thus indicating a long-term structural conservatism of some immunoglobulins within the marsupials. more detailed a ...197773503

temperature regulation and oxygen consumption in the developing macropod marsupial setonix brachyurus.1. when kept at ambient temperatures of 17-5 and 24 degrees c the colonic temperatures of joeys younger than 166 days declined to near ambient temperature. pouch joeys of 166 days and older were however able to maintain their colonic temperatures at about 35 degrees c. 2. joeys first developed the ability to sustain high o2 consumption rates in response to cooling, when aged between 144 and 169 days. only when this latter facility was fully developed in ontogeny could body temperature be maintai ...1977894610
the in vitro response to phytomitogens of marsupial leukocytes.leukocytes from two macropod marsupials, the quokka (setonix brachyuras) and the tammar (macropus eugenii) were separated from whole blood by dextran sedimentation and established in culture with either phytohemagglutinin-p, concanavalin a, or pokeweed mitogen. the leukocyte response to each mitogen, as measured by the incorporation of tritiated thymidine into dna, was similar to that described in other experimental systems. these results suggest that the functional elements of the cellular immu ...1976979144
mixed function oxidase activity in a marsupial. the quokka (seton;x brachyurus).components of the cytochrome p-450 pathway and rates of oxidative hepatic metabolism of the substrates, ethylmorphine, 3,4-benzpyrene, and aniline, have been investigated in a marsupial (the quokka, setonix brachyurus) and compared with those of the rat. in general the quokka had lower rates of drug metabolism and higher km values than those found in the rat. sex differences in vmax and km were also found for the quokka. these species and sex differences in oxidative drug metabolism did not corr ...19766222
blood corticosteroids in australian marsupial and placental mammals and one monotreme.peripheral blood corticosteroid levels were determined in nine species of australian marsupial (eastern grey kangaroo, black-tailed, bennett's and pademelon wallabies, quokka, wombat, koala and western native and tiger cats), one species of monotreme (echidna) and one placental australian mammal (dingo). animals were obtained or bled with minimal disturbance and came from areas considered to have adequate sodium content of the vegetation. aldosterone, corticosterone, cortisol, 11-deoxycorticoste ...1976181514

histamine in the tissues of the marsupial setonix brachyurus (the quokka).passive cutaneous anaphylactic (pca) reactions in the marsupial setonix brachyurus (the quokka) were completely inhibited by the histamine antagonist mepyramine maleate, but were unaffected by disodium cromoglycate or the serotonin antagonist, methysergide. histological examination of quokka skin indicated that mast cell degranulation occurred during the pca reaction in this marsupial and animals whose skin was relatively deficient in mast cells were poor pca recipients. in contrast to many euth ...1975234921

development of lymphoid tissue in a marsupial, setonix brachyurus (quokka).the development of the lymphoid tissues in a macropod marsupial is described. the liver is the only functional haemopoietic tissue at birth. large lymphocytes first appear in the cervical thymus at 2 days, and in the thoracic thymus at 4 days after birth. small lymphocytes appear 1-2 days later. the histological development of the two glands is similar, but the thoracic thymus develops much more slowly than the cervical. the appearance of hassall's corpuscles in both thymus glands correlates wit ...19751154997

immunoglobulin classes carrying homocytotropic and passive hemagglutinating antibody activities in the marsupial setonix brachyurus (the quokka).on the basis of their physicochemical and antigenic properties, and by analogy with guinea pig immunoglobulins, two antibody classes in the serum of the marsupial setonix brachyurus have been classified as igg1 and igg2 isotypes. the analogy between these marsupial immunoglobulins and those of eutherian (placental) species was extended by an investigation of their biological activities. the electrophoretically slow antibody (igg2) fixed hemolytic complement, precipitated soluble antigen and pred ...1975803934

salmonella javiana infection in an infant associated with a marsupial, the quokka, setonix brachyurus, in western australia.salmonella javiana, a serotype rarely isolated in australia, has been recovered from the faeces of a 14-month-old infant with symptoms of enteritis.the child had been closely associated with a marsupial species, the quokka, during a vacation on rottnest island in western australia, and s. javiana was isolated from faecal pellets from adult quokkas, and also from a snake collected on the island.sampling revealed a high incidence of salmonella infection in the quokkas. in all, 62 out of 87 animals ...19734518341

oxygen consumption during pouch development of the macropod marsupial setonix brachyurus.1. measurements of o(2) consumption at 9 or 10 temperatures in the 20-40 degrees c ambient temperature range were made on joeys with ages selected to cover the 180-day period of pouch occupancy.2. the rate of o(2) consumption of joeys younger than 100 days increased directly with ambient temperature.3. after 100 days of age the o(2) consumption rate at low temperatures rose and at about 140 days of age a constant rate was maintained over the full ambient temperature range.4. heat transfer from j ...19665972171
