Item Metadata only Ovarian changes during pregnancy and pseudopregnancy in the vole, Microtus agrestis(Society for Reproduction and Fertility, 1970) Breed, W.G.; Clarke, J.R.In the vole, Microtus agrestis, there was no significant change in the number of corpora lutea (cl) during either pregnancy or pseudopregnancy. In pregnant animals, two waves of luteal development took place and histological changes during the two phases of growth differed. In pseudopregnant animals, a similar increase occurred initially which was followed by a marked decrease after Day 8, at which time cl began to degenerate. Luteinized follicles were visible early in pregnancy and pseudopregnancy. Graafian follicles were present after Day 2 or 3. In pregnant animals, the number remained more or less constant, except for a slight increase on Day 19, but their maximum size was reduced at about mid-term, whereas, in pseudopregnant animals, a marked increase in size occurred between Days 8 and 10. Vaginal smears and histology indicated progesterone secretion up to Day 19 of pregnancy and for the 8 to 9 days of pseudopregnancy. There was, therefore, a good correlation between the presence of healthy cl and smears that indicated progesterone secretion.Item Metadata only Reproductive possibilities and estimations of the biological dynamics of earlier human populations(Elsevier, 1976) Henneberg, M.Abstract not availableItem Metadata only Early embryonic development and ovarian activity during concurrent pregnancy and lactation in the hopping-mouse Notomys alexis(CSIRO Publishing, 1981) Breed, W.G.In the hopping-mouse, following a postpartum mating, embryos enter the uterus on about day 5. Implantation occurs on about day 7 if there are no suckling pups, but zona-free blastocysts may remain up to day 18 if from four to seven suckling pups are present. Implantation is eccentric and initially involves interdigitation of trophectoderm and uterine epithelial cells, followed by epithelial cell displacement. The orientation is antimesometrial and, during further development, the embryo invaginates into the yolk-sac cavity. In the ovary, corpora lutea develop during the first few days of pregnancy and then remain unchanged in size or cellular morphology until implantation, regardless of the length of its delay. Peripheral progesterone levels likewise show little change during the preimplantation period. After implantation, a similar number of corpora lutea are found but they increase progressively in size due to luteal cell hypertrophy. The cells show all the organelles typical of steroid hormone synthetic activity and there is a corresponding increase in blood progesterone levels at this time. Vesicular follicles are present throughout concurrent pregnancy and lactation and are larger after implantation. There is no evidence of spontaneous ovulation except at the time of parturition.Item Metadata only Spero-echinocytosis of human red blood cells caused by snake, red-back spider, bee and blue-ringed octopus venom and its inhibition by snake sera(Pergamon, Elsevier Science Ltd., 1995) Flachsenberger, F.; Leigh, C.; Mirtschin, P.Item Metadata only Endstubin: A marker antigen for the endocytic stage of intestinal development in rat, sheep and human(Raven Press, 1995) Trahair, J.

Pre-embedding ultrastructural cytochemistry of rat sciatic and optic nerves was undertaken using anti-EBA, detected with a silver-enhanced gold-conjugated secondary antibody. LM immunocytochemical localisation of EBA was also performed using an HRP-conjugated secondary antibody. EC of pial and parenchymal optic nerve vessels were strongly immunopositive for EBA. Vessels of the dura were negative. At the EM level EBA was observed on the EC luminal surface. In contrast, EC of sciatic nerve were either negative or only weakly immunopositive. The molecular characteristics and function of EBA are largely unknown. Therefore the functional significance of the present findings remains to be determined.Item Metadata only Prolonged effect of hippocampal lesions on rat gastrointestinal crypt cell kinetics(Elsevier, 1995) Callaghan, Brian DesmondItem Metadata only Optic nerve microvessels: A partial molecular definition of cell surface anionic sites(Academic Press, 1995) Lawrenson, J.; Reid, A.; Gajree, T.; Ghabriel, M.; Allt, G.Incorporated in the luminal glycocalyx of vascular endothelia (EC) are negatively charged microdomains (anionic sites). These sites are considered functionally important (a) in their interaction with circulating blood constituents, and (b) as a determinant of vascular permeability. The molecular composition of these EC sites, described for a number of tissues, has demonstrated a heterogeneity dependent on their anatomical location. Luminal anionic sites have not been characterized for EC of optic nerve. Optic nerves were removed from Sprague-Dawley rats previously fixed by vascular perfusion. EC anionic sites were labelled with the probes cationic colloidal gold (CCG) and cationic ferritin (CF), using the pre- and post-embedding techniques, and examined by electron microscopy. The effects of enzyme digestion of ultrathin sections on subsequent CCG labelling were determined using a battery of enzymes in association with the post-embedding technique. CCG labelling was quantified following each enzyme treatment using image analysis software. The biotinylated lectin wheat germ agglutinin (WGA) with streptavidin gold was also used to localize specific monosaccharide residues. The luminal front of intraneural EC showed a uniform labelling with CCG and CF which was greater than on the abluminal surface. Extracellular matrix components and basal laminae were moderately labelled. Digestion of tissue sections with heparitinase and trypsin had no significant effect on subsequent CCG labelling. Proteinase K was less effective than papain but both produced a significant reduction. Neuraminidase almost completely eliminated labelling. CCG binding to the luminal plasma membrane of optic nerve EC can be significantly reduced with proteolytic and glycolytic enzymes. The results demonstrate that sialoglycoproteins principally constitute these luminal EC anionic sites. Biotinylated WGA-streptavidin gold, which detects both N-acetylneuraminic (sialic) acid and N-acetylglucosamine, gave a similar pattern of labelling to CCG alone on the luminal versus abluminal EC fronts. These findings suggest that WGA is binding predominantly to N-acetylneuraminic acid residues since CCG would not label the neutral (uncharged) N-acetylglucosamine.Item Metadata only Spinifex Hopping Mouse-Notomys alexis(Reed Books, 1995) Breed, W.Item Metadata only Variation in sperm head morphology of muroid rodents of Africa: Phylogenetic implications(Memoirs Musee National d'histoire naturelle, 1995) Breed, W.Item Metadata only The popliteus as a retractor of the lateral meniscus of the knee(Saunders, 1995) Jones, C.; Keene, G.; Christie, A.
