| ultrastructure of the reactivated corpus luteum after embryonic diapause in the marsupial, macropus rufogriseus banksianus. | during embryonic diapause in the red-necked wallaby, m.r. banksianus, both the corpus luteum and uterine blastocyst remain dormant, and are reactivated following removal of the suckling pouch young (rpy). the morphology of dormant and reactivated corpora lutea has been studied throughout the 26.5 days of delayed gestation. corpora lutea at 0, 2 1/2, 4, 9, 14, 21 and 25 days after rpy were fixed by perfusion. from day 4 to day 14 after rpy there was a progressive increase in the amount of smooth ... | 1983 | 6831526 |
| milk composition in the red-necked wallaby, macropus rufogriseus banksianus (marsupialia). | 1. milk samples were collected throughout lactation from 10 captive red-necked wallabies. 2. the milk solids content increased throughout lactation and was accompanied by major changes in the relative proportions of protein, lipid and carbohydrate. 3. the carbohydrate fraction consisted of oligosaccharides in the first half of lactation but changed subsequently to monosaccharides. 4. the quantitative and qualitative changes observed were similar to those recorded for other macropodids. | 1989 | 2573463 |
| ultrastructural changes after diapause in the uterine glands, corpus luteum and blastocyst of the red-necked wallaby, macropus rufogriseus banksianus. | pouch young were removed from animals (day 0) captured in the wild in order to reactivate diapausing blastocysts. the blastocyst and tissues from the uterine endometrium and the corpus luteum were preserved for electron microscopy at days 0, 2.5, 4, 5, 6, 9, 14 and 21. at day 0 the diapausing blastocyst is a unilaminar sphere with a diameter of about 260 micrometers. blastocysts up to and including day 6 did not exhibit expansion and no mitotic metaphase stages were found. mitotic activity was p ... | 1981 | 6939863 |
