SUMMARY AND CONCLUSIONS The hemorrhagic syndrome which occurred after the iv inoculation of ground embryo extract into living chicken embryos resulted from rapid activation and depletion of the clotting mechanism. The syndrome was prevented by the addition of heparin to the ground embryo inoculum. The characteristics of the hemorrhagic syndrome suggest

Malformations in Chicken Embryos in the Northeast
Science, 1988In Deborah Barnes' article "Joint Soviet-U.S. attack on heart muscle dogma" (Research News, 14 Oct., page 193), credit for a photograph was inadvertently omitted. John Oberpriller of the University of North Dakota graciously supplied the photograph of a newt ventricular myocyte dividing in culture.

The Effect of Stevia on the Chicken Embryo Heart
Cardiovascular & Hematological Disorders-Drug Targets, 2016Stevioside is one of the most important food additives that has become well known for its sweetness. The aim of this study was to evaluate the impact of Stevioside on the heart.4-day-old embryonated chickens eggs were inoculated with Stevioside and kept until hatching.

Arterial anatomy of chicken embryo and hatchling
American Journal of Anatomy, 1984AbstractThe arterial pattern in chicken hatchlings was investigated by microangiography and microscopic analysis of cleared specimens. The hatchling arterial pattern was found to resemble strongly the pattern that has been described for the adult chicken. Several minor variations in this pattern were found which were probably due to species, strain, or

Thyroxine and duodenal development in chicken embryos
Canadian Journal of Zoology, 1979To test whether thyroxine (T4) can stimulate duodenal development in chickens, it was administered to 16.5-day-old embryos (strain Hyline 934F of Gallus gallus) (approximately stage 42). Treatment time was closer to the prehatching phosphatase increase, and the single dosage (5 μg) larger than before.

Oxygen analyses of chicken embryo blood
Respiration Physiology, 1977According to data obtained previously on the blood gas tensions and the oxygen dissociation curve of chicken embryos, the arteriovenous oxygen saturation difference in the allantoic circulation has been conjectured fairly large. In order to confirm this conjecture as well as to check the validity of the in vitro dissociation curve, both the blood ...

Evaluation of anticoccidial drugs in chicken embryos
Parasitology Research, 1991Infections of Eimeria tenella in chicken embryos were used to compare the anticoccidial activity of ten drugs. The minimal inhibitory concentration (MIC) and minimal toxic concentration (MTC) were affected by the time of inoculation into the embryos and by the chemical nature of the compounds. Some compounds (nicarbazin, amprolium) had no effect on the

Pasteurella multocida infection in the chicken embryo
Journal of Comparative Pathology, 1998Pasteurella multocida infection in embryonated chicken eggs was studied by chorio-allantoic membrane inoculation. Strain differences were demonstrated in terms of lesion severity and time to death, especially during the first 24 h post-inoculation. A strain of low virulence gave a clear dose response but more virulent strains did not.

Malpositions in chicken‐pheasant hybrid embryos
British Poultry Science, 1974Synopsis The occurrence of malpositions in hybrid embryos obtained by two‐way crosses between Ring‐necked pheasants (Phasianus colchicus) and Columbian Rock fowls (Gallus domesticus) was examined and the numbers of the various types of malpositions were recorded. Of the 230 unhatched embryos, the 178 embryos which were detected to be more than 18 d old
