Experimental Vibrio Infections of Developing Chick Embryos
Developing chick embryos are highly susceptible to infection with strains on V. cholerae representing Gardner and Venkatraman's 6 groups and the types Inaba and Ogawa. There is a moderate decrease in susceptibility with advancing age of the embryo. The influence of dosage on survival rates is not marked, probably because a minimal dose, consisting of a very few organisms, is sufficient to produ...
متن کاملCarbonic anhydrase activity in early developing chick embryos.
CHANGES in tension of environmental CO2 gas have been shown to affect cellular differentiation. In the presence of increased partial pressure of dissolved CO2(/?Co2) Loomis (1957) has demonstrated an increase in sexual differentiation of hydra and Flickinger (1958) has caused explanted frog ectoderm to differentiate into neural tissue. Loomis was able to show that the substance which stimulates...
متن کاملCardiac outflow tract malformations in chick embryos exposed to homocysteine.
OBJECTIVE Increased homocysteine concentrations have been associated with cardiac outflow tract defects. It has been hypothesized that cardiac neural crest cells were the target cells in these malformations. Cardiac neural crest cells migrate from the neural tube and contribute to the condensed mesenchyme of the aorticopulmonary septum and outflow tract cushions of the heart. The aim of this st...
متن کاملHistological studies on developing chick embryos treated with aminoguanidine sulfate.
Fertile eggs were injected 10 or 20 mg/egg of aminoguanidine sulfate (AGS) into the albumen on the 5th day of incubation and examined macroscopically and histopathologically. The marked abnormalities were observed in liver, gallbladder and spleen while other organs were not different from the control. The earliest change was an increase of mitotic cells in the liver which reached to the peak at...
متن کاملTeratogen-induced activation of p53 in early postimplantation mouse embryos.
Hyperthermia (HS) and 4-hydroperoxycyclophosphamide (4CP) activate the mitochondrial apoptotic pathway in day 9 mouse embryos. Previous microarray analyses Microarray analyses revealed that several p53 target genes are upregulated after exposure to HS or 4CP, suggesting a role for p53 in teratogen-induced apoptosis. To explore the role of p53, we assessed the activation of p53 in day 9 mouse em...
