Allantoic cyst and patent urachus
The Indian Journal of Pediatrics, 2008Allantoic cysts of the umbilical cord are extremely rare anomalies. Only few cases have been reported in the postnatal life. The etiopathogenesis is still obscure. We describe a case of allantoic cyst and patent urachus in a newborn associated with hypospadias and meatal obstruction.

Abscess of allantoic duct remnant
American Journal of Obstetrics and Gynecology, 1989A recently submitted placenta was found to be histopathologically unique. Funicitis was present at the early gestational age of 22 1/7 weeks, and an abscessed allantoic duct remnant was present. The latter finding had not previously been seen at this pathology department, nor could reference to it be found in the literature.

Activation and inactivation of allantoate amidohydrolase
Biochimica et Biophysica Acta (BBA) - Enzymology, 1967Abstract Allantoate amidohydrolase from Streptococcus allantoicus has been purified 50-fold by acetone fractionation, DEAE-cellulose chromatography and gel filtration. Mn 2+ was essential for catalytic activity; optimal activity was obtained at IO -4 M Mn 2+ .

The Number of Allantoic Cells in the Chick Embryo
The Journal of Immunology, 1957Summary The number of allantoic cells in the chick embryo has been determined for each day of the second week of incubation. Between the eighth and thirteenth day the number rises from 2.3 × 107 to 1.0 × 108. Part of the increase in number of cells per unit area of membrane is by the formation of a second deeper layer of ...

ALLANTOIN AND ALLANTOATE IN HIGHER PLANTS
Acta Botanica Neerlandica, 1966The amounts of amide nitrogen, ammonia, allantoin and allantoate were determined in Phaseolus hysterinus Dur. and Glycine hispida L. during a growth period of 28 days. P. hys. grown under different conditions showed remarkable differences in the amount of allantoate.

Allantoic cyst and persistent urachal-allantoic communication: A rare umbilical anomaly
Journal of Pediatric Surgery, 1998True cysts of the umbilical cord are distinctly rare. A cyst lined by uroepithelium is described in a newborn in whom the cyst communicated freely with a patent urachal system. It is assumed that this most likely represents a remnant cyst of the allantois--an anomaly not described previously.

A hypothesis on the allantoic origin of the distal midgut
The Anatomical Record, 1986AbstractNo satisfactory explanation for the absence of the ileocecal portion of the digestive system in the newborns with cloacal exstrophy has been offered previously. This is a report of such a case in which the lymphocytes and plasma cells were used as tissue markers to identify the origin of the lymphatic‐rich ileocecal portion of the digestive ...

Chorio‐allantoic membrane touch preparations
The Anatomical Record, 1964AbstractA simple method for separating the ectodermal (chorionic) and entodermal (allantoic) layers of the chorio‐allantoic membrane has been devised. It consists of placing, unfolded, a membrane fragment on a rubber balloon filled with water; air is blown briskly upon the membrane by means of a rubber bulb until its shiny surface becomes dull ...

Catecholamines of the Allantoic Fluid in the Developing Chick Embryo
Nature, 1962ADRENERGIC tissue appears at an early stage in the development of the embryo1 and, in the adult animal, this tissue is the primary source of the catecholamines2. It would be reasonable to inquire whether, during embryogenesis, the activities of developing organs might be influenced by the presence of catecholamines.
