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.

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.

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 ...

Allantoate and ureidoglycolate degradation by Pseudomonas aeruginosa
Biochimica et Biophysica Acta (BBA) - Enzymology, 1967Abstract 1. 1.|A single enzyme, allantoicase (allantoate amidinohydrolase, EC 3.5.3.4), catalyzes the conversion of allantoate to (−)-ureidoglycolate. On the other hand, two enzymes were found to be responsible for the degradation of ureidoglycolate by Pseudomonas aeruginosa extracts: allantoicase, which degraded (+)-ureidoglycolate by 3–4 times ...

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.

Catabolism of allantoate and ureidoglycolate in Rana esculenta
Comparative Biochemistry and Physiology, 1969Abstract 1. 1. The activities of allantoicase and ureidoglycolase in frog ( Rana esculenta ) liver and kidney extracts were determined. Allantoate amidohydrolase was not involved in allantoate catabolism in frog liver and kidney. 2. 2. Allantoate was converted to urea and (−)-ureidoglycolate by allantoicase and ureidoglycolate was further ...

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 ...
