Foetus in Hernia

Foetus in Foetu.

Foetus in foetu, a descriptive term attributed to Meckel (circa 1800), should be applied only to those rare cases where a parasitic twin is found included within the abdomen of its partner. Lord (1954; 1956) reported two definite cases and reviewed other possible cases. In contrast, the variety of teratoma which occurs in the retroperitoneal space is much less defined. Since the description of ...

Pyrimidine metabolism in Tritrichomonas foetus.

The anaerobic parasitic protozoa Tritrichomonas foetus is found incapable of de novo pyrimidine biosynthesis by its failure to incorporate bicarbonate, aspartate, or orotate into pyrimidine nucleotides or nucleic acids. Uracil phosphoribosyltransferase in the cytoplasm provides the major pyrimidine salvage for the parasite. Exogenous uridine and cytidine are mostly converted to uracil by uridin...

Foetus acardius amorphus.

drug retention at a time when her dietary intake was below the level of 400 ,zg folic acid-the level shown by Kahn to be necessary to counteract co-trimoxazole antagonism of folic acid. In addition to these factors, however, it may be expected that her folic acid consumption was much higher than normal as she had evidence of a significant haemolytic anaemia. It is well known that a haemolytic a...
