Persistent rotavirus infection in mice with severe combined immunodeficiency.

Rotaviruses are important pathogens of human infants and the infants of many animal species. The disease produced by these viruses can be described as an acute, self-limiting diarrheal disease, with virus replication localized to the differentiated epithelial enterocytes of the small intestine. Immunologically normal infants shed virus for approximately 5 to 12 days after the onset of infection.

[Cathepsin D activity in the blood serum of patients in labor and in the serum of extraplacental and neonatal blood].

Cathepsin D in serum of women in labour, retroplacental blood and newborn's blood degradate hemoglobine denatured with urea and the serum protein most intensively in pH 3,5. The denatured protein is more liable to cathepsin D activity than the serum protein. Cathepsin D of the retroplacental blood serum shows the highest activity, the activity in the blood serum of women in labour is lower and it is the lowest in the newborn's blood.
