Chemotactic Factor Inactivator In Normal Human Serum., J L Berenberg, P A Ward May 1973

Chemotactic Factor Inactivator In Normal Human Serum., J L Berenberg, P A Ward

SoM Articles

Normal human serum contains an inactivator of chemotactic factors for neutrophilic leukocytes. The chemotactic factor inactivator (CF-I) remains soluble when serum is fractionated with ammonium sulfate (at 45% saturation), directly and irreversibly inactivates chemotactic factors, and it has a broad spectrum of activity as indicated by its inactivation of the chemotactic fragments of human C3 and C5 (third and fifth components of complement), C5̅6̅7̅, and the bacterial chemotactic factor derived from Escherichia coli. CF-I appears as a biphasic activity according to preparative techniques of sucrose density ultracentrifugation, electrophoresis, and gel filtration. Studies on the interaction of CF-I with the radiotagged …

Studies On The Ascaris Lumbricoides, H. M. Martin Dec 1926

Studies On The Ascaris Lumbricoides, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The Ascaris lumbricoides, in one phase or another, has attracted the attention of parasitologists for many years, and during the last decade this parasite has been studied by a large number of investigators. The recent observations have been, to a great extent, directed along one line, the study of its life history. These investigators have established two important points: (a) That the life history of Ascaris is more complex than was supposed, as it has been found that a vasculo-pulmonary circuit of the larvae is necessary before they settle down in the intestine, where they develop to the adult …
