Quality aspects of culture media for enterobacteriaceae

Identification of mononuclear cells in human blood. II. Evaluation of morphological and immunological aspects of native and formaldehyde-fixed cell populations

The presence of surface-associated immunoglobulins and Fc receptors on mononuclear cells from normal human blood waas investigated by the direct immunofluorescence technique combined with phase-contrast microscopy. Formaldehyde-fixed cells were compared to unfixed cells and to cells preincubated at 37??C. In the unfixed samples a separate...

High activity of glucose-6-phosphate dehydrogenase in Kupffer cells isolated from rat liver

Analysis of tumour responses by excision and in vitro assay of cellular clonogenic capacity

Further studies on mobilization of CFUs

Mobilization of CFUs from haemopoietic tissues into circulation was studied after injection of different bacterial lipopolysaccharides (LPS), zymosan, phytohaemagglutinin (PHA), concanavalin A (Con A), trypsin and di-isopropyl-fluorophosphate-inhibited trypsin. All bacterial LPS used gave an increase of CFUs in the peripheral blood at 1 h after...

Successful oxime therapy one hour after soman intoxication in the rat

The bisquarternary mono-oxime HI-6, and to a lesser extent HS-6, caused functional recovery of neuromuscular transmission in vivo and in vitro when given 60 min after soman, i.e. when the soman-cholinesterase (AChE) complex is said to be fully 'aged'. Atropinised rats, with the tracheas intubated, received 4 x LD50 soman i.v. and were kept alive...

Inhibitory effect of some Perigotype compounds on clostridium spores in pastuerized meat products

The regulation of cell proliferation and differentiation in intestinal epithelium. II. A quantitative histochemical and autoradiographic study after low doses of X-irradiation

To investigate the biochemical mechanisms involved in the regulation of cell proliferation and differentiation the intestinal epithelium has been chosen because of the regular distribution of proliferative-, non-dividing maturing- and functional cells along the crypt and villus. The effect of low doses of irradiation (50-400 R) which selectively...

Ervaringen met zgn. Agarworsten volgens Ten Cate als hulpmiddel bij het hygiënische slachtlijnonderzoek

"Taking prints" by Ten Cate's so-called agar sausages was found to be a very useful method in sanitary line-studies in poultry processing plants. To prevent the spread of marginal infection of the sausages, however, the scalpels had to be stored in seventy per cent alcohol. The parallel use of violet-red-bile glucose agar and brilliant-green...
