Phagocytes – cells of nonspecific and specific resistance

Specific and Nonspecific Outcomes

These interventions, practices, and disciplines are grouped together in this plan as mind and body* approaches because, from a research perspective, they all share a set of characteristics that create similar challenges in designing rigorous and definitive clinical investigations of their benefit and safety. For example, (1) it is generally difficult or impossible to mask practitioners and/or p...

A Study on Specific and Nonspecific Effects of Antisnake-Bite Serum

Nonhost resistance and nonspecific plant defenses.

In the past year, most of the advances in our understanding of nonhost resistance to plant pathogens have been incremental. Highlights include the discovery of a general bacterial elicitor of plant defenses, the description of more similarities between the hypersensitive response and animal programmed cell death, and a growing appreciation of the cell wall as the site of initiation and expressi...

Mononuclear Phagocytes (kupffer Cells) and Endothelial Cells

The fine structural characteristics and phagocytic properties of peroxidase-positive and peroxidase-negative cells in rat hepatic sinusoids were investigated. Cells with a positive peroxidase reaction in the endoplasmic reticulum and the nuclear envelope make up approximately 40% of cells in rat hepatic sinusoids and have abundant cytoplasm containing numerous granules and vacuoles, and occasio...

Specific and nonspecific resistance in mice immunized with irradiated Myobacterium leprae.

Following subcutaneous inoculation of irradiated Mycobacterium leprae (I-ML) into the left hind footpad of mice, there was increased resistance to Listeria monocytogenes, indicative of macrophage activation, at the immunization site. In spite of the high level of localized macrophage activation which was proportioned to the immunizing dose of I-ML, no such activity could be demonstrated systemi...
