Channel catfish, Ictalurus punctatus, leukocytes secrete immunoreactive adrenal corticotropin hormone (ACTH)
The interrelationships between the neuroendocrine and immune systems are becoming more understood, at least in mammalian systems. The most characterized of these relationships is that of hormonalExpand

The Inhibition of Apoptosis in EL4 Lymphoma Cells Overexpressing Growth Hormone
The antiapoptotic action of exogenous growth hormone (GH) has been reported for several lymphoid cell lines; however, the potential role of endogenous GH in apoptosis has not been thoroughlyExpand

Effects of dietary PCBs and nonyl-phenol on immune function and CYP1A activity in channel catfish, Ictalurus punctatus
Abstract Polychlorinated biphenyls (PCBs) induce CYP1A, modulate immune responses, and may have endocrine disruption properties. Many coastal ecosystems and their tributaries contaminated with PCBsExpand

The Inhibition of Superoxide Production in EL4 Lymphoma Cells Overexpressing Growth Hormone
A substantial body of research exists to support the production of growth hormone by cells of the immune system. However, the function and mechanism of action of lymphocyte-derived growth hormoneExpand

Expression of insulin-like growth factor-1 and insulin-like growth factor-1 receptors in EL4 lymphoma cells overexpressing growth hormone.
Almost all of the previous studies with growth hormone (GH) have been done with exogenously supplied GH and, therefore, involve actions of the hormone through its receptor. However, the actions ofExpand

The production of nitric oxide in EL4 lymphoma cells overexpressing growth hormone
Growth hormone (GH) is produced by immunocompetent cells and has been implicated in the regulation of a multiplicity of functions in the immune system involved in growth and activation. However, theExpand

Public understanding of science in South Africa - aiming for better intervention strategies : science education
Nationally representative surveys to gauge the public understanding of science and attitudes towards science and technology have been undertaken in many developed countries. In March 1999, a Expand

Infantile hypertrophic pyloric stenosis: profile, management and outcome of patients admitted to a tertiary hospital in Bloemfontein, South Africa.
BACKGROUND Infantile hypertrophic pyloric stenosis (IHPS) is the thickening of both muscle layers of the pylorus and is most commonly found in first-born males. It usually presents with projectile,Expand
