Toxicology and Teratology Research with ALZET Pumps
When assessing risk, an understanding of the involved toxicologic mechanisms can be helpful. Areas of recent interest include research on the interplay between immunology and toxicology, the neurotoxicity of a variety of compounds, and research on the process of apoptosis. Controlled, continuous delivery of test agents using ALZET osmotic pumps has proven useful in these areas of research.
Examples of recent work
in these and related areas are included in a general
list of references on toxicology research. Cell proliferation
labeling affords insight into the potential carcinogenesis resulting
from exposure to toxic agents. A well proven and reliable technique
involves the continuous infusion of bromodeoxyuridine. Continuous
exposure to the labeling agent is likely to capture a summation of
cell proliferation activity over several days, and can reduce the
likelihood of overlooking bursts of proliferation.
The ability to infuse agents continuously to pregnant animals can provide insight into a myriad of teratologic effects. ALZET pumps have been used to infuse valproic acid, drugs of abuse, and a variety of agents under teratologic investigation.
A list of references is available on teratology research. A wealth of information regarding the use of ALZET osmotic pumps in toxicology and teratology research can be found in this bibliography* section.

*Some of these bibliographies may be large and take a short while to display. These bibliographies are updated frequently. As the references are listed most recent first, you may wish to truncate your printing to ten pages or less.
Since 1977, scientist around the world have used ALZET pumps to conduct their research, publishing their results in high-impact journals. The ALZET bibliography now contains over 16,000 publications! We can perform a custom search for references relevant to your research.
What researchers are saying...
“Nicotine was chronically administered subcutaneously to rats via osmotic mini-pumps. This model was proved to be a convenient and efficacious alternative to multiple injections to mimic the chronic intake of smokers.” Cormier et al., Neuropharmacology 2003;44:642-652.
