The murine local lymph node assay (LLNA) is an in vivo test for skin sensitisation.. LLNA has largely superseded the guinea pig maximisation test and the Buehler test.It is considered more scientific and less cruel (lower number of animals; less suffering) and has found broad scientific and regulatory acceptance.
The induction phase includes exposing a test group of animals twice to the test material, first by intradermal injection followed by topical application seven days later. During Induction A, the test animals are exposed intradermally to the test material, along with an adjuvant to enhance the immune reaction of the guinea pig. During Induction ...
A subject of the Tuskegee syphilis experiment has his blood drawn, c. 1953.. Numerous experiments which were performed on human test subjects in the United States in the past are now considered to have been unethical, because they were performed without the knowledge or informed consent of the test subjects.

The Buehler test is an in vivo test to screen for substances that cause human skin sensitisation (i.e. allergens). It was first proposed by Edwin Vernon Buehler in 1965 [1] and further explained in 1980. [2] It is a non-adjuvant test. In the test, guinea pigs are exposed to a high dose of the substance.
Human subject research is systematic, scientific investigation that can be either interventional (a "trial") or observational (no "test article") and involves human beings as research subjects, commonly known as test subjects. Human subject research can be either medical (clinical) research or non-medical (e.g., social science) research. [1]
From the common American guinea pig to the exotic Lunkarya Guinea Pig, these are the guinea pig breeds you should know about.
Currently, rodents are commonly used in animal testing for physiological, pathological and behavioral scientific studies, particularly mice and rats, but also guinea pigs, hamsters, gerbils and others. Mice are the most commonly used vertebrate species, due to their availability, size, low cost, ease of handling, and fast reproduction rate
