Draize Eye Irritancy Test Rabbits

Household products, shampoos, pesticides, weed killers, even riot control gases, are just some of the products tested for irritancy in the eyes of conscious rabbits. The Draize test, introduced in 1944, is cruelly simple. The substance under test is sprayed or instilled into one eye of an albino rabbit. Generally no pain relief is given and the test often proceeds for 7 days during which the co...

Irritancy of the skin disinfectant n-propanol.

Hand disinfection with short-chain aliphatic alcohols, so-called "rub-ins" is the method of choice for cross-infection prevention in health care environments, but their irritant potential is not well known. Skin tolerance is a major compliance factor, and a high proportion of health care workers suffer from low-grade irritant contact dermatitis. Therefore, assessment of the irritancy of the ski...

Testing Under Communication Constraints

The problem of fault diagnosis with communication constraints is considered. Most approaches to fault diagnosis have been focused on detecting and isolating a fault under cost constraints such as economic factors and computational time. But in some systems, such as remote monitoring (e.g., satellite, sensor field) systems, there is a communication constraint between the system being monitored a...

Vitrigel-eye irritancy test method using HCE-T cells.

We previously reported that the time-dependent relative changes of transepithelial electrical resistance (TEER) after exposing four different chemicals to a human corneal epithelium (HCE) model were well correlated to the potential of ocular irritancy. Meanwhile, we recently developed a collagen vitrigel membrane (CVM) chamber possessing a scaffold composed of high-density collagen fibrils equi...
