A screening method was applied to determine the eye irritation potential of industrial chemicals. Bovine eyes (BE) were used to predict corneal damage and chicken egg chorioallantoic membranes (CAM) to estimate the irritancy potential of chemical sub

A method is described to investigate the induction of micronuclei in cultured human keratinocytes after short-term exposure to known clastogenic agents. The cytokinesis-block method was applied to facilitate the scoring of micronucleated cells. Mitom

Micronucleus formation in cultured human keratinocytes was studied after exposure to benzo[a]pyrene, cyclophosphamide and 12-O-tetradecanoylphorbol-13-acetate without the addition of an exogenous metabolizing system. The first two agents need bioacti

We used specific monoclonal antibodies (MAb) to human cytochrome P450 isoenzymes to determine the presence of these proteins in human epidermal cells. Two MAb (P450-5 and P450-8) recognize major forms of hepatic cytochrome P450 involved in biotransfo

A new method is described to investigate unscheduled DNA synthesis (UDS) in human tissue after exposure in vitro: the human hair follicle. A histological technique was applied to assess cytotoxicity and UDS in the same hair follicle cells. UDS induct

The morphology of human scalp hair follicle keratinocytes, cultured on the bovine eye lens capsule, is studied by light and electron microscopy. The hair follicle keratinocytes in the stratified cultures are characterized by the presence of numerous

For the first time a method for culturing human hair follicle cells is described. The bovine eye lens capsule, a basement membrane-like structure, is used as the substrate for the cultures. In a culture medium supplemented with hydrocortisone and ins
