Histological changes in the pancreas of white rats after administering cephalexin and ethanol.

The research was conducted on male Wistar rats weighing approximately 200 g. Animals of experimental group I were administered 20% ethyl alcohol for drinking, animals of experimental group II--cephalexin in the dose of 42 mg daily, animals of experimental group III--simultaneously alcohol and cephalexin in the mentioned doses.
