title: Application of Corynebacterium parvum lysate into the brain of rats--morphological study.
abstract: The authors investigated the influence of application of the Corynebacterium parvum lysate (CPL) into the brain of rats with aim to define the resulting morphological changes. Variable amount of the CPL (0.1, 0.35, 0.7 mg) was injected under stereotactic control into frontal lobe of the left cerebral hemisphere. Morphological changes were studied after intervals of 3, 7, 14, and 30 days respectively. CPL lead to inflammatory and reparative changes in direct relations to the administered dosage. The most pronounced reaction was observed on days 3 and 7. Morphological changes were still visible on day 14. There were no valid difference between the application of efficient CPL and the control physiological saline solution (PSS) after thirty days. The authors suggested that CPL is likely to be safe also in human malignant brain tumor therapy.
