The concept of chronic pathological processes.

The chronic pattern of lesions and the behaviour of each process as a whole, the internal relationships between sequences, the dynamics of factor assemblies determining the sequences and development of lesional chains, the propelling and cohesional factors are analysed in the morphopathogenic modalities of chronic processes, the chronic transformation of acute lesions and the primary chronic processes. This structural analysis lends support to the consideration of chronic pathological processes as systems and their investigation by the methods of the systemic conception applied to pathology. Key words: chronic pathological processes, chronic pattern of lesions, chronic transformation of acute lesions, primary chronic processes, sequential development, assemblies of factors, propelling factors, cohensional factors, proliferative dominance, self-perpetuation and auto-aggression mechanisms, stereotyping of chronic processes, systemic conception.
