EPILOGUE The dilemma of modern medicine W. Watson Buchanan 347 Index 351 INFLAMMOPHARMACOLOGY Basic and clinical studies on inflammation and its pharmacological control Alms and Scope The journal Inffammopharmacology publishes papers on ail aspects of inflammation and its pharmacological control, emphasizing comparisons of (a) different inflammatory states, and (b) the actions, therapeutic efficacy and safety of drugs employed in the treatment of inflammatory conditions. The comparative aspects of the types of inflammatory conditions include gastrointestinal disease (e.g. ulcerative colitis, Crohn's disease), parasitic diseases, toxicological manifestations of the effects of drugs and environmental agents, and arthritic conditions. Inflammopharmacology covers all the major aspects of the experimentally-induced clinical pathology, its biochemistry and cell biology, as well as the clinical and experimental pharmacology and toxicology of therapeutic agents. The emphasis on comparative aspects of the actions of drugs is intended to highlight their efficacy and toxicity profiles as well as the variability in their clinical response and safety. ISSN 0925-4692 In summary the journal covers: • Experimental development of in vitro systems and in vivo animal models • Assay methodologies • Biochemical, immunological and pharmacological studies • Clinical pharmacology and therapeutics • Drug-induced side-effects - their incidence and mechanisms • Comparative drug studies and trials • Novel approaches towards the therapy of inflammatory conditions, including brief but carefully conducted reports on therapies with as yet undefined materials (e.g. natural products, immunological agents) which may be considered as giving leads or encouragement to others to further purify or define the active ingredients and explore their actions. The journal publishes peer-reviewed unsolicited papers, reviews, short commu nications, letters to the editor, drug status reports, editorials and short summaries of hypotheses, and supplements.
