(3-Lysin is the name that Pettersson proposed to distinguish this thermostabile bactericidal component of serum from Buchner's alexin or a-lysin (51). He defined (8-lysin as the bactericidal substance found in normal serum that resisted inactivation when heated to 56°C for 30 min. According to this definition, there are at least three different ,3-lysins found in normal serum; these consist of lysozyme, ,B-lysin from platelets, and (8-lysin of nonplatelet origin. The first of these, lysozyme, is a single entity which is well defined in regard to its chemical and biological properties. The other two types of (3lysins are not readily distinguished from each other, and each could be composed of several distinct molecules. The ,B-lysin of platelet origin may be similar or identical to plakin (23). The (8-lysin of nonplatelet origin may include the bactericidal cationic proteins isolated from leukocyte lysosomes (64-66). In this review, attention will be focused on the (3-lysin of platelet origin, which will be referred to as "platelet (3lysin."

Attention is drawn to the long-term effects of atmospheric contaminants in general (and cigarette smoke in particular) on immunological control mechanisms that are accepted as playing a vital role in the maintenance of health. The review argues that a hostile environment within the respiratory tract created by inhalation of air contaminants compromises local immunological function in the short term, and ultimately depresses systemic immunological function. Whether such a decline in immunological homeostasis is due directly to toxicity, or indirectly to accelerated aging of susceptible elements of the immune system, is speculative. The changes observed in both man and experimental animals exposed for long periods to air contaminants in many respects parallel those associated with normal aging and may represent an acceleration of the process of senescence. Specific biological effects of smoking, air pollution and immune functions in man and animal models are reviewed. The precise mechanism(s) by which air contaminants affect immunological function remains speculative, but the relative resistance of specified-pathogen-free animals to these agents infers a central role for the hosts' normal bacterial flora in the process.
