Television programming covering disability over a ten year span, 1967-68 and 1977-78, was studied to determine similarities and differences. Variables identified for comparisons included network, program type, disability, time slot, and length of programming. The largest frequency of programs occurred on NBC in 1968. However, in 1978 the largest frequency occurred on the Public Broadcasting System. This can be partially explained by the increased numbers of programs on PBS overall and their traditional concern with public interest and service programming. The commercial networks historically have been in the business of entertaining and portray disability more so in that fashion. Movies head the list in 1968. However, in 1978, dramatic series and children's programming head the list followed by news documentaries and telethon. Paraplegia was the most frequent disability portrayed in 1968 followed by mental illness, drug addiction and emotional disability. In 1978 mental illness headed the list followed by alcoholism, emotional disability and physically handicapped. Paraplegia in 1968 can be accounted for by the program "Ironside" that featured a paraplegic detective. Mental illness and emotional disturbance seem to be consistent targets over the decade for popular programming in prime time.

Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic pathogen that can be found in individuals in which the immune system has been suppressed by HIV/AIDS or chronic alcoholism. We evaluated the role of inducible nitric oxide synthase (NOS II) as a modulator of lung concentrations of P. aeruginosa in normal rats and rats given a single dose of ethanol (ETOH). Rats were pretreated with either sterile saline (PBS, 0.1 ml/kg, i.v.) or the NOS II inhibitor L-N6-iminoethyl lysine (LNIL, 10 mg/kg, i.v.) 15 min before intraperitoneal administration of either PBS (4.5 ml/kg) or ETOH (4.5 g/kg). Thirty min after administration of PBS or ETOH the rats were placed in inhalation chambers and exposed to 45 min of an aerosol containing P. aeruginosa (5 x 10(4) colony forming units, CFU). A group of rats (n = 5-6/treatment/time period) were killed immediately (0 hr) or 4 hr after inhalation of P. aeruginosa. The lungs were homogenized and the P. aeruginosa were grown in nutrient broth to determine the number of viable CFU remaining in the lung. The NOS II and TNFalpha mRNA and protein content lung alveolar macrophages (AM) and neutrophils (PMN) were measured with RT-PCR and Western blot. The concentration of nitrate and nitrite anion in the bronchoalveolar lavage fluid (BALf) and ex vivo incubates of PMN were also measured. The CFU of P. aeruginosa present in the lungs of the four groups of rats at 0 hr did not differ. The CFU of P. aeruginosa in the lung increased (p < 0.05) in rats pretreated with ETOH when compared with that obtained from rats pretreated with PBS. However, pretreatment of rats with LNIL decreased (p < 0.05) the 4 hr lung content of P. aeruginosa. Coadministration of LNIL and ETOH to rats augmented the CFU of P. aeruginosa in lungs to amounts which did not differ from that of rats pretreated with ETOH. Inhalation of P. aeruginosa increased NOS II mRNA and protein in rat AM and PMN. Pretreatment of rats with ETOH alone, or in combination with LNIL, inhibited P. aeruginosa-induced NOS II transcription and translation and AM and PMN nitrate and nitrite generation whereas pretreatment with LNIL alone only inhibited nitrate and nitrite generation. Pretreatment of rats with ETOH suppressed P. aeruginosa stimulated PMN recruitment into the lung whereas LNIL enhanced (p < 0.05) P. aeruginosa-stimulated PMN recruitment into the lung. ETOH-induced increases of the lung content of P. aeruginosa were associated with increased PKC delta isozyme in the membrane of the PMN but could not be explained by altered plasma concentrations of hydrocortisone or ETOH. The data demonstrate that selective inhibition of NOS II-derived NO by LNIL decreases the lung content of P. aeruginosa whereas ETOH inhibits the lung clearance of P. aeruginosa. Speculatively, the difference between these effects of LNIL and ETOH may result from differences in drug-induced changes in lung recruitment of PMN.
