An attempt was made to influence this isolated system pharmacologically. Previously, contradictory results have been published regarding the effects of parasympathomimetic and sympathomimetic drugs. We investigated the muscarinic agonist carbachol and the beta 2-adrenoreceptor stimulating drug clenbuterol. Carbachol (10(-3) M) did not modify the ciliary frequency in 6 experiments neither at 37 degrees C nor at 24 degrees C, where the basal frequency was reduced. Spiropent (10(-5) M), a pharmaceutical preparation of clenbuterol and lactose, increased the ciliary frequency in 3 experiments. Clenbuterol, tested in the same concentration in 1 experiment, also caused an increase. Lactose was without effect. The secretolytic drug ambroxol did not influence the ciliary frequency. The neuropeptide substance P which causes an increase in ciliary frequency in the respiratory tract of rabbits in vivo, had no effect on isolated human ciliated cells indicating an indirect effect of this peptide. Calcitonin gene-related peptide which co-exists with substance P in sensory neurons of the airways, increased the ciliary frequency in 1 out of 6 experiments. In conclusion, our results indicate that ciliary activity can be directly modified via beta 2-adrenoreceptors. Other putative neuronal mediators did not reveal clearcut direct activity.</p>","PeriodicalId":76098,"journal":{"name":"Laryngologie, Rhinologie, Otologie","volume":"67 10","pages":"518-22"},"PeriodicalIF":0.0,"publicationDate":"1988-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13615006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a light source we used an argon-ion-pumped-dye laser (630 nm wavelength), and for photosensitization we employed a mixture of dihematoporphyrinester and -ether (DHE). The photodynamic reaction on squamous carcinoma cells was proportional to the DHE concentration, the DHE incubation time, and the light exposure. Maximal tumor cell destruction in comparison to DHE free controls was observed with DHE concentrations of 5-10 micrograms/ml medium and a light exposure of 2-4 Joule/cm2.

To avoid floating tissue during washing and incubation the fresh frozen sections may also be slightly fixed by covering with gelatine or with a drop of acetone. Both techniques cause non-specific fluorescence. It is most advisable to dry the unfixed sections and to rinse them. Sections of stored renal, brain and inner ear tissue of the hamster also showed both a good preservation of the tissue structures and a perfect result of an antigen-antibody reaction. Relatively strong autofluorescence was found in the stria vascularis, the spiral ligament, the organ of Corti and in the basilar membrane. After incubation with normal serum, non-specific fluorescence was found in addition in the bone and in the tectorial membrane.
