 Title    Photosensibilisierung isolierter Mesophyllzellen von Calystegia sepium L. Photosensibilization o f Isolated Mesophyll Cells of Calystegia sepium L  
 Abstract    Cell division of isolated mesophyll cells o f Calystegia sepium can be made sensitive to long-wave UV (LUV) by treatment with 8-methoxypsoralen (8-MP). The inhibition o f cell division de­ pends on 8-MP concentration and the length o f light exposure. Only the simultaneous presence of 8-MP and LUV gives effective photosensibilization. Cells treated with 8-MP in the dark can be made non-sensitive to LUV by washing out the furocoumarin prior to irradiation. The furocou­ marins may offer a means o f cell selection.

 Title    Dark and Photohemolysis of Erythrocytes by Furocoumarins  
 Abstract    It has been shown that various furocoumarins are able to cause dark hemolysis in red blood cells (RBC). However, this effect is evident only at relatively high furocoumarin concentrations (4.6 x 10~ 4 M) -much higher than those used in photosensitization experiments or photo-chemotherapeutic treatments. Among the various furocoumarins examined in this study, only psoralen (Ps) and 3-carbethoxy-psoralen (3-CPs) showed strong photohemolytic effects, while the other compounds revealed little or no activity. This fact indicates that Ps and 3-CPs are able to induce selective damage to the cell membrane of RBC. By pre-irradiating furocoumarin in ethanol or isotonic saline solutions and adding the irradiated solutions to a RBC suspension, hemolysis was observed in various compounds. The products of photolysis which form during pre-irradiation may be responsible, in terms of hemolysis, for toxic effects on RBC.

 Title    Inhibition of cAMP Phosphodiesterase by Some Phototherapeutic Agents  
 Abstract    The behaviour of cyclic-3',5'-AMP phosphodiesterase has been studied in the presence of psoralen, 8-methoxy-psoralen (8-MOP), 4,5',8-trimethylpsoralen (TMP) (usu­ ally used in PUVA therapy), 4.6,4'-trimethylangelicin (TM A) and khellin recently proposed for the same thera­ peutical use. TMP and TMA exhibit a significant inhibitory effect on cyclic AMP phosphodiesterase; a light inhibition is produced by khellin at rather high concentration.
