 Title    New Botrydial Sesquiterpenoids from Hymenoscyphus epiphyllus  
 Abstract    Four new botrydial derivatives, hymendial (1), 7a-hydroxydihydrobotrydial (2), 701-hy­ droxy-10-0-methyldihydrobotrydial (4), and 7a-acetoxy-15a-methoxy-10-0-methyl-dihydro-botrydial (5) were isolated together with dihydrobotrydial (3) from the culture fluid of the ascomycete Hymenoscyphus epiphyllus. In addition, cytochalasin H (6a), 18-deoxycytocha-lasin H (6b) and (+)-mellein (7) were produced by this fungus. Hymendial (1), possessing an a, ß-unsaturated dialdehyde functionality, exhibits antimicrobial and cytotoxic activities and is mutagenic in the Ames Salmonella assay.

 Title    Preliminary Report on the Effects of Propolis on Wound Healing in the Dental Pulp  
 Abstract    The purpose of this investigation was to determ ine the antimicrobial and healing potential of propolis on direct dental pulp exposures. This study used 25 adult male rats. Pulp expo­ sures were perform ed and animals were allocated to propolis and calcium hydroxide (C a(O H) 2 groups. Animals were killed on days 5, 7, 10, and 14. The teeth were routinely processed for histological evaluation. N on-param etric tests were employed to analyze the data. No significant differences were found between study groups on the wound healing of the dental pulp. Both substances were com parable in exhibiting normal reorganization of the pulp and no increased vascularity, and were equally efficacious in maintaining a low inflam­ matory and microbial cell population as well as in stimulating the formation of reparative dentin.

 Title    Eleftherios  
 Abstract    The antimicrobial activity of fifteen semisynthetic labdane-type diterpenes derived from the two major natural compounds 3 and 4 of the resin "ladano" of Cistus creticus is reported. The chloroethyl carbamidic esters 15 and 20 showed the strongest antimicrobial activity against Gram (+), Gram (-) bacteria and pathogenic fungi.
