    摘要: Carbamic acid lactones of the formula ##STR1## wherein Y is H or alkyl of 1-4 carbon atoms and R.sub.2 and R.sub.3 each are H or collectively with the carbon atoms to which they are attached form a first benzene or pyridine ring which is unsubstituted, substituted by up to two of alkyl, alkoxy of 1-4 carbon atoms, dialkylamino or halogen, wherein alkyl and alkoxy in each instance are of 1-4 carbon atoms, or is fused at two adjacent carbons to a second benzene or pyridine ring, are useful as intermediates for the production of penicillins by reaction with a penicillin of the formula ##STR2##

    摘要: System of implant components containing active agents, wherein each component is intended to function as an additive for an implant material produced with a powdery or finely granulated starting material and/or active agents and additives.Each component is powdery or finely granulated and includes at least one powdery or finely granulated active agent or additive having a higher dosage than the desired concentration for the application. The components themselves are made of a powdery or finely granulated starting material for the implant material, as well as of the active agent or additive. The active agents can be chemotherapeutical agents, such as antibiotics, whereas the additives can be x-ray contrast materials and/or or additives that alter the physical properties of the starting material, such as its elasticity or viscosity.
