Abstract: Racemic 1-(4-methoxybenzyl)-1,2,3,4,5,6,7,8-octahydroisoquinoline can be resolved by seeding the supersaturated solution of racemic 1-(4-methoxybenzyl)-octahydroisoquinolinium acetate with its enantiomeric forms and crystallizing the optically active acetate corresponding to the configuration of the seed crystals. The continuous form of the process permits obtaining the two enantiomers together.

Abstract: There is provided a novel drug delivery system which provides for intermittent drug delivery with readily adjustable intervals between drug delivery pulses. This is accomplished by providing a multilayer device in which layers of active drug are readily expandable or erodable when contacted with the environment in which the drug is to be administered. The drug layer is alternated with an inert layer and a multiplicity of such layers are contained within a tube impervious to such environment but provided with an opening into such environment. The multiplicity of such layers is driven along the length of such tube towards the opening. The interval between pulses is determined by the rate the layers are driven along the tube and the sizes of the layers. The duration of the pulse is determined by the rate of expansion or dispersion of the active layer into the environment, wherein the rate of expansion or dispersion is greater than the rate the layers are driven along the tube.

Abstract: High levels of immunity are achieved in chickens inoculated intramuscularly or orally with E. acervulina extract immunogens. These extracts contain at least 20 polypeptides which induce a protective immune response not only against E. acervulina but also against E. tenella and E. maxima. The resulting immunity prevents intestinal lesions and reduces the number of viable oocysts in vaccinated and challenged birds. One or more of these polypeptides can be used as an immunogen to protect against coccidiosis.

Abstract: N-substituted fused-heterocyclic carboxamide derivatives, for example, N-(2,2-diphenylethenyl)-3-hydroxythieno[3,2-b]thiophene-2-carboxamide can be prepared by ring closure between an appropriately substituted halo-thiophene ester, e.g., methyl 3-bromo-thiophene-2-carboxylate, and mercaptoacetamide followed by condensation with diphenylacetaldehyde. Alternatively, the ring closure can be carried out between an appropriately substituted mercaptothiophene ester, e.g., methyl 3-mercaptothiophene-2-carboxylate and a haloacetamide to afford the fused-heterocyclic intermediate, 3-hydroxythieno[3,2-b]thiophene-2-carboxamide. N-alkenylation of the intermediate will then lead to the final products.
