Abstract: Neurological therapy devices are disclosed for the local and controlled delivery of a neurotransmitter to the brain of a subject suffering from neurotransmitter deficiency or dysfunction. In one embodiment the device includes a biocompatible, implantable, and retrievable polymeric insert including a source of neurotransmitter embedded therein. In another embodiment, the device includes a retrievable source of neurotransmitter including at least one neurotransmitter-secreting cell encapsulated within a semipermeable membrane allowing the diffusion therethrough of the neurotransmitter, and further includes a source of growth factor in close proximity to the neurotransmitter-secreting cells.
Abstract: A method for synthesizing camptothecin and camptothecin analogs using a novel hydroxyl-containing tricyclic intermediate and the camptothecin analogs produced by the process. The camptothecin analogs are effective inhibitors of topoisomerase I and show anti-leukemic and anti-tumor activity.
Abstract: A system for stabilizing fibroblast-derived growth factors, maintaining their bioactivity over a prolonged period of time and controllably releasing them for use is disclosed. The system uses growth factors bound to biocompatible substrates via heparin or heparin derived compounds to maintain the bioactivity of the growth factors. A growth factor bound to a heparin coated substrate can be used independently as a controlled release device, or can be incorporated into a reservoir or matrix type controlled release devices to further enhance the controlled release properties. The stabilized growth factors can be implanted into a patient, thereby providing a means for producing an in vivo controlled release of a growth factor to the patient.

Abstract: Heterocyclic compounds of the general formula: ##STR1## wherein R.sup.11 is a hydroxyl group or a lower alkoxy group, R.sup.12 is a lower alkoxy group, R.sup.13 is a saturated or unsaturated hydrocarbon group, X is an oxygen atom or a sulfur atom, and Y is an oxygen atom or --NH-- which may have a lower alkyl substituent, or salts thereof are novel and effective in controlling carcinoma.
Abstract: Water-insoluble drugs are rendered injectable by formulation as aqueous suspensions of phospholipid-coated microcrystals. The crystalline drug is reduced to 50 nm to 10 .mu.m dimensions by sonication or other processes inducing high shear in the presence of phospholipid or other membrane-forming amphipathic lipid. The membrane-forming lipid stabilizes the microcrystal by both hydrophobic and hydrophilic interactions, coating and enveloping it and thus protecting it from coalescence, and rendering the drug substance in solid form less irritating to tissue. Additional protection against coalescence is obtained by a secondary coating by additional membrane-forming lipid in vesicular form associated with and surrounding but not enveloping the lipid-encapsulated drug particles. Tissue-compatible formulations containing drug in concentrations up to 40% (w/v) are described.
Abstract: An embalming fluid. A chemical composition comprising chemicals that are, generally, non-hazardous to humans in the concentrations used. Also, specimens preserved in the composition look and feel more life-like than specimens preserved in formaldehyde based compositions.
