Abstract: A subarachnoid pharmacodialysis apparatus insertable under the scalp, in and under the cranium, with a relatively short and simple neurosurgical procedure, to be kept there safely implanted for a year or longer for the purpose of regulating the neurochemistry of one or more diseased cerebral cortical areas and thus to achieve therapeutic effects via both localized delivery of medication and drainage of local neurotoxic molecules across the subdural meninges and compartments in a feedback-controlled fashion, with or without the additional capability of performing localized neurochemistry regulation in subcortical areas. This apparatus is also used for neurochemical profiling of the diseased brain area or areas by analyzing the removed endogenous molecules and adjusting the composition of the delivered medication based on the patient's specific, abnormal neurochemistry within the treated area or areas.

Abstract: A medically beneficial preparation is provided which contains amino acids and is applicable for augmenting the anti-viral and anti-inflammatory effects of interferon and thimidine-analogous antiherpetic drugs, for amelioration of psoriatic symptoms, and for treating Herpes virus infections.

Abstract: The invention relates to a process for the preparation of .alpha.- and .gamma.-interferon by isolating the buffy coat fraction of blood, removing the erythrocytes, suspending the leukocytes in a suitable nutrient medium and treating with an .alpha.-interferon inducer and with a .gamma.-interferon inducer, which comprises producing .alpha.-interferon and .gamma.-interferon one after the other in the same leukocyte culture by pre-treating the suspension obtained after the separation of the leukocyte/buffy coat/fraction of blood, removal of the erythrocytes and suspending the leukocytes in a suitable nutrient medium with - or .beta.-interferon, contacting with an .alpha.-interferon inducer, separating the liquid containing the .alpha.-interferon from the cells, if desired recovering the -interferon, washing and suspending the cells in a suitable nutrient medium, treating with a mitogenic agent, separating the liquid comprising .alpha.-interferon from the cells and if desired recovering .alpha.
