Compositions and methods, including novel homogeneous microparticulate suspensions, are described for treating acute wounds, chronic wounds and/or a wound or epithelial tissue surface that contains bacterial biofilm, including unexpected synergy between bismuth-thiol (BT) compounds and certain antibiotics, to provide topical formulations including antiseptic formulations, for management and promotion of wound healing and in particular infected wounds. Previously unpredicted antibacterial properties and anti-biofilm properties of disclosed BT compounds and BT compound-plus-antibiotic combinations are also described, including preferential efficacies of certain such compositions for treating gram-positive bacterial infections, and distinct preferential efficacies of certain such compositions for treating gram-negative bacterial infections.

The present disclosure is directed to a method of treating a neuropsychiatric disorder. This method involves selecting a subject having the neuropsychiatric disorder and administering to the selected subject a preparation of glial progenitor cells at a dosage effective to treat the neuropsychiatric disorder in the subject. Another aspect of the disclosure is directed to a method of treating a neuropsychiatric disorder that includes selecting a subject having the neuropsychiatric disorder and administering, to the selected subject, a potassium (K.sup.+) channel activator at a dosage effective to restore normal brain interstitial glial K.sup.+ levels in the selected subject and treat the neuropsychiatric disorder is also disclosed.

Prooxidative chain-transfer agents for use in the treatment of a malignant tumour disease, or infectious disease. The prooxidative chain-transfer agents are selected from lipophilic thiols, lipophilic trithiocarbonates, lipophilic, aromatic dithioesters, and lipophilic, aromatic thiols. The compounds amplify the prooxidative activity at the target site and are therefore highly efficient and specific for their targets.
