Eradication of Acinetobacter baumannii by photosensitized agents in vitro

Journal of Photochemistry and Photobiology B: Biology, 1998
The photodynamic effects of photosensitizers on Acinetobacter baumannii were studied. These Gram negative bacteria have recently been implicated in various infections, mainly acquired in hospitals. They have outstanding characteristics of multidrug high resistance to antimicrobial agents. The best photodynamic effect was obtained when A.

Photosensitizers as virucidal agents.

Journal of photochemistry and photobiology. B, Biology, 1993
The photosensitizer, benzoporphyrin derivative monoacid ring A (BPD-MA) has been studied regarding its ability to destroy enveloped viruses in blood and blood products when activated by light. Its maximum wavelength of absorption (690 nm) has proven useful in terms of activation of the photosensitizer in materials containing red blood cells ...

SULFANILAMIDE: A PHOTOSENSITIZING AGENT OF THE SKIN

Journal of the American Medical Association, 1937
In spite of the intensive use of sulfanilamide in the last year as a chemotherapeutic agent in beta-hemolytic streptococcus infections, clinical reports have noted a relatively low incidence of untoward reactions. Our observations of more than 300 patients in the erysipelas wards of Bellevue Hospital (service of Dr.

Preclinical Evaluation Of Photosensitizing Agents

SPIE Proceedings, 1989
Methods for the pre-clinical evaluation of new photosensitizing dyes are described. The resulting information can provide useful leads concerning likely modes and sites of localization. But correlations between results obtained in cell culture and in animal tumor models are sufficiently weak to indicate the need for caution in extrapolation of any in ...

[Exogenous photosensitizing agents].

La Revue du praticien, 1992
The frequent use of remedies either in topical or systemic form has led to a rising number of photosensitizations. The different cutaneous manifestations of exogenous photosensitizers e.g. phototoxicity and photoallergy, are described. We treat the most important agents of these reactions and lay stress upon the patient's interview and the phototesting

A carbohydrate-linked hypericinic photosensitizing agent

Monatshefte für Chemie - Chemical Monthly, 2008
With respect to an enhanced solubility under physiological conditions, a carbohydrate-containing hypericin-based second-generation photosensitizer was prepared. Its photochemical properties were tested by means of the light-sensitized destruction of bilirubin IXα to be even better than those of the parent compound hypericin.

TREATMENT OF PSORIASIS WITH PHOTOSENSITIZING AGENTS

Archives of Dermatology and Syphilology, 1941
The sun's rays appear to be valuable in the treatment of psoriasis, and in most cases the condition improves during the summer months. In many cases of extensive lesions with indurated plaques and in cases in which the condition becomes aggravated rather than improved in the summer, it is possible that the skin is not photosensitive.

GABAergic agents as anticonvulsants in baboons with photosensitive epilepsy

Neuroscience Letters, 1984
GABAergic agents have been evaluated for acute anticonvulsant activity in baboons, Papio papio with photosensitive epilepsy. The potent GABAA agonists muscimol and THIP are proconvulsant. (-)Baclofen, 2 mg/kg suppresses myoclonic responses; higher doses facilitate EEG paroxysmal activity.

Porphyrins as Antimicrobial Photosensitizing Agents

2013
The emergence of microbial resistance to many of the major classes of antimicrobial drugs is becoming an increasing problem in the clinic and environmental areas. As such, the discovery of drugs with novel modes of action will be vital to meet the threats created by the emergence of resistance.
