From an acid methanolic extract of about 7000 brains of the desert locust (Schistocerca gregaria) two novel neuropeptides, schistomyotropin-1 (Scg-MT-1) and schistomyotropin-2! (Scg-MT-2), were isolated and identified. Their primary structures are GAAPAAQFSPRLamide (Scg-MT-1) and TSSLFPHPRLamide (Scg-MT-2). Scg-MT-1 belongs to the locustamyotropin ...

The use of 5-aminolaevulinic acid (ALA) is gaining increasing attention for photosensitization in photodynamic therapy of superficially localized tumours. The aim of this work was to determine the kinetics of porphyrin generation in tissues after topical application of ALA delivered in different vehicles on the skin overlying the tumour and normal ...

Purpose. Many compounds are applied to the skin with the aim of targeting deeper underlying tissues. This work sought to define the pharmacokinetics of solutes in tissues below a topical application site in terms of perfusate binding, tissue binding and perfusate flow rate. Methods. The disposition kinetics of diclofenac in a single pass perfused l...

Some pharmacokinetic parameters of eprinomectin were determined in goats following topical application at a dose rate of 0.5 mg/kg. The plasma concentration versus time data for the drug were analysed using a one-compartment model. The maximum plasma concentration of 5.60±1.01 ng/ml occurred 2.55 days after administration. The area under the concen...

Some pharmacokinetic parameters of selamectin were determined in male (n = 5) and female (n = 5) Beagle dogs following a topical application at a dose rate of 6 mg/kg. The plasma concentration versus time data for the drug were analysed using a one-compartment model. The maximum plasma concentrations of 12.72±5.13 ng/ml for males and 22.65±11.95 ng...
Comparative insecticidal efficacy of metofluthrin, a newly synthesized pyrethroid, and other pyrethroids against several colonies of Asian Culex quinquefas-ciatus (from Indonesia, Thailand, Vietnam and Malaysia) was evaluated by topical application. Metofluthrin was the most effective against the four colonies of Cx. quinquefasciatus. The LD50-base...
Human skin prepared with an optical clearing agent manifests reduced scattering as a result of de-hydration and refractive index matching. This has potentially large effects for laser therapies of several skin lesions such as port wine stain, hair removal and tattoo removal. With most topically applied clearing agents the clearing effect is limited...
