Influenza and pneumococcal vaccinations in dialysis patients in a London district general hospital.

Background: Patients on dialysis mount reduced immune responses compared with the general population. The Department of Health advises that these patients receive influenza and pneumococcal vaccinations at regular intervals-once yearly and every five years, respectively. This article investigates the uptake of these vaccinations in this patient population and seeks to examine factors that may influence vaccination status such as patient's language and presence of a general practitioner (GP) electronic vaccination reminder system.

Variations in lipophilic and vacuolar flavonoids among European Pulicaria species.

Four European Pulicaria species, P. odora, P. paludosa, P.

Identification of lipophilic flavones and flavonols by comparative HPLC, TLC and UV spectral analysis.

The identification of lipophilic flavones and flavonols using a combination of high performance liquid chromatography, thin layer chromatography and UV spectral analysis is discussed. Data are provided for the flavones, apigenin, luteolin and tricetin and twelve of their methyl ethers, 8-hydroxyluteolin, 6-hydroxyluteolin and scutellarein and fourteen of their methyl ethers, and some 6,8-dihydroxyapigenin and 6,8-dihydroxyluteolin derivatives. Data for some forty two flavonols with extra 6- and/or 8-hydroxylation, mostly 6-hydroxykaempferol and quercetagetin derivatives, are also presented.

Acacetin glycosides as taxonomic markers in Calamintha and Micromeria.

A new acetylated flavone glycoside, acacetin 7-O-[6""-O-acetylglucosyl(1""-->2")]rhamnosyl(1"'-->6")glucoside, has been isolated from the leaves of Calamintha glandulosa together with the known compound acacetin 7-O-rhamnosyl(1"'-->6")glucoside. The occurrence of these flavonoids in the closely related genera Satureja, Micromeria, Acinos and Clinopodium indicates that their distribution may be of taxonomic significance.
