When applied at the "ear" stage of growth of triticale, a fungicide is profitable on average for seven years experiments realised from 1985 to 1991 in Belgian loamy region. Nevertheless this profitability is not assured every year. In wet summer season a supplementary early treatment shows interest. In this case, the "flag leaf" stage must be prefered to the "1st - 2nd node" one. [less ▲]

The protection of creatine kinase MM sub-bands by EDTA during storage.

We examined the effect of a 5 mmol/l concentration of EDTA on the stabilization of the five serum creatine kinase MM isoenzymes, resolved by thin-layer isoelectric focusing. In patient sera, total CK and ... [more ▼]

We examined the effect of a 5 mmol/l concentration of EDTA on the stabilization of the five serum creatine kinase MM isoenzymes, resolved by thin-layer isoelectric focusing. In patient sera, total CK and CK-MB activities were stable during storage of the samples for two months at 4 degrees C even in the absence of EDTA. However, EDTA stabilized the labile MM and MM1 sub-bands, which are the first to appear in the blood after the release from the damaged tissue and its addition to blood samples intended for determining the MM sub-band pattern is recommended. The stabilizing effect of EDTA was emphasized at higher temperatures. EDTA protected the CK-MM pattern in myocardium extracts made in normal serum and incubated at 37 degrees C during 40 h, but was unnecessary when myocardium was homogenized in heat-inactivated serum. It is thought that EDTA could act by inhibiting a heat-labile component of human serum. [less ▲]

Protection of native chlorophyll(ide) forms ans of photosystem II against photodamage during early stages of chloroplast differentiation

in Acta Physiologiae Plantarum (1995), 17(2), 123-132

The resistance of chlorophyllide to intense light and the integration of chlorophyll to photosystems have been studied during the early stages of the greening process in etiolated bean or barley leaves. The possible role of NADPH-protochlorophyllide-oxidoreductase in chlorophyllide protection is discussed on the basis of chlorophyllide absorbance data during photodegradation and of chlorophyllide fluorescence lifetime measurements. Free chlorophyll during continuous greening was evaluated through fluorescence spectroscopy and fluorescence lifetime measurements in isolated etiochloroplasts. Its relative amount was maximum after 2 hours and decreased rapidly to a low level in parallel to photosystem II variable fluorescence development. Photosystem II mediated electron transport was compared in etiochloroplasts from flashed leaves before or after photoactivation of the water-splitting system. The effects of exogenous quinones on rapid fluorescence transients suggest the occurrence of a cyclic electron flow in water-splitting deficient photosystem II. [less ▲]

Protective activity of propofol, Diprivan and intralipid against active oxygen species.

We separately studied the antioxidant properties of propofol (PPF), Diprivan (the commercial form of PPF) and intralipid (IL) (the vehicle solution of PPF in Diprivan) on active oxygen species produced by phorbol myristate acetate (10(-6) M)-stimulated human polymorphonuclear leukocytes (PMN: 5 x 10(5) cells/assay), human endothelial cells (5 x 10(5) cells/assay) or cell-free systems (NaOCl or H2O2/peroxidase systems), using luminol (10(-4) M)-enhanced chemiluminescence (CL). We also studied the protective effects of Diprivan on endothelial cells submitted to an oxidant stress induced by H2O2/MPO system: cytotoxicity was assessed by the release of preincorporated 51Cr. Propofol inhibited the CL produced by stimulated PMN in a dose dependent manner (until 5 x 10(-5) M, a clinically relevant concentration), while Diprivan and IL were not dose-dependent inhibitors. The CL produced by endothelial cells was dose-dependently inhibited by Diprivan and PPF, and weakly by IL (not dose-dependent). In cell free systems, dose-dependent inhibitions were obtained for the three products with a lower effect for IL. Diprivan efficaciously protected endothelial cells submitted to an oxidant stress, while IL was ineffective. By HPLC, we demonstrated that PPF was not incorporated into the cells. The drug thus acted by scavenging the active oxygen species released in the extracellular medium. IL acted in the same manner, but was a less powerful antioxidant. [less ▲]
