Abstract

Goal of in-service NDT carried out in engineering plants is to reduce operational risk via contribution to insurance of the components’ structural integrity. NDT in structural integrity assessment has two directions. One of the basic problems in reliability assessment of engineering components having crack like flaws is on how the crack sensitivity of the component can be defined in terms of characteristic numbers. If we would be able to define it than the hazard of different flaws could be compared by pure numbers. The definition and introduction of a Crack Propagation Sensitivity Index of a component has fundamental meaning because the experimental results of the NDT, the loading conditions and the crack propagation resistance are physically connected by applying fracture mechanics principles in the components reliability assessment.

Hypoxis (Hypoxidaceae) consists of about 90 species of plants reported worldwide, of which 76 occur in Africa. As many as 41 species are indigenous to countries belonging to the Southern African Development Community (SADC), including South Africa. Of all the Hypoxis species, Hypoxis hemerocallidea has versatile application in traditional health care system of over 85% of South Africans and is regarded as one of the most ethnomedicinally important and most marketed species in South Africa. H. hemerocallidea corm’s water or alcoholic extract is widely used as traditional medicine for the treatment of benign hypertrophy and urinary tract infections as well as for boosting the immune system of people living with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) among others. However, the use of other parts of Hypoxis plant as medicine is vital for conservation purposes. The roots attached on the corm of H. hemerocallidea contain hypoxoside, but the roots are usually ripped off during the preparation of Hypoxis-containing traditional medicines and other herbal products. A developed and validated, affordable but reliable high-performance thin-layer chromatography (HPTLC) densitometry for the rapid and repeatable visualization and quantitative determination of hypoxoside from the roots of H. hemerocallidea was performed. After thin-layer chromatography analysis, the hypoxoside resolved and was visualized at R F of 0.30 in CHCl3‒MeOH‒H20 (70:30:2 v/v). The method was linear with R2 of 0.9876 over a calibration range of 0.20 × 10−4–1.80 × 10−3 mg mL−1. The limits of detection (LOD) and quantification (LOQ) were 5.08 × 10−4 and 1.65 × 10−3 mg mL−1, respectively, while the percentage recovery and the method repeatability (%RSD) were 84.10 and 4.98, respectively. The roots of H. hemerocallidea were found to contain 4.101 × 10−4 mg mL−1 of hypoxoside.

Bevezetés: Az osteoporosis fő következménye a csonttörés. A csonttörés esélyét a csont mennyiségén kívül számos tényező befolyásolja. A kockázati tényezők egy csoportja egyszerű kérdőívekkel vizsgálható. Célkitűzés: A jelen vizsgálat (Score-HU) célja volt, hogy felmérje az osteoporosisban szenvedő, oszteológiai szakrendelésre irányított postmenopausás nőknél (n = 11 221) az ismert kockázati tényezők előfordulási gyakoriságát. Módszer: A kockázati tényezőket minden beteg esetében egyszerű kérdőív segítségével rögzítették. Eredmények: A csonttörés legfontosabb kockázati tényezői gyakorisági sorrendben a következők voltak: korábbi csonttörés (79,4%), nem antiporotikus gyógyszerek szedése (vérnyomáscsökkentők 67,9%, altatók 36%, antidepresszánsok 26,5%, kortikoszteroidok 13,5%), mozgásképesség csökkenése (44,6%), korai menopausa (31,9%), dohányzás (31,2%), gyakori elesés (29,1%), rossz egészségi állapot (legalább 3 krónikus betegség előfordulása 24,1%). Következtetések: Az említett kockázati tényezők egyszerű klinikai felmérése alapján az osteoporoticus betegek csonttörési kockázatát pontosabban adhatjuk meg, mint ha csupán az oszteodenzitometriás mérési eredményre hagyatkozunk a törési kockázatbecslés során.
