(a.) Relating to, or resembling, porphyry, that is, characterized by the presence of distinct crystals, as of feldspar, quartz, or augite, in a relatively fine-grained base, often aphanitic or cryptocrystalline.
Example Sentences:
(1) Excretion of these metabolites was permanently elevated, but the values were comparatively low during cytotoxic therapy while peak values were recorded at the onset of fever during bone marrow aplasia; yet there were no clinical signs of porphyritic attacks at that time.
Porphyry
Definition:
(n.) A term used somewhat loosely to designate a rock consisting of a fine-grained base (usually feldspathic) through which crystals, as of feldspar or quartz, are disseminated. There are red, purple, and green varieties, which are highly esteemed as marbles.
Example Sentences:
(1) Sometimes fragments of the giant Reichschancellery, due to the recycling habits of East Germans, are seen: the walls and platforms of one U-Bahn station are inlaid with great lumps and plates of porphyry, fragments prised from the floors across whose glassy and obsessively waxed surfaces foreign dignitaries once had to pick their way into the Führer's presence.
(2) Histological changes caused by intratracheally introduced respirable mixed rock patterns (Porphyry, Enargite, Scarnic grained- and drill-cuttings) were examined and compared with standard DQ12 quartz samples 3, 6, 12 and 20 months after treatment.
(3) The biochemical diversity of the various porphyris often leads to incomplete investigation of photosensitive patients and porphyria may be excluded wrongly on the basis of normal urinary porphyrins alone.
(4) In spruce stands on quartz-porphyry sites raw humus is formed on strongly acid, calcium and phosphorus-deficient soils which were treated with lime, phosphate, and ammonium nitrate individually and in combined form.
(5) Next we are instructed to go to the Invalides and gaze down at Napoleon's Tomb, a squat mass of red porphyry which might have been more elegant had the British released the emperor's body from St Helena earlier in the 19th century.
(6) Due to the membrane-damaging effect of DQ 12 silica and mixed dusts (enargite and porphyry rock dusts) an increase in acid phosphatase activity of macrophages could be observed at the end of the first month.
(7) In the case of Porphyry rock patterns also storage type reaction developed.
(8) The influence of the nutrient status is clearly manifest in the humus form (raw humus in the case of quartz porphyry, mull-resembling moder in the case of basalt), but scarcely in the chemical and microbiological properties of the Of subhorizon.
(9) At this period, Afghanistan was the epicentre of classical globalisation: midway on the trade route from Rome to China, traders came to Afghanistan from all over the world, bringing painted glass from Antioch, inlaid gold vessels from Byzantium, porphyry from Upper Egypt, ivories from South India, carpets from Persia, horses from Mongolia and Siberia, and lacquers and silk from the China coast.
