What's the difference between ambrosia and ambrosin?
Ambrosia
Definition:
(n.) The fabled food of the gods (as nectar was their drink), which conferred immortality upon those who partook of it.
(n.) An unguent of the gods.
(n.) A perfumed unguent, salve, or draught; something very pleasing to the taste or smell.
(n.) Formerly, a kind of fragrant plant; now (Bot.), a genus of plants, including some coarse and worthless weeds, called ragweed, hogweed, etc.
Example Sentences:
(1) All patients were found to be sensitive to Ambrosia.
(2) The acute and subchronic toxicity of the molluscicidal plant, Ambrosia maritima L., has been tested on rats.
(3) A new species of the genus Zygozyma, Z. smithiae, was recovered from frass of the ambrosia beetle, Crossotarsus externedentatus in Northern Natal.
(4) Four hundred children were skin tested with following allergens: Dermatophagoides pteronyssinus, moulds, animal dander (mixture of dog, cat, sheep and horse dander), tree pollens, weed pollen (Ambrosia artemisifolia), and six grass pollens, as well as three nutritive allergens in children less than three years of age.
(5) Comparison of pollen capture with meteorologic data demonstrated that photoperiodic responses probably account for the initiation and termination of Ambrosia flowering, and to some extent that of Parthenium, and not sharply lowered temperatures or frost for ending pollen release.
(6) Skin tests with Ambrosia allergen extracts showed a positive rate of 67.7% in 624 cases of pollinosis.
(7) The total allergenicity of a pollen extract Ambrosia elatior was measured by quantitative prick test applied to the skin of seven highly sensitive patients and by standardized method of RAST-inhibition.
(8) The animals were placed in a cell in which an allergen-water-dialyzed extract of ambrosia pollen was dispersed by means of coaxial pulveriser.
(9) Anthemis cotula (dog fennel) and Xanthium strumarium (cocklebur) gave the most frequent positive results, demonstrating a change of frequency in sensitivity compared to the 1950s, when Ambrosia artemisiifolia (ragweed) was recognized as the most frequently sensitizing weed.
(10) This study analyzes Amb a I, a family of related proteins formerly known as Ag E, that comprise the major allergens of short ragweed (Ambrosia artemisiifolia).
(11) Since both Parthenium and Ambrosia are significant allergenic plants, correlations between airborne pollen of Parthenium and allergic potential suggest that a prolonged pollination season and perhaps increased allergenicity of unique Parthenium pollen proteins allow Parthenium to be a major allergen despite significantly less ambient pollen.
(12) Capture of native Ambrosia species and P. hysterophorus peaked in September and October in 1987 and 1988, but Parthenium pollen was also found year round with a smaller secondary peak during May, 1988 and 1989.
(13) The cloning of the AmbtV cDNA is important, since the 4.4-kDa AmbtV, one of the allergens in giant ragweed (Ambrosia trifida) pollen, serves as a simple model system to study the basic structural requirements for immune recognition of foreign protein allergens.
(14) Mean radionuclide levels in cattle tissue and environmental samples from Ambrosia Lake were higher in almost every comparison than those found in respective controls.
(15) Seeds of the short ragweed (Ambrosia artemisiifolia) were collected from 38 different sites in Champaign County, Ill. Plants from these seeds were grown under similar conditions, and antigen E (AgE) was determined on pollen samples harvested from individual plants.
(16) Mowing or hand weeding cannot eradicate Ambrosia artemisiifolia but if they are consistently used, they could reduce its population level over several years by decreasing seed production.
(17) These spectra were very close to those of the polysaccharides from the C. clavata and C. ambrosia groups of Ceratocystis species.
(18) Previous studies have associated skin test sensitivity and specific IgE response to Ambrosia artemisiifolia V (Amb a V) with HLA-DR2, and to Ambrosia trifida V (Amb t V) with HLA-DRw52 haplotypes in atopic individuals.
(19) Ambrosia Lake, New Mexico, has been the site of extensive U mining for 30 y and contains several underground U mines, a processing mill, and two large U tailings piles.
(20) Positive patch test reactions were 2+ for dandelion (Taraxacum officinale), false ragweed (Ambrosia acanthicarpa), giant ragweed (Ambrosia trifida), short ragweed (Ambrosia artemisifolia), sagebrush (Artemisia tridentata), wild feverfew (Parthenium hysterophorus), yarrow (Achillea millifolium), and tansy (Tanacetum vulgare) and 1+ for Dahlia species and English ivy (Hedera helix).
Ambrosin
Definition:
(n.) An early coin struck by the dukes of Milan, and bearing the figure of St. Ambrose on horseback.
Example Sentences:
(1) The source of the epidemic are the strong sensitizing sesquiterpene lactones parthenin, ambrosin and others, which are highly concentrated in the trichomes of the plant.
(2) The molluscicidal properties of Damsin "I", Ambrosin "II", and tribromodamsin "III" were investigated against the intermediate hosts of schistosomiasis Biomphalaria alexandrina and Bulinus truncatus.
(3) Using an aqueous extract of the plant material of A. maritima or using ambrosin, one of the active molluscicidal components of the plant, no mutagenic activity could be detected in the S. typhimurium strains TA97, TA 98, TA1538, TA100 and TA1535.
(4) The most frequently encountered positive responses were to alantolactone (positive in all cases) and to arbusculin A, 8-deoxycumambrin, ambrosin, damsin and psilostachynin.
