What's the difference between bergamot and burgamot?
Bergamot
Definition:
(n.) A tree of the Orange family (Citrus bergamia), having a roundish or pear-shaped fruit, from the rind of which an essential oil of delicious odor is extracted, much prized as a perfume. Also, the fruit.
(n.) A variety of mint (Mentha aquatica, var. glabrata).
(n.) The essence or perfume made from the fruit.
(n.) A variety of pear.
(n.) A variety of snuff perfumed with bergamot.
(n.) A coarse tapestry, manufactured from flock of cotton or hemp, mixed with ox's or goat's hair; -- said to have been invented at Bergamo, Italy. Encyc. Brit.
Example Sentences:
(1) Phototoxicity of bergamot oil in solar simulating radiation (SSR greater than or equal to 290 nm) and in long ultraviolet radiation (LUV greater than or equal to 320 nm) has been compared by studying photoaugmentation of erythema in the guinea pig after 24 h and pigmentary photoaugmentation in man on the 8th day.
(2) Our insights are related mainly to information gained from bergamot, an obvious form of clinical toxicity that long awaited simply animal or human models for experimental study.
(3) A comparison of 5-MOP at 50 ppm in bergamot oil with 5-MOP at 50 ppm prepared from pure 5-MOP crystals shows identical results, indicating that the active phototumorigenic agent in bergamot oil is 5-MOP and not other related compounds, which may be present at greater concentrations.
(4) Citropten (5,7-dimethoxycoumarin) and bergapten (5-methoxypsoralen) are present in bergamot oil which is used as a cosmetic tanning product.
(5) As part of an international cooperative study of the photophysical, photomutagenic and photocarcinogenic properties of bergamot oil and the effect of UVA and UVB sunscreens, the phototoxic properties of model perfumes containing 5, 15 and 50 ppm 5-methoxypsoralen (5-MOP) in bergamot oil with and without a sunscreen have been investigated on human skin.
(6) This difference of sensitivity necessarily implies the participation of UVA (320--400 nm) in the phototoxic reaction of bergamot oil with solar radiation.
(7) However, despite their promising protective effect in vitro, UVB and UVA sunscreens at low concentration (0.5%-1%) in perfumes cannot suppress the phototoxicity of bergamot oil on human skin.
(8) The addition of sunscreens in a model perfume containing 50 ppm 5-MOP in bergamot oil can reduce the phototoxic properties of this perfume to a toxicity equivalent to that produced by the application of a model perfume containing 15 ppm 5-MOP without sunscreens.
(9) Research with phototoxic agents relevant to man has been usually related to their clinical toxicity potential (bergamot dermatitis) or attempts to harness their toxic properties for the therapy of vitiligo and psoriasis.
(10) Techniques for assessing the phototoxic components of oil of bergamot are described and quantitative analyses of bergapten, the only significant photoactive compound in the samples examined, are reported.
(11) The discovery of the association of porphyrins with some light-related skin diseases and of the capability of chemical agents such as coal tar and bergamot to induce phototoxic contact dermatitis resulted in a flurry of clinical investigations leading to better understanding of the processes of phototoxicity and photoallergy.
(12) The skin of the female hairless albino mouse (Skh 1) was used to study the enhancement of solar simulated radiation (SSR) tumorigenesis by 5-methoxypsoralen (5-MOP) in model perfumes that contain bergamot oil.
(13) This UVA participation is particularly obvious in the guinea pig; in man, the results are less clear and a certain synergy of UVB rays (290--320 nm) may be involved in the phototoxic UVA-induced reaction of bergamot oil.
(14) It is important in the technique of photopatch testing, using oil of bergamot, to have determined the concentration of the active psoralen, bergapten, so as to avoid false negative responses in the assessment of phototoxic reactions.
(15) Citropten (5,7-dimethoxycoumarin) and bergapten (5-methoxypsoralen) are present in bergamot oil which is used as a tanning cosmetic product.
(16) On UV irradiation of bergamot oil, type II photodynamic properties, i.e.
(17) In order to determine the genotoxic potential of bergapten (5-methoxypsoralen (5-MOP] and bergamot oil (BO), the genetic effects of 5-MOP and BO (containing equivalent amounts of 5-MOP) were studied in haploid and diploid yeast (Saccharomyces cerevisiae) using solar simulated radiation (SSR).
(18) The results show that a close relationship exists between guinea pig and human responses, with both radiations used, and that man seems to be slightly more sensitive to phototoxic effects of bergamot oil than the guinea pig.
(19) Using a standardized open photopatch test technique, the phototoxic reactions produced by bergamot oil bergapten (5-methoxypsoralen) the active component of the oil, and xanthotoxin (8-methoxypsoralen) were studied.
(20) Therefore bergamottin can be considered as a potential photosensitizer in the photobiological activity of bergamot oil.
