The clinical signs began 8 hours after introduction of the animals into the new pasture and included apathy, anorexia, abdominal retraction or mild distension, weakness of hind limbs. Allelochemical regulation of se and seed germination of two Brazilian Baccharis species by phytotoxic trichothecenes. The potent phytotoxic trichothecene roridins and baccharinoids occur naturally in the Brazilian plants, Baccharis coridifolia andB.
Biosynthesis of roridins inB. The roles of the phytotoxins in pollination, seed maturation, and germination claaudio the Baccharis species were investigated. The high production of roridins occurred only in seeds resulting from intraspecific pollination, and the concentration of the toxins in the seeds generally increased with seed maturity.
Removal of seed coats from trichothecene-producing Brazilian Baccharis species B. Roridins interacted with gibberellic acid, a germination promoter, but not with abscisic acid, a germination inhibitor. The results from this study suggest that macrocyclic trichothecenes have a regulatory role s on reproduction and germination of Brazilian Baccharis species in their natural habitat.
Compositae dermatitis is an allergic contact dermatitis caused by plant species of the Compositae family. The first report of a cutaneous reaction to the Chrysanthemum genus was made by Howe JS in In Maiden JH reported about skin lesions among men working with Tagetes minuta.
Case reports of contact allergic-ragweed dermatitis appeared in the American literature as early as The North American feverfew–Parthenium Hysterophorus was brought to India from America in and it caused thousands of cases of so-called parthenium dermatitis.
Ragweed and parthenium dermatitis became prototypes for the classic, so-called “airborne” Compositae dermatitis, that affects primarily exposed skin surfaces, and produces a universal erythroderma. The frequency of contact allergy to Compositae in Europe is higher bertohi previously believed.
It occurs most paeo in middle-aged and elderly persons, but also in all age groups. During the two past decades a more equal sex ratio has been established. The prevalence varies from 0. Compositae allergy is among the top ten contact sensitivities in Europe. In North Europe plants were the cause of 4.

Sesquiterpene lactones are the main sensitizers of the Compositae family. Other components, thiophenes and acetylenes are said to elicit only phytophotodermatitis, but recent studies have demonstrated that some thiophenes and benzofuran derivates possess not only phototoxic activity, but also sensitizing properties.

The family Compositae is one of the largest in the plant kingdom. Several species are used in popular medicin. Thus, the leaf extract of Calea pinnatifida Banks, known as aruca, is employed in the treatment of amoebiasis. A chemical study is carried out in order to discover the active principles of the species.
Patch testing with constituents of Compositae mixes. The development of mixes containing Compositae plant extracts has improved the diagnosis of Compositae contact allergy, but none of them has fulfilled the criteria for an ideal European plant mix.

To evaluate which constituents of two commercial Compositae mixes were most u Cosmetics and herbal remedies with Compositae plant extracts – are they tolerated by Compositae -allergic patients? Compositae -sensitive patients are routinely warned against topical use of Compositae -containing cosmetics and herbal remedies. However, the risk of elicitation of dermatitis in presensitized persons is c,audio.
The main aim of this study was to assess paeo significance of d Colophonium and Compositae mix as markers of fragrance allergy: The individual results indicated that simultaneously occurring positive reactions to essential oils, colophonium and Compositae were based on cross-reactivity rather than concomitant sensitization. Thus, all patients with positive reaction to the rare fragrance The implication is that Compositae mix To evaluate which constituents of two commercial Compositae mixes were most useful as screening agents.
The majority of patients tested positive to parthenolide or parthenolide-containing extracts, followed by German chamomile, yarrow, and arnica. As German chamomile is a weak sensitizer, the results suggest cross-reactions or reactions to unknown allergens.
No one was positive to Roman chamomile.
Even though parthenolide seems to be a suitable supplement to the baseline series, the results emphasize that it is important to patch test with extracts of native or locally grown plants, not only because of the geographical variation, but also because of the potential unknown allergens contained in short ether preparations and the variability in the individual patient’s exposure and cross-reaction patterns.

Forty-three microfungi have been observed on thirty species of the Compositae occurring in several locations in the Ruhr Basin in North Rhine-Westphalia. Other fungi wich were found in our investigation belong to the Basidiomycetes Uredinales and to the Oomycetes Peronosporales. Some recorded microfungi have been discovered on new hosts in North Rhine-Westphalia and also in Germany for the first time. New for North Rhine-Westphalia are Ascochyta spec.

Contact sensitization from Compositae -containing herbal remedies and cosmetics. The Compositae Asteraceae family of plants is currently an important cause of allergic plant contact dermatitis in Europe.
The family comprises some of the oldest and most valued medicinal plants, and the increasing popularity of herbal medicine and cosmetics may theoretically result in a growing number of Compositae sensitizations from these sources. According to the literature at least 15 species, including among others arnica Arnica montanaGerman and Roman chamomile Chamomilla recutita and Chamaemelum nobilemarigold Calendula officinalisEchinacea and elecampane Inula heleniumhave been suspected of sensitization or elicitation of Compositae dermatitis.
Epidemiological data are available for 2 species only, arnica and German chamomile, the rest of the evidence being anecdotal.
Based on this, sensitization seems to occur relatively frequently with a few species such as arnica and elecampane, and occurs rarely with the majority, especially the widely used German chamomile. Sesquiterpene lactones are the most important allergens, but there are a few cases of sensitization from a coumarin, a sesquiterpene alcohol and a thiophene. The risk of elicitation of dermatitis by using Compositae -containing products in Compositae -sensitive individuals is lcaudio unknown.

Sunflowers may cause dermatitis because of allergenic sesquiterpene lactones SLs. Contact sensitization to sunflower seeds has also been reported, but the allergens are unknown.
To analyse sunflower seeds for the presence of Clauudio and to assess the prevalence of sunflower Sunflower-sensitive patients were identified by aimed patch testing. A dichloromethane extract of whole sunflower seeds was analysed by liquid chromatography-mass spectrometry and high-performance liquid chromatography.
A solvent wash of whole sunflower seeds yielded an extract containing SLs, the principal component tentatively being identified as argophyllin A or B, other SLs being present in minute amounts. Occupational dermatitis in Danish gardeners and greenhouse workers III.
The clinical part of the study aimed at describing epidemiological and diagnostic aspects of occupational Compositae dermatitis. Patch testing with the sesquiterpene lactone SL and Compositae mixes, feverfew extract and supplementary allergens in selected gardeners showed Compositae allergy in 25, 17 females and 8 males.
The mean age was lower and the preponderance of women higher compared to classical Compositae dermatitis, and the distribution and course of the dermatitis most often did not differ from other occupational plant dermatoses.
Chrysanthemum Dendranthemamarguerite daisy Argyranthemum frutescens and lettuce Lactuca sativa were frequent sensitizers. Occupational type I allergy to Compositae comprised sensitization to Gerbera, chrysanthemum, lettuce, Senecio cruentus and Aster.
Possible risk factors for the development of these were assessed in a stepwise logistic regression model and a history of childhood eczema, hay fever and duration of exposure were significantly associated with Compositae -related irritant and allergic symptoms in both sexes.
