| light and electron microscopic investigation of in vitro starch synthesis in chromoplasts. | chromoplasts having a globular inner structure in the petals of forsythia suspensa can form starch grains in their stroma when incubated with glucose solution. the same result was obtained with chromoplasts, similar in structure, from laburnum anagyroides and ranunculus acer. fibrillar chromoplasts in tepals of lilium croceum are able to synthesize starch in vitro, not, however, from glucose but from glucose-1-phosphate. this starch differs from the above mentioned both in respect of electron mi ... | 1979 | 552307 |
| [lectin histochemistry of human placenta in the normal state and in uterine inertia]. | the lectin-peroxidase technique has been used. the peanut lectin is able to label selectively kashchenko--hofbauer cells, villi of the chorion; the soya lectin--decidual cells in the maternal part of the placenta. prolonged labour development is connected with disappearance of kashchenko--hofbauer cells, with a reduced binding of the laburnum anagyroides lectin in combination with an intensified peanut lectin and concanavalin a binding with glycopolymeres of the villi of the chorion. | 1991 | 1789754 |
| myopathy in cattle induced by alkaloid extracts from thermopsis montanta, laburnum anagyroides and a lupinus sp. | a purified alkaloid preparation containing n-methylcytisine, cytisine, 5,6-dehydrolupanine, thermopsine and anagyrine from thermopsis montana induced prolonged recumbency and microscopic acute hyaline skeletal myodegeneration with myofibre regeneration in cattle similar in type and severity to that induced by thermopsis montanta plant material. this indicates that the alkaloid(s) of thermopsis montana are responsible for the myopathy caused by the plant. an alkaloid preparation containing mostly ... | 1990 | 2246392 |

| [populations of afferent neurons in the sensory ganglia detected using lectin from laburnum anagyroides]. | the purpose of the present research was the study of afferent neuron subpopulations in vagal caudal ganglia and trigeminal ganglion of adult albino rats using a conjugate of fucose-specific laburnum anagyroides lectin (lal) with peroxidase. histochemical preparations obtained were examined using computer videoanalyzer with the determination of dimensions of afferent neurons and integral optical density (iod) of their cytoplasm. in the ganglia studied lal was found to bind to the majority (more t ... | 2003 | 14994587 |
| qualitative and quantitative variation among volatile profiles induced by tetranychus urticae feeding on plants from various families. | many plant species are known to emit herbivore-induced volatiles in response to herbivory. the spider mite tetranychus urticae koch is a generalist that can feed on several hundreds of host plant species. volatiles emitted by t. urticae-infested plants of 11 species were compared: soybean (glycine max), golden chain (laburnum anagyroides), black locust (robinia pseudo-acacia), cowpea (vigna unguiculata), tobacco (nicotiana tabacum), eggplant (solanum melalonga), thorn apple (datura stramonium), ... | 2004 | 15074658 |
| fatal cytisine intoxication and analysis of biological samples with lc-ms/ms. | we report about a fatal cytisine intoxication in a 20-year-old man who, according to his mother, had drunken tea prepared from plant material of laburnum anagyroides with the toxic pyridine-like alkaloid as ingredient, which exhibits pharmacological effects similar to nicotine. using a liquid chromatographic-mass spectrometric (lc-ms) procedure cytisine was quantified in post-mortem specimens. by exclusion of other causes of death an intoxication was determined as the cause of death with respira ... | 2009 | 19217730 |
| nicotinic plant poisoning. | a wide range of plants contain nicotinic and nicotinic-like alkaloids. of this diverse group, those that have been reported to cause human poisoning appear to have similar mechanisms of toxicity and presenting patients therefore have comparable toxidromes. this review describes the taxonomy and principal alkaloids of plants that contain nicotinic and nicotinic-like alkaloids, with particular focus on those that are toxic to humans. the toxicokinetics and mechanisms of toxicity of these alkaloids ... | 2009 | 19778187 |
| stromatonectria gen. nov. and notes on myrmaeciella. | myrmaeciella caraganae was recollected in and around vienna, austria and found to be morphologically different generically from the type species of myrmaeciella, m. endoleuca. we redescribe m. caraganae in the new genus stromatonectria. phylogenetic analyses of lsu sequences place the genus in the bionectriaceae, hypocreales. s. caraganae occurs on branches of caragana spp., colutea arborescens and laburnum anagyroides of the fabaceae. it is characterized by spheroid perithecia partly or entirel ... | 2010 | 21139029 |
| survey of microfungi in the landschaftspark duisburg-nord (germany). | during an excursion in the landschaftspark duisburg-nord in 2009 and 2010 we were able to collect and identify more than 100 specimens of microfungi on different parts of cultivated and wild plant species. we found parasitic and saprophytic microfungi on trees, bushes and herbaceous plants. some of them have been observed only rarely until now. most of the collected microfungi species belong to the classes of ascomycetes, basidiomycetes and deuteromycetes - for example leptosphaeria modesta (des ... | 2011 | 22702187 |
| [intoxications with plants]. | ingestions of plants rarely lead to life-threatening intoxications. highly toxic plants, which can cause death, are monkshood (aconitum sp.), yew (taxus sp.) and autumn crocus (colchicum autumnale). lethal ingestions of monkshood and yew are usually suicides, intoxications with autumn crocus are mostly accidental ingestions of the leaves mistaken for wild garlic (allium ursinum). severe intoxications can occur with plants of the nightshade family like deadly nightshade (atropa belladonna), angel ... | 2009 | 19401984 |
| lectinocytochemical detection of apoptotic murine leukemia l1210 cells. | various cytomorphologic and biochemical markers of apoptosis are found in different compartments (plasma membrane, cytoplasm, nucleus, and mitochondria) of target cells. although the plasma membrane is an easily accessible cellular compartment, relatively little is known about its changes during apoptosis. we investigated whether specific changes in the expression of plasma membrane glycoproteins take place during apoptosis and whether these changes could be used for a quantitative estimation of ... | 2003 | 14608636 |
