1
PLANTE FOTOSENSIBILIZANTE
2
Fam. Apiaceae, Rutaceae, Asteraceae, Ranunculaceae Derivati de benzopiran, biantrone, poliine Leziuni: maini, picioare, trunchi
3
hipericina = fotosensibilizare ulei volatil taninuri hipericina
4
Hipericismul = in urma expunerii la soare: - mancarimi, eriteme dureroase, necroze ale pielii - fenomene neurologice (excitatii psihomotorii, convulsii, moarte prin hiperemia creierului)
5
Fagopirina = fagopirism ( tulb la nivelul pielii depigmentate si expuse la soare, tulb neurologice)
6
Comp. chimica: - Furanocumarine - Ulei volatil (cetone alifatice, alcooli alifatici) Intoxicatia: salivatie abundenta, gastroenterite dureroase, hemoragii uterine, nefrita profunda
7
Comp. chimica: furanocumarine Fototoxicitate = hiperpigmentare (leucodermii – vitiligo) Fotosensibilizare = expunere la soare; tratament indelungat = cancerogenicitate
8
Comp. chimica: Ulei volatil (miros de ambra – lactone macrolidice) = α, β – pinen, limonene, acidul valerianic, angelic Cumarine (umbeliferona) Furanocumarine (angelicina) Fototoxicitate
9
PLANTE CU TOXALBUMINE = LECTINE
10
Fam. Fabaceae, Euphorbiaceae, Myrtaceae, Loranthaceae Prop. imp: eritroaglutinare, citoaglutinare (stabilirea grupei sanguine; determinarea cariotipului; diagnostic si tratament de cancer)
11
Comp. chimica: - proteine (viscotoxine) - glicoproteine (viscumine) DL 50 = 100μg/ kg corp viscumina
12
Toxicitate: Bacele = tulb neurologice si cardiovasculare Intoxicatie la copii ( 5 bace) = vomismente, diaree, somn, agitatie, colaps Frunzele = tulburari digestive, hipotensiune Viscotoxina = ↓HTA, modificari de ritm cardiac, tulburari nervoase (paralizie, pierderea sensibilitatii) NU SE UT EXTRACTE TIMP INDELUNGAT = HEPATITA
13
Comp. chimica: - proteina toxica = ricina (seminte) - alcaloid = ricinina (seminte)
14
Intoxicatie: Coagularea fibrinei, aglutinarea hematiilor, iritarea mucoaselor gastrointestinale, leziuni hepatice, nefrite, tulburari nervoase DL ad = 15 – 20 sem DL cop = 3 - 7 sem
15
Comp. chimica : a) fructe si radacina saponine triterepenica phytolaccagenin, jaligonic acid, phytolaccagenic acid (phytolaccinic acid), esculentic acid, and pokeberrygenin.These include phytolaccosides A, B, D, E, and G, and phytolaccasaponins B, E, and G. lectine b) fructele pigmenti din clasa betacianinelor
16
Intoxicatia: a) cu frunze = greturi, diaree, reactii digestive, perturbatii ale traseului ECG; simtomele apar la 3 h – 24 h; spitalizare, adm carbune activ b) cu radacina = arsura la nivelul gurii si gatului, hipersalivatie, dureri abdominale, diaree sangvinolenta, HTA, tahicardie, convulsii Phytolaccigenin causes hemagglutination.
