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 = 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.

17  VA MULTUMESC!
