Última In Vitro Genotoxic Effects of Four Helichrysum Species in Human Lymphocytes Cultures Biol. Res. Erolu,Erhan H; Hamzaolu,Ergin; Aksoy,Ahmet; Budak,Ümit; Özkul,Yusuf. Helichrysum sanguineum, Helichrysum pamphylicum, Helichrysum orientale, Helichrysum noeanum (Asteraceae) are medicinal plants. For centuries, they have been used as tea in Turkey because of their medicinal properties. So far no scientifc evidence has been found in a literature survey regarding the genotoxic effects of these plants. This work evaluated the genotoxic effects on human lymphocyte cultures induced by methanol extracts of these plants, assayed in different concentrations (0.01, 0.05, 0.1, 0.5 and 1 mg/mL). According to the results, Helichrysum noeanum, Helichrysum pamphylicum and Helichrysum sanguineum induced the formation of micronuclei and decreased the mitotic and replication indexes. Helichrysum orientale did not affect these parameters,... Tipo: Journal article Palavras-chave: Genotoxic; Helichrysum; Micronucleus; Mitotic index; Replication index. Ano: 2010 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-97602010000200005 Karyotype and genome size analyses in species of Helichrysum (Asteraceae) Acta Botanica Azizi,Narjes; Sheidai,Masoud; Mozaffarian,Valiollah; Nourmohammadi,Zahra. Karyotype studies were performed in 18 populations of eight Helichrysum species in Iran. Those species showed chromosome numbers of 2n = 2x = 14; 2n = 4x = 24, 28 and 32; 2n = 6x = 36; 2n = 7x = 42; 2n = 8x = 48; 2n = 9x = 54; and 2n = 10x = 60. The chromosome numbers of H. davisianum, H. globiferum, H. leucocephalum and H. oocephalum are reported here for the first time. New ploidy levels are reported for H. oligocephalum (2n = 4x = 24) and H. plicatum (2n = 4x = 32). The chromosomes were metacentric and submetacentric. An ANOVA among H. globiferum and H. leucocephalum populations showed significant differences for the coefficient of variation for chromosome size, total form percentage and the asymmetry indices, indicating that changes in the chromosome...
