ABSTRACT
The morphological differentiation of the infective larvae between human Ancylostoma duodenale and Necator ameri-canus is of great significance for the epidemiological survey of hookworm diseases and human parasitology teaching.Understand-ing of features of the oral spear and transverse lines on the tunica vaginalis is able to accurately differentiate the infective larvae between these two human hookworms.
ABSTRACT
Artemisia lactiflora is an important medicinal plant in China. The antitumor and antioxidant activities of the extracts of 54 endophytic fungi from the plant were screened via MTT assay and DPPH scavenging radical assay, respectively. The bioactive strains were identified based on similarity of 5.8S gene and internal transcribed spacer (ITS) sequences. The results showed that extracts from ten (18.5%) isolates exhibited antitumor activity, and which from two (3.7%) isolates exhibited antioxidant activity. The Alternaria sp. GYBH47 strain was simultaneously having antagonistic activity against HL-60 leukemia, MCF-7 breast and COLO205 colon cell lines, and Phomopsis sp. GYBH42 strain having cytotoxic and antioxidant activities. The results indicated that endophytic fungi from Artemisia lactiflora are potential resources to find valuable bioactive components.
