The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

RÉSUMÉ

(1®3)-b-glucan content in extracts from various edible mushrooms was measured by using a (l®-6)-branched (1®3)-b-glucan-specific enzyme immune system. Comparing (1®3)-b-glucan content in hot water extracts or cold alkaline extracts of each edible mushroom, it was shown that Lentinus edodes (Berk.) Sing. contained higher levels of (1®3)-b-glucan than any of the other mushrooms. Cold alkaline extract possessed the highest amount of (1®3)-b-glucans. Interestingly, a cold alkaline extract from premixed dried powder of the mushrooms showed a higher level of (1®3)-b-glucan following calculation as sonifilan than the theoretical total amount of each (1®3)-b-glucan extract from each constituent mushroom from which premixed dried powder was prepared. Considering the specificity of this enzyme immunoassay as previously reported, it is suggested that premixed extraction contains Conformationally stable (1®3)-b-glucans. Antitumor activity of these mushroom extracts was also tested using a murine experimental model. All of the extracts showed higher antitumor activity and the effectiveness on inhibition of tumor growth in sold form was almost equal. Activation of macrophages by co-cultivation with the various extracts was induced with the premixed extract significantly higher. Induction of interferon-y was also enhanced by administration of the premixed extract. The premix extract showed modulating effect on glucocorticoid release induced by restraint stress. These results suggest that the mixture of mushroom extracts may provide physicochemically stable (1®3)-b-glucans and physiologically active products. A complementary effect of each mushroom component on enhancing immunological function would be expected by the mixed extraction.font face=
