Shiitake Culinary-Medicinal Mushroom, Lentinus edodes (Agaricomycetes): Absence of Changes in Maternal Reproductive Performance and Embryofetal Development In Vivo.

Metadata-grounded summary

Citation abstract

The shiitake culinary-medicinal mushroom Lentinus edodes (=Lentinula edodes) has been used as a nutritional complement. This study evaluated, through reprotox tests, the consumption of L. edodes in pregnant rats, considering it as a functional food. Pregnant rats were daily exposed to L. edodes before implantation (LeB)-from 1 to 19 days of gestation, and after implantation (LeA)-from 9 to 19 days of gestation, compared with controls. On the 20th day of gestation, cesarean sections were performed. Blood was collected and hematological parameters (hemoglobin, hematocrit, white and red blood cells and platelets) were analyzed. Moreover, albumin, calcium, creatine kinase, alkaline phosphatase, transferases, creatinine, urea, triglycerides, cholesterol, lipase, glucose, and insulin were assessed in serum. Organs were collected and weighed, and the fetuses were analyzed morphologically by body measurements. The consumption of L. edodes reduced triglycerides levels and there were no changes in maternal weight, biochemical and hematological parameters, organ weight, and reproductive capacity. There were no morphological changes in the fetuses' body measurements, suggesting possible safety in ingestion of mushroom. Reprotox tests used to evaluate the daily consumption of L. edodes points out potentiality as a functional food, suggesting safety during the gestational period.
