Reviewing Threats to Wild Rhodiola sachalinensis, A Medicinally Valuable yet Vulnerable Species

Occurring in China, DPR Korea, Japan, and Russian Federation and classified in the Red List of Chinese Flora as a vulnerable species, Rhodiola sachalinensis Boriss. is used increasingly in cosmetics, dietary supplements, and Traditional Chinese Medicines (TCMs). The aim of this study was to evaluate the (i) conservation status, harvesting and trade levels of R. sachalinensis,(ii) current state of experimental and commercial farming, and (iii) evidence of substitution or interchangeable use of R. sachalinensis with other Rhodiola species. We assessed data from multiple disciplines and languages including studies on R. sachalinensis biology and ecology, information on impacts of wild harvest, management measures, and current levels of cultivation. Our assessment shows that while R. sachalinensis is increasingly produced by cultivation, wild populations are decreasing and face multiple threats. These include (a) habitat loss including due to oil and gas infrastructure development on Sakhalin island,(b) climate change impacts on alpine ecosystems, and (c) overexploitation of wild plants to satisfy the growing commercial demand. Assessments of the conservation status of R. sachalinensis should commence in each Range State, as well as resource assessments and monitoring of harvesting and trade of wild R. sachalinensis. Even with increased reliance on cultivation, biodiversity conservation, and genetic diversity in wild populations are relevant to future use of this species.     

The clinics of HHV‐6 infection in COVID‐19 pandemic: Pityriasis rosea and Kawasaki disease

A new type of coronavirus family (SARS‐CoV‐2), which can be found in humans and animals, with many varieties and clinical symptoms, was first seen in Wuhan, China in late 2019, under the name novel Coronavirus Disease 2019 (COVID‐19). In the literature, cutaneous symptoms related to the disease are generally emphasized. However, it is not yet known whether this new SARS‐CoV‐2 virus, which has entered our lives, plays a role in the etiopathogenesis of dermatological diseases. The patients who were admitted to the dermatology outpatient clinic between 1 April and 15 May 2019, and on 1 April and 15 May 2020 were retrospectively analyzed by searching the hospital automation system and patient files. The reason for the same months to be included in the study was to exclude seasonal effects on the diseases. After pandemic, the number of patients with Pityriasis rosea and Kawasaki disease increased significantly in patients who applied to the dermatology outpatient clinic. Our study is the first study showing Pityriasis rosea increase during the pandemic period. We think that this increase is related to HHV‐6 reactivation. Herein, we wanted to draw attention to two diseases in which Human Herpes 6 (HHV‐6) was accused in etiopathogenesis: Kawasaki disease and Pityriasis rosea.
