Investigation of the Antiviral Effects of Saussurea lappa Root Extract against SARS-CoV-2 Virus.

SCOPE: The purpose of this study was to look into the antiviral activity of a plant extract derived from the roots of the Saussurea lappa as a food supplement against SARS-CoV-2 infection. METHODS AND RESULTS: Vero E6 cells are employed in the study to test the neutralizing effect of Saussurea lappa extract against the SARS-CoV-2 virus. For anti-viral activity detection, a sensitive real-time cell analyzer (xCELLigence RTCA) with a high repetition rate is used. A challenge experiment in mice is planned as a result of the in vitro analysis. A challenge test against SARS-CoV-2 is performed with 10 adult female K18-hACE2 transgenic mice in each group for this purpose. The mice in the S. lappa Group are gavaged 2 days before the virus is administered intranasally (i.n.). The control group received PBS instead of the extract. SARS-CoV-2 virus is administered i.n. under anesthesia for the first 3 days of the experiment, and S. lappa extract was administered by gavage in the afternoon. On the 10th day, mice in the S. lappa group survived the study, whereas animals in the control group grew ill and/or died. In this study, the extract protects the mice against the SARS-CoV-2 virus in 90% of the cases. CONCLUSIONS: This study demonstrates that the Saussurea plant has antiviral effects against SARS-CoV-2 in vitro and in animal models.

Relation of metabolic syndrome with endometrial pathologies in patients with abnormal uterine bleeding.

PURPOSE: We aimed to investigate the association of metabolic syndrome and metabolic risk factors with endometrial hyperplasia and carcinoma among women with abnormal uterine bleeding (AUB). METHODS: This study included 199 patients who had undergone endometrial curettage due to abnormal uterine bleeding. We divided the patients into two groups according to whether they had an abnormal (n = 53) or normal endometrium (n = 146). Waist circumference, blood pressure, fasting glucose and serum lipid levels were measured and statistically analyzed. The women in each group were matched with regard to mean age, gravidity, parity and menopausal status. RESULTS: We found increased prevalence of metabolic syndrome, diabetes, general and abdominal obesity, hypertension, elevated levels of glucose, total cholesterol and LDL-cholesterol and reduced levels of HDL-cholesterol among women with endometrial carcinoma and hyperplasia. These results were detected particularly in postmenopausal (>50 years) women compared to pre-menopausal cases (<50 years). All metabolic parameters were similar between hyperplasia and cancer groups. CONCLUSION: Metabolic syndrome and its components have been shown to have profound impacts on initiation and progession of endometrial pathology, particularly during post-menopausal period.

A case of rhabdomyolysis complicated with acute renal failure after resumption of fenofibrate therapy: a first report.

Adverse effects due to use of fibrates often relate to the skeletal muscle, kidneys, or liver. Rhabdomyolysis is a most serious potential adverse effect. We present a case of resumed fenofibrate induced rhabdomyolysis complicated with acute renal failure.
