a Effects of LHQK on bodyweight of mice infected with SARS-CoV-2. Data are presented as Mean ± SD (n = 6 in each group). *P ≤ 0.05, **P ≤ 0.01 vs model group. b Effects of LHQK on viral load in lungs of SARS-CoV-2-infected hACE2 transgenic mice on day 5. Data are presented as Mean ± SD (n = 3 in each group). **P ≤ 0.01 vs model group. c Histopathological changes in lung tissues of SARS-CoV-2-infected hACE2 transgenic mice on day 5 after viral challenge as examined by HE staining (×200)
