Hwa-Jung Choi
Osong Public Health Res Perspect. 2018;9(6):348-353.   Published online December 31, 2018
Objectives

This study was conducted to determine whether essential oils had anti-influenza A/WS/33 virus activity and whether there were specific compounds associated with this activity.

Methods

There were 63 essential oils evaluated for anti-influenza (A/WS/33 virus) activity using a cytopathic effect reduction method. The chemical composition of the anti-influenza essential oils was phytochemically analyzed by gas chromatography-mass spectrometry.

Results

The antiviral assays demonstrated that 11...

Osong Public Health Res Perspect. 2017;8(6):415-420.   Published online December 31, 2017
Objectives

Rhinoviruses (RVs) cause common cold and are associated with exacerbation of chronic inflammatory respiratory diseases. Until now, no clinically effective antiviral chemotherapeutic agents to treat diseases caused by human rhinoviruses (HRVs) have been reported. We assessed the anti-HRV3 activity of sakuranetin isolated from Sorbus commixta Hedl. in human epithelioid carcinoma cervix (HeLa) cells, to evaluate its anti-rhinoviral potential in the...

Jae-Sug Lee, Hwa-Jung Choi, Jae-Hyoung Song, Hyun-Jeong Ko, Kyungah Yoon, Jeong-Min Seong
Osong Public Health Res Perspect. 2017;8(5):318-324.   Published online October 31, 2017
Objectives

Echovirus 30 is a major cause of meningitis in children and adults. The aim of this study was to investigate whether the antifungal drug itraconazole could exhibit antiviral activity against echovirus 30.

Methods

The cytopathic effect and viral RNA levels were assessed in RD cells as indicators of viral replication. The effects of itraconazole were compared to those of two known antiviral...

Brief Report
Evaluation of Antiviral Activity of Zanthoxylum Species Against Picornaviruses
Hwa-Jung Choi
Osong Public Health Res Perspect. 2016;7(6):400-403.   Published online December 31, 2016
Human rhinoviruses and enteroviruses (family Picornaviridae) infect millions of people worldwide each year, but little is known about effective therapeutical treatment for the infection caused by these viruses. We sought to determine whether or not Zanthoxylum (Rutaceae) species can exhibit antiviral activity against picornaviruses. The leaf parts of four Zanthoxylum species were extracted with methanol, and the extracts were investigated...
