BODY

In the June 2019 issue of Preventive Nutrition and Food Science (2019;24(2):159-164), a correction is necessary in the article “Cudrania tricuspidata Extract Protects against Reflux Esophagitis by Blocking H2 Histamine Receptors” by Joo Yun Kim, Sung Sik Jang, Jung Lyoul Lee, Jae-Hun Sim, and Jae-Jung Shim.

On page 160, errors were made in the MATERIALS AND METHODS. The corrected METHODS is printed below.

MATERIALS AND METHODS

Preparation of C. tricuspidata extract

Dried C. tricuspidata leaves were pulverized to an appropriate size and placed in an extraction vessel. Ethanol (0% to 70%, corresponding to 10 times the weight of the leaves) was added to the extraction vessel, refluxed, and stirred at 50°C~60°C for 16 h. C. tricuspidata extracts were adsorbed and filtered to remove insoluble impurities. The filtered juice extract was concentrated using a rotary vacuum evaporator (EYELA, Tokyo, Japan), lyophilized, pulverized, and powdered. The dried materials were resuspended in 0.5% methyl cellulose (MC) for animal experiments and in dimethyl sulfoxide (DMSO) for cellular experiments.

These amendments do not alter the conclusions of the paper.
