Camellia oil, widely used for cooking, could possibly have medicinal qualities that could alleviate the effects of stomach ulcers brought on by alcohol use, a medical research team at National Chung Hsing University said on Tuesday.
The latest mice studies headed by professor of food science and biotechnology Yen Kuo-chin (顏國欽) showed mice pretreated with camellia oil suffered less from alcohol-induced acute gastric mucosal injury, the press release said.
Long used in Taiwan for cooking, folk wisdom asserts that camellia oil has properties that alleviate stomach ailments, a claim the study sought to research, Yen’s team said in a June 21 paper published in the Journal of Agricultural and Food Chemistry.
Alcohol causes stomach disorders because it elevates the stomach tissue’s oxidative stress, suppresses the expression of heat shock proteins and interferes with Prostaglandin E2 production, the paper said.
Those effects reduce the regeneration and repair of gastric mucosa, making the stomach more vulnerable to inflammation and apoptosis and resulting in a higher rate of injury and ulcer risk, it said.
Camellia oil had a positive effect on the stomach’s ability to combat negative effects from ethanol in mouse cells, as well as in live mice, it said.
The in vitro study with mouse cells indicated that the oil helped enhance defenses, cell viability and wound healing while reducing apoptosis, it said.
Lab mice consuming the oil showed enhanced defenses, while inflammation, oxidative stress and apoptosis were down when compared to a control group, it said.
The mechanism causing the positive effects was that camellia oil enhances antioxidant enzyme activities, heat shock protein and Prostaglandin E2 production, while it suppresses lipid peroxidation, apoptosis-related proteins, and pro-inflammatory cytokines, the paper said.
Although results in lab mice are not necessarily replicable in people, the study’s results were encouraging and pointed toward potential health benefits, the university said.
The Coast Guard Administration (CGA) yesterday said it had deployed patrol vessels to expel a China Coast Guard ship and a Chinese fishing boat near Pratas Island (Dongsha Island, 東沙群島) in the South China Sea. The China Coast Guard vessel was 28 nautical miles (52km) northeast of Pratas at 6:15am on Thursday, approaching the island’s restricted waters, which extend 24 nautical miles from its shoreline, the CGA’s Dongsha-Nansha Branch said in a statement. The Tainan, a 2,000-tonne cutter, was deployed by the CGA to shadow the Chinese ship, which left the area at 2:39pm on Friday, the statement said. At 6:31pm on Friday,
The Chinese People’s Liberation Army Navy’s (PLAN) third aircraft carrier, the Fujian, would pose a steep challenge to Taiwan’s ability to defend itself against a full-scale invasion, a defense expert said yesterday. Institute of National Defense and Security Research analyst Chieh Chung (揭仲) made the comment hours after the PLAN confirmed the carrier recently passed through the Taiwan Strait to conduct “scientific research tests and training missions” in the South China Sea. China has two carriers in operation — the Liaoning and the Shandong — with the Fujian undergoing sea trials. Although the PLAN needs time to train the Fujian’s air wing and
The American Institute in Taiwan (AIT) put Taiwan in danger, Ma Ying-jeou Foundation director Hsiao Hsu-tsen (蕭旭岑) said yesterday, hours after the de facto US embassy said that Beijing had misinterpreted World War II-era documents to isolate Taiwan. The AIT’s comments harmed the Republic of China’s (ROC) national interests and contradicted a part of the “six assurances” stipulating that the US would not change its official position on Taiwan’s sovereignty, Hsiao said. The “six assurances,” which were given by then-US president Ronald Reagan to Taiwan in 1982, say that Washington would not set a date for ending arm sales to Taiwan, consult
A Taiwanese academic yesterday said that Chinese Ambassador to Denmark Wang Xuefeng (王雪峰) disrespected Denmark and Japan when he earlier this year allegedly asked Japan’s embassy to make Taiwan’s representatives leave an event in Copenhagen. The Danish-language Berlingske on Sunday reported the incident in an article with the headline “The emperor’s birthday ended in drama in Copenhagen: More conflict may be on the way between Denmark and China.” It said that on Feb. 26, the Japanese embassy in Denmark held an event for Japanese Emperor Naruhito’s birthday, with about 200 guests in attendance, including representatives from Taiwan. After addressing the Japanese hosts, Wang
