WELLINGTON, May 13 (Xinhua) -- While it's long been known that a little sunshine can spread happiness, researchers in New Zealand have found that it can also save the lives of pneumonia patients.Medical scientists have found that vitamin D, which is absorbed through the skin and produced with exposure to sunlight, is a major factor in the survival rate of pneumonia patients.Researchers at Waikato University collaborated with doctors at Waikato Hospital, both Hamilton-based institutions, to study blood samples of 112 patients admitted to the hospital with pneumonia during the winter.They found that those with severe vitamin D deficiency 17 of the patients were more likely to die within a month, compared with patients with normal or slightly low vitamin D levels.Dr Bob Hancox, of the hospital's department of respiratory medicine, said five of the 17 died, a 29-percent mortality rate, compared with four deaths among the 95 patients with higher vitamin D levels, a 4-percent mortality rate."The analysis confirmed that the difference in mortality rates between the two groups was very unlikely to be due to chance," Hancox told Xinhua.Vitamin D deficiency was a concern around the world, Hancox said."Sunlight is the main source of vitamin D, so it tends to be a winter problem in temperate climates when people spend a lot of time indoors. But it occurs in all countries and vitamin D deficiency is believed to be a major problem worldwide."There is accumulating evidence that we need vitamin D to help fight infections, such as pneumonia as we have shown, as well as improve bone health," he told Xinhua."What is not yet clear is whether we can do anything about it. We don't know whether treating people with vitamin D supplements would help to prevent or treat respiratory infections. This is what we need to find out now."Dr Ray Cursons, of the Biological Sciences department at Waikato University, said patient age, sex, additional health conditions, and other prognostic factors did not affect the research outcome, although researchers still could not establish a causal link between vitamin D deficiency and mortality in the patients.Waikato Hospital D respiratory specialist Dr Noel Karalus said it was not yet known whether giving patients vitamin D supplements after their admission to hospital with respiratory tract infections would alter outcomes."It may transpire that vitamin D helps us avoid infection rather than cure it once established."Cursons said the best source of vitamin D was sunlight as dietary sources such as fatty fish and cod liver oil did not contain enough vitamin D."There is still some controversy regarding the optimal daily allowance of vitamin D. How much we absorb through the skin depends on sun exposure, skin type and geographical latitude. M ori and Pacific Islanders absorb less because of their darker skin, and people in colder climates also have lower levels of vitamin D. "Pneumonia is the single largest cause of death in children worldwide, killing an estimated 1.6 million children under the age of five each year, according to the World Health Organization.The research findings are published in the journal Respirology, published by the Asian Pacific Society of Respirology, this month.

MEXICO CITY, May 18 (Xinhua) -- The Mexican government signed an agreement with the non-governmental group TRAFFIC on Tuesday to exchange information about illegal seizures of flora and fauna species in Mexico.The agreement with the wildlife trade monitoring network also called for the Mexican government to provide information on the routes used to transport such organic materials.The agreement was signed on the sideline of the 16th meeting of the Trilateral Committee for Wildlife and Ecosystem Conservation Management in the city of Oaxaca, south Mexico. Representatives of Canada, the United States and Mexico also attended the meeting.Among the list of 20,000 animals, vegetation and insects that TRAFFIC considers to be threatened by illegal trafficking worldwide, 2,500 of the organisms have their origins in Mexico. This amounts to 12 percent of the species most subject to buying, selling and transporting in the black market and threatens the survival of various ecosystems.The Mexican species that are listed among the most threatened by illegal trafficking are the cactus, orchids, reptiles, maguey plants, ferns, amphibians and fish.

BEIJING, May 4 (Xinhuanet) -- No formalin has been found in the milk powder imported from S. Korea into China due to different milk sources, the general agency of South Korea's Maeil Dairies said Tuesday.The declaration came after Maeil Dairies, South Korea's third-largest dairy company, was found to have produced milk from cows given feed tainted with formalin.The agency said that the milk used in the dairy products exported to China comes from New Zealand, Europe and other places outside South Korea, so Chinese consumers should have nothing to worry about.Formalin, a liquid form of formaldehyde gas, was largely used in the past as a disinfectant, pesticide and bactericide for preservation of biological specimens.Its use has dwindled over the years due to health concerns.After the incident, South Korea has decided to conduct emergency inspections on milk sold in the market by four major dairy companies, to check the presence of formalin.

BEIJING, March 22 (Xinhua) -- China's State Food and Drug Administration (SFDA) has ordered a "serious investigation" into two kinds of bath products that reportedly gave children skin diseases.The order came after recent reports accused the body wash and lotion used by bathhouse chain Tian Po Po Xi Jiu Tang, or, literally, "Grandma Tian's Bathhouse," in southwest China's Sichuan Province of having "caused severe body damages," according to a SFDA statement released Tuesday.The bathhouse chain, with a history of some 70 years, was first established in Sichuan's capital Chengdu and was listed as a part of the city's Intangible Cultural Heritage in 2009.The licensed bathhouse claimed to use bath products developed by its own Chinese herbal medicine recipes that protected children from various skin ailments and other diseases, such as eczema, colds, and constipation.However, an unknown number of children suffered pustular psoriasis, a chronic skin irritation characterize by raised bumps, after washing at the bathhouse chain and using the two products, according to reports.Sichuan's provincial food and drug administration bureau previously deemed the two products to be "fake drugs" based on an initial investigation by the local police and food and drug authorities, the statement said.The SFDA urged local food and drug supervision departments across the country to monitor and check the two products sold by the bathhouse chain within their regions, and vowed to punish any violations of laws and regulations.
