Abstract. Mice model of the endurance and rat model of atmospheric oxygen were prepared in this paper. Study on the effect of Shenqi Pollen Tablet on altitude sickness. Shenqi Pollen Tablet could prolong survival time of mice、significantly reduce weight of rat right ventricular (RV) 、reduce leverage of the weight of right ventricular(RV) and left ventricular increases septum(LV+S),significantly reduce MDA level、NO level and NOS level、increase SOD level, improve hypoxia tolerance of organism.

By arriving at the South Pole on 14 December 1911, the Norwegian explorer Roald Amundsen (1872–1928) reached his destination over a month ahead of the British effort led by Captain Robert Falcon Scott (1868–1912). As Scott’s party approached the South Pole on 17 January 1912, they were devastated to see from afar the Norwegian’s black flag. On arrival, they discovered the remains of his camp with ski and sledge tracks, and numerous dog footprints. Amundsen, it turned out, had used dogs and diversionary tactics to secure victory while the British team had man-hauled their sledges. These differences were not lost on The Times in London, which marked the achievement with muted praise, declaring it ‘not quite in accordance with the spirit of fair and open competition which hitherto marked Antarctic exploration’. Exhausted, Scott and his men spent time the following day making scientific observations around the Pole, erected ‘our poor slighted Union Jack’, and photographed themselves in front of it (Plate 11). Lieutenant Bowers took the picture by pulling a string to activate the shutter. It is perhaps the most well known, and at the same time the saddest picture, of the entire expedition—a poignant image of the doomed party, all of whom look utterly fed up as if somehow sensing the fate awaiting them. The cold weather, icy wind, and dismal circumstances led Scott to acerbically remark in his diary: ‘Great god! This is an awful place and terrible enough to have laboured to it without the reward of priority.’ By this time, the party had been hauling their sledges for weeks, and all the men were suffering from dehydration, owing to fatigue and altitude sickness from being on the Antarctic plateau that sits nearly 3000m above sea level. Three of them, Captain Oates, Seaman Evans, and Bowers, were badly afflicted with frostbitten noses and cheeks. Ahead lay the return leg, made all the more unbearable by the crippling psychological blow of knowing they had been second to the Pole. After a gruelling 21-day trek in bitterly cold summit winds, the team reached their first cache of food and fuel, covering the distance six days faster than it had taken them to do the leg in the other direction.

Travel between developing countries and developed countries is increasing every year. Approximately 880 million passengers arrived at international airports in 2009. The increase in travel to Africa has outpaced the increase for all other regions by almost twice, with the rate of growth reaching 8.1% in 2006. Asian and Pacific Rim countries continue to hold substantial travel interest. Travel to the Middle East has kept pace with travel growth despite the political instability there. More people are traveling to destinations that present higher risks of infectious diseases. Knowledge of prevention measures for preventable diseases becomes increasingly important. Management of posttravel illness becomes increasingly important. Subjects covered include preparation for travel, deep vein thrombosis prevention, motion sickness, jet lag, altitude sickness, vaccination and immunization, and traveler's diarrhea.

At any point 1–5 days following ascent to altitudes ≥2500 m, individuals are at risk of developing one of three forms of acute altitude illness: acute mountain sickness, a syndrome of nonspecific symptoms including headache, lassitude, dizziness and nausea; high-altitude cerebral oedema, a potentially fatal illness characterised by ataxia, decreased consciousness and characteristic changes on magnetic resonance imaging; and high-altitude pulmonary oedema, a noncardiogenic form of pulmonary oedema resulting from excessive hypoxic pulmonary vasoconstriction which can be fatal if not recognised and treated promptly. This review provides detailed information about each of these important clinical entities. After reviewing the clinical features, epidemiology and current understanding of the pathophysiology of each disorder, we describe the current pharmacological and nonpharmacological approaches to the prevention and treatment of these diseases.
