High Stress May Damage Memory
According to a report issued in May 1998，elderly people who have consistently high b1ood levels of cortisol don’t score as well on memory tests as their peels with lower levels of the stress hormone．What’s more． high 1evels of cortisol are also associated with shrinking 0f the hippocampus，a region of the brain that plays a key role in learning and memory．The 6ndings suggest that even cortisol levels in the normal，“healthy” range can actually accelerate brain aging．
The study results “now provide substantial evidence that long—term exposure to adrenal stress hormones may promote hippocampal aging in normal elderly humans，”write Nada Porter and Philip Landfield of the University of Kentucky in Lexington in their editorial．Cortisol is a hormone released in response to stress by the adrenal glands，which sit on top of the kidneys．
Over a 5 to 6一year period，Dr． Sonia Lupien and his colleagues measured 24一hour cortisol levels in 51 healthy volunteers，most of Whom were in their 70s．
Despite wide variation in cortisol levels．the participants could be divided into three Subgroups：those whose cortisol progressively increased over time and was currently high（increasing／high）：those whose cortisol progressively increased over time and was currently moderate（increasing／moderate）；and subjects whose cortisol decreased，but Was currently moderate（decreasing／moderate）．
The researchers tested the volunteers’ memory on six people in the increasing／high category and five people in the decreasing／moderate group．The groups did not differ on tests of immediate memory，but the increasing／high cortisol group had other memory problems compared with those in the decreasing／moderate group．
The researchers also found that the total volume of the hippocampus in those in the increasing／high group was 14％ lower than those in the decreasing／moderate group，although there were no differences in 0ther brain regions．
The results suggest that brain aging Can be accelerated by levels of adrenal hormones that are not generally regarded as pathological and that variation within this normal range is related to variation in the rate of brain aging．”write Porter and Landfield．“This further suggests that chronic stress may accelerate the worsening of hippocampus．”
第 26 题 The part of the brain important for a person’s learning and memory is．
A．the cortisol．
B．the adrenal glands．
C．the stress hormones
D．the hippocampus．
Passage Two
Questions 62 to 66 are based on the following passage.
Yoga induces a feeling of well-being in healthy people, and can reverse the clinical and biochemical changes associated with metabolic syndrome, according to results of studies from Sweden and India. Metabolic syndrome is a cluster of heart disease risk factors such as high blood pressure, obesity and high blood sugar.
Dr. R.P. Agrawal, of the SP Medical College, Bikaner, India, and colleagues evaluated the beneficial effects of yoga and meditation in 101 adults with features of metabolic syndrome. In the study, 55 adults received three months of regular yoga including standard postures and Raja Yoga,while the remaining received standard care.
Waist circumference, blood pressure, blood sugar, and triglyceri HDL cholesterol levels were higher in the yoga group as compared joumal Diabetes REsearch and Clinicat Practice.
In the second study, published online December 19 in BioMed Central Complementary and Alternative Medicine, Dr. Anette Kjellgren from the University of Karlstad, Sweden and colleagues evaluated the beneficial effects of yoga-like breathing exercises on healthy volunteers.
55 adults were advised to practice "Sudarshan Kriya," which involves cycles of slow, normal and rapid breathing exercises. The exercises were practiced for an hour daily, six days a week for six weeks, while 48 controls were advised to relax in an armchair for I 5 minutes daily.
At the end of the study period, feelings of anxiety, stress and depression were significantly lower and levels of optimism significantly higher in the yoga group compared to the control group, Kjellgren and colleagues report.
Yoga induces a "relaxation response" associated with reduced nervous system activity and a feeling of well-being probably due to an increase in antioxidants(抗氧化剂) and lower levels of the stress hormone cortisol(应激激素皮质醇 ), they suggest.
Yoga not only helps in prevention of lifestyle. diseases, but can also be "a powerful adjunct therapy when these diseases anse,” co-investigator Dr. Faahri Saatiglou, from the University of Oslo, told Reuters Health. "We do not emphasize this point enough in our Westem health care."
The studies of yoga from Sweden and India have shown that __
A. yoga will make patients recover more quickly
B. yoga can cure cancer gradually
C. yoga will lead the state of being healthy
D. yoga can keep people optimistic
What could be said about the adrenalin？ ()
A．It is secreted by the kidneys into the bloodstream.
B．It is hormone that prepares the body for emergencies.
C．It is the only useful hormone produced in the body.
D．It is essential to sustain life.
What problems does sport have？
A．Some women athletes are actually men.
B．Some women athletes are given hormone injections.
C．Women and men do not run or swim in the same races.
D．It is difficult to check whether women athletes are really women.
In sport the sexes are separate. (76) Women and men do not run or swim in the same races. Women are less strong than men. That at least is what people say. Women are called "the weaker sex" ,or, if men want to please them, "the fair sex". But boys and girls are taught together at schools and universities. There are women who are famous Prime Ministers, scientists and writers. And women live longer than men. A European woman can expect to live until the age of 74, a man only until he is 68. Are women' s bodies really weaker7
The fastest men can run a mile in 4 minutes. The best women need 4.5 minutes. Women' s speeds are always slower than men' s, but some facts are surpising. Some of the fastest women swimmers today are teenage girls. One of them swam 400 metres in 4 minutes 21.2 seconds when she was only 16. The first "Tarzan" in films was an Olympic swimmer, Johnny Weissmuller. His fastest 400 metres was 4 minutes 59.1 seconds, which is 37.9 seconds slower than a girl 50 years later! This does not mean that women are catching men up. Conditions are very different now, and sport is much more serious. It is so serious that some women athletes are given hormone(荷尔蒙) injections. At the Olympics a doctor has to check whether the women athletes are really women or not. It seems sad that sport has such problem. Life can be very complicated when there are two separate sexes !
Women are called "the weaker sex" because______.
A．women do as much work as men
B．people think women are weaker than men
C．sport is easier for men than for women
D．in sport the two sexes are always together
