【正文】 dic teams must be on hand at all boxing bills. The medical profession in several countries has increasingly adopted an antiboxing stance, citing irreversible brain damage as its major objection to the sport. This is a key point for, in absolute terms of deaths and serious injuries, other sports such as horseracing, mountaineering, rugby, and even cricket appear more dangerous, but in none of them is deliberate and repeated striking of an opponent part of the rules of the game. In contrast a boxer has a licence for physical assault. The evidence is clear that repeated pummelling to the head can cause cumulative damage to the brain: here time is no great healer. Occasionally, acute brain injury can occur during a fight. The greatest danger es towards the end when a tired man with a loose neck has his head flipped back rapidly by a punch. This can tear a vein outside or inside the brain, which then leaks blood, causing pressure on the brain and eventually leading to a a. Only if the clot is removed rapidly can the fighter survive. Fighters now train harder。s disorder (a related condition in which the baby develops in an apparently normal manner through age five months, and then begins to lose municative and social interaction skills). There is also evidence of a higher proportion of perinatal plications (plications arising around the time of giving birth) among children with autistic symptoms. These plications include maternal bleeding after the first trimester and meconium in the amniotic fluid. (Meconium is a substance that accumulates in the bowel of the developing fetus and is discharged shortly after birth.) Some evidence suggests that the use of medications during pregnancy may be related to the development of autistic symptoms. As newborns, children with autistic behaviors show a higher rate of respiratory illness and anemia than healthy children. ALLERGIES, INFECTIONS, AND IMMUNIZATIONS. Some professionals believe that autistic disorders may be caused by allergies to particular fungi, viral infections, and various foods. No controlled studies have supported these beliefs, but some parents and professionals report improvement when allergens and/or certain foods are eliminated from the diet. Viral infections of the mother, such as rubella, or of the young child, such as encephalitis, mumps, and measles, occasionally appear to cause autistic disorders. The mon childhood immunization series known as MMR (measles, mumps, rubella) has recently e under scrutiny as a possible cause of some autistic can make a true claim to being the only major sport that is an American invention. From high school to the professional level, basketball attracts a large following for live games as well as television coverage of events like the National Collegiate Athletic Association (NCAA) annual tournament and the National Basketball Association (NBA) and Women39。 antiboxing Bills proposed in parliament have failed to reach the statute books. Most schools, both state and public, however, have dropped boxing from their physical education curriculum. Yet it should be noted that amateur boxing is exceptionally well regulated: not more than four rounds are fought, headguards are worn, and the referee is allowed to stop a fight to prevent serious injury. However, headguards, whilst absorbing energy from punches, present an even larger target to be hit and thus the number of blows striking home may well increase. Indeed, studies have shown that nonboxing sportsmen outperform even amateur fighters in neurological tests and, notwithstanding the safety precautions, three amateur fighters have suffered serious brain injury in British rings since 1988. For centuries boxing has been the epitome of overt masculinity, a demonstration of manliness and its embodying characteristics of courage, toleration of pain, and selfdiscipline. Women were merely ornaments displaying the round cards. This continues, but women have successfully demanded equal rights in the ring. In Britain, girls from the age of 10 are now allowed to spar in amateur boxing gyms, and recently professionalism, too, has been recognized for women — significantly later than its acceptance in the US where fights for women have appeared on the undercard of world championship events. The moral dilemma of boxing is that it provides an honest opportunity to escape poverty, but it also means for some a legal beating and for all the threat of permanent damage. Hitting below the belt is outlawed to protect the genitals, but surely the brain deserves even more protection, by reducing the concussive power of the boxing glove, developing safer headgear, excluding the head as a target — or by banning the sport altogether. The issue is not how hazardous boxing is but whether the hazards are acceptable. The term autism refers to a cluster of conditions appearing early in childhood. All involve severe impairments in social interaction, munication, imaginative abilities, and rigid, repetitive behaviors. To be considered an autistic disorder, some of these impairments must be manifest before the age of three. The reference book used by mental health professionals to diagnose mental disorders is the Diagnostic and Statistical Manual of Mental Disorders , also known as the DSM. The 2000 edition of this reference book (the Fourth Edition Text Revision known as DSMIVTR ) places autism in a category called pervasive developmental disorders . All of these disorders are characterized by ongoing p
