51.抗生素与肌肉拉伤二次感染
   The author recommend that all the patients suffering from muscle strain should be treated with antibiotics so that they can aviod secondary infection, thus their recovery can be shortened. To support this conclusion, the author points out the preliminary results of a study in which two groups of patients with muscle strain were treated by two doctors.The first group following the advice of Dr.Newland who is majored on sports medicine,by taking antibiotics during the recuperation,while the other group treated by Dr.Alton,a physician,taking sugar pills at the same time,without knowing that what they are taking are sugar pills rather than antibiotics.The result came that the first group's recovery time was reduced by 40%,but the second group couldnot see apparent decline.However,this recommendation is based on spicious asumptions which render it entire unconvincing.
    First of all, this experiment upon which the conclusion are drawn rely on the dubious assumption that all this patients are affected by secondery infection.To justify this conclusion the author should raise suffice evidence that all the patients in two group are already in this very condition.Lacking this significant evidence, the final conclusion that the antibiots helf recovery simply by the statistics revealed from the study is entirely unconvincing.
    Secondly,the controlled experiments have many fallacies.The experiment's results are reliable if the number of experimental subjects is statistically significant,and if the the subjests are of the same conditions to begin with.But in the newsletter it does not mention the number of each group,whether it is statistically significant and to which extend they are suffering from muscle strain. Perhaps the patients in the first group are less severe than the second one.Thus the quiker recovery of the first group cannot be conclude to the use of antibiotics.
    Thirdly, the article assumes that excepr from what they are taking during the period,they recieved the same treatment in their recuputation. Due to the two doctors specialized in different majors,it is possible that they are conducted different treatments with the seperate group from their own experience.Without ruling out this possibilities,it might be folly to follow the author's recommendation.
    Finally, even if the author can substantiate the foregoing assumptios,I remain unconvinced that whether the antibiots will be helpful to all these patients.Perhaps antibiotics will have side effect or cause allergy to certain people,or perhaps it will just be effective to the severe patients. Lacking such evidence, the conclusion is untenable.
    In sum, as it stands it is a qustionable recommendation.To support the argument,I would need more information about the effectiveness of the doctors' treatment to ensure the reduction of recovery time is the result of antibiotics.To better assess the argument,the author must provide more evidence of the in-depth research of antibiotics to find out whether if will cause any side effect.
