TOPIC: ARGUMENT51 - The following appeared in a medical newsletter.

"Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. This hypothesis has now been proved by preliminary results of a study of two groups of patients. The first group of patients, all being treated for muscle injuries by Dr. Newland, a doctor who specializes in sports medicine, took antibiotics regularly throughout their treatment. Their recuperation time was, on average, 40 percent quicker than typically expected. Patients in the second group, all being treated by Dr. Alton, a general physician, were given sugar pills, although the patients believed they were taking antibiotics. Their average recuperation time was not significantly reduced. Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment."

It is apparently that the experiment taken is in lack of sufficient effective information. First, there is no further description of the situations of the two groups of patients, such as whether the injuries they suffered are of the same extent, whether they are in the same physical fitness while this may have strong relations with the recover process. The sex composition of the two groups, and the  age structure，and so on. All these factors may alter the results impressively. Unfortunately, these are not contained in the essay above.

Additionally, the researchers failed to exclude other factors that may cause the difference of the recovery process of the two groups. Maybe the long suspicion that secondary infections keep the patients from healing quickly reveals their considerations of other factors. This may be taken care of seriously or some other factors.

Furthermore, the conclusion is lack of logic. Even if we have convicted that biotic may do good to the rehabilitation of severe muscle strain, we cannot say that all the patients suffered form muscle strain should be advised to take antibiotics. Also, now we know that antibiotics may accumulate in human's body and eventually lead to an antibody production which makes the body has no resistance to biotic any more. There may be some alternatives. Sometimes biotic maybe do harm to some patients recovery for the experiment didn't investigate the negative influence of biotic.

In conclusion, the author's view still needs further supports.
