people pay attention to in the process of poisoning - powerzi/adapter GitHub Wiki
Don't rough not expatiate a migraine headache
The rye sometimes parasitic called a ergot of mold. There is no lack of food in the history of the mould contamination of rye and poisoning records. Some people will experience wonderful acid, some are bad luck meet limbs. This thing slowly has strong superstition color. Do not know from when to begin, people pay attention to in the process of poisoning, slant headache symptom be mitigated. Study medicine found that from this mould separated to Ergotamine (Ergotamine) as a representative of ergot alkaloids is the major cause of the phenomenon. But believed that by taking ergotamine treatment of migraine headache is obviously too hasty, especially for a migraine headache this very complicated disease in.
First of all, from the emotional changes to tinnitus, from the view of disappear to pulsatile pain, migraine symptoms abnormal heavy and complicated. How to through the change of symptoms to judge "treatment effect" is first of all to solve the problem. In addition, a migraine headache pain is not stable, the same time attack in pain will have wave motion, different times the strength of the attack is different also. In this case to determine the effect of external factors more difficult. The most important thing is, slant headache all the symptoms are obvious self-limited, treat died will turn out. 1:http://powerzi.com/12v-2a-desktop-type-ac-dc-adapter-p-30.html 12V2A AC DC Adapter
So, if only by taking ergotamine and pain relief that the time has relationship, that can treat migraine headaches, will come to wrong and even funny conclusion - don't say eat ergotamine, even eat weight, 4 to 72 hours later, the pain will disappear. As long as don't abandon yourself, try a lifetime are no problem. But we can believed that weight is beneficial to the improvement of the headache, then eat a lifetime weight? Obviously not.
Even taking ergotamine indeed to have a headache relief, or is not sufficient to prove the headache because ergotamine role. Perhaps in the process of disease itself on the mend, maybe drugs to patients had an impact on the way, and maybe other non-drug sex what reason also perhaps. For instance, may be because saw a girl are extremely, let a person temporarily not in pain, Or is everyone together, to alleviate pain easy; Or, patients psychological change on good condition.
In other words, these patients living environment, clothing, medicine and so on are all the same way, including to give them an injection - because you do not know who use drugs, what is for all patients, also won't have difference. And injection of saline, slant headache symptoms did not change; Injection ergotamine, relieving symptoms.
In all other related factors are unchanged, a factor change, bring different results. This shows that led to this result change, this is the changes of factors, not the other way. Thus do we can think of, in this experiment lead to symptoms, is the only difference between the two groups: ergotamine?
This reasoning mode, is the formal logic to determine the causal difference method. In this study using difference method lies in how to design the experiment, to ensure that in addition to ergot besides, two group of related factors are the same.
The influence of these two factors, in addition to the one is ergotamine, is a physiological saline, other conditions are the same. But the two groups of patients is the "same"? If they are not the same, so lead to two groups of patients before and after treatment effect in the cause of the discrepancy is likely to be the difference between person and person.
Obviously, people is really different.
Based on this principle, all patients with migraine headache of time itself, although each one headache time do differ, some 4 hours, some seven hours, some 24 hours, some 72 hours, etc., etc., these different time value, will eventually show a certain rule. When we view it from this general crowd drawn at random enough two group of people, then statistical once, will find that these two groups of people have a headache time represented by the law, and the law of total population is the same. That is to say, of the two laws, is the same.
In the same way, as long as more than enough, the two groups not only in a consistent, time in pain intensity of symptoms, many aspects, such as is the same. So, as long as we ensure that population is enough big, can guarantee them as a whole, enough "same". And based on this, in the experiments that the establishment of the two large quantity crowd consisting of the treatment group was, indeed, "the same". So, maybe ergot in each individual body produce effect may be different, but the drug to "same" crowd role, is the same.
