drugs. I want to share with you:
1. Normal people won't get sick with certain amount of bacteria in our
system, even the real pathogens. This is why all experimental drugs will be
considered successful once the bacterial counts go below 100,000 cfu.
2. Constant presence of bacteria helps building up your immunity.
3. Trace amount of chemicals can be toxic, such as KMnO4 which can break
down to many other Mn compounds

陈年洁癖双宝妈妈。
大宝两岁九个月，去年八月开始每周两个半天上MMO。一直到现在这半年多基本上两周
病一次，每次两周。
小宝一岁，哥哥病她就跑不了。
几个礼拜以前去聚会，回来就病了。前天又聚会，于是又病了。
宝爸抱怨宝妈说，都怪你平时弄太干净所以宝宝们没有抵抗力。
其实有老大以来我就一直检讨，不愿意宝宝们生活在我的恐惧之中，自己觉得虽然离治
愈很远，但是确实改了不少。想问究竟我的生活习惯里有哪些是必须改掉的：
每天，消毒宝宝们的餐具，消毒擦所有把手（门的，冰箱的，微波炉的，等等），开关
，马桶。
每周，洗尘，用蒸汽拖把消毒木地板，消毒玩具。清洁宝宝能碰到的家具，比如沙发等。
出门的衣服一定不在家里穿，回家第一件事是洗手，然后换衣服。
宝宝的衣服都消毒。
这样真的不行吗？

methods are the same as
for acetone. Aldehydes can be removed by refluxing with KMnO4 + CaO, until
the Schiff aldehyde test is
negative, prior to distillation. Shaking with saturated K2CO3, or passaging
through a small column of activated
alumina, removes cyclic impurities. The ketone can be dried by careful
distillation (an azeotrope |
