来自主题: Macromolecules版 - How to do drug uptaking experiments
Recently I am doing drug uptaking experiments. I put the swollen hydrogels
into the drug solution. At different time intervals I take out some drug
solution, and dilute them to detect the concentration by HPLC. First I thought
this way is good to determine the drug uptaking kinetics. However the results
are not good because the concentration of the solution didn't change very
much.
Can you tell me how to determine the drug uptaking?
Thank you very much.

I would like to do that too,because some peoples tell me that by this way more
drug will be uptaken.
Do you think both water and drug diffusing rates are same?
If not, water is faster, the concentration of surrounding solution will
increase. How can you get the uptaking kinetics by determing the concentration
of surrounding solution?
What kind of method I can use to determine amount of drug uptaking except to
release?

What is the weight ratio of the drug solution to the swollen hydrogel? If this
ratio is too high, you should expect that drug drop in the drug solution
would be very small. How about use less drug solution but high drug
concentration? BTW, why do you want to do this kind of drug uptaking? at first
, I though it's about drug uptaking by cells!

It is necessary to diagnose you accurately by ordering thyroid uptake and
scan. There are a lot of etiologies which can lead to hyperthyroidism, and
your doctor wants to find it out the reason which cause you have overactive
thyroid gland.
After your doctor can find more clues or hints from the scan,he or she can
treat you more appropriately.

I want to check experienced parents how you feed your toddlers (2-3 years
old) with sufficient amount of milk every day? I usually feed him milk 3
times a day, morning, afternoon and evening before going to bed.
It is fine until now he is potty training. I am trying to reduce the
urinating habit during night sleep, so don't want to offer him the milk
before going to bed. Then it is difficult to maintain the same amount of
milk uptake.
Want to check other parents how you solve this? Thanks.

上来问问各位生物同学,实在没有办法了。最近试验发现小鼠皮下注射后一些lipids能
很好的留在淋巴结里,主要是macrophage的uptake,初步试验似乎是albumin和这些
lipids高度亲和,将它们带至淋巴结,但是albumin是如何转运这些lipids到
macrophage的呢?如果是nonspecific cell membrane insertion, 似乎淋巴结里其他
的细胞(B,T,Cells)因该也会分一杯羹。我的问题是:一般说来,lipids或者是
fatty acids是如何被lymph node macrophage 捕获的?有没有cell-surface receptor
在macrophage细胞表面?多谢,我不是学生物的。

是有少部分DC in lymph nodes 也uptake,但大部分都是macrophage,皮下注射2小时
后淋巴结里就有大量的lipids,所以主要可能还是lymph node draining而不是兰格汉
DC transfer.

谢谢回复!
你说测血液、肝肾里面的细菌含量,意思是可以检测到活的还是死的细菌?还是细菌被
降解的代谢产物?
另外一个问题:细菌被巨噬细胞uptake以后会降解,这个降解之后是不是连细菌的DNA
都没有了?

终于得闲可以坐下来写点东西了,喘口气先。
首先,这篇评论是目前我看到的写得相对最中肯的一片,原因很简单,作者确实是这个

If you are an American diabetic, your physician will never tell you that
