All things considered, it seems reasonable to accept that injecting a small dosage of drugs in animals is acceptable as it could help and improve to find cures for the illnesses. How can I improve? what words shall I remove?
I'd omit "to accept" and "as" and "and improve to" and put a period after "acceptable." I'd change "it" to "This practice"
What do you get?
I don't get it...
You don't get what? I told you exactly how to fix this sentence!
If you rewrite it all, as I told you above, I'll check it for you.

You followed some of my directions but not all.
Re-do.
What do u mean by put a period after acceptable?
Exactly that. Make the first sentence stop there and start a new sentence.
Starting a new sentence will require some re-wording, which I've also told you how to do.
