	Dear Thi'm Die^~m Quy`nh,

	Thank you for your explanation.
	:-) Your language is not one of present time. I feel difficult for 
those like anh Tie^'n to totally understand all what you wrote.
	I will correct/add vietnamese, modern medical terms for your 
posting.:-)
	I hope you will accept it. Thank you!
	I also have some questions for discussion that were inserted in your 
text.
	CB.
