why rats?

baru2 ni practical histo ngn dr.zenab...study slide penis,scrotum and epididymis...bile tgk slide penis,aku mule terbayang,aik,xkn cut section die besar ni je kot...diameter die dlm 0.5cm..so,gile kecik zakar manusia an??and aku sgt pelik and akhirnye aku bertanya..

'doctor,is this human penis?'tanpa malu aku tny cz aku mmg sgt curious..

'no no..this is rat's penis...and the slide of testis is rodents'...dgn tenang beliau menjwab...

'act all the scientis and all the experiments to see slide of the organ we use the rats because rat body function and organ is similar 95% with the human.'

hahaha..baru la logik..haii..asal la selame ni aku x taw an...dah tu xnk tny lak tu...myb org len dah taw tp xpela..at least aku dah taw dah..patotla before2 ni,slide liver,slide tounge,slide stomach semua,kalo tgk blk cut section die kecik je...rupenye organ tikus...mmg kebanyakannye tikus...kenape tikus ek?nape die x gune je mamalia lain yg lagi besar mcm kuda ke,lembu ke,anjing ke,kucing ke an..aku still pelik cz binatang ni lg besar and mesti lg same structure ngn human body an..

mule2 aku fikir pasal tikus ni membiak bpk cepat and bpk bnyk..ok betul tekaan aku...tp untuk aku disebabkn tikus ni dah la bnyk gile spesis die kat bumi ni,penyakit lagi la bnyk yg die bwk..tu dlm pemikiran aku..tp yg sebetulnye,bnyknye jumlah tikus ni ade hikmah die...pasal die breed laju la scientis dulu and sekarang gune die dlm buat mcm2 jenis research..ooo..camtu...thnx Dr.Zenab..i owe u for the great explanation.

so,blk je umah aku pun usha2 la link2 yg tertentu and aku terbukak satu blog budak medic ni yg rupenye curious gak cam ak..the rats are used because of certain reason:

1. they reproduce readily and raqpidly so mmg bnykla sekali nk wat experiment.
2. easy to keep
3.there are many disease models developed for rats: obese rats, arthritic rats, schistofrenic rats and a hundred of other
4. it is easy to take measurments from rats buy chopping their tail peice by piece and see development of pathology

in other words la an,tubuh badan kite ni hampir 95% same ngn mamalia bernama tikus

melainkan bentuk tubuh kite dan otak kite yg mampu berfikir.

dulu kat matrik pun aku igt lg ade experiment disection tp x igt nk investigate ape time tu,haaa..bedah tikus la..dah mati la...so bayangkan la bnyk x bnyk tikus makmal ni...kalo bdk sains hayat kat matrik dulu ade 2000 org,sekor tikus kongsi 2 org,gile arh,setahun kerajaan

kene beli average 1000 tikus makmal setahun...hmmm2..bnyk gile la tikus ni breed rupenye..

sebijik time matrik dulu.

camni la kene disect.

ape2 pun,kalo x pasal tikus2 ni,jgn harap la doktor2 dulu and saintis old school dulu leh jmp penyakit,function cell ini and itu,gene manusia yg variasinye berlainan,sistem pemakanan manusia and macam2 lg...hoho..terime kasih encik tikus.

sprague dawley rat

common gune die ni la dlm medical research

yg geli2 sikit ni,

hairless rat

biase gune nak kaji immune system and genetic disease

yg hot semacam ni,

zucker rat

tikus yg digunakan untuk kaji sistem pemakanan kite

kaji bape carbohydrate,lipid,protein and metabolism lain yg diperlukan tubuh kite.
