dark skin colour

assalamualaikum...

just short entry..

setiap ape yg Allah ciptakan ade hikmahnye...

sape kate owg kulit gelap cam aku ni x cantek?!

oppss!

aku bukn nk kate aku ni cantek...

alhamdulillah....

aku sedar diri...

manusia tu kn sebaik-baik kejadian..

nk share skit...

smlm tetibe aku 'ter'rajin nk bace lecture notes..

genetic & acquired abnormalities of the bones...

ape kaitan dark skin colour dgn abnomalities in bones ni?!

meh sni aku tergkn skit...

one of the causes of acquired bone diseases is abnormal mineral homeostasis.

toksah pening2 kepala!

bile ckp pasal mineral,mineral yg terlibat dlm osteogenesis(formation of bone) of course calcium n phosphate! sbb both mineral needed for mineralization..

if either calcium or phosphate is low,then mineralization is impaired!

senang citer,dua2 kene ade r!

For absorption of both mineral,vitamin D is needed!

act as a substrate for the renal hydroxylase...

wink3~~****

dh start pening dh...hehehe

stakat ni phm??

k,ape yg aku nk teknkn kat sni ialah deficiency of vitamin D!

kite kn bley dpt vitamin D from dietary or sunlight!

ha!kite dh mule nk kaitkn dark skin colour dgn bone abnormalities..

Ade disadvantage gak org kulit gelap ni,

bile expose to sunlight,kulit kite akn produce melanin for protection from uv light..

pigment yg terhasil tuh akn limitkn kulit kite dpd dpt vitamin D....

uv light plak function die tuk activate kn vitamin D kat skin kite,

so,bile kurg uv rays, Vit D pun x dpt nk activate....

So,owg kulit gelap ni prone to get osteomalacia=excess of unmineralized osteoid bone..

tulg kite akn weak n easily fractures..

adult=osteomalacia

children=rickets

But!

ade advantage gak org kulit gelap ni..

kn tad aku de mention pasal melanin production kn..

bgus sbnrnye tuk prevent uv light...

can prevent skin cancer!!

Kalo natural sources tuk vitamin D,kite bley dpt dpd fish liver oil,eggs,tuna..etc...

so,amalkn pemakann yg sihat ye!

u r what u eat!!
