Vawiin hian damdawi lam thil thar leh pawimawh ber pakhat kan sawi dawn a ni. Chu chu Pharmacogenomics a ni.
A awlsam zawngin Pharmacogenomics chu eng nge ni?
He thumal hi a sei deuh a, a harsa hmel hle a ni lawm ni? Mahse, i ti chhe vek ang u. Tichuan a awlsam khawp mai. Thumal pahnih dahkhawm atanga siam a ni.
1. Pharmacology: Hei hian damdawi lam zirna a kawk a ni . Chu chu damdawi hman dan te, taksa chunga a tih dan te, a nghawng dan te a ni.
2. Genomics: Hei hian genes leh an hnathawh dan zirchianna a kawk a ni .
Chuvangin heng pahnih hi an inzawm khawm chuan Pharmacogenomics chu kan genes te hian kan damdawi ei te a chhan dan zirchianna a ni.

Hei hi damdawi lam field thar "Precision Medicine" tih hming pu a ni. "Damdawi bik" tihna a ni. Mi zawng zawng hnenah damdawi inang pe lovin, i genes, i nunphung, leh i chenna boruak ang chi thilte a ngaihtuah a, i tana ṭha bik enkawlna a thlang zawk a ni Store-a kal a, mi zawng zawng tana kawr lian inang lei ang maiin han ngaihtuah teh, puan siamtu hnena kal a, i tehfung anga siam kawr siamsak ai chuan. Hei pawh hi chutiang bawk chu a ni.
Tunah hian he method hi natna leh damdawi tlemte tan chauh hman a ni. Entirnan, he technology hi HIV, cancer chi thenkhat, depression, leh lung natna damdawi thenkhat tan te hman a ni. Mahse he field hi a thang chak hle a ni. Researcher-te chuan hun rei lote chhungin pharmacogenomics hian doctor-te chu natna tlanglawn ber berte tan pawh damdawi tha ber thlang turin a pui dawn niin an ngai.
Engtin nge kan genes hian damdawi a nghawng?
Hei hi hrethiam tur chuan kan taksaah hian genes te hian eng nge an tih tih kan en hmasak a ngai a ni. Kan genes hi kan taksa siam leh hman dan tur zirtirna bu kimchang tak angin han ngaihtuah teh. Kan taksa chhunga cell te hian he instruction manual-a thupek angin hna an thawk a.
Heng thupekte nena kan tih tur ber chu enzymes a ni.Protein molecule enzyme an tih siam. Enzyme te hi kan taksaa hnathawk te te ang mai an ni. Heng hnathawkte hian hna sang tam tak an nei a. Chung hna pawimawh ber pakhat chu kan damdawi eite tihchhiat, a nih loh leh tihdanglam (metabolize) hi a ni.
Pill i ei kha han mitthla teh. Natna tidam turin a kal nghal lo. Chu pill chu kan taksa chhunga factory-te (entir nan, thin)-ah a kal hmasa tur a ni a, chutah chuan chuta hnathawkte (i.e. enzymes) chuan an tichhia a, an tichhia a, taksa hman theih turin an siam a ngai a ni.
Tunah chuan han ngaihtuah teh, mi thenkhat genes inthlak danglamna avanga heng enzyme te hian hna an thawk tha lo a nih chuan eng nge thleng ang?
- Enzyme te hian hna a thawk rang lutuk a nih chuan: Damdawi i ei kha, a hip luh hma leh natna a nghawng hmain, a chhe vek a, taksa atangin a chhuak nghal vat thin. Tichuan normal dose chu i tan a tawk lo. Damdawi hian hna a thawk lo ang maiin a hria ang.

Chutiang chuan kan gene-a inthlak danglamna tenau te pawhin kan damdawi eiah nghawng lian tak a nei thei a ni.
Heng genetic changes te hi eng test nge hman thin?
Hei hi pharmacogenomic test kan ti a . Hei hi genetic test a ni bawk. I DNA a en a, damdawi pakhat a chhiat dan tichhe thei gene bik pakhat emaw, a aia tam emaw a inthlak danglamna eng pawh a zawng chhuak thin.
He test ah hian thisen sample emaw buccal swab emaw hman a ni tlangpui . A awlsam khawp mai. I doctor chuan he sample hi laboratory-ah a thawn thin. Chutah chuan technician-te chuan i DNA chu a kaihhnawih gene-a inthlak danglamna a awm leh awm loh an enfiah thin.
I doctor chuan i damdawi lam dinhmun leh damdawi chi hrang hrang an pek tur che a zirin eng gene nge test tur tih a rel ang.
Eng dinhmunah nge pharmacogenomic test neih a ngai?
Tunah hian he test hi natna tin emaw damdawi zawng zawng emaw atan tih a ni lo. Mahse, i doctor chuan natna bik thenkhat i enkawl hunah he test hi a rawt thei ang. Entirna thenkhat han en ila. He thu hi chiang zawka hriatthiam theih nan a hnuaia table hi en la.

Hetiang hmanrua hi eng nge a thatna?
Pharmacogenomics field a lo thang zel chuan hlawkna nasa tak kan nei dawn a ni.
- Enkawlna him zawk: Doctor-te chuan mi ṭhenkhatah side effect na tak emaw, overdose emaw thlen thei damdawi an hmuchhuak thei a, chuvangin chu damdawi chu an pumpelh thei a, damdawi him ber an pe thei che a ni
- Enkawlna tha leh senso tihtlem: Ngai teh, natna pakhat atan damdawi 3-4 i thlak a ngai a, a tawpah chuan damdawi dik tak i zawng chhuak a ngai a ni. Chumi hma chuan i hun te, i sum leh pai te, i thawhrimna te chu a khawhral a ni. Tin, natna a dam hma loh chuan i tuar bawk. Mahse he test hian damdawi pek hmasak ber hmangin natna chu a tidam thei a nih chuan , chu chu engtiang chiahin nge a ropui ang?
- Targeted drug development: Natna thenkhat hi gene bik inthlak danglamna avanga lo awm a ni. Chuvangin zirchiangtute chuan chu gene inthlak danglamna chu direct-a target thei damdawi thar an siam thei a ni . Hei hi cancer ang chi natna enkawlnaah a pawimawh hle.
Mahse hei hian a tawp chin a nei...
Hetiang method hi eng ang pawhin tha mahse engkim a chinfel vek lo. Damdawi a thlan hian Doctor chuan genes chauh a ngaihtuah lo. Thil dang ngaihtuah tur tam tak a awm bawk.
A pawimawh ber chu, i genes te hi thawnthua tel ve chauh a ni. Damdawi hnathawh dan tidanglam thei thil dang tam tak a awm bawk.
Doctor pawhin thil dang a ngaihtuah tur a ni a, chungte chu:
- Tuna i ei mek damdawi dangte: Damdawi i ei mek chu condition pakhat leh condition dang tan chuan i taksa chu a chhe thei khawpin a nghawng thei a ni.
- Damdawi lam harsatna dang i neihte: Entirnan, thin emaw kal (kidney) lama harsatna i neih chuan damdawi taksa atanga a paih chhuah dan a nghawng thei a ni.
- I nunphung: I ei leh in te, exercise i tih leh tih loh te, meizuk leh zu in ang chi thil te pawhin i damdawi a chhiat dan a nghawng thei a ni.
Chu bâkah, harsatna dang engemaw zât a awm bawk:
- Hman senso: Heng genetic test man hi a tlahniam zauh zauh nachungin, mi thenkhat tan chuan a man to lutuk a la ni thei.
- Inccessibility: Heng test neihna tur facility hi Sri Lanka hmun tinah a la awm lo. Hmun tlemteah chauh an awm.
Mahse, he field "Precision Medicine" hi a lo thang chak hle a ni. Hemi chungchanga zawhna i neih chuan i doctor nen inbiakna neih hlau suh . I dinhmun atana hetiang test neih hian hlawkna a awm em tih zawt rawh.
