Abstract


Penelitian ini bertujuan mengetahui gambaran histologis timus pada ayam kampung (Gallus gallus domesticus). Hewan yang digunakan adalah ayam kampung (Gallus gallus domesticus) berumur 1 bulan, 2 bulan dan 3 bulan masing-masing tiga ekor. Jaringan timus masing-masing hewan diambil dan diproses secara mikroteknik dengan pewarnaan hemaktosilin-eosin (HE), kemudian diamati di bawah mikroskop elektrik. Hasil penelitian menunjukkan adanya perbedaan struktur timus dari ketiga umur tersebut. Bagian korteks pada umur 2 bulan tampak lebih tebal dibandingkan dengan ayam kampung umur 1 bulan dan 3 bulan. Diameter medula paling panjang pada ayam kampung umur 3 bulan dibandingkan dengan umur 1 bulan dan 2 bulan. Sebaran badan Hassal’s mengalami peningkatan pada setiap tingkatan umur. Kesimpulan dari penelitian ini adalah semakin bertambahnya umur maka ketebalan korteks semakin mengalami penurunan dan diameter medula semakin panjang pada umur 3 bulan.

The aim of this research was to determine about histology finding of local chicken (Gallus gallusdomesticus) thymus at different age. Animal used were local chicken (Gallus gallusdomesticus) age 1 month, 2 months, and 3 months, each were three chicken hematoxylin-eosin (HE) stain, then observed under electric microscope. This result showed there were differences in thymus histology structure among three age. Cortex thickness has increased at age 2 months and then has decreased at age 3 months. Diameter of the medulla has longest on local chicken age 3 month then followed age 2 month and 1 month. Distribusion of Hassal’s bodies has increased every levels age. The conclusion of this study is the increasing age of then the cortex thickness has decreased at 3 months meanwhile  diameter of the medulla getting longer.
