HISTOMORFOLOGI DAN DISTRIBUSI KARBOHIDRAT NETRAL PADA ESOFAGUS DAN PROVENTRIKULUS AYAM HUTAN MERAH (GALLUS GALLUS) ASAL PULAU TIMOR

Abstract

Red jungle fowl is one of the endemic animals in the island of Timor which has a decline in population. This study aimed to determine the histological structure and distribution of neutral carbohydrates in the esophagus and proventriculus of red jungle fowl (Gallus gallus). The main samples used in this study were three samples esophageal tissue and proventriculus. Chickens were killed by cervical dislocation to collection esophageal and proventricular organs those fixed in 10% formalin. The histolomorphology structures were identified by using hematoxylin-eosin (HE) staining and neutral carbohydrate distribution was identified by using Periodic Acid Schiff (PAS) staining. The results showed that esophageal histolomorphology structure consisted of four layers, namely tunica mucosal, tunica submucosal, tunica muscularis and tunica adventitia. Proventricular histolomorphology structure consisted of four layers, namely tunica mucosal, tunica submucosal, tunica muscularis and tunica serous. Neutral carbohydrate distribution were found in the esophageal glands showed strong positive reaction while epithelial lamina and loose connective tissue in the lamina propria showed weak positive reaction and proventriculus showed strong positive reactions in cells lining the epithelium and cavity of simple tubular glandular.
