Morphological Characteristics of the Stomach of the Swamp Buffalo (Bubalus Bubalis)

The ability of swamp buffaloes for adaptation to swampland was suggested to be supported by their digestive system efficiency including absorption one. This research was done to obtain scientific explanation about digestive efficiency of swamp buffalo by investigating swamp buffalo stomach morphologically. Six stomachs were obtained at slaughterhouse from 2.5-3 years old healthy male swamp buffaloes. Every part of the stomach includes nonglanduler stomach (forestomach: rumen, reticulum, and omasum) and glanduler stomach (abomasum) was taken for measuring length, width, and weight organs. Then all of samples from each part of stomach were prepared for morphological observation. The data were analyzed descriptively. Stomach of swamp buffalo had morphological peculiarities, such as: mucosa surface of rumen, reticulum, and omasum has black color, and there is variation of ruminal papillae of swamp buffalo, including branching. Special characteristics of swamp buffalo stomach is estimated as supporting morphological factors for increasing digestive efficiency to survive in swampland

Distribusi Saraf Pada Epitel Olfaktorius Kalong Kapatuk (Pteropus Vampyrus) Dan Lasiwen Deignan (Myotis Horsfieldii) Berdasarkan Ekspresi Neuron-specific Enolase (Nse)

Kelelawar merupakan salah satu keanekaragaman dan kekayaan satwa di Indonesia. Adanya keanekaragaman jenis makanan maupun habitat kelelawar menyebabkan terjadinya perbedaan dalam mencari dan cara makan dari berbagai jenis kelelawar. Keterkaitan antara struktur indra penciuman dengan jenis dan cara makan kelelawar sangat menarik untuk dieksplorasi, karena sampai saat ini sangat sedikit data mengenai hal tersebut. Penelitian ini menggunakan 3 ekor kalong betina dewasa dan 3 ekor lasiwen betina dewasa, sebagai sampel. Hidung sebagai sampel, kemudian dibuat preparat histologi dengan metode parafin dan pewarnaan imunohistokimia terhadap ekspresi NSE. Hasil pewarnaan imunohistokimia menunjukkan bahwa imunoreaktivitas NSE pada lasiwen terindentifikasi dalam epitel olfaktorius di kedua sisi septum nasalis, konka dorsalis dan beberapa fila olfaktoria. Pada kalong tidak terindentifikasi adanya imunoreaktivitas NSE
