NO (Nitric Oxide) is an inorganic compound composed of nitrogen and oxygen, NO is also produced in various places on various types of mammalian cells. NO as a radical compound is important in mediating physiological and pathological events in mammals including humans [1].GEJ (gastroesophageal junction) is a transition zone between the surface of esophagus which is covered by stratified squamous epithelium to the gastric mucosa which consists of simple columnar epithelium (z-line), where circular muscle of esophagus fuse with oblique muscle and lipid layer of the gaster. At the lower part of GEJ, there is the lower esophageal sphincter (LES) that not only allow food to move into stomach and works as an exit passage of the gas, but also inhibit reflux of any substances that potentially can cause harm to the esophagus [2].Petersson et al, found that chronic exposure to cytotoxic levels of NO can cause inflammation, intestinal metaplasia and neoplasia. Although it is known that gastric acid, pepsin and bile acids can cause adenocarcinoma of distal esophagus and GEJ, NO exposure and nitrosative stress role in this phenomenon is yet to be fully understood and further study is needed [3].The purpose of this was to identify and compare the histopathological changes occurring in GEJ in relation to administration of physiological concentration of nitrate dissolved in HCl and ascorbic acid. As such, the animal model used in this study can be used to study and represent the changes microscopically, because obtaining a full thickness biopsy from a human subject can be difficult to perform.

On April 2016, Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Bogor Agricultural University (VTH FKH IPB) received 4 cases of femoral fractures in cats caused by trauma. Two cats suffered oblique diaphysis fracture femoral, one cat suffered comminuted diaphysis fracture femoral, and one cat suffered epiphyseal fracture femoral (column femoral and trochanter major). All cats were treated by open surgery using intramedullary pins (Steinmann) and cerclage wires (Kirschner). Fracture recovery went without complication and all cats were able to move their feet one week after surgery.

Bahan alam yang dapat menghambat spermatogenesis merupakan suatu alternatif untuk kontrasepsi pria. Penelitian ini bertujuan mengevaluasi formulasi optimum berbasis biji jarak pagar dan buah pare yang dapat menginhibisi spermatogenesis. Bahan sampel dimaserasi alkohol 70% untuk memperoleh ekstrak kasar. Ekstrak diujikan pada tikus Wistar jantan dewasa sebanyak 30 ekor dan dibagi menjadi enam kelompok secara acak (n=5 ekor). Kelompok I sebagai kontrol memperoleh pelarut akuades; kelompok II dan III secara berurutan memperoleh ekstrak biji jarak dan pare dengan dosis 50 mg/kgBB. Tiga kelompok lainnya, yaitu IV, V, dan VI memperoleh formulasi gabungan dengan rasio ekstrak biji jarak pagar dan pare 1:3, 3:1 serta 1:1, secara berurutan. Perlakuan diberikan per oral satu hari sekali selama 48 hari sesuai dengan siklus spermatogenesis. Pada akhir perlakuan, pemeriksaan sperma untuk konsentrasi dan kualitasnya serta bobot testis. Hasil uji rendemen ekstrak biji jarak pagar dan buah pare secara berurutan sebesar 6.11 % dan 3.32 %. Senyawa fitokimia yang terdapat pada ekstrak pare dan biji jarak pagar antara lain, alkaloid, fenol, flavonoid, tanin, saponin, triterpenoid, dan steroid. Efek ekstrak terhadap bobot testis dan konsentrasi sperma tidak ada perbedaan yang nyata antar kelompok (ANOVA P >0.05) sedangkan untuk kualitas motilitas sperma ada kecenderungan menurun pada formulasi ekstrak biji jarak dan buah pare (1:3).
