Histomorphology of oesophagus and histochemical characterization of oesophageal mucin of the catfish Heteropneustes fossilis
The structural organization of catfish GIT consist of a short, thick-walled oesophagus connected with Jshaped stomach which terminates into three segmented intestine. The histology of gut wall, particularly oesophagus, reveals four typical layers, namely, serosa, muscularis, submucosa and mucosa. The innermost mucosal epithelium is stratified and is made up of basal cuboidal cells, intermediate...
متن کاملDerivation and Characterization of a ES-Like Cell Line from Indian Catfish Heteropneustes fossilis Blastulas
A cell line designated as HFB-ES was established from blastula stage embryos of H. fossilis (Singhi). The embryonic cells were harvested and maintained in Leibovitz's medium supplemented with 15% fetal bovine serum. The cell line had been subcultured for more than 90 passages in a period of 24 months. HFB-ES cells were able to grow at temperatures between 25 and 35°C with an optimum temperature...
متن کاملAlterations in the Corpuscles of Stannius of Euphorbia royleana Treated Catfish, Heteropneustes fossilis
Background: We aimed to evaluate effect of Euphorbia royleana exposure on histocytology of corpuscles of Stannius in fish, Heteropneustes fossilis. Methods: Fish were subjected to 2.47 mg/L and 0.618 mg/L of E. royleana for short-term and long-term exposure, respectively. Blood samples were collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, and 28 d in long-term experiment a...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
Aromatase activity in brain and ovary: seasonal variations correlated with circannual gonadal cycle in the catfish, Heteropneustes fossilis.
Seasonal variations in the aromatase activity in H. fossilis estimated by a microassay were correlated with the sex steroids, vitellogenin in and ovarian weight during circannual reproductive cycle. In the female catfish, aromatase activity was detectable in the hypothalamus throughout the year whereas in ovary only during active vitellogenesis. In the catfish, hypothalamic aromatase levels inc...
