| Popis: | Gastro-respiratory tract of the loach,Lepidocephalichthys guntea has been studied with special reference to the nature of its mucus secreting epithelia. The mucous cells are strongly PAS-positive and their number per unit area (mm2) in the mucosal layers of oesophagus, intestinal bulb, intestine and rectum are 733, 531, 223 and 540, respectively. The air-breathing segment of the gut is completely devoid of neutral mucosubstances, and there is a predominance of acidic mucosubstances over the neutral ones throughout the digestive tube. The air-blood pathway of the accessory respiratory organ is about 2.6 μm which is higher than the values of air-breathing organs of other fishes. |
