Abstract
This research is concerned with physiological studies on the intestine of Streptopelia senegalensis aegyptiaca which is naturally infected with Cotugnia polyacantha which inhabits in the anterior part of the small intestine of the host. 11 Using the in uivo perfusion technique, glucose, Na+, C1- and K+ absorption was studied in the intestine of Streptopelia senegalensis aegyptiaca (Egyptian dove) either non-infected or infected with the cestode parasite (Cotugnia polyacantha). The doves were anaesthetized and the abdomen was opened in the midline. Temperature was maintained at 37”-38•‹Cb y the aid of 100 wtelectric lamp. A small incision was opened in the intestine just distal to the gastroduodinal junction and another incision 5 cm distal from the first one, was made. The intestine was cannulated at the two incisions. Worms were removed before beginning the experiment. 20 ml of the perfusion fluid was circulated for 20minutes with the aid of a multistaltic pump. Samples of the fluid were taken to determine glucose, Na+,Cl- and K+ . Nutrient concentrations (in mM) were 94.75 NaC1, 5 KC1, 1.2 MgC12, 1.2 CaC12, 10 NaHC03 and 5 glucose in the first perfusion fluid. NaCl and glucose were changed to (92.25 and lo), (89.75 and 15) and (87.25 and 20) respectively in the second , third and fourth perfusion fluids.
