<div>Background: Vagal indigestion in cattle is an abdominal disorder resulting from mechanical or functional obstruction of the fore stomach and/or abomasum outflow. Prognosis is usually poor except in late pregnancy indigestion. A Holstein- Friesian cow in late pregnancy was presented to the Veterinary Clinical Complex with the complaint of hyporexia, papple-shaped abdomen, dyschezia and voidance of pellety or dark scanty and greenish pasty dung for 8 days.&nbsp; 
 
Methods: Physical examination revealed papple-shaped abdomen. Rectal examination revealed L-shaped rumen and dilated intestinal loops. Haemato-biochemical analysis revealed neutrophilia, hyperglobulinemia, hypocalcaemia and hypokalemia. Blood gas analysis revealed no alterations. Ultrasonogram revealed normal architecture and motility of abomasum and absence of impaction. 
 
Result: Type II vagal digestion was identified as a cause in association with functional (adynamic) ileus which was due to with hypokalemic alkalosis and hypocalcaemia. The case responded to the treatment with cholinergic drugs, fluid therapy, antibiotics, antiinflammatory drugs and oral electrolytes.</div>

Type II Vagal Indigestion and Adynamic Ileus in a Pregnant Cow with Haemato-biochemical and Blood Gas Analysis

The present study was conducted to recognize by part, the cardiovascular events of the nasopharyngeal reflex, through electrocardiographic interpretations. ECG patterns were traced in twelve clinically normal and healthy New Zealand White rabbits of both sexes, weighing between 2-3 kg and aged between 1-3 years with inhalant irritants. Immediately after induction of formaldehyde vapour, the heart rate fell by 69% from a mean of 192 &plusmn; 7.310 bpm to 60 &plusmn; 1.296 bpm, whereas exposure with cigarette smoke caused a fall in heart rate by 74% from a mean of 205 &plusmn; 9.605 bpm to 53 &plusmn; 3.065 bpm. With both irritants, P wave becomes smaller and totally disappeared, indicating an increased vagal activity inducing a sinoatrial node arrest. The amplitude of QRS complex also significantly decreased; and so did the duration of P wave and PR interval, presumably due to junctional escape. T wave duration decreased with slow ventricular repolarization. Bradycardia was also evident with increased QT interval. However, there was no change in QRS complex or ventricular depolarization, mediated perhaps via compensatory sympathetic influence on the ventricular myocardium. The study demonstrates that both formaldehyde and cigarette smoke provoked a similar protective response of rabbits against noxious fumes.
