Glucagon and infusion cholangiography.

It has been previously suggested that glucagon improves the bile duct and gall-bladder opacification obtained by infusion cholangiography. One hundred and ninety consecutive patients referred for intravenous cholangiography were entered into a double-blind study designed to see if glucagon would in fact significantly improve bile duct opacification. All patients received a one hour intravenous infusion of iotroxamide at a rate of 3.15 mg/kg body weight/min. Glucagon did not enhance bile duct opacification, the mean post-injection scores for the two groups being 2.47 +/- 1.11 and 2.29 +/- 1.15 respectively. On the basis of the present study we cannot recommend the routine use of glucagon following infusion cholangiography.

Recovery of coliphages from wastewater effluents and polluted lake water by the magnetite-organic flocculation method.

A magnetite-organic flocculation method was developed for the concentration of coliphages from wastewater effluents and polluted lake water. A high percent (68 to 100%) recovery of coliphages from sewage effluents was achieved by this procedure. Coliphage recovery from Lake Alice, a sewage-contaminated lake, showed phage concentrations ranging from 2.3 X 10(2) to 1.9 X 10(3) plaque-forming units per liter. This method is simple and inexpensive and may be carried out under field conditions.

Drip infusion cholangiography using iotroxamide. Double blind comparison with ioglycamide.

A double blind clinical trial was carried out in 200 unselected patients to compare the efficacy and tolerance of ioglycamide and iotroxamide as contrast media for intravenous cholangiography. The two agents were administered by slow infusion at a rate of 2.6 mumoles/kg bodyweight/minute for one hour. Radiological opacification of the bile duct was assessed independently by two radiologists. In patients with serum bilirubin levels of less than 34 mumoles/litre visualization of the bile duct was significantly better with iotroxamide than with ioglycamide (P < 0.001). Toxic side effects were observed in 8% of patients receiving ioglycamide and in only 3% of the patients given iotroxamide.
