In vitro NMR proton T1 measurements in peritoneal ascites.

The proton spin-lattice relaxation rate (1/T1) in malignant and non-malignant ascites was measured with an FT NMR spectrometer operating at 60 MHz. The mean relaxation rate in non-malignant ascites was significantly smaller than that of malignant ascites. However, the 1/T1 of malignant ascites overlaps with that of non-malignant ascites over all concentrations of total protein (TP) in samples. The 1/T1 in non-malignant ascites correlates strongly with TP, whilst the 1/T1 in malignant ascites shows only a moderate correlation. T1 measurements before and after addition of ascorbic acid (reductant) suggest that there is a small paramagnetic contribution of ions to the 1/T1 in malignant ascites. The least-squares fitting of 1/T1 versus TP for non-malignant data gives a linear relationship, and suggests that the T1 mechanism in non-malignant ascites is caused by a fast chemical exchange of water molecules between protein-bound water and free water.

Typhoid enteric perforation.

Of 306 cases of typhoid enteric perforation, 267 were reviewed retrospectively to determine prognostic indices and therapeutic options influencing outcome. The morbidity and mortality rates were 55.4 and 28.5 percent respectively, and the median duration of hospitalization was 18 days. On the basis of these findings, a prospective series of 39 patients was studied. In the preoperative period, aggressive resuscitation and antibiotic therapy with a combination of chloramphenicol, ampicillin/sulbactam and ornidazole were administered. All patients were given total parenteral nutrition to provide adequate metabolic support in the postoperative period. The morbidity and mortality rates decreased to 25 and 10 percent respectively, and the median hospitalization time was 12 days. The results of this study suggest that aggressive resuscitation and a combined antibiotic regimen in the preoperative period, selected operative procedure and metabolic support decrease the morbidity and mortality of typhoid enteric perforation.
