A new method for the determination of urinary formiminoglutamic acid (FIGLU) using conventional electrophoresis at 200 to 500 v. on cellulose acetate strips is reported. Experience in 166 determinations on 137 patients shows the method to be a simple, practical, and apparently sensitive one for the determination of FIGLU in the urine.Results of the application of the measurement of urinary FIGLU with histidine loading as a test for folic acid deficiency are also reported.

Sixty-four tree nut samples (almonds, pecans, pine nuts, and walnuts) and 50 dried fruit samples (apricots, cranberries, papaya, pineapple, and raisins) were purchased from local supermarkets and analyzed for fungal contamination using conventional culture as well as molecular methods. The results of our study showed that the highest yeast and mold (YM) counts (5.34 log10 CFU g−1) were found in walnuts and the lowest in pecans. The most common mold in nuts was Aspergillus niger, relatively low numbers of A. flavus were found across the board, while Penicillium spp. were very common in pine nuts and walnuts. Low levels (2.00–2.84 log10 CFU g−1) of yeasts were recovered from only two pine nut samples. Fungal contamination in dried fruits was minimal (ranging from <2.00 to 3.86 log10 CFU g−1). The highest fungal levels were present in raisins. All papaya samples and the majority of cranberry, pineapple, and apricot samples were free of live fungi. The most common mold in dried fruits was A. niger followed by Penicillium spp. One apricot sample also contained low levels (2.00 log10 CFU g−1) of yeasts.

SUMMARY Serial measurements of 11 serum proteins have been made throughout 39 admissions of 36 patients to hospital for the treatment of acute attacks of ulcerative colitis. There was a striking correlation between rapid changes in C-reactive protein and pre-albumin concentrations and the clinical response to medical treatment. Measurements of the a,-acid glycoprotein, albumin, and total serum protein concentrations at the time of admission were found to correlate with the outcome of the attack. Measurement of these proteins provides a useful guide to the management of patients with attacks of ulcerative colitis.
