The effect of sucrose (60 per cent w/w) and 1 M glycine as thermal stabilizers for fibrinogen in cryoprecipitate was studied. Sucrose (9.2 g) and glycine (0.9 g) were dissolved in 6 g of cryoprecipitate and the solution was pasteurized at 60 degrees C for 10 h. The preparation was then dialyzed for 20 h in phosphate buffered saline (PBS), lyophilized, stored for one week at -40 degrees C and resuspended in distilled water. The recovery of total proteins and fibrinogen in the final product averaged 66.4 +/- 4.1 per cent and 43.8 +/- 6.4 per cent of the initial contents, respectively (mean +/- SEM, N = 9). The pasteurization of cryoprecipitate in the presence of PBS (control experiments) produced extensive precipitation, which is characteristic of protein denaturation. Thus, this method partially protected fibrinogen and other proteins in cryoprecipitate from inactivation by prolonged exposure to heat during pasteurization

Twenty one surgically documented cases of Meckel's diverticulum in children treated at Kasturba Hospital, Manipal since 1981 are reviewed. Of them, 14 presented with intestinal obstruction, 2 with pain abdomen, 2 with Littre's hernia and 2 were found incidentally. Only one patient presented with gastrointestinal bleeding. The clinical profile of these patients is analyzed.
