This paper presents some of the oral aspects encountered in bone marrow transplant (BMT) patients, as reflected in recent research conducted in the Department of Oral Medicine. Oral infections caused by Enterobacteriaceae were found to be responsible for a large proportion of positive cultures, during different stages of the transplantation process. Mucositis was constantly detected concomitant with the infections. It correlated with granulocytopenia and fever. The mucositis improved together with the immune system reconstitution. Immunoglobulins in saliva of BMT patients showed a drastic reduction following the patients' conditioning protocol and a return to normal levels soon after the transplantation. IgA, IgM and IgG were studied. Saliva was also shown to play an important role in the fibrinolytic system, through its plasminogen activator inhibitory contents. It seems that the active molecules are contained in the oral epithelial cells.

Inverse gas chromatography (IGC) has been used to characterise the surface properties of polycaprolactone (PCL) and poly(lactic acid) (PLA). The dispersive component of the surface free energy (gamma(S)(D)) was found to be very small for both of them--values close to 30 mJ/m(2) in the case of the PLA and ca. 40 mJ/m(2) for the PCL. The retention times of the n-alkanes, necessary to calculate the dispersive component of the surface energy, were obtained from the maximum, the centre at half height and the centre of mass of the chromatographic peak. While the values obtained using the first two parameters appear not to be affected by the peak asymmetry, in spite of having been obtained above the glass transition temperature of the polymer, the values obtained using the latter have been found to be not reliable. The drawbacks of using n-alkanes with a very small retention time have also been discussed, estimating the error it can introduce in the final results. Finally, the acid-base properties of the two biopolymers were determined using the approaches suggested by Schultz et al. and by St. Flour and Papirer. Although both methods describe the surfaces of PLA and PCL as neutral ones, differences between the values of the parameters K(A), K(D) and S(C) were obtained.
