Main Component

Although titanium dioxide (TiO2) is an implantable biomaterial with its antibacterial activity, infection on TiO2 surfaces remains a problem for medical settings. According to our previous studies, curcumin, the main component of turmeric (Curcuma longa), partially hindered the attachment of Streptococcus mutans to human tooth surfaces. Therefore, it was examined whether several implant device-associated bacteria were able to adhere to nanosized TiO2 surfaces. In addition, the effect of curcumin on the bacterial adhesion was investigated. Bacterial strains were cultured on pure Ti and TiO2 surfaces with various nanotube sizes in the absence or presence of curcumin and observed by scanning electron microscopy. Consequently, most bacteria adhered to Ti and TiO2 surfaces. However, curcumin increased the adhesion of bacteria including S. mutans. The results suggest that bacterial adhesion to implant titanium surfaces can be augmented via curcumin ingestion.

The evaluation of the degree of bacteriaE. coliadhesion to modified surfaces of the chosen prosthodontic alloys was presented. The study was carried out on Co-Cr (Wironit), Ni-Cr (Fantocer), and Fe-Cr-Ni (Magnum AN) alloys. Bare substrate as a control and titanium dioxide coated samples were used. The samples were placed for 24 hours in bacterial culture medium. After incubation period, a number of bacterial cells were evaluated by scanning electron microscope. The study revealed that modification of the alloy surfaces by titanium dioxide coating significantly decreases the amount of bacteria adhering to the surfaces and that additionally bare metal alloy substrates have a different degree of susceptibility to bacterial adhesion.

Leukocyte Imaging

A prospective study was initiated to compare the clinically proven results concerning localization/extent and activity of inflammatory bowel diseases with those of 111ln-oxine leukocyte imaging. All patients studied were completely examined with barium enema x-ray, clinical and laboratory investigations, and endoscopy with histopathology. A total of 31 leukocyte scans were performed in 15 patients (12 with Crohn’s disease, 3 with ulcerative colitis). The scans were graded by comparing the cell uptake of a lesion (when present) and a bone marrow area providing a count ratio (CR). The inflammatory lesions were correctly localized on 26 leukocyte scans, and in 21 scans the scintigraphically estimated extent of disease was identical to endoscopy. In 5 cases the disease extent was underestimated, 4 scans in patients with relapse of Crohn’s disease were falsely negative, and in one patient with remission truly negative. The scintigraphically assessed disease activity was also in a good agreement with clinical disease activity based on histopathology in all cases. We conclude that leukocyte imaging provides valuable information about localization and activity of inflammatory bowel disease.
