Trehalose has several novel anti-inflammatory and cell-protective functions. We hypothesized that lyophilized aspirin/trehalose could decrease the severity of aspirin-induced gastropathy. Thirteen dogs were assigned into aspirin, lyophilized aspirin/trehalose, and control groups, and the gastric lesions were assessed on gastroscopy with the modified Lanza scale. Another 6 dogs were used to measure the plasma aspirin concentration by high-performance liquid chromatography after aspirin or lyophilized aspirin/trehalose administration. The results indicated that lyophilized aspirin/trehalose induced less gastric ulceration than aspirin despite maintaining therapeutic concentrations of plasma aspirin in both the groups. Lyophilized aspirin/trehalose might be a solution to decrease aspirin-induced gastropathy.

The effect of tetrapod-shaped alpha tricalcium phosphate granules (Tetrabones® [TB]) in combination with basic fibroblast growth factor (bFGF)-binding ion complex gel (f-IC gel) on bone defect repair was examined. Bilateral segmental defects 20-mm long were created in the radius of 5 dogs, stabilized with a plate and screws, and implanted with 1 of the following: TB (TB group), TB and bFGF solution (TB/f group), and TB and f-IC gel (TB/f-IC group). Dogs were euthanized 4 weeks after surgery. Radiographs showed well-placed TB granules in the defects and equal osseous callus formation in all the groups. Histomorphometry revealed that the number of vessels and volume of new bone in the TB/f-IC group were significantly higher than those in the other groups. However, no significant differences in neovascularization and new bone formation were observed between the TB/f and TB groups. Furthermore, no significant difference in the lamellar bone volume or rate of mineral apposition was observed among groups. These results suggest that increased bone formation might have been because of the promotion of neovascularization by the f-IC gel. Therefore, the combinatorial method may provide a suitable scaffold for bone regeneration in large segmental long bone defects.
