ABSTRACT
The efficacy of UV treatment to control bacterial adhesion onto hard surfaces was investigated in laboratory conditions. The major characteristics necessary for biofilm formation like extracellular polymeric substance (EPS) production, carbohydrate and protein concentration in EPS, and adhesion ability onto hard surface were studied using two bacterial strains isolated from marine biofilms. The results showed that there was a considerable difference between the control and UV treated bacterial cultures in their viability, production of EPS, and adhesion ability. The protein and carbohydrate concentration of the EPS and the adhesion of bacterial cells to surface were also considerably reduced due to UV treatment. This study indicates that treatment of water with UV light may be used to control biofilm development on hard surfaces.

Hemangioma is a common soft tissue lesion in the head and neck region. Hemangioma in the context of minor salivary glands is rarely encountered in surgical pathology practice, and for this reason most pathologist are often unfamiliar with its histomorphological features. We report a rare histological finding of salivary gland structures within a cavernous hemangioma, which may or may not have originated in the minor salivary gland.
