Changes in rat parotid salivary gland weight and functional parameters were evaluated at 8 to 10 days post irradiation in WR-2721 protected and non-protected animals following exposure to a single 15.3 Gy dose of Cs-137 radiation to the head. Glandular fluid secretory capacity was assessed by maximum flow rate, total volume of saliva and duration of secretion following pilocarpine stimulation. Protection against radiomucositis was also evaluated indirectly by daily monitoring of food and water intake, body weight and paraoral symptomatology. WR-2721 provided a significant degree of protection for all glandular functional parameters as well as gland weight. Relative protective factors (RPF) were computed for irradiated protected and non-protected animals compared to their sham-irradiated, pair-fed controls. The calculated RPFs were: Gland weight 1.9, maximum flow rate 2.9, volume of saliva 2.1 and duration of secretion 2.1 for a mean "relative protection" of 2.25. Substantial protection against radiomucositis in protected animals was evident by a progressive gain in body weight and lack of oral signs and symptoms as compared to non-protected animals. Protection against radiomucositis and preservation of residual parotid gland secretory capacity as determined by functional parameters suggests that WR-2721 may be of significant benefit in alleviating oral symptoms and maintaining salivary gland function for patients receiving radiotherapy for head and neck tumors.
