Abstract
OBJECTIVES To investigate the effects of anti-obesity drug sibutramine hydrochloride (SB) on redox state and biochemical parameters in the salivary glands. MATERIALS AND METHODS Adult male Wistar rats were randomly divided into the following groups (n = 8 per group): control rats treated with vehicle (C) and rats treated with SB (10 mg/kg/day) by intragastric gavage for 28 days. The parotid (PG) and submandibular (SMG) glands were processed using histomorphometric analysis, and total protein, amylase, mucin, and oxidative damage to lipids were determined by measuring the formation of thiobarbituric acid reactive substances (TBARS), total antioxidant capacity (TAC), uric acid (UA), total glutathione (tGSH), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), and AKT phosphorylation. RESULTS SB decreased the acinar area, and increased the stromal area in PG, while no effect on the morphometric parameters was observed in SMG. SB also increased oxidative damage to lipids (TBARs). The SB group showed lower total protein, amylase, TAC, UA, tGSH, SOD, CAT, and GPx than the C group in PG, while in SMG, SB decreased total protein, mucin, tGSH, SOD, CAT, and GPx. However, increased AKT phosphorylation observed in both salivary glands suggests that SB exerts low-intensity oxidative stress. CONCLUSIONS SB impaired enzymatic and non-enzymatic antioxidant defenses in the salivary glands of rats. CLINICAL RELEVANCE Chronic treatment with SB could mitigate salivary gland dysfunction due to disturbance of redox state.

Abstract
Cyclic antidepressants are still a dominating group of psychotherapeutic drugs used in the treatment of depression. Dry mouth is one of their major side effects. In this study we analyzed the effects of the long-term administration of the tricyclic antidepressant desipramine and the reversibility of this treatment following a 15-day washout period on different parameters in parotid gland function in aging rats. We hypothesized that glandular function would be decreased, and recovery delayed with age. Drug treatment affected body weight, glandular weight, DNA synthesis, and the concentration of soluble and structural membrane proteins. Surprisingly, parotid flow rate was increased with desipramine in all ages. While the concentration of secreted proteins was generally decreased with treatment, total proteins secreted were quite stable. SDS/PAGE analysis revealed prominent changes with desipramine. Amylase activity was depressed with treatment, but only low residual cellular enzyme activity was detected in the glandular supernatant. Therefore, a secretory impairment with desipramine was excluded. The content of the antimicrobial proteins peroxidase and lysozyme was increased with desipramine in all age groups. Most parameters measured revealed delayed recovery with age. These data indicate that the tricyclic antidepressant desipramine has profound effects on parotid gland function, accented with age.
