In recent years, more head and neck cancer patients have been treated with radiotherapy. Radiation-induced mucositis is a common and dose limiting toxicity of radiotherapy among patients with head and neck cancers. Patients undergoing radiation therapy for head and neck cancer are also at increased risk of developing oral candidiasis. A number of new agents applied locally or systemically to prevent or treat radiation-induced mucositis have been investigated, but there is no widely accepted prophylactic or effective treatment for mucositis. Topical Aloe vera is widely used for mild sunburn, frostbites, and scalding burns. Studies have reported the beneficial effects of Aloe gel for wound healing, mucous membrane protection, and treatment of oral ulcers, in addition to antiinflammatory, immunomudulation, antifungal, scavenging free radicals, increasing collagen formation and inhibiting collagenase. Herein the author postulates that oral Aloe vera mouthwash may not only prevent radiation-induced mucositis by its wound healing and antiinflammatory mechanism, but also may reduce oral candidiasis of patients undergoing head and neck radiotherapy due to its antifungal and immunomodulatory properties. Hence, Aloe vera mouthwash may provide an alternative agent for treating radiation-induced oral mucositis and candidiasis in patients with head and neck cancers.

Flaxseed is one of the rich sources of α-linolenic acid and lignan. Flaxseed and its components have antioxidant, hypolipidemic and hypoglycemic effects. The study aimed to investigate the effect of flaxseed enriched yogurt on glycemic control, lipid profiles and blood pressure in patients with type 2 diabetes. A randomized, open-labeled, controlled clinical trial was conducted on 57 patients with type 2 diabetes. Participants were assigned to receive 200 g 2.5% fat yogurt containing 30-g flaxseed or plain yogurt daily for 8 weeks. Anthropometrics and biochemical parameters were evaluated at the beginning and end of the study. After 8 weeks of supplementation, Hemoglobin A1c was significantly decreased in the intervention group compared to control (p = 0.007). Also, at the end of the study, significant differences were seen between the flaxseed enriched yogurt and control groups in triglycerides and total cholesterol concentrations (p = 0.04 and p = 0.01), systolic blood pressure and diastolic blood pressure (p = 0.02 and p = 0.002, respectively). However, we did not find any difference between 2 groups in low-density lipoprotein, high-density lipoprotein, body weight and waist circumference (p > 0.05). Our results showed that the addition of flaxseed to yogurt can be effective in the management of type 2 diabetes. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02436369

OBJECTIVE: To evaluate the protective effect of Zataria multiflora extract, an antioxidative medicinal plant, against cyclophosphamide (CP)-induced oxidative lung damage in mice. METHODS: Mice were intraperitoneally pre-treated with various doses of Zataria multiflora extract (50, 100, 200, and 400 mg/kg) once daily for 7 consecutive days. Animals were then injected with a single 200 mg/kg intraperitoneal dose of CP 1 h after the last administration of O. vulgare. Twenty-four hours later, mice were euthanized, the lungs were immediately removed, and biochemical and histological studies were conducted. RESULTS: A single dose of CP markedly altered the levels of several biomarkers associated with oxidative stress in lung homogenates. Pretreatment with Zataria multiflora significantly inhibited the elevation of lipid peroxidation level and the depletion in glutathione content, and superoxide dismutase and catalase activities induced by CP in lung. In addition, Zataria multiflora effectively alleviated CP-induced histopathological abnormality and pulmonary damages in mice lung tissues. CONCLUSIONS The results reveal that Zataria multiflora protects lung tissues from CP-induced toxicity and suggest a role for oxidative stress in the pathogenesis of lung toxicity produced by CP in mice. Because Zataria multiflora has been extensively used as an additive agent and is regarded as safe, it may be used concomitantly as a good supplement for reducing organ toxicity in patients undergoing chemotherapy, besides their consolidated ethnopharmacological uses.
