The aim of the study is to evaluate the acute biochemical and histological changes in rat kidneys after treatment with grayanotoxin (GTX) of rhododendron honey (RH). A total of 60 Sprague-Dawley female rats were divided into five groups of 12 rats each, one being a control group (group 1) and group 2 was treated with 0.015 mg/kg/bw of GTX standard preparation via intraperitoneal injection. Groups 3, 4, and 5 were given RH at doses of 0.1, 0.5, and 2.5 g/kg/bw, respectively, via oral gavage. Compared to the control group, significant increases were observed in glucose, blood urea nitrogen (BUN), and creatinine levels of the GTX-injected groups after 1 h. However, in low dose RH group, such an increase was not observed and had a normal appearance histologically. Therefore, low dose (1 g/kg/bw) of RH produces no acute adverse effects on renal functions of rats.
Citrus and thyme honeys were determined to have low GI, while serum insulin levels were significantly lower after the consumption of chestnut honey. Long-term research is needed to compare the effects of honey consumption on healthy and diabetic individuals.
Adenoid cystic carcinoma (ACC) is an aggressive malignant neoplasm of the secretory glands. Conventional chemotherapy has poor effectiveness against metastatic ACC. Thus, a novel effective therapy is needed against metastatic ACC. A majority of ACCs (up to 94%) express c-kit. Imatinib is monoclonal antibody with specific activity against c-kit but has not been found to be effective in treating patients with ACC in which c-kit is overexpressed and activated. The NF-κB and mTOR pathways have been shown that ubiquitously and concurrently activated, indicating that the inhibition of these pathways may represent a novel treatment approach for patients with ACC. Curcumin has been shown to inhibit NF-κB and NF-κB-related pathways. 43-year-old patient was diagnosed ACC from submandibular salivary gland. After complete resection of tumor adjuvant radiotherapy was initiated. Seven years later multiple lung metastases were detected and ACC was confirmed by re-biopsy. First-line chemotherapy failed. NF-κB and c-kit were overexpressed in the metastatic specimens. Therefore, we treated the patient with metastatic chemoresistant ACC with imatinib 400mg/day and intravenous curcumin 225mg/m(2) twice a week plus oral bioavailable curcumin Arantal(®) 2×84mg/day. At 24 months, we observed near complete anatomic and complete metabolic response. To our knowledge, this is the first report of a patient with a c-kit-positive ACC that is successfully treated with the combination of imatinib and curcumin in an integrative approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
