PURPOSE Reactive oxygen species play a role in a number of degenerative conditions including osteoporosis. Flavonoids as phyto-oestrogens exert physiological effects against oxidative stress diseases. We developed a retinoic acid-induced bone loss model of rats to assess whether flavonoids and alendronate as positive control have role against oxidative(More)
The radioprotective effects of ethanolic extract of propolis (EEP) and quercetin on the white blood cells of the whole-body irradiated CBA mice were investigated. Irradiation was performed using a gamma-ray source ((60)Co), and absorbed dose was 9 Gy. The efficiency of test components was evaluated when given intraperitoneally (ip) at a dose of 100 mg(More)
Body size has a pervasive effect on animal functioning and life history with size dependent changes in performance and physiology throughout ontogeny being common in many ectothermic vertebrates. However, as selection on juvenile life history stages is strong, juveniles often offset the disadvantages of small body size by disproportionate levels of(More)
Despite the excellent chemotherapeutic effect of irinotecan, its cytotoxicity and genotoxicity in normal cells remains a major problem in chemotherapy. This study was carried out to find whether propolis preparations and related flavonoids (quercetin, naringin) might enhance irinotecan-induced cytotoxicity to tumor cells in mice bearing Ehrlich ascites(More)
PURPOSE The purpose of this study was to investigate the effect of local chemoimmunotherapy and hyperthermal intraperitoneal chemotherapy (HIPEC) in a mouse model of induced peritoneal carcinomatosis. MATERIAL AND METHODS Peritoneal carcinomatosis in mice was produced by intraperitoneal implantation of MCa cells (5 x 10(3)). Interleukin-2 (4.1 x 10(4)(More)
Traces of pesticides imazalil, cypermethrin and carbendazim are detected in plants used for human consumption. To explore whether their application in oral combinations will induce DNA breaks in hepatocytes, a subchronic in vivo experiment was performed in Swiss mice. Doses of 10 mg kg(-1) of imazalil (im) and cypermethrin (cy), and 20 mg kg(-1) of(More)
The aim of this study was to assess radioprotective effects of quercetin and the ethanolic extract of propolis (EEP) in CBA mice exposed to a single radiation dose 4 Gy (60Co). The mice were treated with 100 mg kg(-1) quercetin or EEP a day for three consecutive days either before (pre-treatment) or after gamma-irradiation (therapy). Leukocyte count was(More)
We investigated possible synergistic action of anticancer drug Irinotecan (IRI) combined with ethanolic (EEP) and water-soluble (WSDP) derivate of propolis on Swiss albino mice injected with Ehrlich ascites tumor (EAT). For survival analysis mice were administered WSDP and EEP (100 mg/kg) daily for 3 consecutive days, beginning on 3rd day after EAT cell(More)
The relationship between DNA damage and repair of peripheral blood leukocytes, liver, kidney and brain cells was investigated in Swiss albino mice (Mus musculus L.) after exposure to sevoflurane (2.4 vol% for 2 h daily, for 3 days). Genetic damage of mouse cells was investigated by the comet assay and micronucleus test. To perform the comet assay, mice were(More)
We investigated antitumor, genotoxic, chemopreventive, and immunostimulative effects of local chemoimmunotherapy and hyperthermal intraperitoneal chemotherapy (HIPEC) in a mouse-bearing Ehrlich ascites tumor (EAT). Mice were treated with water-soluble derivative of propolis (WSDP) at a dose of 50 mg kg(-1) , 7 and 3 days before implantation of EAT cells,(More)
