| Abstract The aim of this study was to investigate in vitro antioxidant properties and in vivo protective effects of the methanol extract of the Hypericum triquetrifolium Turra (HT) seed against acute hepatotoxicity, myelotoxicity and hematotoxicity in rats induced by cyclophosphamide (CP). In order to investigate in vivo protective effects of the HT extract on rat tissues, the rats were divided into nine groups. The toxic effects of CP and the protective effects of HT extract on nucleated cells that are produced by bone marrow, serum alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and oxidative stress index (OSI) levels were investigated biochemically. Additionally, liver tissue samples were examined for... |

| ABSTRACT Aegle marmelos (L.) (Rutaceae) commonly known as bael is an important medicinal fruit tree. The present study focused on the effects of aqueous extract of Aegle marmelos (AEAM) on the testis and sperm characteristics induced by cyclophosphamide (CPA) in mice. Thirty six adult Parke’s strain mice were divided into six groups: group I given only distilled water (control); group II administered with AEAM alone once in a week for five weeks; group III administered with CPA (200 mg/kg b.w., intraperitoneally) once in a week for five weeks and group IV-VI CPA along with AEAM (400, 500 and 600 mg/kg b.w., orally). CPA was found to reduce gonadosomatic index (GSI), sperm counts, motility, viability, antioxidant activities and induced histopathological... |

| In the present study, the ability of Punica granatum ethanolic leaf extract (PGL) and Punica granatum ethanolic fruit extract (PGF) to induce mutagenicity or to modulate the genotoxic effects induced by the alkylating agent cyclophosphamide (CP) was evaluated. Swiss male mice were treated by gavage for 10 days with PGL or PGF (12.5, 25, 50, and 75 mg/kg/day) prior to exposure to CP (i.p. 200 mg/kg), 24 h after the end of the treatment. Initial observations revealed that normal mice treated with both extracts (12.5, 25, 50, and 75 mg/kg/day) showed a similar micronucleated polychromatic erythrocyte (MNPCE) frequency to that of the control group. Investigation of the protective effect of PGL and PGF based on data analysis revealed that, irrespective of dose... |

| ABSTRACT Metronomic chemotherapy consists of an anticancer modality treatment. It is applicable in patients at an advanced stage, with the objective of increasing overall survival. The aim of this study was to report an anal sac apocrine carcinoma case in a dog with lymph node metastasis treated with metronomic chemotherapy sequential to surgery and conventional chemotherapy using gemcitabine and carboplatin. Metronomic chemotherapy was associated with cyclooxygenase-2 (COX-2) inhibitors, due to strong tumor COX-2 immunohistochemistry expression. Metronomic chemotherapy was initiated with cyclophosphamide, but it was replaced by lomustine, also in metronomic dosage, due to adverse effects. Treatment showed effectiveness, since the patient's overall... |

| The antioxidant and free radical scavenger properties of melatonin have been well described in the literature. In this study, our objective was to determine the protective effect of the pineal gland hormone against the DNA damage induced by cyclophosphamide (CP), an anti-tumor agent that is widely applied in clinical practice. DNA damage was induced in rats by a single intraperitoneal injection of CP (20 or 50 mg/kg). Animals received melatonin during the dark period for 15 days (1 mg/kg in the drinking water). Rat bone marrow cells were used for the determination of chromosomal aberrations and of formamidopyrimidine DNA glycosylase enzyme (Fpg)-sensitive sites by the comet technique and ofXpf mRNA expression by qRT-PCR. The number (mean ± SE) of... |

| The present study assessed central nervous system (CNS) and immune system changes in murine fetuses after cyclophosphamide (CP) exposure during intrauterine life. A single CP dose of 0, 10, or 20mg/kg body weight was administered by intraperitoneal inj ection to pregnant mice (20/group) on day 11 of gestation (GD 11) and fetuses were evaluated on day 19 of gestation (GD 19). Fetuses were examined for external changes, and then the brains and thymuses were removed for further evaluations of histological changes, protein content, apoptotic cell count, DNA fragmentation, and in vitro cell proliferation using 1 fetus/litter for each assessment. Brains and thymuses from CP-exposed fetuses were smaller in size and distorted in overall shape compared to those... |

| ABSTRACT Capirona decorticans (Rubiaceae) is popularly used to treat warts, wounds, mycoses and scabies, and is also a component of the Ayahuasca tea. Despite its popular use, the phytochemical and pharmacological research on this species is limited. Therefore, this work quantified phenolic compounds in the ethanolic extract (EE) and hydromethanolic fraction (FM) (406, 293 mgEAG g-1, respectively) from leaves of C. decorticans. We identified flavonoids by LC-MS/MS-MMR-ESI (apigenin, rutin, luteolin, miricetin, quercetin, quercetin-3-β-D-glucoside, quercetrin), and evaluated oxidative stress and mutagenic/antimutagenic effect of EE and FM through an in vivo experiment using Swiss mice and cyclophosphamide (CP) as an inducer of DNA damage and oxidative... |

| Ample evidence suggests that cancer is triggered by mutagenic damage and diets or supplements capable of reducing such incidences can be related to the prevention of neoplasy development or to an improvement in life quality of patients who undergo chemotherapy. This research aimed to evaluate the antimutagenic and antigenotoxic activity of β-glucan. We set up 8 experimental groups: control (Group 1), cyclophosphamide (Group 2), Groups 3-5 to assess the effect of β-glucan administration, and Groups 6-8 to evaluate the association between cyclophosphamide and β-glucan. The intraperitonial concentrations of β-glucan used were 100, 150 and 200 mg/kg. Micronucleus and comet assays showed that within the first week of treatment β-glucan presented a damage... |

| The effects of mimosine (MI), which is an amino acid that is derived from Leucaena leucocephala, were evaluated on the growth of ascitic Ehrlich tumors, and the effects of the combination treatment of MI and cyclophosphamide (CY) on tumor growth were also assessed. Mice were divided into groups that received the following treatments over the course of 20 days: phosphate buffer solution (CO), MI, Ehrlich cells (E), E plus CY (EC), E plus MI (EM) and E plus MI and CY (EMC). No signs of toxicity were detected in the mice from the MI group. The mice from the EMC group showed reductions in body weights when compared with those from the E group. The animals from the EC, EM and EMC groups showed reductions in ascitic volume compared with those from the E group.... |

| Chemotherapy with oxazaphosphorines, such as cyclophosphamide (CYP), is often limited by unacceptable urotoxicity. Without uroprotection, hemorrhagic cystitis (HC) becomes dose-limiting. To compare the uroprotective efficacy of classical 2-mercaptoethanesulfonic acid (Mesna) treatment with dexamethasone in CYP-induced HC, male Wistar rats (150-200 g; N = 6 in each group) were treated with saline or Mesna (40 mg/kg, ip) immediately and 4 and 8 h after ip administration of CYP (200 mg/kg). One, 2 or 3 doses of Mesna were replaced with dexamethasone (1 mg/kg, ip). The animals were sacrificed 24 h later. Cystitis was evaluated by determining the changes in bladder wet weight (BWW) and by macroscopic and microscopic analysis. CYP treatment induced a marked... |

| Large numbers of cyclophosphamide- or carrageenan-pretreated immunosuppressed adult ddY mice died within 10 days after inoculation with several species of opportunistic bacteria, including P. aeruginosa, K. pneumoniae, E. coli, S. aureus and methicillin resistant S. aureus. When immunosuppressed mice were administered bacteria in combination with two 100 μg/mouse intramuscular doses of a newly synthesized peptide, Obiopeptide-1 (OP-1), survival rates increased significantly. At 24 and 48 hours after intraperitoneal inoculation with P. aeruginosa, counts of viable organisms from the livers, spleens, lungs, hearts, and kidneys of mice that were administered cyclophosphamide in combination with OP-1 were significantly lower than counts from mice that were... |
