R, it showed antimutagenic activity [Table 2]. These information recommend that this essential oil may be utilized as a chemopreventive agent for cancer.[31]Antimutagenic assayThe micronucleus assay was carried out in male and female Swiss mice 3 months of age weighing in between 20 and 40 g. The animals were conditioned in cages with controlled temperature and humidity, a 12 h light ark cycle, and ad libitum access to water and food. The mice have been offered by the Vivarium of Complexo Biopr icas of University Vila Velha. The animals were divided into five groups, with equal numbers of males and females in every group. The adverse handle group (CN, n = 6) received the vehicle (peanut oil) orally plus the positive manage group (CP, n = six) received cyclophosphamide (45 mg/kg) intraperitoneally 24 h prior to euthanasia. The groups treated together with the P. heptaphyllum critical oil have been Protium 25 (PROT25, n = six), Protium 50 (PROT50, n = six), and Protium one hundred (PROT100, n = six). These groups orally received the P. heptaphyllum critical oil diluted in a automobile at doses of 25, 50, and one hundred mg/kg, respectively, twice daily for three days. The penultimate dose was applied simultaneously with cyclophosphamide 24 h ahead of euthanasia. The micronucleus test created initially by Schmid,[28] and all assays, such as collection with the bone marrow specimens to preparing the slides, had been run as described by Ribeiro et al.,[29] following the recommendations recommended by the Guideline for the Testing of Chemical compounds (OECD).[30] Also, this evaluation was performed by a biologist blind to the experimental groups. The results have been presented as the frequency of polychromatic erythrocytesmicro nucleated (PCEMN) and cytotoxicity index PCE/normochromatic erythrocytes (NCE) ratio. The protocol was approved by the Ethics Committee and Bioethics and Animal Welfare UVV (Protocol No. 116/2010).DISCUSSIONThe phytochemical evaluation benefits agree with other research which have evaluated the chemical HSP70/HSPA1A, Human (HEK293, His) composition from the crucial oil in the resin of P. heptaphyllum in various localities, for example Manaus, Maranh , and Acre; the prevalence of PD-L1 Protein Accession monoterpenes was also observed in these studies.[6,7,32]Table 1: Chemical composition on the oil of Protium heptaphyllum obtained inside the years 2009, 2011, and 2013 analyzed by GC S Substance IK 2009 ( ) 2011 ( ) 2013 ( ) Terpinene 1018 3.ten two.29 three.14 pCymen8ol 1206 2.50 10.12 six.6 Terpinolene 1088 32.70 35.81 37.78 Tujeno 931 0.40 11.05 yTerpinene 1062 2.40 Felandrene 1005 three.97 Pinene 939 4.20 four.35 pCymene 1026 7.90 26.66 38.08 1.76 Mirtenal 1027 Camphor 1143 1.27 transCarveol 1217 1.13 cisLimonene oxide 1134 1.08 3Dcarene 1011 1.09 3Carene NI 15.00 Myrcene NI 0.40 Bourbonene 1384 1.25 Limonene NI 22.00 Gangrene D NI 0.40 cisPinocarveol 1183 0.54 4.04 Sabinene 976 Dcadinene 1524 0.38 1520 0.09 gCadinene Total identifi d 91.00 96.61 95.87 IK: Reported Kovats index[23]; ( ): Relative percentage of the substances; NI: Not identifi d; GCMS: Gas chromatographymass spectrometry Table 2: Numbers of PCE and NCE in 200 cells and MN-PCE in 2000 PCEs as well as the cytotoxicity index (PCE/NCE) ratio in the bone marrow of mice Groups PCE NCE MN-PCE PCE/NCE NC 125sirtuininhibitor3 93sirtuininhibitor0 2.0sirtuininhibitor.1 1.31sirtuininhibitor.26 CP45 73sirtuininhibitor5 114sirtuininhibitor5 12.2sirtuininhibitor.eight 0.61sirtuininhibitor.12 PROT25 116sirtuininhibitor8�� 91sirtuininhibitor5�� 2.5sirtuininhibitor.4�� 1.34sirtuininhibito.
