Cancer is a disease in which a group of abnormal cells grow uncontrollably by disregarding the normal rules of cell division. Across several cancers, Hepatocellular carcinoma (HCC) is one of the most aggressive cancers in worldwide. It is held responsible for up to 1 million deaths globally per annum. HCC is an inflammation-related cancer, as a chronic inflammatory state is necessary for cancer appearance. In this study, the drug astaxanthin and encapsulated astaxanthin was tested against HCC. Mice were divided into 7 groups; Group I: control, Group II: DEN induced, Group III: DEN + 50 mg/kg astaxanthin, Group IV: DEN + 100 mg/kg astaxanthin, Group V: DEN + 50 mg/kg encapsulated astaxanthin, Group VI: DEN + 100 mg/kg encapsulated astaxanthin, Group VII: DEN + 10 mg/kg sorafenib. Regular diet was given. Body weight, Food intake, water intake was noted. Other biochemical parameters such as ALP, AST, Albumin, proteins and TNF-α was determined. Finally, the liver was removed from each mice of different group by sacrificing them and histopathology was done. In vivo evaluation in mice models showed significant antitumor activities by both encapsulated and non-encapsulated astaxanthin at 100 mg/kg as compared with the control, DEN induced group and positive drug sorafenib. This research suggested that encapsulated astaxanthin can also be used as chemotherapeutic agent for the treatment of Hepatocellular carcinoma (HCC).

Abstract Introduction The aim of obturation in the root canal is to completely seal the canal space to eliminate all the portals of entry and exit between root canal and periodontal space. Various techniques have been developed to achieve a hermetic seal. Materials and Methods As many as 150 extracted human maxillary central incisors were taken for the study. Biomechanical preparation was done up to F5 protaper file. According to different obturation techniques, samples were divided into six groups, keeping 30 samples in experimental and 15 samples in control groups. Group I–Lateral Condensation, Group II–Thermafil, Group III–Beefill, Group IV–GuttaFlow, Group V–Positive Control group, Group VI–Negative Control group. After obturation, the samples were immersed in 2% Rhodamine-B dye for 24 hours. Each sample was longitudinally sectioned to examine under confocal laser scanning microscope. Statistical Analysis The results were evaluated with ANOVA and posthoc Tukey honest significant difference (HSD) comparison test. Results The mean values of dye penetration of different groups were Group I (Lateral Condensation) 1.51 ± 0.451, Group II (Thermafil) 0.918 ± 0.399, Group III (Beefill) 1.30 ± 0.559. Group IV (GuttaFlow) 0.655 ± 0.396, Group V (Positive Control group) 1.96 ±0.046, Group VI (Negative Control group) 0 ± 0. The lowest mean value of apical microleakage was found in GuttaFlow amongst all experimental groups. Conclusion It can be concluded that the GuttaFlow obturating material exhibited better apical sealing ability with canal walls.

Exposure to relative chemicals has been shown to induce a genotoxic effect that can be observed through formation of micronucleus (MN) in polychromatic erythrocythes (PCE). Rumput Mutiara or Hedyotis corymbosa L. ethanolic extract (HcEE) is known to contain ursolic acid as major compound that possesses antigenotoxic activity on HepG2 cells. This study exerts in vivo approach aiming to evaluate the antigenotoxic effects of HcEE on cyclophosphamide (CP)-induced male Swiss mice. The ursolic acid on HcEE was determined by using thin layer chromatography with silica gel as stationary phase and chloroform-aceton (9:1) as mobile phase. The antigenotoxic activity was carried out by in vivo micronucleus test. Twenty four adult mice were equally divided into seven groups. Group I: control (untreated); group II: Na-CMC 0.5%; group III: CP 50 mg/kg BW; group IV: CP+HcEE 250 mg/kg BW; group V: CP+HcEE 500 mg/kg BW; group VI: CP+HcEE 1000 mg/kg BW; group VII: HcEE 1000 mg/kg BW. HcEE were given for seven days, while CP was administered on the last two days. On the seventh day, the peripheral blood from all mice were collected, smeared, and then stained with Giemsa. The frequencies of MNPCEs and %PCEs were evaluated. Molecular docking was performed to know the interaction between ursolic acid and CYP3A4 by using PLANTS software. There was similar hRF spot between HcEE with ursolic acid standard reference indicated that the extract almost positively contain ursolic acid. HcEE reduced MNPCEs significantly compared to CP group (p<0.05) and combination of CP with HcEE showed reduction of %PCEs (p<0.05). Based on molecular docking analysis, ursolic acid gave lower docking score than CP against CYP3A4 (PDB ID: 2V0M) and similar binding site on amino acid residues Ala 448, Ile 369, Thr 309, and Val 313. All of these data suggest that HcEE perform protective effect against CP-induced genotoxicity.Keywords: Antigenotoxic, Hedyotis corymbosa L., cyclophosphamide, micronucleus, molecular docking

Cyclophosphamide is chemotherapeutic agent that utilized for the treatment of different malignancies; however its’ used associated with numerous adverse effects. Vitamin B2 and vitamin B12 suggested having myeloprotective effect. This work is designed to investigate the myeloprotective effect of both vitamins against cyclophosphamide induced myelosuppression. One hundred adult rats of both sexes were used in this study. The animals were randomly enrolled into ten groups of 10 rats each. Group I: Control group. Group II: Cyclophosphamide-treated. Group III and Group IV Orally-administered vitamin B2 (10, and 40 mg/kg/day), respectively alone for 7 days. Group V: Orally-administered vitamin B12 (0.1 mg/kg/day) alone for 7 days. Group VI and Group VII: Orally-administered vitamin B2 (10, and 40 mg/kg/day), respectively for 7 days and a single IP injection of cyclophosphamide (150 mg/kg) at day 7.Group VIII: Orally-administered vitamin B12 (0.1 mg/kg/day) for 7 days and a single IP injection of cyclophosphamide (150 mg/kg) at day 7. Group IX: Orally-administered a combination of vitamin B2 (10 mg/kg/day) and vitamin B12 (0.1 mg/kg/day) for 7 days and a single IP injection of cyclophosphamide (150 mg/kg) at day 7. Group X: orally-administered a combination of vitamin B2 (40 mg/kg/day) and vitamin B12 (0.1 mg/kg/day) for 7 days and a single IP injection of cyclophosphamide (150 mg/kg) at day 7. On day eight, animals were sacrificed and blood collected for CBCs and femur bone were extracted for bone marrow histological examination. Vitamin B2 and vitamin B12 significantly (P<0.05) increase CBCs; and the combination of vitamins produce -a significant (P<0.05) increase in CBCs compared to corresponding counts in other Groups, and -improve histopathological changes compared to Group II rats. In conclusion both vitamins may have myeloprotective effects against cyclophosphamide-induced myelosuppression.

AbstractSprague-Dawley albino male rats (25) were divided into five groups consisting of five rats each. Polymer (polylactic acid) impregnated ALCAP capsules filled with 40 mg DFMO were implanted subcutaneously (SC) or intraperitoneally (IP) in Group I and II rats respectively. Rats in Group III were implanted with empty polymer impregnated ALCAP capsules (ALCAP control). Group IV rats were administered orally 3% DFMO in drinking water. Rats in Group V served as controls. Blood samples were collected every week for nine weeks via the tail artery. The concentration of DFNO in the plasma was determined. Data obtained showed that the levels of DFMO in the serum of rats in groups I, I, and IV were 64.71 ±4.08. 219.18 ± 14.48, 16.71 ± 5.21 ug ml−1, respectively at the end of nine weeks. Body weights of the controls and DFMO treated rats were not significantly different (p<0.05). The diarrhea often noted in rats treated orally with DFHO was not observed in rats implanted with ALCAP or ALCAP capsules filled with DFMO. The results of this study suggest that: (1) polymer impregnated ALCAP ceramic implants can be used to deliver DFMO in vivo in a sustained manner for long durations of time, and (2) a ceramic system can be designed to deliver DFNO and drugs such as DFMO in a sustained manner over long durations of time in humans.

The aim of this research was to determine the effect of taurine supplementation on the totalcount of leucocyte cells and erythrocyte cells of mice that have been induced to benzo (α)pyrene in vivo. The parameters of this experiment were the total count of leucocyte cells anderythrocyte cells of mice (Mus musculus L.). This experiment was conducted in a completerandomized design by using six treatments, each in five replications. The mice were dividedinto six groups. Group I used as control were not given any treatment. Group II were given0,2 mL of oleum olevarum (olive oil) orally to the end of the experiment. Group III wereinduced to benzo (α) pyrene without being given any taurine. Group IV were given 7,8mg/bw of taurine before being induced to benzo (α) pyrene. Group V were given 7,8 mg/bwof taurine after being induced to benzo (α) pyrene. Group VI were given 15,6 mg/bw oftaurine after being induced to benzo (α) pyrene. Mice of group III, V, and VI were injectedwith 0,5 mL of benzo (α) pyrene solution every day for 10 days on their subcutant tissue forthe purpose of a nodule being formed in this area. It was then continued by giving taurineorally for 15 days. In the final treatment, mice blood was taken to count the leucocyte cellsand erythrocyte cells. The data were analyzed using ANOVA (Analysis of Variance) thencontinued by calculating least significant difference at 5 per cent level of significance. Theresults indicated that taurine had the ability to reduce leucocyte cells into its normalquantity, and was able to increase the number of erythrocyte cells of mice suffered fromleukaemia back to normal.Key words: benzo (α) pyrene, leukaemia, leucocyte, mice , taurine

Background: Gamma irradiation has been recognized as a reliable and safe method for improving the bio-components of plants. Objectives: This study aimed to evaluate the effect of irradiated chicory root extract on liver necrosis. Methods: Twenty-four adult male Wistar rats were divided equally into six treatment groups: Group I) Control, Group II) CCl4, Group III) CCl4 + irradiated chicory root extract, Group IV) CCl4 + chicory root extract, Group V) irradiated chicory root extract, and Group VI) chicory root extract. Animals were treated for four weeks. At the end of the study, catalase, SOD, lipid peroxidation, ALT, AST, histopathology, and Fourier Transform Infrared Spectroscopy (FTIR) were evaluated. Results: The results showed that the elevated levels of LPO, ALT, and AST in the CCl4 group decreased due to irradiated chicory and chicory root extract. Also, molecular changes and abnormalities in liver tissue improved due to irradiated chicory and chicory root extract. Moreover, the results showed that irradiated chicory roots were more effective than non-irradiated chicory. Conclusions: In conclusion, gamma-ray can increase the bioactive components of chicory root and is more effective in the scavenging of free radicals that cause liver necrosis in CCl4-treated rats.

Pyrethroid cyhalothrin (PC) is an insecticide that is used worldwide for pest control in agriculture and household use. Samoa extract (SE) is a potent antioxidant protecting cells from oxidative stress. The present study investigates the protective and therapeutic effect of SE on PC-induced changes in sperm quality in male rats. Fifty adult male albino rats were divided into five groups: group I: served as control; group II: received PC i.p. only (6.2 mg/kg b.wt.); group III: received SE only (100 mg/kg b.wt., p.o.) for eight weeks; group IV: received SE as a protective agent daily for eight weeks, then followed by the administration of PC (i.p.) three times a week for two weeks; group V: exposed to PC (i.p.) three times a week for two weeks, then treated with the SE daily for 8 weeks. Results showed that PC caused markedly impaired sperm quality (a count, viability, motility, and abnormality). Compared to PC-treated animals, SE in the protective group markedly restored the alteration of sperm indices. However, SE in the curative group was found to be less effective in restoring PC-induced alterations. In conclusion, the data of this study revealed that the SE as a protective agent is more effective than as a therapeutic agent. Keywords: Samoa; Pyrethroid; Sperm quality; Rat

Abstract The aim of the study was to evaluate the immune effects of genetically modified (GM), insect resistant corn (MON810) expressing toxin protein of Bacillus thuringiensis, and glyphosate-tolerant soybean meal (Roundup Ready MON-40-30-2), which are used as the feed mixture components in domestic animals. The study was conducted on 60 pigs (36 fatteners and 24 sows), 20 calves, 40 broilers, and 40 laying hens. Each species was divided into four basic nutritional groups: group I (control) - conventional feed, group II - feed consisted of GM soybean meal and non-modified corn, group III - non-modified soybean meal and GM corn, group IV - GM soybean meal and GM corn. Moreover, in the experiment on fatteners two additional groups were formed: group V - animals fed both conventional soybean meal and bruised grain, and group VI - GM soybean meal and conventional bruised grain. The results of study did not reveal any significant effect of feed mixtures containing GM components on the immune response in all animals regardless of their species and technological producing groups.
