Background: The incorporation of oils in the diet may have promoting or inhibitory effects on Colorectal Cancer (CRC). In this study, azoxymethane (AOM) was used to mimic CRC in rats and the effect of sunflower oil on cancer progression in the colon of the rats was tested. Objective: This study was conducted to investigate the effect of sunflower oil on preneoplastic cancer properties on the colonic mucosal surface for tumors and the aberrant crypt foci (ACF). Methods: Six weeks old Sprague-Dawley male rats were randomized into 4 groups of 6 rats each, namely naïve, positive control, negative control and sunflower oil-fed. CRC was induced by AOM by subcutaneous injection of 20 mg/kg. After CRC induction, the rats were given respective treatment of either basal diet (naïve group), 10 mg/kg indomethacin (positive control), 0.9% saline (negative control), and 7% sunflower oil (experimental group) daily by oral gavage for 42 days. Rats were sacrificed by cervical dislocation; colon samples were visually observed for any tumors on the colonic mucosal surface and evaluated for ACF; histopathological examinations were also performed. Results: The mean body weights of the rats were similar in all groups as per one-way ANOVA. A total of 3 ACF were found in the negative group while none were observed in others. The crypts appeared regular with circular luminal openings and were arranged closely packed together in the naïve group. Crypts in the positive and treated group had a similar appearance like naïve group. Conclusion: Sunflower oil inhibition of the preneoplastic cancer ACF properties were tested but were found to be insignificant when administered during CRC treatment or management. However long-term experiment with a greater number of days will yield better development of tumor and ACF development and will be useful identifying the molecular mechanism.

This study investigated the effects of Brazilian Red Propolis (BRP) extract on seven-day-old multispecies subgingival biofilms. Mixed biofilm cultures containing 31 species associated with periodontal health or disease were grown for six days on a Calgary device. Then, mature biofilms were treated for 24 h with BRP extract at different concentrations (200–1600 µg/mL), amoxicillin (AMOXI) at 54 µg/mL (positive control) or vehicle (negative control). Biofilm metabolic activity was determined by colorimetry, and bacterial counts/proportions were determined by DNA–DNA hybridization. Data were analyzed by Kruskal–Wallis and Dunn’s tests. Treatment with BRP at 1600, 800 and 400 μg/mL reduced biofilm metabolic activity by 56%, 56% and 57%, respectively, as compared to 65% reduction obtained with AMOXI. Mean total cell counts were significantly reduced in all test groups (~50–55%). Lower proportions of red, green and yellow complex species were observed upon treatment with BRP (400 µg/mL) and AMOXI, but only AMOXI reduced the proportions of Actinomyces species. In conclusion, BRP extract was as effective as AMOXI in killing seven-day-old multispecies biofilm pathogens and did not affect the levels of the host-compatible Actinomyces species. These data suggest that BRP may be an alternative to AMOXI as an adjunct in periodontal therapy. In vivo studies are needed to validate these results.

Chemoprevention has become an important area in cancer research due to low success rate of current therapeutic modalities. Diet plays a vital role in the etiology of cancer. This research was carried out to study the chemopreventive properties of germinated rough rice (GRR) crude extract in Sprague-Dawley rats induced with azoxymethane. Germination of rough rice causes significant changes in several chemical compositions of presently bioactive compounds. These compounds may prevent or postpone the inception of cancer. Fifty male Sprague-Dawley rats (6 weeks of age) were randomly divided into 5 groups which were (G1) induced with azoxymethane (AOM) and not given GRR (positive control), (G2) induced with AOM and given 2000 mg/kg GRR, (G3) induced with AOM and given 1000 mg/kg GRR, (G4) induced with AOM and given 500 mg/kg GRR, and (G5) not induced with AOM and not given GRR crude extract (negative control). To induce colon cancer, rats received two IP injections of AOM in saline (15 mg/kg) for two subsequent weeks. Organs were removed and weighed. Aberrant crypt foci (ACF) were evaluated histopathologically. β-Catenin expressions were determined by Western blot. Treatment with 2000 mg/kg GRR crude extract not only resulted in the greatest reduction in the size and number of ACF but also displayed the highest percentage of nondysplastic ACF. Treatment with 2000 mg/kg GRR also gave the lowest level of expression in β-catenin. Thus, GRR could be a promising dietary supplement for prevention of CRC.

Mucuna pruriens, Ashwagandha, and Tribulus terrestris are known as the enhancers for sexual health, functional activities, vitality, and longevity. These herbs had been widely used in the Ayurveda medicine as aphrodisiacs through the ages, and their efficacy was also verified separately in our previous publication. Therefore, the aim of this study was to determine the effects of Mucuna, Ashwagandha, and Tribulus complexes on sexual function in rats. Twenty-eight male rats allocated to four groups as follows: (i) negative control (C); (ii) positive control or sildenafil citrate treated group (5 mg/kg) (S); (iii) MAT1 (combination of 10 mg Mucuna (M) + 10 mg Ashwagandha (A) + 10 mg Tribulus (T)/kg BW); (iv) MAT 2 (20 mg Mucuna + 20 mg Ashwagandha + 20 mg Tribulus/kg BW). There was no significant difference found between the MAT1 and MAT2 groups while they showed significantly increased testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) levels when compared to the negative control. Significant increases in Nrf2/HO1 levels and decreases in NF-κB were detected in MAT groups similar to the decrease in serum and testis malondialdehyde (MDA) levels as compared to both controls. The sperm motility, count, and rate also significantly improved in both MAT groups, while ALT, AST, creatinine, ALP, and urea levels did not change in any of the groups. Oral consumption of MATs combination in male rats resulted in inhibition of NF-κB and MDA and also increased sex hormones with Nrf2-mediated HO-1 induction. MAT combinations may improve sexual functions by increasing levels of sexual hormones and regulation of NF-κB and Nrf2/HO-1 signaling pathways.

The present study was conducted to evaluate the mutagenic and antimutagenic potential of Cousinia thomsonii (CT) extract in bone marrow cells of male wistar rats using some important parameters like micronucleated polychromatic erythrocyte (MnPCE), mitotic index (MI), chromosomal aberrations (CA) and polychromatic erythrocyte to normochromatic erythrocyte ratio (PCE/NCE). 30 male rats of wistar strain were divided into 6 groups with 5 rats each group. Group 1 rats were taken as negative control having free access to distilled water and rat feed. Group 2 rats were taken as positive control treated with mutagen cyclophosphamide (CP) at dose of 60 mg/kg b wt. for 2 days. Group 3 and 4 were treated with CT extract at dose of 100 and 200 mg/kg b wt. for 20 days. Group 5 and 6 were treated with 100 and 200 mg/kg b wt of CT extract for first 18 days and for last 2 days with CP at dose concentration of 60 mg/kg. It was found that rats treated with CT extract alone did not produce any significant changes in MnPCE, PCE/NCE ratio, CA and MI when compared with control treated rats (group 1). However in group 5 and 6 rats treated with CT extract in combination with CP a protective effect was observed against the cyclophosphamide induced cellular mutagenicity. In concluding remark Cousinia thomsonii was found to show antigenotoxic potential and also produce protective antimutagenic effects against CP induced chromosomal damage.
