Poultry meat consumption is increasing worldwide but the overuse of antimicrobials for prevention and treatment of diseases has increased antimicrobial resistance (AMR), triggering a major public health issue. To restrict AMR emergence, the government supports the optimization of natural products that are safe and easy to obtain with minimal side effects on poultry, humans, and the environment. Various studies have explored the potential of herbs in animal health for their antiviral, antibacterial, antifungal, antiparasitic, immunomodulatory, antioxidant, and body weight gain properties. Therefore, this study reviewed plants with potential application in avian species by summarizing and discussing the mechanisms and prophylactic/therapeutic potential of these compounds and their plant origin extracts.

This research aims to identify the effects of the administration of a black rice bran diet on colorectal cancer in dextran sodium sulfate and azoxymethane-induced BALB/c mice. The research was conducted on three groups consisting of eight Balb/c mice: two groups were fed with carcinogens, and the third group, referred to as the normal group, was supplied with Isotonic NaCl 0.9% intraperitoneally. One group fed with carcinogens was supplied a standard AIN 1993 M diet modified with black rice bran as a substitute of fibre source, while the other two mice groups were fed the standard diet (AIN-93M) containing cellulose fibre. At the 17th week, all mice were euthanized; their colonic sections were taken for histopathological evaluation, and cecum for short-chain fatty acids concentration, total lactic acid bacteria, pH and β-glucuronidase activity evaluations. The results show an increase in the total lactic acid bacteria and short-chain fatty acids in the mice group fed with rice bran. Consequently, pH value and β-glucuronidase activity had decreased. Histopathological evaluation of mucosal tissue exhibited inhibition of the tumor growth rate in the mice groups fed rice bran compared to the group supplied with the standard diet. Furthermore, the proliferating cell nuclear antigen expression had decreased significantly, while expression of caspase-8 and caspase-3 had increased notably, in the group fed with a rice bran diet. These results suggest that black rice bran can effectively inhibit colon carcinogenesis. The potential of black rice bran as a source of fibre has not been studied in detail regarding the inhibition mechanism of colorectal cancer cells; further investigation in this field could provide valuable information about new strategies to prevent colorectal cancer. This strand of research is very important to developing preventive methods against cancer and promoting the concept of healthy products, including functional foods.

Background and Aim: Tumor disorder is one of the degenerative diseases that affected human and animals and recently is tend to increase significantly. The treatment of tumor diseases can be performed through surgical, chemotherapy, radiotherapy, biological substances, and herbs medicine. Typhonium flagelliforme leaves extract known to have an antiproliferation activity, while interferons (IFNs) one of the cytokines that first used as an antiviral agent was also known to have antitumor activity. Nowadays, the treatment of tumors using a traditional way, including the use of herbal substances, becomes popular. Some limitations of the antitumor activity due to resistant development of the cell to some substances were one of the problems on why the treatment of cancer was unsuccessful. This study aimed to elaborate the synergistic effect on the antiproliferation and anti-angiogenesis activities of the combinations between T. flagelliforme leaves ethanol extract and canine natural (natural canine IFN [nCaIFN]) and recombinant (recombinant canine IFN [rCaIFN]) IFNs on tumor-derived cell lines to find the new potential antitumor substances. Materials and Methods: The extraction of T. flagelliforme leaves was performed using the maceration method and followed by phytochemical screening assays. According to the result of LC50 by the brine shrimp lethality test, the dose used for T. flagelliforme extract was 120 ppm while the dose of IFNs was 102 U/ml. The tumor-derived cell lines (canine squamous cell carcinoma [CSCC], canine mammary gland benign mixed tumor/MCM-IPB-B3, and feline squamous cell carcinoma [FSCC]) and normal rabbit endothelial cells were cultured and maintained on Dulbecco's Modified Eagle's Medium DMEM/Ham-F12 medium supplemented with 10% fetal calf serum, antibiotic, and antifungal. The antiproliferation activity was assayed by calculated the total cell number after treated with the tested substances. The antiangiogenesis assay was performed using in vitro method on rabbit normal endothelial cells and in ovo using chicken chorioallantoic membrane (CAM). Results: The phytochemical screening test of the T. flagelliforme leaves ethanol extract indicated that the compound consisted of flavonoid, steroid, and tannin. The antiproliferation activity was increased in the combination of substances compared to the single exposure of each substance on all tested tumor-derived cell lines. There was no significantly different on the antiproliferation activity between a combination of T. flagelliforme with nCaIFN or rCaIFN in every single tested cell lines, but the comparison of this activity among the three tumor-derived cell lines seem that the antiproliferation activity is more effective on CSCC cell lines compared to the canine mammary gland benign mixed tumor and FSCC cell lines. A similar pattern of synergistic effect was also detected on the anti-angiogenesis activity in vitro using rabbit endothelial cells as well as in ovo assays. The most effective of the in vitro and in ovo anti-angiogenesis activity was observed on the combination substances between T. flagelliforme extract and rCaIFN compared to other treatments. Conclusion: There was a synergistic effect on the antiproliferation and antiangiogenesis activities of the combination between T. flagelliforme and canine IFNs (natural and recombinant) and this result could be developed as another alternative on the cancer treatments.

The application of shade during plants’ growth significantly alters the biochemical compounds of the essential oil (EO). We aimed to analyze the effect of shade on the volatile compounds and biochemical activities of EO extracted from Curcuma xanthorrhiza Roxb. (C. xanthorrhiza) plants. Four shading conditions were applied: no shading (S0), 25% (S25), 50% (S50), and 75% shade (S75). The volatile compounds of EO extracted from each shaded plant were analyzed by gas chromatography–mass spectrometry. The antioxidant, antibacterial, and antiproliferative activities of EO were also investigated. We found that shade application significantly reduced the C. xanthorrhiza EO yield but increased its aroma and bioactive compound concentration. α-curcumene, xanthorrhizol, α-cedrene, epicurzerenone, and germacrone were found in EO extracted from all conditions. However, β-bisabolol, curzerene, curcuphenol, and γ-himachalene were only detected in the EO of S75 plants. The EO of the shaded plants also showed higher antioxidant activity as compared to unshaded ones. In addition, the EO extracted from S75 exerted higher antiproliferative activity on HeLa cells as compared to S0. The EO extracted from S0 and S25 showed higher antibacterial activity against Gram-positive bacteria than kanamycin. Our results suggest that shade applications alter the composition of the extractable volatile compounds in C. xanthorrhiza, which may result in beneficial changes in the biochemical activity of the EO.

Introduction: taro leaves (Colocasia esculenta (L.) Schott) have been reported to possess wound healing, anti-inflammatory, antibacterial and antioxidant activities. One of the factors that affect wound healing is infection in the wound, wherein the wound is infected by bacteria, especially Staphylococcus aureus that is mostly found in the oral cavity, the wound healing process will be hampered and become longer healed.The objective of this research was to analyze the efficacy of Colocasia esculenta (L.) Schott extract on the healing process of wounds contaminated with Staphylococcus aureus. Methods: This experimental study on Sprague dawley rats was carried out at the Teaching Veterinary Hospital, IPB . Twenty-four Sprague dawley rats were made with circular excision wounds with a diameter of 2 cm on the dorsum, and Staphylococcus aureus specimens were contaminated with a dose of 3.4x108 LAC. Rats were randomly divided into 2 groups. Group I was given a placebo, group II was given a 25% concentration of Colocasia esculenta (L.) Schott extract on the wound once a day. Four rats from each group were euthanized on days 3, 7, and 14. The number of neutrophils, macrophages, re-epithelialization and FGF-2 expression were measured by microscopic observation with visual field control, and comparative data were analyzed using the Mann-Whitney statistical test. Results: The number of neutrophils on day 7 of the Colocasia esculenta (L.) Schott leaf extract group was less than the control group (p=0.040). The number of macrophages on the 3rd day was more in the treatment group than the control group (p=0.032), and on the 14th day, the treatment group was less than the control group (p=0.040). Epithelial cells on the 14th day of the treatment group were more than the control group (p=.0.017). The level of FGF-2 expression on day 7 of the treatment group was higher than the control group (p=0.044). Conclusion: Application of extracts Colocasia esculenta (L.) Schott leaf is proven to be efficacious on day 7 for wound healing contaminated with Staphylococcus aureus bacteria.

Breast cancer is a sickness caused by abnormal cell growth in the breast. Mahkota Dewa fruit or god’s crown fruit products (Phaleria macrocarpa) contain flavonoids, alkaloids, polyphenols, and tannins associated with active compounds. This work directs to influence the potency of P. macrocarpa fruit as an antiproliferative agent against breast cancer cells (MCF-7 cells). The antiproliferative potency of P. macrocarpa fruit was proved by extracting and fractionating P. macrocarpa fruit using maceration. The cytotoxicity of extracts and fractions was determined using Brine Shrimp Lethality Test (BSLT). The antiproliferative potency against MCF-7 cells was tested using the hemacytometer approach. This work demonstrates the crude ethanol extract, n-hexane fraction, ethyl acetate fraction, and water fraction. The LC50 values in crude ethanol extract, n-hexane fraction, ethyl acetate fraction, and water fraction were 13.72 ppm, 147.55 ppm, 405.81 ppm, and 149. 07 ppm severally. Phaleria macrocarpa fruit has shown antiproliferation potency against MCF-7 cells. The maximum part of crude ethanol extract antiproliferative potency (56 ppm) effectively suppressed MCF-7 cell growth by 70. 9% while doxorubicin (100 ppm) by 46. 92%. This work confirms that crude ethanol extract of P. macrocarpa fruit interacts synergistically as an antiproliferative compound against MCF-7 cells.
