Abstract

BACKGROUND: Parkia speciosa seeds have been reported to have an anticancer property due to the presence of various antioxidant compounds. Since the potential uses of P. speciosa for the tongue cancer has not been clearly disclosed, we conducted a study to investigate anticancer properties of P. speciosa seed ethanol extract (PSSEE) as well as its effect on cardiac cells.METHODS: Tongue cancer rat model were treated with/without Doxorubicin and various concentrations of PSSEE. After treatment, tongue and heart samples were collected and processed further for histological examinations. Tongue epithelium thickness and damaged heart tissues was observed by HE staining, while tongue cancer cell proliferation was assessed by Ki-67 immunohistochemistry. Analyses were performed under an upright light microscope to measure tongue epithelium thickness, state of cancer cell proliferation, and degree of heart tissue damage.RESULTS: Addition of 400 mg/kg body weight (BW) PSSEE to 4.6 mg/kg BW Doxorubicin reduced the average tongue epithelial thickness and Ki-67+ cells number. Upon addition of PSSEE to Doxorubicin, the damage of heart tissue was reduced in a concentration dependent manner. Among all groups, the group of tongue cancer treated with 4.6 mg/kg BW Doxorubicin and 400 mg/kg BW PSSEE had the lowest percentage as well as the lowest degree of heart tissue damage.CONCLUSION: Since addition of PSSEE to Doxorubicin reduced epithelial thickness, number of Ki-67+ cells and heart tissue damage, PSSEE could be a potential co-chemotherapeutic agent for Doxorubicin toward tongue cancer.KEYWORDS: Parkia speciosa, Doxorubicin, tongue cancer, epithelial thickness, Ki-67, cardiotoxicity, co-chemotherapy

Abstract

BACKGROUND: Obesity has been widely reported to be associated with loss of kidney function. The efficacy of β-1,3/1,6-D-glucan as a traditional medicine for the improvement of inflammation and vascular status in obesity has known. However, there have been no further studies that prove the effect of β-1,3/1,6-D-glucan in inhibiting kidney injury as an impact of chronic inflammation exposure on obesity. This study aimed to investigate the impact of β-1,3/1,6-D-glucan from mycelia extract supplementation on renal function improvement based on serum nitric oxide (NO), ureum, and creatinine levels.METHODS: This was a randomized control trial study involving 69 obese subjects treated with or without β-1,3/1,6-D-glucan supplementation. The serum NO, ureum, and creatinine levels of the subjects were measured at baseline and post-treatment using enzyme-linked immunosorbent assay (ELISA) and then statistically analyzed with paired T-test.RESULTS: Although slightly decrease, no significant difference was found between the ureum and creatinine level at the baseline and and post-treatment (p=0.806, p=0.306, respectively) after β-1,3/1,6-D-glucan supplementation. Serum NO levels significantly decrease after treatment of β-1,3/1,6-D-glucan (p<0.001).CONCLUSION: Current study concludes that β-1,3/1,6-D-glucan from mycelia extract does not significantly lower urea and creatinine level, however, significantly able to reduce the serum NO concentration in obese subjects. Therefore, β-1,3/1,6-D-glucan from mycelia extract might have the renal protection potential in obesity.KEYWORDS: β-1,3/1,6-D-glucan, Ganoderma lucidum, renal function improvement, obesity

Abstract

BACKGROUND: Aquilaria malaccensis has been consumed as herbal medicine, and in vitro study showed that the leaf extract possesses high antioxidant activities. A brief preliminary study indicated that A. malaccensis showed a promising immunomodulatory activity when evaluated using latex beads. This current study aimed to evaluate the immunomodulatory activity of A. malaccensis leaf extract on the macrophage, which was challenged with pathogenic bacteria Staphylococcus aureus.METHODS: Bioactivity was determined by evaluating the phagocytic capacity of macrophages isolated from Mus musculus against S. aureus. First, the cytotoxicity of extracts on macrophages was evaluated using MTT assays, and the IC50 value was used to determine the dose of immunomodulatory assays. The highest toxicity was observed on chloroform extract with an IC50 value of 111.4 µg/mL. Therefore, the treatment was 100 and 50 µg/mL. Two parameters, including the phagocytic activity and phagocytic capacity of macrophages infected with S. aureus, were used to evaluate immunomodulatory activity. The analysis of variance was done at p<0.05 to determine the significant difference among treatments.RESULTS: Chloroform and ethanol extracts at a 50 µg/mL concentration showed the best results with the phagocytic activity of 82.33%±9.61% and 80.33±1.53%. The ethyl acetate showed lower phagocytic activities of 70.67±1.53. All extracts significantly increased phagocytic activity and phagocytic capacity, and the results differed significantly between negative and positive controls. Thin-layer chromatography indicated that the extract contained terpenoid, flavonoid, phenolic, and tannin.CONCLUSION: A. malaccensis leaf extracts showed immunomodulatory activity. Both chloroform and ethanol extracts showed comparable activity, while the ethyl acetate extract was lower. The extracts contained diverse bioactive compounds that may support activating macrophage cells for immunomodulatory activity.KEYWORDS: Aquilaria malaccensis, immunomodulator, phagocytosis, macrophages, Staphylococcus aureus
