Abstract

BACKGROUND: Central obesity has a close association with inflammation and the state of bone mass. Osteopenia is an abnormal condition of bone density. Bone mass density is influenced by several factors, such as 25(OH)D, parathyroid hormone (PTH), calcium (Ca) and phosphorus (P). The aim of this study was to evaluate the role of PTH-25(OH)D and Ca-P ratio as risk factors for osteopenia in women with central obesity.METHODS: A cross-sectional study was conducted in September 2020 to March 2021. The total subjects were 130 women aged 25-50 years old with central obesity. The diagnosis of osteopenia was done using dual X-ray absorptiometry (DXA) to measure bone mineral density. Enzyme linked fluorescent assay (ELFA) method was done to measure PTH and 25(OH)D levels, ion selective electrode method to measure Ca, and photometer method to measure P level. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value and calculated prevalence ratio (PR) for osteopenia risks, followed by logistic regression analysis.RESULTS: The PR of PTH level was 10.18 (95% CI: 1.15–5.85; p=0.01); the PTH-25(OH)D ratio was 5.12 (95% CI: 1.13–23.19; p=0.04); Ca level was 6.0 (95% CI: 1.33–27.14; p=0.02) and Ca-P ratio was 4.89 (95%CI: 1.33–17.97; p=0.02). The PR for PTH together with Ca level was 18.71 (95% CI: 2.17–160.40; p=0.008).CONCLUSION: The PTH-25(OH)D ratio and the Ca-P ratio are risk factors for the incidence of osteopenia in women with central obesity. A high PTH-25(OH)D ratio and a high Ca-P ratio would have a higher risk of developing osteopenia in this population.KEYWORDS: CRP, PTH-25(OH)D, Ca-P, osteopenia, central obesity, women

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

Abstract

BACKGROUND: Many hypotheses regarding the pathophysiology of enterocolitis in aganglionic megacolon or Hirschsprung disease (HSCR) has been proposed. Paneth cells are columnar intestinal epithelial cells that have an important role in maintaining of intestinal homeostasis as a bactericide. Since enterocolitis in HSCR may have association with Paneth cells metaplasia and hyperplasia, current study investigated Paneth cells metaplasia and hyperplasia in the sigmoid colon of HSCR rat model and its products, namely a-defensins and IL-1b, in the sigmoid colon tissues.METHODS: Aganglionosis-induced and control Sprague-Dawley rats were euthanized on Day (D)-7, -14, -17, -19, -21, -23, -25, and -28. Sigmoid colon tissue was isolated at each time point, and degree of enterocolitis as well as Paneth cells metaplasia and hyperplasia were analyzed by Hematoxylin-eosin staining, then protein levels of a-defensins and interleukin (IL)-1b were determined by enzyme-linked immunosorbent assay (ELISA).RESULTS: Enterocolitis scores increased with time. The Paneth cells metaplasia and hyperplasia were observed on D14 until D28 (p<0.01 vs. control group) followed by an increased in the levels of IL-1b. The levels of a-defensins protein expression were initially increased (D7-D14; p<0.01 vs. control group) but then undergo reciprocal changes on D19 until D28 (p<0.01 vs. D7 and D14). Positive correlations between the degree of enterocolitis and Paneth cells number were detected in the sigmoid colon (r=0.42).CONCLUSION: Paneth cells underwent metaplasia and hyperplasia in the sigmoid colon of HSCR rats corresponding to an increase in the degree of enterocolitis, but not followed by an increase in the level of a-defensins as well as IL-1b, suggesting that there is an involvement of Paneth cells in the pathophysiology of enterocolitis due to HSCR.KEYWORDS: Hirschsprung, enterocolitis, defensins; metaplasia, Paneth cell, animal model

Abstract

BACKGROUND: Indonesia's tropical forest is home to around 80% of the world's medicinal plants. One of these is Zingiber purpureum, which have traditionally been used to treat joint discomfort, the common cold, and jaundice. The rhizomes of this plant have been suggested to possess antibacterial action in the treatment of infections. In this study, Z. purpureum was screened for antibacterial activity against 13 bacteria (Gram-positive and Gram-negative).METHODS: Z. purpureum rhizomes were obtained and the distillated extracts were made to generate essential oil. The minimum inhibitory concentration (MIC) and Kirby Bauer disk diffusion methods were used to determine the antibacterial activity.RESULTS: All bacteria activity were inhibited by the essential oil of Z. purpureum at concentrations ranging from 2.5 vol% to 10 vol%. However, several bacterias (Escherichia coli, Pseudomonas aeruginosa, and Enterobacter cloacae) were inhibited at the lowest concentration (0.63 vol %), with the inhibition zones ranging from 6.7 mm to 8.0 mm. Meanwhile, the widest inhibition zone (13.3 mm) was reported on E. cloacae at 10 vol% concentration.CONCLUSION: A 10 vol% Z. purpureum rhizome extract inhibits Gram-positive and Gram-negative bacteria, particularly those that are resistant to a variety of antibiotics.KEYWORDS: Zingiber purpureum, antibacterial agents, susceptibility test, infection

Abstract

BACKGROUND: Purple  sweet  potato  yogurt (PSPY) is a funtional food which is rich in anthocyanin and probiotics. However, the currently available data on its potentially protective effect on anthropometry, lipid metabolism, oxidative stress, and pro-inflammatory markers is very minimal, especially in mice. This study was performed to investigate those effects on balb/c mice models (Mus musculus) given a high-fat diet (HFD).METHOD: Balb/c mice were treated with or without standard diet, HFD, ethanol extract, yogurt, and PSPY according to the group. The changes of anthropometry were analyzed using Lee Index. After three months, the interscapular brown adipose tissue (iBAT) was morphologically observed with hematoxylin and eosin (H&E) staining. The blood serum was used for evaluation using cholesterol oxidase-peroxidase aminoantypirin (CHOD-PAP) for lipid profile, enzyme-linked immunoassay (ELISA) for tumor necrosis factor (TNF)-α and interleukin (IL)-6, and thiobarbituric acid reactive substance (TBARS) procedure for malondialdehyde (MDA).RESULT: Lee Index revealed a decrease in time (p<0.0001). The PSPY group showed a decrease in iBAT weight (p<0.05), lipid profiles including LDL (p<0.05) and total cholesterol (p>0.05), TNF-α and IL-6 (p>0.05), and MDA (p>0.05). Adipocytes’ density showed a significant increase (p=0.001). CONCLUSION: This research finding indicates that PSPY affects lipid metabolism and has a potential protective effect of reducing systemic inflammation and oxidative stress.KEYWORDS: anthocyanin, high-fat diet, lee index, lipid metabolism, oxidative stress, purple sweet potato yogurt, systemic inflammation

Abstract

BACKGROUND: Interaction between estrogen and estrogen receptor (ER) takes part in the regulation and differentiation of breast tumorigenesis. Some ERα polymorphisms, including ERα rs3798577, are reported to be associated with the risk and aggressiveness of breast carcinoma since the site was reported to be targeted by microRNA, which can further modulate the ERα expression. Hence, this study was conducted to disclose the possible role of ERα SNP rs3798577 on breast carcinoma patients.METHODS: Samples were taken from the post-mastectomy breast carcinoma tissues of female patients and screened based on the completeness of medical and histopathological records. DNA isolation was proceeded using real time-polymerase chain reaction (RT-PCR) then analyzed for high resolution melting (HRM). The nucleotide base sequence was then analyzed based on rs3798577 ERα polymorphism. ER immunohistochemistry test was carried out and counted quantitatively based on the staining intensity and the percentage of the stained cells.RESULTS: Out of 65 samples, there were 33 samples as wild type and 32 samples as variant type. Most variant and wild type had >80% ERα percentage. Most variant type had middle ERα intensity, while wild type had strong ERα intensity. Higher percentage of variant type (52.2%) was found with weak ERα histoscore, meanwhile higher percentage of wild type (52.4%) was found with strong ERα histoscore, but not significant (p=0.725).CONCLUSION: ERα rs3798577 variant type had a lower ERα intensity and weaker ERα histoscore compared to the wild type, suggesting that ERα rs3798577 polymorphism might play a role in breast carcinoma risk determination.KEYWORDS: breast cancer, ERα, rs3798577, polymorphism, immunoexpression

Abstract

BACKGROUND: Caffeic acid has been reported to activate caspases in MG-63 osteosarcoma cells, which can lead to apoptosis via both extrinsic and intrinsic apoptotic pathways. Translocation of protein kinase C delta (PKCδ), which reduces mitochondrial membrane potential (ΔΨm), is involved in apoptosis. The role of PKCδ translocation and ΔΨm alteration in caffeic acid-induced MG-63 cell apoptosis are largely unknown. Present study investigated the effect of caffeic acid on PKCδ translocation and ΔΨm in MG-63 cells.METHODS: MG-63 cells were cultured and starved, followed by pretreatment with or without Z-VAD-FMK and treatment with or without 10 μg/mL caffeic acid. MG-63 cells were collected, lysed, and processed to obtain cytosolic and mitochondrial fractions. Each fraction was subjected to immunoblotting analysis by using anti-PKCδ antibody. Mitochondrial membrane potential (ΔΨm) was measured using flow cytometry.RESULTS: Cytosolic PKCδ levels were higher than mitochondrial PKCδ levels in untreated and 1 h caffeic acid treatment groups. Inversely, cytosolic PKCδ levels were lower than the mitochondrial PKCδ levels after 6 and 12 h caffeic acid treatment. By Z-VAD-FMK pretreatment, cytosolic PKCδ levels were higher than mitochondrial PKCδ after 6 and 12 h caffeic acid treatment. After 6 h treatment with caffeic acid, ΔΨm was slightly shifted. More shifting occurred in MG-63 cells treated with caffeic acid for 12 h. The ΔΨm shifting was inhibited by Z-VAD-FMK pretreatment.CONCLUSION: Caffeic acid could trigger apoptosis of MG-63 osteosarcoma cells by inducing PKCδ translocation to mitochondria and reducing ΔΨm, which might cause MMP.KEYWORDS: caffeic acid, MG-63, osteosarcoma, PKCδ, mitochondrial membrane potential, mitochondrial membrane permeabilization, Z-VAD-FMK

Abstract

BACKGROUND: Premature Rupture of Membranes (PROM) is significantly linked to the infections-related maternal deaths. In the inflammatory process, the influencing stressor will stimulate the activation of Nuclear Factor Kappa B (NF-κB) and Receptor of Advanced Gyclation End product (RAGE). Yet up to date, the expression of NF-κB and RAGE in pregnant women with PROM are still rarely studied. Therefore, this study aimed to observe the differences of NF-κB and RAGE expression from PROM and non-PROM subjects.METHODS: This was a cross-sectional study involving 20 PROM subjects and 20 non-PROM subjects with infections and complications. Samples from the fetal membrane tissue of subjects were obtained and put into paraffin block preparation for the determination of NF-κB and RAGE expression. The detection of NF-κB and RAGE expression was conducted using immunohistochemical staining and observed under an upright light microscope. The expressions were later calculated using ImageJ software. RESULTS: Both NF-κB and RAGE expression were found to be higher in PROM subjects compare to the non-PROM subjects. The median of NF-κB in PROM and non-PROM subjects were 32.47±1.22 and 5.59±1.09, respectively (p=0.000). While the median of RAGE in PROM subjects was 53.58±3.46, and in non-PROM subjects was 11.64±2.49 (p=0.013).CONCLUSION: There is significant difference between NF-κB and RAGE expression in fetal membranes of PROM and non-PROM subjects. Therefore, the increased of NF-κB and RAGE expression can be used as a potential marker to detect complication of PROM.KEYWORDS: premature ruptures of membrane, non-premature ruptures of membrane, expression of NF-κB
