Abstract

BACKGROUND: Some of colorectal cancers (CRCs) are familial, however, heterozygote relatives have approximately 80% lifetime risk of cancer. Risk assessment of CRC’s family could be calculated by direct measurement of mRNA gene expression and Bayesian theorem which is modifying initial background of pedigree risk with additional conditional information. This application has not been reported.METHODS: The cross-sectional translational sequential studies were performed: (1) adenomatous polyposis coli (APC) and MutS homolog (MSH)2 mRNA quantitative RT PCR gene expressions in tissue and whole blood CRC patients; (2) gene expression was determined in matched controls; and (3) pedigree and Bayesian analysis was calculated in the patient’s family of Proband.RESULTS: Fourty CRC and 31 control subjects were enrolled. The mean blood APC level control’s group was 13,261±670 fold-change (fc) and blood MSH2 level was 12,219±756 fc. The cut-off points for hereditary APC was 12,195 fc and MSH2 was 11,059 fc. The mean APC blood level in CRC subject was 11,578±2,638 fc and MSH2 blood level was 11,411±2,912 fc. There were significant differences APC and MSH level between tissue and blood level in CRC. Eight of 40 CRC subjects had a history of familial CRC. Four patients and 10 Probands were available for recurrence risk evaluation of pedigree analysis, RNA PCR quantitative and Bayesian calculation.CONCLUSION: There was determined a cut-off point of hereditary mRNA quantitative expression. The APC and MSH2 levels in CRC subjects were significantly lower than controls. Bayesian analysis allowed for the calculation of relative risk in CRC family members and considered in clinical practice.KEYWORDS: hereditary CRC, APC gene, MSH gene, Bayesian analysis

Abstract

BACKGROUND: Uric acid is a final result of purine catabolism, the enzymatic reactions in the body cells from amino acids or ribonucleotide dinucleotide. Peperomia pellucida L. (P. pellucida), Acalypha indica L. (A. indica) and Momordica charantia L. (M. charantia) are plants which have efficacy to reduce levels of uric acid excess. The aim of this research is to find out the effect of ethanol extract of P. pellucida, A. indica and M. charantia in preventing the formation of uric acid excess by inhibiting the action of the enzyme xanthine oxidase and comparing the inhibition activity of xanthine oxidase on treatments.METHODS: The study design is experimental and conducted using the enzyme xanthine oxidase, xanthine (substrate), pH 7.5 phosphate buffer, samples (P. pellucida, A. indica and M. charantia ethanol extracts) and HCL as reaction breaker. Inhibition of xanthine oxidase was determined enzymatically and unreacted xanthine was measured by UV spectrophotometer at 290 nm. The data were expressed as percent inhibition and the inhibitory concentration (IC)50 were determined using linear regresion of inhibition activity vs. concentration.RESULTS: The IC50 of P. pellucida, A. indica and M. charantia ethanol extracts in inhibiting xanthine oxidase were 19.5 ppm, 77.6 ppm and 17.8 ppm, respectively. IC50 of allopurinol was 1.99 μg/ml, and negative control (combination of enzyme and substrate) has absorbance value of 0.75026.CONCLUSION: Ethanol extract of M. charantia showed the most potent inhibition toward xanthine oxidase compared to the other two extracts.KEYWORDS: xanthine oxidase, Peperomia pellucida L., Acalypha indica L., Momordica charantia L.

Abstract

BACKGROUND: Malnutrition is a global health concern that results in changes in nutritional status, as indicated by alterations in phenotypic markers, hematological and biochemical parameters, and increased susceptibility to infection, as shown by decreased interleukin (IL)-2 levels. Andrographolide, the active component of Andrographis paniculata, stimulates the immune system and exhibits antibacterial and antiviral activity. Therefore, A. paniculata may serve as a potential adjuvant therapy for malnutrition. This study was conducted to analyze the effect of A. paniculata as an immunomodulator against malnutrition with characteristics of environmental enteric dysfunction (EED) and a low-protein diet by examining phenotypic markers, hematological, biochemical, and IL-2 levels.METHODS: Forty-five male Wistar rats were divided into seven groups. They were fed either a standard or a low-protein diet before receiving oral administration of various concentrations of A. paniculata leaf extract (APLE). APLE was administered 21 days after the initial low-protein diet. Hematological, biochemical, and phenotypic markers were assessed to determine the nutritional status of the rats. The protective effects of APLE were evaluated by measuring IL-2 levels using enzyme-linked immunosorbent assay (ELISA).RESULTS: Malnourished rats exhibited slow body growth, physical and behavioral changes, reduced leukocyte count, total protein, albumin, cholesterol, and villi length. Malnourished rats treated with APLE showed a more effective and significant increase in IL-2 levels, with higher concentrations of APLE resulting in higher IL-2 levels.CONCLUSION: APLE, in a concentration-dependent manner, can increase IL-2 levels, suggesting that APLE may have potential protective effects in a rat model of malnutrition.KEYWORDS: Andrographis paniculata, environmental enteric dysfunction, interleukin (IL)-2, low protein, malnutrition
