The ratio of xylooligosaccharide to ferulic acid affects faecal ferulic acid content, short chain fatty acid output, and gut stress

There have been contradicting observations regarding the prebiotic efficacy of feruloylated oligosaccharides (FOs) extracted from different varieties of cereals with varying oligosaccharides and ferulic acid (FA) levels. The present study was performed to determine whether the mass ratio of xylooligosaccharide (XOS) to FA influences their combined effects on faecal FA content, short chain fatty acid (SCFA) output, and gut stress of d-galactose-treated aging rats. The results show that there was no significant difference in the faecal FA levels of rats fed with 5:1 and 10:1 XOS:FA diet, although the FA level in the 5:1-supplemented diet was twice as much as in the 10:1 diet. More utilisation of FA decreased butyric acid and SCFA output in the faeces for diet 5:1 compared with diets 10:1 XOS:FA or XOS alone. Furthermore, compared with 10:1 XOS:FA or XOS alone treatments, the 5:1 XOS:FA diet resulted in increased 1-diphenyl-2-picrylhydrazyl activity and higher ratios of Bifidobacterium or Lactobacillus to Escherichia coli (P < 0.05), while not increasing the number of probiotic Bifidobacterium and Lactobacillus. These findings suggest that under the specific stress level set for this study, the sufficient amount of FA added to XOS (5:1) can stimulate FA utilisation to modify gut redox balance, while reducing faecal SCFA output.

Curative impacts of Ethanoic Extract of Laportea aestuans (L) Chew in Aspirin-Induced Ulcerative compromise in Male Rats

Toxicity of Non-steroidal anti-inflammatory drugs (NSAIDs) are being reported with its diverse effect in the host resulting in ulcerations. Ulceration was induced orally using aspirin. Twenty-four male Wistar rats were used for this study (120-150g). Rats were divided into 6 groups with each group containing 4 rats. Rats were pre-treated orally with cimetidine, a reference drug. Group 1 rats orally received 1% gum acacia solution as the control group, Group 2 rats orally administered 25 mg/kg aspirin and served as the ulcerated, untreated group, rats in groups 3 and 4 were pre-treated orally with 200 mg/kg and 400 mg/kg respectively for 3 days while rats in groups 5 and 6 were pre-treated orally with 50 mg/kg cimetidine and 50 mg/kg catechin respectively for 3 days. The result of this study shows that the ulcerated, untreated rats showed increased concentrations of The result of this study shows that the ulcerated, untreated rats showed increased concentrations of acid output, pepsin activity with a concomitant decrease in pH values, and mucin content compared to control group but pre-treatment with different doses, cimetidine and catechin reversed these observations. Activities of superoxide oxidase were decreased in the ulcerated, untreated group with a concomitant increase in lipid peroxidation concentration but pre-treatment with different doses, cimetidine and catechin reversed these observations. In conclusion, the ethanoic extract of L. aestuans can be said to be used therapeutically agaisnt aspirin-induced gastric ulcer which is due to the presence of bioactive compounds in the plant. as an anti-ulcerogenic agent against aspirin-induced gastric ulcer which is due to the presence of phytochemicals in the plant.

Is There an Association between Variceal Bleed and Helicobacter pylori Infection in Cirrhotic Patients with Portal Hypertension?

Objectives: The objective of this study was to find the association of H. pylori in patients with variceal bleeding as well as rebleeding in cases of cirrhosis with portal hypertension. Methods: This was a prospective cohort of patients with bleeding esophageal varices. The primary outcome was correlation between prevalence of H. pylori and the incidence of bleeding/ rebleeding from varices and with encephalopathy. The secondary outcome were correlation between the site of bleeding with H. pylori infection and the association of pepsinogen I & II and the ratio of pepsinogen I/II with bleeding. Results: A total of 190 patients were assessed for eligibility, out of which 159 patients were included in this study. 124 out of 159 patients (77.9%) had alcohol-related liver disease. 8 out of 159 patients had HBV-related liver disease. 7 patients with varices had neither bled at presentation nor did bleed in the follow-up period. A total of 78 out of 159 (49.05%) patients were H.pylori-infected. Patients with esophageal varices [Adjusted Risk (AR)=0.7] and H.pylori infection (AR=0.7) had a lower risk of variceal rebleeding. Among the patients negative for H.pylori, pepsinogen I was higher in patients with rebleeding (30.7 vs 14.4; p<0.001). Among H.pylori positive patients, the ratio of pepsinogen I/II was higher in patients with rebleeding (2.9 vs 1.3; p=0.023). Conclusion: H.pylori infection was associated with a lower risk of rebleeding in cases of cirrhosis with portal hypertension. Irrespective of the status of H.pylori infection, rebleeding was associated with more gastric acid output demonstrated by the level of pepsinogen.

Gastric mucosal function in portal hypertensive gastropathy secondary to schistosomal hepatic fibrosis: effect of sclerotherapy

Gastric mucosal function in portal hypertensive gastropathy secondary to schistosomal hepatic fibrosis [SHF] was evaluated. Group I comprised 20 patients with no bleeding;10 had portal hypertensive gastropathy [PHG]. Group II comprised 20 patients with bleeding. Free acidity, total acidity, basal acid output, serum pepsinogen I, gastric mucosal blood flow [GMBF] and gastrin were significantly lower in group II, whereas serum gastrin and somatostatin staining were significantly higher. No histopathological changes were noted between both groups, In conclusion, bleeding caused by SHF results in hypoacidity, hypergastrinaemia and hypopepsinogenaemia. Estimated GMBF distinguishes patients with PHG and those who are bleeders

POS1144 SERUM URIC ACID TO CREATININE RATIO IS ASSOCIATED WITH URINARY URIC ACID EXCRETION IN PATIENTS WITH GOUT

Background:Underexcretion of uric acid is the dominant mechanism leading to hyperuricemia [1] and the 24-hour urinary uric acid excretion is an important measurement. However, it is inconvenient due to accurate timing and complete collection of the specimen.Objectives:The aim of this study was to investigate the relationship between serum uric acid to creatinine ratio (sUACR) and 24-hour urinary uric acid excretion in gout patients.Methods:A total of 110 gout patients fulfilling 2015 ACR/EULAR classification criteria from Guangdong Second Provincial General Hospital from January 2019 to January 2021 were retrospectively enrolled in this study. Patients were divided into underexcretion group (<3600 μmol/24h) and non-underexcretion group (≥3600 μmol/24h). The correlation between sUACR and 24-hour urinary uric acid excretion was analyzed by the Pearson’s correlations analysis. Receiver operation characteristic (ROC) curves were performed to assess the utility of sUACR for discriminating between underexcretion group and non-underexcretion group. Furthermore, the risk factors of uric acid underexcretion were evaluated using binary logistic regression analysis.Results:sUACR in the underexcretion group was significantly lower than the non-underexcretion group (p=0.0001). Besides, sUACR was positively correlated with 24-hour urinary uric acid excretion (r=0.4833, p<0.0001). Furthermore, ROC suggested that the area under the curve (AUC) of sUACR was 0.728, which was higher that of serum uric acid and creatinine. The optimal cutoff point of sUACR was 5.2312, with a sensitivity and specificity of 71.9% and 67.9%. Logistic analysis results revealed that decreased sUACR (<5.2312) was an independent risk factor of underexcretion of uric acid (OR =5.510, 95% CI: 1.952-15.550, P=0.001).Conclusion:sUACR is lower in gout patients with underexcretion of uric acid and may serve as a useful and convenient marker of assessing underexcretion of uric acid in gout patients.References:[1]Perez-Ruiz F, Calabozo M, Erauskin GG, Ruibal A, Herrero-Beites AM.

Dihydroquercetin (taxifolin) attenuates dexamethasone activity on prostaglandin E-2 but potentiates thromboxane-A2 action in gastric acid secretion in wistar rats

The activity of dexamethasone and taxifolin {(2R, 3R)-2-(3, 4-Dihydroxyphenyl)-3,5,7-trihydroxy-2,3-dihydrochromen-4-one}supplementation on prostaglandin E2 and thromboxane A2 in gastric acid secretion and anti-ulcer was studied. Twenty male Wistar rats (180g-200g body weight) were used. The rats were randomly selected into four groups containing 5 rats each. Group 1 was the control group fed on normal rat feed. Group 2 received 3mg/kg of Dexamethasone (intraperitoneally) at one day interval. Group 3 received 3mg/kg of Dex. intraperitoneally and 1mg/kg body weight of taxifolin orally while group 4 received 1mg/kg body weight of taxifolin. At the end of 6 weeks, basal and peak gastric acid output was measured by continuous perfusion of rats stomach under anaesthesia with normal saline at the rate of 1ml/min. Gastric acid, mucus secretion, ulcer index, PGE-2 and thromboxane A2 activity were determined according to standard procedures. Results showed a significantly (p<.05) decreased prostaglandin and mucus secretion level and a raised thromboxane concentrations and gastric acid output in dexamethasone administration. Taxifolin significantly (p<.05) lowered thromboxane A2 concentration in Dex treatment while increasing the prostaglandin E2 level. We conclude that Taxifolin decreases dexamethasone- induced gastric acid secretion, increases prostaglandin activity but reduces thromboxane concentration.

Concentration Enrichment of Fermentation Derived Acetic Acid: Transport Modeling of Forward Osmosis-Nanofiltration Integrated System

Forward Osmosis (FO)-Nanofiltration (NF) integration as the final product polishing step enables high concentration of acetic acid output through continuous dehydration of fermentation derived product. A mathematical transport model has been developed based on external and internal concentration polarization modulus of FO and extended Nernst–Plank equation for NF to capture the flux and rejection trends from those membranes. The modular designed production scheme ensured high flux (45 Lm−2 h−1), concentration (962 g L−1) and purity (>98 %) of acetic acid under non-neutralization condition. Excellent performance of the model is reflected in low relative error (<0.05), high Willmott d-index (>0.97) and high correlation coefficient (>0.98).

Levels of proteins and immunoglobulins in rabbit blood during Рassalurosis

The purpose of our work was to determine the influence of Passalurus ambiguus on proteinogram and the level of immunoglobulins in the blood of rabbits. Analog groups of male rabbits of 3–5 months of age were selected for the experiments. Intensity of invasion was determined by the method of the MacMaster. By spectrophotometric method in the blood of animals there was determined: the content of total protein, albumin, globulin fractions, the level of IgA, IgG, IgM — discrete deposition method according to M. Kostina. Rabbits with pasalurosis have different levels of invasion intensity (II): low (II = 276.47 ± 43.33 eggs/g of feces), high (II = 2,446.67 ± 422.11 eggs/g of feces) — II and medium (II = 1,293.75 ± 275.80 eggs/g of feces) — III research groups. We did not find eggs in the control group. The total protein content was significantly (p < 0.001) higher — from 1.38 times to 1.66 times compared with healthy ones, due to an increase in the content of globulins from 2.08 times (p < 0.001) to 2.26 times (p < 0.001), which led to a decrease in the protein ratio from 2.16 times (p < 0.001) to 3.29 times (p < 0.001) in sick animals with different II. We recorded a high content of γ-globulins almost 1.4 times in these animals compared to healthy ones. We observed a high content of β-globulins and α2-globulins by 6.70% and 7.05% (p < 0.01) and 5.15% and 3.99% (p < 0.05) in animals II and III experimental groups in comparison with control group. A decreased level of uric acid from 4.77 times (p < 0.001) to 6.19 times (p < 0.001) in rabbits with passalurosis is probably due to a violation of the process of its formation in the liver against the background of an increase in acid output through the intestines and kidneys. The creatinine level in experimental rabbits was significantly higher in groups I, II, III by 42.64% (p < 0.001), 46.49% (p < 0.001) and 44.42% (p < 0.001), respectively, compared with the control. IgA and IgG levels were high (p < 0.001) in comparison to healthy rabbits: 2.22 and 2.16 times (in animals with low II), 1.51 and 1.85 times (in animals with high II). We observed a significant (p < 0.001) high level of IgM against the control 1.58 times, 1.82 times and 1.70 times, respectively, in groups I, II, III of infected rabbits. The content of total protein, globulins, γ-globulins, IgA, IgG, IgM and creatinine were significantly higher (p < 0.001) in the blood of sick rabbits than healthy ones. We observed significant changes in the proteinogram of rabbits with high levels of II. These changes indicate an increase in the body’s immune defense under the influence of Passalurus ambiguus. We found a decreased level of uric acid and a protein coefficient due to the low percentage of albumin in sick rabbits. This is possibly due to a violation of the process of their formation in the liver against the background of increased output
