The AIN-93G feed was provided to the CHOW group, whereas the HMD and HMD+HRW groups received AIN-93G supplemented with 2% methionine to establish an HHcy model. In the HMD+HRW group, hydrogen-rich water (0.8 mmol/L hydrogen, 3 ml/animal, twice daily) was provided, and body weight data were systematically collected. Following six weeks of nutritional provision, plasma and liver specimens were collected and prepared for analysis. Plasma homocysteine (Hcy) and lipid analyses, as well as liver histological examinations, were conducted for each group. Expression of mRNA and the activity of key enzymes were found to be measurable in the liver concerning the Hcy metabolism pathway. The Hcy concentration in the blood of HMD rats was significantly elevated in comparison to the CHOW group rats, as evidenced by a statistically significant difference (P<0.005). Rat liver sections revealed an enlarged liver with signs of injury and fatty infiltration; the HMD+HRW group exhibited a substantial decrease in blood homocysteine compared to the HMD group, accompanied by diminished liver damage and increased activity/mRNA levels of key homocysteine metabolic enzymes, demonstrably different statistically (P<0.005). A noteworthy enhancement of liver health is observed in hyperhomocysteinemic rats subjected to high-methionine diets upon hydrogen administration, likely achieved through the stimulation of three metabolic pathways for homocysteine metabolism, thereby improving hepatic function and relieving non-alcoholic fatty liver disease.
This study sought to investigate the intervention effects of curcumin (Curc) on liver injury in mice subjected to a chronic alcohol addiction model. The curcumin-based study employed thirty Balb/c mice, randomly allocated to a control group, a model group, and three graded curcumin treatment groups (5 mg/kg, 10 mg/kg, and 15 mg/kg), with six mice in each group. The chronic alcohol addiction liver injury model was created using a 20% concentration of liquor. A daily dose of 2 ml of normal saline was provided to the mice in the control group. The model group mice were given 5 ml/kg of 20% liquor daily, while Curc treatment group mice received 5, 10, or 15 mg/kg of Curc suspended in 2 ml of saline daily for 35 days. The mice's well-being and the liver weight were carefully scrutinized. A comprehensive analysis of serum ALT, AST, ALP, liver TG, TC, HDL-C, LDL-C, MDA, SOD, GSH-Px, and NO levels was performed. A review of hematoxylin and eosin-stained liver tissue revealed the presence of pathological alterations. A statistically significant increase in liver mass and serum levels of ALT, AST, ALP, MDA, NO, TC, TG, HDL-C, and LDL-C was observed in the model group compared to the control group (P<0.005, P<0.001). Furthermore, significant reductions in SOD and GSH-Px activities were detected (P<0.005, P<0.001), accompanied by liver cell vacuolation, infiltration by inflammatory cells, and a significant increase in NF-κB and MAPK protein expression levels in the liver (P<0.001). In contrast to the model group, the Curc group exhibited significantly reduced levels of ALT, AST, ALP, MDA, NO, TC, TG, HDL-C, and LDL-C, while demonstrating significantly elevated SOD and GSH-Px activity (P<0.005, P<0.001). Adverse event following immunization By regulating the NF-κB/MAPK signaling cascade, curcumin proves effective in minimizing liver tissue injury.
The study investigates Mijian Daotong Bowel Suppository (MJDs) and its impact on a diphenoxylate-induced constipation model in male rats, with a focus on underlying mechanisms. Methods were employed on sixty male SD rats, randomly divided into four groups, blank, model, positive, and MJDs. Researchers created a constipation model using the compound diphenoxylate gavage method. The rats designated as blank and model received saline enemas, while the rats in the positive and MJDs groups received Kaisailu and honey decoction laxative suppositories, respectively, by enema, each day for ten days. During the modeling and administration process, the rats' body weight, fecal water content, gastric emptying rate (GER), and carbon ink propulsion rate (CIPR) were monitored. A study using hematoxylin-eosin (HE) staining investigated the impact of MJDs on pathological changes exhibited in the colon tissues of rats subjected to constipation. By employing an ELISA kit, the study investigated the relationship between MJDs and 5-hydroxytryptamine (5-HT) levels in the colons of rats experiencing constipation. Using immunohistochemistry, the influence of MJDs on the expression of aquaporins 3 (AQP3) and 4 (AQP4) in the colons of rats with constipation was investigated. see more Compared to the model group, the positive group displayed a substantial elevation in both fecal water content and colon 5-HT levels, and a significant reduction in the expression of AQP3 and AQP4 within the colon. The MJDs group demonstrated a significant increase in body weight, fecal water content, and colon 5-HT content, and a substantial decrease in the expression of AQP3 and AQP4 (P<0.005, P<0.001). In comparison to the positive control group, the MJDs group exhibited a substantial decrease in fecal water content, and a significant reduction in the expression levels of AQP3 and AQP4 within the colon tissue of the MJDs group (P<0.005 and P<0.001, respectively). The groups exhibited no statistically meaningful difference regarding gastric emptying rate. MJDs' effectiveness in treating constipation is potentially mediated by their role in bolstering 5-HT concentration and decreasing the expression of aquaporins 3 and 4 within the large intestine.
This study aims to explore the influence of Cistanche deserticola and its key compounds, Cistanche deserticola polysaccharide and Echinacoside, on the gut microbiota composition in mice with antibiotic-associated diarrhea. cutaneous autoimmunity Forty-eight Balb/c mice were randomly allocated into six groups: control (Con), AAD, inulin (Inu), Cistanche deserticola (RCR), Cistanche deserticola polysaccharide (RCRDT), and Echinacoside (Ech), with eight mice in each group. Intragastric administration of lincomycin hydrochloride (3 g/kg) for seven days established the diarrhea model in mice. This was followed by intragastric treatments of INU (5 g/kg), RCR (5 g/kg), RCRDT (200 mg/kg), and ECH (60 mg/kg), once daily for seven days. The control and AAD groups received normal saline. The study investigated the effects of Cistanche deserticola, its polysaccharide, and Echinacea glycoside on antibiotic-driven intestinal flora disruption in mice using general signs of mice, colon HE staining, and 16S rDNA high-throughput sequencing. Weight loss, prominent diarrhea, inflammatory colon tissue changes, and a reduction in intestinal flora diversity (P<0.005) were observed in AAD group mice, in contrast to the control group, highlighting the model's success. The AAD group showed poorer outcomes for weight and diarrhea compared to the notable improvement observed in the INU, RCR, RCRDT, and ECH groups; the colon pathology in the ECH group recovered to a normal state. The RCR, RCRDT, and ECH groups exhibited a statistically significant (P<0.005) reduction in intestinal Firmicutes, compared to the AAD group, along with an increase in Blautia and Lachnoclostridium, and a decrease in Clostridium sensu stricto 1. Following ECH intervention, intestinal microflora abundance and diversity normalized, and the intestinal microflora structure exhibited a proper adjustment, evidenced by increases in Bacteroides, Flavonifractor, Agathobacter, Lachnoclostridium, and Prevotella-9 (P001). Conclusively, the restorative actions of Cistanche deserticola, specifically its components cistanche deserticola polysaccharide and echinacoside, are effective in regulating the imbalance in intestinal flora induced by antibiotics, resulting in improved AAD symptoms, notably the impact of echinacoside.
The study's objective was to explore the influence of polystyrene nanoplastics (PS-NPs) exposure during pregnancy on the development and neurotoxicity of fetal rats. For the methods, a random assignment procedure was used to divide twenty-seven pregnant Sprague-Dawley rats into nine groups, with three animals in each. A PS-NPs experimental group, receiving 05, 25, 10, and 50 mg/kg of PS-NPs suspension with distinct particle sizes (25 and 50 nm) via gavage, was contrasted with a control group receiving ultrapure water via the same gavage method. Gavage is administered between the first and the eighteenth days of pregnancy. Placental structural alterations were observed; a comparison of male and female fetuses and further classification of live, dead, and resorbed fetuses was conducted; further, the body weight, body length, placental weight, and organ coefficients (kidney, liver, brain, intestine) of fetal rats were measured, following which the prefrontal cortex, hippocampus, and striatum of the fetal rats were subject to tests for relevant biochemical markers. The PS-NPs exposed group's placentas demonstrated structural harm, progressively more pronounced with elevated doses, in contrast to the control group's healthy state. There was a marked increase in trophoblast area ratio (P<0.05), coupled with a significant reduction in labyrinth area ratio (P<0.05). Maternal polystyrene nanoparticle exposure during pregnancy may impact fetal rat growth and development, potentially by compromising the placental barrier and inducing neurotoxicity in the fetus, resulting in oxidative stress and inflammatory responses throughout the brain. Furthermore, smaller polystyrene nanoparticle sizes and higher doses appear to correlate with more pronounced neurotoxic effects on the developing offspring.
