Chow group participants consumed AIN-93G feed, contrasting with the HMD and HMD+HRW groups, who were given AIN-93G plus 2% methionine to create an HHcy model. The HMD+HRW group consumed hydrogen-rich water (3 ml per animal, twice a day, containing 0.8 mmol/L hydrogen), while body weight measurements were taken. After six weeks of feeding, the liver and plasma samples underwent processing and were gathered. Measurements of plasma homocysteine (Hcy) and lipid levels, along with observations of the liver's histological morphology, were conducted for each group. Enzyme activity and mRNA transcript levels related to Hcy metabolism were evaluated in liver samples. The Hcy level in the blood of HMD rats showed a statistically significant increase (P<0.005) when compared to the control group, the CHOW rats. Examination of rat liver tissue sections revealed an increase in liver size, tissue damage, and fatty deposition; the HMD+HRW group showed a decrease in blood homocysteine levels, a reduction in liver damage, and an increase in the activity and mRNA expression of key homocysteine-metabolizing enzymes in the liver, with statistically significant differences (P<0.005) compared to the HMD group. Hydrogen administration demonstrably enhances liver function in hyperhomocysteinemic rats fed a high-methionine diet, possibly by optimizing three critical metabolic pathways for homocysteine detoxification, thus improving liver metabolic function and alleviating symptoms of non-alcoholic fatty liver disease.
Our study aimed to investigate the intervention efficacy of curcumin (Curc) on chronic alcohol-induced liver damage in a murine model. Thirty Balb/c mice were randomly assigned to five groups for this experiment: a normal control group, a model group, and three curcumin-treated groups (5, 10, and 15 mg/kg), with each group containing six mice to observe the effects of varying curcumin doses. Preparation of the chronic alcohol addiction liver injury model involved the use of a 20% alcoholic liquor. Two milliliters of normal saline were administered daily to the mice in the control group. For 35 days, mice in the control group were given 5 ml/kg of 20% liquor each day, while Curc-treated mice received 5, 10, or 15 mg/kg of Curc diluted in 2 ml of saline daily. The health status of the mice and the weight of the liver were both recorded. Serum ALT, AST, ALP, liver TG, TC, HDL-C, LDL-C, MDA, SOD, GSH-Px, and NO were examined to assess their respective concentrations. Pathological changes were apparent in hematoxylin and eosin-stained liver tissue specimens. The liver mass and serum markers (ALT, AST, ALP, MDA, NO, TC, TG, HDL-C, LDL-C) were significantly increased in the model group compared to the control group (P<0.005, P<0.001). Conversely, the activities of SOD and GSH-Px were significantly decreased (P<0.005, P<0.001). Histological analysis showed liver cell vacuolation, inflammatory cell infiltration, and a substantial increase in NF-κB and MAPK protein expression levels in the liver (P<0.001). The Curc group demonstrated a substantial decline in ALT, AST, ALP, MDA, NO, TC, TG, HDL-C, and LDL-C concentrations, and a significant increase in SOD and GSH-Px activities relative to the model group (P<0.005, P<0.001). HBV hepatitis B virus Curcumin demonstrates an ability to lessen liver tissue damage through the modulation of NF-κB/MAPK signaling pathway activity.
The purpose of this investigation is to determine the effects of Mijian Daotong Bowel Suppository (MJDs) on a diphenoxylate-induced constipation model in male rats, and to identify the mechanisms of its action. Sixty male SD rats were randomly distributed into four groups, blank, model, positive, and MJDs, for the purpose of establishing methods. Employing compound diphenoxylate gavage, a constipation model was developed. The saline enema was administered to the rats in the control and model groups, while the rats in the positive and MJDs groups received a Kaisailu and honey decoction laxative suppository enema, once daily for ten days. The rats' body weight, fecal water content, gastric emptying rate (GER), and carbon ink propulsion rate (CIPR) were all examined and recorded during the modeling and administration procedures. The pathological alterations in colon tissue of constipated rats, induced by MJDs, were investigated using hematoxylin-eosin (HE) staining. Using an ELISA kit, the study explored the impact of MJDs on the 5-hydroxytryptamine (5-HT) content in the colon tissues of rats suffering from constipation. Analysis of colon tissue samples, utilizing immunohistochemical techniques, revealed the effects of MJDs on aquaporin 3 (AQP3) and aquaporin 4 (AQP4) expression in rats exhibiting constipation. nano bioactive glass A marked increase in fecal water content and colon 5-HT content was observed in the positive group compared to the model group; concurrently, a significant reduction in colon AQP3 and AQP4 expression was also noted. Among the MJDs, significant increases were seen in body weight, fecal water content, and colon 5-HT content, contrasting with a significant decrease in the expression of AQP3 and AQP4 (P<0.005 and P<0.001, respectively). The fecal water content of the MJDs group was considerably lower than that of the positive group, and a significant decrease was also found in the expression of AQP3 and AQP4 within the colon of the MJDs group (P<0.005 and P<0.001, respectively). No statistically significant variation in gastric emptying rate was evident between the experimental and control groups. MJDs demonstrate positive therapeutic outcomes in managing constipation, potentially through increasing 5-HT levels within the colon and reducing AQP3 and AQP4 expression therein.
The present study investigates the influence of Cistanche deserticola, comprised of Cistanche deserticola polysaccharide and Echinacoside, on the intestinal microflora of mice suffering from antibiotic-associated diarrhea. MDV3100 Randomly divided into six groups, forty-eight Balb/c mice comprised control (Con), AAD, inulin (Inu), Cistanche deserticola (RCR), Cistanche deserticola polysaccharide (RCRDT), and Echinacoside (Ech) groups, each group consisting of eight mice. A lincomycin hydrochloride (3 g/kg) intragastric administration for seven days established a murine diarrhea model. Thereafter, intragastric administration of INU (5 g/kg), RCR (5 g/kg), RCRDT (200 mg/kg), and ECH (60 mg/kg), 0.2 ml daily for seven days, was conducted on the experimental groups. The control and AAD groups received equivalent volumes of normal saline. Using general mouse characteristics, colon HE staining, and 16S rDNA high-throughput sequencing, the influence of Cistanche deserticola, its polysaccharide, and Echinacea glycoside on antibiotic-induced intestinal microflora disruption in mice was examined. Compared to the control group, AAD group mice experienced weight loss, presented clear symptoms of diarrhea, displayed inflammatory changes in their colonic tissue, and showed a decrease in intestinal microbial diversity (P<0.005), confirming the model's success. The INU, RCR, RCRDT, and ECH groups experienced a substantial improvement in weight and diarrhea compared to the AAD group; this was accompanied by a restoration of normal colon pathology in the ECH group. When compared with the AAD group, the RCR, RCRDT, and ECH groups presented a significant decline in intestinal Firmicutes, a rise in Blautia and Lachnoclostridium, and a reduction in Clostridium sensu stricto 1 (P<0.005). In the ECH group, the intestinal microflora returned to its usual abundance and diversity, and its structure was successfully readjusted, resulting in increased numbers of Bacteroides, Flavonifractor, Agathobacter, Lachnoclostridium, and Prevotella-9 (P001). Finally, the research highlights that Cistanche deserticola and its key components, cistanche deserticola polysaccharide and echinacoside, effectively manage the dysbiosis of the intestinal flora resulting from antibiotic use, improving AAD symptoms, primarily via echinacoside's action.
A study aimed at examining the impact of gestational exposure to polystyrene nanoplastics (PS-NPs) on the growth and neurotoxicological consequences in fetal rats. In the methods, twenty-seven pregnant Sprague-Dawley rats were randomly divided into nine groups, with three rats designated per group. The experimental PS-NPs group received varying dosages (05, 25, 10, and 50 mg/kg) of PS-NPs suspension with 25 and 50 nm particle sizes delivered via gavage. The control group, conversely, received ultrapure water administered via gavage. Pregnancy days one through eighteen mark the window for gavage. A study of placental morphological changes was carried out; differences in the number of male and female fetuses, along with live, dead, and resorbed fetuses, were examined, accompanied by analysis of body weight, body length, placental weight, and organ coefficients (kidney, liver, brain, intestine) of fetal rats; the prefrontal cortex, hippocampus, and striatum of the fetal rats were used to determine associated biochemical markers. A dose-dependent rise in structural damage was observed in the placentas of the PS-NPs exposed group, in contrast to the control group's intact placentas. A noteworthy elevation in trophoblast area ratio (P<0.05) was seen, contrasted by a substantial decrease (P<0.05) in labyrinth area ratio. Maternal polystyrene nanoplastic exposure during pregnancy potentially affects fetal rat growth and development by harming the placental barrier and inducing neurotoxicity in the fetus. This includes oxidative stress and inflammatory responses in multiple brain regions. Furthermore, the smaller sizes and higher concentrations of polystyrene nanoplastic are directly associated with more significant neurotoxic effects on offspring.
