Effect of sainfoin (Onobrychis viciifolia Scop.) seed-based diet on rats: A comprehensive evaluation of hemogram, biochemistry, and histopathology.

Sainfoin species (Onobrychis spp.) have been employed for centuries as an essential forage for ruminant animals, both for grazing and as hay. The seeds produced by sainfoin have also been investigated as an animal feed source and were indicated to be a particularly protein-rich supplement for monogastric animals. This study explores the effects of two sainfoin seed inclusion rates in rat diets compared to a control diet, focusing on blood biochemical parameters and a comprehensive histopathological evaluation of multiple organ systems. Thus, we provide a novel contribution to the body of evidence investigating sainfoin seeds as a protein supplement in monogastric animal diets. In this 21-day experiment, seven rats each were assigned to the control group, a 5% sainfoin seed group, and a 10% sainfoin seed group. The control group received standard feed and water; the second group received feed with 5% sainfoin seeds; and the third group received feed with 10% sainfoin seeds. At the experiment's end, necropsies and evaluations were conducted. Histopathological exams revealed normal organ structures in all 21 samples, regardless of the group. Blood analysis showed statistically significant decreases in creatine, ALT, P, Ca, and Mg levels in the sainfoin seed groups compared to the control group, with most values nearing reference levels, suggesting potential benefits. Notably, no adverse effects were observed when sainfoin seeds were included at 5% and 10% in the rat feed. These findings contribute to a growing body of research investigating the inclusion of sainfoin seeds in monogastric animal diets, which is a foundational component of assessing sainfoin's potential as a novel pulse crop for human consumption.

Probiotic bacteria protect against indomethacin-induced gastric ulcers through modulation of oxidative stress, inflammation, and apoptosis.

BACKGROUND: Indomethacin is an anti-inflammatory drug that causes ulcers on the gastric mucosa due to its use. Probiotic bacteria are live microorganisms, and it has been stated by various studies that these bacteria have antioxidant and anti-inflammatory effects. In this study, we investigated the possible protective effect of various types of probiotic bacteria (Lactobacillus rhamnosus, Lactobacillus fermentum, and Lactobacillus brevis) against acute gastric mucosal damage caused by indomethacin. METHODS: Control group - Physiological saline was administered daily for 10 days. Indo group-Physiological saline was administered daily for 10 days. Ranitidine + Indo group 5 mg/kg ranitidine dose was administered daily for 5 days. On day 11, a single dose of 100 mg/kg of indomethacin was given to the same group. Probiotic + Indo group 1 ml/kg of oral probiotic bacteria was administered daily for 10 days. On day 11, a single 100 mg/kg dose of indomethacin was given. After the application, the rats were anesthetized with ketamine xylazine, killed under appropriate conditions, the abdominal cavity was opened and the stomach tissues were removed. The obtained gastric tissues were used in the biochemical and histopathological analyses discussed below. All data were statistically evaluated by one-way ANOVA using SPSS 20.00, followed by Duncan Post hoc test. The data were expressed as mean ± SD. P < 0.05 was considered statistically significant. RESULTS: As a result, the administration of indomethacin caused gastric damage, stimulating oxidative stress, inflammation, and apoptosis. We found that the use of probiotic bacteria reduces oxidative stress (TOC), increases the activity of antioxidant enzymes (TAC), suppresses inflammation (IL-6 and Tnf-α), and inhibits apoptosis (Bax and Bcl-2) (P < 0.05). CONCLUSION: Probiotic treatment can mitigate gastric damage and apoptosis caused by indomethacin-induced gastric damage in rats. Probiotic also enhances the restoration of biochemical oxidative enzymes as it has anti-inflammatory, antioxidant, and antiapoptotic properties.

Hydrogen-rich water supplementation improves metabolic profile during peripartum period in Gurcu goats and enhances the health and survival of kids.

In this study, the effect of intaking hydrogen-rich water (HRW) on the metabolic profile of Gurcu goats during the peripartum period and the survival/growth performance of kids were evaluated. Twenty-three pregnant goats were divided into two groups 21-23 days before the due date. Group 1 (G1, n = 10) was given HRW from day 21 before delivery until day 21 after delivery. Group 2 (G2, n = 13) served as the control. Blood samples were weekly taken from 21 days before delivery until 21 days after delivery. Hydrogen-rich water increased serum glucose concentration on the delivery day more than in G2 (P = 0.016). Hydrogen-rich water decreased serum total cholesterol (P = 0.02) and creatinine (P = 0.05) concentration at delivery. Group effect and time effect were significant in triglyceride (P < 0.001, P = 0.001, respectively) and albumin (P < 0.001, P = 0.002, respectively) concentration. Aspartate transaminase decreased towards the delivery day in G1 (P < 0.05). Serum non-esterified fatty acids concentration was lower in G1 than in G2, but there was no significant differences (P > 0.05). Beta-hydroxybutyric acid concentration an increased in both groups during the prepartum period, although there was no significance (P > 0.05). Hydrogen-rich water did not affect the birth weight and growth performance of the kids (P > 0.05), but it increased their survival rates and overall health, although there was no significance (P > 0.05). In conclusion, HRW may have an impact on the metabolic profiles during the peripartum period and have a positive effect on lipid profiles. Additionally, intaking HRW to goats during the peripartum period may improve the health and survival of kids and reduce their mortality.

Anti-inflammatory, antioxidant, antiangiogenic, and therapeutic efficacy of neroli oil in rats with endometriotic lesions.

INTRODUCTION: Endometriosis is a serious health problem among women of reproductive age, with pelvic pain and infertility. Given the limited success of current treatments, this study explores Neroli oil (N.O.) effects on inflammation, oxidation, angiogenesis, and tissue remodeling implicated in endometriosis. MATERIALS AND METHODS: Albino Wistar female rats were used to simulate an endometriosis model. Groups were established for comparison: a control, an endometriosis model, a N.O.-treated group, and a N.O.-treated group postendometriosis induction. The study focused on Tumor necrosis factor-alpha (TNF-α), Interleukin 6, Interleukin 8, vascular endothelial growth factor (VEGF), myeloperoxidase, Matrix metalloproteinase-1 (MMP-1), nitric oxide, superoxide dismutase, catalase, and anti-mullerian hormone values, as well as histopathological evaluations of endometriotic foci. RESULTS: AMH values showed a significant increase in the endometriosis group treated with N.O. compared with the endometriosis group (p < 0,01).A statistically significant decrease was found in MMP-1 level in the endometriosis group that underwent N.O. (p < 0.001). Increased CAT (p < 0.0001) and decrease in nitric oxide (p < 0.01) are found in N.O.-treated endometriosis group. TNF-α levels in the endometriosis group showed a statistically significant increase in the endometriosis group when compared with the control and sham group (p < 0.001, p < 0.01 respectively). In our study, a statistically significant increase was observed in VEGF levels (p < 0.001) in endometriosis group and significant decrease in the N.O. administered endometriosis model group. Groups treated with N.O. showed decreased inflammation and congestion scores. Histopathological assessments demonstrated reduced inflammation and tissue remodeling signs in endometriotic foci. CONCLUSION: This study highlights the potential of N.O. in the treatment of endometriosis, owing to its anti-inflammatory, antioxidant, and antiangiogenic properties that can disrupt chronic processes. Our findings lend support to utilization of herbal remedies for the management of endometriosis, thereby emphasizing the necessity for additional comprehensive investigations in the future.

Investigation of antimicrobial and antioxidant activities of Chenopodium album extracts and their effects on gentamicin nephrotoxicity in rats.

This study aims to examine the antimicrobial and antioxidant activities of the aerial parts of Chenopodium album extracts (CAE) prepared with different solvents, and how C. album ethanol extract protects them against gentamicin-induced nephrotoxicity. Extracts of C. album aerial parts were obtained from ethanol, water, methanol, chloroform, and hexane solvents. Thirty-two male Wistar albino rats were used and gentamycin-induced nephrotoxicity was utilized as a model. The water extract of C. album exhibited no antimicrobial effect, whereas the methanol one created the highest zone diameter on Bacillus cereus (26 mm). The methanol extract displayed the highest activity in DPPH and ABTS. The ethanol extract yielded the highest reducing power in the CUPRAC. The water extract had the highest reducing power in the FRAP. Concerning gentamicin-induced renal damage, creatinine and urea levels in the blood were statistically higher in the gentamicin-C. album group compared to the other groups (p < .05). Urea and creatinine levels of the gentamicin-C. album group dropped significantly, indicating that the C. album was effective against renal damage. The sections from kidney tissues in the gentamicin + C. album group mostly exhibited mild glomerular congestion. Hyaline cast, cytoplasmic vacuolization, necrosis, and apoptosis were not observed. Thanks to C. album treatment, the gentamicin + C. album suffered less histopathological damage than the gentamicin group did. The results of the present study suggest that CAE can be used as a supportive treatment in people undergoing treatment for nephrotoxicity.

The effect of hydrogen-rich water on letrozole-induced polycystic ovary syndrome in rats.

RESEARCH QUESTION: What is the effect of hydrogen-rich water on rats with polycystic ovary syndrome (PCOS)? DESIGN: Female rats were divided into four groups, each consisting of eight animals. The control group received a carboxymethyl cellulose (CMC) solution, the molecular hydrogen (H2) group was given hydrogen-rich water and a CMC solution, the PCOS group was administered letrozole dissolved in a CMC solution and the PCOS + H2 group was given hydrogen-rich water and letrozole dissolved in a CMC solution. Blood and tissue samples were then collected, and biochemical and histopathological analyses were conducted on the samples. RESULTS: The histopathological analysis showed a reduction in the number of cysts in the PCOS + H2 group compared with the PCOS group (P < 0.0001). Additionally, the malondialdehyde, cortisol and testosterone data revealed a significant decrease in the PCOS + H2 group compared with the PCOS group (P = 0.0458, P = 0.0003, P = 0.0041, respectively). The glutathione also showed a statistically significant increase in the PCOS + H2 group compared with the PCOS group (P = 0.0012). CONCLUSION: The study findings demonstrate that hydrogen-rich water reduces the number of cysts and oxidative damage in rats with PCOS.

Protective Effect of Hydrogen-Rich Saline on Spinal Cord Damage in Rats.

The anti-inflammatory and anti-apoptotic effects of molecular hydrogen, delivered as hydrogen-rich saline (HRS), on spinal cord injury was investigated. Four-month-old male Sprague Dawley rats (n = 24) were classified into four groups: (1) control-laminectomy only at T7-T10; (2) spinal injury-dura left intact, Tator and Rivlin clip compression model applied to the spinal cord for 1 min, no treatment given; (3) HRS group-applied intraperitoneally (i.p.) for seven days; and (4) spinal injury-HRS administered i.p. for seven days after laminectomy at T7-T10 level, leaving the dura intact and applying the Tator and Rivlin clip compression model to the spinal cord for 1 min. Levels of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were measured in blood taken at day seven from all groups, and hematoxylin-eosin (H & E) and terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) were used to stain the tissue samples. IL-6 and TNF-α levels were significantly lower in the group treated with HRS following the spinal cord injury compared to the group whose spinal cord was damaged. A decrease in apoptosis was also observed. The anti-inflammatory and anti-apoptotic effect of IL-6 may be a clinically useful adjuvant therapy after spinal cord injury.

Effects of Ozone Therapy on Chronic Arsenic Poisoning in Rats.

Arsenic (As) is a toxic metalloid that affects many organs through drinking water. This study aims to examine the efficacy of ozone therapy on chronic arsenic toxicity. Twenty-four male Wistar albino rats were housed in individual cages and grouped as control, As, O3, and As + O3. As was applied by adding 5 mg/kg/day in drinking water for 60 days. Ozone therapy was applied at 0.5 mg/kg/day (i.p.) O3 in the last 5 days of the experimental period. Tissues were harvested and analyzed for histopathological injury and apoptotic markers. There was no significant difference between the As + O3 and O3 groups (p = 0.186 and p = 0.599) for light microscopic criteria: inflammatory cell infiltration and hydropic degeneration in liver tissue.In TUNEL assessments, similar outcomes were obtained in the control and As + O3 groups. A statistically significant increase was observed in p53 and Caspase 3 (Casp-3) expression levels in the As group compared to the O3 and As + O3 groups. There was no significant difference between the As + O3 and O3 groups on peritubular hemorrhage and desquamation parameters in kidneys (p = 0.147 and p = 0.094). The KIM-1 expression level was significantly increased in the As group compared to the As + O3 group (p = 0.01), and the Casp-3 expression level was not significantly changed in the O3 group compared to the As + O3 group (p = 0.59). In conclusion, it is determined that ozone therapy has ameliorative effects on the microscopic injury of liver and kidney tissues. In addition to microscopic improvement, KIM-1 gene expression levels were ameliorated in the kidneys. The apoptotic cell counts and the Casp-3 and p53 gene expression levels were decreased by O3 administration. Thus, ozone therapy can be a treatment choice for As toxicity.

Effects of hyperbaric oxygen treatment on liver and kidney tissue in chronic arsenic toxicity.

Arsenic (As) is a toxic substance that damages the human body through exposure to drinking water. This exposure damages many organs and tissues in the body, especially the liver and kidneys. Hyperbaric oxygen (HBO2) therapy is a treatment method that acts by reducing oxidative stress parameters in tissues with high-pressure oxygen. Based on this, our study aimed to investigate the effectiveness of HBO2 on liver and kidney tissues with chronic arsenic toxicity. In the study 24 male Wistar albino rats (220-300 g, two to three months old) were equally divided into four groups: Control; As; HBO2; and As+HBO2. All animals were housed in individual cages. The toxicity model was created by adding arsenic to drinking water at a dose of 5 mg/kg/day for 60 days. HBO2 was applied 2 ATA pressure for 90 minutes a day for five days. At the end of the study, liver and kidney tissues were taken and stored for analysis. In liver tissue, histopathological showed that arsenic reduced inflammatory cell infiltration, sinusoidal congestion, and hydropic degeneration, while HBO2 increased these measures. Similar results were found by TUNEL method. In kidney tissue, both histopathologic and TUNEL method examinations found similar results with the liver: The As group was more damaged than the As+HBO2 group.
