Effects of hesperidin on the histological structure, oxidative stress, and apoptosis in the liver and kidney induced by NiCl 2. Front Vet Sci 2024; 11:1424711. [PMID: 38983771 PMCID: PMC11231102 DOI: 10.3389/fvets.2024.1424711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2024] [Accepted: 06/14/2024] [Indexed: 07/11/2024] Open
Abstract
The aim of this study was to investigate the effect of hesperidin on the liver and kidney dysfunctions induced by nickel. The mice were divided into six groups: nickel treatment with 80 mg/kg, 160 mg/kg, 320 mg/kg hesperidin groups, 0.5% CMC-Na group, nickel group, and blank control group. Histopathological techniques, biochemistry, immunohistochemistry, and the TUNEL method were used to study the changes in structure, functions, oxidative injuries, and apoptosis of the liver and kidney. The results showed that hesperidin could alleviate the weight loss and histological injuries of the liver and kidney induced by nickel, and increase the levels of lactate dehydrogenase (LDH), alanine aminotransferase (GPT), glutamic oxaloacetic transaminase (GOT) in liver and blood urea nitrogen (BUN), creatinine (Cr) and N-acetylglucosidase (NAG) in kidney. In addition, hesperidin could increase the activities of superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and glutathione peroxidase (GSH-Px) in the liver and kidney, decrease the content of malondialdehyde (MDA) and inhibit cell apoptosis. It is suggested that hesperidin could help inhibit the toxic effect of nickel on the liver and kidney.

Abstract
OBJECTIVE Diosmin, a natural flavone glycoside, possesses antioxidant activity and has been used to alleviate ischemia/reperfusion (I/R) injury. The aim of this study was to clarify whether the administration of diosmin has a protective effect against I/R injury induced using the high intraocular pressure (IOP) model in rat retina, and to determine the possible antioxidant mechanisms involved. METHODS Retinal I/R injury was induced in the rats by elevating the IOP to 110 mmHg for 60 min. Diosmin (100 mg/kg) or vehicle solution was administered intragastrically 30 min before the onset of ischemia and then daily after I/R injury until the animals were sacrificed. The levels of malondialdehyde (MDA) and the activities of total-superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) in the retinal tissues were determined 24 h after I/R injury. At 7 days post-I/R injury, electroretinograms (ERGs) were recorded, and the density of surviving retinal ganglion cells (RGCs) was estimated by counting retrograde tracer-labeled cells in whole-mounted retinas. Retinal histological changes were also examined and quantified using light microscopy. RESULTS Diosmin significantly decreased the MDA levels and increased the activities of T-SOD, GSH-Px, and CAT in the retina of rats compared with the ischemia group (P<0.05), and suppressed the I/R-induced reduction in the a- and b-wave amplitudes of the ERG (P<0.05). The thickness of the entire retina, inner nuclear layer, inner plexiform layer, and outer retinal layer and the number of cells in the ganglion cell layer were significantly less after I/R injury (P<0.05), and diosmin remarkably ameliorated these changes on retinal morphology. Diosmin also attenuated the I/R-induced loss of RGCs of the rat retina (P<0.05). CONCLUSION Diosmin protected the retina from I/R injury, possibly via a mechanism involving the regulation of oxidative parameters.

Abstract
Most chronic wounds can be classified into three major types: pressure ulcers, venous ulcers, and diabetic ulcers. The authors propose a unifying hypothesis of chronic wound pathogenesis based on four main causative factors: local tissue hypoxia, bacterial colonization of the wound, repetitive ischemia-reperfusion injury, and an altered cellular and systemic stress response in the aged patient. Traditional strategies for the treatment of chronic wounds have shown limited success. The authors explore potential treatment regimens specifically aimed at each individual determinant of chronic wound pathogenesis. Furthermore, they explore a combined therapeutic approach that collectively targets all the components of chronic wound pathology. These innovative ideas and therapies could be of substantial interest for clinicians and researchers, while further offering significant benefit to patients with chronic wounds.

Abstract
Purified micronized flavonoid fraction, comprising 90% diosmin and 10% hesperidin, is basically used as a phelebotonic and vasculoprotector agent. It also has anti-inflammatory and anti-edematous actions. This study was designed to evaluate the efficacy of micronized flavonoid fraction in clean and infectious wounds. Sixty Guinea pigs were separated into 2 main groups and 6 subgroups. The first three groups had clean wounds and the other three groups had infected wounds contaminated with S. aureus. Then these main groups were separated into 3 subgroups. The first subgroups was treated with 60 mg/kg/day micronized flavonoid fraction per oral, the second ones was treated with topical 60 mg/kg/day micronized flavonoid fraction, and the third ones had no treatment. Infected wounds were obtained by contamining the wounds with S. aureus. There were no significant differences in wound healing between the groups that have clean wounds (p > 0.05). In the groups with infected wounds, orally and topically treated guina pigs had accelerated wound healing compared to the untreated control group (p < 0.05), confirmed with surface area measurements and histopathological evaluation. Healing showed no difference between the groups treated orally and topically. This study showed that oral or topical administration of micronized flavonoid fraction in the infected wounds is beneficial, while it has no significant effect in clean wounds. </hea

Abstract
The objective of this study was to investigate the effects of the purified, micronized, flavonoid fraction Daflon 500 mg (S 5682, 90% diosmin and 10% hesperidin) on tissue damage and leukocyte emigration in striated skin muscle after ischemia-reperfusion, as assessed by histomorphometric analysis. The experimental model used was the transparent dorsal skin fold chamber in the awake Syrian golden hamster. Sixty-four animals were randomly allotted to two treatment groups and time points of investigation. Animals were fed with 30 mg kg(-1) body weight Daflon 500 mg (n = 32) or its vehicle, 5% Arabic gum solution (n = 32), as control 8 hours before ischemia. Before induction of a tourniquet ischemia of 4 hours' duration and at 0.5, 2, and 24 hours of reperfusion, tissue sections were preserved for light and electron microscopic analysis (n = seven or eight animals per time point). The number of intravascular and extravascular leukocytes was determined by light microscopic analysis of esterase-positive leukocytes. For quantitative analysis of ischemia-induced endothelial cell damage, the endothelial thickness of capillaries was calculated by a computer-assisted imaging system, whereas the ischemic tissue damage was assessed by means of a score system (grade 0-3) by an independent investigator. The number of emigrated leukocytes was significantly reduced in Daflon 500 mg-treated animals compared with numbers found in control animals. The histomorphologic muscle fiber damage increased after reperfusion in both groups but was significantly reduced in the Daflon 500 mg-treated animals 2 and 24 hours after reperfusion. These results suggest that the emigration of leukocytes plays an important role in the development of postischemic reperfusion injury of striated skin muscle.
