INTRODUCTION

The exponential rise in the use of heavy metals in numerous industries and goods has resulted in a substantial increase in human exposure to them during the past 50 years (Perrone et al., 2023). Mercury is the most prevalent heavy metal contaminant in the environment. Mercury exists in three different forms: elemental (or metallic), inorganic, and organic (Nandiyanto et al., 2023). Due to its persistence, toxicity, bioaccumulation, and consumption of contaminated fish (such as swordfish, tuna, or shark), mercury provides a health concern to humans and other organisms despite its low prevalence in nature (Perrone et al., 2023). Mercury is frequently employed in both industrial and agricultural operations (Palathoti et al., 2022). It is a very persistent substance in the environment, and its gaseous and liquid forms are carried by air and water (Lin et al., 2020). The human body’s numerous organs can be affected by inhaling gaseous mercury; after entering the bloodstream and interacting with red blood cells, it eventually builds up in the kidneys most of the deposited mercury in the body accumulated in the proximal tubule, also, the brain and nervous system is potentially affected by mercury intoxication (Gupta et al., 2018). Mercury found in water and soil can be ingested by plants, animals, and humans through the food chain after being absorbed by them (Ge et al., 2022). Mercury and its products contained a wide range of contaminants that cause destruction effects on aquatic environment. This is elemental mercury, an organic substance such as ethyl, Methylmercury and inorganics (Alrudainy, 2014; Mustafa and Al-Rudainy, 2021). Due to the susceptibility of renal tissue to mercury poisoning resulted from its high affinity to bind into tubular tissues, the kidney shows insufficiency in its function faster than other tissues (Gao et al., 2022) such as skin (Kuehn, 2020), When compared to the brain and liver (Chan, 2011). The kidneys store the most mercury and renal toxicity has a long history of research in the literature (Gao et al., 2022). A transcriptional factor known as nuclear factor B (NF-kB) that protects cells from apoptotic stimuli and encourages cell survival (Alharbi et al., 2022). One of the most potent thiol-binding compounds, mercury ion Hg++, inhibits DNA binding and NF-kB activation in kidney epithelial cells at low molar M concentrations, causing apoptosis (Kumar et al., 2022). When kidney function and immunologic markers in chloralkaline employees (The chlor-alkali process is an industrial process for producing caustic soda and chlorine by electrolysis of brine) with long-term low mercury vapor exposure were evaluated, they showed that the exposure had an impact on the kidney’s proximal tubule cells (Makena et al., 2022). (P<0.05) increase in HD group in comparison to the control group only Figure 2C.

The best measure for predicting death in people with non-chronic kidney disease illnesses is an elevated uric acid value. In order to provide these patients with a thorough examination and treatment that will enhance their prognosis, uric acid rate can be a valuable guidance.

The blood urea nitrogen and blood creatinine ratio, also known as the urea creatinine ratio (UCR), is a measured laboratory value that aids in the differential diagnosis of kidney disease and affect the egg layer chickens (Ma et al., 2018). In turn, this leads to an unbalanced rise in blood urea in comparison to serum creatinine and an elevated UCR (Ma et al., 2018). Resveratrol, a polyphenolic substance called RES (3, 5, 4′-trihyroxystilbene) was first discovered in the roots of Veratrum grandiflorum and then in the roots of Polygonum cuspidatum. It has a stilbene structure and comes in both cis and trans isomeric forms (Domi et al., 2022). Red grapes, cranberries, blueberries, peanuts, soy, and wine are the top RES dietary sources. especially red grapes the positive effects of RES are well documented; they include anti-inflammatory, antioxidant, antiviral, anti-aging, and life-prolonging activities. It also inhibits cell regulation and the production of pro-inflammatory cytokines, which has immunomodulating characteristics (Domi et al., 2022). Resveratrol seems to work Through multiple cells signaling pathways, including induction of cell cycle arrest; stimulation of apoptosis and differentiation, suppression of inflammation and angiogenesis, Adhesions, Infiltration, and metastasis (Khayoon and Al-Rekabi, 2021). This study aimed to evaluate the physiological tolerance of renal system, immune system and redox system against the mercuric chloride toxicity in rats.

MATERIALS AND METHODS

Experimental animals

Eight to ten-week-old female Sprague Dawley adult rats weighing 170-220 g the rats were acclimated for two weeks. Food and drink were ad libitum.

Institutional animal care and use committee statement

Before performing any experiment, the experimental design and protocols used in current study were examined and approved in accordance with the animal welfare ethical measurements by the Scientific Committee of the Department of Physiology, Biochemistry and Pharmacology, College of Veterinary Medicine, University of Baghdad and the Ethics Committee of the College of Veterinary Medicine, University of Baghdad, Baghdad – Iraq (IACUC#: P.G.-1293).

Animal grouping

Forty-five rats divided into 5 groups (n=9); each group treated differently as following:

Group C: Served as control group. Group R: The resveratrol group was given orally at a dose of 100 mg/Kg (Alghetaa et al., 2018, 2021, 2023). Group HD: Received mercuric chloride (HgCl2) with i.p. injection at dose 1 mg/kg, (Said et al., 2021; Shalan 2022). Group RH: Received mercuric chloride and Resveratrol (HgCl2+ RES). Group D: Received DMSO orally.

Parameters

A- Kidney function tests: done by Urea, Uric acid, Creatinine (Mohammed, 2010)

B- Evaluate the protein profile: Albumin, Globulin, Total protein, Total bilirubin (Mahendra et al., 2023).

C- Evaluate the redox system balance: Total antioxidant capacity (Idrees et al., 2023).

D- Evaluation of peritoneal immunological response (infiltrating cell counts) (Alghetaa et al., 2018)

Preparation of HGCL2

HgCl2 solution is made in the following way. 100 mg of mercury chloride was dissolved in 100 ml of distilled water and the dose was 1µg.1µl-1/1g of body weight (Said et al., 2021; Sheta et al., 2022).

Preparation of RES

Two capsules of Resveratrol (Now, USA) were dissolved in 1 ml DMSO, followed by adding 9.0 ml distilled water. The dosage was 100 mg per kilogram of body weight (Wei et al., 2021).

Blood serum samples

At the endpoint of the experiments, blood samples were taken under general anesthesia with an overdose of 4mg/kg of xylazine and 150mg/kg of ketamine mixture (Sotoudeh and Namavar, 2022) from retro-orbital veins, then the blood was left to clot for few minutes at room temperature. The following step was estimation of biomarkers of kidney function in the serum.

Evaluation of peritoneal immunological status

This was accomplished by euthanizing the animals after being generally anesthetized with intramuscular overdose of xylazine and ketamine (Sotoudeh and Namavar, 2022), then once the animal been unconscious, toe pinch reflex was tested and when it resulted negative response, the abdominal skin was immediately opened up and separated from the peritoneal sac. Then all experimental animals were injected with 10ml normal saline into the peritoneum, then emptying the fluid into a petri dish, afterward, the peritoneal exudates were collected in centrifuge tube to be spanned down at 3700 rpm for 7 minutes. The cells pellets were then resuspended in 500µl of normal saline and then stained with trypan blue dye and counted by light microscope by using Neubauer hematocytometer chamber with a staining rate of sample to dye as 1:10 (Alghetaa et al., 2018).

Statistical analysis

GraphPad Prism (GraphPad Software, San Diego, California USA, www.graphpad.com” Version 8.0) was used to perform different statistical analysis tests on current study data. One-way ANOVA followed by Dunnett’s multiple comparison tests was applied with set of P value less than 0.05 as statistical difference threshold. Statistical differences were depicted as *P<0.05, **P<0.01, ***P<0.001, #P<0.0001.

RESULTS and Discussion

Ameliorative effects of resveratrol treatment on kidney functions

our study results revealed significant (P<0.05) elevation in the serum urea of mercuric chloride intoxicated groups in comparison to control group (Figure 1). While there was no change in the uric acid and creatinine levels in serum of different study groups (not shown).

 

 

Ameliorative effects of resveratrol treatment on the protein profile

In current study results, the toxicity of HgCl2 has led to significant (P<0.05) reduction of albumin (Figure 2A) accompanied with significant increase (P<0.05) in the serum levels of globulin concentrations in HD group in comparison with the HR group as shown in Figure 2B. In other hand, the mercuric chloride toxicity did not change the total protein concentrations in comparison with the other groups (not shown), while total bilirubin level was significantly.

Ameliorative effects of resveratrol treatment on the redox system

Study results showed that there was a significant decrease in total antioxidant capacity (TAC) concentrations in HD group in comparison with HR group. While TAC was significantly (P<0.05) elevated in HR group in comparison with all other study groups (Figure 3).

 

 

Ameliorative effects of resveratrol treatment on the immunological response of mercuric chloride-toxicity in rats

The study results revealed that there was significant (P<0.05) increase in the counts of infiltrating cells into peritoneal exudate of HgCl2-exposed groups in comparison to all non-exposed groups (Figure 4). Interestingly, the resveratrol treatment to HgCl2-intoxicated rats led to significant (P<0.05) reduction in the counts of inflammatory cells in the HR group in comparison to HD group, while administration of DMSO or RES did not drive the immune cells into peritoneal cavity (Figure 4).

During last couple decades, many researchers started to looking for alternative medicine derived from herbal origin to treat most of the modern diseases such as autoimmune diseases, cancers, toxicity and others (Mohammed, 2010; Alharris et al., 2018; Mohammed et al., 2020; Nofal and Fayyad, 2021; Ahmed and Mohammed, 2022a, b). The clinical biochemical parameters Urea, Uric acid, Creatinine are thought to be helpful in determining Kidney toxicity in the Figure 1 we can see the concentration of urea in (HD and RH) group significantly increased than other groups (C, D, R) the considerable increase in serum urea levels after HgCl2 exposure showing its strong nephrotoxic effect, which is thought to be connected to the fact that the kidney collects more mercury than other organs in the body (Abd El-Rhman and Shosha, 2021). The concentration of creatinine and uric acid in sera were not significantly changed. Some authors suggested that since plasma concentrations of total protein, albumin, and globulin are indicators of liver function, decreased serum protein may be due to impaired renal excretion or protein synthesis, or to decreased or impaired liver function (Alsafah and Al-Faragi, 2017). Significant reduction of albumin concentration (2-A) in HD group could be due to decrease in synthesis of albumin or due to the affinity of mercury to bind to the albumin and destroy the physiological function in the blood (Chunmei et al., 2014; Kshirsagar et al., 2015). Reduction of albumin concentration in chemical poisoning conditions is highly correlated with increase of mortality rates (Noh et al., 2021). However, in our study there was no mortality among the study animals may be due to the low dose of HgCl2 and relative short period of exposure (Hu et al., 2021). A significant increase in the concentration of globulin in HD group among other groups (2-B) could be due to increase the body’s defense system reacting to mercury (Al-Zwean, 2014). The onset of the liver damage symptom could be caused by a drop in albumin and elevation of globulin concentrations (Al-Ameedi et al., 2016). In Figure 2C we can see increase in Bilirubin ratio in HD group, a reliable indicator of the hepatotoxicity of toxic materials is an increase in serum bilirubin in intoxicated rats, which is consistent with the findings of (Mohammed et al., 2019; Ahmed and Mohammed, 2022a, b). In the other hand the ratio between urea- albumin and ratio among urea- creatinine there are not change. In the Figure 3 we can see decrease the concentration of Total antioxidant capacity Plasma antioxidants may have decreased TAS in response to increased generation of reactive oxygen species (Lovasova and Sesztakova, 2009; Assumaidaee et al., 2022). The cell types have been hypothesized to originate, at least in part, from local tissues, even though polymorph nuclei leukocytes, which manifest in the peritoneal cavity in reaction to an irritant, are typically regarded to come directly from circulating blood. According to studies, the endothelium of blood arteries, lymph sinuses, and serous membranes were responsible for some of the loose cells that were discovered in the peritoneal cavity. In Figure 4, the number of the peritoneal exudates cells in (HD) Higher than another group.

CONCLUSIONS AND RECOMMENDATION

Chemical poisoning such as mercuric chloride is a health concern that leads to kidney and liver injury even in small traces. Resveratrol is well-known as an antioxidant and anti-inflammatory and could be used as protective supplement during the exposure to mercuric contaminants through mentioned properties. Resveratrol has potent power in ameliorating the parenchymal damage of hepatic. In current study, the supplementation of resveratrol has improved the redox system through increasing the antioxidant yields and suppression of oxidants production. We may recommend introducing the resveratrol-enriched food to the meals of crews who deal with industrials producing chemicals, particularly HgCl2, as products or waste products.
