Garlic, scientifically known as Allium sativum, has been a revered traditional medicine for millennia, rich in diverse phytochemicals with various medicinal properties, such as antioxidant, anticancer, anti-inflammatory, pain killer, hypoglycemic, antimicrobial, antiviral, and wound-healing properties. Its remarkable therapeutic potential makes garlic a beneficial natural treatment for many health issues.

This research examined the neuroprotective effects of garlic against Malathion (Mal)-associated Parkinson's-like behavioral symptoms in rats.

Animals were categorized into eight groups at random: (1) saline-treated group (control); (2) Mal group (100 mg kg⁻¹); (3) Mal + garlic (50 mg kg⁻¹); (4) Mal + garlic (100 mg kg⁻¹); (5) Mal + garlic (150 mg kg⁻¹); (6) Mal + L-DOPA (10 mg kg⁻¹); (7) garlic (150 mg kg⁻¹); and (8) polyethylene glycol (PEG) group (L-DOPA vehicle). Treatment lasted 28 days, followed by behavioral assessments and analyses of acetylcholinesterase (AChE) activity, malondialdehyde (MDA) level, antioxidants levels, and proinflammatory cytokines in the striatum.

Mal exposure caused neurobehavioral toxicity with increased MDA, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6), alongside decreased GSH concentration and AChE activity. Garlic treatment successfully mitigated these effects.

The findings suggest that garlic may have a favorable impact in treating Parkinson's disease by enhancing antioxidant levels and mitigating oxidative stress and inflammatory processes, countering the harmful effects of pesticides like Mal. Additional studies necessary to thoroughly explore garlic's protective benefits in this area.

Ricinus communis L, commonly known as the castor oil plant, is a valuable traditional medicine that has been used for thousands of years around the world. The plant contains a diverse range of phytochemicals with various medicinal properties, including anti-oxidant, anti-cancer, anti-inflammatory, central analgesic, anti-diabetic, anti-microbial, anti-viral, and wound healing activities. Its many beneficial compounds make it a valuable natural remedy for numerous health conditions.

The present study investigated the preventive effect of castor oil on malathion-induced Parkinson's disease (PD)-like behaviors in rats.

Rats were divided into 8 groups: Control (normal saline), malathion (100 mg/kg/day, intraperitoneal injection (IP)), castor oil (0.05, 0.1, or 0.5 mL/kg/day, orally) plus malathion, levodopa (10 mg/kg/day, IP) plus malathion, castor oil (0.5 mg/kg/day, orally), and polyethylene glycol (PEG) (vehicle of levodopa) groups. All treatments were administered for 28 days, after which neurobehavioral tests such as open field, rotarod, and catalepsy were performed. The activity of acetylcholinesterase (AChE) in serum and the levels of malondialdehyde (MDA), glutathione (GSH), tumor necrosis factor α (TNFα), and interleukin (IL)-6 in the striatum were measured at the end of the treatment period to assess the potential effects of castor oil.

The finding of this study indicated that malathion-induced neurobehavioral toxicity was together with the increase of MDA, TNFα, and IL-6 levels, a decrease of GSH, and AChE activity that was reversed by treatment with castor oil.

Overall, these results suggest that castor oil may have potential therapeutic effects for PD by improving antioxidant status and reducing oxidative stress and inflammation, which are both factors that can contribute to the toxicity of pesticides like malathion. However, more research is needed to fully understand the potential protective effects of castor oil in this context.

Many people in agricultural industry are nowadays struggling with protecting their products utilizing pesticides. Pesticides, such as organophosphate (OPE) insecticides, may remain on agricultural products as pesticide residues. Malathion (MTN) is an OPE widely used around the world. Some OPEs, such as parathion (PTN), are more toxic pesticides and have been restricted. Carvacrol (CRL) is a major component of Satureja khuzestanica essential oil, whichexerted protective effects against toxicity of chemicals. OPEs can alter lipid profile. In addition, lipid profile may alter due to certain disorders, such as nephrotic syndrome. The present study aimed to investigate the effects of coadministration of CRL and the effect of these two pesticides on serum acetylcholinesterase (AchE) activity and lipid profile in male wistar rat. Coadministration of CRL and PTN, but not MTN, significantly decreased serum AchE activity in comparison with the group receiving OPE. Serum levels of cholesterol and triglyceride were analyzed after 10 days of administration of the chemicals. Malathion and PTN significantly increased cholesterol and triglyceride. However, administration of CRL modified lipid profile (P < 0.05). It was concluded that CRL could be considered as a drug to treat lipid profile alteration and owing to the beneficial effects as well as inhibition of acetylcholine, it could be considered as a component of OPE pesticide.

In this study, the protective effect of crocin on malathion (MTN) induced cardiotoxicity in rats in subacute exposure was evaluated. Rats were divided into 6 groups; control (normal saline); MTN (100 mg/kg); MTN + crocin (10, 20 and 40 mg/kg) and MTN + vitamin E 200 IU/kg. Treatments were continued for two weeks. Creatine phosphokinase MB (CK-MB), malondialdehyde (MDA) and glutathione (GSH) levels were evaluated in heart tissue at the end of treatments. The effect of crocin and MTN on histopathological changes in rat cardiac tissue was also investigated. The alteration of protein profile in the heart of the animals exposed to MTN was evaluated by proteomic approach through two-dimensional gel electrophoresis followed by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) software. MTN induced histopathological damages and elevated the level of cardiac marker CK-MB (P < 0.01). The level of MDA increased and the level of GSH reduced (P < 0.001). MDA levels were reduced in all crocin plus MTN groups (P < 0.001) and vitamin E plus MTN (P < 0.001) groups as compared to MTN groups. However, in the crocin (10 mg/kg) + MTN group, the content of GSH compared to MTN treated rats increased (P < 0.001). Protein abundance analysis identified proteins implicated in cardiac necrosis, tricarboxylic acid cycle, cellular energy homeostasis, arrhythmias, heart development, heart failure and cardiovascular homeostasis to be affected by MTN. In summary, MTN may induce damage in the heart tissue of rats following subacute exposure and crocin, as an antioxidant, showed protective effects against MTN cardiotoxicity.

Malathion is an organophosphorous insecticide widely used in agriculture, residential area and public health programs with a known mechanism of toxicity of inhibition of acetylcholinesterase and induction of oxidative stress. Gold nanoparticles (AuNPs) represent a stable and easily synthesized nanoparticles with extensive use in consumer products and medicine. Due to antioxidant property of AuNPs, it is possible that AuNPs may prevent malathion-induced oxidative damage. In this study, the cytotoxicity of malathion and AuNPs (10 and 20 nm) were measured separately in Caco-2 cells. Then the protective effects of AuNPs were evaluated by measuring the oxidative stress (lipid peroxidation level and glutathione content), and acetylcholinesterase activity. The calculated IC50s values at 48 hr were 326.8±0.32, 43.09±0.65, and 41.46±0.24 µg/ml for malathion, AuNPs 10 and 20 nm respectively. Then, the lowest concentration of AuNPs (1 µg/ml) and IC50 concentration of malathion (326.8 µg/ml) were selected to evaluate the effects of pretreatment of Caco-2 cells with AuNPs before exposure to malathion were evaluated. Interestingly, the results showed remarkably significant protective effects of AuNPs by attenuation the different parameters of oxidative stress and cytotoxicity induced by malathion in cells (p<0.001). It is the first report showing protective effects of AuNPs against malathion-induced cytotoxicity in Caco-2 cell line.

Studies have shown that organophosphorus pesticides such as malathion induces oxidative stress injury and tissue damage. 

This research aimed to determine the effects of the hydroalcoholic extracts of Satureja avromanica (SA) on the liver function of malathion-poisoned animals.

Twenty-eight rats were divided into four groups of the control, SA (20 mg/kg), malathion+SA, and malathion. Animals received malathion 150 mg/kg and SA 20 mg/kg for one week through intraperitoneal injection. Then, their liver and blood samples were extracted, and alanine aminotransferase, aspartate aminotransferase concentrations in serum as well as biomarkers of oxidative stress such as Lipid Peroxidation (LPO), Total Antioxidant Capacity (TAC) and Total Thiol Groups (TTG) in the liver tissue were measured. 

The results showed that the SA administration reduced the level of liver LPO compared with that in the malathion group. Also, receiving SA increased liver TAC and TTG levels in rats, which this difference was significant compared with the malathion group. Besides, the SA group showed a significant decrease in liver enzyme levels, compared with the malathion-treated group.

According to the results, SA exerted protective effects against malathion poisoning, through reduction of oxidative stress. Therefore, SA may be an antioxidant to counteract the harmful effects of malathion poising in liver tissue.

The aim of this study was to determine the protective role of ascorbic acid on apoptosis and proliferation of spermatogonia and primary spermatocyte cells after malathion administration as an organophosphate pesticide in rat testis.

Thirty male Wistar rats were randomly divided into five groups of 6 rats each, including control (no intervention), sham (normal saline 0.09%), malathion (50 mg/kg), malathion plus ascorbic acid (50 mg/kg and 200 mg/kg, respectively), and ascorbic acid (200 mg/kg) groups. Malathion and ascorbic acid were administrated via intraperitoneal injection once per day and seven times per week. After 6 weeks, animals were sacrificed, and testis tissue was used for evaluation of apoptosis and proliferation of germinal epithelium cells using the TUNEL and PCNA staining techniques.

The results of TUNEL staining showed that the numbers of apoptotic cells in spermatogonia and primary spermatocyte cells were significantly increased in the malathion 50 mg/kg group vs control group (P<0.001). Co-administration of malathion 50 mg/kg and ascorbic acid 200 mg/kg significantly decreased the apoptotic cells in both cell types in comparison with malathion 50 mg/kg group (P<0.001). The results of PCNA staining revealed that the proliferation of these cells was significantly decreased in malathion 50 mg/kg group vs control group (P<0.001), and malathion 50 mg/kg plus ascorbic acid 200 mg/kg administration increased the proliferation of cells compared with malathion 50 mg/kg group (P<0.001).

The results provide evidence that ascorbic acid showed preventive effects on malathion-induced toxicity in male rat testis.

 Organophosphorus pesticides are one of the widely consumed poisons in agriculture. The consumption of drinking water, which contains an excessive amount of poison, therefore, contributes to adverse health and hygiene outcomes in humans.

 In this study, a new sodium alginate/biosilicate/magnetite (SABM) nanocomposite made by the precipitation method was used to remove Malathion from aqueous solutions. The properties of MBSA were analyzed using XRD, SEM, EDX, and FTIR techniques. The possible impact of several parameters such as contact time, pH, initial Malathion concentration, temperature, and MBSA dosage on the adsorption process were investigated. The equilibrium isotherm and kinetic models were employed to evaluate the fitness of the experimental data.

 The highest removal (94.82%) of MBSA was obtained at an optimum pH of 7, the contact time of 120 minutes, the adsorbent dosage of 4 g/L, Malathion concentration of 10 mg/L, and temperature of 318°K. The adsorption process followed the Freundlich isotherm model (R2 = 0.999), which implied that the adsorption process of Malathion molecules onto MBSA might be mainly a multi-molecular layer.

 The results of this study showed that MBSA had a good removal efficiency, lower cost of processing, and as well as not producing substances harmful to the environment, which make it a promising adsorbent to remove Malathion from aqueous environments.
 

Malathion is the most organophosphates which capable to produce free radicals and induce disturbance on some of male reproductive parameter. Resveratrol is an herbal polyphenol and it has been beneficial antioxidant effects during short-term administration. This study was designed to evaluate the effects of Resveratrol against damage induced by Malathion to the reproductive parameter of male rats.

In this experimental study, 48 male rats were randomly assigned to 8 groups: normal control (saline) and Malathion control (250 mg/kg) groups; Resveratrol groups (2, 8, 20 mg/kg) and Malathion + Resveratrol (2, 8, 20 mg/kg). Treatments were administered intraperitoneally and gavage daily for 65 days. The sperm parameters, testis malondialdehyde (MDA), total antioxidant capacity (TAC), testosterone level and germinal layer height were evaluated and statistically analyzed.

The results displayed that the values of all parameters except MDA level (which increased) reduced significantly in the Malathion control group compared to the normal control group (p < 0.001). The Resveratrol and Resveratrol + Malathion treatments at all doses increased significantly all parameters except MDA level (which decreased) compared to the Malathion control group (p < 0.001). No significant modifications were observed in all Resveratrol groups compared to the normal control group (p > 0.05).

Resveratrol attenuates toxic effect of Malathion on some of male reproductive parameters.

Malathion is one of organophosphate pesticides that is widely used in agriculture and crops to control insects. Malathion affects body organs such as the reproductive system by inhibiting acetylcholinesterase activity and induction of oxidative stress. This study is aimed to investigate the effects of malathion on glutathione (GSH) and malondialdehyde (MDA) level in testis of male rats, as well as to study the protective role of Ascorbic Acid. In this study, 30 adult male Wistar rats weighing approximately 200–250 g were divided into 5 groups of 6 rats each. These groups include a control group (no intervention), sham (normal saline 0.9%), experimental Group 1 (malathion 50 mg/kg), experimental Group 2 (Malathion 50 mg/kg + Ascorbic Acid 200 mg/kg), and experimental Group 3 (Ascorbic Acid 200 mg/kg). Malathion, solvents, and ascorbic acid were injected intraperitoneally. After 6 weeks, all groups were anesthetized, and the right testis was used to measure levels of MDA and GSH. MDA as a marker of lipid peroxidation and GSH content was used. The results showed that malathion increased MDA level and decreased GSH level compared with the control group (P < 0.001). It was also found that administration of malathion in combination with ascorbic acid reduced MDA level and increased the GSH level. Malathion‑induced lipid peroxidation and oxidative stress in the testis of rats. In addition, it seems that ascorbic acid, due to its antioxidant capabilities, can improve malathion‑induced poisonous changes.

Malathion is an organophosphorus pesticide that commonly used in many agricultural and non-agricultural processes. Previous studies have reported the effects of melatonin on the reproductive system. Cerium dioxide nanoparticles (CeNPs) due to their antioxidative properties are promising to impact on the development of male infertility.

The aim of this study was to evaluate the effect of CeNPs on oxidative stress and sperm parameters after malathion exposure of male rats.

36 adult male Wistar rats were divided into 6 groups (n=6/each): Control, CeNPs -treated control (15 and 30 mg/kg/day), malathion (100 mg/ kg/day), and CeNPs -treated malathion groups (15 and 30 mg/ kg/day). At the end of the study (4 wk), the sperm counts, motility, and viability in the testis of rats were measured, also lipid peroxidation, total antioxidant capacity, and total thiol groups in homogenate testis were investigated.

Malathion significantly reduced sperm count, viability, and motility than the control rats (p

CeNPs 30 mg/kg administered considerably restored testicular changes induced by malathion. The improvement of oxidative stress by CeNPs may be associated with increased sperm counts, motility and viability in the testis.

Regardless of toxicity of nanoparticles, cerium oxide nanoparticles (CeNPs) are emerging as a multi-functional agent for biomedical purposes. On the other hand, Organophosphorus pesticides, like malathion, are inevitably found in the environment. The common involving pathway CeNPs and malathion share is oxidative stress. Therefore, we conducted this study to find the possible neutralizing or synergistic effects of CeNPs on oxidative stress responses in malathion-induced toxicity by intraperitoneal (IP) injection. In this experimental study, 40 Wistar male rats with the weight range of 200-250 g were randomly selected and divided into eight groups. Group1 (control, normal saline), group2 (100 mg/kg/day malathion /IP), group3 (15 mg/kg/day CeNPs/IP), group4 (30 mg/kg/day CeNPs /IP), group5 (60 mg/kg/day CeNPs /IP), group6 (100 mg/kg/day malathion+15 mg/kg/day CeNPs /IP), group7 (100 mg/kg/day malathion+30 mg/kg/day CeNPs /IP) and group8 (100mg/kg/day malathion+60 mg/kg/day CeNPs /IP). After 4 weeks of treatment, the levels of lipid peroxidation (LPO), total antioxidant capacity (TAC), total thiol molecules (TTM) and activity of catalase (CAT) in lung tissue were measured. All data were analyzed by SPSS V16 and One way ANOVA with Tukey post hoc test. The results demonstrated that CeNPs caused significant increases in LPO and TAC, in a dose-dependent-manner. For TTM level, none of the groups presented any significant change compared to control. Significantly decreased levels of CAT, also, were seen in all treatment groups. Surprisingly, all animals of group 8 died. Worth of noting, groups receiving combined CeNPs and malathion showed severe responses for these parameters. These results discovered that CeNPs induces oxidative stress parameters and ROS production, especially combined with malathion in lung tissue. Groups receiving both CeNPs and malathion displayed synergistic toxic properties. LPO, TAC and CAT seem to be better parameters for measuring CeNPs-induced responses. Further investigations are required to shed light on clear mechanisms involved

Malathion is an organophosphate insecticide and is the most appropriate one used widely in the world. Organophosphate insecticides cause a specific biochemical defect in the body. A major cause of this wastage is inhibition of cholinesterase (ChE) enzyme.
This study was conducted to determine the optimal dose of the pesticide malathion which inhibited 50% of ChE enzyme.
An experimental study was conducted on 18 male rats weighing 180-250 g. The rats were randomly divided into 6 groups. The Ellman method was used to measure the acetylcholinesterase (AChE) enzymatic activity. Doses 0, 25, 50, 100, 200 and 400 mg/kg of pesticide malathion was tested on rats to determine the dose of the pesticide malathion with 50% inhibition of the ChE enzyme, at 24, 48, and 72 hours. According to these data, Emax model was fitted, then the median effective doses of the pesticide malathion were estimated at different time intervals, separately.
Based on the reduction Emax model, the optimal dose 29.14 mg/kg was determined at 72 time point.
Using the mixed effect Emax model instead of the multiple comparison methods, such analysis of variance was suggested to determine the optimal dose of organophosphates such as malathion, which provide more accurate results.

Malathion (MAL) is a choice insecticide in the stored grain in different countries. The aim of the present study is to evaluate toxicological effects of 30-day intake of MAL on the male reproductive system of Wistar rats.
This research was ethically approved by the local authority at Faculty of Medicine, Monastir, Tunisia. Three MAL treated groups received 1 ml corn oil containing 1.3, 13.7, and 137 mg/kg body weight/day, respectively. Body and testes weights, testosterone, Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) levels were measured. Histopathological sections were prepared from testes of animals and stained with hematoxylin and eosin and also Masson trichrome. Statistical analysis was done using SPSS for windows version 10.
A meaningful decrease (p0.05) was found between body weight of control and treatment groups. All the three MAL-treated rats had significantly (p Our study revealed that subchronic and relatively short time exposure of male Wistar rats to MAL can induce histopathological changes in testes and disturbance in sex hormones levels in a dose-dependent manner.
