| Abstract|| |
Background: Banisterine (BAN) as an alkaloid agent has antioxidant properties. The morphine (MOR) with the character of free radical generation has an effective role on renal pathogenesis. Objectives: This investigation critically examines the effects of the BAN against MOR-induced damage to the kidneys of rats. Materials and Methods: Sixty-four male Wistar rats were randomly assorted into 8 groups (8 rats in each), including the saline (Sal), MOR, BAN (5, 10, 15 mg/kg) and MOR + BAN treatment groups. All experimental procedures were applied by intraperitoneal injection daily for 20 days. Whole investigated values consist of total animal weight, weight of kidney, morphological criteria of kidney, antioxidant capacity and serum nitrite oxide levels. Results: Intraperitoneally MOR application significantly increased the levels of renal Malondialdehyde (MDA), blood urea nitrogen (BUN), blood creatinine, and blood nitrite oxide and also reduced the glomerular number and tissue ferric reducing/antioxidant power (FRAP) level compared to the Sal control group (P < 0.05). Treatment of BAN and BAN + MOR in all doses significantly reduced the levels of BUN, MDA, creatinine, glomerular diameter, and nitrite oxide and also increased the glomerular number and tissue FRAP levels compared to the MOR group (P < 0.05). Conclusion: The findings support the idea that the BAN with its antioxidant nature can eliminate MOR renal toxicity.

| Introduction|| |
Opioids are generally used for pain relief. Together with their activity, they also produce free radicals causing cellular apoptosis. Morphine (MOR) is a psychoactive chemical available in opium acts as analgesic drug. This drug has addictive effects, thus causes physiological dependence and also has the ability of oxidative stress production. Two significant pathological changes occur immediately after MOR injection, the increased concentration of oxidative stress and enhancement in the lipid oxidase activity. Subsequently, irreversible damage to the cell membrane can be seen.
The high oxidative stress levels result in an imbalance between free radical and antioxidant productions. This unbalanced state causes the oxidation of biomolecules (they promote oxidation reactions with proteins, lipids and DNA and can thus be highly detrimental), changes in cell structure and function. Oxidative stress can deeply alteration such mitochondrial parameters. The oxidative harvests issuing from each biomolecule are multifaceted and manifold. Reactive oxygen species, coming from the reaction of nitric oxide and superoxide anion, are robust oxidants accomplished of destructive lipids, proteins and DNA. Reactivity, the mechanism of manufacture and the products formed vary dependent on the free radical (hydroxyl radical, superoxide anion, Peroxynitrite) and the molecular goal (cholesterol, aromatic, phospholipids, and aliphatic amino acids). Prolonged use of opioids is related to the aggregation of oxidative stress in the kidney. This destructive accumulation leads to the breakdown of nuclear DNA, denaturation of proteins and degeneration of cell membrane. In such a situation, the renal damage will appear.
The kidneys are the main blood purifier organs discharging toxins into urine. The process of toxins and drugs into the urinary system can be influenced by chronic renal disorders. MOR by detrimental renal damage causes an increase in albumin discharge and the emergence of proteinuria conditions. Chronic proteinuria will terminate to renal malfunction.
The Peganum harmala is known as a member of the Zygophyllaceae family. It is cultivated in the vast geographical range from North Africa to the Middle East. The seeds and roots of P. harmala contain alkaloids. Banisterine (BAN) and harmaline are the most abundant alkaloids exist in P. harmala that have therapeutic effects. Totally portions of this plant are believed to be toxic and sever intoxication happens in national animals. Digestive and nervous syndromes have been detected in animals that eat sublethal amount of the plant. The toxicated animal appears in a narcotic state disturbed by occasional short dated of excitement. Harmine (BAN), C13H12ON2, It is existing in P. harmala. The alkaloid is optically inactive and forms colorless rhombic prisms from methanol. Pharmacologically, BAN bear a resemblance to harmaline in its activities however is less toxic. The essence of this plant can be used for the treatment of bradycardia, reduction in blood pressure, adjustment of angiogenesis. Along with their medicinal effects, they act as anti-allergic, anti-spasm and anti-adrenergic agent.P. harmala has been used extensively in the field of traditional medicine, for example menstrual cycle regulator, food appetizer, annihilator of parasites. BAN is an active component of P. harmala with alkaloid property as a member of the beta-carboline family. The BAN substance is derivate from P. harmala and is completely known as antioxidant. It is an active controller of tyrosine phosphorylation-regulated kinase (DYRK) enzyme, which is involved in the adjustment of mitosis evasion, apoptosis, transcription factors and pro-inflammatory cytokines. For this reason, in human tumor cells the BAN shows cytotoxic activity. Besides, it can suppress TNF-α activity and nitrite oxide production as oxidative stress agents.
It has been found that the levels of MOR in the body lead to an increase in the level of nitrite oxide and oxidative stress. Various approaches have been suggested the toxic trace of MOR along with beneficial effects of BAN. There are not enough surveys on the therapeutic impact of BAN on renal diseases. Thus, this study will provide a clear attitude whether BAN alleviates the MOR-related renal toxicity by antioxidant pathways in animal male Wisar rats.
| Materials and Methods|| |
The present experiment was carried out in the Anatomy Department of the Kermanshah University of Medical Faculty from May 2018 to December 2018. A total of 64 male Wistar rats weighting 250–270 g and 8 weeks old were purchased from Pasteur Institute of Iran (IPI, Tehran, Iran). The nutritional and ideal living conditions for laboratory animals were provided as follows: plastic cages with access to water and food pletes freely, room temperature around 23°C ± 2°C, with a relative humidity of 50% ± 5% and 12 day/12 night diurnal cycle. All experimental processes were conformed to the ethical and humane principles of research and also were approved by the Ethics Committee of Kermanshah University of Medical Sciences (ethics certificate no. 1395.38).
Study design and treatments
All treatments were applied through intraperitoneal injection. Three types of treatment doses were prescribed. The MOR injection in which a single dose of 20 mg/kg for the first 5 days, a double dose of 20 mg/kg daily for the second 5 days and a double dose of 30 mg/kg daily for the remaining 10 days were administered. The BAN injections were 5, 10 and 15 mg/kg daily for 20 days. The saline (Sal) injection, which administered just for control group is equivalent to the amount of experimental groups. Eight random groups with 8 rats in each were selected. The groups were respectively included the Sal (control group), MOR group, BAN groups (three groups of 5, 10 and 15 mg/kg), BAN + MOR groups (three groups of 5, 10 and 15 mg/kg).,
Weight of rats, kidney and blood serum collection
Total body and renal weight were measured by a microbalance (Precisa 125A; Switzerland) at the first and end of the study.
In this process, animals were intraperitoneally anesthetized with a single dose of ketamine/xylazine (100/10 mg/kg). To collect the blood through the right ventricle, the thoracotomy procedure was done. The blood sample was aspirated and incubated for 15 min at 37°C to form clot. Then the centrifugation was applied at 3000 rpm for 15 min. The separated serum was stored at −70°C for the measurement of the biochemical factors.
Histological and morphometric analysis
A vertical incision was made on kidneys in order to the creation of two equal parts. The samples of kidneys were fixed by infiltration of 10% formalin solution for a week immersion. The conventional histological tissue process was run and 5 μm serial sections were prepared (microtome, EC350-2). The staining was applied by Hematoxylin and Eosin. The diameter and number of glomeruli were examined by a microscope linked to a DP12 camera (Olympus BX-51T-32E01 with 3.34-million pixel resolution). The morphometric features were analyzed by Olysia Bio software (Olympus Optical; Japan).
Biochemical marker assays
The concentrations of creatinine and blood urea nitrogen (BUN) exist in blood samples were analyzed biochemically (autoanalyzer, RA 1000; Technicon Instruments; USA).
Nitrite oxide assay
In this technique, zinc sulfate powder was added to eliminate the proteins of blood serum. 6 mg powder of zinc sulfate was mixed with 400 μl of serum samples and centrifuged (12,000 rpm, 10 min). The nitrite oxide available in supernatant was measured. The previous sample (50 μl) was added to Griess reagent (100 μl, Sigma; USA). Then, it was incubated (30 min at room temperature). The ELISA reader (Hyperion; USA) device measured the sample optical density at the wavelength of 450 nm.
Biochemical techniques of ferric reducing/antioxidant power and malondialdehyde
Based on the colorimetric analysis, the specious of thiobarbituric acid reactive were measured by the means of malondialdehyde (MDA) (last product of lipid peroxidation) in renal tissue to evaluate the levels of oxidative stress. The ferric reducing/antioxidant power (FRAP) technique was hired for the measurement of antioxidant capacity in kidney. 1.5 ml of chloride ferric (Sigma, USA) and 30 ml of acetate buffer (Sigma, USA) were available in FRAP substance. Serial concentrations of FeSO4.7H2O (Sigma, USA) were considered as an external standard.
The Kruskal–Wallis test was hired to examine data normality and homogeneity. Statistical comparisons were investigated via one-way analysis of variance, followed by the least significant difference post hoc test. The value of P < 0.05 was considered as statistically significant. All statistical analysis was done by SPSS software (version 16.0, SPSS Inc., Chicago, IL, USA).

Total weight of animals and kidneys
There was a clear trend of total weight and the kidney weight of treated animals as follows. The results of animal weathering offered a significant improvement in total weight of animal and weight of kidneys in all administered doses of BAN (5, 10, 15 mg/kg) compared to the MOR (P < 0.05). No significant changes in the mean total weights of animal and kidney revealed in BAN treated animals in all doses (5, 10, 15 mg/kg) was revealed in comparison with the Sal group (P > 0.05). These two types of weighted variables were decreased significantly in animals treated with BAN + MOR in all doses (5, 10, 15 mg/kg) in comparison with the Sal group (P < 0.05). These variables were increased significantly in animals treated with BAN and BAN + MOR in all doses (5, 10, 15 mg/kg) in comparison with the MOR (P < 0.05). Moreover, the effective dose of MOR was significantly decreased the mean total animal and kidney weight compared to the Sal group (P < 0.05) [Figure 1].

Histological and morphometrical assessments
The normal structure of kidney was detected in Sal and BAN treated groups. Histological observation revealed the disorganization of renal structure by MOR like an increase in the size of Bowman's capsule and distal and proximal tubules and also the count of glomeruli and intertubular bleeding were decreased. In [Figure 2], the obvious data were presented indicating that the treatment in all doses (5, 10, 15 mg/kg) of MOR + BAN reduced the renal damage caused by MOR-related toxicity. According to morphometric concepts and the comparison to the Sal group, the mean diameter of the glomerulus tubule and the number of glomerular (P < 0.05) were improved and decreased, respectively. The BAN treatment increased the diameter of the glomeruli significantly (P < 0.05) while no significant effects on the number of glomeruli in all treatment groups (5, 10, 15 mg/kg) were detected compared to the Sal group (P > 0.05). The number of glomeruli in BAN + MOR treatments was significantly decreased (P < 0.05) while no significant influence on diameter of glomeruli in all treatment groups compared to the Sal group (P > 0.05) were detected. The histological alteration following BAN and BAN + MOR administration were clearly recognizable [Figure 3], indicating that the diameter of the glomeruli in the above-mentioned groups of MOR was decreased and the number of glomeruli was increased significantly compared to the MOR group (P < 0.05) [Figure 2] and [Figure 3].

According to the further biochemical trials, the MOR (with the dose of 2.5 ml/kg) significantly increased the concentration of BUN and creatinine compared to the Sal group (P < 0.05) while the BUN and creatinine presented no significant changes in all doses (5, 10, 15 mg/kg) of BAN in comparison with Sal group (P > 0.05). According to [Figure 4], the BUN and creatinine concentrations were increased significantly in all BAN + MOR groups (5, 10, 15 mg/kg) compared to the Sal group (P < 0.05) and were decreased significantly in all BAN and BAN + MOR (5, 10, 15 mg/kg) groups compared to the MOR group (P < 0.05) [Figure 4].

Nitrite oxide assay
It is apparent that the average level of serum nitrite oxide was increased significantly in the MOR (2.5 ml/kg) group compared to the Sal group (P < 0.05) while it showed no significant changes in all BAN and BAN + MOR groups compared to the Sal group (P > 0.05). The mean serum level of nitrite oxide decreased significantly in all BAN and BAN + MOR groups (5, 10, 15 mg/kg) compared to the MOR group (P < 0.05) [Figure 5].

Oxidative Stress and ferric reducing/antioxidant power assessments
The level of renal MDA was significantly increased in the MOR group compared to the Sal group (P < 0. 05). On the other hand, BAN decreased significantly the renal MDA level in all treatment groups (5, 10, 15 mg/kg) compared to the MOR group (P < 0.05). The renal MDA level was decreased significantly in all BAN + MOR groups (5, 10, 15 mg/kg) compared to the MOR group (P < 0.05). Similarly, MOR significantly reduced the renal tissue FRAP level in the MOR group compared to that of the Sal group (P < 0.05). BAN increased the FRAP level in the kidney in all BAN and BAN + MOR groups (5, 10, 15 mg/kg) compared to the MOR group (P < 0.05). In all groups of BAN, no significant changes in the renal tissue FRAPS and MDA levels were found compared to the Sal group (P > 0.05). Treatment with BAN + MOR significantly increased the renal MDA level (P < 0.05) while no significant effect on the renal tissue FRAPS level in all treatment groups (5, 10, 15 mg/kg) was found compared to the Sal group (P > 0.05) [Figure 6].

| Discussion|| |
Chronic renal disease is a general health problem that affects all body organs including kidneys. A severe renal pain clinically alleviated by administration of MOR. Additionally, the MOR has pathogenesis effects on induction of renal deceases. BAN is an herbal alkaloid and a member of the Beta carboline family (extracted from P. harmala). This plant has various therapeutics effects in traditional medicine.
The findings of the present survey will help us to understand whether the BAN extract has restorative effects on nephrotoxicity caused by increase MOR dosage in male Wistar rats. According to the results, there has been a gradual increase in total weight and kidney weight of MOR-receiving rats in comparison with the Sal group. Meanwhile, this incremental trend was observed in all doses of BAN + MOR groups compared to the MOR group. The stimulatory effect of MOR on release of dopamine, serotonin and γ-amino butyric acid in bloodstream and basic metabolism level of body and also inhibitory effects in appetite has been proved. A recent study reported by Arany et al. supported this hypothesis that MOR decreases body weight. Arany et al. concluded that MOR with a high-fat diet regime decreased their body weight and BMI. It appears that MOR causes metabolism-induced generation of free radicals, lipid peroxidation, DNA destruction and cell membrane proteins, which finally causes cell damage. This phenomenon subsequently leads to weight of body and kidney loss. On the contrary, some papers confirm our conclusion about increasing the body weight by BAN consumption. For example, Hamden et al. found that P. harmala recovers weight loss in rats treated with thiourea. Scientists have seen that the BAN by binding to receptors such as mono amino oxidase, serotonin 2A and kinase-dependent syncline improves the food absorption and total weights of body and kidney.
The results obtained from the preliminary analysis of consumption of MOR alone revealed that MOR increases and decreases the glomerular diameter and number respectively. However, in MOR + BAN treated groups the glomerular diameter decreased and the number increased significantly compared to the MOR groups. These significant changes prove that the glomeruli are strongly sensitive to oxidative stress caused by MOR. MOR is a vigorous carcinogen that is oxidized into cotinine metabolites largely in the liver, kidneys, and lungs. Cotinine can run a critical role in the pathogenesis of tissue. MOR causes these changes with the application of cytochrome P450 and production of free radicals and oxidative stress in tissues. Lipid peroxidation and subsequent free radicals accumulation can change three-dimension structures of proteins and damage DNA and can induce apoptosis in renal tissue cells, vascular and tubular damage., The reduced average diameter and the number of glomeruli are found in renal function disorders. Jalili et al. in an experimental study reported that oxidative stress caused by mitochondrial degeneration leads to an increased concentration of cytoplasmic calcium. The alteration in biochemical hemostasis in cells, in addition to interfering with cytoskeleton arrangement and cellular metabolism, can even lead to initiation of intracellular enzymes activity like proteases, endonucleases and phospholipases. All cellular fluctuations as explained earlier resulting in necrosis of tubular epithelial cells. The previously mentioned results correlate with those observed in the present study indicating that the BAN due to its antioxidant property largely neutralizes the oxidative stress effects of MOR. Thus the physiological number and diameter of glomeruli will be established, whereas the sole prescription of MOR increased BUN and creatinine. The combined application of MOR and BAN will significantly decrease the creatinine and BUN levels compared to the MOR group. The increased levels of BUN and creatinine may act as a signal to cause glomerular damage and disturb renal filtration capacity., The results of this study agree with the findings of other studies such as Osborne et al. which showed that the MOR increases the levels of BUN and creatinine. BAN can reduce the degenerative effects of MOR and prevent renal failure due to the reduction in the rate of oxidation and free radicals production.
The level of nitrite oxide Evaluation indicated a significant increase in the level of nitrite oxide in MOR compared to Sal group. Prescription of BAN + MOR significantly decreased the nitrite oxide level. It is hypothesized that the MOR by discharge of noradrenaline in the paraventricular, amygdala and solitary nuclei stimulate the generation of nitrite oxide. The nitrite oxide by means of cellular mechanisms can enhance the excessive entry of calcium to cytosol which switches the physiological status of cells to the toxic form. Based on the evidences, excessive production of nitrite oxide and the increased iNOS and nNOS expression induce nephrotoxicity, nephritic and nephrotoxic diseases. NOS isoform is normally expressed in the kidney. If overexpression of NOS isoform occurs, the thickness of the distal tubules, proximal tubules and urine collecting tracts will increase. Antioxidants can diminish the rate of nitrite oxide production through disruption in the nitrite oxide system. As noted by El Madaniet al. the BAN prescription significantly decreases the serum level of nitrite oxide in the rats treated by rotenone.
The results of the current study reveal that the BAN as an antioxidant agent can lead to the alleviation of MOR -induced damage in renal tissue. Also, the BAN inhibits the induction of renal inflammation by reduction in serum level of nitrite oxide and increasing the total antioxidant capacity. The findings of the present study suggesting that the BAN can moderate lipid peroxidation and increase the activity of anti-oxidant in kidney. Therefore, there are several important changes by recruitment of anti-oxidant properties of BAN including an increase in FRAP and decrease in MDA levels.
| Conclusion|| |
The most prominent finding to emerge from this study is that the BAN recovers the nephrotoxicity condition caused by MOR application. Generally, these findings strongly support this hypothesis that the BAN acts as a valuable renal protective agent for individuals who have been exposed to MOR. This therapeutic effect is provided by antioxidant properties of BAN. Further investigations and experimentation into the molecular mechanism of BAN in renal MOR-toxicity are recommended.
