Abstract
BACKGROUND The comparison of smokeless tobacco (ST) exposure versus Ovalbumin (Ova) sensitized rats or asthmatic patients has hardly been studied in the literature. Thus, the present study aims to investigate the aggravation of inflammation, exacerbation of asthma, oxidative stress and cytotoxicity induced by ST. METHODS ST was given at the dose of 40mg/kg in an allergic asthma model in Wistar rats. Furthermore, the effects of oral administration of Nigella sativa oil (NSO), at a dose of 4mL/kg/day, were investigated. RESULTS The obtained results showed that ST clearly enhanced lung inflammation through interleukin-4 (IL-4) and Nitric oxide (NO) increased production. Actually, ST was found to intensify the oxidative stress state induced by Ova-challenge in rats, which was proven not only by augmenting lipid peroxidation and protein oxidation, but also by altering the non-enzymatic and enzymatic antioxidant status. Furthermore, the aggravation of inflammation and oxidative stress was obviously demonstrated by the histopathological changes observed in lung. In contrast, NSO administration has shown anti-inflammatory effects by reducing IL-4 and NO production, restoring the antioxidant status, reducing lipid peroxidation and improving the histopathological alterations by both protein oxidation and NSO treatment. CONCLUSIONS Our data have proven that severe concurrent exposure to allergen and ST increases airway inflammation and oxidative stress in previously sensitized rats. They also suggest that the oral NSO treatment could be a promising treatment for asthma.

Omar NM, Mohammed MA. The impact of black seed oil on tramadol-induced hepatotoxicity: Immunohistochemical and ultrastructural study. Acta Histochem 2017; 119:543-554. [PMID: 28619287 DOI: 10.1016/j.acthis.2017.05.008] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2017] [Revised: 05/21/2017] [Accepted: 05/29/2017] [Indexed: 12/19/2022]
Abstract
The natural herb, black seed (Nigella Sativa; NS) is one of the most important elements of folk medicine. The aim was to evaluate the impact of Nigella Sativa Oil (NSO) on the changes induced by tramadol in rat liver. Twenty four albino rats were used. CONTROL GROUP given intraperitoneal and oral saline for 30days. TR-group: given intraperitoneal tramadol (20, 40, 80mg/kg/day) in the first, middle and last 10days of the experiment, respectively. TR+NS group: administered intraperitoneal tramadol in similar doses to TR-group plus oral NSO (4ml/kg/day) for 30days. Immunohistochemical, electron microscopic, biochemical and statistical studies were performed. TR-group displayed disarranged hepatic architecture, hepatic congestion, hemorrhage and necrosis. Apoptotic hepatocytes, mononuclear cellular infiltration and a significant increase in the number of anti-CD68 positive cells were observed. Ultrastructurally, hepatocytes showed shrunken nuclei, swollen mitochondria, many lysosomes and autophagic vacuoles. Activated Ito and Von Kupffer cells were also demonstrated. Elevated serum levels of AST, ALT, ALP and bilirubin were noticed. NSO administration resulted in preservation of hepatic histoarchitecture and ultrastructure and significant reductions in the number of anti-CD68 positive cells and serum levels of liver seromarkers. In conclusion, NSO administration could mitigate the alterations induced by tramadol in rat liver.

[PMID: 28273633 DOI: 10.1016/j.biopha.2017.02.044] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2017] [Revised: 02/11/2017] [Accepted: 02/14/2017] [Indexed: 12/22/2022] Open
Abstract
Lead (Pb) is a toxic ubiquitous environmental pollutant that induces hepatotoxicity in both animals and humans. The ability of Nigella saliva seeds (NSS) in ameliorating lead acetate (PbAc)-induced hepatic oxidative damage was investigated using a rabbit model. Forty New Zealand rabbits were given feed and water ad libitum. They were allocated randomly into four groups: control; PbAc (5g/L drinking water); NSS (20g/kg diet) and NSS+PbAc groups. After two months, liver samples were collected and analyzed for malondialdehyde (MDA), glutathione (GSH), glutathione S-transferase (GST) and glutathione peroxidase (GPx) contents. Purification and characterization of GPx were also evaluated. PbAc exposure significantly (p<0.05) increased MDA (lipid peroxidation biomarker) and reduced the GSH levels and the GST and GPx activities. Concurrently supplemented NSS significantly (p<0.05) decreased MDA levels and restored the GSH, GST, and GPx contents successfully. Electrophoretically, the homogeneous GPx preparation from the liver had a specific activity of 30.44 U/mg protein and a yield of 1.31%. The Km values for cumene hydroperoxide were 4.76μM in control, PbAc and NSS+PbAc groups, and 4.09μM in NSS group. The GPx reaction had a temperature optimum 40°C, pH optimum 8 and molecular weight 21 kDa. The obtained data indicated the potent efficacy of NSS against PbAc-induced oxidative stress; that was mediated through induction and activation of antioxidants, particularly GPx and scavenging free radicals. Moreover, the purified hepatic GPx is characterized as a selenoprotein (Se-GPx).

Prophylactic effect of Nigella sativa against lead acetate induced changes in spermiogram, reproductive hormones and gonadal histology of rats. Vet World 2016; 9:1305-1311. [PMID: 27956786 PMCID: PMC5146315 DOI: 10.14202/vetworld.2016.1305-1311] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Accepted: 10/24/2016] [Indexed: 11/16/2022] Open
Abstract
AIM This study was designed to evaluate the prophylactic effect of Nigella sativa (NS) treatment on toxic effects induced by lead acetate (LA) on the reproductive hormones, spermiogram and gonadal histology of rats. MATERIALS AND METHODS A total of 20 Sprague-Dawley rats were divided into four groups of five rats each. Group 1 (negative control [NC]) was the NC and was given distilled water, Group 2 served as the positive control (PC) and was administered 10 mg/kg/day of LA per overall survival (OS), Group 3 (T1) was administered 200 mg/kg/daily of NS per OS for a month, and Group 4 (T2) was pretreated with 200 mg/kg/daily of NS per OS for 1 month, followed by 10 mg/kg/daily of LA alone per OS for another. The rats were euthanized at the end of the experimental period for collection of blood and the right caudal epididymis and testis. Serum was used for determination of reproductive hormones by using radioimmunoassay kits. The epididymal segment was cut and homogenized in phosphate-buffered saline, and the homogenate was used for determination of the spermiogram parameters such as sperm concentration, sperm viability, percentage of live sperm, motility and abnormality. Both the epididymis and testis were fixed in 10% buffered formalin for histological processing. RESULTS The sperm concentration, general, and individual motilities were higher (p<0.05) in the NC and T1 animals, while the T2 had intermediate and the PC had lower (p<0.05) values of each parameter. The percentage sperm viability was higher (p<0.05) in the T1 and lower (p<0.05) in the PC group. However, percentage abnormality was lower in T1, comparable in NC and T2, and higher (p<0.05) in PC. Spermatogenic cell population and epididymal sperm reserve (ESR) were optimal in control and pretreated animals, while the PC had lower spermatids and ESR. The concentration of estradiol (EST) was lower (p<0.05) in the PC and T2, while leuteinizing hormone (LH) concentration was lower (p<0.05) in the PC, and comparable (p>0.05) between control and T2. The concentration of follicle-stimulating hormone (FSH) was comparable (p>0.05) in all groups, while testosterone (TS) hormone concentration was lower (p<0.05) in the PC and higher in the control and T1 groups. CONCLUSION This study showed the preventive effects of NS administration against alterations in reproductive hormnes, sperm parameters and gonadal histology caused by LA in rats.

Abstract
BACKGROUND Liver disease is the major cause of serious health problem leading to morbidity and mortality worldwide and the problem has increased in search for hepatotherapeutic agents from plants. The present study was designed to compare the probable hepatoprotective activity of olive oil and N. sativa oil on CCl4 induced liver damage in male rats. METHODS Forty males of a new model of albino rats (Wistar strain) (175-205 g) were divided into four groups. The 1st Group (G1) was the negative control group, the remaining rats were injected with CCl4 (1 ml/kg body weight) with equal amount of olive oil on the 1st and 4th day of every week for 4 weeks. The 2nd group (G2) was the positive control, the 3rd group (G3) and the fourth group (G4) were treated orally with N. sativa oil and olive oils using stomach tube. RESULTS The positive control group showed an increase in hepatic enzymes, total bilirubin, creatinine, uric acid, lipid peroxide total cholesterol, triglyceride, low density lipoprotein, very low density lipoproteins, interleukin-6, and a decrease in antioxidant enzymes, high density lipoprotein cholesterol, a decrease in total protein and albumin an when compared with negative control group. Histology of the CCl4 treated group revealed inflammation and damage of liver cells. Treating the hepatotoxic rats with olive oil and N. sativa oil showed a significant improvement in all biochemical tests compared with the positive CCl4 control group. In addition, the liver tissues of olive oil treated group showed mild improvement in inflammatory infiltration and in N. sativa oil treated group showed normal hepatocytes with no evidence of inflammation. CONCLUSION This study revealed that olive oil and N. sativa oil have a protective effect against CCl4-induced hepatotoxicity in male rats. Nigella sativa oil was more effective than olive oil.

Abstract
The present study was planned to investigate the protective effects of Nigella sativa oil (NSO) supplementation against aluminium chloride (AlCl3)-induced oxidative damage in liver and erythrocytes of rats. Simultaneously, a preliminary phytochemical study was affected in order to characterize the bioactive components containing in the NSO using chemical assays. The antioxidant capacities of NSO were evaluated by DPPH assay. The results showed that NSO was found to contain large amounts of total phenolics, flavonoids and tannins. Twenty-four rats were equally divided into two groups, in which group A received standard diet, whereas group B treated daily with an oral gavage dose of 2 ml NSO/kg body weight. After 5 weeks pretreatment, both groups were divided again into two subgroups (A and B) of six animals each and treated for other 3 weeks. Therefore, subgroup A1 was served as a control which received standard diet, but subgroup A2 received AlCl3 (34 mg/kg bw mixed with food). Subgroup B1 received both AlCl3 and NSO; however, subgroup B2 received NSO only. Results showed that AlCl3 exhibited an increase in white blood cell counts and a marked decrease in erythrocyte counts and haemoglobin content. Plasma aspartate transaminase, alanine transaminase, alkaline phosphatase and lactate dehydrogenase activities and total bilirubin concentration were higher in AlCl3 group than those of the control, while albumin and total protein concentration were significantly lower. Compared to the control, a significant raise of hepatic and erythrocyte malondialdehyde level associated with a decrease in reduced glutathione content, glutathione peroxidase, superoxide dismutase and catalase, activities of AlCl3 treated rats. However, the administration of NSO alone or combined with AlCl3 has improved the status of all parameters studied. It can be concluded that AlCl3 has induced the oxidative stress, altered the biochemical parameters and the hepatic histological profile, but the supplementation of NSO has alleviated such toxicity.
