Background/Aim: Liver disease constitutes a public health problem at the global level. This study was conducted to evaluate the hepatoprotective effect of the total oil’s unsaponifiable fraction (UF) of a medicinal plant called Nigella sativa. Methods: The extraction of unsaponifiables from the total seed oil of the medicinal plant Nigella sativa was carried out according to the standardized methods of the European Pharmacopoeia (Edition 5.0). Carbon tetrachloride (CCl4) is hepatotoxic with mandatory and predictable action of the indirect type. Acute poisoning of Male albino rats with 1:1 (v/v) mixture of CCl4 and olive oil (3 ml/Kg b.w. of rat by subcutaneous injection) induces considerable liver pain. Results: Nigella sativa UF is found to be rich in tocopherols; its administration as a curative or preventive treatment to poisoned animals results in a very significant reduction in transaminases (ALT, AST) and ALP. Histological study shows that livers are in better condition than those of intoxicated rats. The statute of enzymes and antioxidant molecules (SOD, CATA, GSH, MDA) has significantly improved. Conclusion: Measurable biological evidence has been given to the use of such extract as effective substances against hepatic diseases.

Objective:  The aim of this study is to investigate the ameliorative effect of hydroalcoholic extract of Nigella sativa (HANS) against CCl4-induced hepatotoxicity in albino rats. Methods: Twenty five (25) albino rats, with average weight (105±5g), were randomly grouped into five groups: A-E, of five (5) rats per group. Group A rats served as normal control, Group B (Negative Control) received intraperitoneal administration of carbon tetrachloride CCl₄ (0.4ml/kg, i.p.) only, Group C received CCl₄ and low dose HANS (400mg/kg, oral), Group D received CCl₄ and high dose HANS (800mg/kg, oral), and Group E (Positive control), received CCl₄ and Vitamin C (200mg/kg, oral), for 3 days. Hepatotoxicity was assessed by measuring serum levels of total bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) using standard methods.  Histopathological analysis of the liver was also carried out. Results: The extracts significantly stablized biochemical markers of hepatic injury, and preserved the histoarchitecture of the liver tissues against CCl4 damage. The protective effect was not dose-dependent, as low dose HANS (400mg/kg), showed better protection than the high dose HANS (800mg/kg). Conclusion: Hydroalcoholic extracts of Nigella sativa has antihepatotoxic effects. Keywords: carbon tetrachloride, hepatotoxicity, medicinal plants, Nigella sativa, hydroalcoholic extract

It has been reported that Nigella sativa oil possesses hepatoprotective effects in some models of liver toxicity. However, it is N. sativa seeds that are used in the treatment of liver ailments in folk medicine rather than its oil. Therefore, the aim of this study was to investigate the effect of the aqueous suspension of N. sativa on carbon tetrachloride (CCL4)-induced liver damage. Aqueous suspension of the seeds was given orally at two dose levels (250 mg/kg and 500 mg/kg) for five days. CCL4 (250 μl/kg intraperitoneally/day in olive oil) was given to the experimental group on days 4 and 5, while the control group was only treated with the vehicles. Animals treated with CCL4 showed remarkable centrilobular fatty changes and moderate inflammatory infiltrate in the form of neutrophil and mononuclear cells when compared to the controls. This effect was significantly decreased in animals pretreated with N. sativa. Histopathological or biochemical changes were not evident following administration of N. sativa alone. Serum levels of aspartic transaminase (AST), and L-alanine aminotransferase (ALT) were slightly decreased while lactate dehydrogenase (LDH) was significantly increased in animals treated with CCL4 when compared to the control group. LDH was restored to normal but ALT and AST levels were increased in animals pretreated with N. sativa. In conclusion, N. sativa seeds appeared to be safe and possibly protective against CCL4-induced hepatotoxicity. However, further studies may still be needed prior to supporting its use in folk medicine for hepatic diseases.

The objective of present study was to analyze and compare the nephroprotective effects of petroleum ether extracts of seeds of Nigella sativa and Silybum marianum in Swiss albino mice. Petroleum ether extracts of seeds of Nigella sativa and Silybum marianum were administered (200 mg kg–1) orally for 14 days following one dose of cisplatin injection (16 mg kg–1 i.p.) on 4th day. Cisplatin toxicity was identified in mice by loss of body weight, reduced triglycerides levels, elevated blood glucose, blood urea nitrogen and creatinine levels (P < 0.05). Silybum marianum and Nigella sativa significantly enhanced the body weight (9%) of diabetic rats. Silybum marianum had significantly reduced the elevated blood glucose (–106%), and BUN levels (–9%) as compared to the Nigella sativa administration. Silybum marianum extract also significantly elevated the levels of triglycerides (257%) which were much reduced after the cisplatin injection. Histological study showed that the cisplatin treated group demonstrated the necrosis signs in the glomerulus of Bowman’s capsule, hyalinization and severe cellular damage. The animals administered with extracts showed nearly normal kidney architecture, however, the kidney tissues of Silybum marianum-treated animals showed some improvement with slight signs of cellular damages.

Context. Nigella sativa seeds are usually used as traditional medicine for a wide range of therapeutic purposes. Objective. To investigate the subacute toxicity of NS aqueous extract and select its lowest dose to study its antidiabetic effect. Methods. 5 AqE.NS doses (2, 6.4, 21, 33, and 60 g/Kg) were daily administered to mice by gavage. Biochemical parameters measurements and histological study of the liver and the kidney were performed after 6 weeks of supplementation. Thereafter, and after inducing diabetes by alloxan, rats were treated by 2 g/Kg of AqE.NS during 8 weeks. Metabolic parameters were measured on sera. A horizontal electrophoresis of plasmatic lipoprotein was conducted. Glycogen, total lipids, and triglycerides were measured in the liver. TBARS were evaluated on adipose tissue, liver, and pancreas. Results. AqE.NS showed no variation in urea and albumin at the 5 doses, but hepatotoxicity from 21 g/Kg was confirmed by histopathological observations of the liver. In diabetic rats, AqE.NS significantly decreased glycemia, TG, T-cholesterol, LDL-c, and TBARS and showed a restored insulinemia and a significant increase in HDL-c. Results on the liver indicated a decrease in lipids and a possible glycogenogenesis. Conclusion. AqE.NS showed its safety at low doses and its evident antihyperglycemic, antihyperlipidemic, and antioxidant effect.

Abstract Background Repairing urinary bladder (UB) defect by enterocystoplasty remains the gold standard surgical bladder reconstruction procedure to increase the capacity and compliance of dysfunctional bladders. However, many complications were recorded. Aim of the work This work aimed to compare the consequences of reconstruction of urinary bladder defect using untreated small intestinal submucosal (SIS) matrix versus seeded and unseeded decellularized SIS matrix. Material and Methods Fifty female albino rats were used in this study. The animals were divided into three groups: Group I (Control) included ten adult rats from which ileal tissue was obtained. Group II included ten adult rats in which their UB defect was repaired by untreated cellular SIS. Group III included twenty adult rats that were subdivided into two subgroups, 10 rats each; Subgroup IIIA where rats had their UB defect repaired by acellular SIS and subgroup IIIb where rats had their UB defect repaired by acellular SIS seeded with adipose mesenchymal stem cells (AMSCs).Ten young rats were used for preparation of AMSCs. Morphometric and statistical analysis were also performed. Results In rats where UB defect was repaired by untreated cellular SIS, the graft area showed loss of epithelial polarity, presence of intraepithelial cysts and occasional extension of urothelium to the outer surface forming fistula. There were areas of metaplasia with the appearance PAS positive cells. In the lamina propria, there was areas of lymphocytic infiltration together with significant increase in the collagen fiber deposition (p &lt; 0.05). There was a significant decrease thickness of muscle layer as compared to control (p &lt; 0.05). In rats where UB defect was repaired by acellular SIS, urothelium in the graft area showed occasional squamous metaplasia and often the urothelium extended to the deeper layers forming Brunn's nest. There was minimal muscle regeneration in the graft area. However, in rats where UB defect was repaired by acellular SIS seeded with AMSCs, the urothelium in the graft area was nearly similar to control group with uniform urothelium thickness, minimal collagen fibers deposition and thick muscle layer that showed no significant difference from the control (p &gt; 0.05). Conclusion Acellular SIS seeded with AMSCs showed better results compared to non-seeded and cellular SIS in reconstructing urinary bladder defects.

Hepatocellular carcinoma accounts for about 80–90% of all liver cancer and is the fourth most common cause of cancer mortality. Although there are many strategies for the treatment of liver cancer, chemoprevention seems to be the best strategy for lowering the incidence of this disease. Therefore, this study has been initiated to investigate whether thymoquinone (TQ),Nigella sativaderived-compound with strong antioxidant properties, supplementation could prevent initiation of hepatocarcinogenesis-induced by diethylnitrosamine (DENA), a potent initiator and hepatocarcinogen, in rats. Male Wistar albino rats were divided into four groups. Rats of Group 1 received a single intraperitoneal (I.P.) injection of normal saline. Animals in Group 2 were given TQ (4 mg/kg/day) in drinking water for 7 consecutive days. Rats of Group 3 were injected with a single dose of DENA (200 mg/kg, I.P.). Animals in Group 4 were received TQ and DENA. DENA significantly increased alanine transaminase (ALT), alkaline phosphatase (ALP), total bilirubin, thiobarbituric acid reactive substances (TBARS) and total nitrate/nitrite (NOx) and decreased reduced glutathione (GSH), glutathione peroxidase (GSHPx), glutathione-s-transferase (GST) and catalase (CAT) activity in liver tissues. Moreover, DENA decreased gene expression of GSHPx, GST and CAT and caused severe histopathological lesions in liver tissue. Interestingly, TQ supplementation completely reversed the biochemical and histopathological changes induced by DENA to the control values. In conclusion, data from this study suggest that: (1) decreased mRNA expression of GSHPx, CAT and GST during DENA-induced initiation of hepatic carcinogenesis, (2) TQ supplementation prevents the development of DENA-induced initiation of liver cancer by decreasing oxidative stress and preserving both the activity and mRNA expression of antioxidant enzymes.
