Significant Protective Effect

Acetaminophen has contributed to acute liver failure disease in more than half of the USA and Britain but as an analgesic and antipyretic it is very effective. For many decades in Europe, Middle East and Africa, Nigella sativa has been used for various medical purposes, it is part of the botanical family Ranunculaceae of Gently sloping plants, and is called black cumin seed., Nigella sativa conjugated sterols could be used as precursors to many hydrosoluble steroids for hemisynthesis. The aim of the Study is to examine the promising hepatoprotective effects of Nigella sativa against Acetaminopheninduce hepatotoxicity in mice in this experiment Forty adult male albino mice, incorporated in the experiment and Acetaminophenwas used to induce hepatotoxicity in a dose of 1 gm /kg by the oral route. A number of biochemical and histopathological tests have been used to evaluate liver damage and Nigella sativa protective effects. The result showed a significant protective effect of Nigella sativa against acetaminophenhepatotoxic effect as Nigella sativa in this study tended to normalize the serum levels of liver enzymes, and the protective effects observed clearly by the histopathological evaluation confirming that it effectively protected mouse livers against severe damage caused by acetaminophen. Conclusion in our study it shows that Nigella sativa have a very significant protective effects against acetaminophen induced liver toxicity which is recommended to be fully investigation on human especially to people on risk of acetaminophen liver toxicity

Black cumin seeds are known to have beneficial contents as antibacterial. This study aimed to determine the effectiveness of black cumin seed extract (Nigella sativa) on the growth of Klebsiella pneumoniae and Pseudomonas aeruginosa. The method used was the disc diffusion method. The ethanol extract of black cumin seeds gain by maceration method and was made into various concentration (5, 7.5, 10, 12.5, and 15)%. For positive control, ciprofloxacin disc were used and negative control used distilled water. The research model used was in vitro experimental research. The results showed that ethanol extract of black cumin seeds have antibacterial activity against Klebsiella pneumoniae with inhibition zone diameters (4.5, 6.7, 10.1, 11, 12.8) mm, Pseudomonas aeruginosa with inhibition zone diameters (7.5, 12, 12.6, 13.4, 15.6) mm, positive controls respectively (24.3 and 20.7) mm and negative controls (0). It can be concluded that black cumin seed extract has an inhibiting effect on the growth of Klebsiella pneumoniae and Pseudomonas aeruginosa.

Background. The association between hypothyroidism and renal diseases has been described in many studies. Nigella Sativa was among the recently reported natural product that has the potential to prevent renal tissue damage and fibrosis. The aim of this study was to evaluate the possible protective effect of thymoquinone on the structure of the renal cortex of hypothyroid rats and explore the mechanism behind it. Methods. An experimental model of hypothyroidism was induced in adult male Wistar rats by administration of propylthiouracil (6 mg/kg/body weight). One hypothyroid group was treated with thymoquinone at the dose of 50 mg/kg/body weight and compared to the untreated group. Thyroid function and oxidant/antioxidant status were assessed in the serum. Catalase gene expression was assessed using the real-time polymerase chain reaction. The kidney was assessed both histologically and immunohistochemically. Results. Administration of propylthiouracil resulted in a significant decrease in the serum levels of nitric oxide, reduced glutathione, and superoxide dismutase activity while the level of malondialdehyde significantly (p<0.001) increased. Administration of thymoquinone alleviated this effect on the thyroid hormones and significantly increased the serum levels of antioxidants. Thymoquinone significantly (p<0.001) upregulated catalase transcription by about 24-fold and could block the hypothyroidism-induced glomerular and tubular injury. Conclusion. Thymoquinone may have a potential protective effect against hypothyroidism-induced renal injury acting through the attenuation of the oxidative stress and upregulation of renal catalase gene expression.

Multicultural Perspective

There is an emerging literature suggesting that speaking two or more languages may significantly delay the onset of dementia. Although the mechanisms are unknown, it has been suggested that these may involve cognitive reserve, a concept that has been associated with factors such as higher levels of education, occupational status, social networks, and physical exercise. In the case of bilingualism, cognitive reserve may involve reorganization and strengthening of neural networks that enhance executive control. We review evidence for protective effects of bilingualism from a multicultural perspective involving studies in Toronto and Montreal, Canada, and Hyderabad, India. Reports from Toronto and Hyderabad showed a significant effect of speaking two or more languages in delaying onset of Alzheimer’s disease by up to 5 years, whereas the Montreal study showed a significant protective effect of speaking at least four languages and a protective effect of speaking at least two languages in immigrants. Although there were differences in results across studies, a common theme was the significant effect of language use history as one of the factors in determining the onset of Alzheimer’s disease. Moreover, the Hyderabad study extended the findings to frontotemporal dementia and vascular dementia.

Abstract Background A formulation of black cumin (Nigella sativa L.), licorice (Glycyrrhiza glabra L.), anise (Pimpinella anisum L.) and tea (Camellia sinensis (L.) Kuntze) (denoted BLAB tea) is traditionally used to relief allergy reaction including allergic rhinitis. However, little is known about its underlining mechanism of anti-allergic effects. Methods To investigate the anti-allergenic mechanism of BLAB tea, we treated ovalbumin (OVA)-induced allergic rhinitis (AR) model of mice with BLAB tea, and elucidated its possible mechanism of action. Mice in the control group were treated with phosphate-buffered saline only. Subsequently, the infiltration of different inflammatory cells was measured. In addition, histopathological changes in the nasal mucosa, and the levels of allergen-specific cytokines and OVA-specific immunoglobulins were measured. Results The aqueous extract of BLAB significantly alleviated the nasal symptoms and reduced the accumulation of inflammatory cells in the nasal mucosa and nasal lavage fluid of AR model of mice. Conclusion The aqueous extract of BLAB induced the production of Th1 and Treg cytokines and inhibited the release of Th2 cytokines and histamine in nasal mucosa and serum of mice while decreasing the serum levels of OVA-specific IgE, IgG1, and IgG2a. These results suggest the potential of the aqueous extract of BLAB as a treatment option for allergic diseases.

Black Cumin

The prevalence of chronic kidney disease (CKD) is increasing worldwide, and a close association between acute kidney injury (AKI) and CKD has recently been identified. Black cumin (Nigella sativa) has been shown to be effective in treating various kidney diseases. Accumulating evidence shows that black cumin and its vital compound, thymoquinone (TQ), can protect against kidney injury caused by various xenobiotics, namely chemotherapeutic agents, heavy metals, pesticides, and other environmental chemicals. Black cumin can also protect the kidneys from ischemic shock. The mechanisms underlying the kidney protective potential of black cumin and TQ include antioxidation, anti-inflammation, anti-apoptosis, and antifibrosis which are manifested in their regulatory role in the antioxidant defense system, NF-κB signaling, caspase pathways, and TGF-β signaling. In clinical trials, black seed oil was shown to normalize blood and urine parameters and improve disease outcomes in advanced CKD patients. While black cumin and its products have shown promising kidney protective effects, information on nanoparticle-guided targeted delivery into kidney is still lacking. Moreover, the clinical evidence on this natural product is not sufficient to recommend it to CKD patients. This review provides insightful information on the pharmacological benefits of black cumin and TQ against kidney damage.
