ABSTRACT
@#【Objective】 A significant amount of evidence has lately revealed that individuals with nonalcoholic fatty liver diseases (NAFLD) are at high risk of cardiovascular diseases, which is the primary cause of death in patients. This study is to evaluate liver- and cardiovascular-protectant effects of Nigella sativa (N. sativa). 【Methods】 The meta-analysis was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature review was conducted in June 2022 with papers retrieved from the PubMed, ScienceDirect, and Cochrane Library websites from January 2010 to December 2021. The Review Manager version 5.3 was applied for the statistical analysis of parameters like aspartate transaminase (AST) and alanine transaminase (ALT) levels, lipid profil, blood glucose level, weight, and body mass index (BMI). 【Results】 The results showed that N. sativa could significantly decrease the AST (P = 0.009) and ALT (P < 0.05) levels in research subjects. Subjects in the N. sativa group had a significant higher cure rate of fatty liver than those in the placebo group (P = 0.000 1). In addition, lipid profile, blood pressure, and fasting blood glucose of subjects all significantly reduced in the N.sativa group (P < 0.05). However, the comparison of body weight and BMI between the N.sativa group and placebo group did not show significant difference (P > 0.05). 【Conclusion】 N. sativa did have certain liver-protectant and cardiovascular-protectant effects on patients with NAFLD or chronic liver diseases (CLD), despite the insignificant comparison of body weight and BMI between the N. sativa group and the placebo group.
ABSTRACT
Abstract Objectives: Nigella sativa oil is known antiallergic and immunomodulatory effects. We aimed to compare this oil with mometasone furoate, a topical steroid, on a rat model in the prevention of allergic rhinitis symptoms. Methods: A total of 28 two-to-four-month-old Wistar Hannover rats weighing 250-350 g were randomly divided into four groups of seven, which included control, allergic rhinitis, mometasone furoate, and Nigella sativa oil groups. Loss of cilia, an increase of goblet cells, vascular proliferation, inflammatory cell count, eosinophil infiltration, and the degree of hypertrophy in chondrocytes were assessed by light microscopy. Results: The frequency of nasal scratching in the Nigella sativa oil group was found to be significantly lower compared with the allergic rhinitis group (p < 0.05). Typical inflammatory changes seen in allergic rhinitis were not detected in the Nigella sativa oil group. No inflammation was observed in 85.7% of both the healthy control group and the Nigella sativa oil group. In addition, no inflammation was observed in 71.4% of the mometasone furoate group, and this difference was found to be significant compared with the control group (p < 0.05). In addition, eosinophil infiltration, cilia loss, chondrocyte hypertrophy, vascular proliferation, and goblet cell increase were found to be significantly decreased in the mometazone furoate and Nigella sativa oil groups compared to the allergic rhinitis group (p < 0.05). Conclusion: According to the findings obtained from this study, we found anti-inflammatory and anti-allergic effects of Nigella sativa oil as equally effective as mometasone furoate in the treatment of experimentaly generated allergic rhinitis. Level of evidence: IV.
ABSTRACT
The importance of Nigella sativa plant is increasing day by day in many medical and nutritional fields, and the demand for it is increasing in foreign markets. Therefore, we chose the nigella plant to study the effect of spraying with a natural growth stimulant (Ascobein) at concentrations of zero, 50, 100 and 150 ppm on the productivity of seed and oil, as well as its effect on the activity of antioxidants. The results showed that the concentration of 100 ppm gave the highest values of vegetative growth traits; (Plant height (86.3 and 89.5cm), Number of branches (21.7 and 25.1), Fresh and Dry weight per plant (118.43 and 143.85gm, 23.86 and 28.29gm/plant) respectively for both seasons. Also, results revealed that foliar application of 100 ppm (Ascobein) improved the seed yield/plant (16.95 and 19.74gm), Oil % (45.73 and 48.02%), DPPH% (99.04 and 102.39%), TPC (447.17 and 450.54 mg GAE/g) and TFC (110.19 and 114.43 mg QE/g) for both seasons 20/2021 and 21/2022. The percentage of major fatty acids in nigella seeds oil has been estimated (Linoleic, Oleic, Palmitic and Stearic).

Abstract Background Various studies are ongoing related to the radioprotective agents. Herbal preparations are currently becoming popular because of their beneficial effects with fewer side effects compared to the synthetic/semi-synthetic medicines, and Nigella sativa oil (NSO) is only one of them. Objective To investigate NSO for its antioxidant effects on the heart tissue of rats exposed to ionizing radiation (IR). Methods Thirty six male albino Wistar rats, divided into four groups, were designated to group I (IR plus NSO group) that received both 5 Gray of gamma IR to total cranium and NSO; group II (IR alone group) that received IR plus saline, group III (control group of NSO) that received saline and did not receive NSO or IR; group IV (control group) that received only sham IR. Alterations in Total antioxidant status (TAS) and Total oxidant status (TOS), Oxidative stres index (OSI), Sulhydryl group (SH), Lipid hydroperoxide (LOOH), Paraoxonase (PON) levels, Arylesterase (ARE) and Ceruloplasmin (CER) activities in homogenized heart tissue of rats were measured by biochemical methods. Results In heart tissue of the rats in the IR alone group (group II) LOOH, TOS and OSI levels were found to be higher, ARE activity and TAS level were found to be lower than all of the other groups (p < 0.01). These results also support that IR increases oxidative stress and NSO's protective effect. Conclusion NSO would reduce the oxidative damage in the irradiated heart tissue in the experimental rat model.

@#Introduction: Earlier attempts to stabilise an emulsion, intended for chronic periodontitis treatment which composed of doxycycline hyclate (DH), Nigella sativa oil (NSO), eugenol and several combinations of surfactants failed. To solve the issue, we investigated the ability of lecithin alone and its combination with hydroxypropyl methylcellulose (HPMC) to stabilise the emulsion. Method: Compatibility between DH and other ingredients was first investigated using DSC and ATR-IR. The emulsion was characterised, firstly by preparing three phases: doxycycline/preservatives with or without HPMC (varying quantities), NSO/eugenol and lecithin/surfactants as aqueous, oil and emulsifier phases, respectively. The phases were added and emulsified sequentially at 7000 rpm (10 min) with an overhead stirrer and then at 3000 rpm (15min) using a high-shear mixer. DH assay was performed using validated HPLC method. Results: All ingredients were found to be compatible with doxycycline based on DSC, ATR-IR and supported by acceptable recovery (98.2±2.2 %) of DH from the emulsion. Stable emulsions were produced with particle size of 198.6±8.2 to 279.3±10.7 nm and zeta potential of -48.2±0.4 to -64.0±3.9 mV. The emulsions showed high viscosity (~200 Pa.s) at zero shear rate and exhibited shear-thinning flow upon increased in shear stress yielding viscosity of ~3 Pa.s at 100 s-1 indicating pseudoplastic behaviour suitable for pre-filled syringe packaging intended for delivery into periodontal pocket. Conclusion: Lecithin is an excellent emulsifier that can also impart pseudoplasticity for a complex emulsion constitute of drug and natural oils. This could pave the way for a more complex emulsion formulation fusing contemporary and therapeutic oils
ABSTRACT
Medicinal plants have been used since ancient times as therapeutic agents for treatment of various diseases and ailments. Description of medicinal uses of plants are found abundantly in ancient papyrus writings from various civilizations. Indigenous cultures even today use herbs in their healing rituals. Medicinal plants are considered as rich sources of phytochemical ingredients which play a vital role for the development of new drugs.Nigella sativa (N. sativa) is commonly known as Black seed or Kalongi, sometimes also referred to as miracle herb has been studied extensively for its various medicinal benefits. Apart from being used as a spice it is also used in various traditional systems of medicine including Ayurveda due to its healing properties in the treatment of various diseases. The seeds of Nigella sativa and their oil have been widely used for centuries in the treatment of various ailments throughout the world. And it is an important drug in the Indian traditional system of medicine like Unani and Ayurveda. It has been extensively studied for its biological activities and therapeutic potential and has been shown to possess wide spectrum of activities like diuretic, antihypertensive, antidiabetic, anticancer, immunomodulatory, analgesic, antimicrobial, anthelmintic, analgesic, antiinflammatory, spasmolytic, bronchodilator, gastroprotective, hepatoprotective, renal protective and antioxidant properties. Most of the therapeutic properties of this plant are due to the presence of thymoquinone (TQ) which is a major active chemical component of the essential oil.Research into its therapeutic potential has highlighted its use due to its efficacy as an antioxidant, for glycaemic control, anticancer, antimicrobial and for its various other potential health benefits. Experimental studies have reported that Nigella sativa Oil and Nigella sativa extracts have anti-microbial activity against a wide range of microbes, especially multiple-antibiotic resistant bacteria. The current article tries to present a comprehensive and yet short review of this miraculous herb and its various applications in medicine especially in the backdrop of emerging antibiotic resistant superbugs.

ABSTRACT
Background: Nigella sativa (NS) has antioxidant and neuroprotective effects. Its concurrent use with AEDs couldbe a promising health strategy to prevent the damaging effect on neuronal cells during the episodes of seizures inaddition to enhancing therapeutic effects and diminishing the adverse drug reactions of AEDs. Purpose: Toprovide the pragmatic perception of utilizing TQ as an adjuvant in antiepileptic therapies to potentiate theiractions. Methods: The study utilizes systematic reviews on publications of previous studies obtained fromscholarly journal databases including PubMed, Medline, Ebsco Host, Google Scholar, and Cochrane. The studyutilizes secondary information obtained from health organizations using filters and keywords to sustaininformation relevancy. The use of search keywords and filters limits the study to relevant peer-reviewed journals.The study utilizes information retrieved from in vivo, in vitro and clinical studies captured in the peer-reviewedjournals on “thymoquinone and epilepsy”, “thymoquinone and neuroprotection” “Nigella Sativa and epilepsy,“thymoquinone and AEDs” “model of epilepsy and thymoquinone”. Results: TQ was demonstrated to inhibitapoptosis and neuronal degeneration in the cerebral cortex. Furthermore, Nigella sativa oil and its activeingredient TQ protects brain tissue against radiation-induced nitrosative stress, TQ plays a crucial protectiveactivity in the rat hippocampus and cortical neurons against Aββ1-42 and thus, it may be a promising agent forthe treatment of Alzheimer’s disease. An interesting series of studies also reported that TQ has shown antiepilepticeffects. Akhondian et al. reported that orally administered TQ reduces intractable pediatric seizures. Also,Hosseinzadeh et al., showed that TQ administered intracerebroventricularly, for epileptiform activity induced byusing pentylenetetrazole (PTZ) in rats, prolonged the latency to first seizure, and decreased seizure count and theperiods of tonic-clonic seizure in a dose-dependent manner. In another study, orally administered TQ prolongedthe first seizure latency, decreased seizure count, and eliminated lethality in PTZ-induced epilepsy. TQ has aprotective and inhibitory effect on a penicillin epilepsy model, as with the other experimental epilepsy models.Conclusion: The current approach to AED discovery is effective for identifying drugs that are useful for thesymptomatic treatment of seizures. However, such an approach cannot be adequate to develop therapies forpreventing and modifying the development of epilepsy in a susceptible person. Undoubtedly, TQ is demonstratedas an ideal adjuvant to antiepileptic therapies by potentiating their actions and retreating their adverse effects.
ABSTRACT
Metformin is a biguanide oral hypoglycemic drug used primarily in the treatment of DM. Nigella sativa (Activeingredient, Thymoquinone) has been found effective in lowering serum glucose levels and has protective effectspreventing the complications of Diabetes Mellitus. Diabetes Mellitus causes several complications, affectingalmost every organ of the body. The objective of this study was to investigate the effects of DM on liver, heartand kidney and to observe the protective as well as curative effects of Metformin and Nigella sativa from thosecomplications. The results obtained indicate that DM causes inflammation in liver and kidney and also leads tohydropic changes. While no significant changes could be observed in the heart during the study, it was observedthat Both Nigella sativa and Metformin decrease the early inflammatory changes caused by STZ induced DM inthe rat liver and kidneys but the hydropic changes continue.
ABSTRACT

Methods: Anti-microsporidial effect of thymoquinone against Encephalitozoon intestinalis was evaluated by using various concentrations of thymoquinone (0, 1, 5, 10, 15, 20, 30, 35, and 40 uM) and sterile dimethyl sulfoxide. Real time PCR was used to evaluate the inhibitory effects of thymoquinone on the life cycle of Encephalitozoon intestinalis. Results: The cytotoxic effect of thymoquinone on HEK293 cell line was observed with 30, 35, and 40 uM concentrations of thymoquinone after 24, 48, and 72 hours of incubation. It was observed that 10, 15, 20, and 30 uM concentrations of thymoquinone decreased the spore density compared with the control; however, it was significant only at 30 uM. Conclusions: Thymoquinone shows potent anti-microsporidial effects against Encephalitozoon intestinalis in the in vitro model; however, the toxic concentrations of thymoquinone are also toxic to the host cells.
ABSTRACT
OBJECTIVE@#The present work tested organic solvents to prepare an extract with anticancer properties from a polyherbal mixture containing Nigella sativa (seeds), Hemidesmus indicus (roots) and Smilax glabra (rhizomes). We evaluate anticancer effects in non-small-cell lung cancer cells (NCI-H292), and discuss optimization for pharmaceutical use in the context of efficacy, yield and toxicity.@*METHODS@#Using different organic solvents, six extracts were prepared from the polyherbal mixture. Based on the cytotoxic effects of these extracts on NCI-H292 cells and normal lung cells (MRC-5), as evaluated by the sulphorhodamine B assay, the total ethyl acetate (T-EA) extract was selected for further analysis. The possible anticancer mechanisms were assessed by evaluating the extract's effects on apoptosis (through fluorescent microscopic analysis, DNA fragmentation analysis, caspase 3/7 assay and analysis of expression levels of apoptosis-related genes p53, Bax, survivin, Hsp70 and Hsp90), colony formation and antioxidant activity.@*RESULTS@#The extract had cytotoxic effects against NCI-H292 cells in a time- and dose-dependent manner. Significant antioxidant activity and inhibition of colony formation were also observed. The expression level of caspase 3/7 significantly (P < 0.001) increased in NCI-H292 cells treated with 50 μg/mL of the extract. The same dosage led to a significant increase in expression levels of Bax and p53 (P < 0.05 and P < 0.01 respectively), accompanied by a significant decrease (P < 0.0001) in survivin, Hsp70 and Hsp90.@*CONCLUSION@#T-EA extract of the above polyherbal mixture has cytotoxicity against NCI-H292 cells via induction of apoptosis, antioxidant effects and inhibition of colony formation.

ABSTRACT
Background: Excessive oxidative stress on fracture case can inhibit fracture healing and decrease time of bone healing. Thymoquinone, an active substance of Nigella sativa, the so-called black cumin in common, is a potent antioxidant and have been studied as an antiosteoporotic agent. Thymoquinone is expected to be the adjuvant alternative that enhance the recovery process of fracture cases by reducing oxidative stress and promotes osteoblast proliferation on callus formation.Methods: Among 32 male mice Wistar Strain divided into 2 groups, conducted tibia fracture and casted. Group 1 was the control group without supplementation of Nigella sativa while black-cummin extract were given in group 2 orally at a dose of 800 mg/kg for 14 days. On the 14th day, group 1 and 2 were sacrificed, each bone tissue was taken to measure the levels of MDA by utilizing TBARS method and calculate the number of osteoblasts under the microscope. Data analysis were done using independent t-test.Results: There are both decreased MDA levels and increased number of osteoblasts that are histologically significant to the groups administered by Nigella sativa extract containing Thymoquinone compared to the control groups (p <0.05) on day 14.Conclusions: The administration of Thymoquinone from the extract of Nigella sativa reduced oxidative stress in fractures as well as increase the number of the osteoblast and its differentiation in callus formation.

ABSTRACT
Aim: The study investigated the effect of aqueous extract of Piper guineense and Nigella sativa on Testosterone, Estrogen and Follicle stimulating hormone levels in male and female rats induced by diets supplemented with high dose of sucrose and margarine for four (4) week. Materials and Methods: Thirty male and female Wistar rats of average weight (100 g) were used for the study. The rats were arranged into five groups with six rats in each of the groups. The rats had access to their normal feed but sucrose and margarine were used to induce hyperglycemia and hyperlipidemia respectively on the rats with the exception of the rats in the positive control group. The rats in the negative control were induced using the sucrose and margarine but were not treated using the aqueous extracts. The rats in the Piper guineense group were treated with 2 ml of Piper guineense aqueous leaf extract, while the rats in the Nigella sativa group were treated with 2 ml of Nigella sativa aqueous extract. The rats in the Nigella sativa and Piper guineense group were treated with 2 ml of the combined aqueous extract. Results: The results showed that the extracts had an increasing effect which was time dependent on the hormones. The highest increase was obtained on the third week of feeding when compared to the control. The testosterone levels (mlU/ml) showed for the, positive control (2.28 ± 0.08), uziza leaf (6.45 ± 0.01), black seed (2.85 ± 0.01), black seed &uziza (8.47 ± 0.08)(p<0.05). The increase for estrogen levels (mlU/ml) showed for the positive control (99 ± 0.82), uziza leaf (98 ± 1.63), black seed (100 ± 1.63), black seed & uziza (113 ± 0.82). Furthermore, the extracts also had an increasing effect on the follicle stimulating hormone levels with the highest increase obtained on the third week (p>0.05). The FSH levels (mlU/ml)) showed for the positive control (0.23 ± 0.01), uziza leaf 0.25 ± 0.01), black seed (0.54 ± 0.02), black seed & uziza (0.58 ± 0.01)(p<0.05). Histopathological findings also suggest that treatment with the aqueous extracts of P.guineense and N .sativa after inducement salvaged the testes and ovaries when compared to the induced group after the second week of administration. Although the combined mixture N.sativa and P.guineense extract was more effective. Conclusion: The results of the study indicate that the aqueous extract of a combined mixture of Nigella sativa and Piper guineense might be an effective plant in indigenous medicine, which may be used to combat infertility caused by hormonal imbalance.
ABSTRACT
Abstract Cystic echinococcosis (CE) are commonly found in the liver and lungs of affected hosts. The treatment approach is usually surgical, or giving drugs in conjunction before surgery to kill protoscolices, to avoid anaphylactic shock from leakage of hydatid fluid into the peritoneum and to decrease opportunities for recurrences. The present study was to evaluate the in vitro scolicidal efficacy of hydroalcoholic extract of Punica granatum peel and Nigella sativa, on the protoscolices of CE that collected from the lungs of infected camels. Different concentrations of extracts with different exposure times were used and a viability assay was applied to measure the scolicidal effect. N. sativa showed its highest scolicidal efficacy at 100 mg/mL and 10 mg/mL concentrations after 30 and 60 min. P. granatum peel extract showed its maximum scolicidal efficacy at 100 mg/mL concentration after 120 min. All experiments of the current study revealed that the extracts of both N. sativa and P. granatum had a scolicidal effects on the protoscolices of camel hydatid cysts. It could be concluded that N. sativa extract is more potent than P. granatum peel extract regarding scolicidal effect, but the efficacies of both extracts were of moderate significant correlation to exposure time and concentrations.
Resumo Os cistos hidáticos (equinococose cística, CE) são comumente encontrados no fígado e nos pulmões dos hospedeiros afetados. A abordagem do tratamento geralmente é cirúrgica, e algumas drogas são administradas em conjunto antes da cirurgia para matar protoscólices e evitar choque anafilático devido ao vazamento de fluido hidático no peritônio e diminuir as oportunidades de recorrência. O presente estudo foi avaliar a eficácia in-vitro do extrato hidroalcoólico de casca de Punica granatum e Nigella sativa, sobre os protoescólices de cistos hidáticos, que foram coletados dos pulmões de camelos infectados. Concentrações dos extratos com diferentes tempos de exposição foram utilizados e um ensaio de viabilidade foi aplicado para medir o efeito escolicida. A N. sativa apresentou sua maior eficácia escolicida nas concentrações de 100 mg/mL e 10 mg/mL após 30 e 60 min. O extrato de casca de P. granatum mostrou sua máxima eficácia escolicida na concentração de 100 mg/mL após 120 min. Todos os experimentos do presente estudo revelaram que os extratos de N. sativa e P. granatum tiveram efeito escolicida dependente da dose e do tempo nos protoescólices dos cistos hidáticos de camelo. Pode-se concluir que o extrato de N. sativa é mais potente que o extrato de casca de P. granatum em relação ao efeito escolicida, mas a eficácia de ambos os extratos foi de correlação significativa moderada com o tempo de exposição e as concentrações.

Nigella sativa, Allium sativum and Trigonella foenum-graecum are common dietary spices also traditionally used in the treatment of various diseases including diabetes mellitus. Clinical research has confirmed the efficacy of several spices extract in the modulation of oxidative stress associated with diabetes mellitus (DM). The therapeutic activity of each individual spice is well documented, but their effect when combined is unknown. Polyherbalism is of current interest because polyherbal formulations enhance therapeutic action and reduce the concentrations of single herbs, thereby reducing adverse events. This study evaluated the hypoglycaemic and anti oxidative activity of aqueous extract of black cumin, garlic, fenugreek individual and its combination at different doses in STZ-NT-induced diabetic rats. Diabetic rats were treated with aqueous extract for 30 days. These extract significantly (p<0.05) lowered the elevated fasting blood glucose, oxidative parameters but no effect seen in haematological indices. This oxidative stress was related to a decreased superoxide dismutase activity in diabetic rats. We suggested that black cumin, garlic, fenugreek and its combination could be used as antidiabetic complement in case of Type II diabetes mellitus.
