[PMID: 38633734 PMCID: PMC11022303 DOI: 10.1002/hsr2.2029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 09/07/2023] [Accepted: 03/18/2024] [Indexed: 04/19/2024] Open
Abstract
Background and Aim Due to the concern about the side effects of chemical drugs and their ineffectiveness, the use of natural compounds as alternatives or complementary therapies has received increasing attention. The purpose of this study was to investigate the effect of Nigella sativa oil on the outcome of missed abortion. Methods In this double-blind clinical trial, 70 nulliparous pregnant women referred to Hajar Hospital and Imam Ali clinics of Shahrekord and had missed abortion before the 12-week gestational age were selected and randomly divided into two interventions and control groups. The intervention group received 5 g of Nigella sativa oil alone daily for up to 3 days and the control group received a placebo. In case of nonresponse, 3 days after the last dose of medication or placebo, 800 μg of misoprostol (vaginal) were used. Data were analyzed by SPSS software. The chi-square test, Fisher's exact test, independent t-test and paired t-test were used for analytical statistics. Results According to the results, 18 cases (51.4%) in the intervention group and seven cases (20%) in the control group showed complete evacuation of uterine contents which had a significant difference (p < 0.05). The frequency of vagina physical examination and type of hemorrhage did not show any significant difference between the two groups before and after the intervention. After the intervention, human chorionic gonadotropin (HCG) was significantly decreased in the intervention group but did not change in the control group (p < 0.05). The frequency of adverse events in the intervention group was three (8.6%) and in the control group was one (2.9%) which had no significant difference. Conclusion Nigella sativa improves the outcome of missed abortion by reducing HCG and facilitating cervix dilatation and delivery of uterine contents.

Abstract
Antioxidants are compounds that inhibit the oxidation of other molecules and protect the body from the effects of free radicals, produced either by normal cell metabolism or as an effect of pollution and exposure to other external factors and are responsible for premature aging and play a role in cardiovascular disease. degenerative diseases such as cataracts, Alzheimer's disease, and cancer. While many antioxidants are found in nature, others are obtained in synthetic form and reduce oxidative stress in organisms. This review highlights the pharmacological relevance of antioxidants in fruits, plants, and other natural sources and their beneficial effect on human health through the analysis and in-depth discussion of studies that included phytochemistry and their pharmacological effects. The information obtained for this review was collected from several scientific databases (ScienceDirect, TRIP database, PubMed/Medline, Scopus, Web of Science), professional websites, and traditional medicine books. Current pharmacological studies and evidence have shown that the various natural antioxidants present in some fruits, seeds, foods, and natural products have different health-promoting effects. Adopting functional foods with high antioxidant potential will improve the effective and affordable management of free radical diseases while avoiding the toxicities and unwanted side effects caused by conventional medication.

Abstract
Objectives We sought to determine the effect of topical application of Nigella sativa (black seed) oil, on the primary dysmenorrhea intensity. Methods We conducted a randomized, double-blind clinical trial on 124 female students, 18–22 years old, living in the dormitories of Sabzevar Universities. After a primary assessment, participants were randomly divided into two groups. The first group rubbed two drops of N. sativa oil, and the second group rubbed liquid olive oil, as the placebo. Massage was performed on the fontanel lobe 3, at night, three days before menstruation, for eight consecutive days (about five days after menses). This procedure was repeated for three menstrual cycles. After three cycles, pain severity was measured by the visual analog scale. Data analysis was carried out using the Mann-Whitney U test and analysis of covariance (ANCOVA). Results This study was conducted on 124 female students. The mean age of students, mean age of first menarche, body mass index, and pain severity were not significantly different in the two groups (p > 0.050). No adverse effects were observed during the study. The results of ANCOVA showed that pain intensity in N. sativa oil group was significantly decreased compared to that of the placebo group (0.6 score; p < 0.050). Conclusions N. sativa could be a promising, safe, and easily available analgesic supplement in women suffering from primary dysmenorrhea.

Ameliorative effect of Nigella sativa oil and vitamin C on the thyroid gland and cerebellum of adult male albino rats exposed to Monosodium glutamate (histological, immunohistochemical and biochemical studies). Tissue Cell 2020; 66:101391. [PMID: 32933714 DOI: 10.1016/j.tice.2020.101391] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 05/28/2020] [Accepted: 05/29/2020] [Indexed: 02/06/2023]
Abstract
Monosodium glutamate (MSG) is a major taste enhancer that is used as a food additive. Vitamin C (Vit C) and Nigella sativa oil (NSO) are known for their potent antioxidant activities. OBJECTIVE This study investigates the adverse effect of MSG on the thyroid gland and cerebellum of adult male albino rats and the protection against MSG-mediated toxicity provided by Vit C and NSO. DESIGN Fifty rats were divided into five groups that were treated via oral gavage. Group I (control) rats received distilled water, Group II rats were treated with MSG (6 mg/gm body weight/day), Group III rats were treated with MSG and Vit C (100 mg/kg body weight /day), Group IV rats were treated with MSG and NSO (50 mg/kg body weight two times per week), and Group V rats were treated with MSG together with both Vit C and NSO with MSG. After 60 days of treatment, rats were euthanized and histological sections were prepared from the thyroid gland and the cerebellum for routine staining and immunohistochemical detection of glial fibrillar acidic protein (GFAP), Caspase-3 and proliferating cell nuclear antigen (PCNA), respectively. Cerebellar tissue was also evaluated to determine glutathione (GSH) and malondialdehyde (MDA) levels; GSH was also measured in thyroid tissue. Serum levels of fT3, fT4 and TSH (thyroid stimulating hormone) were also evaluated. RESULTS Microscopic examination of cerebellar tissues revealed significant cerebellar injury and cellular apoptosis among the rats in Group II. The thyroid glands of Group II rats were notable for degenerating follicles, loss of colloid, sloughed follicular cells and congested blood vessels. The cerebellar and thyroid tissues from rats in treatment Groups III, IV and V revealed significantly less pathology. Cerebellar and thyroid tissues from Group II rats that were treated with MSG alone revealed intense GFAP and caspase-3 (cerebellar) and PCNA (thyroid) immunoreactivity. Furthermore, cerebellar tissues from rats received MSG alone (Group II) were notable for decreased levels of GSH and increased levels of MDA; thyroid tissue from rats in Group II also demonstrated decreased levels of GSH. Likewise, serum fT3 and fT4 levels were significantly decreased, while serum TSH was significantly increased among rats in Group II. Combined administration of Vit C and NSO together with MSG (Group V) revealed some variations in oxidative parameters compared to those in the Group I control rats. CONCLUSIONS Oral intake of MSG resulted in degenerative changes in neurons and astrocytes in cerebellum and, also degeneration of the thyroid glands of albino rats. Concomitant administration of Vit C and NSO may limit MSG-induced damage to the cerebellum and thyroid glands and thereby provide significant protection against the oxidative damage induced by MSG.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nigella sativa (N. sativa) L. (Ranunculaceae), well known as black cumin, has been used as a herbal medicine that has a rich historical background. It has been traditionally and clinically used in the treatment of several diseases. Many reviews have investigated this valuable plant, but none of them focused on its clinical effects. Therefore, the aim of the present review is to provide a comprehensive report of clinical studies on N. sativa and some of its constituents. MATERIALS AND METHODS Studies on the clinical effects of N. sativa and its main constituent, thymoquinone, which were published between 1979 and 2015, were searched using various databases. RESULTS AND DISCUSSION During the last three decades, several in vivo and in vitro animal studies revealed the pharmacological properties of the plant, including its antioxidant, antibacterial, antiproliferative, proapoptotic, anti-inflammatory, and antiepileptic properties, and its effect on improvement in atherogenesis, endothelial dysfunction, glucose metabolism, lipid profile dysfunction, and prevention of hippocampus pyramidal cell loss. In clinical studies, antimicrobial, antioxidant, anti-inflammatory, antitumor, and antidiabetic properties as well as therapeutic effects on metabolic syndrome, and gastrointestinal, neuronal, cardiovascular, respiratory, urinary, and reproductive disorders were found in N. sativa and its constituents. CONCLUSION Extensive basic and clinical studies on N. sativa seed powder, oil, extracts (aqueous, ethanolic, and methanolic), and thymoquinone showed valuable therapeutic effects on different disorders with a wide range of safe doses. However, there were some confounding factors in the reviewed clinical trials, and a few of them presented data about the phytochemical composition of the plant. Therefore, a more standard clinical trial with N. sativa supplementation is needed for the plant to be used as an inexpensive potential biological adjuvant therapy.

Abstract
BACKGROUND Nigella sativa Linn. is well known seed in the Middle East, Asia, and the Far East as a natural remedy for many ailments and as a flavoring agent proclaimed medicinal usage dating back to the ancient Egyptians, Greeks, and Romans. An authentic saying of the Prophet Muhammad (Peace Be Upon Him) about black seed is also quoted in Al-Bukhari. OBJECTIVE This study was carried out to evaluate the antidepressant effect and isolate the potential antidepressant constituents of the polar extract of N. sativa seeds. MATERIALS AND METHODS The antidepressant effect was evaluated through the immobility duration in tail suspension and forced swim tests (FSTs). Albino mice were orally treated with N. sativa polar extract and its RP-18 column chromatography fractions (50 and 100 mg/kg,). RESULTS The polar extract and two of its sub-fractions were significantly able to decrease the immobility time of mice when subjected to both tail suspension and FSTs, the effects are comparable to standard drug (Sertraline, 5 mg/kg). However, these treatments did not affect the number of crossings and rearing in the open field test. Phytochemical investigation of the two active fractions led to the isolation of quercetin-3-O-α-L-rhamnopyranoside 1, quercetin-7-O-β-D-gluco- pyranoside 2, tauroside E 3, and sapindoside B as the potential antidepressant constituents. SUMMARY Phytochemical and biological evaluation the antidepressant constituents in Nigella sativa using the tail suspension and forced swim methods afforded the isolation and identification of quercetin-3-O-α-L rhamnopyranoside, quercetin-7-O-β-D gluco pyranoside, tauroside E, and sapindoside B as the potential antidepressant constituents in the polar extract of N. sativa. The isolated compounds were identified through extensive NMR analysis (1D, 2D, ESI MS). Abbreviations used: TST: Tail suspension test, FST: Forced swim test, OFT: An Open field test.

Abstract
Nigella sativa (N. sativa) (Family Ranunculaceae) is a widely used medicinal plant throughout the world. It is very popular in various traditional systems of medicine like Unani and Tibb, Ayurveda and Siddha. Seeds and oil have a long history of folklore usage in various systems of medicines and food. The seeds of N. sativa have been widely used in the treatment of different diseases and ailments. In Islamic literature, it is considered as one of the greatest forms of healing medicine. It has been recommended for using on regular basis in Tibb-e-Nabwi (Prophetic Medicine). It has been widely used as antihypertensive, liver tonics, diuretics, digestive, anti-diarrheal, appetite stimulant, analgesics, anti-bacterial and in skin disorders. Extensive studies on N. sativa have been carried out by various researchers and a wide spectrum of its pharmacological actions have been explored which may include antidiabetic, anticancer, immunomodulator, analgesic, antimicrobial, anti-inflammatory, spasmolytic, bronchodilator, hepato-protective, renal protective, gastro-protective, antioxidant properties, etc. Due to its miraculous power of healing, N. sativa has got the place among the top ranked evidence based herbal medicines. This is also revealed that most of the therapeutic properties of this plant are due to the presence of thymoquinone which is major bioactive component of the essential oil. The present review is an effort to provide a detailed survey of the literature on scientific researches of pharmacognostical characteristics, chemical composition and pharmacological activities of the seeds of this plant.

Abstract
Fourier transform infrared spectroscopy (FTIR) combined with multivariate calibration of partial least square (PLS) was developed and optimized for the analysis of Nigella seed oil (NSO) in binary and ternary mixtures with corn oil (CO) and soybean oil (SO). Based on PLS modeling performed, quantitative analysis of NSO in binary mixtures with CO carried out using the second derivative FTIR spectra at combined frequencies of 2977–3028, 1666–1739, and 740–1446 cm−1 revealed the highest value of coefficient of determination (R2, 0.9984) and the lowest value of root mean square error of calibration (RMSEC, 1.34% v/v). NSO in binary mixtures with SO is successfully determined at the combined frequencies of 2985–3024 and 752–1755 cm−1 using the first derivative FTIR spectra with R2 and RMSEC values of 0.9970 and 0.47% v/v, respectively. Meanwhile, the second derivative FTIR spectra at the combined frequencies of 2977–3028 cm−1, 1666–1739 cm−1, and 740–1446 cm−1 were selected for quantitative analysis of NSO in ternary mixture with CO and SO with R2 and RMSEC values of 0.9993 and 0.86% v/v, respectively. The results showed that FTIR spectrophotometry is an accurate technique for the quantitative analysis of NSO in binary and ternary mixtures with CO and SO.

Abstract
Black Cumin (Nigella sativa), which belongs to the botanical family of Ranunculaceae, commonly grows in Eastern Europe, the Middle East, and Western Asia. Its ripe fruit contains tiny black seeds, known as "Al-Habba Al-Sauda" and "Al-Habba Al-Barakah" in Arabic and black seed or black cumin in English. Seeds of Nigella sativa are frequently used in folk medicine in the Middle East and some Asian countries for the promotion of good health and the treatment of many ailments. However, data for the cardiovascular benefits of black cumin are not well-established. We reviewed the literature from 1960 to March 2012 by using the following key words: "Nigella sativa," "black seeds," and "thymoquinone." Herein, we discussed the most relevant articles to find out the role of Nigella sativa in the cardiovascular diseases spectrum especially when there is a paucity of information and need of further studies in human to establish the utility of Nigella sativa in cardiovascular system protection.

Abstract
Plants belonging to the Ranunculaceae family, and particularly their seeds, have been a hot research topic in numerous pharmacognosy laboratories.Nigella glanduliferaFreyn et Sint (NG) is one of the promising, but relatively insufficiently studied, plants from this family. In this review, we summarize the recently isolated chemical constituents from the seeds of this plant including alkaloids, flavonol glycosides, isobenzofuranone derivatives, saponins, terpenes, terpenoids, and fatty acids. We put also a spotlight on the recently studied therapeutic potentials of such amazing herb seeds as antidiabetes, melanogenesis inhibition, anticancer, anti-inflammatory, antithrombosis, and antiplatelet aggregation effects. Herein, we illustrate certain properties and potentials via selected examples, and thus we suggest more studies to confirm the therapeutic hypotheses, find out new compounds, and eventually to discover novel properties.

Abstract
Nigella sativa L. is used as a galactagogue in traditional medicine. Hence, the effects of aqueous and ethanolic extracts of N. sativa seeds on milk production in rats were evaluated. The measurement of milk production was by measuring pup weight during suckling period. The intraperitoneal LD(50) values of aqueous and ethanolic extracts of N. sativa were 4.23 and 4.9 g/kg, respectively. The aqueous (0.5 g/kg) and ethanolic extracts (1 g/kg) increased milk production significantly (p < 0.001), producing about 31.3% and 37.6% more milk than control, respectively. During the study period, the pups gained weight with the aqueous (0.5 g/kg, p < 0.01) and ethanolic extracts (1 g/kg, p < 0.05). It is concluded that aqueous and ethanolic extracts of N. sativa can stimulate milk production in rats.

Abstract
The activity of an aqueous extract of Prasaplai, a Thai traditional medicine, was studied on the isolated rat uterus in the oestrus stage. The results showed that the extract inhibited the contraction induced by a submaximal dose of acetylcholine (2.04×10(-4) mg mL(-1)), oxytocin (1.54×10(-4) mg mL(-1)) and prostaglandin E2 (PGE2) (6.00×10(-4) mg mL(-1)). The inhibition was concentration-dependent and reversible by tissue washing. The IC50 of Prasaplai extracts expressed as milligram of powdered preparation per millilitre of perfusion solution for acetylcholine, oxytocin and PGE2 were 11.70, 10.00 and 5.75 mg mL(-1), respectively. These data reveal that Prasaplai has an antispasmodic effect against uterine contraction by different mechanisms and corroborate the traditional use in the treatment of dysmenorrhoea. Oral administration of single dose of the water extract, calculated as powdered Prasaplai up to 20 g kg(-1) in rats, showed no sign and symptom of acute toxicity, and no rat died even at the maximum dose.

Abstract
OBJECTIVE The effects of the lyophilized seed extract of Nigella sativa and its active ingredient, thymoquinone, were studied on the isolated melanophores of the wall lizard to find the mechanism of skin darkening at the cellular level. METHODS The integumental melanophores of the wall lizard, Hemidactylus flaviviridis, were assayed using the mean melanophore size index and their responses were recorded in the presence of various concentrations of the plant extract, thymoquinone, specific antagonists and potentiator. KEY FINDINGS Significant skin darkening activity of the extract of N. sativa and thymoquinone was observed on the isolated melanophores of the wall lizard. The pigment cells responded by distinct dispersion leading to skin darkening. The effect was physiologically significant as re-immersion in physiological saline made the melanophores return to their normal intermediate state. These melanin dispersal effects were antagonized by atropine as well as hyoscine and were also found to be highly potentiated by neostigmine, an anticholinesterase agent. CONCLUSIONS These findings suggest that the extract of N. sativa, as well as its active principle, mimic the action of acetylcholine in melanin dispersion leading to skin darkening via stimulation of cholinergic receptors of muscarinic nature within the melanophores of wall lizard. This study opens new vistas for the use of N. sativa active ingredient, thymoquinone, as a novel melanogen for its clinical application in skin disorders such as hypopigmentation or vitiligo.

Abstract
Coinage of terms like nutraceuticals, functional, and pharma foods has diverted the attention of human beings to where they are seeking more natural cures. Though pharmaceutical drugs have been beneficial for human health and have cured various diseases but they also impart some side effects. Numerous plants have been tested for their therapeutic potential; Nigella sativa, commonly known as black cumin, is one of them. It possesses a nutritional dense profile as its fixed oil (lipid fraction), is rich in unsaturated fatty acids while essential oil contains thymoquinone and carvacrol as antioxidants. N. sativa seeds also contain proteins, alkaloids (nigellicines and nigelledine), and saponins (alpha-hederin) in substantial amounts. Recent pharmacological investigations suggested its potential role, especially for the amelioration of oxidative stress through free radical scavenging activity, the induction of apoptosis to cure various cancer lines, the reduction of blood glucose, and the prevention of complications from diabetes. It regulates hematological and serological aspects and can be effective in dyslipidemia and respiratory disorders. Moreover, its immunopotentiating and immunomodulating role brings balance in the immune system. Evidence is available supporting the utilization of Nigella sativa and its bioactive components in a daily diet for health improvement. This review is intended to focus on the composition of Nigella sativa and to elaborate its possible therapeutic roles as a functional food to prevent an array of maladies.

Abstract
Black seed (N. Sativa L) is an oriental spice of the family Ranunculaceae that has long been rationally used as a natural medicine for treatment of many acute as well as chronic conditions including cardiovascular disease and immunological disorders. It has been used in the treatment of diabetes, hypertension, and dermatological conditions. There have been very few studies on the effects of N. Sativa as a chemoprevention of chronic diseases as well as in cancer prevention and/or therapy. Oxidative stress is a condition that underlies many acute as well as chronic conditions. The combination and role of oxidative stress and antioxidants in vivo is still a matter of conjecture. Our objective for the present study was to expose MCF-7 breast cancer cells in vitro (as a chronic disease example) to aqueous and alcohol extracts and in combination with H[2]O[2] as an oxidative stressor. Measurement of cell survival under various concentrations and mixtures was conducted using standard cell culture techniques, exposure protocols in 96 well plates and Fluorospectrosphotometry. Following cellular growth to 90% confluencey, exposure to water (WE) and ethanol (AE) extracts of N. sativa and H[2]O[2] was performed. Cell survival indices were calculated from percent survival using regression analysis. Results showed that the alcohol extract and its mixtures were able to influence the survival of MCF-7 cells (indices ranged from 357.15- 809.50 mug/ml in descending potency for H[2]O[2]+AE to the mix of 3). In contrast, H[2]O[2] alone reduced effectively the survival of MCF-7 cells and the least effective combinations in descending potency were AE+H[2]O[2], WE+H[2]O[2], AE+WE, and WE+AE+H[2]O[2]. Mixtures other than AE+H[2]O[2] showed possible interactions and loss of potency. In conclusion, N. Sativa alone or in combination with oxidative stress was found to be effective (in vitro) in influencing the survival of MCF-7 breast cancer cells, unveiling promising opportunities in the field of cancer chemoprevention and/or treatment.

Abstract
Extracts obtained from the seeds of Nigella sativa are used as a spice or remedy for the treatment of various inflammatory diseases. The purpose of this study was to examine the analgesic and anti-inflammatory effects of its polyphenols. N. sativa seed polyphenols were prepared, and analgesic and anti-inflammatory effects were studied in mice and rats using the acetic acid-induced writhing, formalin, light tail flick, carrageenan-induced paw edema, and croton oil-induced ear edema tests. In the acetic acid-induced writhing test, oral administration of N. sativa polyphenols (NSP) decreased the number of abdominal constrictions. Both oral and intraperitoneal administration of NSP significantly suppressed in a dose-dependent manner the nociceptive response in the early and late phases of the formalin test, and the effect on the late phase was more pronounced. Pretreatment with naloxone failed to reverse the analgesic activity of NSP in this test. NSP did not produce a significant analgesia in the light tail flick test in mice. Oral administration of NSP did not produce a significant reduction in carrageenan-induced paw edema. However, when injected intraperitoneally, NSP inhibited paw edema in a dosedependent manner. NSP when applied topically failed to reduce croton oil-induced ear edema. These results suggest that NSP have analgesic and anti-inflammatory effects. The lack of analgesic effect of NSP in the light tail flick test and also the failure of naloxone to reverse the analgesia in the formalin test reveal that mechanisms other than stimulation of opioid receptors are involved.

Abstract
The science of life--Ayurveda is practiced in India since time immemorial. Besides being cheap and easily available Ayurvedic drugs are considered safe. Moreover, there is surge in the interest in Ayurveda due to quest of alternative medicines. Many of the gynecological disorders being not reported to the physicians, are treated with household remedies in India. The science of Ayurveda deals with these issues in a systematic manner as evident from the classification of diseases available and the number of plant drugs or the combinations thereof available for the treatment. In the present article, Ayurvedic herbal formulations and single plant drugs used traditionally in treatment of gynecological disorders are described.

Abstract
The steam-distilled essential oil of Iranian black cumin seed (Nigella sativa L.) was investigated for its composition and analgesic and antiinflammatory properties. After oil analysis by GC/MS, 20 compounds were identified in the oil, obtained in 0.4% (v/w) yield. Among them, para-cymene (37.3%) and thymoquinone (13.7%) were the major components. Acetic acid-induced writhing, formalin and light tail flick tests were used for assessment of analgesic activity. Antiinflammatory activity was evaluated using carrageenan-induced paw oedema in rats and croton oil-induced ear oedema in mice. Black cumin seed essential oil (BCSEO) was found to produce a significant analgesic effect in acetic acid-induced writhing, formalin and light tail flick tests. Naloxone, an opioid antagonist, could not reverse the analgesic effect observed in the formalin test. Although oral administration of BCSEO at doses of 100, 200 and 400 micro L/kg did not exert a significant antiinflammatory effect in the carrageenan test, i.p. injection of the same doses significantly (p < 0.001) inhibited carrageenan-induced paw oedema. BCSEO at doses of 10 and 20 micro L/ear could also reduce croton oil-induced oedema. It seems that mechanism(s) other than opioid receptors is (are) involved in the analgesic effect of BCSEO since naloxone could not reverse this effect. Both systemic and local administration of BCSEO showed antiinflammatory activity. Thymoquinone, as one of the major components of BCSEO, probably has an important role in these pharmacological effects.

Abstract
This experiment was carried out to investigate the effect of N. sativa L. on histopathology of pancreatic beta-cells, and blood insulin and glucose concentrations in streptozotocin-induced diabetic rats. Fifty male Wistar rats (200-250 g) were divided into two experimental groups (diabetics with no treatment and diabetics with N. sativa L. treatment), each containing twenty-five rats. Diabetes was induced in both groups by a single intraperitoneal injection of streptozotocin (STZ) (50 mg/kg). The experimental animals in both groups became diabetic within 24 hours after the administration of STZ. The rats in N. sativa L.-treated group were given the daily intraperitoneal injection of 0.20 ml/kg of N. sativa L. volatile oil for 30 days starting the day after STZ injection. Control rats received only the same amount of normal saline solution. The rats in both groups received the last injection 24 hours before the sacrification and 5 randomly-selected rats in each group were sacrificed before, and the 1, 10, 20 and 30 days after the STZ injection to collect blood and pancreatic tissue samples. The N. sativa L. treatment caused a decrease in the elevated serum glucose, an increase in the lowered serum insulin concentrations and partial regeneration/ proliferation of pancreatic beta-cells in STZ-induced diabetic rats with the elapse of the experiment. It is concluded that the hypoglycaemic action of N. sativa L. could be partly due to amelioration in the beta-cells of pancreatic islets causing an increase in insulin secretion. More studies are needed to demonstrate the exact mechanism of action of N. sativa L. on ameliorated blood glucose concentration in STZ-induced diabetes.

Abstract
The effect of an aqueous extract of Nigella sativa seeds was studied on candidiasis in mice. An intravenous inoculum of Candida albicans produced colonies of the organism in the liver, spleen and kidneys. Treatment of mice with the plant extract (6.6 mL/kg equivalent to 5 mg of estimated protein, once daily for 3 days) 24 h after the inoculation caused a considerable inhibitory effect on the growth of the organism in all organs studied. A 5-fold decrease in Candida in kidneys, 8-fold in liver and 11-fold in spleen was observed in the groups of animals post-treated with the plant extract. Histopathological examination of the respective organs confirmed these findings. These results indicate that the aqueous extract of Nigella sativa seeds exhibits inhibitory effect against candidiasis and this study validates the traditional use of the plant in fungal infections.

Abstract
The protective effect of Nigella sativa seed extract and its main constituents thymoquinone (TQ) was studied on mouse cells infected with schistosomiasis. Bone marrow cells in the in vivo experiments and spleen cells in the in vitro one were used to evaluate the potentially protective effect of these natural compounds on the induction of chromosomal aberrations. Karyotyping of the mice cells illustrated that the main abnormalities were gaps, fragments and deletions especially in chromosomes 2, 6 and some in chromosomes 13 and 14. Both N. sativa extract and TQ were considered as protective agents against the chromosomal aberrations induced as a result of schistosomiasis.

Abstract
This study was carried out to investigate whether Nigella sativa could decrease the lipid peroxidation, increase the anti-oxidant defence system and also prevent the lipid-peroxidation-induced liver damage in experimentally induced diabetic rabbits. Fifteen New Zealand male rabbits were divided into three experimental groups: control, diabetic and diabetic and N. sativa-treated. The diabetes mellitus (DMI) was induced in the rabbits using 150 mg/kg of 10% alloxan. The diabetic + N. sativa-treated group was given extract of N. sativa seeds orally every day for 2 months after induction of DM. At the end of the 2-month experiment, blood samples were collected to measure malondialdehyde (MDA), glutathione (GSH), ceruloplasmin and glucose concentration, and livers were harvested for histopathological analysis. Treatment with N. sativa decreased the elevated glucose and MDA concentrations, increased the lowered GSH and ceruloplasmin concentrations, and prevented lipid-peroxidation-induced liver damage in diabetic rabbits. It was concluded that N. sativa might be used in diabetic patients to prevent lipid peroxidation, increase anti-oxidant defence system activity and also prevent liver damage.

Abstract
The methanol soluble portion of black cumin oil, which is prepared by compression of seeds of Nigella sativa L., showed inhibitory effects on arachidonic acid (AA)-induced platelet aggregation and blood coagulation. By bioactive assay of AA-induced platelet aggregation, the methanol soluble part was purified to isolate a new compound 2-(2-methoxypropyl)-5-methyl-1,4-benzenediol (1) and two known compounds, thymol (2), carvacrol (3), having very strong inhibitory activity. Further, we then examined the isolated compounds (1-3) and eight related compounds by the screening test for AA-induced platelet aggregation. Compounds possessing aromatic hydroxyl and acetoxyl group had more potent activity than aspirin, which is well known as a remedy for thrombosis.

Abstract
The essential oil of black cumin seeds, Nigella sativa L., was tested for a possible antioxidant activity. A rapid evaluation for antioxidants, using two TLC screening methods, showed that thymoquinone and the components carvacrol, t-anethole and 4-terpineol demonstrated respectable radical scavenging property. These four constituents and the essential oil possessed variable antioxidant activity when tested in the diphenylpicrylhydracyl assay for non-specific hydrogen atom or electron donating activity. They were also effective.OH radical scavenging agents in the assay for non-enzymatic lipid peroxidation in liposomes and the deoxyribose degradation assay. GC-MS analysis of the essential oil obtained from six different samples of Nigella sativa seeds and from a commercial fixed oil showed that the qualitative composition of the volatile compounds was almost identical. Differences were mainly restricted to the quantitative composition.

Abstract
Whole Nigella sativa (N. sativa) proteins were purified on a DEAE Sephadex A50 ion exchange column. Complete fractionation was achieved in four peaks. Analysis of the purified peaks was carried out by sodium dodecyl sulphate polyacrylamide gel electrophoresis. Whole N. sativa showed a number of protein bands ranging from 94-10 kDa molecular mass. In mixed lymphocyte cultures (MLC), whole N. sativa and its purified proteins were found stimulatory as well as suppressive and this effect varied from one donor to another. Maximum stimulation (mean + S.E. of % relative index was 63.73 + 20.78) was observed with fractionated N. sativa proteins (P1) (10 microg/ml) in MLC. In MLC, also N. sativa peaks (P1 and P2) were stimulatory at all concentrations (10 microg/ml, 1 microg/ml or 0.1 microg/ml) used. However, a uniformly suppressive effect of N. sativa and its all four peaks at a concentration of 10 microg/ml was noticed when lymphocytes were activated with pokeweed mitogen (PWM). The effect of N. sativa proteins was further evaluated on the production of cytokines which were measured by using specific enzyme-linked immunosorbent assay. Large quantities of IL-1beta were secreted by whole N. sativa in culture medium with non-activated peripheral blood mononuclear cells (PBMC) (450 pg/ml) and with allogeneic cells (410 pg/ml). Fractionated N. sativa was less effective when compared with whole N. sativa proteins. No effect on IL-4 secretion was seen either by using non-activated, PWM-activated or allogeneic-cells. Whole N. sativa suppressed as well as stimulated the production of IL-8 in non-activated and PWM-activated PBMC respectively. All N. sativa peaks with protein concentration of 2 microg/ml were stimulatory for the induction of IL-8 by PWM-activated cells. However, no effect on IL-8 was seen either with whole N. sativa or its peaks when allogeneic PBMC were used. Stimulatory effect of whole N. sativa and fractionated proteins was also noticed on the production of TNF-alpha either using non-activated or mitogen activated cells.

Abstract
The black cumin or Nigella sativa L. seeds have many acclaimed medicinal properties such as bronchodilatory, hypotensive, antibacterial, antifungal, analgesic, anti-inflammatory and immunopotentiating and are universally accepted as a panacea. This review article has surveyed the relevant literature on Nigella sativa from 1960-1998 and examines the scientific evidence for these medicinal claims and highlights areas in need of research.
