ABSTRACT
BACKGROUND: Lepidium sativum (LS) seed extract has various pharmacological properties, such as antioxidant, hepatoprotective, and anticancer activities. However, the translation of L. sativum seed extract to the clinical phase is still tedious due to its bioavailability and stability issues. This problem can be solved by encapsulating it in a nanodelivery system to improve its therapeutic potency. METHODS: In this study, we have determined and compared the in vivo toxicity of ethanolic extracts of L. sativum seeds (EELS) and solid lipid nanoparticles (SLNs). To conduct toxicity (acute and subacute toxicity) assessments, EELS and SLNs were orally administered to Swiss albino mice. Animal survival, body weight, the weight of vital organs in relation to body weight, haematological profile, biochemistry profile, and histopathological alterations were examined. RESULTS: Animals administered with 2000 mg/kg and 5000 mg/kg in an acute toxicity study exhibited no toxicological symptoms regarding behaviour, gross pathology, and body weight. As per a study on acute toxicity, the LD50 (lethal dose) for SLNs and EELS was over 400 mg/kg and over 5000 mg/kg, respectively. When animals were given SLNs (50 and 100 mg/kg, orally) and EELS (250, 500, and 1000 mg/kg, orally) for 28 days, subacute toxicity study did not exhibit any clinical changes. There were no differences in weight gain, haematological parameters, or biochemical parameters compared to the control groups (p > 0.05). The organs of the treated animals showed no abnormalities in the histological analysis (liver, heart, kidney, and spleen). CONCLUSION: The result confirms ethanolic extracts of L. sativum seeds and their SLNs to not have harmful effects following acute and subacute administration to mice. For further studies, patents available on Lepidium may be referred for its preclinical and clinical applications.

Acrylamide (ACR), an industrial compound, causes both male and female reproductive toxicity. Lepidium sativum seeds (L. sativum) (Garden cress) are known for their health benefits as antioxidant, antiasthmatic, anticoagulant, anti-inflammatory, and analgesic agents. Therefore, this study aimed to investigate the phytochemistry and nutritional value of L. sativum seeds oil for attenuating the ovarian damage induced by acrylamide in rats. The phytochemical investigation of the seeds revealed the presence of vitamins, potassium, iron, sugar and amino acids. Twenty eight compounds from the unsaponifiable fraction and twenty three compounds from the saponifiable fraction were identified. Three sterols and two triterpenes were isolated and identified as ß-sitosterol (1), âµ5-avenasterol (2), friedelanol (3), stigmasta-4, 22-dien-3-one (4), and ursolic acid (5). Treatment of acrylamide-induced rats with L. sativum seeds oil ameliorated prolactin (PRL), progesterone (P4), estradiol (E2), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), nitric oxide (NO), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF- α) with variable degrees. The histopathological findings of ovaries supported these results. In conclusion, compounds (3-5) were isolated for the first time from L. sativum seeds oil. The seeds oil attenuated the ovarian damage and could potentially be a new supplemental agent against female infertility.

Degradation of water quality is an emerging issue in many developing countries. In this context, industrial and domestic effluents heavily contaminate the coast of Moknine Continental Sebkha in Tunisia. The present study aimed to biomonitor the seawater quality of the Moknine Continental Sebkha coast using physicochemical and ecotoxicological approaches. The ecotoxicological assessment was performed using three species representing different trophic levels, namely Vibrio fischeri, Selenastrum capricornutum, and Lepidium sativum. In the physicochemical analysis such as BOD (biochemical oxygen demand), COD (chemical oxygen demand), TSS (total suspended solids), TOC (total organic carbon), NO3- (nitrate), AOX (adsorbable organic halogen), the recorded levels of pH and total suspended solids did not comply with the Tunisian standard (NT.09.11/1983). The ecotoxicological data confirmed that the tested water samples displayed toxicity to two test indicators L. sativum and S. capricornutum. A targeted chemical screening of the Moknine Continental Sebkha coast previously performed revealed the presence of total mercury, four phthalate acid esters, and one non-phthalate plasticizer, a fact that could explain the observed ecotoxicological effects and therefore might harm the biotic area and the health of the surrounding population.

This study addresses the growing interest in bio-based active food packaging by infusing Lepidium sativum (Garden cress) seeds extract (GRCE) into sodium alginate (SALG) films at varying concentrations (1, 3, and 5 %). The GRCE extract revealed six phenolic compounds, with gallic and chlorogenic acids being prominent, showcasing substantial total phenolic content (TPC) of 139.36 µg GAE/mg and total flavonoid content (TFC) of 26.46 µg RE/mg. The integration into SALG films significantly increased TPC, reaching 30.73 mg GAE/g in the film with 5 % GRCE. This enhancement extended to DPPH and ABTS activities, with notable rises to 66.47 and 70.12 %, respectively. Physical properties, including tensile strength, thickness, solubility, and moisture content, were positively affected. A reduction in water vapor permeability (WVP) was reported in the film enriched with 5 % GRCE (1.389 × 10-10 g H2O/m s p.a.). FT-IR analysis revealed bands indicating GRCE's physical interaction with the SALG matrix, with thermal stability of the films decreasing upon GRCE integration. SALG/GRCE5 effectively lowered the peroxide value (PV) of sunflower oil after four weeks at 50 °C compared to the control, with direct film-oil contact enhancing this reduction. Similar trends were observed in the K232 and K270 values.

An environmental toxicological assessment of fourteen furanic compounds serving as valuable building blocks produced from biomass was performed. The molecules selected included well studied compounds serving as control examples to compare the toxicity exerted against a variety of highly novel furans which have been additionally targeted as potential or current alternatives to biofuels, building blocks and polymer monomers. The impact of the furan platform chemicals targeted on widely applied ecotoxicity model organisms was determined employing the marine bioluminescent bacterium Aliivibrio fischeri and the freshwater green microalgae Raphidocelis subcapitata, while their ecotoxicity effects on plants were assessed using dicotyledonous plants Sinapis alba and Lepidium sativum. Regarding the specific endpoints evaluated, the furans tested were slightly toxic or practically nontoxic for A. fischeri following 5 and 15 min of exposure. Moreover, most of the building blocks did not affect the growth of L. sativum and S. alba at 150 mg L-1 for 72 h of exposure. Specifically, 9 and 11 out of the 14 furan platform chemicals tested were non-effective or stimulant for L. sativum and S. alba respectively. Given that furans comprise common inhibitors in biorefinery fermentations, the growth inhibition of the specific building blocks was studied using the industrial workhorse yeast Saccharomyces cerevisiae, demonstrating insignificant inhibition on eukaryotic cell growth following 6, 12 and 16 h of exposure at a concentration of 500 mg L-1. The study provides baseline information to unravel the ecotoxic effects and to confirm the green aspects of a range of versatile biobased platform molecules.

BACKGROUND: Hepatocyte death and a systemic inflammatory response are the outcome of a complex chain of events mediated by numerous inflammatory cells and chemical mediators. The point of this study was to find out if tadalafil and/or Lepidium sativum (L. sativum) could help people who have been exposed to carbon tetrachloride (CCL4) and are experiencing acute moderate liver failure. This was especially true when the two were used together. METHOD AND MATERIALS: To cause mild liver failure 24 h before sacrifice, a single oral dosage of CCL4 (2.5 mL/kg b.w.) (50% in olive oil) was utilized. Furthermore, immunohistochemical expression of nuclear factor kappa B (NF-κB) as well as histological abnormalities were performed on liver tissue. RESULTS: The results showed that tadalafil and/or L. sativum, especially in combination, performed well to cure acute mild liver failure caused by CCL4. This was demonstrated by a decrease in NF-κB expression in the liver tissue and an improvement in organ damage markers observed in the blood and liver tissues. Furthermore, such therapy reduced interleukin1 beta (IL-1ß) and tumor necrosis factor-alpha (TNF-α) levels in the liver tissue. It's worth noting that the tested combination resulted in greater liver improvement. CONCLUSIONS: According to the findings, tadalafil and L. sativum, particularly in combination, have the ability to protect the liver from the negative effects of CCL4 exposure. Because of its capacity to improve liver function, restore redox equilibrium, and decrease inflammatory mediators, it is a prospective option for mitigating the negative effects of common environmental pollutants such as CCL4.

The paper presents the results of studies on the influence of selected concentrations (10-100 mg L-1) of heavy metals (Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Zn) and metalloids (As, Sb, Se) on the germination and root elongation of garden cress (Lepidium sativum L). There are not many studies on phytotoxicity of heavy metals and metalloids with the complex use of single plant species so far. On the basis of the germination index (GI) and inhibition concentration IC50, the following order of phytotoxicity of the tested elements was determined: Se> As> Hg> Sb > Mo > Cd> Co > Zn > Ni. The other metals showed no phytotoxicity or even stimulating effect. In our study the stimulating effect of the majority of Pb concentrations and the lowest concentrations of Cd and Hg has been revealed. These metals do not play any role in living organisms, however some authors confirm their stimulating effect on plants at low concentrations. Toxic concentration of metals and metalloids calculated as IC50 are lower than the concentration calculated as GI (not phytotoxic). It is well known that seeds are more independent and tolerant to toxicants when they contain reserve substances which are used during the germination period. On the basis of conducted research, high tolerance of L. sativum to heavy metals and metalloids was found, which may indicate its usefulness for phytotoxicity assessment of leachate from contaminated soil or waste (e.g. foundry waste) and its application for bioremediation to manage heavy metal pollution of soils or foundry wastes containing heavy metals and metalloids. The understanding of heavy metal and metalloids toxicity will facilitate bioremediation.

AIM: The aim of the current study was to prepare a natural oral wound dressing from alginate modified with garden cress (GC), a rich source of antibacterial phytochemical compounds essential for wound healing. MATERIALS AND METHODS: Sodium alginate (SA) dressing (negative control group), was prepared and modified with GC seeds extracts (25 µg/mL and 50 µg/mL) as the intervention groups, and COE-PAK was the positive control group. Cytotoxicity was measured using WST-1 assay (n = 15) after 24 and 48 hours. The in vitro wound healing assay (n = 15) was assessed in terms of wound width, and cell migration rate (0, 24, 48, and 72 hours). Agar diffusion test was performed to investigate the antibacterial action (n = 15) of the groups against Streptococcus mutans and Lactobacillus casei strains. Results were significant at p ≤ 0.05. RESULTS: There was no statistically significant difference in cytotoxicity in all groups (p = 0.24 at 24 hours and 0.1 at 48 hours). Garden cress-containing groups revealed the lowest mean value of wound width (0.27 mm ± 0.01 and 0.23 mm ± 0.01 for 25 µg/mL and 50 µg/mL, respectively at 48 hours) and the highest mean value of cell migration rate (0.013 mm/hour ± 0.004 and 0.014 mm/hour ± 0.004 for 25 µg/mL and 50 µg/mL, respectively at 48 hours), in addition to the highest antibacterial action (1.49 mm ± 0.05 and 2.14 mm ± 0.09 for 25 µg/mL and 50 µg/mL, respectively against S. mutans, 1.43 mm ± 0.07 and 2.55 mm ± 0.09 for 25 µg/mL and 50 µg/mL, respectively against L. casei). CONCLUSION: Alginate wound dressing modified with GC extract could be considered a promising wound dressing material in terms of wound healing and antibacterial action. CLINICAL SIGNIFICANCE: Ready-to-use alginate-based wound dressing modified with GC extract may represent a promising natural alternative to the most commonly used oral wound dressing (COE-PAK).

Diabetes mellitus is a common serious metabolic illness occurring worldwide that may lead to male infertility. Various plants have been used in the treatment of diabetes. In this study, the effect of garden cress (Lepidium sativum) seed extract on fasting blood sugar is assessed for its protective effect on histopathological changes in the ventral prostate gland of streptozotocine-induced diabetic rats. Fifty adult male Wistar rats were randomly selected into five groups. Group 1 was the control placebo group where rats received only 0.1 mL normal saline via gastric gavages. Rats in Group 2 received an intraperitoneal injection of STZ 60 mg/kg body weight and those with FBS >250 mg/dL were considered diabetic. In Group 3, diabetic rats received insulin (3 U/100 g body weight) while in Groups 4 and 5 diabetic rats received 0.1 ml of 200 and 400 mg/kg respectively of an ethanol extract of Lepidium sativum seeds by gavage daily. The prostate was removed and weighed before transfer to Bouins solution for histological studies. Administration of the 200 and 400 mg/kg doses of Lepidium sativum seed extract increased epithelium height and decreased interstitial volume density and fibromuscular thickness of the prostate significantly. Also, the volume density of the epithelium, fibro muscular, lumen, and interstitial tissues were changed significantly. The results suggest that Lepidium sativum seed extract has beneficial effects as a protective agent against the detrimental effects of diabetes on the reproductive system of diabetic male rats.
La diabetes mellitus es una enfermedad metabólica común y grave que ocurre en todo el mundo y que puede conducir a la infertilidad masculina. Se han utilizado varias plantas en el tratamiento de la diabetes. En este estudio se evalúa el efecto del extracto de semilla de Lepidium sativum sobre los niveles de azúcar en sangre, en ayunas, por su efecto protector sobre los cambios histopatológicos en la próstata ventral, de ratas diabéticas inducidas por estreptozotocina (STZ). Cincuenta ratas Wistar adultas fueron divididas aleatoriamente en cinco grupos. El grupo 1 fue el grupo placebo, de control, en el que las ratas recibieron sólo 0,1 ml de solución salina normal mediante sondas gástricas. Las ratas del grupo 2 recibieron una inyección intraperitoneal de 60 mg / kg de peso corporal de STZ y aquellas con FBS> 250 mg / dl se consideraron diabéticas. En el grupo 3, las ratas diabéticas recibieron insulina (3 U / 100 g de peso corporal) mientras que en los grupos 4 y 5 las ratas diabéticas recibieron 0,1 ml de 200 y 400 mg / kg respectivamente de un extracto etanólico de semillas de Lepidium sativum por gavage diariamente. La próstata se retiró y se pesó antes de transferir a una solución de Bouin para realizar estudios histológicos. La administración de las dosis de 200 y 400 mg / kg de extracto de semilla de Lepidium sativum aumentó la altura del epitelio y disminuyó la densidad volumétrica intersticial y el espesor fibromuscular de la próstata, significativamente. Además, la densidad volumétrica del epitelio fibromuscular, del lumen y el intersticio de los tejidos sufrieron modificaciones significativas. Los resultados sugieren que el extracto de semilla de Lepidium sativum posee efectos beneficiosos como agente protector contra los efectos perjudiciales de la diabetes en el sistema reproductivo de las ratas macho diabéticas.

Diabetes mellitus is a frequent and serious metabolic illness all over the world and plants have been a desirable source of medicine recently. Diabetes has unpleasant effect on male reproductive system and it may lead to male infertility. It causes erectile dysfunction and reduces ejaculate volume by affecting the health of small blood vessels and the small nerves that control ejaculation and also decreases libido by decreasing testosterone levels. Current study evaluated the possible protective efficiency of Lepidium sativum (Garden cress) seed extract on fasting blood sugar (FBS) and then assessed histopathological change of epididymis in streptozotocine (STZ)-induced diabetic rats. We randomly categorized 50 adult male Wistar rats into five groups (each 10 rats). Group 1 was control placebo group receiving only 0.1 ml normal saline via gastric gavages, Group 2 as control diabetic rats received an intraperitoneal (IP) injection of STZ 60 mg/kg body weight. Rats with FBS >250 mg/dl were considered as diabetic. Group 3 were diabetic rats receiving insulin in dose 3U/100 g body weight and Groups 4 and 5 were diabetic rats that received 0.1 cc of 200 and 400 mg/kg, ethanol extract of Lepidium sativum seed by gavages daily. One day after the last gavages, rats were anesthetized by chloroform. Epididymis duct was removed from abdomen and weighed with a digital scale. Afterwards, samples were putted in Bouin's solution for histological measurement. Administration of 200 and 400 mg/ml doses of Lepidium sativum seed extract increased epithelium height and decreased interstitial volume density and fibro muscular thickness significantly. Also, volume density of epithelium, fibro muscular, lumen and interstitial decreased significantly. Tubular and lumen diameter did not change significantly in different groups. It appears Lepidium sativum seed extract is a beneficial protective supplementary agent against adverse effects of diabetes on male reproductive system.
La diabetes mellitus es una enfermedad metabólica frecuente y grave que afecta a los hombres en todo el mundo. Recientemente, las plantas han sido una fuente deseable de medicina para este tipo de enfermedad. La diabetes tiene un efecto perjudicial en el sistema reproductivo masculino y puede conducir a la infertilidad. Causa disfunción eréctil y reduce el volumen de la eyaculación al afectar los pequeños vasos sanguíneos y los nervios que controlan la eyaculación. También disminuye la libido reduciendo los niveles de testosterona. El presente estudio evaluó la posible eficacia protectora del extracto de semilla de Lepidium sativum en la glucemia en ayunas y también se evaluó el cambio histopatológico del epidídimo en ratas diabéticas inducidas por estreptozotocina (STZ). Se dividieron aleatoriamente 50 ratas Wistar macho adultas en cinco grupos de 10 ratas cada uno. El grupo 1 recibió 0,1 ml de solución salina normal a través de los gavajes gástricos, el grupo 2 de ratas diabéticas control recibió una inyección intraperitoneal (IP) de STZ 60 mg / kg de peso corporal. Las ratas con FBS> 250 mg / dl se consideraron como diabéticas. El Grupo 3 eran ratas diabéticas que recibieron insulina en dosis de 3 U/ 100 g de peso corporal y los Grupos 4 y 5 estaban compuestos por ratas diabéticas que recibieron 0,1 cc con 200 y 400 mg / kg, de extracto de etanol de semillas de Lepidium sativum por gavajes diarios. Un día después de los últimos gavages, las ratas fueron anestesiadas con cloroformo. Se extrajo el epidídimo y se pesó con una pesa digital. Posteriormente, las muestras se pusieron en solución de Bouin para el estudio histológico. La administración de dosis de 200 y 400 mg / ml de extracto de semilla Lepidium sativum aumentó la altura del epitelio y disminuyó significativamente la densidad volumétrica intersticial y el grosor fibromuscular. Además, la densidad volumétrica del epitelio fibromuscular, lumen e intersticio disminuyeron significativamente. El diámetro tubular y el lumen no cambiaron significativamente en los diferentes grupos. El extracto de semilla de Lepidium sativum es un agente complementario beneficioso protector contra los efectos adversos de la diabetes en el sistema reproductor masculino.

Purpose: The present study was undertaken to investigate diuretic effect of aqueous and methanol extracts of the dried seeds of Lepidium sativum in normal rats. Method: Aqueous and methanol extracts of L. sativum seeds were administered to experimental rats orally at doses of 50 and 100 mg/kg p.o. Hydrochlorothiazide (10 mg/kg) was used as positive control in study. The diuretic effect of the extracts was evaluated by measuring urine volume; sodium and potassium content; conductivity and pH. Result: Urine volume was significantly increased by the two doses of aqueous and methanol extracts in comparison to control group. While the excretion of sodium was also increased by both extracts; potassium excretion was only increased by the aqueous extract at a dose of 100 mg/kg. There was no significant change in the conductivity and pH of urine after administration of the L. sativum extracts. The diuretic effect of the extracts was comparable to that of the reference standard (hydrochlorothiazide) and the methanol had the additional advantage of a potassium-conserving effect. Conclusion: We can conclude that aqueous and methanol extracts of L. sativum produced notable diuretic effect which appeared to be comparable to that produced by the reference diuretic HCTZ. The present study provides a quantitative basis for explaining the folkloric use of L. sativum as a diuretic agent in Moroccan population
