Investigating the potential protective effects of natural product quercetin against imidacloprid-induced biochemical toxicity and DNA damage in adults rats. Toxicol Rep 2019; 6:727-735. [PMID: 31388500 PMCID: PMC6676460 DOI: 10.1016/j.toxrep.2019.07.007] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2018] [Revised: 07/03/2019] [Accepted: 07/19/2019] [Indexed: 12/22/2022] Open
Abstract
Imidacloprid insecticide causes hepatotoxicity, renal damage and DNA damage. Quercetin revealed a significant protective action against the toxic effects of Imidacloprid. Quercetin counteracts the imidacloprid effects on liver, Kidney and DNA damage to the normal level.
Quercetin (QT) is a natural antioxidant materials that’s possesses different type of pharmacological activities. In the current study, the protective effect QT against imidacloprid (IMD)-induced toxicity in rats was studied. The experiment included thirty-six adult male rats groups treated with QT, IMD (two different doses), their combinations and control non-treated group for 21 consecutive days. Different biochemical analysis (serum liver and kidney enzymes level, cholesterol and Glucose levels) were evaluated. DNA damage using comet assay and histopathological examination of different body organs were also screened. Treatment with IMD increased ALT, AST, serum urea, creatinine, cholesterol and Glucose levels but decreased the levels of serum total protein, albumin and body weight with induction in triacylglycerol and cholesterol levels. Animals treated with QT prior to IMD administration showed normal enzymatic levels which indicating a protective effect of QT. In addition, QT protected the different body organs from the histological changes and DNA damages induced by IMD toxicity. The present results showed the protective effect of QT as a natural material against the IMD induced toxicity at different doses.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Butea monosperma belonging to family Fabaceae is used in the Indian traditional medicine (Ayurveda) for various ailments including abdominal tumors and possess anti-estrogenic activity. AIM OF THE STUDY The present study is aimed at investigating the chemo-preventive potential of Butea monosperma in breast cancer and elucidating it's mechanism of action by assessing its effect on key processes like apoptosis, angiogenesis and metastasis. METHODS Cytotoxic potential of methanol extract of Butea monosperma flower (MEBM) was tested in MCF-7 (estrogen receptor positive), MDA-MB-231 (triple negative) and MDA-MB-453 (HER2 positive) human breast cancer cells by MTT assay. Chemo-preventive potential was evaluated in-vivo in Methylnitrosourea (MNU) induced mammary cancer in nulliparous Sprague-Dawley rats. The mechanism for anticancer potential was screened by in-vitro studies involving Annexin V- FITC assay (apoptosis), Chick Chorioallantoic Membrane assay (angiogenesis) and Migration assay (metastasis). Statistical analysis was done by one way and two way ANOVA (for Growth Rate and feed consumption efficiency) followed by post hoc Bonferroni's test with P value < 0.05. RESULTS It is observed that the exposure of MEBM, at various concentrations and time intervals to different cell lines, resulted in decreased cell proliferation. The IC50 value of MCF-7 cells was found significantly less than that of MDA-MB-231 and MDA-MB-453 cells, which indicated that the extract of said medicinal plant were more potent inhibitors of estrogen positive breast cancer cells than other types of breast cancer cells in vitro. Corroborative evidences were acquired in MNU actuated mammary carcinogenesis where MEBM constricted tumor parameters, decreased expression of estrogen and progesterone, nucleic acid content and increased latency period. MEBM also induced apoptosis, inhibited angiogenesis and metastasis in-vitro. CONCLUSION Selective cytotoxic activity in MCF-7 estrogen positive breast cancer cells and inhibition of growth of mammary carcinoma in-vivo by methanol extract of Butea monosperma flowers (MEBM) suggests chemo-prevention through modulation of estrogen and progesterone receptor, apoptotic, anti-angiogenesis and anti-metastatic activity.

Abstract
In the present study, we evaluated the stress response in adult rats who were administered imidacloprid (IMI) orally in two doses (0.5 and 1.0mg/kg bw for 60days). It led to an alteration in the levels of cortisone and catecholamines and induced behavioral deficits, particularly in the animals exposed to the dose of 1.0mg/kg. IMI was further analyzed for the effect on glucose homeostasis in developing and adult rats at a dose of 1.0mg/kg bw where it elicited a hyperglycemic effect. Moreover, we observed an alteration in the mRNA levels of glucose transporters. Histopathological and immunohistochemical data displayed structural perturbations in pancreatic tissue with a decline in the expression of insulin and GLUT4, particularly in the developing rats. Collectively, IMI treatment resulted in stress represented by behavioral and biochemical changes, particularly at a dose of 1.0mg/kg bw. Moreover, IMI perturbed the glucose regulation through hyperglycemic activity in both developing and adult rats, an observation clearly evident in the developing rats.

Abstract
Imidacloprid is a neonicotinoid insecticide being used extensively for crop protection and pet flea control programmes. The effect of repeated oral administration of two doses of imidcloprid (1/10th and 1/50th of LD50 of imidacloprid) on liver of female albino rat was assessed. Histological examination of liver revealed that imidacloprid (1/10th of LD50) treatment resulted in dilations of central vein and sinusoids between hepatocytes however imidacloprid (1/50th of LD50) treatment did not induce histopathological changes in liver. Non significant decrease in alkaline phosphatase (AKP) activity was observed in imidacloprid treated rats. Liver aspartate aminotransferase level showed significant increase in higher dose of imidacloprid. Additionally, significant increases in plasma levels of aspatate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (AKP) were observed in the treated rats. The results suggest that the higher doses of imidacloprid at 1/10th of LD50 is hepatotoxic as compared to lower dose of 1/50th of LD50 of imidacloprid.

Abstract
OBJECTIVE To find out the anticancer effect of Indigofera aspalathoides (I. aspalathoides) on 20-methylcholanthrene induced fibrosarcoma in rats. METHODS Fibrosarcoma was induced in Wistar strain male albino rats by 20-methylcholanthrene. Intraperitoneous (i.p.) administration of 250 mg/kg body weight/day of aqueous extract of I. aspalathoides for 30 d effectively suppressed chemically induced tumors. Parameters such as body weight, liver and kidney weight, tumor weight, mean survival time, behavioral changes, blood glucose, blood glycogen and marker enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), acid phosphatase (ACP) and 5'-nucleiotidase (5'-NT) in serum, liver and kidney and lipid profiles such as total cholesterol, phospholipids, free fatty acids in liver and kidney of control and experimental animals were studied. RESULTS Fibrosarcoma bearing animals were ferocious and anxious. The mean survival time was found to increase after the treatment. The body weights were significantly decreased (P<0.001) in group II fibrosarcoma animals which steadily increased after the treatment with I. aspalathoides. The liver and kidney weights were significantly increased whereas the tumor weights decreased as compared to the weights in untreated fibrosarcoma bearing rats. The blood glucose and the liver and kidney glycogen levels were found to decrease significantly (P<0.001) in group II animals. Elevated activities of marker enzymes were observed in serum, liver and kidney of fibrosarcoma bearing Group II animals which were normalize after I. aspalathoides treatment. In the liver and kidney of Group II animals the total cholesterol increased whereas the phospholipids and free fatty acid levels decreased (P<0.001) which were normalized after treatment. CONCLUSIONS The treatment by I. aspalathoides on fibrosarcoma bearing rats has improved the levels of various parameters indicating its antiproliferative and anticancer activity.

Abstract
Herbal medicine and medical plants such as Ziziphus vulgaris L. are widely used for the treatment of diseases such as diabetes mellitus. We investigated the effects of water extracts of Ziziphus vulgaris L. fruit on serum glucose, triglycerides, LDL-cholesterol, HDL-cholesterol and activities of aminotransferase enzymes inreptozocin-induced diabetic adult male rats. Continuous supplementation of this water extract by gavage at doses of 0.25, 0.5, 1, 1.5 and 2 g/kg in 0.5 ml distilled water in diabetic rats resulted in a significant decrease of fasting blood glucose and LDL-cholesterol and triglyceride levels after 14 days. The levels of HDL-cholesterol and insulin, and activities of serum aminotransaminase enzymes, alanine aminotransferase and aspartate aminotransferase were not changed significantly in the extract-supplemented group compared to the control group.

Abstract
A novel phosphorothionate [2-butenoic acid-3-(diethoxy phosphinothioyl)-ethyl ester; RPR-V] synthesized at Indian Institute of Chemical Technology (Hyderabad, India) was studied using subchronic doses of 0.033 (low), 0.066 (medium), and 0.099 (high) mg kg(- 1) in male and female rats daily for 90 days. Continuous treatment with RPR-V caused significant (p < 0.05) decreases in body-weight gain, feed intake, hemoglobin (Hb), hematocrit (Hct), and total erythrocyte count (TEC), whereas total leukocyte count (TLC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were increased. Similarly, RPR-V caused significant elevation in serum clinical chemistry parameters calcium, phosphorus, creatinine, and chloride contents, whereas protein and glucose levels were depressed in both male and female treated rats after 45 and 90 days of treatment. These alterations were significant when compared with two-way ANOVA showing that these changes were dose- and time-dependent. The effects of low dose were generally not statistically significant, whereas medium and high doses caused significant effects. The changes in male rats were not significant when compared with female rats showing no sexual dimorphism by this compound. Recovery was observed after 28 days post-treatment (withdrawal study), indicating that the compound entered into the system was eliminated from the body, and the blood parameters were improved. Hematological and clinical chemistry parameters can be detected rapidly and hence can be used for prediction and diagnosis of pesticide toxicity. Alterations in these parameters show toxic stress in the treated animals especially on blood and blood-forming organs.

Abstract
The healing activity of malabaricone B and malabaricone C, the major antioxidant constituents of the spice Myristica malabarica against the indomethacin-induced gastric ulceration in mice has been studied. The histological indices revealed maximum ulceration on the 3rd day after indomethacin administration, which was effectively healed by malabaricone B, malabaricone C (each 10 mg/kg body weight/day) and omeprazole (3 mg/kg body weight/day) for 3 days. Compared to the untreated ulcerated mice, treatment with malabaricone B, malabaricone C and omeprazole reduced the ulcer indices by 60.3% (P<0.01), 88.4% and 86.1% respectively (P<0.001). All the test samples accelerated ulcer healing than observed in natural recovery even after 7 days. Stomach ulceration reduced the total antioxidant status of plasma by 41% (P<0.05), which was significantly increased by malabaricone B (36%, P<0.01), malabaricone C (61%, P<0.001) and omeprazole (53%, P<0.001). Compared to the ulcerated untreated mice, those treated with malabaricone B reduced the levels of thiobarbituric acid reactive substances and protein carbonyls by 17% and approximately 34% respectively (P<0.05), while malabaricone C and omeprazole reduced the parameters almost equally (approximately 30%, P<0.01, and approximately 40%, P<0.01 respectively). Likewise, all the test samples reduced the oxidation of protein and non-protein thiols significantly (P<0.05). The antioxidant activity of the test samples could partly account their healing capacities. However, the differential potency of them was explainable by considering their relative abilities to modulate mucin secretion, PGE(2) synthesis and expression of EGF receptor and COX isoforms, malabaricone C being most effective in controlling all these factors.

Abstract
The present study deals with two ethnobotanical surveys carried out in two different segments of the Brazilian population: the first among the Krahô Indians living in Tocantins State, a Cerrado region, and the second one among the descendants of former black slaves, the Quilombolas, living in Mato Grosso State. Both populations use plants which may have effects on the central nervous system (CNS) in their ritual healing ceremonies. Field work was performed during two years by one of the authors (E. Rodrigues) utilizing methods from botany and anthropology. Information was obtained on a total of 169 plants which were utilized in the preparation of 345 prescriptions for 68 ailments seemingly of the CNS, classified as tonics, analgesics, anorectics, hallucinogens, and anxiolytics. The taxonomic families of plants used, the more common therapeutic indications and types of healing rituals are discussed.

Abstract
The 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay of the ether, methanol, and aqueous extracts of the spice Myristica malabarica (rampatri) revealed the methanol extract to possess the best antioxidant activity. Column chromatography of the methanol extract led to the isolation of a new 2-acylresorcinol and four known diarylnonanoids of which the diarylnonanoid, malabaricone C, showed the maximum DPPH scavenging activity. Malabaricone C could prevent both Fe(II)- and 2,2'-azobis(2-amidinopropane)dihydrochloride-induced lipid peroxidation (LPO) of rat liver mitochondria more efficiently than curcumin. The anti-LPO activity of malabaricone C was attributed to its better radical scavenging and Fe(II) chelation capacities. The superior activity of malabaricone C was rationalized by a systematic structure-activity correlation of the results obtained with the structurally related diarylnonanoids and curcumin. Malabaricone C also prevented the gamma-ray-induced damage of pBR322 plasmid DNA in a concentration-dependent manner. The radioprotective activity was found to correlate with its (*)OH radical scavenging property, which matched well with that of d-mannitol.

This study focused on an ethnopharmacological survey among a group of Brazilian Quilombolas (descended from runaway slaves living in hideouts up-country) whose therapeutic practices involve a combination of healing ceremonies and prescription of medicinal plants consisting of the use of, at least, 48 plants with possible effect on the central nervous system (CNS), cited in 53 formulas prescribed for 17 therapeutic indications, the main ones being: to fortify the brain, for insomnia, as a sedative, for insanity, weight loss, and rejuvenation. The formulas consist of one to ten plants, and each plant may be recommended for up to seven different therapeutic indications, with evidence of non-specificity in the use of plants in this culture. Of these 48 plants, only 31 could be identified to the species level as belonging to 20 taxonomic families, with the Asteraceae, Malpighiaceae, Cyperaceae, and Myrtaceae as the most important families. Only eleven of these species have been previously studied and appear in scientific literature. Some of these plants are at present under study in the Department of Psychobiology of the Federal University of Sao Paulo.
