Alternations of cardiac biomarkers in White Pekin ducks intoxicated with arsenic and its amelioration by use of ginger

Cardiotoxicity is an imperative issue in the assessment of heavy metal consumption and inorganic arsenic (As). These have a cardiotoxic effect which is evaluated by biochemical, and oxidative-antioxidant tests, and by the Nrf2- HO-1 pathway. Dried ginger powder is recognized for its efficient antioxidant activities and as a protector of the cardiovascular system from toxic damage caused by heavy metals. However, the possible function of ginger against As in heart via heme oxygenase-1 (HO-1) and nuclear factor erythroid 2-related factor (Nrf2) is unclear. A total of 120 White Pekin ducks were randomly distributed into groups comprising 24 birds in each. Each group comprised 3 replicates having 8 birds in each replicate. The time period of this study was 90 days. The groups were the control [Group I] whereas groups II to IV were fed a basal diet including arsenic at 28 mg/L. Dried ginger powder as an ameliorative agent was mixed with the basal diet and fed at 0.1, 0.3 and 1 g/kg feed to groups III, IV and V, respectively. In the current experiment, dried ginger powder decreased As-induced reactive oxygen species (ROSs) production, oxidative injury and pathological modifications. In addition, cardiac dysfunction factors, intracellular calcium (Ca2+), As accumulation and cAMP deficiency levels were noticed in ducks; these alternations were attenuated by ginger. Furthermore, ginger significantly altered the down regulation of both HO-1 and Nrf2 gene expressions caused by As. Thus, the proven protective role of ginger against As-induced cardiotoxicity may be a consequence of the maintenance of redox homeostasis, i.e. the Nrf2-HO-1 pathway and by enabling As efflux.

Evaluating nutritional values for lemongrass (Cymbopogon citratus) herb tea formulation used in tea bags

Tea is the second-most popular beverage engrossed after water. This study intends to formulate a herb tea using Cymbopogan citratus (lemongrass) in tea bags and evaluate its phytochemical and nutritional values. Lemongrass tea is abundant in energy, protein, carbohydrate fiber, and sodium. The method of making lemongrass tea is straightforward to prepare. It is prepared using lemongrass powder, mint leaf powder, dried ginger powder, and cardamom powder, then packed in the tea bag and dipped into hot water. Lemongrass tea boosts the immune system and detoxifies the body and it includes organic antioxidants and anti-inflammatory properties that can help prevent free radicals in the human body when consumed daily. Alkaloids, flavonoids, saponins, quinones, and tannins are among the active ingredients found in lemongrass plants. These chemicals provide antibacterial, antioxidant, pain relieving, cough and cold relief, stomach acid reduction, and aromatherapy effects due to their distinct and fresh aroma.

A Rapid Non-Destructive Hyperspectral Imaging Data Model for the Prediction of Pungent Constituents in Dried Ginger.

Ginger is best known for its aromatic odour, spicy flavour and health-benefiting properties. Its flavour is derived primarily from two compound classes (gingerols and shogaols), with the overall quality of the product depending on the interaction between these compounds. Consequently, a robust method for determining the ratio of these compounds would be beneficial for quality control purposes. This study investigated the feasibility of using hyperspectral imaging to rapidly determine the ratio of 6-gingerol to 6-shogoal in dried ginger powder. Furthermore, the performance of several pre-processing methods and two multivariate models was explored. The best-performing models used partial least squares regression (PSLR) and least absolute shrinkage and selection operator (LASSO), using multiplicative scatter correction (MSC) and second derivative Savitzky–Golay (2D-SG) pre-processing. Using the full range of wavelengths (~400–1000 nm), the performance was similar for PLSR (R2 ≥ 0.73, RMSE ≤ 0.29, and RPD ≥ 1.92) and LASSO models (R2 ≥ 0.73, RMSE ≤ 0.29, and RPD ≥ 1.94). These results suggest that hyperspectral imaging combined with chemometric modelling may potentially be used as a rapid, non-destructive method for the prediction of gingerol-to-shogaol ratios in powdered ginger samples.

Ameliorative property of ginger (Zingiber officinale) in minimising immunosuppression induced by arsenic in White Pekin ducks (Anas platyrhynchos)

Due to industrialisation heavy metal toxicity is increasing day by day. The current research was performed to reduce the immunosuppressive effects of arsenic (As) by supplementing ginger in basal diet. About 120 White Pekin ducks of 7 days old were randomly allocated into 5 groups having 24 birds in each. Each group contained 3 replicates having 8 birds in each replicate and fed either basal diet as such (control/ T1); T2: 28 ppm As/L of drinking water + basal feed; T3: 28 ppm As/L of drinking water + dried ginger powder @ 100 mg/kg of basal feed; T4: 28 ppm As/L of drinking water + dried ginger powder @ 300 mg/kg of basal feed; T5: 28 ppm As/L of drinking water + dried ginger powder @ 1 g/kg of basal feed for 90 days. The decreased in body weight and FCR in T2 was improved significantly in T4 and T5. Ginger enhanced the activity of anti-oxidative enzymes in spleen tissue of As intoxicated birds. Suppressed immunity due to As toxicity were attenuated by ginger supplementation through enhanced phagocytic activity, phagocytic index, humoral and cell mediated immunity. Similarly, serum corticosterone level was significantly reduced in ginger treated birds than As intoxicated ducks. Besides above facts there were also histopathological alternations of spleen. It was concluded that, As exerts immunosuppressive effects and supplementation of ginger at 1 g/kg diet was effective in enhancing immunity and protecting the ducks from oxidative stress induced by As.

Efficacy of Ginger on Male Reproductive Traits and Oxidative Stress Indices in White Pekin Ducks Intoxicated with Arsenic

Arsenic (As) exerts adverse effects on reproduction and oxidative stress in monogastric animals. But in poultry birds this fact is not yet verified. Ginger has both androgenic and antioxidant property. Thus, in this experiment, the protective effect of ginger against As toxicity induced by sodium arsenite was investigated in White Pekin ducks. For this, 300 number of ducks were randomly allocated into 5 groups with 6 replicates (10 ducklings in each replicate). The control group (CON) was fed only basal diet along with normal water. The toxicity group (TOX) was fed sodium meta-arsenite @ 28 ppm in drinking water along with basal feed. Along with sodium meta-arsenite @ 28 ppm in drinking water, the dried ginger powder was fed in increasing doses @ 100, 300 and 1000 mg per kg basal feed in ameliorative groups LDG, MDG and HDG respectively. Duration of experiment was 6 months. The oxidative damage caused by As was restored by supplementation of ginger. Ginger also enhanced the antioxidant activities of testis tissue of birds by suppressing reactive oxygen species (ROSs). Suppressed reproductive performance of male duck due to inorganic As toxicity were impaired by ginger through enhanced testicular size, semen volume, spermatozoa concentrations, live spermatozoa percentage and testosterone level. Histopathological examination of testis of As intoxicated birds showed significant changes which were restored by supplementation of ginger. In conclusion, adverse effects of As on reproductive performance of male duck was corrected by dried ginger supplementation.

Purpose: Ginger (Zingiber officinale) has been widely used as an antiemetic agent. This systematic review was aimed at evaluation of the effect of dried ginger powder supplementation on improvement of nausea and vomiting associated with early pregnancy or motion sickness. Methods: We searched Pubmed, Cochrane, Science Direct, and KISS (Korean studies Information Service System) using keywords such as ginger or Zingiber officinale in combination with nausea, vomiting, motion sickness, or pregnancy, published in March 2013. Results: The strength of the evidence was evaluated on the selected 12 RCTs (randomized controlled trials). Eleven trials including 2,630 subjects showed that supplementation with dried ginger powder resulted in significant improvement of nausea or vomiting related to early pregnancy or motion sickness. Among the nine studies including 809 women in early pregnancy before 20 weeks of gestation, ginger supplementation was superior to placebo in five studies (n = 305), and as effective as positive control (vitamin B 6 or dimenhydrinate) in four studies (n = 504). Ginger intake significantly reduced the episodes or severity of vomiting related to motion sickness compared to placebo or showed the same effect as several antiemetic drugs in two studies (n = 1,821). Conclusion: Our findings added evidence indicating that ginger powder supplements might improve the symptoms of nausea or vomiting related to early pregnancy or motion sickness without significant adverse events.

Development of high-performance liquid chromatography-time-of-flight mass spectrometry for the simultaneous characterization and quantitative analysis of gingerol-related compounds in ginger products.

Liquid chromatography-time-of-flight mass spectrometry (LC-TOF/MS) was established for the simultaneous separation, identification, and quantification of gingerol-related compounds in ginger products. The established method has been shown to provide a satisfactory linearity (r > 0.999) in a wide range (5-5000 ng/mL), low limits of detection and quantification, high precision, and inter- and intraday repeatability. The detection sensitivity of gingerols and shogaols by TOF/MS was 70-100 times higher than conventional UV detection at 288 nm. In this study, 19 ginerol-related compounds in the samples were identified and quantified by the established LC-TOF/MS method. The dried ginger powder products contained the highest quantity of gingerol-related compounds (7126.3-13789.0 μg/g), followed by fresh ginger products (2007.9-2790.0 μg/g), powdered ginger tea products (77.29-81.75 μg/g), and hot water ginger extracts (54.59-123.23 μg/mL). Shogaols were not found in fresh gingers. This paper represents the first report on the LC-TOF/MS analysis for the simultaneous characterization and quantification of gingerol-related compounds in ginger products.
