  • investigation of Acute Toxicity of deltamethrin on guppies poecilia reticulata
    Ecotoxicology and Environmental Safety, 2003
    Co-Authors: Rukiye Viran, Figen Erkoc, Hilal Polat, Oner Kocak
    Abstract:

    Deltamethrin, a synthetic pyrethroid pesticide contaminating aquatic ecosystems as a potential toxic pollutant, was investigated in the present study for Acute Toxicity. Guppy fish (Poecilia reticulata) were selected for the bioassay experiments. The 48-h LC50 was determined for the guppies. The experiments were repeated three times and a total of 210 guppies were used. The static test method of Acute Toxicity test was used. In addition, behavioral changes at each deltamethrin concentration were determined for the individuals. Data obtained from the deltamethrin Acute Toxicity tests were evaluated using the Probit Analysis Statistical Method. The 48-h LC50 value for guppy was estimated as 5.13 microg/L.

    Abstract:

    Permethrin, a synthetic pyrethroid pesticide and potential toxic pollutant contaminating aquatic ecosystems, was investigated in the present study for Acute Toxicity. Guppy fish (Poecilia reticulata) were selected for the bioassay experiments. The experiments were repeated 3 times and the 48-h LC50 was determined for the guppies. The static test method of Acute Toxicity test was used. Water temperature was regulated at 20 � 1 C. In addition, behavioral changes at each permethrin concentration were observed for the individual fish. Data obtained from the permethrin Acute Toxicity tests were evaluated using the probit analysis statistical method. The 48-h LC50 value for guppy was estimated as 245.7 lg/l. Values in the range of 0.05–97.0 lg/l have been reported for various other fish species. 2003 Elsevier Science Ltd. All rights reserved.

    Abstract:

    Beta-cypermethrin, a synthetic pyrethroid pesticide and potential toxic pollutant, contaminating aquatic ecosystems was investigated in the present study for Acute Toxicity. Guppy fish (Poecilia reticulata) was selected for the bioassay experiments. The experiments were repeated three times and the 48-h LC50 was determined for the guppies. The static test method of Acute Toxicity test was used. Water temperature was regulated at 22 +/- 1 degrees C. In addition, behavioral changes at each beta-cypermethrin concentration were observed for the individual fish. Data obtained from the beta-cypermethrin Acute Toxicity tests were evaluated using the probit analysis statistical method. The 48-h LC50 value for guppy was estimated as 21.4 microg/l.

  • investigation of Acute Toxicity of fenitrothion on peppered corydoras corydoras paleatus jenyns 1842
    Chemosphere, 2004
    Co-Authors: Rabia Sarikaya, Mahmut Selvi, Figen Erkoc
    Abstract:

    Abstract Fenitrothion, as an organophosphothionate insecticide, is a contact insecticide and selective acaricide, also used as a vector control agent for malaria in public health programs. A 96 h LC 50 value of fenitrothion, a potential toxic pollutant contaminating aquatic ecosystems, was determined on the adult peppered corydoras ( Corydoras paleatus ). The experiments were repeated three times. The static test method of Acute Toxicity test was used. Water temperature was regulated at 23 ± 1 °C. In addition, behavioral changes at each fenitrothion concentration were observed for the individual fish. Data obtained from Acute Toxicity tests were evaluated using the Probit Analysis Statistical Method. The 96 h LC 50 value for peppered corydoras was estimated as 3.51 mg/l.

  • Acute Toxicity and anti inflammatory activity of aqueous ethanol extract of root bark of ximenia americana l olacaceae
    African Journal of Pharmacy and Pharmacology, 2011
    Co-Authors: Onifade Alfattah Olabissi, Ouedraogo Moussa, Ouedraogo Moustapha, Zongo Frank Edgard, O Eleonore, Lompo Marius, Guissou Innocent Pierre
    Abstract:

    Ximenia americana L. (Olacaceae) is a folk medicinal plant used in Burkina Faso to treat inflammatory, noxious and infectious diseases. The aim of this study was to evaluate anti-inflammatory properties of aqueous ethanol extract of root bark of the plant and evaluate its Acute Toxicity. Carrageenan was used to induce oedema and leukocyte migration; acetic acid was used to induce vascular permeability in order to evaluate anti-inflammatory properties of the plant extract. The Acute Toxicity was evaluated using mice. The aqueous ethanol extract of X. americana administered intraperitoneally is fairly toxic in mice with a LD50 of 345 mg/kg of body weight. The extract inhibited paw swelling, polymorphonuclear neutrophil and leukocyte migration induced by carrageenan. Moreover, the extract (10, 30 and 100 mg/kg) reduced vascular permeability induced by acetic acid. Aqueous ethanol extract of root bark of X. americana (Olacaceae) possesses anti- inflammatory properties by inhibiting oedema, pain, cell migration and increased vascular permeability.   Key words: Ximenia americana, anti-inflammatory activity, Acute Toxicity, root bark.

  • anti inflammatory analgesic activity and Acute Toxicity of sida cordifolia l malva branca
    Journal of Ethnopharmacology, 2000
    Co-Authors: E M Franzotti, C V F Santos, H M S L Rodrigues, R H V Mourao, M R Andrade, Angelo R Antoniolli
    Abstract:

    Sida cordifolia L. (Malvaceae) is used in folk medicine for the treatment of inflammation of the oral mucosa, blenorrhea, asthmatic bronchitis and nasal congestion. The anti-inflammatory, analgesic effects and Acute Toxicity of an aqueous extract of S. cordifolia were evaluated in animal models. The extract was prepared using leaves collected before the flowering period. The aqueous extract (AE) showed a significant inhibition of carrageenin-induced rat paw edema at a dose of 400 mg/kg administered orally, but did not block the edema induced by arachidonic acid. The AE also increased the latency period for mice in the hot plate test, and inhibited the number of writhes produced by acetic acid at the oral dose of 400 mg/kg. The aqueous extract of S. cordifolia showed low Acute Toxicity in mice.
