ABSTRACT: This study analyzed the effectiveness of the essential oil of Aloysia triphylla (EOA) as an anesthetic and stress reducing agent in the transport of fat snook ( Centropomus parallelus ). Juveniles were exposed to different concentrations of EOA (seawater-adapted: 25-300μL L-1; freshwater-adapted: 200μL L-1) to identify the anesthetic induction and recovery times. In an additional experiment, seawater-adapted fat snook were transported in plastic bags with 10 or 20μL L-1 EOA for 6 or 24h. The increased concentration of EOA proportionally decreased the time required for anesthesia induction. Mortality was 30 and 70% in fat snook transported with 10 and 20µL L-1, respectively, 24h after transport. The addition of 20µL L-1 EOA significantly reduced...

Meneses,J.O.; Couto,M.V.S. do; Sousa,N.C.; Cunha,F. dos S.; Abe,H.A.; Ramos,F.M.; Chagas,E.C.; Chaves,F.C.M.; Martins,M.L.; Maria,A.N.; Carneiro,P.C F.; Fujimoto,R.Y..
ABSTRACT The phythotherapy is an alternative to use of chemotherapeutical agents against monogenean infection. This study evaluated the anthelmintic activity of essential oil Ocimum gratissimum against monogenean Cichlidogyrus tilapiae as well as its acute toxicity in tilapia juveniles. The mean lethal concentration (LC50) and different concentrations of the essential oil, both in vitro and in vivo assays (short and long-term baths) were assessed. The LC50 was 40.70mg.L-1 and in the in vitro assay this concentration showed 80% efficacy at the last two hours and in the in vivo assay 65.87% efficacy in long-term bath. However, it provoked morphological alterations on the gills such as hyperplasia and edema. The parasites exposure at the highest concentration...

In vitro antifungal activity of four chemotypes of Lippia alba (Verbenaceae) essential oils against Alternaria solani (Pleosporeaceae) isolates Anais da ABC (AABC)
TOMAZONI,ELISA Z.; PANSERA,MÁRCIA R.; PAULETTI,GABRIEL F.; MOURA,SIDNEI; RIBEIRO,RUTE T.S.; SCHWAMBACH,JOSÉLI.
Several volatile natural compounds produced by plant secondary metabolism have been proven to present antimicrobial action, enabling their use in phytopathogen control. They also present low environmental impact when compared to conventional pesticides. Essential oils contain these compounds and can be found in several plant species, such as Lippia alba (Mill.) N.E. Brown (Verbenaceae). Essential oils of four chemotypes of L. alba, characterized by their major compounds, namely camphor, citral, linalool and camphor/1,8-cineole, were tested against the phytopathogen Alternaria solani Sorauer (Pleosporaceae), which causes early blight on tomatoes and is responsible for great economic losses regarding production. Essential oils antifungal action was tested in...

XU,Li-na; LU,Bi-nan; HU,Ming-ming; XU,You-wei; HAN,Xu; QI,Yan; PENG,Jin-yong.
Berberine, a constituent of some traditional Chinese medicinal plants, has been reported to have cytotoxicity effects on different human cancer cell lines. There is no available information about the effects and mechanism of action of berberine on human colon cancer cell line HCT-8. In this paper, the cytotoxicity of berberine on HCT-8 cancer cells was investigated by MTT assay, fluorescence microscopy and flow cytometry analysis. Our data revealed that berberine could significantly inhibit the growth of HCT-8 cells in a dose- and time-dependent manner. Morphology of apoptotic cells was studied with acridine orange/ethidium bromide staining. The concentrations of lactate dehydrogenase and both acid and alkaline phosphatases were significantly increased in...

Plant Extracts as an Alternative to Control Leucoptera coffeella (Guérin-Mèneville) (Lepidoptera: Lyonetiidae) Neotropical Entomology
Alves,DS; Oliveira,DF; Carvalho,GA; Santos Jr,HM dos; Carvalho,DA; Santos,MAI; Carvalho,HWP de.
We evaluated the effects of crude extracts from the plantain Plantago lanceolata and the bitter gourd Momordica charantia on the oviposition preference and development of the coffee leaf miner Leucoptera coffeella Guérin-Mèneville & Perrottet under laboratory and/or greenhouse conditions. The ovicidal effects of these extracts were also studied in a greenhouse. Plantago lanceolata and M. charantia extracts also underwent fractionation directed by oviposition tests with the coffee leaf miner. The extracts of both plants reduced L. coffeella oviposition and egg hatching, apparently as a result of action of plant metabolites on the embryo. Adults originating from eggs treated with the extracts exhibited similar survival rates, but a higher female/male...

This study evaluated the safety of Lafoensia pacari A. St.-Hil. (Lythraceae) stem bark hydroalcoholic extract (LPE) through acute and subchronic toxicological assessments in mice. In the acute toxicity evaluation, a single 2000 mg/kg oral dose of LPE was administered to mice and clinical observations were conducted for 14 days. For subchronic toxicity, LPE doses (6.25-1000 mg/kg) were administered orally for 28 days and biochemical, hematological, histopathological analyses and renal and liver expression of Ki-67 were carried out. The acute oral toxicity evaluation of LPE showed no toxicity in mice and it was was classified as category 5 (LD50>2000-5000 mg/kg). In a repeated dose 28-day toxicity study, LPE (100-1000 mg/kg) led to an increase in...
