Objective: Aristolochia albida Duch is frequently used by alternative medicine to treat some pathologies like hepatitis. Our main objective was to evaluate the acute oral toxicity of the ethanolic extract of this plant.Methods: Exploratory tests for acute oral toxicity are performed in vivo on Wistar albino rats in a limit test of 2000 mg/kg for 14 d in accordance with the OECD Guidelines 423. The clinical signs were observed every day, followed by measurement of body weight change, the haematological and biochemical examinations were executed and statistical analysis was performed. Results: The various clinical signs observed after administration and for 14 d were recorded and no mortality was observed. With the exception of white blood cells, mean cell volume and platelets with statistically significant difference in control (p<0.05), all the haematological parameters showed an insignificant statistical difference to the control ratio (p>0.05). For biochemical parameters, except blood glucose and total protein of control batches, which show a significant statistical difference after 14 d (p>0.05), all the biochemical parameters show the statistically insignificant difference for test and controls batches (p>0.05) as well as the weight variation of the animals.Conclusion: The ethanolic extract of the leaves of A. albida Duch (EEAr) had not toxic effect on the biochemical and hematological parameters studied at a dose of 2000 mg/kg. The lethal dose is therefore over 2000 mg/kg.

Hematological And Biochemical Parameters

The tubers of Hydnophytum formicarum Jack. have been used for the treatment of rheumatism, liver and intestinal diseases in the traditional medicine of Vietnam. The 50% ethanolic extract of H. formicarum (EEHF) has been proved anti-inflammatory and analgesic effects as well as hepatoprotective activity at the oral doses of 100 and 200 mg/kg in Swiss albino mice. The aim of this work was to study on the subacute oral toxicity of the EEHF at the doses of 100 and 200 mg/kg for 30 and 60 consecutive days in both sexes of mice. The observations were undertaken on the mortality, the body weights, the toxic signs, hematological and biochemical parameters. At the end of the experiment, the histopathology of liver and kidneys was studied. The results showed that the 100 mg/kg of EEHF did not cause any toxic signs in mice. There was no significant difference of hematological and biochemical parameters between the treated animals and the controls. Histopathological examinations of livers and kidneys showed no significant difference suggesting no morphological disturbances in treated mice. In conclusion, the results indicated that the EEHF did not cause any subacute toxicity in mice at the dose of 100 mg/kg, providing the evidence of the safety of health products from this medicinal plant.

<p>Jackfruit (Artocarpus heterophyllus) root extract, with a bronchodilating agent, is traditionally used for treating asthma. To provide a scientific basis for such claim, this study was conducted to evaluate the safety and efficacy of the formulated syrup of such extract by determining its acute oral toxicity level, approximate effective dose, the significant difference in the total leukocyte count (TLC), total eosinophil count (TEC) and histopathologic evaluation of lung tissue. Female Swiss mice were used to determine the toxicity at selected fixed dose levels of 5, 50, 300 and 2000 mg/kg. Approximate Effective Dose (AED) determination was conducted using female albino rats with a logarithmic increase by 0.6 intervals. Animals were administered with alumovalbumin and desired dose of root extract, respectively. Blood samples were collected for leukocyte and eosinophil counts. It was found that acute oral toxicity was at 2000mg/kg and 5000 mg/kg. AED has significant influence on TLC and TEC at dose levels of 15.85, 251.19, 1000 and 3981.07 mg/ kg. Analysis of Variance showed a significant difference in the mean of the decrease in the total leukocyte count due to the formulated syrup of root extract, Salbutamol (positive control) and plain syrup (negative control). Tukey’s multiple comparison tests, t-test and histopathologic evaluation on the group treated with Salbutamol and root extract formulation showed no significant difference on the TLC and TEC. Salbutamol was not significantly different from the formulated syrup. Hence, both treatments were effective as bronchodilating agents.</p>

Objectives: The present study was carried out to evaluate the hydroalcoholic extract of Mucuna pruriens (HAMP) seeds for its acute oral toxicity in albino rats. Methods: Acute oral toxicity of MP seed extract was assessed in albino rats with three different doses of the extract with 175, 550, and 2000 mg/ kg body weight. Body weight, mortality, and clinical signs were recorded on 0 (before administration), 7th, and 14th days. Rats were sacrificed after day 14 and observed for any histological changes in the brain, heart, liver, and kidney tissues. Rats were normal up to 1 h and exhibited dullness and piloerection after 1 h which continued up to 2–4 h of observation period on day 0 of administration. All animals appeared normal from day 1 to throughout the experimental procedure. Results: No significant changes in the histological structure of the liver, kidney, and heart were noticed except mild congestion and hydropic changes only in liver tissue seen for 2000 mg/kg body weight of HAMP seeds. The seed extract of MP is non-toxic to rats and did not show any mortality nor the behavioral changes. In addition, it showed an increase in the body weight with the administration up to 2000 mg/kg body weight. Conclusion: MP seed extract signified as neurosuppressant, and the drug can be used in the treatment of neurological disorders characterized by hyperactivity of the neurons. The present data could provide adequate confirmation of the safety of MP for further experimental studies on a standardized formulation of the seeds extract.

Objectives: The medications of plant-based, herb-mineral, and animal sources have been used by the conventional medics to maintain well-being and care for diseases ever since ancient times. The current study aimed to evaluate the acute and subacute toxicities of the ethanolic extract of Turnera aphrodisiaca (TA) leaves in albino rats. Methods: The acute toxicity studies were carried out where the maximum dosage of 5000 mg/kg body mass was used. The outcome reported for 24 h and singly daily for 2 weeks. The rats were weighed and a range of interpretations, for example, behavior, lesions, mortality, or any indication of sickness, was carried out daily once throughout the study. For the subacute study, four groups of ten animals (female rats) received 10% Tween 20 in distilled H2O (as control), and 250, 500, and 1000 mg/kg of newly developed extracts, correspondingly, every 24th h orally for about 4 weeks. At the ending of every study, hematological study and biochemical parameters were assessed. Results: No major variations (p>0.05) were experienced in the comparative organs, body mass, hematological, biochemical parameters, and offensive malfunctions, in comparison to control, with no mortality reported. Hence, the results of the study may direct the outcome that the intermediate-period oral administration of the TA leaves for 4 weeks does not produce toxicity. Conclusion: Due to these results, we may well wrap up that leaves of TA extract are non-toxic in all doses considered in this study and did not created any obvious signs in the acute and subacute oral toxicity studies.

Abstract Background: Two types of EBV (EBV1 and 2) have been shown to infect humans. This study aimed to detect the types of EBV that cause infectious mononucleosis and correlate these viral types with biochemical parameters (AST, ALT and GGT) in the metropolitan region of Belém from 2005 to 2016. Methods: A total of 76 cases of infectious mononucleosis were processed at the Instituto Evandro Chagas, Ananindeua, Brazil. PCR was used to analyze the EBNA3C region for the recognition of EBV types. Biochemical testing (AST, ALT and GGT) was performed by the COBAS INTEGRA clinical biochemistry PLUS 400 / ROCHE automatic analyzer. The data were evaluated using the Statistical Package for Social Science - SPSS 17.0 and GraphPadPrism 7.0 for Windows (GraphPad software, San Diego, CA, USA). Results: EBV1 infection was observed in 71.1% (54/76) of individuals, among whom those > 14 years constituted 66.7% (36/54); the average age was 23 years, and the number of women infected was higher (61.1% [33/54]) than that of men 38.9%[21/54]). The symptoms/clinical signs observed in infection by EBV1 were cervical lymphadenopathy in 64.8% (35/54), fever in 63% (34/54), headache and arthralgia in 20.3% (11/54), and exanthema in 18.5% (10/54). Infection by EBV2 was observed in only 17.1% (13/76) of cases. Coinfection by EBV1 and EBV2, most frequently showing symptoms of fever and cervical lymphadenopathy, occurred in 66.7% (6/9) and 55.6% (5/9) of individuals. Conclusion: EBV1 was predominant in 71% of clinical cases of infectious mononucleosis. The correlation of biochemical parameters in infection by EBV1, EBV2, and coinfection by EBV1/2 revealed a statistically significant difference in mean changes of EBV1 in individuals older than 14 years.

Background. Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. Objective. Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. Methods. The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. Results. No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg p < 0.01 . There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. Conclusion. The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats’ death after 90-day oral administration at 500 and 1000 mg.

Acute Toxicity Study

Pinnatoxin G (PnTx-G) is a marine cyclic imine toxin produced by the dinoflagellate Vulcanodinium rugosum, frequently detected in edible shellfish from Ingril Lagoon (France). As other pinnatoxins, to date, no human poisonings ascribed to consumption of PnTx-G contaminated seafood have been reported, despite its potent antagonism at nicotinic acetylcholine receptors and its high and fast-acting toxicity after intraperitoneal or oral administration in mice. The hazard characterization of PnTx-G by oral exposure is limited to a single acute toxicity study recording lethality and clinical signs in non-fasted mice treated by gavage or through voluntary food ingestion, which showed differences in PnTx-G toxic potency. Thus, an acute toxicity study was carried out using 3 h-fasted CD-1 female mice, administered by gavage with PnTx-G (8–450 µg kg−1). At the dose of 220 µg kg−1 and above, the toxin induced a rapid onset of clinical signs (piloerection, prostration, hypothermia, abdominal breathing, paralysis of the hind limbs, and cyanosis), leading to the death of mice within 30 min. Except for moderate mucosal degeneration in the small intestine recorded at doses of 300 µg kg−1, the toxin did not induce significant morphological changes in the other main organs and tissues, or alterations in blood chemistry parameters. This acute oral toxicity study allowed to calculate an oral LD50 for PnTx-G equal to 208 μg kg−1 (95% confidence limits: 155–281 µg kg−1) and to estimate a provisional NOEL of 120 µg kg−1.
