Objective: Morinda citrifolia is one of the most significant plants that are used in traditional medicine. However, details of the dermal toxicity of M.

Systemic toxicity tests are in-vivo assays used to assess the impairment or activation of a system — rather than the impairment of individual cells or organs. Categories are based on duration of exposure and dose route. Acute systemic toxicity assaying is the most commonly performed, and includes a single exposure with a hour observation period.

Acute, subacute and chronic toxicity of fosfosal

The objective of this study was to determine the acute one single dose , subacute 14 days , and sub-chronic 90 days toxicity of an aqueous virgin olive oil VOO extract rich in hydroxytyrosol in rats. Clinical signs, body weight, functional observations of sensory and motor reactivity, hematological and biochemical analyses, and macroscopic and microscopic histopathology were evaluated. No adverse effects were observed after the administration of the different doses of the hydroxytyrosol-rich VOO extract, which suggests that the enrichment of VOO in its phenolic compound is safe, and can be used as functional foods for the treatment of chronic degenerative diseases. There is clinical evidence that the Mediterranean diet is associated with beneficial health effects, in terms of morbidity and mortality [ 1 ], and is highly recommended for cardiovascular risk patients [ 2 ]. Virgin olive oil VOO is the main fatty source and is responsible for many of the health benefits attributed to this dietary pattern [ 3 ].

Short-term inhalation toxicity studies with respirable polymeric methylene diphenyl diisocyanate polymeric MDI aerosol were performed in rats. Exposure of 4-week-old rats to 0, 2. A week study with 6-week-old rats exposed to 0. In a second week study with 6-week-old rats, using exposure concentrations of 0, 4. Rats exposed to 8. Most of the histopathological changes seen at the higher concentrations were also seen at 4. At the end of the 4-week posttreatment period the microscopical changes in nose, lungs, and mediastinal lymph nodes were still present but generally to a much less degree than at the end of the exposure period.

Metrics details. Azadirachta indica , Khaya senegalensis , Anogeissus leiocarpus and Tamarindus indica are important ethnomedicinal plants used for health mitigation since the history of mankind. They are used discretionarily in folkloric medicine on the premise that they are natural products devoid of synthetic preservatives. However, nature endows plants with metabolites for warding off potential attacks from animals and the environment. Some of these metabolites are responsible for toxicity of some plants. Furthermore, drug-induced liver injuries and nephrotoxicity are the leading causes of pharmaceutical attrition of promising drug candidates in clinical trials.

Oxyclozanide is an effective anthelmintic and has shown good properties in other ways including anti-adenovirus, anti-biofilm, antifungal, and antibacterial activity. This study aimed to investigate the acute and subacute days repeated dose oral toxicity of an oxyclozanide suspension in Wistar rats. During the days time period, no obvious adverse effects or death were detected. Histopathological changes were observed in the heart, liver, and kidney of animals treated with high dose of oxyclozanide. Based on the hematological parameters, there were no statistical differences between the oxyclozanide-treated group and the control group. Infectious parasitic diseases have become a serious threat to animal health and productivity in developing countries 1 — 3. Among them, fascioliasis, as a zoonotic disease, is a food-borne parasitic disease, which is transmitted to certain hosts, humans, and other herbivorous mammals through contaminated water or green vegetables 4.

Ethnopharmacological Relevance. Haloxylon scoparium Pomel is a herbal medicine traditionally used for treating scorpions and snakebite, diabetes, and stomachache as well as several other diseases. No systematic study of the potential toxicity of the plant has been described.

Mice, rats, sometimes rabbits or dogs. Dose Administration 3 to 4 doses given by the same routes as previous toxicity tests. Length depends on intended period of human exposure. Parameters Absorption rate quantitation in blood, urine, feces, vaginal fluids, and tissue samples. Duration Irritation — one hour to three weeks after a single topical or corneal administration. Sensitization — intradermal or topical induction doses followed by topical challenges with a non-irritating dose 6 — 8 weeks total. Dose Administration Rodents: Intraperitoneal preferred , or expected route of human exposure.

Acute and subacute toxicity studies of the latex and of the ethanolic extract of the leaves of Synadenium umbellatum Pax in rats. ISSN X. The use of medicinal plants has been being very significant in the last years, being the use encouraged by WHO. Synadenium umbellatum Pax, Euphorbiacea popularly known as cola-note, cancerola, miraculous has the latex used empirically as anti-cancerous and anti-inflammatory. For there being toxic species in this family and aiming at the safety in the use of vegetable extracts, such study evaluated the pre-clinical toxicity of the latex and of the ethanolic extract of the leaves EEL of S.

 Электроснабжение уже наверняка восстановили.  - Он открыл жалюзи. - Все еще темно? - спросила Мидж.

 Мистер, - сказала она дрожащим голосом, - я не говорила вам, как меня зовут. Откуда вы узнали.
