RESUMO
Daurian Thermopsis (Thermopsis daurica Czefr.),Gobian Thyme(Thymus gobicusTschern.) and Mogilev Mallow (Malva mohileviensis Downer) are separately used as mucolytic and anti- inflammatory treatment in non-conventional medicine. Therefore, we prepared infusion of these herbals compound called as a Tetima. It is important to produce new pharmaceutical preparation that mucolytic effective for upper and lower respiratory tract inflammatory disease. Despite the wide use of this plants as herbal medicine in the treatment of respiratory tract diseases, their toxicity is still unknown. Therefore, we evaluated the possiblesubchronic toxic effects of Tetima herbal compound inrats. Tetima herbal compound infusion was prepared in distilled water (1:10). We used 15 Wistar breed rats (230-370 gr) in this study. Subchronic toxicity study for 28 days was done by oral administration at doses of 0.5ml normal saline (control) and 200 mg/kg, 400 mg/kg of infusion in Wistar ratsThe obtained data revealed that oral administration of Tetima in rats for 28 successive days had no significant changes the hematological parameters in rats all over the period of the experiment, and there are no significant increases in the activity of aspartate aminotransferase, alanine aminotransferase, creatinine and urea, between control and treated groups (p>0.05). The histopathological studies of the major vital organs like liver, kidney and heart recovered from the control and treated groups showed normal architecture suggesting no detrimental changes and morphological disturbances. These results show that the Tetima herbal compound is low toxic in subchronic toxicity study.
RESUMO
The Mongolian plants considered to possess medicinal properties may contain novel compounds since they are exposed to severe conditions; such plants could become good candidates for modern drug discovery programs. Daurian Thermopsis (Thermopsis lanceolata R.Br.= Th.dahurica Czefr.), Gobian Thyme (Thymus gobicus Tschern.) and Mogilev Mallow (Malva mohileviensis Downer) are separately used as mucolytic and anti-inflammatory treatment in non-conventional medicine. Therefore, weprepared extract of these herbals compound called as a Tetima and to evaluate it’s acute toxicity. It isimportant to produce mucolytic effective new pharmaceutical preparation used for upper and lowerrespiratory tract inflammatory disease.Tetima herbal compound extract was prepared in ethanol, the ratio of herbals to ethanol was 1:10. Healthy 25 white albino mice (male weighing between 17-30 gram) used in this study. They were kept in large airy cages in groups of 5 animals per cage with free access to food and water. Five doses (8-20 g/kg) were then chosen for the determination of intraperitoneal LD50 in mice and given to five groups of albino mice. The animals were observed for first 2 hours and then at 6th and 24th hour for any toxicsymptoms. After 24 hours, the number of deceased mice was counted in each group. The percentage of animals that died at each dose level was transformed and then LD50 determined by the methods of Karber and Pershin.G.N.The LD50 of Tetima herbal compound in mice was determined to be 14.3 g/kg after intraperitonealinjection. There was no difference occurred between Karber and Pershin methods to evaluate acute toxicity. In the animals receiving intraperitoneal injection, the abdominal muscle contractions and ataxia was observed, which persisted for few hours. At the 6th hour they were drowsy and less responsive. The severity of these effects was related to the level of dose. However, at 24th hour most of the survivors had recovered from these symptoms.Tetima herbal compound extract is a relatively safe, particularly when given intraperitoneal inject toexperimental animals.
