Jaundice is the commonest ailments affecting the citizens of both developed and poor Asians countries including Iran. An ethnobotanical survey of plants used by the traditional healers for the treatment of jaundice was conducted in the Mashhad city, Northeastern Iran. A total of 37 plants belonging to 32 genera and 26 families have been documented for their therapeutic use against jaundice. The plant families which contained the most commonly used species for their effects are: Fabaceae (5 species), Polygonaceae (4 sp.), Asteraceae (3 sp.), Plantaginaceae (2 sp.) and Salicaceae (2 sp.). The plants were arranged with correct nomenclature along with their common name, family, the part used and their medicinal value. The use of decoction is the most preferred method of herbal preparation. In all cases, the treatment involved oral administration of the extracts 2 to 3 times daily from a week to month till the problem disappears. Cichorium intybus, Salix alba, Cotoneaster nummularius, Descurainia sophia, Malva sylvestris, Berberis integrrima, Rumex acetosella, Phyllanthus emblica and Alhagi maurorum were repeatedly mentioned by the traditional healers as the most widely used for the treatment of jaundice in the study area. The study indicates that the local inhabitants rely on medicinal plants for treatment. This paper suggested that further clinical experimentation is needed to scientifically evaluate these widely used herbal remedies for possible bioactive effects. © 2014 by School of Pharmacy Shaheed Beheshti University of Medical Sciences and Health Services.

Objective: The cerebellum is a key structure involved in coordinated motor planning, cognition, learning and memory functions. This study presents a permanent model of a toxin produced cerebellar lesion characterized according to contemporary motor and cognitive abnormalities.Materials and Methods: In this experimental study, slow administration of quinolinic acid (QA, 5 μl of 200 μmol, 1 μl/minute) in the right cerebellar hemisphere (lobule VI) caused noticeable motor and cognitive disturbances along with cellular degeneration in all treated animals. We assessed behavioral and histopathological studies over ten weeks after QA treatment. The data were analyzed with ANOVA and the studentfs t test.Results: The QA treated group showed marked motor learning deficits on the rotating rod test (p≤0.0001), locomotor asymmetry on the cylinder test (p≤0.0001), dysmetria on the beam balance test (p≤0.0001), abnormalities in neuromuscular strength on the hang wire test (p≤0.0001), spatial memory deficits in the Morris water maze (MWM, p≤0.001) and fear conditioned memory on the passive avoidance test (p≤0.01) over a ten-week period compared with the control animals. Histopathological analysis showed loss of Purkinje cells (p≤0.001) and granular cell density (p≤0.0001) in the lesioned hemisphere of the cerebellum.Conclusion: Results of the present study show that QA can remove numerous cells which respond to this toxin in hemispheric lobule VI and thus provide a potential model for functional and cell-based studies.

Human mesenchymal stem cells (hMSCs) have been presented as alternative sources of cells to be transplanted into the brain in neurodegenerative disorders. In this regard, the efficacy of hMSCs transplants in reducing motor and non-motor deficits in a quinolinic acid (QA) rat model of Huntington’s disease (HD) was tested in the present study. After unilateral lesions in striatum by QA, the isolated and purified hMSCs from liposuction of healthy male donors were transplanted into the damaged striatum of the rats. The cells were stably transfected with a vector containing TurboGFP and JRed to make it possible to trace them after transplantation. Animals were tested by motor and non-motor function tests at different times after the cell transplantation. The hMSCs survived 7 weeks in the brains. An improvement was observed in behavioral tests such as apomophine-induced rotation, hanging wire, and rotarod for the hMSC-treated rats. Anxiety like behaviors were decreased in hMSCs-treated animals when they were examined using open field, elevated plus maze, light and dark box, and novelty suppressed feeding tests. Compared to QA, the hMSCs treatment decreased motor activities. These results confirmed the potential efficacy of hMSCs in treatment of behavioral defects in HD. Generally, the data demonstrated that xenologous transplantation of hMSCs could be considered as an ideal candidate for treatment of neurodegenerative diseases, especially HD. © 2015 W. S.
