- چکیده انگلیسی: Objective(s) The aim of the present study was to compare the therapeutic indices of several agents used in treatment of inflammatory conditions which included: Vitamin E, hydro-alcoholic extracts of Glycyrrhiza glabra, Matricaria aurea, dexamethasone, piroxicam and diclofenac using Wehi-164 fibrosarcoma cells. Materials and Methods Cytotoxicity evaluation was based on vital dye exclusion assay. Matrix-metalloproteinases inhibition (MMPI) was assessed by gelatinase zymography method. The collected data were used to estimate the IC50 (50% MMPI concentration), LC50 (50% cytotoxicity concentration) and the therapeutic index (LC50/IC50). Results Among the natural anti-inflammatory agents used, M. aurea was the least toxic and the most effective inhibitor of MMP. Vitamin E not only increased MMP activity, but also was the most toxic of all the agents tested. Next in terms of toxicity to vitamin E was G. glabra. Diclofenac was more toxic than both piroxicam and dexamethasone. Conclusion Findings from this study suggest that medicinal plants reputed to have anti-inflammatory properties are not equally effective and safe. In order to assess the implications of these findings, further in vitro and in vivo studies are needed.

- چکیده انگلیسی: Background and aims: Kombucha is an ancient food and healing source with Asian origin. Kombucha consists of a wide range of acids, including vitamin C, organic materials, enzymes, and B-group vitamins, which has provided it with immense value. This study was aimed to investigate the effects of Kombucha tea consumption on hepatic UDPGT enzyme in mice. Methods: In this experimental study, 21 small male albino mice and CD-1 genus were used. Albino mice species were purchased from serum Institute in Karaj Hisarak. Mice with a weight between 18 to 25 g were selected. Animals were kept in triplex group in polycarbonate cages. Animal rooms were equipped with air-conditioner. Ambient temperature was retained at about 22°C, and humidity 50%. A light cycle was set at 12 hours brightness and 12 hours darkness. The intensive diet was used that produced by animal Pars feeds for mice feeding. Finally, UDPGA enzyme was measured. Results: Consumption of kombucha tea for seven days of experiment caused a significant increase in enzyme activity in mice liver UDPGT compared to the negative control group, from the first day until the seventh day of experiment. Conclusion: Kombucha tea induced the UDPGT enzyme; thus, it accelerated the detoxification of the body and should be cautioned about simultaneous administration of this beverage with some drugs (such as steroids, acetaminophen, cardio– vascular medicine, etc.) that they metabolize through conjugation. Medical community in this case must be justified and their opinion must be considered when people are using this tea. Finally, kombucha tea consumption did not increase the liver weight. So, UDPGT induction was not the reason of liver weight increase.
