Background/Aim. The beneficial effects of medicinal plants are well-known from the ancient times. However, expansion of phytopharmacy and phytotherapy occured during the last decades. Medicinal plants can absorb environmental contaminants from the ground and consequently may cause harmful effects on human health. Quality control usually comprises standard methodology which includes macroscopic identification and examination of active ingredients. Additionaly, there is a permanent need to control the level of pollutants in herbs, with a particular attention to the level of toxic metals. In this study we estimated the level of contamination by determining the content of cadmium (Cd) in the herbs of Hypericum perforatum and Thymus serpyllum collected from the different localities of the mountains Rtanj and Ozren. Methods. Herbs of investigated plants were collected during July 2005 from various localities of Rtanj and Ozren mountains. After drying, homogenization and mineralization, Cd content was determined by atomic absorption spectrophotometry. Results. The obtained results show that Cd content varies significantly in Hypericum perforatum samples collected. The lowest Cd level was found in samples from the one of Rtanj localities (0.25 mg Cd/kg), while the highest was observed in Hypericum perforatum from Ozren locality (1.24 mg/kg). Levels of Cd in the three of four investigated localities were higher than pro posed by WHO (0.3 mg/kg dried herb material). In all investigated samples of Thymus serpyllum herbs Cd levels were below the limit of detection of analytical method (0.2 mg Cd/kg dried materials). Conclusion. This work contributes to the issue of Cd content in Hypericum perforatum and Thymus serpyllum grown in localities of Rtanj and Ozren, and implies the importance for systemic control of Cd content in Hypericum species in order to provide safety of their preparations. Furthermore, regarding Cd toxicity, maximal permissible level of Cd in plant material should be evaluated and established concerning national legislative frame.

Hypericum Perforatum L

Background: Continuous and indiscriminate use of chemical drugs causes resistance to microorganisms, which in turn weakens the effect of drugs. This adverse event is associated with an increased number of drugs used by patients and the tendency to use compounds with newer and stronger formulations. Furthermore, the essential oils of several plants contain a significant inhibitory effect on pathogenic microorganisms. Objectives: Hence, the current study intended to evaluate the antimicrobial activity of some medicinal plants on some standard human pathogenic bacteria and Candida albicans fungi isolated from women. Methods: Leaves of Cichorium intybus L., Hypericum perforatum L., Lavandula angustifolia, Thymus vulgaris L., and Taxus baccata L. were collected and analyzed in the botanical laboratory of the University of Zabol. Then, the ethanolic extract was prepared using 40 g of dried leaves in 400 cc of ethanol. Standard bacteria and fungi were obtained from the center for genetic and biological resources of Iran. To determine the activity of free radical trapping, diphenylpicryl hydrazyl was used, and then the antimicrobial effects were investigated by diffusion method in Müller-Hinton agar medium using 6 mm paper disks according to the Bauer and Kirby instructions. Statistical calculations were administered using Statistx Ver10. Mean comparisons were performed using the LSD at the 1% level, and Excel was also used to draw the shapes. Results: The diameter of the inhibitory zone of plant extracts against standard bacteria and clinical fungi of Candida albicans at a dilution of 100 ppm was analyzed, which revealed different effects (P < 0.01). Taxus baccata L., with a 15 mm diameter growth zone, showed the highest effect on inhibiting the growth of Bacillus cereus and Pseudomonas aeruginosa. Hypericum perforatum L. with a diameter of 15 mm was found as the most useful plant in inhibiting Shigella dysentery., with a diameter of 10 mm, was the most useful plant in inhibiting the growth of Escherichia coli. The Taxus baccata L., with a maximum growth inhibition zone diameter (20 mm), has been the most effective plant against Candida albicans. Conclusions: Considering the side effects of chemical drugs and antibiotics as well as the significant effect of medicinal plant extracts used in this study, the Taxus baccata L. was the most useful plant on inhibiting Candida albicans, Bacillus cereus, and Pseudomonas aeruginosa. Moreover, Hypericum perforatum L. was found as the most useful plant to control the growth of Escherichia coli.

This study was carried out to test the possibility of hexavalent chromium administration through drinking water to induce the structural damage in rat�s adrenal glands and the possibility of Hypericum perforatum extract to faith against chromium aggression. Chromium induced cellular stress was determined by the expression level assessment of the Bcl2 genes family, known to modulate the apoptotic pathway. Obtained results showed that exposure to chromium altered adrenal glands morphology, by induction of apoptosis. When Hypericum perforatum extract was administered expression level of Bcl2 genes and histological lesions in adrenal glands were significantly reduced.
