ABSTRACT
Background: Safe drinking water is one of the main factors in improving health status of the population. The aim of this study was assessment of the microbiological quality, determination of pH and residual chlorine in water coolers' drinking water in educational centers of Zanjan University of medical Sciences in 2015 and comparing the results with the Iranian national standards
Methods: In this cross-sectional study, water samples of all used water cooler apparatuses were sampled and transferred rapidly to the laboratory. pH and residual free chlorine were measured by pH meter and Chlorine Residual Testing kit, respectively. Total coliforms, Escherichia coli, Mold and yeasts count were enumerated according to the Iranian national standards No. 1011, 3759, 5271 and 10899-1, respectively. Data were analyzed through the statistical softwares
Results: The obtained results indicated that 44.44% of the samples were non-standard because of low residual chlorine. 44.44% and 27.8% of the taken water samples of water cooler dispensers were contaminated with mold or yeast and Escherichia coli, respectively
Conclusion: According to some microbial contamination in water samples of water cooler devices to ensure availability clean water to consumers [students and hospital's visitors] continuous monitoring, proper maintenance and regular inspection of the water cooler dispensers seems necessary
ABSTRACT
Background: Fluoride is an essential nutrient for the human body. The major routes of fluoride intake include food and drinking water, though the absorption of fluoride from food is much easier. The aim of this study was to evaluate the amount of fluoride in the soil and tomato and onion crops on farms of Zanjan
Methods: Three farms of each crop [tomato and onion] were selected randomly. Each farm was divided into 10 sections, and one sample of soil and crop of each section was taken which means 120 samples in total. Fluoride concentrations in the soil and crops were measured using the Ion Selective Electrode [ISE] and repeated 3 times
Results: The mean concentration of fluoride in soil samples from studied farms in Zanjan was 0.83 +/- 0.17 mg/kg. The mean concentrations of fluoride in tomatoes and onions of Zanjan were observed 2.10 +/- 0.80 and 2.23 +/- 0.64 mg/kg, respectively
Conclusion: There was no significant difference between fluoride concentration in tomatoes and onions, although there was a significant difference between the amount of fluoride in the soils of studied farms [Pv < 0.024]. No significant correlation was observed between the fluoride levels of soils and the fluoride levels of tomatoes [R2 = 0.126] and onions [R2 = 0.008]
ABSTRACT
Objective: To identify medicinal plants witch are used for headaches and migraines treatment in Lorestan province of Iran. Methods: Traditional medical herbs information was acquired from indigenous people with the cooperation of health centers of Doroud, Borujerd, Khorramabad, Aleshtar Poldokhtar, Aligoodarz, Nourabad and Kouhdasht cities. The prepared questionnaires were given to trained health volunteers. They attended in the villages and recorded people beliefs in herbal therapy by the questionnaires. Results: The results of this study showed that people used 15 herbs traditionally to treat headaches. Because of the importance of the medicinal plants in the study area, it is neccessary to determine sociological studies the plenty of plant species. Conclusions: Because of the widespread use of traditional medicinal plants and high tendency to herbal medicine and traditional medicine, more extensive researches should be designed in several areas of pharmacy and pharmacology of medicinal plants to prepare proper information for pharmaceutical industries.
ABSTRACT
Parasites and parasitic diseases are widely spread in the world. Their adverse effects on health and social-economic society cause tremendous public health problems. Parasitic infections in different ways (water, soil, food and vegetables) can affect humans and induce other complications such as gastrointestinal disorders, malnutrition, anemia and allergies and sometimes even life threatening. Medicinal plants are being widely used, either as a single drug or in combination with synthetic drugs. These medicinal plants are considered as a valuable source of unique natural products and drugs for development of medicines against various disorders and diseases. In this article the recently published papers about medicinal plants and parasites were reviewed, using scientific sites such as Medline, PubMed and Google Scholar. The used terms included: herbal medicine, medicinal plants, and antihelmintic drugs, antinematoda, anticestoda, antitrematoda. From the above collected literature it might be concluded that these plants are promising potential sources for preparation of new drugs or for pharmacological and therapeutic applications.
