In our study, a wide range of dosing errors was common among patients with renal impairment that was common during hospitalization. Continued medical education in the field of clinical pharmacokinetics is important for physicians.

Background: Herbs have played a fundamental and essential role in the humans life since ancient times, especially those which are used as food and/or folk medicinedue to both their nutritive and curative properties.This study aimed to investigate new antilipase agents from tentraditional Palestinian edible and medicinal plants through inhibition of the absorption of dietary lipids. Methods: The anti-lipase activity for ten plants was evaluated and compared with the reference compound Orlistat by using the porcine pancreatic lipase inhibitory test which was conducted by using a UV-visible spectrophotometer. Results: The aqueous extracts of Vitis vinifera and Rhus coriaria had the highest antilipase effects with IC50 values 14.13 and 19.95 mcg/mL, respectively. Meanwhile, the organic extract of Origanum dayi had an IC50 value 18.62 mcg/mL. V. vinifera showed the highest porcine pancreatic lipase inhibitory effects when compared with Orlistat, which has an IC50 value 12.38 mcg/mL. Conclusions: According to the obtained results, V. vinifera, R. coriaria, and O. dayi can be considered a natural inhibitors of the pancreatic lipase enzyme as well as new players in obesity treatment. In fact, these plants can be freely and safely consumed in a daily diet or can be prepared as nutraceutical formulations to treat or prevent of obesity.

BackgroundPlants have been the primary source of medicines since life on earth; more than 50 % of existing cancer treatments are derived from plants.MethodsAn ethnopharmacological survey of herbal remedies used in cancer treatment was carried out in the West Bank/ Palestine. A questionnaire was distributed to one hundred and fifty herbalists, traditional healers and rural dwellers. Collected information included the names of plants, the used parts, types of cancers for which these plants were used and also their methods of preparation. To identify the most important species used, Factor of informant’s consensus (Fic), Fidelity level (Fl) and the Use-value (UV) were calculated.ResultsCollected data has shown that 72 plants are utilized for treatment of cancer, belonging to 44 families; from them Compositae and Lamiaceae were the most common. Leaves and fruits were the most commonly used parts, while decoctions, infusions and syrups were the main methods of preparation. Lung cancer was the most common type of cancer treated with these plants and Ephedra alata was the most commonly used plant for treatment of cancer in Palestine. The Fic was high for all the plants; Fl was 100 % for many plants, the highest UV (0.72) was for Ephedra alata.ConclusionsThis study showed that many herbal remedies are still used by herbalists in Palestine for treatment of cancer; some of them have been approved scientifically while others are not. A combined effort between informants and scientific institutions working in this field can help in the discovery of new anticancer agents. Moreover, scientists must explore the most suitable method of extraction, formulation and dose determination in order to achieve the best benefits from these herbals.

BackgroundThroughout history, every civilization in the world used plants or their derivatives for treatment or prevention of diseases. In Palestine as in many other countries, herbal medicines are broadly used in the treatment of wide range of diseases including urological diseases. The main objective of this research is to study the use of herbal remedies by herbalists and traditional healers for treatment of various urological diseases in the West Bank regions of Palestine and to assess their efficacy and safety through the literature review of the most cited plants.MethodThe study included a survey part, plant identification and a review study. The first part was a cross-sectional descriptive study. Face to face questionnaires were distributed to 150 traditional healers and herbalist in all regions of the West Bank of Palestine. The literature review part was to assess the most cited plants for their efficacy and toxicity.ResultsOne hundred forty four herbalists and traditional healers accepted to participate in this study which was conducted between March and April, 2016. The results showed that 57 plant species belonging to 30 families were used by herbalists and traditional healers for treatment of various urinary tract diseases in Palestine. Of these, Apiaceae family was the most prevalent. Paronychia argentea, Plantago ovata, Punica granatum, Taraxacum syriacum, Morus alba and Foeniculum vulgare were the most commonly used plant species in the treatment of kidney stones, while Capsella bursa-pastoris, Ammi visnaga and Ammi majus were the most recommended species for treatment of urinary tract infections and Portulaca oleracea used for renal failure. In addition Curcuma longa and Crocus sativus were used for enuresis while Juglans regia, Quercus infectoria, Sambucus ebulus and Zea mays were used for treatment symptoms of benign prostate hyperplasia. Fruits were the most common parts used, and a decoction was the most commonly used method of preparation. Through literature review, it was found that Paronychia argentea has a low hemolytic effect and contains oxalic acid and nitrate. Therefore, it could be harmful to renal failure patients, also Juglans regia, Quercus infectoria and, Sambucus ebulus are harmful plants and cannot be used for treatment of any disease.ConclusionsOur data provided that ethnopharmacological flora in the West Bank regions of Palestine can be quite wealthy and diverse in the treatments of urinary tract diseases. Clinical trials and pharmacological tests are required evaluate safety and efficacy of these herbal remedies.

This study aims to use the tissues of Cyclamen persicum tubers to prepare activated carbon (CTAC) by different methods then to set up a thermodynamic study of the pharmaceutical diclofenac sodium (DCF) adsorption from aqueous solution onto this activated carbon. Optimum percent of DCF removal was 72% when CTAC dosage was 0.25 g and DCF concentration 50 mg/L. Percentage removal of DCF increases when the concentration of DCF increases as the maximum percentage removal reached 81% when DCF concentration was 70 mg/L and 0.7 g CTAC and pH ranging from 6 to 2.Freundlich model describes efficiently adsorption isotherm of DCF onto CTAC with n equal to 1.398 whose value indicates a favorable adsorption. This finding validates the assumption of multilayer physical adsorption process of DCF. The results showed that DCF was physically adsorbed onto CTAC, as confirmed by the values of DH°minor than 40 kJ/mol. As DG°had negative charge, the adsorption process is exothermic, and the adsorption process of the DCF onto CTAC is spontaneous, depending on temperature. ª 2014 The Authors.
