In this study pharmacists and pharmacy emplo yees, who work in 95 pharmacies in Malatya city center and accepted to join the study (n=203 ), filled a questionnaire which was prepared by using the literature. In the analysis of the obtained data, frequency and percentages were calculated by using SPSS 24.0 program. It was observed that 11.1 of the pharmacies were close to a health center and 88.0 of the participants were preparing magistral drugs. It was stated that 55.2 of the participants prepared magistral medications 1 2 times a week According to the results, although the frequency varied with the localization of pharmacies, magistral drug preparation ratios w ere generally similar with the literature. Preferred magistral drug forms were; cream (74.7 %%), pomade (69.8 and solution (54.7 in order.

There has been no previous investigation on the cytotoxicity of Delphinium formosum Boiss. & Huet. The extracts of the different parts of D. formosum, an endemic species in Turkey, were investigated for their cytotoxic activity against the human liver carcinoma cell line (HepG2) and primary human umbilical vein endothelial cells (HUVEC). The cytotoxic effects of twelve extracts and subfractions were determined against HepG2 cells using MTT assay. The only active extract was applied to the HUVEC as a model for healthy cells. Only one of the alkaloid-containing extracts from the aerial parts was toxic (IC50 = 244,9 μg/mL against HepG2 and 144,4 μg/mL against HUVEC), while the root extracts were inactive. The results were improbable although it’s predicted secondary metabolites, such as diterpene alkaloids (methyllycaconitine, browniine, lycoctonine, avardharidine, antranoyllycoctonine, delsemine A/B and lycoctonine). Based on previous studies in literature, the cytotoxic plants were also expected to exhibit insecticidal activity. Therefore, the cytotoxic extract of D. formosum was examined for its adulticidal and larvicidal activity against the yellow fever, dengue fevers and Zika virus vector Aedes aegypti L.

In this study, it was aimed to screen and understand critical formulation and process parameters inthe preparationflurbiprofen and paclitaxel co-loaded nanoparticles for developing an anti-cancer nano co-delivery system. With this aim, critical parameters were determined using Plackett–Burman experimental design (DoE). Flurbiprofen and paclitaxel drug loading amounts were considered as critical quality attributes to controleffective drug loading ratio. Furthermore, average particle size and zeta potential were also defined as critical quality attributes in order to optimize passive drug targeting and colloidal stability. Surfactant type was determined as the most significant factors for the average particle size and zeta potential. For flurbiprofen and paclitaxel drug loading into the nanoparticles, amounts of both flurbiprofen and paclitaxel were determined as critical factors. Consequently, paclitaxel and flurbiprofen were efficiently loaded into nanoparticles and the impact of the formulation variables were successfully screened by a DoE. By controlling the determined parameters, therapeutic efficacy of co-loaded drug nanoparticles could be maximized in further studies.

Rheum ribes is consumed as food and widely used in folk medicine against nausea, constipation and for different diseases including diabetesand hypertension. Unfortunately, the researches on Rheum ribes toxicity are insufficient. In our study, human hepatocellular carcinoma (HepG2) cell line was used in cytotoxicity evaluation of Rheum ribes water, methanol and chloroform extracts by MTT and NRU test. Comet assay was used to investigate the genotoxicity potentials of the plant extracts. Our results show that all extracts cause cell death in a concentration dependent manner at 5-50 mg/mL concentrations. The IC50 values are 14.29- 31.94 mg/mL by MTT and 21.15 - 27.66 mg/mL by NRU assay. The highest concentration (25 mg/mL) of methanol extract causes a significant DNA damage (8.7-folds). In conclusion, similar to a lot of plants used in the folk medicine the risk of Rheum ribes is still unknown. The uncontrolled use of this plant could harm to the patients. Our results indicate possible cyto- and gentoxicity effects of Rheum ribes, these results should rise the concerns about the safety of Rheum ribes and other folk herbs.

Concurrently, increasing numbers of studies revealing their potential toxic effects and possible toxicity mechanisms are ongoing. In this study, we assessed the toxic potentials of Bi2O3-NPs in human SH-SY5Y neuroblastoma cell line. After Bi2O3-NPs characterization using TEM, the cytotoxic potentials were evaluated by MTT and LDH assays. The induction of reactive oxygen species production was evaluated by H2DCFDA. In order to evaluate the oxidative damages, the changes in antioxidant catalase and superoxide dismutase and glutathione levels were determined. The cellular death pathway and the role of immune response were studied by measuring the mRNA expression levels of related genes. Our results showed that Bi2O3-NPs decreased the cell viability through disruption on mitochondrial activity (IC50:77.57 μg/mL) and membrane integrity (LDH%50:16.97 μg/mL). At 50 μg/mL Bi2O3-NPs, the production of reactive oxygen species (ROS) was induced significantly as well as the catalase and superoxide dismutase levels. In immune response, the mRNA expression levels of interleukin (IL)-6 were increased more than 1.5-fold in all doses; whereas, TNF-α, NF-ĸB and MAPK8 expressions were remained unchanged. Consequently, Bi2O3-NPs induced oxidative stress-related inflammation via activation of pro-inflammatory cytokine, IL-6.

The antioxidant (free radical scavenging, reducing power, β-carotene/linoleic acid, and phosphomolybdenum) and metal chelation properties were also investigated. The methanol extracts of C. cilicica vigorously inhibited the activities of acetylcholinesterase and butyrylcholinesterase (1.33 and 0.68 mg galantamine equivalents (GALAE)/g extract, respectively). It was observed that C. cilicica extracts possessed a higher inhibitory potential for α-glucosidase (2.71–1.23 mmol acarbose equivalents (ACAE)/g extract) than that for α-amylase (0.57–0.12 mmol ACAE/g extract). The water extract of C. cilicica showed potent radical scavenging capacity against DPPH (2, 2-diphenyl-1-picrylhydrazyl) and ABTS (2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (42.46 and 57.70 mg trolox equivalents (TE)/g extract, respectively). Phytochemical determination showed that C. cilicica water extract (17.26 mg rutin equivalents (RE)/g extract) was rich in flavonoids compared with ethyl acetate and methanol extracts (2.78 and 2.83 mg RE/g extract, for the respective extracts). These findings reveal the interesting potential of C. cilicica as a valuable source of phytochemicals that can be used against common noncommunicable diseases, particularly against enzymes involved in neurodegenerative diseases.","PeriodicalId":14484,"journal":{"name":"İstanbul Journal of Pharmacy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72608473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
