Ashour, "Antimicrobial resistance pattern and their beta-lactamase encoding genes among Pseudomonas aeruginosa strains isolated from cancer patients.", BioMed research international, vol. 2014, pp. 101635, 2014. Abstract

This study was designed to investigate the prevalence of metallo-β-lactamases (MBL) and extended-spectrum β -lactamases (ESBL) in P. aeruginosa isolates collected from two different hospitals in Cairo, Egypt. Antibiotic susceptibility testing and phenotypic screening for ESBLs and MBLs were performed on 122 P. aeruginosa isolates collected in the period from January 2011 to March 2012. MICs were determined. ESBLs and MBLs genes were sought by PCR. The resistant rate to imipenem was 39.34%. The resistance rates for P. aeruginosa to cefuroxime, cefoperazone, ceftazidime, aztreonam, and piperacillin/tazobactam were 87.7%, 80.3%, 60.6%, 45.1%, and 25.4%, respectively. Out of 122 P. aeruginosa, 27% and 7.4% were MBL and ESBL, respectively. The prevalence of bla(VIM-2), bla(OXA-10(-)), bla(VEB-1), bla(NDM(-)), and bla(IMP-1)-like genes were found in 58.3%, 41.7%, 10.4%, 4.2%, and 2.1%, respectively. GIM-, SPM-, SIM-, and OXA-2-like genes were not detected in this study. OXA-10-like gene was concomitant with VIM-2 and/or VEB. Twelve isolates harbored both OXA-10 and VIM-2; two isolates carried both OXA-10 and VEB. Only one strain contained OXA-10, VIM-2, and VEB. In conclusion, bla(VIM-2)- and bla(OXA-10)-like genes were the most prevalent genes in P. aeruginosa in Egypt. To our knowledge, this is the first report of bla(VIM-2), bla(IMP-1), bla(NDM), and bla(OXA-10) in P. aeruginosa in Egypt.

Öztürk, "Antihyperglycemic and Antihyperlipidemic Effects of Ferula assa-foetida and Ferula tenuissima Extracts in Diabetic Rats", Pakistan Journal of Biological Sciences, vol. 18, no. 7: Asian Network for Scientific Information (ANSINET), pp. 314, 2015. Abstract

The present study was carried to explore the potential antihyperglycemic and antihyperlipidemic activity of Ferula assa-foetida L. and Ferula tenuissima Hub-Mor & Pesmen extracts in streptozotocin (STZ) induced diabetic rats. Furthermore, phytochemical screening, in vitro antioxidant activity and acute toxicity study of both plants were performed. Both extracts showed considerable antioxidant potential in vitro. In diabetic rats, F. assa-foetida (200 and 400 mg/kg) and F. tenuissima (400 mg/kg) showed significant elevation in plasma insulin level, total hemoglobin (Hb) and decrease in Fasting Blood Glucose (FBG) and glycosylated hemoglobin (HbA1c) levels. Significant elevations in the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and level of reduced glutathione (GSH) in liver and pancreas homogenates were observed in diabetic animals following F. assa-foetida (200 and 400 mg kgG1) and F. tenuissima (400 mg kgG1) treatments. The antihyperlipidemic effect of F. assa-foetida extract was demonstrated by a significant reduction in plasma triglycerides (TG), Total Cholesterol (TC), Low Density Lipoprotein Cholesterol (LDL-C) and the increase of High Density Lipoprotein Cholesterol (HDL-C). Plasma activities of alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) and levels of Total Protein (TP) and bilirubin (BIL) in diabetic rats were recovered significantly after F. assa-foetida and F. tenuissima treatment in comparison with diabetic controls. The present data suggest that F. assa-foetida have both antihyperglycemic and antihyperlipidemic effects with enhancement of insulin-secreting activity.

Yusufoglu, H. S., G. A. Soliman, R. F. Abdel-Rahman, and M. S. Abdel-Kader, "Antioxidant and Antihyperglycemic Effects of Ferula drudeana and Ferula huber-morathii in Experimental Diabetic Rats", International Journal of Pharmacology, vol. 11, issue 7, pp. 738-748, 2015. Abstract

In the present study, DPPH radical scavenging assay and ferric-reducing antioxidant assay were used to estimate the potential in vitro antioxidant effect of the methanol extracts of Ferula drudeana Korovin (F. drudeana) and Ferula huber-morathii Peşmen (F. huber-morathii). The antidiabetic activity of both extracts was evaluated in streptozotocin (STZ)-induced diabetic rats. Glibenclamide was taken as the standard drug. Both extracts showed considerable antioxidant potential in the DPPH radical scavenging assay and minimum reducing power in ferric-reducing antioxidant assay. Oral administration of F. drudeana (400 mg/kg) and F. huber-morathii (200 and 400 mg/kg) extracts to diabetic rats produced a marked reduction in Fasting Blood Glucose (FBG) and elevation in insulin levels after 14 and 28 days of treatment. A meaningful reduction in the concentrations of glycosylated hemoglobin (HbA1c), triglycerides (TG), Total Cholesterol (TC), Low Density Lipoprotein (LDL) in plasma and elevations in the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and glutathione (GSH) in liver and pancreas homogenates were observed in diabetic animals medicated with F. drudeana (200 and 400 mg kgG1) and F. huber-morathii (400 mg kgG1) extracts. Levels of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), bilirubin, total protein and High Density Lipoprotein (HDL) in plasma and malondialdehyde (MDA) in liver and pancreas homogenates were recovered significantly in F. drudeana and F. huber-morathii-medicated diabetic rats. Besides, biochemical results were supported by histopathological findings. These findings showed the significant antioxidant and hypoglycemic activities of F. drudeana and F. huber-morathii extracts in diabetic rats.

Yusufoglu, H. S., G. A. Soliman, R. F. Abdel-Rahman, and M. S. Abdel-Kader, "Antihyperglycemic and Antihyperlipidemic Effects of Ferula duranii in Experimental Type 2 Diabetic Rats", International Journal of Pharmacology, vol. 11, issue 6, pp. 532-541, 2015. Abstract

In the present study, DPPH radical scavenging assay and ferric-reducing antioxidant assay were used to evaluate in vitro antioxidant potential of the methanol extract of Ferula duranii (F. duranii). The antihyperglycemic and antihyperlipidemic activities of F. duranii extract were evaluated in streptozotocin (STZ)-induced diabetic rats. F. duranii showed considerable antioxidant potential in the DPPH radical scavenging assay and minimum reducing power in ferric-reducing antioxidant power assay. A meaningful reduction in the concentrations of Fasting Blood Glucose (FBG), glycosylated hemoglobin (Hb A1c), triglycerides (TG), Total Cholesterol (TC) and Low Density Lipoprotein (LDL-C) in plasma and an elevation in the activity of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) in hepatic and pancreas homogenates were observed in diabetic animals medicated with F. duranii extract in comparison with diabetic control rats. The level of insulin raised significantly in plasma of diabetic groups received F. duranii in respect to diabetic control one. Levels of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), bilirubin, total protein and High Density Lipoprotein (HDL-C) in plasma and malondialdehyde (MDA) in liver and pancreas homogenates were recovered significantly in F. duranii-medicated diabetic rats in comparison with diabetic controls. The present data suggest that F. duranii has both antidiabetic and antihyperlipidemic effects.
