        Effect of Honey on Serum Cholesterol and Lipid Values

        Karsten Münstedt,Sven Hoffmann,Annette Hauenschild,Michael Bülte,Richard von Georgi,Andreas Hackethal 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.3

        Small studies have suggested that honey benefits patients with high cholesterol concentrations. The present study aimed to confirm this finding in a larger group of subjects. Sixty volunteers with high cholesterol, stratified according to gender and hydroxymethylglutaryl-coenzyme A reductase inhibitor (statin) treatment (yes/no), were randomized to receive 75g of honey solution or a honey-comparable sugar solution once daily over a period of 14 days. Baseline measurements, including body mass index (BMI) and lipid profile, were obtained, and subjects also completed dietary questionnaires and the Inventory for the Assessment of Negative Bodily Affect–Trait form (INKA-h) questionnaire. Measurements were repeated 2 weeks later. BMI and high-density lipoprotein (HDL) cholesterol values were significantly correlated (r=−0.487; P<.001) as were BMI and a lower ratio of low-density lipoprotein (LDL) cholesterol to HDL cholesterol (r=0.420; P<.001), meaning that subjects with a high BMI had a lower HDL cholesterol value. INKA-h scores and LDL cholesterol values were also significantly correlated (r=0.273, P=.042). Neither solution influenced significantly cholesterol or triglyceride values in the total group; in women, however, the LDL cholesterol value increased in the sugar solution subgroup but not in the women taking honey. Although ingesting honey did not reduce LDL cholesterol values in general, women may benefit from substituting honey for sugar in their diet. Reducing the BMI lowers the LDL cholesterol value, and psychological interventions also seem important and merit further investigation.

        Evaluation of Three Molecular Methods of Repetitive Element Loci for Differentiation of Mycobacterium avium subsp. paratuberculosis (MAP)

        Amr El-Sayed,Abdulwahed Ahmed Hassan,Saleh Natour,Amir Abdulmawjood,Michael Bülte,Wilfried Wolter,Michael Zschöck 한국미생물학회 2009 The journal of microbiology Vol.47 No.3

        The aim of the present study is to evaluate the efficiency of three methods to determine the molecular diversity of 34 Mycobacterium avium subsp. paratuberculosis (MAP) strains isolated from 17 cattle herds. The applied methods included the analysis of sequence polymorphism of the mononucleotide (G1 and G2) and trinucleotide sequences (GGT) of the Short Sequence Repeats (SSR) and the determination of size polymorphism of 9 different Mycobacterial Interspersed Repetitive Units (MIRU) and 6 Variable Number Tandem Repeats (VNTR). Sequence analysis of SSR of 34 isolates showed 4, 6, and 2 alleles of G1, G2, and GGT repeats, respectively. The amplification of the investigated 9 MIRU units revealed only two discriminatory genotyping systems (MIRU2 and MIRU3). Out of 6 VNTR PCR differentiation methods, only one method could be recommended for genotyping purposes. The profile 7g-12g-4ggt-II-b-2 of the combination systems G1-G2-GGT-MIRU2-MIRU3-VNTR1658 dominates among the examined isolates and was detected in 14.7% of the isolates. The use of certain repetitive loci of SSR, MIRU, and VNTR techniques in this study showed greater potential than others for the characterization of MAP isolates. The recommended loci can be used for the epidemiological tracing of MAP field strains and to determine the relationships between isolates in different herds.
