<P></P> <P>This report presents the comparison philosophy, methodology, analysis and the results of the designed CCM.D-K4 key comparison that covered the calibration of high resolution hydrometers for liquid and alcoholometers in the density range 600 kg/m<SUP>3</SUP> to 2000 kg/m<SUP>3</SUP> at the temperature of 20°C. The main purpose of this comparison was not only to evaluate the degree of equivalence in the calibration of high accuracy hydrometers between NMI participants, but also to link, were it is possible, the results of previous comparisons to Key Comparison Reference Values (KCRVs) of CCM.D-K4. Eleven NMI laboratories took part in the CCM.D-K4 divided in two groups (petals).</P> <P>With the CCM.D-K4 purpose, two similar sets consisting of three hydrometers for liquid density determinations and an alcoholometer were circulated to the NMI participants as a travelling standard in the time interval from January 2011 to April 2012.</P> <P>Twelve Key Comparison Reference Values (KCRVs) for each petal have been obtained at the density values related to the tested density marks of the transfer standards by the results of participants. The KCRVs and corresponding uncertainties were calculated by the weighted mean in the case of consistent results, otherwise the median was used.</P> <P>The degree of equivalence (DoE) with respect to the corresponding KCRV was determined for each participant and, in this particular comparison, the Weighted Least Squares (WLS) method was used to link the individual DoE of each participant by a continuous function.</P> <P>Significant drift of the transfer standards was not detected.</P> <P>This report also gives instructions on calculating pair-wise degrees of equivalence, with the addition of any information on correlations that may be necessary to estimate more accurately as well as the procedure for linking international comparisons to the CCM.D-K4. Finally an example of linkage to the CCM.D-K4 is given by dealing with the results of the bilateral comparison between INRiM and NMIA, which was added to this comparison so that all participants were engaged after the breakage of the 9340171 artefact.</P> <P>A particularly good agreement was found among the results provided by most of the participants, even if some systematic differences and either underestimated or overestimated uncertainties of the submitted results can be identified with respect to the KCRVs. In general the deviations of the laboratory results to the KCRVs are within of 1/3rd to 1/4th of a scale division and the uncertainty at 95% is usually within half a division. During the analysis of the submitted results, a systematic difference between the first and last immersed mark was also noted, possibly due to a temperature gradient along the stem and/or wetting of the stem around the tested mark, and therefore a corrected claimed uncertainty from each laboratory is expected. However this comparison may help the laboratories to solve some residual or marginal problems as well as to better understand the uncertainty components.</P> <P>The comparison fully supports the calibration measurement capabilities table in the BIPM key comparison database (KCDB). The results can be used to link regional comparisons to this CCM key comparison</P> <H2>Main text</H2> <P> To reach the main text of this paper, click on <A HREF='http://www.bipm.org/utils/common/pdf/final_reports/M/D-K4/CCM.D-K4_Final_Report.pdf'>Final Report</A>.

Cenostigma macrophyllum Tul. var. acuminata Teles Freire (Leguminosae–Caesalpinioideae) is a medicinal plant traditionally used for treatment of gastric ulcer. This study evaluated the ulcer-healing activity of the hydroalcoholic fraction of C. macrophyllum Tul. var. acuminata Teles Freire leaves (Cm-FHA) and the tea of the leaves of C. macrophyllum (Cm-tea), as well as the possible action of Cm-FHA, through in vitro models. Leaves of C. macrophyllum were dried and powdered to obtain the Cm-FHA. Subsequently, the Cm-FHA was characterized phytochemically and biologically. Besides, Cm-tea was prepared. The gastric healing effects of Cm-tea and Cm-FHA were analyzed using the model of acetic acid-induced gastric ulcer in rats. The human gastric adenocarcinoma (AGS) cell line was employed as an in vitro model. Cm-tea promoted a protective effect against gastric ulcers induced by absolute ethanol. Cm-FHA or Cm-tea (100 mg/kg/7 days) exhibited a significant healing effect on ulcers induced by acetic acid. In the histological analysis, gastric mucosa treated with Cm-FHA or Cm-tea advanced restoration of the mucosal epithelium. In vitro, lower concentrations of Cm-FHA stimulated cell proliferation in the BrdU assay and cell migration. Cm-tea and Cm-FHA present a significant gastric healing effect in in vivo and in vitro models.

This study was conducted to evaluate the effect of inclusion of propolis extraction residue in the feed of broilers from 1 to 21 d of age on phagocytic activity of macrophages, cutaneous basophil hypersensitivity response to phytohemagglutinin, antibody production against Newcastle disease, lymphoid organ weight and hematological profile and to determine the optimal level of inclusion. 120 chicks, reared in metabolism cages until 21 days of age, were distributed in a completely randomized design, with five treatments (0%, 1%, 2%, 3%, and 4% of propolis residue) and six replications. The relative weight of thymus and monocyte percentage were affected by propolis residue, with a quadratic response (p<0.05) and lowest values estimated at 2.38% and 2.49%, respectively. Changes in relative weight of cloacal bursa and spleen, percentage of lymphocyte, heterophil, basophil, eosinophil, and heterophil:lymphocyte ratio, antibody production against Newcastle disease, phagocytic activity of macrophages and the average number of phagocytosed erythrocytes were not observed. The nitric oxide production with regard to positive control (macrophages+erythrocytes) decreased linearly (p<0.05) with increased doses of propolis residue. The remaining variables of nitric oxide production (negative control – macrophages, and difference between the controls) were not affected by propolis residue. The cutaneous basophil hypersensitivity response to phytohemagglutinin as determined by the increase in interdigital skin thickness exhibited a quadratic response (p<0.05), which predicted a lower reaction response at a dose of 2.60% of propolis residue and highest reaction response after 43.05 hours of phytohemagglutinin injection. The inclusion of 1% to 4% of propolis extraction residue in broiler diets from 1 to 21 days of age was not able to improve the immune parameters, despite the modest changes in the relative weight in thymus, blood monocyte percentage, nitric oxide concentration, and interdigital reaction to phytohemagglutinin.

Santos, A.B.,Pereira, M.L.A.,Silva, H.G.O.,Pedreira, M.S.,Carvalho, G.G.P.,Ribeiro, L.S.O.,Almeida, P.J.P.,Pereira, T.C.J.,Moreira, J.V. Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.5

This study aimed to evaluate urea excretion, nitrogen balance and microbial protein synthesis in lactating goats fed with diets containing different protein sources in the concentrate (soybean meal, cottonseed meal, aerial part of cassava hay and leucaena hay). Four Alpine goats whose mean body weight was $42.6{\pm}6.1kg$ at the beginning of the experiment, a mean lactation period of $94.0{\pm}9.0days$ and a production of $1.7{\pm}0.4kg$ of milk were distributed in a $4{\times}4$ Latin square with four periods of 15 days. Diets were formulated to be isonitrogenous, containing 103.0 g/kg of CP, 400 g/kg of Tifton 85 hay and 600 g/kg of concentrate. Diet containing cottonseed meal provided (p<0.05) increased excretion of urea and urea nitrogen in the urine (g/d and mg/kg of BW) when compared with leucaena hay. The diets affected the concentrations of urea nitrogen in plasma (p<0.05) and excretion of urea nitrogen in milk, being that soybean meal and cottonseed meal showed (p<0.05) higher than the average aerial part of the cassava hay. The use of diets with cottonseed meal as protein source in the concentrate in feeding of lactating goats provides greater nitrogen excretion in urine and negative nitrogen balance, while the concentrate with leucaena hay as a source of protein, provides greater ruminal microbial protein synthesis.

Impacts of Human Induced Activities on Species Composition and Diversity in Miombo Woodlands of Bagamoyo District, Tanzania

Dos Santos A Silayo,M.C.T. Tarimo,Amini R.E. Kweka,Muganda A. Michael 한국외국어대학교 아프리카연구소 2006 Asian Journal of African Studies Vol.20 No.-

The Miombo woodlands in Bagamoyo district are among the richestplant community stands in Eastern Tanzania that is subjected to a serious human induced activities like of charcoal production, farming and grazing. We investigated on the ecological impacts of these activities on species diversity and composition. The study was conducted in Mbwewe general land forest and Uzigua forest reserve in Bagamoyo District, Coastal Region, Tanzania. These forests differ in both management and utilization regimes. We adopted a systematic sampling design for which, 48 sample plots; 30 plots in the public forest and 18 plots in the reserved forest were laid out for data collection. The number of plots for the general land forest was higher due its bigger size, vegetation heterogeneity and diverse human activities. About 81% tree and 19% shrubs of 59 different species were recorded. Acacia polyacantha sub species campylacantha and Brachystegia boehmiiwere dominant species in the general land and reserved forest respectively. Stand parameters; number of stems, basal area and wood volume per ha were higher in the reserved forest. Distribution of stem numbers by size class show reversed J-shape trend in both forest types, indicating active growth of the woodland while, wood volume and basal area per ha showed normal distribution. The Shannon - winner indexes of diversity were 2.86 and 2.5 while the indices of dominance were 0.08 and 0.11 indicating higher species diversity in the forest reserve. The loss of woodland species especially on the general land will continue with associated consequences if appropriate plant utilization and land use management practices are not carried out. We therefore recommend intensive law enforcement and community education. The government should also consider subsidizing electricity costs to make it 'affordable' so as to reduce high level of charcoal demand at the national level which was observed to be the main reason for tree cuts.

Kefir is an association of microrganisms generally grown in milk, with known probiotic activities identifiedfrom its soured suspensions. Aqueous media are also able to grow kefir, but little is known about the probiotic properties ofits fermented products. This work aimed to evaluate some probiotic properties of a carbohydrate fraction isolated from sug-ary kefir (sugary kefir carbohydrate [SKC]). Anti-inflammatory activity of the isolated fraction of carbohydrate was testedboth in vitro(cellular respirometry and macrophage culture) and in vivo (50% effective dose, rat paw edema, vascular per-meability, and cicatrizing test). The results indicated no significant difference for oxygen uptake or macrophage culture be-tween control and test groups. Rat paw edema, however, showed a significant inhibitory activity by 30. 4% and 54 . 8%(P. .001) for carrageenan and dextran, respectively. In the cicatrizing test, animals treated with SKC cream also presentedless trauma after treatments as compared to the negative control group (P. .05). The overall data suggested the SKC as anatural product that could be used as a constituent of an anti-inflammatory compound.

FREEZING POINT DEPRESSION OF RAW GOAT'S MILK FROM THE REGION OF GOIÂNIA, BRAZIL

de Sousa, J.T.,Dias, M.J.,Tanezini, C.A.,D'Alessandro, W.T.,de Olineira, B.C.,de Melo Rocha, J.,dos Santos Pontes, I. Asian Australasian Association of Animal Productio 1993 Animal Bioscience Vol.6 No.4

Studies at freezing point depression (FPD) for goat milk are described in this paper. The 432 samples of raw goat milk collected in a period of two years and analysed by the use of an electronic cryoscope gave a mean value of FPD: $-0.565{\pm}0.01^{\circ}C$. Statistical significant differences were found between the morning and evening milk. The evening milk showed better quality considering the lactose and others dissolved solutes. Among the Brown, Saanen and Anglo-nubian goats, the greatest increase in FPD, occurred in the Anglo-nubian breed. The statistical analysis revealed a significant breed difference (p<0.05), when climate variation was observed. The superior and inferior values found to the FPD of the caprine milk (-0.545 to $-0.585^{\circ}C$), is important in establishing regional rules, to improve the quality control criteria and legal interpretation of standards found in the pertinent legislation. The results are also important to improve herd management so that one can increase the animal production which will affect the technological composition, and the nutritional characteristics of the resultant products.
