PERBEDAAN EFEK ANTHELMINTIK ANTARA PERASAN BIJI PEPAYA MUDA DAN PERASAN BIJI PEPAYA YANG SUDAH MASAK (Carica papaya Linn.}TERHADAP MORTALITAS CACING Ascaris suum SECARA IN VITRO
Get PDF"Perbedaan efektifitas an tara perasan biji pepaya muda dan perasan biji
pepaya masak dipengaruhi oleh perbedaan aktifitas enzim glukosida dan alkaloid
karpain yang terdapat diantara keduanya. Penelitian ini bertujuan untuk mencari
dan menentukan besamya perbandingan efektifitas kedua jenis perasan terhadap
mortalitas cacing Ascaris suum. Percobaan dilakukan secara in vitro dengan
merendam cacing dalam larutan yang berisi perasan biji pepaya dengan berbagai
konsentrasi. Hasil penelitian secara umum menunjukkan peningkatan jumlah
cacing yang mati (paralisis) pada setiap perlakuan seiring dengan lamanya waktu
perlakuan. Hasil terbaik didapat dari perasan biji pepaya muda dengan kadar 30%
v/v dengan prosentase jllmlah kematian cacing sebesar 74 % selama 24 jam. Dari
hasil penelitian dapat disimpulkan bahwa perasan biji pepaya muda mempllnyai
efek anthelmintik dua kali lebih besar daripada perasan biji pepaya yang sudah
masak.
Efektifitas Biji Pepaya dalam membunuh Ascaris suum : uji in-vitro
No full textThere are many medicine plants have been consumed by community as a traditional medicine and believed empirically as anthelmintic since long time ago, such as papaya (Carica papaya Linn.). This article compared anthelmintic affectivity between raw papaya seeds and ripe papaya seeds against Ascaris suum in vitro. Research was conducted in Parasitology laboratory of Veterinary Medicine, Airlangga University on June-August 2002. Ten worms were put into chamber of treatment respectively 10%, 20%, 30% raw papaya seed; ripe papaya seeds in the same concentrations; pipperazine sitrate 0,2% and NaCl 0,9% and incubated in 370C then observed paralyzed or died worms every 3, 6, 12, and 24-hour. Probit Analysis was used to determine LC50 and LT50 value. The results showed that raw papaya seeds were more effective than ripe papaya seeds and piperasin sitrat based on the time needed to kill 50% Ascaris suum (LC50=14,36167% and LT50=18,97687%).</p
HUBUNGAN ANTARA INFEKSI CACING DAN ATOPI PADA MURID SDN KAMPUNG BARU, KECAMATAN KUSAN HILIR KABUPATEN TANAH BUMBU KALIMANTAN SELATAN TAHUN 2011
Get PDFHelminth infection is an important public health problem. Millions of people are infected with more than one type of intestinal worms such as mixed infection of hookworms, roundworms, and pinworms. Worm infections are generally associated with immune response often leads to clinical manifestations of the so called type-1 hypersensitivity (atopic allergy). However, populations exposed to helminth infections showed less symptoms of allergies. The aim of this study wanted to know the association between atopic allergy and worm diseases in primary school children so that if an allergy test cannot detect the presence of a reaction to certain allergens, it can be considered for examination on worm infection. This was an analytic observational study using cross sectional design approaches (cross-sectional). The sample selection is done by cluster sampling method was chosen for the pupil at Elementary School grade 3 to grade 6 are distributed pot for their feces, feces to be examined for the presence of worm eggs. Interviews were also conducted on parents / guardians of students of research subjects to determine the status of allergy in children by using standardized questionnaires that is called ISSAC. 84 students grades 3-6 which returns a pot that contains feces, a total of 26 children (31%) infected worms. Serum from 84 children who successfully checked by ELISA, there were 37 children (44%) who had atopy. The statistical test showed no significant association between worm T.trichiura infections and or A.lumbricoides and or Hookworm in children with atopic status (p = 0.353, C = 0.126). No association may caused by the distribution of both diseases do not overlapped
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
