Abstract

Secara empiris biji alpukat dan biji pepaya digunakan sebagai antidiabetes. Penelitian ini bertujuan untuk menentukan konsentrasi yang efektif terhadap penurunan kadar glukosa darah tikus putih (Rattus norvegicus) dari kombinasi infusa biji alpukat  dan biji pepaya varietas Bangkok. Penelitian ini menggunakan 24 ekor tikus yang dibagi dalam 8 kelompok yaitu 2 kelompok kontrol (normal dan negatif), 2 kelompok perlakuan yang diberikan infus biji alpukat dan biji pepaya, 3 kelompok perlakuan yang diberikan kombinasi infus biji alpukat dan biji pepaya konsentrasi 0,4% v/v, 0,6% v/v, dan 0,8% v/v, dan 1 kelompok pembanding yang diberikan glibenklamid. Semua kelompok perlakuan diberikan sediaan uji secara oral selama 14 hari. Sebelum perlakuan tikus terlebih dahulu diinduksi dengan aloksan 120 mg/kgBB secara intraperitonial. Pengukuran kadar glukosa darah dilakukan pada hari ke -1, -3, -7, -11, dan -14. Hasil penelitian menunjukkan bahwa kombinasi infus biji pepaya dan biji alpukat konsentrasi 0,4% v/v, 0,6% v/v , dan 0,8% v/v memberikan efek dalam menurunkan kadar glukosa darah  dan konsentrasi yang paling efektif dalam menurunkan kadar glukosa darah adalah konsentrasi 0,6% v/v.

Abstract

This study was a descriptive research (non-experiment) that aims to describe the details of study area and various mushrooms characteristic that classify Basidiomycota by literature identification. The study area was Lembanna Village of Tinggi Moncong district, Bawakaraeng Mount in Gowa Regency. The base on area selection in pre-study that was Lembanna Village in Bawakaraeng Mount was one of the areas that have the high mushrooms diversity.  This study was going in April 2011. The technique of collected data by explores an area to straight saw the mushrooms in their location. The exploration in 07.00 a.m until 16.00 p.m. The data collected were characteristic of mushrooms morphology, the condition of mushrooms when their found, and documentation by took the detail picture to identification interests. The analysis data in qualitative that depend on characteristic of mushrooms morphology in classify basidiomycota and made identification as well classification of mushrooms that found in area studied that depend on resemblance anaylzed with literature of basidiomycota Classis. The resulted of study showed that there were mushrooms basidiomycota classis in Lembanna Village area of Tinggi Moncong district, Bawakaraeng Mount in Gowa Regency. The number of mushrooms were eight (8) that could be discriminate in 2 Subclassis, i.e: Holobasidiomycetidae in Polyporales Ordo that is Ganoderma applanatum, Polyporus arcularius, Polyporus squamosus, Grifola frondosa, Piptoporous betulinus and Russulales Ordo that is  Stereum hirsutum, Stereum ostrea, and  Heterobasidiomycetidae in Auriculariales Ordo that is Auricularia auricula.  So, the conclution of this research, there were several of basidiomycota mushrooms that found in the area studied but not too much.  However, dominate of various in the area studies was Polyporales Ordo.

Abstract

Abtract. This study was aimed at studying changes in the morphology of Salmonella enteritidis bacterial cells after the crude extract of Pheretima sp. using a scanning electron microscope (SEM). Earthworm extraction uses 96% ethanol, and binds to the appropriate bacteria in the exponential phase with extract concentrations of 5% and 10%. Observations using a microscope scanner were carried out after agreeing to a 6-hour, 12-hour, and 24-hour extract. Obtained from the results showing the crude extract of Pheretima sp. to changes in cell morphology of Salmonella enteritidis bacteria. Salmonella enteritidis bacterial cells are damaged consisting of: formed holes in the surface of bacterial cells, bumps on the surface of bacterial cells, shrinkage of bacterial cells, elongation of bacterial cells, and increase in bacterial cells. In addition, as well as longer contributions and free time, incubation, after being added, crude extract of Pheretima sp. against Salmonella enteritidis bacteria, the greater the damage caused. However, 5% extract concentration is the optimal concentration in the effect of damage to the morphology of the cells of Salmonella enteritidis bacteria.Keywords: Coarse Extract, Earthworms, Pheretima sp., Morphological Cells, Salmonella enteritidis, Scanning Electron Microscope (SEM).

Abstract

Resistensi obat anti-malaria harus diantisipasi secara dini karena belum ada obat yang dapat menggantikan terapi lini pertama terkini, Artemisinin based combination therapy (ACT). Karena itu organisasi kesehatan dunia WHO menetapkan beberapa langkah untuk menghindari atau mengatasi munculnya parasit Plasmodium yang resisten terhadap obat tersebut. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang meningkatkan resiko timbulnya resistensi parasit di daerah endemik malaria di Kecamatan Tapalang, Sulawesi Barat. Delapan pasien positif malaria menjalani pengobatan dengan artesunat-amodiakuin (AS-AQ) selama 3 hari. Pasien di follow up selama masa pengobatan untuk melihat atau menanyakan efek samping obat yang dialami yang dapat mempengaruhi kepatuhan pasien terhadap prosedur pengobatan. Efek samping yang terbanyak adalah mual (50%), muntah (37.5%), lemas (25%) dan sakit kepala (25%). Selain itu dilakukan wawancara terhadap petugas kesehatan mengenai cara pemberian  AS-AQ. Dari wawancara diketahui bahwa AS-AQ biasanya diberikan dalam dosis terbagi dalam sehari, sehingga berpotensi menyebabkan dosis obat yang kurang optimal. Adanya potensi kurangnya kepatuhan pengobatan akibat efek samping obat yang mengganggu dan dosis obat yang kurang optimal merupakan faktor resiko resistensi terhadap ACT.

Abstract

 A research report of the composition of zooplankton species on Je’neberang river in Sungguminasa regency Somba Opu sub district. The objective of this research was to find out the composition of zooplankton species on Je’neberang river in Sungguminasa regency Somba Opu sub district. The sample was taken between 20.00-22.00 wita by using plankton net number 25 during thee days. The parameter used was biology, physics and chemistry parameters. This research employed descriptive method. It symbolized the composition of zooplankton species on Je’neberang river in Sungguminasa regency Somba Opu sub district on the three monitoring by using Sedgwick rafter method (SRC). It was monitored under binocular microscope.  The finding of the research showed that there were 26 species of zooplankton included Arthopod, Annelid, Asteroid, and Cnidaria filus. The Composition of zooplankton in the three monitoring was dominated by crustacean class. The abudance of zooplankton was 54 ind/m3.- 702 ind/m3. Based on the variety and dominan index, it can be concluded that Je’neberang river had the low variety of zooplankton.

Abstract

Abstract. Dengue hemorrhagic fever (DHF) is a disease caused by dengue virus infection. One symptom of dengue virus infection is high fever and headache. Dengue virus is a virus from the genus Flavivirus, family of Flaviviridae. This dengue fever is a dangerous viral disease because it can cause sufferers to die in a very short time / several days. The existence and population density are often associated with transmission, endemicity and Extraordinary Events (EE) of DHF. Disease mapping by utilizing digital technology to support epidemiological investigations and also as a tool to monitor regional conditions for dengue disease. The purpose of this study was to determine efforts to prevent and control dengue disease by mapping. The results of the study show that mapping can be seen as increasing and decreasing the number of cases of dengue disease so that it can assist in data management and reporting of information to monitor areas at risk of contracting dengue disease. Suggestions given need to do further research using other variables that are the cause of the high rate of dengue cases, so that it can be utilized by related agencies as the basis of the information system supporting the decision on preventive measures to combat dengue. Keywords: prevention and control, DHF, mapping.
