Abstract

HER2 (Human Epidermal Growth Factor Receptor 2) merupakan suatu reseptor pada permukaan sel yang berpengaruh pada proliferasi jaringan, mutasinya dapat menjadi onkogen. Over ekspresi dari HER2 pada kasus kanker dapat dilihat dengan teknik imunohistokimia (IHC). Protein blocking merupakan salah satu langkah dalam pengecatan IHC yang berfungsi menghalangi ikatan non spesifik pada jaringan dengan menggunakan normal serum dan protein solution (susu skim). Tujuan penelitian mengetahui gambaran hasil pengecatan IHC menggunakan normal serum dan susu skim. Penelitian secara eksperimental dengan pendekatan cross sectional. Sampel penelitian jaringan kanker payudara HER2 positif dengan stadium +2 dari satu organ dan pasien yang sama. Pengecatan IHC menggunakan teknik Strep (Avidin) Biotin Complex. Pengecatan menggunakan normal serum didapatkan hasil +2, menggunakan susu skim 1% didapatkan hasil +3, sedangkan menggunakan susu skim 2% dan 3% didapatkan hasil +2. Terdapat perbedaan yang signifikan antara normal serum dengan susu skim 1%. Tidak terdapat perbedaan yang signifikan antara normal serum dengan susu skim 2% dan susu skim 3%. Simpulan adalah normal serum dapat diganti dengan susu skim 2%.

Abstract

Minyak kelapa murni Virgin Coconut Oil (VCO ) merupakan minyak kelapa yang diproses tanpa pemanasan yaitu dengan penambahan enzim, pancingan, sentrifugasi.  Minyak kelapa dari proses tersebut banyak mengandung asam lemak jenuh rantai sedang, yang diyakini sebagai herbal alternative untuk pengobatan dan pencegahan penyakit degeneratif maupun penyakit yang disebabkan mikroorganisme. Kandungan vco yang paling banyak adalah asam lemak jenuh rantai sedang diantaranya : asam laurat, asam kaprilat, asam miristrat, asam palmirat dll yang mudah dicerna oleh tubuh menjadi energi yang siap dipakai. VCO juga diyakini sebagai obat keputihan yang disebabkan oleh jamur Candida albicans.  Penelitian ini dilakukan di Laboratorium Mikrobiologi Fakultas Ilmu Keperawatan dan Kesehatan UNIMUS pada bulan Mei sampai dengan Agustus 2007. Sampel berupa  Candida albicans isolate Semarang dan  VCO dari beberapa merk Penelitian dilakukan dengan  uji sensitifitas vco terhadap Candida albicans dengan metoda sumuran dan kandistatin ( antifungi ) sebagi control .Dari penelitian  ini memberikan hasil bahwa vco tidak dapat menghambat pertumbuhan Candida albicans secara invitro .    Kata kunci : Efektifitas, VCO, Kandidiasis

Abstract

Salmonella typhi is a negative basil Gram bacterium that causes typhoid fever. Flagel of S. typhi contain proteins, as locomotor and it can help bacteria to attach on host cells. Haemagglutinin protein is protein that can agglutinate erythrocytes. The goal of this research is to analize S. typhi flagellin proteins haemagglutination activity Based on ABO blood group. Flagellin proteins isolation method of modified Alexan method (2009) and haemagglutination test method of Finkeltein and Hanne method (1982). Haemagglutination result of ABO blood type show that SLT-1 S. typhi flagellin proteins can’t agglutinate human erythrocytes A, B, and O, but it can agglutinate human erythrocytes until 8 times dilution of AB blood type from 50 μg/μl concentration in 50 μl. BA 07.4 S. typhi flagellin proteins can agglutinate human erythrocytes of A blood type until 16 times dilution, 8 times dilution of AB blood type, 4 times dilution of O blood type, and it can’t agglutinate human erythrocytes B blood type.Keywords: Salmonella typhi, Flagellin Proteins, Haemagglutination, Erythrocytes of ABO System.

Abstract

This research aimed to study the use of cabbage extract as the source of lactic acid bacteria (LAB) onthe swelling power, solubility, amylose content, and organoleptic properties of mocaf. The researchwas carried out through two experimental steps with the first step aimed to study the optimumfermentation time based on swelling power of the mocaf. Whereas second step aimed to determine theoptimum cabbage extract concentration based on swelling power, solubility, amylose content, andorganoleptic properties. The results showed that optimum swelling power was achieved fromfermentation using 40% cabbage extract for 24 hours, optimum solubility was obtained using 60% and80% cabbage extracts, lowest amylose content was achieved by fermentation using 40% cabbageextract. The favored aroma, color and texture were obtained from fermentation using 20%, 40% and80% cabbage extract, respectively. The best fermentation condition was determined based on thelowest amylose content as low amylose means high amylopectin. Amylopectin plays important role intriggering the process of  puffing, by which food products will be light, porous, dry and crunchy.Mocaf with lowest amylose content is recommended as raw material for the manufacturing of cookies. Keywords: cabbage extract, lactic acid bacteria, mocaf, physicochemical properties, swelling power.

The objective of this research is to measure and analyze the difference of inhibition concentration of areca nuts concentration 2%b/v, 3%b/v, 4%b/v, 5%b/v and 6%b/v on the growth of S.aureus. The sample used in this research is areca nuts (Areca catechu L.) with the object of research S.aureus that has equalized turbidity with Mc Farland standard 0.5. Antibacterial testing is done by diffusion method (wells). The results showed that areca nuts can inhibit S.aureus bacteria with area of inhibit zone for concentration 2% b/v, 3% b/v, 4% b/v, 5% b/v and 6% b/v is 14,5 mm, 14,6 mm, 16 mm, 18 mm and 18 mm. Result of normality test Kolmogorov-Smirnov S.aureus (p=0,691) the values obtained are normally distributed. The homogenity test of S.aureus is not homogeneous, Then proceed with non parametric test that is Kruskal Wallis (p=1,000) the values obtained showed no significant difference to mean inhibition zone diameter between concentrations 2%b/v, 3%b/v, 4%b/v, 5%b/v and 6%b/v areca nuts infusion against S. aureus bacteria. Keywords: Areca nuts infusion, Staphylococcus aureus, Inhibition

Abstract

Ozone is one of the gases that can be used as a disinfectant to inhibit the growth of Escherichia coli bacteria. Time of exposure to ozone gas is a way used to disinfectEscherichia coli bacteria. The purpose of this study was to observe the number ofEscherichia coli bacteria exposed to ozone gas with exposure time of 5, 10, 15, 20, 25and 30 minutes and ozone gas control. The study sample was Escherichia colibacteria exposed to ozone gas. The results of the number of colonies of Escherichiacoli on CCA media after exposure to 5, 10, 15 minutes of ozone gas were mean 2.5 x106, 1.25 x 106, 0.5 x 106 CFU / ml, and 20, 25, 30 minutes there is no bacterialgrowth. Control or no exposure to ozone gas mean is 9 x106 CFU / ml. The time ofexposure to ozone gas is most effective in killing Escherichia coli bacteria ie at 20minutes.Keywords: ozone gas, Escherichia coli, Exposure time.

Abstract

Liquid from the fermentation result of cabbage and mustard vegetable-waste is potentiallybecame  probiotic bacterium source. Vegetables and fruits submersion on low or high degree ofsaline (NaCl) will affect the growth of microorganisms from bacteria class that is, LactobacillusPlantarum. Lactobacillus Plantarum is involved in the formation of lactic acid duringfermentation. Leuconostoc, Lactobacillus, and  Pediococcus convert the sugar in the vegetablesinto lactic acid so that limiting the growth of other organisms. The purpose of this research is toidentify probiotic bacterial protein from cabbage and mustard vegetable-waste using SDSPAGEelectrophoresismethodandprobioticbacterialspeciesusingAPI50CHLV5.1method. Theresult of the research is expected in the form of Lactobacillus bacteria can be used as astarter probiotic that has benefit for health. Result reveals that Lactobacillus isolates 3a and 5aare able to grow at low pH (pH 1.5 and 3) and room temperature. The characterization result ofwhole proteins by SDS-PAGE electrophoresis method against two Lactobacillus isolates (3aand 5a isolates), each obtained 13 bands protein. The 13th molecular weight of 3a isolate proteinband, consecutive, as follows: 124.4; 111.6; 102.3; 93.97; 86.2; 79.0; 66.6; 56.1; 43.3; 39.8;36.4; 33.4; and 29.4 kDa.
