Hepatic chrrhosis is a chronic disease characterized by increasing formation of connective tissue that spread from portal spaces and also characterized by nodule formation. One of condition which becoming participating factor of hepatic chrrhosis is diabetes mellitus. Based on a data which is collected from medical record of hospital. In diabetes mellitus, it is most likely happened a disturbance of triacylglycerol metabolim. The increased accumulation of triacylglycerol in liver will be happened due to the imbalance between a formation of tryacylglycerol and a formation of VLDL. Another factor which can cause an abundant accumulation of tryacylglycerol is disturbance of the apoprotein formation, so that a VLDL formation is also disturbed. If that situation happens for a long time, the fatty liver is formed and finally hepatic chirrhosis can be happened.

Kerang darah (Anadara granosa) mengandung senyawa glikoprotein yang diperkirakan dapat berperan sebagai zat imunomodulator dengan aktivitas tinggi. Penelitian bertujuan mempelajari potensi kerang darah (Anadara granosa) dalam mekanisme sistem imun tikus (Rattus norvegicus) strain Spraque Dawley. Penelitian dilaksanakan di Laboratorium Kimia Jurusan Kimia FMIPA Universitas Negeri Gorontalo dan Laboratorium Primata Bogor IPB selama periode Maret–Oktober 2015. Peranan itu dijelaskan melalui ekspresi imunoglobulin A (IgA) dan skor histologi rasio CD4+/CD8+ sel T mukosa usus secara imunohistokimia. Metode penelitian adalah eksperimental laboratorik dengan menerapkan randomized post test only control group design terhadap 30 ekor tikus yang dipilih secara simple random sampling. Sampel dibagi dalam lima kelompok: (i) kontrol normal; (ii) dan (iii) adalah sampel malnutrisi yang masing-masing mendapat perlakuan ransum nonprotein sebagai kontrol positif [K.kg(+)] dan ransum standar kasein 20% sebagai kontrol negatif [K.kg(−)]; serta (4) dan (5) adalah sampel malnutrisi yang mendapat perlakuan ransum protein kasein 10% yang dikombinasi dengan tepung kerang darah 10% [P.kg1] dan diberi ransum tepung kerang darah 20% [P.kg2]. Perlakuan terhadap subjek selama 45 hari. Kondisi malnutrisi (kadar albumin<2,7 g/dL) diperoleh dengan pemberian ransum nonprotein. Setelah perlakuan, tikus dinekropsi untuk pengambilan jaringan usus. Pemeriksaan IgA dan skor rasio CD4+/CD8+ sel T jaringan mukosa usus (jejunum dan ileum) dengan metode imunohistokimia. Hasil penelitian menunjukkan kerang darah berpotensi meningkatkan kadar IgA, meningkatkan skor histologi CD4+, dan menurunkan skor histologi CD8+ sehingga memengaruhi peningkatan skor rasio CD4+/CD8+ sel T jejunum dan ileum mukosa usus tikus malnutrisi. Simpulan, terdapat peningkatan jumlah ekspresi IgA pada jejunum maupun ileum mukosa usus kelompok yang diberikan suplementasi kerang darah lebih baik dibanding dengan kelompok tanpa diberi suplementasi. IGA EXPRESSION AND CD4+/CD8+ T CELL RATIO OF RAT INTESTINE MUCOSA AFTER ADMINISTRATION OF ANADARA GRANOSAAnadara granosa contains of glycoprotein that has high activity as immunomodulator. The research objective was to study Anadara granosa’s role on immune system mechanism of rats (Rattus norvegicus) Spraque Dawley strain that described by expression of immunoglobulin A (IgA) and histologic score ratio of CD4+/TCD8+ of intestinal mucosa. The study was held in Chemical Laboratory of Chemical Division of FMIPA Universitas Negeri Gorontalo and Laboratory Primata Bogor IPB during March–October 2015. The method was used experimental laboratory with randomized post test only control group design on 30 rats were selected by simple random sampling and divided into five groups: (1) normal controls, (2) and (3) were malnourished subjects to non-protein food as positive control [K.kg(+)], and food standard with casein 20% as negative control [K.kg(−)], (4) and (5) were malnourished subjects thas treated with casein protein diet 10% combined Anadara granosa flour 10% [P.kg1], and given Anadara granosa flour 20% [P.kg2]. The subjects were treated for 45 days. Malnourished condition (albumin<2.7 g/dL), obtained by non-protein diet. Final step, the samples were operated to get intestinal tissues. IgA examination and CD4+/CD8+ rasio of intestine’s mucosal tissues (jejunum and ileum) by immunohistochemically methods. The results showed that Anadara granosa could potentially increased IgA levels and capable to increase histology score of CD4+ and to decrease histology score CD8+. Increasing of CD4+/CD8+ ratio in jejunum and ileum of rats intestinal mucosa with malnourished after be administrated by Anadara granosa flour. In conclusion, IgA expression increased in jejunum and ileum mucosa of supplementation group is better than non-supplementation.

Chemistry learning has so far emphasized macroscopic and symbolic aspects as a result of misconceptions and students' low understanding of chemistry. This study aims to determine the influence of science process skill through guided inquiry model on student learning outcomes on acidic-basicsolution topic. The type of research is experimental research with Posttest-Only Control Design. Sampling was done by using Purposive Sampling technique. The sample of research for the experimental class and control class were 31 students, respectively. Data collection using objective test as an instrument that contains test about acidic acid material. Data analysis technique used to test the research hypothesis is t-test. Based on the statistical results obtained the average value of post-test experimental class is 58.55 while for the control class the average post-test value is 39.68. Result of data analysis for learning result show that in significant level 0,05 obtained tcount> t table (6,22> 1,671), then H0 rejected or accepted H1. Thus it can be concluded that there is the influence of process skills of science through guided inquiry model on student learning outcomes on acidic acid solution materials.The positive effects are also discussed in this study.

This research aims to analyze the contextual teaching and learning (CTL) model on students' creative thinking skills on the reaction rate topic. This quantitative research used true experimental design of pretest-posttest control. The samples used in this study were from 11th grade at SMA Negeri 1 Pinolosian. The experimental class sample was given treatment of the CTL learning model while the control class used conventional learning, respectively, were 31 and 30 students of 93 populations. Based on a questionnaire, students' creative thinking skills were obtained through observation during the learning process. The data analysis of the test instrument was carried out through a validity test using the product-moment correlation technique (significant level = 0.05), Lilliefors normality test, homogeneity of variance test and ttest. The CTL implementation questionnaire and instrument test data were converted into percentages and categorized. The results showed that the application of the CTL model had a positive effect on students' creative thinking abilities, evidenced by the average score of students in the experimental class before and after treatment increased from 14.55 to 74.84. Otherwise, in the control class, the scores were 30.59 to 33.56. The percentage of students' achievement in creative thinking aspects in the experimental class was good (61%-80%) while the control class was less good (21%-40%). The creative thinking abilities of both classes are very different, which is also reflected in the learning outcomes. The value of tcount (2.240) was greater than ttable (2.042) at the significant level = 0.05, and the hypothesis of H0 was rejected, or H1 was accepted. The application of the CTL learning model positively influenced students' creative thinking skills on the reaction rate material. Students' low originality abilities compared to fluency, flexibility, and elaboration abilities were also discussed.
