Judul: Potensi Sambiloto dalam Perbaikan Perubahan Histomorfologi Organ Urogenetal pada Tikus Diabetes
Abstrak: The aim of this study is to evaluate the histomorphological aspect of kidney, urinary bladder, testis, and epidydimis of diabetic model rats that were treated with Sambiloto extract. There were 24 male Spraque-Dawley rats, which were divided into 2 groups of models. Diabetic model group was been induced by Streptozotocin (40 mg/ kg BW) intra-peritonially, and a healthy group which received Phosphat Buffer Saline (PBS) pH 7.4 intra-peritonially. The both groups were treated with sambioto daily within 4 weeks and in the following week 3 rats of each group were sacrificed. Respectively in the same way of sacrifice method a sampling was done in every following week. A sample of kidney, urinary bladder, testis, and epidydimis was collected and preserved in 10 % Buffer Neutral Formalin (BNF) and it prepared for histological evaluation. Haematoxiline and Eosin staining was applied to the paraffin block tissue sections for microscopic analysis. Consider the presence of clinical symptoms such as poliuri, glucosuria, and proteinuria in diabetic case, therefore the evaluation focused in histomorfology changes that occur in the urogenital organ based on blood glucose value at the time of sacrifice. Diabetic rat models with both of low and high sugar level at the time of sacrifice was observed as a distinct group. The observation in the kidney, vesica urinary, testis and epididymis of non-diabetic group showed that consumption of sambiloto didn’t affected morphology of kidney, vesica urinary, testis and epididymis. The observations of kidney organs from diabetic rat models with high blood sugar level showed the degeneration, in the glomerulus and tubules can be found the sketch of necrosa and then in tubules also can be found protein sediment. The changes in vesica urinary lead to transitional epithelium degenaration. Observation on the testis organ resulted a decrease in the density of spermatogonia and spermatozoa in tubuli seminiferi. In the epididymis leads to a decrease of spermatozoa density. Evaluation of diabetic model which its blood sugar has decreased after the sambiloto consumption for one month showed a histomorfology improvement in some organs evaluated above until close to non-diabetic group. The result indicated that sambiloto has no harm effect on evaluated tissues of healthy model rats. On the diabetic model rat could be known that sambiloto has therapeutics effect in correlation of hypoglycemic and regenerating cells of evaluated tissues after 4 weeks daily treatment.

Abstrak: REZI ZAHRA AZIZA. B04051740. Histomorphological Aspect of Liver, Small Intestine, and Spleen of Diabetic Model Rat that was Treated with Sambiloto Extract. Under direction of ADI WINARTO and EKOWATI HANDHARYANI The purpose of this study is to evaluate the histomorphological aspect of liver, small intestine, and spleen of diabetic model rats that were treated with sambiloto extract. Twenty-four male Spraque-Dawley rats were divided into 2 groups of models. Diabetic model group was induced by Streptozotocin (40 mg/kg BW) intra-peritonially, and a healthy group which recieved Phosphat Buffer Saline (PBS) pH 7.4 intra-peritonially. The both of groups were treated with sambioto daily within 4 weeks. Rat model of diabetes with low sugar levels and high at the time of sacrifice was observed as a distinct group. Observations on the liver, small intestine, and spleen of non-diabetic group showed that the provision does not affect the morphological sambiloto liver, small intestine, and spleen. Observations on liver of rat diabetic model with blood sugar levels are still high indicates a change in the form of congestion and degeneration, in the small intestine seen an increase in the number of Goblet cells and mitotic cells but did not find any picture of damage to the mucosal epithelium. Changes are seen in the spleen leads to degeneration until necrosa, and spleen increased with the emergence of readiness germinal centers. Evaluation of the liver, small intestine, and spleen model of diabetes with a decrease in blood sugar showed an improvement histomorfologis picture to approach the image on the non-diabetic group.

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
