"Cuka apel merupakan salah satu suplemen makanan yang diklaim dapat digunakan untuk menurunkan berat badan oleh masyarakat Indonesia. Namun, jumlah bukti ilmiah yang mendukung pendapat tersebut masih sedikit. Oleh karena itu, peneliti mengadakan sebuah penelitian dengan metode eksperimental dan berhipotesis bahwa cuka apel dapat menurunkan berat badan tikus strain Sprague Dawley. Dalam penelitian ini digunakan 24 ekor Sprague Dawley dengan berat 190-250 gram sebagai hewan coba. Tikus-tikus ini dibagi menjadi 3 kelompok, yaitu kelompok kontrol (sebagai kontrol negatif), kelompok dietilpropion (sebagai kontrol positif), dan kelompok cuka apel. Ketiga kelompok perlakuan diberi makanan dan minuman dengan jumlah dan jenis yang sama. Selama dua minggu penelitian, dari hari ke hari berat badan dan tingkah laku tikus diamati. Data berat badan sebelum dan sesudah terapi dianalisis secara statistik. Pada akhir penelitian, peneliti tidak menemukan adanya penurunan berat badan pada ketiga kelompok perlakuan, akan tetapi efek sebaliknya terjadi peningkatan berat badan tikus. Hasil analisis statistik menunjukkan adanya perbedaan bermakna antara kelompok kontrol dan kelompok cuka apel (p = 0.012 ). Namun, antara kelompok dietilpropion dan cuka apel tidak ditemukan perbedaan yang bermakna. Hal ini juga ditemukan antara kelompok dietilpropion dan cuka apel.

Apple cider vinegar is one of food supplements that commonly used to reduce body-weight by Indonesian citizens. But, there is only few scientific proof that supports this opinion. Therefore, researcher held an experimental study and hipotized that apple cider vinegar could reduce the body weight of Sprague Dawley rats. In this study, 24 rats with body weight 190-250 gram are used as experimental animal. These mice were divided into 3 groups, control group (as negative control), diethylpropion group (as positive control group), and apple cider vinegar group. These 3 groups were given the same amount and type of food and drink. For 2 weeks, the body weight and the attitude of mice were observed day by day. The data of mice?s body weight before-and-after treatment were analyzed statistically using SPSS program. In the end of the study, researcher didn?t find any body-weight loss on the 3 groups, but the result of statistical analytic showed that there was significant difference between control group and apple cider vinegar group (p = 0.012). In the other hand, no significant difference found between diethylpropion group and apple cider vinegar group, as well as between dietyhlpropion group and apple cider vinegar group."

"Belum banyak bukti ilmiah yang mendukung efektivitas cuka apel. Namun, penggunaannya sebagai agen penurun berat badan telah semakin meluas. Bahkan, di berbagai iklan penjualan produk, suplemen makanan ditampilkan seolah-olah memiliki manfaat seperti obat. Untuk itu, peneliti mengadakan penelitian eksperimental dan hipotesis yang akan diuji adalah efektivitas cuka apel tak sebaik yang dimiliki obat standar dalam menurunkan berat badan tikus strain Sprague Dawley. Tikus Sprague Dawley dengan berat 190- 250 gram digunakan sebagai sampel dalam penelitian ini. Ada 24 ekor tikus yang terbagi ke dalam 3 kelompok, yaitu kelompok kontrol (sebagai kontrol negatif), kelompok mazindol (sebagai kontrol positif), dan kelompok cuka apel. Ketiganya mendapat jenis makanan dan minuman yang sama. Berat badan dan tingkah laku tikus diamati selama dua minggu. Data berat badan sebelum dan sesudah terapi diambil dan dianalisis menggunakan uji hipotesis One Way Anova. Peneliti mendapati tidak adanya penurunan berat badan pada ketiga kelompok perlakuan. Akan tetapi, berat badan tikus terus mengalami peningkatan dari hari ke hari.

"Minuman berenergi merupakan minuman yang berfungsi meningkatkan energi orang yang meminumnya. Oleh karena itu, minuman ini banyak dikonsumsi oleh masyarakat. Minuman berenergi umumnya mengandung kafein, suatu zat yang berpotensi menurunkan berat badan dan menaikkan aktivitas fisik. Penelitian ini bertujuan untuk memberikan pengetahuan kepada masyarakat mengenai seberapa jauh minuman berenergi dapat mempengaruhi berat badan dan aktivitas fisik. Pengumpulan data berlangsung pada 14 Desember 2011-2 Januari 2012. Eksperimen dilakukan kepada lima belas ekor tikus yang dibagi menjadi tiga kelompok yang masing-masing mendapatkan minuman berenergi merek 'C', kafein, atau plasebo. Setiap tikus diberi minuman berenergi sesuai dosis dan diamati berat badan serta aktivitasnya. Penelitian menunjukkan berat badan tikus yang mengonsumsi 'C', kafein, dan akuades tidak berbeda secara bermakna (p<0,05). Namun aktivitas fisik berbeda secara bermakna (p>0,05). Efek yang tidak bermakna terhadap berat badan mungkin disebabkan zat-zat yang terkandung dalam minuman berenergi, di mana kafein dan ginseng memiliki efek menurunkan berat badan tapi vitamin B, taurin, dan sebagainya justru meningkatkannya. Namun kafein memiliki efek menghambat adenosin sehingga dapat meningkatkan aktivitas fisik secara bermakna.

Energy drink is a kind of drink that functions to enhance the energy of people who drink it. It's commonly consumed by people. Energy drink commonly contains caffeine, a substance with the potential of reducing weight and increasing physical activity. So, in this research, we want to give people some informations about the effect of energy drink in gaining weight and enhancing physical activity. The collection of data started from 14th December, 2011 until 2nd January, 2012. Experiment is applied to fifteen rats from Sprague-Dawley strain which is separated to three groups and each of groups get 'C' energy drink, pure caffeine benzoate, and placebo (water). After that, their weight gain and physical activity were observed. This research shows that the weight between the rats that were given 'C', caffeine, and water don't show any significant correlation (p<0,05) but there is significant correlation in terms of physical activity (p>0,05). The insignificant correlation on weight gain may be caused by the substances inside the energy drink, in which caffeine and ginseng can reduce weight but the opposite can be caused by taurine and vitamin B. But caffeine can also inhibit the adenosine so that physical activity will be increased significantly."

Background: Ti-6Al-4V is an implant material that is often used to biomedis application but the production costs are still expensive, so that heat treatment is needed to reduce production costs with optimal product results. One of the conditions for implant material is that it must be compatible with surrounding tissue.

Objective: To evaluate the effect of Ti-6Al-4V ELI implan material implantation with 850°C heat treatment on the regeneration of rat femoral bone observed through histology.

Method: This study used an experimental study design with two female Sprague Dawley Rattus novergicus rat on each group. There were three observation groups including normal control group, defect control group, and one treatment group that was given a defect and implanted by the implant material (Ti-6Al-4V ELI) with 850° C heat treatment. Rats were sacrificed in the fourth week and performed histological observation using modified Salkeld scoring.

Result: The results obtained from histological scoring of 2 samples of control group and sample-1 of treatment group are 2 which indicate that they reached the formation stage of fibrocartilago tissue. The histological results of sample-2 treatment groups is 3 which indicates the recovery process have reached mineral cartilage mineralization.

Conclusion: Implantation of Ti-6Al-4V ELI implant material with 850°C heat treatment is acceptable within the nearest bone tissue, observed from bone regeneration process which is indicated by the presence of fibrous, fibrocartilages, and mineralized cartilages."

"Latar Belakang: Ti-6Al-4V adalah salah satu bahan implan yang paling umum digunakan. Dalam upaya mengurangi biaya produksi implan titanium, bahan dipanaskan untuk mengoptimalkan produk akhir mereka. Salah satu kondisi yang perlu dipenuhi untuk bahan implan baru adalah biokompatibilitas bahan untuk jaringan di sekitarnya. Tujuan: Untuk memahami efek implantasi material implan Ti-6Al-4V ELI yang dipanaskan pada 10500C pada tulang paha tikus Sprague Dawley melalui studi histologis. Metode: Desain penelitian eksperimental digunakan dalam penelitian ini dengan tikus Sprague Dawley betina yang dibagi menjadi tiga kelompok: kelompok perlakuan; kelompok kontrol normal; dan kelompok kontrol cacat, yang dibuat lubang pada tulang paha. Dua tikus digunakan di masing-masing kelompok. Pada kelompok yang diberi perlakuan, defek tulang paha diimplantasikan dengan material implan Ti-6Al-4V ELI yang dipanaskan 10500C. Tikus dikorbankan setelah empat minggu dan dievaluasi secara histologis menggunakan Salkeld Histological Scoring yang dimodifikasi. Hasil: Skor histologis kelompok sampel 1 yang diobati adalah 3 yang berarti regenerasi tulang yang hampir sempurna, ditunjukkan oleh penampilan tulang rawan mineral. Nilai untuk kelompok perlakuan sampel 2 dan kelompok kontrol cacat sampel 1,2 adalah 2, yang berarti regenerasi tulang hanya mencapai fase pembentukan fibrocartilage. Kesimpulan: Regenerasi tulang dapat diperoleh di sekitar lokasi implantasi 10500C yang dipanaskan Ti-6Al-4V ELI material implan yang ditunjukkan oleh adanya jaringan fibrosa, fibrocartilage, dan tulang rawan termineralisasi.

Background: Ti-6Al-4V is one of the most commonly used implant materials. In an effort to reduce the cost of producing titanium implants, the material is heated to optimize their final product. One of the conditions that need to be met for new implant material is the biocompatibility of the material for the surrounding tissue.

Objective: To understand the effect of implantation of TiI 6Al-4V ELI material that was heated at 10500C on the femur of Sprague Dawley rats through histological studies.

Methods: The experimental research design used in this study with female Sprague Dawley mice was divided into three groups: the treatment group; normal control group; and the deformed control group, which made a hole in the femur. Two mice were used in each group. In the treated group, femur defects were implanted with the implant material 10500C EL-Ti-6Al-4V. Mice were sacrificed after four weeks and evaluated histologically using modified Salkeld Histological Scoring.

Results: The histological score of the sample group 1 treated was 3, which means almost perfect bone regeneration, indicated by the appearance of mineral cartilage. The values ​​for the sample 2 treatment group and the sample defect control group 1,2 are 2, which means bone regeneration only reaches the fibrocartilage formation phase.

Conclusion: Bone regeneration can be obtained around the implantation site of ELI Ti-6Al-4V implant material heated by 10500C which is indicated by the presence of fibrous tissue, fibrocartilage, and mineralized cartilage."

Tujuan penelitian ini adalah mengetahui efektifitas penambahan Ca3 PO4 2 ndash;nano yang dapat diserap oleh tulang dan melihat struktur kristal yang terbentuk pada tulang setelah diberi purifiet diet dengan penambahan Ca3 PO4 2 ndash;nano. Purifiet diet untuk pakan tikus diberi Ca3 PO4 2-nano dengan variasi komposisi 0,5X, 1,0X dan 1,5X dari kebutuhan normal. Kemudian tikus dipanen setiap dua minggu untuk diambil tulang belakangnya. Pengujian yang dilakukan pada tulang belakang tikus dengan menggunakan Atomic Absorption Spectroscopy AAS , serta X-Ray Diffraction XRD . Nilai efektif dari kebutuhan kalsium yang diperlukan tulang berada pada nilai 0,5X. Kandungan Ca mengalami kenaikan sedangkan kandungan Mg cenderung fluktuatif. Struktur kristal yang terbentuk merupakan tipe heksagonal dari hidroksiapatit dengan ukuran butir yang kecil. Parameter kisi kristal hidroksiapatit yang diperoleh adalah a = 9,50 dan nilai c = 6,83.

ABSTRACTOsteoporosis is a metabolic disease in bones identified by the decreasing of bone mass. The treatment of osteoporosis can be done by adding the level of nano sized calcium Ca 3 PO4 2. The Ca 3 PO4 2 is a mineral contained in the bones to build and strengthen the teeth and bones. The purposes of this research were discovering the effectivity of added nano sized Ca 3 PO4 2 that was absorbed by the bones and identifying the crystalline structure formed at the bone after being given purified diet with the addition of nano sized Ca 3 PO4 2. The purified diet as the food for rats was given with varied compositions of 0.5X, 1.0X and 1.5X of nanosized Ca 3 PO4 2 from the normal requirement. The rats were harvested in every two weeks then their spines were investigated. The characterizations applied for the rat rsquo s spine were Atomic Absorption Spectroscopy AAS and X Ray Diffraction XRD . The effectivity value of the varied composition was found in 0.5X. The calcium content was increasing, while the magnesium content tended to be fluctuating. The crystalline structure was identified as hexagonal from hydroxyapatite with very small grain size. The lattice parameters of hidroxyapatite were a 9,50 and c 6,83."
