Judul: Erythrocyte Profiles of 31 Days Old Male Piglet (Sus scrofa domestica) in Animal Laboratory and Research Unit Bogor Agricultural University
Abstrak: Babi domestik (Sus scrofa domestica) merupakan hewan yang sering dijadikan sebagai hewan uji karena kemiripannya dengan manusia baik dari sisi anatomi maupun fisiologi. Informasi terkait profil darah standar pada piglet domestik di Indonesia masih sangat terbatas. Penelitian ini bertujuan untuk memperoleh profil eritrosit pada piglet domestik di UPHL IPB. Hasil penelitian ini diharapkan dapat menjadi rujukan profil eritrosit pada piglet domestik di Indonesia. Sebanyak enam ekor piglet jantan yang terdapat di Unit Pengelola Hewan Laboratorium, Institut Pertanian Bogor diambil sampel darahnya melalui vena auricularis, kemudian dimasukkan ke dalam tabung vakum yang berisi antikoagulan (K3EDTA) untuk selanjutnya diuji menggunakan hematology analyzer. Data dianalisis secara deskriptif dan ditampilkan dalam bentuk rata-rata ± standar deviasi (minimum–maksimum). Hasil pemeriksaan profil eritrosit piglet domestik di UPHL IPB menunjukkan rata-rata jumlah eritrosit adalah 6,42 ± 1,03 juta/µL dengan rata-rata kadar hemoglobin 8,30 ± 1,51 g/dl, rata-rata nilai hematokrit sebesar 29,80 ± 5,10%, MCV 46,47 ± 1,62 fL, MCH 12,83 ± 0,65 pg, MCHC 27,75 ± 0,71 g/dL, dan RDW sebesar 28,87 ± 3,86%., Domestic pig (Sus scrofa domestica) is well known as animal that used frequently as a research animal due to their similarity to human both in terms of anatomy and physiology. Information regarding standard value of domestic piglet’s hematology in Indonesia are still limited. The aim of this study was to obtain erythrocyte profiles of domestic piglets in Animal Laboratory and Research Unit, Bogor Agricultural University. The results of this study are expected to be used as an erythrocyte profiles reference of domestic piglets in Indonesia. Blood samples were collected from six male piglets in Animal Laboratory and Research Unit, Bogor Agricultural University through auricular vein, then the samples were put into a vaccuum tube containing anticoagulant (K3EDTA) for further test using hematology analyzer. Data were analyzed descriptively in the form of mean ± standard deviation (minimum–maximum). The results of this study showed that the average of erythrocyte counts were 6,42 ± 1,03 millions/µL with 8,30 ± 1,51 g/dl hemoglobin concentration, hematocrite 29,80 ± 5,10%, MCV 46,47 ± 1,62 fL, MCH 12,83 ± 0, 65 pg, MCHC 27,75 ± 0,71 g/dL, and RDW 28,87 ± 3,86%.

Judul: Erythrogram Profile of Pig (Sus scrofa domestica) Before and After the Myocardial Infarction Condition with total occlusion of the circumflex artery
Abstrak: Penelitian ini bertujuan mengetahui gambaran eritrogram babi (Sus scrofa domestica) sebagai hewan model pada keadaan sebelum dan sesaat setelah kondisi infark miokard dengan oklusi total arteri sirkumfleks. Babi dengan jumlah 9 ekor dilakukan aklimatisasi. Hewan dipuasakan minimal 12 jam sebelum dilakukan operasi. Babi dianastesi menggunakan ketamin 10% (dosis 0,5 mg/kg) dan xylazine 2% (1 mg/kg). Operasi pembuatan infark miokard dilakukan oklusi total dengan cara ligasi pada cabang proksimal dari arteri sirkumfleks dengan jahitan non- absorbable polypropylene 5.0 monofilament. Hambatan aliran darah dilakukan dengan rentang waktu 2 - 3 jam. Pengambilan darah dilakukan sebelum dan sesaat setelah terjadinya infark jantung dengan masing - masing pengambilan sebanyak ± 3 ml dilakukan melalui vena jugularis kemudian dimasukkan ke dalam vacutainer yang berisi antikoagulan K3 Ethylenediaminetetraacetic acid (K3EDTA). Sampel darah dilakukan pemeriksaan eritrogram menggunakan hematology analyzer terhadap jumlah eritrosit, kadar hemoglobin, nilai hematokrit, dan indeks eritrosit (MCV, MCH, dan MCHC). Hasil penelitian menunjukkan rata-rata eritrosit, hemoglobin, MCV, MCH, dan MCHC sebelum dan setelah infark miokardium (2 – 3 jam setelah oklusi total arteri sirkumfleks) masih berada pada nilai kisaran normal, sedangkan rata-rata hematokrit berada dibawah kisaran nilai normal. Satu ekor babi ditemukan sebelum dan setelah infark memiliki hasil yang merujuk pada terjadinya anemia mikrositik hipokromik., The objective of this research was to determine the profile of the erythrogram of pigs (Sus scrofa domestica) as animal models in the conditions before and shortly after the myocardial infarction with total occlusion of the circumflex artery. A total of 9 pigs were acclimatized. Pigs were fasted for at least 12 hours before surgery. Pigs were anasthetized using 10% ketamin (0.5 mg/kg dose) and 2% xylazine (1 mg/kg). Myocardial infarction surgery was performed in total occlusion by ligation of the proximal branch of the circumflex artery with a non-absorbable polypropylene 5.0 monofilament suture. Blood flow resistance occurs with a period of 2 - 3 hours. ± 3 ml of blood was drawn through the jugular vein and then put into a vacutainer containing the anticoagulant K3 Ethylenediaminetetraacetic acid (K3EDTA). The blood sample was then examined for erythrogram using a hematology analyzer on the number of erythrocytes, hemoglobin level, hematocrit value, and erythrocyte index (MCV, MCH, and MCHC). The mean values of erythrocyte, hemoglobin, MCV, MCH, and MCHC parameters before and after myocardial infarction (2 – 3 hours after the total occlusion of the circumflex artery) were at normal values. In contrast to the average hematocrit which is below the normal value. One of the pig show results that refer to the occurrence of microcytic hypochromic anemia.

Abstrak: Hash function is used to secure the integrity and authenticity of a massege, so that the message is save. The message which will be secured, will be attached to hash/message digest/digital signature value fro, the message. A secure hash function is the one which has pre-image resistance, 2nd pre-image resistance and collision resistance. Hash function has been classified into hash keyed function (Message Authentication Codes/MAC) and unkeyed (Modification Detection Codes/MDC)
