The Role of Extracellular Matrix in Tissue Regeneration

Extracellular matrix (ECM) is an extensive molecule network composed of three major components: protein, glycosaminoglycan, and glycoconjugate. ECM components, as well as cell adhesion receptors, interact with each other forming a complex network into which cells reside in all tissues and organs. Cell surface receptors transduce signals into cells from ECM, which regulate diverse cellular functions, such as survival, growth, proliferation, migration, differentiation, and some vital role in maintaining cells homeostasis. This chapter emphasizes the complex of ECM structure to provide a better understanding of its dynamic structural and functional characterization and multipotency. In this chapter the implications of ECM in tissue remodeling are mainly discuss on the neuronal regeneration and wound healing mechanism in the presence of human umbilical mesenchymal conditioned medium (HU-MSCM)

Tidak ada perbedaan yang nyata (P0,05) angka fertilitas antara lama maturasi 20, 22 dan 24 jam dan tidak ada perbedaan yang nyata (P0,05)  angka fertilitas antara lama inkubasi fertilisasi 4, 5 dan 6 jam

Morphological Characteristics of the Stomach of the Swamp Buffalo (Bubalus Bubalis)

The ability of swamp buffaloes for adaptation to swampland was suggested to be supported by their digestive system efficiency including absorption one. This research was done to obtain scientific explanation about digestive efficiency of swamp buffalo by investigating swamp buffalo stomach morphologically. Six stomachs were obtained at slaughterhouse from 2.5-3 years old healthy male swamp buffaloes. Every part of the stomach includes nonglanduler stomach (forestomach: rumen, reticulum, and omasum) and glanduler stomach (abomasum) was taken for measuring length, width, and weight organs. Then all of samples from each part of stomach were prepared for morphological observation. The data were analyzed descriptively. Stomach of swamp buffalo had morphological peculiarities, such as: mucosa surface of rumen, reticulum, and omasum has black color, and there is variation of ruminal papillae of swamp buffalo, including branching. Special characteristics of swamp buffalo stomach is estimated as supporting morphological factors for increasing digestive efficiency to survive in swampland

Studi Anatomi Intestinum Krasum pada Kalong Kapauk (Pteropus Vampyrus)

Pteropus vampyrus is one of the animal species that plays an important role in the ecosystem by spreading the seeds of the edible fruits. Feed variations on each animal greatly affect the digestive tract. This study was aimed to determine the anatomical structure of the large intestine. Five adult large flying foxes weighing 500-800 g were used as the sample in this study. Large intestines were embedded in paraffin and stained with H & E method. H & E staining resulted in the presence of intestinal villi on colon and rectum

Studi Anatomi Catecholamine Mesolimbic Pathway pada Kalong Kapauk (Pteropus Vampyrus) Asal Pulau Timor

Catecholamine mesolimbic pathway (CMP) is a dopamine pathways of the brain that derived from cell bodies in the ventral tegmental area (VTA) to the limbic area i.e. nucleus accumbens, amygdala and hippocampus. In normal conditions, CMP plays a role as controls of motor activity, motivation, emotional and cognitive. Bats are flying mammals which can be potential as natural reservoir of rabies. One of the symptoms of animal rabies is impaired in emotional control that related with limbic system. Kalong kapauk (Pteropus vampyrus) is one of the species of bats that distributed in south Sumatra, Java, Borneo, and spread out to the island of Timor, East Nusa Tenggara. The aim of this research is studying the anatomical structures in CMP of kalong kapauk (Pteropus vampyrus) from Timor island. Four kalong kapauk (Pteropus vampyrus) from Soe-Timor island, East Nusa Tenggara was anaesthetized by using ketamine (20 mg/kg bw) and xylazin (2 mg/kg bw). In deep anesthesia condition, animals were perfused by using physiological saline and after the blood were removed well, the physiological saline were changed to 10% buffered formalin as a fixative. The brain were removed from the cranium, dissected midsagital and processed for histology by paraffin method. The brains were cut in 12 μm thickness and then it stained by using cresyl echt violet and immunohistochemistry by tyrosine hydroxilase antibody. The sections were examined for shape and size of neurons in the VTA and their axonal pathways by light microscope and were documented using a digital camera. The results were analyzed descriptively. The results shows that neurons in the VTA are bipolar and multipolar in shape with the size of 10-32 μm (mean 20.31 ± 4.40 μm) and densities are 15.33 ± 5.71 cells/0,116 mm2. The area of nucleus accumbens, amygdala, and cornua ammonis 3 of hippocampal are TH immunoreactive as the axon terminal. The conclusion of this study is there are catecholaminergic neurons in the VTA that made an area limbic pathways i.e. nucleus accumbens, amygdala, and cornua ammonis 3 of hippocampal

STUDI HISTOKIMIA LEKTIN TERHADAP JENIS DAN DISTRIBUSI GLIKOKONJUGAT ABOMASUM KERBAU RAWA (Bubalus bubalis) KALIMANTAN SELATAN

Penelitian ini bertujuan mengkaji efisiensi pencernaan kerbau rawa dengan mengidentifikasi jenis dan distribusi glikokonjugat  pada daerah abomasum kerbau rawa. Enam ekor kerbau rawa jantan 2,5 tahun dan berat badan 300-400 kg digunakan dalam penelitian ini. Sampel diperoleh dari rumah potong hewan (RPH) Kabupaten Banjar, Kalimantan Selatan. Setiap bagian abomasum meliputi kardiak, fundus, dan pilorus diambil untuk pengamatan mikroskopis dengan pewarnaan hematoksilin-eosin (HE) dan alcian blue-periodic acid schiff (AB-PAS). Residu gula glikokonjugat pada abomasum dideteksi dengan pewarnaan histokimia lektin dengan menggunakan wheat germ agglutinin (WGA), ricinus communis agglutinin (RCA), concanavalin agglutinin (Con A), ulex europaeus agglutinin (UEA), dan soybean agglutinin (SBA). Hasil penelitian menunjukkan bahwa daerah kardiak mengandung glikokonjugat D manosa/D glukosa, D galaktosa, dan N asetilglukosamin.  Daerah fundus mengandung D manosa/D glukosa, D galaktosa, L fukosa, N asetilglukosamin, dan N asetilgalaktosamin. Daerah pilorus mengandung glikokonjugat L fukosa dan N asetilglukosamin. Pola reaktivitas daerah kardiak, fundus, dan pilorus kerbau rawa terhadap pewarnaan histokimia lektin memiliki pola yang berbeda dengan ruminansia lain. Jenis glikokonjugat yang dimiliki oleh kerbau rawa tersebut diduga berkaitan dengan fungsi peningkatan kemampuan efisiensi pencernaan kerbau rawa. Setiap bagian abomasum kerbau rawa memiliki jenis glikokonjugat yang spesifik dengan pola distribusi khas sesuai dengan fungsinya

INJEKSI MEDIA KULTUR EMBRIO SUPERNATAN DALAM UTERUS UNTUK MENINGKATKAN ANGKA IMPLANTASI EMBRIO PADA MENCIT

Penelitian ini bertujuan mengetahui pengaruh injeksi media kultur embrio supernatan ke dalam uterus mencit 2 hari sebelum transfer embrio (TE) terhadap angka implantasi, yang diindikasikan oleh adanya embrio dan leukemia inhibitory factor (LIF) pada uterus. Mencit jenis Swiss Albino dibagi menjadi 2 kelompok yakni kelompok perlakuan dan kelompok kontrol, masing-masing terdiri atas 30 mencit. Kelompok perlakuan mendapat injeksi media kultur embrio supernatan (MKES) dalam uterus 2 hari sebelum TE sedangkan kelompok kontrol mendapat injeksi media kultur embrio (MKE) dalam uterus 2 hari sebelum TE. Dua hari setelah TE (h6 kebuntingan), mencit diperfusi dengan menggunakan larutan para formaldehid 4% dan diambil uterusnya. Uterus diproses untuk blok parafin dan dipotong dengan mikrotom setebal 5 µm. Preparat dideparafinisasi dan diproses imunohistokimia dengan kit ABC dan antibodi LIF. Preparat diperiksa di bawah mikroskop untuk melihat implantasi embrio, distribusi LIF, dan jumlah LIF di desidua dan non-desidua. Angka implantasi antara kelompok perlakuan dan kelompok kontrol masing-masing adalah 52,77 dan 40,88% (P0,05). Jumlah LIF desidua pada kelompok perlakuan dan kelompok kontrol masing-masing adalah 12,83 dan 8,83 (P0,05) sedangkan jumlah LIF di non-desidua antara kelompok perlakuan dan kelompok kontrol masing-masing adalah 8,00 dan 4,50. Dapat disimpulkan bahwa injeksi media kultur embrio supernatan 2 hari sebelum TE dapat meningkatkan angka implantasi pada mencit
