Abstract

The ability to mature and fertilize oocytes of endangered species may allow us to sustain genetic and global biodiversity. Epididymis sperms may be the last chance to ensure preservation of genetic materials after injury or death of a valuable animal. Studies have been conducted to determine wether both epididymis sperms and oocytes can be used to produce viable embryos and offspring. The purpose of this study was to determine how long cats sperms contained in epididymis were remain motile and had intact membranes when preserved at 4 oC, and to determine whether such those preserved sperms are able to fertilize oocytes. Epididymis was preserved immediately in phosphate buffer saline at 4 oC for 1, 3, and 6 days. The observation of sperm quality and viability after preservation was performed by vital staining acrosom and Hoechst-Propidium Iodine. Biological functions of sperms were evaluated by in vitro culture technique for fertilization, micro fertilization and embryonic development rate in CR1aa medium. The results showed that average motility of sperms collected from ductus deferens, cauda and corpus epididymis decreased not significantly (P > 0.05) from 0, 1, 3, and 6 days of preservation times (from 83.0%, 80.2%, 79.0%; 80.9%, 75.0%, 75.5%; 52.0%, 63.2%, 55.0% to 34.6%, 34.6%, 33.3%, respectively). The general results showed that sperms from epididymis preserved for 1, 3, and 6 days can be used for IVF. The rate of embryonal cleavage produced by IVF technique using sperms collected from epididymis preserved for 1-, 3- and 6-days were 33.3, 26.7, and 20.0%, respectively and significantly different (P < 0.05) from that of controll (50.0%). In conclusion, sperms contained in epididyimis preserved at 4 oC in PBS (Phospate Buffer Saline) for 1-6 days can be used to IVF and in vitro production of cat embryos.

Abstract

Experiments were conducted on the morphology, fertilization and embryo development rate of vitrified ovine oocytes matured in vitro. Three vitrification solutions were used for vitrification. PBS supplemented with 1% BSA, 30% ethylene glycol was added by one of three different sucrose concentrations, 1.00 M (VS1), 0.50 M (VS2), and 0.25 M (VS3). The results showed that the percentages of normal vitrified oocytes after warming were 78 and 63% in VS1 and VS2, respectively, which was significantly higher as compared for VS3. The fertilization rates were 59 and 66% in VS1 and VS2, respectively, which were also significantly higher as compared with VS3 (35%). Zygote viability after 18 h was 57; 43; and 40%, for VS1,VS2, and VS3, respectively, which was not significantly different. The incidence of polyspermic penetration increased with increasing sucrose concentration, i.e 23, 11, and 9% in VS1, VS2, and VS3, respectively, as compared with unvitrified oocytes (4%). The cleavage rate of vitrified oocytes in VS1 was 13.2% which was significantly lower (p

Abstract

Cancer disease are not detected only at adult but also at young age. One therapy for cancer diseases is chemotherapy and radiation, that give a side effect of infertility in the gonad, therefore, it is necessary to preserve the gonad. Sperm collection from adult is easy but not from the young patients.Keyword: transpalantation, testis, mencit muda, spermatogenesis

Abstract

Research has been conducted to study the effect of ovaries preservation at 5°C on the oocytes development capacity i.e the capacity of oocytes to undergo in vitro maturation (IVF), in vitro fertilization (IVF) and in vitro embryo development. Goat ovaries were abtained from slaughterhouse in saline solution containing 0.1% Bovine Serum Albumine (BSA) and antibiotic and kept at 5°C for 3 and 12 hours. As control, untreated ovaries were kept for 3 hours at 30-35°C, the temperature usually used for ovaries transportation. The oocytes were aspirated from follicles with 2-5 mm in diameter using 20G needle connected to a 5 ml syringe containing modified phosphate buffered saline (mPBS). The aspirated oocytes were incubated in 100 µl  micro drops of tissue culture medium -199 (TCM-199) supplemented with 10% newborn calf serum (NBCS), 0.01 mg/ml follicle stimulating hormore (FSH) and 50  µg/ml   gentamycine sulphate for 24 hours at 38.5 °C in 5% CO2 incubator. In vitro fertilization (IVF) was done in CO2 incubator at 38.5 °C for 18 hours using fresh semen. Inseminated by their nuclear status after aceto-orcein staining. The results showed that the avarage number of morphological normal oocytes collected from 5 °C  preserved  ovaries were significantly lower than from the untreated control ovaries. After 24 h incubation the percentage of matured oocytes from the 3 ang 12 h preserved ovaries were 85.3± 2.8% and 75.5±  2.2%, respectively (P

Abstract

Telah dilakukan penelitian pada kancil (Tmgulus javanicus) di Kebun Binatang Ragunan - Jakarta dan Kebun Binatang Wonocolo - Surabaya untuk mendapatkan jenis makanan yang disukai, dan aktifitas makan, minum dan ruminasi dari kancil yang dikandangkan.Pada penelitian ini, disediakan 10 jenis makanan dan empat jenis diantaranya yaitu pisang, kacang panjang, kangkung dan pepaya lebih disukai. Aktifitas makan dilakukan pada siang dan malam hari, dan pada saat istirahat kancil melakukan aktifitas ruminasi. Perilaku makan dan ruminasi ini berbeda dengan perilakunya di habitas asalnya. Sedangkan aktifitas minum, jarang dilakukan, hal ini mungkin disebabkan oleh tingginya kadar air di dalam makanan yang disediakan. Aktifitas makan dari kancil yang dikandangkan telah berubah menjadi diurnal dan nokturnal.

Abstract

The influence of various types of sera i.e. Fetal Calf Serum (FCS), Bovine Post Estrous Serum (SPES) as heterolog sera; and Ewes Fetal Serum (EFS) and Ewes Serum (ES) as homologue sera on in vitro maturation and fertilization of sheep oocytes was investigated using Tissue Culture Medium 199TM (TCM 199. Gibco). Sovine sera were collected from cow at seven days post-estrus, while ewes sera were collected during estrous (ES-HO) and six days post estrous (ES-H6). The result shows that the maturation rate of oocytes cultured in medium supplemented with EFS, ES-HO and ES-H6 at  concentrations of 32.9%, 68.7%, and 67.6% respectively is better than those supplemented with FCS and SPES at concentrations of 22.2% and 28.9%, respectively. In vitro fertilization rate were significantly higher in medium supplemented with ES-HO and ES-H6 at concentration of 65.4% and 65.8% (P < 0.05) than that supplemented with SPES at concentration of 31.7%. In conclusion, ewes sera could be used in culture medium for promoting both in vitro maturation and fertilization rate of sheep oocytes.

Abstract

Seagrasses, one of the important ecosystems in Indonesian coastal waters, have declined mostly due to a variety of multi-sector (i.e. ecology, socio-economy, technology and institution) anthropogenic disturbances. The decline and loss of seagrass meadows will have an effect not only on biodiversity and fisheries productivity within the ecosystems but also on the adjacent ecosystems (coral reef and mangrove forest), and even the effect will spread out far to the outside of the areas where seagrass grow.  Seagrass ecosystems management in Indonesia is urgently required as part of fisheries management. However, this concept has not been understood by most of Indonesian people, including some government officials. Consequently, the seagrass ecosystems are still marginalized in the coastal resource management practices in Indonesia. In order to sustain fisheries productivity, knowledge of impact scales of each seagrass-related multi-sector human activities are very important as one of basic requirements in designing an effective seagrass management.

Abstract

Penelitian ini bertujuan membandingkan pengaruh nutrasetikal galohgor dalam bentuk serbuk (GS) dan ekstrak (GE) terhadap proliferasi, morfologi, dan ekspresi gen Aldh1a2 pada sel epitel usus (CMT-93). Galohgor serbuk (GS) dibuat dengan menghancurkan semua bahan dandikeringkan menggunakan drum-dryer sedangkan GE dibuat dengan mengeringkan semua bahan dengan oven, digiling, dan dimaserasi dengan etanol selama 3x24 jam. Perlakuan didasarkan pada konsentrasi akhir β-karoten yang berasal dari GS dan GE masing-masing sebesar 0,5; 1,5; dan 5,0 µM dalam larutan medium Dulbecco's Modified Eagle's medium (DMEM) yang dilengkapi serum (10%). Analisis proliferasimenggunakan asai 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), dan ekspresi gen dianalisis dengan reverse transcriptasepolymerase chain reaction (RT-PCR). Hasil penelitian meunjukkan bahwa GE pada konsentrasi tinggi (5,0 μM) secara signifikan (P0,05) dapatmenekan proliferasi dan memengaruhi morfologi sel CMT-93. Beta-karoten dalam GE dan GS memengaruhi ekspresi gen Aldh1a2 pada sel epitel usus CMT-93
