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. Key words: gamet, preservation, in vitro fertilization

Biji pinang memiliki potensi sebagai bahan antifertilitas dan diduga dapat menginduksi apoptosis sel-sel spermatogenik. Penelitian ini membahas tentang perubahan jaringan testikular mencit akibat pemberian ekstrak etanol biji pinang muda. Ekstrak etanol biji pinang muda disiapkan dengan maserasi, penjemuran, perendaman dan evaporasi hingga diperoleh serbuk ekstrak etanol yang kemudian dilarutkan dalam larutan Gum Arab 1% sesuai dosis. Mencit jantan galur Swiss Webster (umur8 minggu, berat 30-35 gram) dibagi dalam 5 kelompok perlakuan: (1) K = Kontrol, (2) KP = Kontrol pelarut (Gum Arab 1%), (3) P1 = Perlakukan 1 (dosis 300 mg/kg berat badan (bb)), (4) P2= Perlakuan 2 (dosis 500 mg/kg bb), dan (5) P3=Perlakuan 3 (dosis 700 mg/kg bb), diberikan secara oral (gavage) selama 17 hari. Mencit ditimbang sebelum perlakuan dan setelah perlakuan. Mencit dibunuh pada hari ke 18 dengan dislokasi leher, testis diisolasi, ditimbang dan difoto untuk mengetahui penambahan berat dan ukuran. Preparat histologi sayatan testis disiapkan dengan pewarnaan HE dan TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) assay untuk mengamati apoptosis. Hasil pengamatan menunjukkan terjadi (1) penurunan berat relatif testis kelompok P3, (2) ukuran testis relatif lebih kecil pada kelompok perlakuan, (3) perbedaan struktur jaringan testis pada kelompok P2 dan P3, al: (a) jumlah tubulus seminiferus lebih sedikit, (b) diameter tubulus seminiferus lebih kecil, (c) jarak antar tubulus seminiferus lebih renggang, (d) penurunan jumlah sel testikular, dan (e) peningkatan jumlah sel yang mengalami apoptosis. Ekstrak etanol biji pinang menyebabkan peningkatan apoptosis dan memiliki potensi sebagai agen alami antifertilitas pria.

Identification of sequence polymorphism on the D-loop region of mtDNA has been done for various purposes, including health and medical treatment. In this research, single nucleotide polymorphisms were identified in the D-loop region of mtDNA of the Sundanese population in western Java. A total of 118 unrelated and healthy Sundanese probands were collected from closed-traditional kampung adat and open communities distributed in 14 cities and regencies in western Java. DNA amplification and direct sequencing of the D-loop region were proceeded using primers L15990 and H409. Multi-alignment was conducted not only intrapopulation but also with D-loop sequence data stored in GenBank for comparison. In this research, we categorized high-frequency SNPs as less effective for identification in population studies because of their presence in other populations outside Indonesia. Meanwhile, lower-frequency SNPs showed typical variants of Sundanese haplotypes. On the other hand, rare or low-frequency SNPs should be re-examined in larger size of samples to have a better understanding of risk factors for many diseases.
