Abstract

Aceh swamp buffaloes (Bubalus bubalis) are decreasing their population and genetic quality. This study was conducted to determine the influence of lactose and glycerol cryoprotectants on spermatozoa of Aceh swamp buffaloes after thawing. This study used completelya factorial randomized design with nine treatments, and five replications. Fresh semen of the Aceh swamp buffalo were diluted by using a combination extender lactose cryoprotectants 0 mM (L0), 60 mM (L60), 120 mM (L120) and glycerol 3% (G3), 5% (G5), 7% (G7) with the equilibration of 4 hours. The results showed that the combination of cryoprotectants L120G7 influenced significantly (P 0.05) on the quality of spermatozoa of the Aceh swamp buffalo (B. bubalis) after  thawing. The percentage of sperm motility L120G7 (42.60 ± 1.14); viability L120G7 (55.00 ± 0.71);  acrosome integrity L120G7 (52.00 ± 0.71); and plasma membrane integrity L120G7 (53.20 ± 1.48).  The combination of lactose cryoprotectants 120 mM (L120) and glycerol 7% (G7) was the best combination to maintain the quality of spermatozoa of swamp buffalo. This finding could be used to define a policy for the spermatozoa storage of Aceh swamp buffalo to artificial insemination (AI).

Abstract

Abstract. Flamboyant [Delonix regia (Boj. ex Hook) Raf.] leaf contains flavonoid compounds that are expected to have immunostimulatory effect. This research was done to determine the effect of flamboyant leaf extract on immune response by accessing the activity of immune cells and capability test the extract as immunostimulant in mice. Leaf extraction was done by maceration using methanol in the Laboratory of Biology of Chemistry Department, Faculty of Mathematics and Natural Sciences of Syiah Kuala University whereas animal treatment and testing were carried out Micro-technique Laboratory of Biology Department of the same faculty. This research used 20 male mice strain Swiss-Webster aged 7-8 weeks were randomly assigned to 4 treatment groups with five replications each. Group 1 (P0) was untreated control; group 1-3 were mice administration flamboyant leaf extract 250 mg/kg BW (P1), 500 mg/kg BW (P2), and 750 mg/kg BW (P3) per oral. The treatments were given for 14 days after one week of adaptation period. Blood samples were collected before and after extract treatment and used for leukocyte count analysis. Phagocytosis activity was accessed by carbon clearance assay on day 15. At the end of the study, all mice were sacrificed for spleen weight analysis. Data obtained was analyzed by Analysis of Variance followed by Tukey test (Leukocyte count and spleen weight) or regression analysis (carbon clearance). The results showed a flamboyant leaf extract administration resulted in increased leukocyte counts that were significantly different (p0.05) between treatment groups.  Phagocytosis test indicated the extract had moderate to strong immunostimulatory effect whereas spleen weight analysis did not show any difference among treatment groups. In conclusion, flamboyant leaf methanol extract was able to increase immune cells and had potential immunostimulatory activity in mice.Keywords: Delonix regia, immunostimulant, leukocytes, lymphocyte proliferation.

Abstract

Kanker serviks merupakan penyebab utama kematian perempuan di Indonesia dan dunia, dengan infeksi Human Papillomavirus (HPV) sebagai penyebab utama. Data Kementerian Kesehatan Indonesia menunjukkan bahwa jumlah kasus kanker serviks meningkat dari 18.1 juta kasus global pada 2018 ke 36.633 kasus di Indonesia pada 2023, dengan angka kematian mencapai sekitar 21.000 per tahun secara nasional. Vaksin HPV terbukti efektif dalam mencegah infeksi HPV onkogenik dan menurunkan angka kejadian kanker serviks. Namun, implementasi di berbagai provinsi Indonesia menunjukkan cakupan vaksinasi dan deteksi dini yang belum merata, serta angka kematian yang masih tinggi. Penelitian ini bertujuan meninjau imunogenisitas vaksin HPV, efektivitasnya dalam pencegahan infeksi HPV, serta kebijakan dan hambatan dalam pelaksanaan program vaksinasi di Indonesia. Metode yang digunakan adalah literature review dari jurnal nasional terakreditasi dan data terbaru terkait prevalensi dan program vaksinasi. Artikel yang dikaji berdasarkan topik utama yang relevan dan memiliki data primer dengan tahun publikasi antara 2014-2024. Hasil penelitian menunjukkan bahwa meskipun vaksin HPV tersedia dan digunakan di berbagai daerah di Indonesia, masih terdapat hambatan utama yang meliputi rendahnya pengetahuan masyarakat, kekhawatiran terhadap efek samping, serta kendala biaya dan logistik. Data dari provinsi menunjukkan tingkat deteksi dini berkisar 10-45%, cakupan vaksinasi 20-60%, dan angka kematian bervariasi dari 100 hingga 1.300 kasus di beberapa provinsi, sedangkan secara nasional mencapai sekitar 21.000 kasus per tahun. Kebijakan pemerintah telah mendukung distribusi vaksin, namun peningkatan edukasi masyarakat diperlukan untuk mencapai cakupan vaksin yang lebih luas dan menurunkan angka kematian akibat kanker serviks.

Abstract

This study aims to determine the effect of administering Jamblang Stem Bark Ethanol Extract (Syzygium cumini L.) (JSBEE) on the activity and phagocytosis capacity of macrophages in mice (Mus musculus) infected with Staphylococcus aureus bacteria. The research method used a completely randomized design (CRD) with five treatments and five repetitions, conducted in-vitro and in vivo test. The treatments for in vitro involved administering distilled water (T0), Stimuno (T1), and JSBEE at concentrations of 10 ppm (T2), 100 ppm (T3), and 1000 ppm (T4). Subsequently, in vivo treatment was conducted using distilled water (T0), stimuno (T1), JSBEE at 10 mg/kg (T2), 100 mg/kg (T3), and 1000 mg/kg (T4). Initially, mice underwent in vivo administration of JSBEE, administered orally via catheter tip, with a dosage of 1 mL per 10 g of body weight. JSBEE was administered orally for 10 days, followed by infection with S. aureus on the 11th day. The in vitro tests were conducted by isolating macrophage cells from the intraperitoneal fluid, to which S. aureus and JSBEE were added. Intraperitoneal fluid collected from the mice was used to prepare smears using the thin blood smear method and Giemsa staining. Macrophage phagocytosis activity was observed and assessed based on the percentage activity formula, and the phagocytic capacity of macrophages was measured by the number of S. aureus cells phagocytosed. The results indicated that JSBEE significantly affected (P0.05) both the activity and phagocytic capacity of macrophages in vivo and in-vitro. The best concentration of JSBEE for increasing both the activity value and phagocytic capacity of macrophages was 100 ppm (T3).

Abstract

This study aimed to analyze MSP-1 gene in mice erythrocyte infected with Plasmodium berghei using polymerase chain reaction (PCR). The result showed the existence of 462 bp DNA band which was assumed to encode MSP-1 protein with molecular weight of 19 kDa that can only be found in erythrocyte infected with Plasmodium berghei. BLASTn analysis showed that PbMSP-1 obtained in this study have 100% similar identity with mRNA of PbMSP-1 partial sequence (462 bp), 93% similarity with PbMSP-1 complete sequence (5750 bp and 5376 bp), and 87% similarity with PbMSP-1 incomplete sequence (333 bp).
