Judul: Komponen Bioaktif dan Aktivitas Antioksidan Kulit Batang Lindur
Abstrak: Mangrove has a lot of benefits that intersect directly with human life ranging from ecology to benefit as a source of food, shelter and medicine. One of them is often found in Indonesia is lindur (Bruguiera gymnorrhiza). This study aims to identify the content of bioactive compounds and determine antioxidant activity of lindur stem bark extract in various solvents. Antioxidant activitiy assay used Free Radical Scavenging Assay was estimated as IC50 values using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and total penolic content in the extracts was calculated as gallic acid equivalent (GAE). The bioactive compounds that identified was in n-hexane extract showed positive results on steroids; the ethyl acetate extract on steroids, flavonoids, tannins, saponins and phenols hydroquinone; methanolic extract on steroids and flavonoids. Ethyl acetate extract showed the highest values of IC50 and phenolic content (37.23 ppm and 73.24 mgGAE/g). The results indicate mangrove species potential for the utilization as significant source of natural antioxidant

Abstrak: Lindur are mangrove plants that has been widely used as drug, yet informations on potential drug compounds and antioxidants contained in lindur were still limited. This study aimed to determine of bioactive compound and antioxidant activity of lindur leave. The result showed that lindur fresh leaves had a moisture content 54.91%, ash 4.49%, fat 1.87%, protein 4.45%, and crude fiber 8.67%. Lindur dried leaves had moisture content 9.78%, ash 8.19%, fat 3.90%, protein 9.78%, and crude fiber content 18.05%. The methanol extract had the highest yield (15.79%) compared to the ethyl acetate extract (2.85%), and n-hexane (1.53%). Bioactive compound found in lindur lindur leave extract was flavonoid, phenol hidroquinon, tannin, saponin, dan streoid. Methanol extract showed the highest antioxidant activity with IC50 values of 81.11 ppm, while the n-hexane extract showed the lowest activity with IC50 values of 815.67 ppm. Total phenolic extracts of n-hexane 12.41 mg GAE/g extract, ethyl acetate 97.57 mg GAE/g extract, and methanol 30.07 mg GAE/g extract.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
