Judul: Aktivitas Antihiperglikemik dan Antioksidan Buah Bakau Merah (Rhizophora stylosa Griff.)
Abstrak: Red mangrove (R. stylosa) is one of rhizoporaceae which has been widely used as antidiabetic drugs. One of the way how to prevent and treat diabetic is by inhibiting activity of the enzyme α-glucosidase. The purpose of this research was to determine the antihyperglycemic activity of crude extract of the red mangrove (R. stylosa) fruit. The research was performed in several steps there were characterization of mangrove fruit, extraction (maceration), proximate test (AOAC 2005), toxicity test (BSLT), antihyperglycemic test (α-glucosidase inhibition), antioxidant test (DPPH), and phytochemical test (Harborne 1987). The result showed that the methanol extract had the highest yield compared to other extracts equal to 3.45%. The methanol extract possessed the most toxic with LC50 values of 116.96 ppm. Ethyl acetate extract had the highest value of α-glucosidase inhibition (IC50) in the amount of 285.56 ppm, followed by methanol extract of 474.97 ppm, and n-hexane extract of >15000 ppm. The antioxidant test result of ethyl acetate extract showed IC50 value 79.71 ppm. Phytochemical test of ethyl acetate extract showed positive results on phenol hydroquinone, flavonoid, steroid and triterpenoid

Judul: Potensi Antioksidan, Inhibitor Tirosinase, dan Nilai Toksisitas dari Beberapa Spesies Tanaman Mangrove di Indonesia
Abstrak: Indonesia is a country rich in biodiversity. Mangrove is a plant that quite a lot in Indonesia. This research was conducted to determine potency of antioxidant, tyrosine inhibitors, and toxicity from some types of mangrove plants. The result showed that the yield of R. stylosa bark extract was 18.07% and it was the highest yield extract. S. caseolaris fruit extract had the lowest LC50 of toxicity (126.73 μg/mL). S. caseolaris bark extract had antioxidant best value with IC50 of 3.03 μg/mL. This extract also had the best potency of tyrosinase inhibitors with IC50 value of 117.67 mg/mL for monophenols and 364.99 mg/mL for diphenols. Active compounds detected in S. caseolaris extract were tannins, saponin, flavonoid, and phenol hydroquinone. S. caseolaris bark extract was the best extract due to the best ability of antioxidant activity and tyrosinase inhibitory activity.

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.
