Judul: Buprenorphine and Fischer-344 Rats Post-operative Stress Levels: Impact on Serum Corticosterone Levels.
Abstrak: The use of laboratory animals in experiment often requires surgical operations. Post-operative condition often associated with pain and stress. Preemptive analgesia and post operative treatment with buprenorphine can reduce post operative pain and stress and prevent prolonged pain. Therefore, the aim of the present study was to test the hypothesis that pre operative treatment of buprenorphine reduces stress and suppresses the pre-operative serum corticosterone levels in Fischer 344 rats. A total of 14 adult male Fischer 344 (F344/Sca) rats permanently catheterized in artery carotis communis were used. During 94 hour post-operatively the blood sample was collected at specific time point using Accusampler®, an automated blood sampling. Corticosterone levels were quantified with ELISA method using sheep polyclonal antibody to corticosterone. Buprenorphine is effective as pre-emptive analgesia in F344 strain. However the dose is higher than what has been reported in Sprague Dawley strain. Buprenorphine 1.0 mg/kg significantly suppressed serum corticosterone levels immediately after rats regain consciousness. Rats in buprenorphine 1.0 mg/kg group were protected from post operative body weight loss and reduced water intake compare to control, nutella, and buprenorphine 0.4 mg/kg group. Quantification of fecal corticosteroid metabolites failed to detect stress in present study.

Judul: Efektivitas Infusa Buah Adas (Foeniculum vulgare Mill.) terhadap Kadar Progesteron Darah Tikus Putih Betina (Rattus norvegicus) Ovariektomi.
Abstrak: Fennel fruit are plants that contains natural phytoestrogen and have a similar effect as natural estrogen. This study was aimed to describe effectiveness of fennel fruit Infussion (Foeniculum vulgare Mill.) on progesteron level of ovariectomy rat (Rattus norvegicus). This research used 25 female rats that were divided into 5 groups. KN is negative control given distilled water 1 ml. KP is positive control given etinil estradiol 0.045 mg/ 100 g body weight. Treatment D1, D2, D3 given infussion of fennel with three different doses of 73 mg, 146 mg, and 292 mg respectively for 100 g BB. Administration of distilled water, etinil estradiol, and infussion of fennel fruit were done for 15 days with the oral route and the last day with vaginal swab. The progesteron level of serum was analysed by using radioimmunoassay (RIA). The result of this research showed that giving infusion of fennel fruit (Foeniculum vulgare Mill.) with highest dosis could trigger showing estrus phase again and have not effect for progesteron level.

Judul: Identifikasi Gelombang Kelvin di Lapisan Tropouse Indonesia Bagian Barat dengan Menggunakan Data Sounding NOAA
Abstrak: Dinamika pada atmosfer menengah didominasi oleh QBO dimima QBO mempunyai pengaruh terhadap sistem sirkulasi secara global yang berkailan dengan berbagai masalah lingkungan. QBO dipercaya dibangkitkan dari hasil interaksi gelombang ekuatorial dengan aliran dasar. Salah satu gelombang ekuatorial yang berskala planeter adalah gelombang Kelvin. Gelombang Kelvin yang sebelumnya teramati pada lapisan stratosfer bawah berada di wilayah India dan Pasifik barat. Posisi Indonesia yang berada diantara dua wilayah tersebut memungkinkan terjadinya gelombang Kelvin di wilayah Indonesia. Namun, karakter yang teramati belum tentu sama. Kondisi aliran dasar dianalisis dengan menggunakan Time-Height Section pada semua val label sedangkan untuk mengidentifikasi gelombang digunakan analisis spektrum dan spektrum silang. Dinamika tropis yang teramati adalah monsun, sirkulasi Hadley, sirkulasi Walker dan pergeseran ITCZ yang mengikuti musimnya. Pada JJAS, ITCZ bergcser ke utara sedangkan pada DJFM ITCZ bergeser ke selatan. Pada troposfer atas, angin zonal yang dominan adalah angin timuran dimana kondisi ini metnenuhi syarat untuk terjadinya gelombang Kelvin.
