ZusammenfassungEs werden die Fälle einer disseminierten letalen Toxoplasmose bei einer Farbmaus (Mus musculus) und einem Roten Panda (Ailurus fulgens) vorgestellt. Es handelte sich um eine als Haustier gehaltene Farbmaus und einen Roten Panda aus einem sächsischen zoologischen Garten. Die pathologische Untersuchung ergab bei beiden Tieren eine systemische Toxoplasmeninfektion. Eine hochgradige nekrotisierende Hepatitis stellte in beiden Fällen den histologischen Hauptbefund dar. Parasitenzysten fanden sich massenhaft in der Leber, in mäßiger Zahl im Gehirn und in geringer Zahl in anderen Organen. Mittels PAS-Reaktion waren diese Zysten bei der Farbmaus kaum darstellbar, beim Roten Panda dagegen sehr deutlich. PCR bzw. Immunhistologie bestätigten die Diagnose.

Penelitian ini bertujuan mengetahui jumlah sel Purkinje cerebellum anak mencit umur 21 hari (pascasapih) setelah induksi Ochratoksin A selama periode organogenesis. Tiga puluh ekor mencit bunting dibagi secara acak menjadi 5 kelompok perlakuan dengan masing-masing 6 ulangan. Ochratoksin A dilarutkan dalam Sodium Bicarbonat, diberikan secara oral pada saat kebuntingan hari ke 7 sampai hari ke -14. Dosis perlakuan Ochratoksin A adalah 0,5 ; 1,0; 1,5 mg/kg bb dan sebagai kontrol tidak diberi perlakuan, serta kontrol placebo diberi perlakuan pelarut Sodium Bicarbonat. Induk mencit dipelihara sampai melahirkan. Pada umur ke 21 hari (pascasapih), anak mencit dikorbankan dan diambil bagian otaknya. Otak mencit selanjutnya dipreparasi dengan metode parafin dan pewarnaan menggunakan pewarnaan Haematoksilin Eosin. Data jumlah sel Purkinje dianalisis dengan Anava Satu Arah dan dilanjutkan dengan uji DMRT untuk mengetahui beda nyata antar perlakuan. Hasil penelitian menunjukkan bahwa Ochratoksin A yang diberikan pada mencit bunting selama periode organogenesis menyebabkan terhambatnya pertumbuhan jumlah sel Purkinje mencit perlakuan yang ditandai dengan semakin menurunnya jumlah sel Purkinje dibandingkan dengan kontrol dan kontrol placebo.

Telah dilakukan percobaan untuk menentukan tahapan palatogenesis pada mencit (Mus musculus L.) yang rentan terhadap efek polutan 2,3,7,8-Tetraklorodibenzo-p-dioksin (TCDD). Percobaan dirancang mengikuti Rancangan Acak Lengkap dengan pola faktorial (4X3). Empat puluh delapan ekor mencit bunting dicekok TCDD dengan dosis 0 (kontrol), 5, 10, atau 20 μg/kg bb. Perlakuan diberikan pada hari kebuntingan (Hk) 9−10, 11−12, atau 13−14. Mencit kontrol dicekok pelarut saja (98,5% minyak wijen + 1,5% DMSO). Pada Hk 18 mencit dibius lalu dibunuh dengan teknik cervical dislocation, persentase fetus cleft palate (cp) dihitung, derajat penutupan palatum diberi skor, preparat dengan ketebalan 6 µm dibuat, dan mikrostruktur kraniofasial diamati. Hasil menunjukkan, pemberian TCDD antara hari ke 9 dan 12 menginduksi cacat cp, dengan kecenderungan hasil tertinggi pada pemberian Hk 910. Perlakuan TCDD dosis 10 atau 20 μg/kg bb pada Hk 910 menghasilkan fetus cacat cp >90%. Persentase fetus cp tetap tinggi pada pemberian Hk 1112, khususnya pada kelompok dosis 20 μg/kg bb (87,3%). TCDD dosis terendah (5 μg/kg bb) menginduksi cp dominan bercelah sempit, menunjukkan adanya hambatan pada tahap fusi. Dosis 10 dan 20 μg/kg bb menginduksi cp bercelah sedang atau lebar, mengisyaratkan terjadi hambatan pada tahap inisiasi atau elevasi. Disimpulkan, seluruh tahapan palatogenesis rentan terhadap efek TCDD, namun tahap paling rentan adalah tahap fusi palatum.

Patients withdiabetes mellitus (DM) continues to grow because prosperity and people's lifestyles.Treatment of diabetes often usei njections of insulin and oral antidiabetic drugs. Thetreatment has no side effects. Therefore, it is necessary to find effective drugs using plants thatred betel leaf (Piper crocatum Ruiz & Pav.). Red betel leaf contains flavonoids which are antioxidants. This study aims to determine the effect and dose of extract of red betel leaf (Piper crocatum Ruiz & Pav.) The most effective agains blood glucose in mice(Mus musculusL.) male induced sucrose.This study was an experimental study. The research was conducted in October 2015 in the Division of Laboratory Animal and Zoology Department of Biology, State University of Padang. The subject of research in the form of mice (Mus musculus L.) males totaled 24 tails. The design used was completely randomized design (CRD) with 6 treatments and 4 repetitions. The treatment is given as follows: treatment I: the diabetes control without any treatment given, treatment II: as a negative control (sucrose 3 g/kg bw), treatment III: sucrose+suspension of red betel leaf extract (dosage 0,7 g/kg bw), treatment IV: sucrose+suspension of red betel leaf extract (dosage 1,4 g/kg bw), treatment V: sucrose+suspension of red betel leaf extract (dosage of 2,1 g/kg bw) and treatment VI: sucrose+suspension extracts red betel leaf (dosage 2,8 g/kg bw).The results showed that the extract of red betel leaf (Piper crocatum Ruiz & Pav.) at a dose of 0,8 g/kg bw 1,4 g/kg bw 2,1 g/kg bw and 2,8 g/kg bw can lowers blood glucose in mice. However, the most appropriate dose in lowering blood glucose in mice (Mus musculus L.) at 2,8 g/kg bw in mice.

Synthesis of the 4-chlorobenzoylthiourea compound was carried out by acylating thiourea with 4-chlorobenzoyl chloride. The 4-chlorobenzoylthiourea compound  will increase the lipophilic and the electronic properties other than the lead compounds of benzoylthiourea in order to, by expectation, raise the central nervous system depressant as well. The lipophilic would affect the ability of the compounds in penetrating biological membranes, which is highly dependent on the solubility of the drug within lipid/water. Log P is the most common method used in determining the parameter value. This experiment was to mix two dissolvents (octanol and water) which are immissible. The both levels of the compounds were carefully observed by a spectrophotometer UV-Vis. From the test, the result of log P value of the 4-chlorobenzoylthiourea compound was 2.32, while the theoretical log P value of the compounds, by using the π Hansch-Fujita method is 1.62 and the f Rekker-Mannhold method is 2.225. Consequently, the result of the test shows that there is a significant difference between the progress experiment and both theoretical log P methods. Moreover, in the test of the central nervous system depressant through the potentiation test to thiopental using mice indicates that the 4-chlorobenzoylthiourea compound have potentiation effects to thiopental compared to the lead compounds of benzoylthiourea.

Teratogenic is an abnormal development on embryo and is the cause of congenital defect or birth defect. This study aims to determine the effect of the addition of Dioscorea alata L. ethanol extracts to the embryo development on pregnant mice whose given orally to 24 mice which divided to 4 treatment groups, they are the normal group (NG) with NaCMC 0.5%; 28 mg/KgBB treatment group; 35 mg/KgBB; 42 mg/Kg BB. The addition of Dioscorea alata L ethanol extracts was done on the sixth day until the 15th day of pregnancy. On the 18th day of pregnancy, Laparaktomi was done to the pregnant mice and the embryo was taken out of the uterus. The observation was done to the fetus numbers, weight weighing of the fetus's body, dan length measurement of the fetus's body. Another observation is the observation of the external organ defect of the embryo. The study results that the addition of Dioscorea alata L ethanol extracts with various doses have no significant effect (P>0.5) to the mice external fetus development. On the examination of the fetus, we can conclude that Dioscorea alata L ethanol extracts don’t give any effect that may cause the defect of the fetus’ external organ.
