Bovine respiratory diseases cause serious economic loses and present diagnostic difficulties due to the variety of etiologic agents, predisposing conditions, parasites, viruses, bacteria and mycoplasma, and may be multiple or complicated. Several agents which have been isolated from the abnormal lungs are still the subject of controversy and uncertainty. These include adenoviruses, rhinoviruses, syncytial viruses, herpesviruses, picornaviruses, mycoplasma, chlamydiae and Haemophilus somnus.Previously, we have studied four typical cases of bovine pneumonia obtained from the Michigan State University Veterinary Diagnostic Laboratory to elucidate this complex syndrome by electron microscopy. More recently, additional cases examined reveal electron opaque immune deposits which were demonstrable on the alveolar capillary walls, laminae of alveolar capillaries, subenthothelium and interstitium in four out of 10 cases. In other tissue collected, unlike other previous studies, bacterial organisms have been found in association with acute suppurative bronchopneumonia.

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.

Abstract Petunia plants were raised from seed in 6 inch clay pots for 10 wks reaching a height of 10-12 inches in a research greenhouse infested with whitefly at Michigan State University. Each treatment including a control was replicated 6 times. Each replicate was a single plant. Precounts of 5 leaves taken randomly from each plant were completed on 14 and 21 Jul. All immature whitefly (pupae and larvae) were counted. The treatments were blocked based on these precounts. Applications were applied on 22, 30 Jul and 6 Aug with a R&D CO2 sprayer with a single 8008 nozzle at 50 psi until first runoff. Postcounts were made in the same manner as precounts on 28 Jul, 4, 12 Aug.
