Judul: Kajian patomorfologi organ internal anak kuda yang terserang meningo-ensefalomielitis
Abstrak: Studi kasus ini bertujuan untuk mempelajari kasus meningo-ensefalomielitis pada anak kuda berumur 18 hari yang mati setelah menunjukkan gejala sakit selama 2 hari. Pengamatan terutama berhubungan dengan pemeriksaan patomorfologi organ- organ internalnya. Gejala klinis yang terlihat antara lain demam, kejang-kejang, dan kadang hewan membentur-benturkan kepalanya pada benda lain di sekitarnya. Hasil nekropsi didapatkan cairan serebrospinal berwarna keruh dan berlebihan pada foramen atlanto-occipitale, petechie di permukaan otak, dan perdarahan berbentuk ekimosa pada jaringan subkutan di daerah kepala. Pada pemeriksaan cairan serebrospinal melalui preparat ulas, terdapat sejumlah bakteri berbentuk batang dan sel radang terutama neutrofil. Meningo-ensefalomielitis supuratif diindikasikan melalui temuan patologi mikroskopik antara lain oleh adanya eksudat supuratif pada ruang sub-arachnoid pada cerebrum, cerebellum dan medulla spinalis, abses cerebral multifokal, perivascular cuffing, hemorrhagi dan thrombo-emboli. Pada beberapa tempat lesio ditemukan koloni bakteri. Temuan pada organ internal selain sistem syaraf pusat mengacu pada kejadian septisemia bakterial, dengan adanya disseminated intravascular coagulation, hiperleukositosis neutrofil, splenitis dan limfadenitis akut, pyelonefritis, pneumonia thrombotik interstisial akut dengan pleuritis ringan, dan peritonitis fibrinous. Temuan makroskopik menunjukkan adanya kejadian omfaloflebitis sebagai port d'entre untuk meningo-ensefalomielitis dan septisemia pada kasus ini….

Judul: Kajian Patologi Perforasi Esofagus Pada Kuda
Abstrak: Perforasi esofagus pada kuda adalah kejadian penyakit yang fatal dan dapat menyebabkan kematian. Kejadian perforasi dapat menyebabkan penyakit sistemik pada organ tubuh kuda. Tulisan ini merupakan kajian kasus patologi yang bertujuan mempelajari perubahan patologi anatomi (PA) organ tubuh akibat kejadian perforasi esofagus dan mempelajari efek yang terjadi pada kejadian perforasi esofagus. Seekor kuda berjenis Sandel Wood dinekropsi untuk mengetahui kejadian kasus penyebab kematian. Perubahan PA diperlukan untuk menganalisa dan mengetahui kejadian dari kasus penyakit tersebut. Hasil penelitian menunjukkan terjadi perubahan dari keadaan umum luar berupa selulitis, myositis gangrenosa, pyothorax, pleuritis fibrinopurulen adhesif, laringitis hemoragis, trakheitis hemoragis, dan pleuropneumonia. Pada kuda ditemukan pula kardiomiopati, perikarditis fibrinosa, hemoperikardium, hipertrofi kordis ventrikel kiri jantung, endokarditis, ascites, perforasi esofagus, ptechie limpa dan spenitis, adanya pembengkakkan dan eksudat pada otak. Kejadian penyakit secara sistemik disebabkan oleh adanya bakteri yang masuk ke dalam rongga thoraks akibat antiperistaktik dari lambung yang masuk ke dalam rongga thoraks melalui perforasi esofagus. Bakteri menyebar secara sistemik melalui pembuluh darah dan menyebabkan kerusakan pada organ tubuh kuda., Esophageal perforation is a fatal disease that may caused death in horses. Perforation of esophagus causes systemic illness in the horse's organs. This study aims to investigate the pathological alterations in the anatomy brought on by esophageal perforation, as well as the effects that these alterations on the incidence of the condition. To ascertain the frequency of cases that led to the disease, a horse of the Sandel Wood breed underwent necropsy. The incidence of the disease case was evaluated by investigating at anatomy pathological changes. The findings revealed alterations in the general state of the skin, such as cellulitis, gangrenous myositis, pyothorax, fibrinopurulent adhesive pleurisy, hemorrhagic laryngitis, hemorrhagic tracheitis, and pleuropneumonia. Cardiomyopathy, fibrinous pericarditis, hemopericardium, left ventricular cardiac hypertrophy, endocarditis, ascites, esophageal perforation, splenic petechiae hemorrhage and splenitis, swelling (edema) and exudate in brain were also present in the horse. The presence of bacteria that entered to the thoracic cavity is a result of antiperistaltic from the stomach. Ingesta that entered the thoracic cavity through esophageal perforation caused the incidence of systemic disease. The bacteria harmed the horse's organs by dispersing throughout the blood vessels and producing septicaemia with ending by death.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
