Abstract

Background. Tuberculous infection in brain can cause microglia to secrete inflammatory factors like Tumor Necrosis Factor alpha (TNF-α) and Interleukin 1 beta (IL-1β) which will be shown as body immune respons. Those inflammatory factors eventually can trigger microglia to secrete Matrix Metalloproteinase-2 (MMP-2) which will regenerate necrotic or apoptosis cells because of inflammation process. MMP-2 has been proven to have important role in brain tuberculous infection.Objective. To ascertain MMP-2 expression in mus musculus brain tissue with no infection, infection for 8 weeks, and infection for 16 weeks.Methods. This research used semiquantitative method to compare MMP-2 expression in 3 samples group. Observation of MMP-2 expression in mus musculus brain tissue were made by using immunohistochemistry colouration method which then would be observed in microscope with 400x magnification. Brain cell which express MMP-2 will become brown in cell nucleus, cytoplasm, and wall.Results. The result which had be obtained was overtime reduction of MMP-2 expression.Conclusion. MMP-2 expression didn’t decrease after 8 weeks time of infection.

Abstract

Background. Ischemia on the cells and the lack of supply of glucose, will trigger a Ca2 + influx into the cell and increased expression of glutamate. Result in mitochondrial Ca2 + Influx be "overloaded". Glucose metabolism then switched to the anaerobic process that makes ATP increasingly depleted and there acidosis. This situation makes the neuron cell apoptosis triggered to occur. Apoptosis is programmed cell death. Neuron cell apoptosis is thought to have a strong connection to the tuberculosis infection in the brain.Objective. To determine the number of cells undergoing apoptosis neurons in brain tissue of mice.Methods. This study is a semiquantitative by comparing the number of cells undergoing apoptosis neurons in the three groups of samples. Observations apoptosis of neuronal cells in the brain tissue of mice was conducted using TUNEL staining technique (terminal deoxynucleotidyl transferase dUTP nick end labeling) are seen in a microscope with a magnification of 1000x.Results. The results showed that neuronal cells undergo apoptosis in brain tissue infected with M.tb for 8 and 16 weeks were marked with brown color in the cell nucleus. Neuron cell apoptosis were observed at M.tb-infected brain tissue for 16 weeks.Conclusion. The longer the M.tb infection can affect the increase in the number of neuronal cell apoptosis.

Abstract

Infeksi mikobakteria termasuk diantara infeksi yang paling sulit disembuhkan dari semua jenis infeksi bakteri. Mikobakteria yang patogen utamanya adalah Mycobacterium tuberculosis sebagai penyebab tuberkulosis (TB), yang mengakibatkan lebih banyak kematian daripada agen mikroba tunggal lainnya di seluruh dunia. Penelitian ini menggunakan Mycobacterium sp. yang bermanifestasi klinis tuberkulosis atau mirip tuberkulosis. Salah satu usaha untuk mengobati penyakit infeksi akibat Myco­bacterium sp. yang bermanifestasi klinis penyakit tuberkulosis atau mirip tuberkulosis adalah dengan menggunakan isoniazid. Terapi tunggal dengan isoniazid dan kegagalan penggunaan isoniazid ditambah obat lain yang sesuai telah mengakibatkan prevalensi resistensi isoniazid sebesar 10-20% dalam uji klinis di Karibia dan Asia Tenggara. Penelitian ini bertujuan untuk mengetahui apakah bakteri Mycobac­terium sp. yang berasal dari pasien RSSA Malang sudah resisten terhadap isoniazid. Penelitian bersifat semi kuantitatif untuk mengetahui resistensi Mycobacterium sp. terhadap isoniazid dengan menggunakan metode rasio resistensi. Dasar dari metode ini adalah membandingkan minimal inhibitory concentration (MIC) dari strain Mycobacterium sp. dengan MIC dari isoniazid untuk M. tuberculosis strain H37RV. Hasil penelitian menunjukkan bahwa 40% dari total isolat adalah resisten, 20% adalah intermediate resistant dan 40% adalah sensitif. Disimpulkan bahwa telah terjadi resistensi Mycobacterium sp. terhadap isoniazid.Mycobacteria’s infection is one of the most difficult cured infection from all over kind of bacteria’s infection. The major pathogen mycobacteria is Mycobacterium tuberculosis, agent of tuberculosis (TB) that causes more deaths than other single microbes in the world. This research uses Mycobacterium sp. which clinically manifest as tuberculosis or tuberculosis-like disease. One of efforts to cure this infection is by using isoniazid. Single dose of isoniazid and failed use of isoniazid plus other suitable drug have resulted prevalence of isoniazid-resistant about 10-20% in clinical test in Caribbean and South East Asia. This research is aimed to know whether Mycobacterium sp. from RSSA Malang patients has been resistant toward isoniazid. This research uses a semi quasi experimental research to know the resis­tance of Mycobacterium sp. toward isoniazid by using resistance rasio method.

Abstract

Estrogen has anti-oxidative and anti-inflammatory properties, but its levels decrease in postmenopausal women who can trigger oxidative stress. One of the most damaging effects of ROS is lipid peroxidation, and the end product is Malondialdehyde (MDA). Similarly, aging endothelium has increased oxidative stress and endothelial cell sensitivity to apoptosis. This study aimed to determine the effect of cowpea extract on serum MDA levels, aortic endothelial cell counts, and brain MDA levels in the ovariectomy model. Cowpea extract can be used as an alternative to prevent and overcome the effects that occur during menopause, such as cardiovascular problems, decreased bone mineral density, and dementia. The study used 15-month-old female Rattus norvegicus, divided into six groups (OVX, SHAM, OVX+estradiol, OVX+Vu 1.25; 2.5; and 5 mg/kg BW/day). Serum and brain MDA levels were examined by ELISA method, while the number of aortic endothelial cells were examined on histopathological preparations with Hematoxylin & Eosin (HE) staining. The mean value of serum and brain MDA levels decreased with an increase in the dose given (p-value 0.016). The mean value of aortic endothelial cells between the dose groups did not significantly differ. However, the mean value showed an increasing trend as the dose of cowpea extract was given. The results of this study indicate that the extract of cowpea has the potential as an antioxidant to reduce serum and brain MDA levels, prevent a decrease in the number of aortic endothelial cells. As prevention, cowpea extract can be used as an antioxidant and consumed since premenopause to minimize problems that occur during postmenopause.

Abstract

Infeksi Endometrium merupakan peradangan pada lapisan dalam rahim yang disebabkan karena adanya infeksi yang salah satunya disebabkan oleh Streptococcus agalactiae. Streptococcus agalactiae merupakan bakteri Gram positif yang dapat ditemukan pada saluran genetalia dan gastrointestinal sekitar 30% pada wanita. Akan tetapi bakteri ini mampu beradaptasi sesuai dengan lingkungannya sehingga dapat berubah dari bakteri komensal menjadi pathogen. Penelitian ini merupakan penelitian eksperimental murni yang terdiri dari 25 ekor Rattus norvegicus berjenis kelamin perempuan dan  dibagi menjadi 5 kelompok dimana setiap tikus diberikan perlakuan pada hari ke 0, 7 dan 14. Pengambilan data dilakukan menggunakan software image raster 3 dan pengumpulan data kemudian di analisis menggunakan One Way Anova. Hasil penelitian menunjukkan rerata ketebalan epitel endometrium pada kelompok kontrol positif memiliki rerata terendah yaitu 17,89μm, sedangkan rerata ketebalan epitel endometrium tertinggi terdapat pada kelompok perlakuan ketiga yaitu 32,86 μm. Sedangkan hasil tes One Way Anova menunjukkan p=0,000 (p-value<0,05), yang membuktikan bahwa terdapat perbedaan peningkatan yang bermakna terhadap ketebalan epitel endometrium antara Rattus norvegicus pada masing-masing kelompok perlakuan. Maka dapat disimpulkan bahwa pemberian protein pili Streptococcus agalactiae terbukti meningkatkan ketebalan epitel endometrium Rattus norvegicus
