Judul: Faktor Pencetus Kejadian Alergi Pernapasan pada Pasien Dewasa di RSUPN Dr. Cipto Mangunkusumo
Abstrak: Alergi pada manusia merupakan bentuk reaksi hipersensitivitas yang terjadi karena tubuh seseorang memproduksi antibodi IgE secara berlebih sebagai tanggapan terhadap adanya alergen. Alergi dapat terjadi di saluran pernapasan berupa asma dan rinitis. Faktor genetik dan lingkungan dapat menjadi pencetus terhadap kejadian alergi pernapasan. Tujuan dari penelitian ini adalah menganalisafaktor pencetus serangan asma dan atau rinitis pada pasien alergi pernapasan di Poliklinik Alergi-Imunologi, Departemen Ilmu Penyakit Dalam, Fakultas Kedokteran Universitas Indonesia, Rumah Sakit Umum Pusat Nasional Dr. Cipto Mangunkusumo, Jakarta.Uji tusuk kulit menggunakan alergen-alergen serbuk sari rumput, kucing, anjing, kecoa, dan tungau debu telah dilakukan terhadap 90 pasien alergi pernapasan. Pasien diwawancara mengenai riwayat alergi pernapasan dari orang tua, dan faktor lingkungan pencetus alergi pernapasan seperti hewan peliharaan, keberadaan asap rokok, dan keadaan emosi. Penderita alergi pernapasan kebanyakan perempuan dan sebagian besar pasien alergi pernapasan dapat dideteksidengan uji tusuk kulit menggunakan alergen tungau debu, akan tetapi, setiap penderita alergi pernapasan belum tentu sama reaksinya terhadap setiap alergen dari 7 alergen uji tusuk kulit. Lebih dari 50% pasien alergi pernapasan memiliki riwayat alergi pernapasan dari orang tua. Keadaan emosi dan keberadaan asap rokok di dalam rumah bagi sebagian besarpasien alergi pernapasan dapat menjadi pencetus timbulnya gejala alergi pernapasan.

Judul: Alergenisitas polen di udara bebas Pasar Minggu Jakarta Selatan pada tikus wistar (Rattus norvegicus).
Abstrak: Allergy cases were frequently reported at kecamatan Pasar Minggu South Jakarta. Pollen is one of the respiratory-system allergen substance which has never been explored in Indonesia. This research was conducted to know the allergenicity of airborne pollen at Pasar Minggu South Jakarta. The protein of airborne pollen at that area was identified and characterized. The detection of allergenicity was made to rat (Wistar strain) by in vivo experiment. There were four kind of airborne pollen found in Pasar Minggu, South Jakarta, which were: maize, dwarf coconut, pine, and oil palm pollen. Their protein concentration were, respectively, 65; 88; 14; and 66 mg/g of pollen. SDS-PAGE results showed that maize, dwarf coconut, pine, and oil palm pollen had several proteins with molecular weight ranging from 17 – 70 kDa; 17 – 68 kDa; 16 - 68 kDa; and 15 – 68 kDa, respectively. Skin inflamation was detected after injection of those protein extract to mouse’s subcutaneous. Respiratory challenge caused an increase in relative weight of respiratory tract. This challenge though, cause a decrease in body weight and an increase in size for mucose membrane cells, a secretion of mucose, and an eruption of inflammation cells. All pollen were allergenic to wistar rat, thus can be utilized as an extract allergen for allergy detection and immunotherapy substances for human in Indonesia.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
