"Penelitian mengenai studi anatomi daun dan akar pada lima spesies Phalaenopsis telah dilakukan. Penelitian dilakukan untuk mendeskripsikan anatomi daun dan akar untuk melengkapi karakter diagnostik dan melihat dugaan potensi adaptasi terhadap cekaman kekeringan. Spesies yang digunakan adalah P. amabilis, P. cornu-cervi, P. fimbriata, P. bellina dan P. tetraspis, lalu dianalisis struktur kontur kutikula, bentuk sel epidermis, bentuk sel mesofil, bentuk sel tetangga, bentuk sel velamen, bentuk eksodermis, dan bentuk endodermis sebagai data kualitatif. Ketebalan daun, ketebalan kutikula, ketebalan epidermis, ketebalan mesofil, luas jaringan pembuluh primer, luas floem, luas xylem, luas akar, ketebalan velamen, ketebalan korteks, ketebalan eksodermis, ketebalan endodermis, luas jaringan pembuluh primer, luas xilem dan luas floem dianalisis sebagai data kuantitatif. Daun dan akar disayat menggunakan hand-sliding microtome untuk pengamatan sayatan melintang, kemudian diamati di bawah mikroskop cahaya. Daun dikerik untuk mendapatkan pengamatan sayatan paradermal. Hasil pengamatan karakter kualitatif dan kuantitatif kelima spesies Phalaenopsis memiliki karakter pembeda pada persebaran stomata, tipe stomata, kontur kutikula, tipe velamen, dan luas stele. Daun Phalaenopsis memiliki variasi bentuk stomata berdasarkan tipe sel tetangga, yaitu tipe tetrasitik, parasitik dan anisositik. daun P. amabilis memiliki stomata amphistomatatik. Daun P. tetraspis memiliki kontur kutikula adaksial dan abaksial berbentuk ridge. Akar P. cornu-cervi memiliki velamen uniseriatus, dan luas stele P. fimbriata memiliki rerata 0,3 mm2. Hasil penelitian telah dilakukan untuk melengkapi data terhadap karakter anatomi daun dan akar.

The study aimed to determine the anatomical character of Phalaenopsis to complement the diagnostic character and the alleged potential for adaptation has been carried out. The objective was to describe leaf and root anatomy structure and compare those structures between species. P. amabilis, P. cornu-cervi, P. fimbriata, P. bellina and P. tetraspis was used in the research. Leaf and root anatomical differences was analyzed by qualitative and quantitative approach. Qualitative data includes the presence cuticle, epidermal cell, mesophyll shape, velamen shape, exoderm shape, and endoderm shape. Quantitative data includes cuticle thickness, epidermal thickness, mesophyll thickness large area of phloem, large area of xylem, velamen thickness, exoderm thickness, endoderm thickness area of stele, area of phloem, and area of xylem. Leaf and root dissected by handsliding microtome, then observed under light microscope for crosssection observation. Leaf scraped for paradermal observation. Result shows differ character in cuticle, stomatal distribution, stomata type and area of stele. The qualitative and quantitative characters of the five species of Phalaenopsis have distinguishing characteristics in stomata distribution, stomata type, cuticle contour, velamen type, and stele area. Phalaenopsis leaves have a variety of stomata forms based on neighboring cell types, which are tetracytic, parasitic and anisocytic types. P. amabilis leaves have amphistomatatic stomata. P. tetraspis leaves have a ridge-shaped adaxial and abaxial contour. The root of P. cornu-cervi has uniseriatus velamen, and the extent of P. fimbriata stele has an average of 0.3 mm2. The results of the research have been carried out to complete the data on the anatomical character of leaves and roots."

"Anatomi daun sembilan spesies anggota genus Bulbophyllum telah dipelajari menggunakan metode freehand section. Karakter yang diamati pada sayatan paradermal daun ialah karakter stomata dan bentuk sel epidermis. Karakter yang diamati pada sayatan melintang ialah karakter stomata, trikom, hipodermis, mesofil, ikatan pembuluh angkut, idioblas, kristal. Fibre bundles, stegmata, dan silica bodies tidak ditemukan pada sembilan spesies yang diamati. Karakterkarakter anatomi tersebut dapat melengkapi deskripsi sembilan spesies anggota genus Bulbophyllum yang diamati. Karakter dimensi stomata berpotensi untuk menjadi karakter pembeda spesies.

AbstractLeaf anatomy of nine species of Bulbophyllum has been studied with freehand section method. Stomatal size, subsidiary cells, dan epidermis cell shape characters are observed in paradermal section. Trichome, stomatal, hypodermis, mesophyll, idioblast, crystal, vascular bundles characters are observed in transverse section. There is no stegmata, fibre bundles, and silica bodies in nine species. Those characters can be added to description of each species. Stomatal size has potential as distinctive character of species. "

"Diagnosis strok sering ditegakkan berdasarkan pembuktian klinis dengan anamnesis dan pemeriksaan klinis neurologis saja. Akan tetapi gambaran klinis yang ditemukan tidaklah selalu sama, seringkali bervariasi sehingga diagnosa topis tidak selalu tepat. Diteliti hubungan antara gambaran klinis dengan topografi anatomi/ tipe infark pada CT-sken otak pad a penderita strok iskemik. Penelitian ini dilakukan secara prospektif, "cross sectional" dan bersifat deskriptif analitik. Populasi adalah penderita strok iskernik kejadian pertama berusia 40 tahun dan 65 tahun yang dirawat di ruang perawatan klas III RSUPN-CM Jakarta. Sejak bulan April sampai dengan Juli 1996, didapatkan 52 kasus strok iskemik kejadian pertama. Terdiri dari 34 laki-laki (65,3%) dan perempuan 18 (34,7%) dengan rasio laki : perempuan adalah 1,9 : 1 . Strok trombosis ditemukan terbanyak yaitu 93,9% sedangkan strok emboli 6,1 %. Dari 52 penderita yang diteliti, didapatkan basil CT-sken otak adalah 29 (59,2 %) berupa infark tentorial , 20 (40,8%) adalah infark lakunar, hanya satu kasus ditemukan berupa infark watershed dan dua lainnya dengan infark multipel. Pada pemeriksaan CT otak pertama, dua kasus tidak memperlihatkan adanya gambaran infark sehingga dilakukan pemeriksaan CT otak yang kedua yaitu antara hari ke 7 - 10 , didapatkan hasil berupa infark lakunar pada kedua kasus tersebut. Hemihipatesis ringan ditemukan pada 44,8% strok dengan tipe infark tentorial dan 70 % pada strok lakunar. Hemihipatesis berat hanya ditemukan pada strok dengan tipe infark tentorial. Hemihipestesi ditemukan 55,2% pada strok tipe tentorial dan 75 % pada strok tipe lakunar. Afasis hanya ditemukan pada strok tent

The diagnosis of stroke is often made based on clinical evidence with anamnesis and neurological clinical examination alone. However, the clinical picture found is not always the same, it often varies so that the diagnosis of topis is not always correct. The relationship between clinical features and anatomical topography/type of infarction on brain CT scans in ischemic stroke sufferers was studied. This research was conducted prospectively, "cross sectional" and is descriptive analytic in nature. The population was first-time iskernic stroke sufferers aged 40 years and 65 years who were treated in class III treatment rooms at RSUPN-CM Jakarta. From April to July 1996, there were 52 cases of first-occurrence ischemic stroke. Consisting of 34 men (65.3%) and 18 women (34.7%) with a male: female ratio of 1.9: 1. The highest number of thrombotic strokes was found, namely 93.9%, while embolic strokes were 6.1%. Of the 52 patients studied, brain CT scan results showed that 29 (59.2%) were tentorial infarctions, 20 (40.8%) were lacunar infarctions, only one case was found to be a watershed infarction and the other two were multiple infarctions. In the first brain CT examination, two cases did not show any signs of infarction so a second brain CT examination was carried out, namely between days 7 - 10, the results were lacunar infarcts in both cases. Mild hemihypathesis was found in 44.8% of tentorial strokes and 70% of lacunar strokes. Severe hemihypathesis is only found in strokes with tentorial infarction type. Hemihypesthesia was found in 55.2% of tentorial type strokes and 75% of lacunar type strokes. Aphasis is only found in tentorial strokes."
