Population characteristics and threatened of wild Angelica sinensis in Gansu province / 中国中药杂志

The study aims to investigate spatial distribution pattern and age structure of wild Angelica sinensis in Gansu province.Ten plots each with an area of 100 m2 were set and the spatial coordinates of all wild A. sinensis individuals were measured within each plot. Based on plant individual mapping data,we explored the spatial distribution pattern and its differences between different life history stages of wild A. sinensis in Gansu province by using nearest neighbor distance statistics. Correlation analysis were carried out to explore the relationship between spatial aggregation degree and topographic factors. We also distinguished individuals to three life history stages( i.e. seedlings,adults and boltings) and then test the differences among/between them using nonparametric test.(1)We found that the dominant spatial distribution pattern of wild A. sinensis population in Gansu was aggregated distribution. There was no significant correlation between spatial aggregation degree of wild A. sinensis and altitude,slope and aspect. There was no significant difference between the average distance from seedlings to their nearest bolting individuals; the average distance from adult individuals to their nearest seedlings was significantly larger than the average distance from adult individuals to their nearest adult individuals; and the average distance from bolting individuals to their nearest adult individuals was significantly smaller than the average distance from bolting individuals to their nearest bolting individuals.(2)The age structure was showed as a declining population,characterized by less seedlings and bolting individuals,while more adult individuals within population. The population characteristics of wild A. sinensis,characterized by aggregated distribution pattern and senescent type of age structure,are disadvantage to its population development. The factors,such as habitat specialization,human activities and intraspecific competition,which shapes the current population characteristics,may increase the threatened status of wild A. sinensis. We suggest to strengthen the protection of wild A. sinensis.

Retinal ganglion cells in Strigidae raptors: distribution and morphometry / Células ganglionares de la retina en aves rapaces Strigidae: distribución y morfometría

The authors studied the morphometry and the topographical distribution of Retinal Ganglion Cells (RGCs) in four nocturnal raptors of the order of Strigiformes, family of Strigidae: little owl, tawny owl, scops owl, eared owl. In order to recognize specialized retinal vision areas (fovea and visual streak), the number of RGCs/mm2 and the soma size in the four retinal fields (dorsal, ventral, temporal and nasal) by the histological analysis of retinal radial sections were recorded. A temporal fovea was identified in little owl, tawny owl and eared owl while in scops owl this visual area was localized near the fundus oculi. A radial visual streak ventrally directed was pointed out in the retinas of the four raptors with different shape according to its width. The Authors linked the obtained data with the predatory behavior of nocturnal raptors in their habitat.

Se estudió la morfometría y la distribución topográfica de las células ganglionares de la retina (CGR) en cuatro aves rapaces nocturnas del orden de los Strigiformes, familia Strigidae: búho pequeño, mochuelo, autillo, y cárabo. Con el objetivo de definir las áreas de visión retiniana especializadas (fóvea y campo visual), se registró el número de CGRs/mm2 y el tamaño del soma en los cuatro campos retinianos (dorsal, ventral, temporal y nasal), mediante análisis histológico de las secciones radiales de la retina. Se identificó una fóvea temporal en mochuelo, búho leonado y búho pequeño, mientras que en el búho real, esta área visual se localizó cerca del fondo de ojo. Se observó un campo radial visual dirigido ventralmente en las retinas de las cuatro aves rapaces, con diferentes formas según su extensión. Se relacionaron los datos obtenidos con el comportamiento predatorio de aves rapaces nocturnas en su hábitat.

Number and topographical distribution of retinal ganglion cells in diurnal and nocturnal raptors / Número y distribución topográfica de células ganglionares de la retina en rapaces diurnas y nocturnas

Retinal Ganglion Cells (RGCs) in two diurnal raptors, the buzzard (Buteo buteo) and kestrel (Falco tinnunculus), and in two nocturnal raptors, the little owl (Athene noctua) and tawny owl (Strix aluco), were studied in order to highlight their topographical distribution, taking into account the soma size. Cell density (RGCs/mm2) and median soma area from histological radial sections in four retinal fields (dorsal, ventral, temporal and nasal) were recorded in order to identify specialized retinal vision areas. The results showed a different RGCs distribution between diurnal and nocturnal raptors related to the location of the foveas and shape of the horizontal streak, confirming the bibliographic data. In diurnal raptors, a higher cell density was found in the temporal and central retinal fields as revealed by the presence of a temporal and a central fovea which showed a "horizontal streak". In nocturnal raptors the cell density was higher in the peripheral temporal field likely due to a temporal fovea. A peak in cell density observed in the ventral field, especially in the retina of little owls, might be linked to a more "radial visual streak". Comparing the data obtained we highlighted that the morphology and the number of RGCs are closely linked to the habitat and to the type of predation.

Se estudiaron las células ganglionares de la retina (RGC) en dos aves rapaces diurnas, el ratonero (Buteo buteo) y el cernícalo (Falco tinnunculus), y en dos aves rapaces nocturnas, el mochuelo (Athene noctua) y el búho leonado (Strix aluco), buscando resaltar su distribución topográfica, teniendo en cuenta el tamaño del soma. Se registraron la densidad celular (RGCs/mm2) y la media del área del soma de las secciones histológicas radiales en cuatro campos retinianos (dorsal, ventral, temporal y nasal) para identificar áreas de visión retinianas especializadas. Los resultados mostraron una distribución diferente de RGCs entre las rapaces diurnas y nocturnas relacionadas con la ubicación de las fóveas y la forma de la línea horizontal, lo que confirma los datos bibliográficos. En las aves rapaces diurnas, se encontró una densidad celular más alta en los campos de retina temporales y centrales como lo revela la presencia de una fóvea temporal y central que mostraba una "veta horizontal". En aves rapaces nocturnas, la densidad celular fue mayor en el campo temporal periférico probablemente debido a una fóvea temporal. Un aumento en la densidad celular, observado en el campo ventral, especialmente en la retina de los pequeños buhos, podría estar relacionado con una "línea visual radial". Comparando los datos obtenidos, resaltamos que la morfología y el número de RGC están estrechamente relacionados con el hábitat y el tipo de depredación.

Anatomy description of cervical region and hyoid apparatus in living giant anteaters Myrmecophaga tridactyla Linnaeus, 1758 / Descrição anatômica da região cervical e aparato hioide em espécimes vivos de tamanduá-bandeira, Mymercophaga tridactyla Linnaeus, 1758

The giant anteater has specific anatomical adaptations resulting from its ant and termite feeding habits. The unique arrangement of its hyoid apparatus is essential for the ingestion of food. However, its description in the literature is based on fragments and fossils, making it difficult to determine existing anatomical details in live animals. Imaging techniques, which enable the topographical anatomy of animals to be examined noninvasively, provide essential information for the diagnosis and prognosis of diseases. The aim of this study is to describe the bone contours in the hyoid apparatus of the giant anteater by means of radiographic and tomographic images. Giant anteaters of varying ages from the Wild Animal Screening Center (CETAS-GO) were used, seven for X-ray exams and two adults for CT exams. The hyoid elements in all the animals were evaluated using the two imaging techniques, and were visualized in the cervical region of C2 to C6, which comprises three paired bones (stylohyoid, epihyoid, ceratohyoid) and one unpaired bone (basihyoid). The presence of air in the oropharynx enabled the assessment of soft tissue structures in this region, such as the epiglottis and the soft palate. CT axial sections are of limited usefulness for evaluating the hyoid bones, but enable assessments of the basihyoid bone and its characteristic V-shape. Thus, to analyze the hyoid region in anteaters based on radiographic and tomographic images, one must keep in mind that the stylohyoid, epihyoid and ceratohyoid bones are situated ventrally to the C2 to C5 vertebrae and that the basihyoid at the level of C5-C6 demarcates the transition between the nasopharynx and the trachea. The nasopharynx and oropharynx extend from C1 to C5, and the trachea begins at the level of C6.(AU)

O Tamanduá-Bandeira possui adaptações anatômicas específicas, devido aos hábitos alimentares de ingestão de formigas e cupins. O arranjo singular do aparato hioide dos tamanduás é fundamental para a ingestão de alimentos. Sua descrição na literatura é baseada em peças e fósseis, o que dificulta a determinação de detalhes anatômicos existentes em animais vivos. As técnicas de imagem permitem a avaliação da anatomia topográfica dos animais, de maneira não invasiva, e o conhecimento desta é fundamental para o diagnóstico e prognóstico de afecções. O objetivo desse trabalho foi descrever o contorno ósseo do aparato hioide do tamanduá-bandeira, por meio de imagens radiográficas e tomográficas. Foram utilizados tamanduás-bandeiras provenientes do Centro de Triagem de Animais Silvestres (CETAS-GO), sendo sete, de variadas idades, para os exames radiográficos e dois adultos para os tomográficos. Os elementos hioideos foram avaliados em todos os animais por meio de ambas as técnicas de imagem, sendo visibilizados na região cervical, de C2 até C6, composto por três elementos pares (estiloioide, epioide, ceratioide) e um elemento ímpar (basitireoide). A presença de ar na orofaringe permitiu a avaliação das estruturas de tecidos moles desta região, como a epiglote e o palato mole. Os cortes tomográficos axiais têm importância limitada na avaliação dos hioides, mas permitem a avaliação do basitireoide e de seu formato característico (V-bone). Desta forma, para avaliar a região hioidea por meio dos exames radiográficos e tomográficos em tamanduás-bandeira, deve-se considerar que os ossos estiloioide, epioide e ceratioide localizam-se ventral às vértebras C2 até C5 e o basitireoide, em C5-C6, delimita a transição entre a nasofaringe e a traqueia. A orofaringe e a nasofaringe estendem-se de C1 a C5, e a traqueia inicia-se a partir de C6.(AU)

Role of dental restoration materials in oral mucosal lichenoid lesions.

Background: Dental restorative materials containing silver–mercury compounds have been known to induce oral lichenoid lesions. Objectives: To determine the frequency of contact allergy to dental restoration materials in patients with oral lichenoid lesions and to study the effect of removal of the materials on the lesions. Results: Forty‑five patients were recruited in three groups of 15 each: Group A (lesions in close contact with dental materials), Group B (lesions extending 1 cm beyond the area of contact) and Group C (no topographic relationship). Thirty controls were recruited in two groups of 15 individuals each: Group D (oral lichenoid lesions but no dental material) and Group E (dental material but no oral lichenoid lesions). Patch tests were positive in 20 (44.5%) patients. Mercury was the most common allergen to elicit a positive reaction in eight patients, followed by nickel (7), palladium (5), potassium dichromate (3), balsam of Peru, gold sodium thiosulphate 2 and tinuvin (2) and eugenol (1), cobalt chloride (1) and carvone (1). Seven patients elicited positive response to more than one allergen. In 13 of 20 patients who consented to removal of the dental material, complete healing was observed in 6 (30%), marked improvement in 7 (35%) and no improvement in 7 (35%) patients. Relief of symptoms was usually observed 3 months after removal. Limitations: Limited number of study subjects and short follow up after removal/replacement of dental restoration materials are the main limitations of this study. Conclusion: Contact allergy to amalgam is an important etiologic factor in oral lichenoid lesions and removal of restorative material should be offered to patients who have lesions in close proximity to the dental material.

Perfil de severidad lesional del trauma esquelético maxilofacial / Lesion severity profile of the maxillofacial skeletal trauma

Se realizó un estudio descriptivo, transversal y observacional de 335 pacientes con lesiones esqueléticas maxilofaciales por diferentes causas, atendidos en el Servicio de Cirugía Maxilofacial del Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora Torres" de Santiago de Cuba, desde enero de 2009 hasta diciembre de 2010, con vistas a caracterizarles según los calificadores anatómicos de severidad del trauma, en relación con el mecanismo lesional y el diagnóstico topográfico de estas. En la serie predominaron los pacientes con 3 o más lesiones esqueléticas (37,9 %), puras o combinadas con lesiones de tejido blando del componente bucofacial, así como las moderadas (60,0 %). En los polilesionados prevalecieron las lesiones severas sin peligro para la vida 16-24 puntos) y las severas con peligro para la vida (25-40 puntos). Por otra parte, el tercio medio facial resultó ser la región anatómica donde se localizaron con mayor frecuencia las lesiones severas sin peligro para la vida y con este; mientras que las lesiones individuales moderadas y leves primaron en esta misma región anatómica.

A descriptive, cross sectional and observational study of 335 patients with maxillofacial skeletal lesions due to different causes, assisted in the Maxillofacial Surgery Service from "Saturnino Lora Torres" Clinical Surgical Teaching Provincial Hospital in Santiago from Cuba was carried out from January, 2009 to December, 2010, with the aim of characterizing them according to the anatomical qualifiers of trauma severity, in relation to the injury mechanism and the topographical diagnosis of them. In the series the patients with 3 or more skeletal injuries (37.9%), pure or combined with the soft tissue of the orofacial component, as well as moderate injuries (60.0%) prevailed. In the polyinjured patients, severe lesions prevailed without danger for life (16-24 points) and the severe ones with danger for the life (25-40 points). On the other hand, the middle facial third turned out to be the anatomical region where the severe lesions were more frequently located with and without danger for life; while the moderate and light individual lesions prevailed in this same anatomical region.

Comparison of two topographical airway length measurements in adults / 대한마취과학회지

BACKGROUND: A correct estimate of the tracheal tube insertion depth can prevent complications, including endobronchial intubation and vocal cord trauma. We evaluated a new topographical method for endotracheal tube positioning relative to the carina, using a well-known prior topographical method for comparison. METHODS: One hundred adult (male 50, female 50) patients were studied. The comparison topographic length (in cm) was measured by adding the distance between the right mouth corner and the right mandibular angle to the distance between the right mandibular angle and the center of the sternal manubrium. The new endotracheal tube insertion depth (in cm) was determined by adding the distance between the right mouth corner and the vocal cords, measured with the endotracheal tube itself, to the distance between the thyroid prominence and the manubriosternal joint, and then subtracting 4 cm. After intubation, the endotracheal tube was positioned properly at the right mouth corner and the endotracheal tube tip was evaluated using a fiberoptic bronchoscope at the carina. RESULTS: The distances from the tip of the endotracheal tube to the carina were not significantly different between the methods in the same gender. However, our method allowed endotracheal tube tip placement between 3 cm and 5 cm, above the carina more frequently than the prior method in males. CONCLUSIONS: The new topographical method can be used as a guide to positioning the endotracheal tubes.

Topographical Disorientation in Mild Cognitive Impairment: A Voxel-Based Morphometry Study

BACKGROUND AND PURPOSE: To assess the neural substrates underlying topographical disorientation (TD) in patients affected by mild cognitive impairment (MCI), forty-one patients diagnosed with MCI and 24 healthy control individuals were recruited. METHODS: TD was assessed clinically in all participants. Neurological and neuropsychological evaluations and a volumetric-head magnetic resonance imaging scan were performed in each participant. Voxel-based morphometry was used to compare patterns of gray-matter atrophy between patients with and without TD, and a group of normal controls. RESULTS: We found TD in 17 out of the 41 MCI patients (41.4%). The functional abilities were significantly impaired in MCI patients with TD compared to in MCI patients without TD. Voxel-based morphometry analyses showed that the presence of TD in MCI patients is associated with loss of gray matter in the medial temporal regions, including the hippocampus and parahippocampal cortex, the fusiform gyrus, the inferior occipital gyrus, the amygdala, and the cerebellum. CONCLUSIONS: The findings found in this study represent the first evidence that the presence of TD in patients with MCI is associated with loss of gray matter in those brain regions that have been documented to be responsible for orientation in both neuropsychological and neuroimaging studies.

Topographical disorientation in Alzheimer's disease / Desorientação topográfica na doença de Alzheimer

Topographical disorientation (TD) has not been as extensively studied as other frequent manifestations of Alzheimer's disease (AD). OBJECTIVE: To verify the occurrence of TD and to identify the neuropsychological dysfunctions associated with TD in AD. METHOD: Thirty patients with probable AD, their caregivers and 30 subjects without dementia (controls) were interviewed with a questionnaire and evaluated with tests related to topographical orientation. RESULTS: AD patients, even those with mild dementia, differ from controls in the questionnaire on topographical orientation and in most neuropsychological tests except for tests of spatial working memory, point localization, three dimension and nonsense figure copy. When the performances in the neuropsychological tests of patients with mild or moderate dementia were compared, only landmark recognition and route description were more impaired in moderate dementia. CONCLUSION: TD occurs even in mild dementia of AD, a finding apparently not explained by the impairments of more elementary spatial functions.

Desorientação topográfica (DT) não tem sido tão exaustivamente estudada quanto outros sintomas frequentes da doença de Alzheimer (DA). OBJETIVO: Verificar a ocorrência de DT e identificar as disfunções neuropsicológicas associadas com a DT na DA. Método: Trinta pacientes com DA provável, seus cuidadores e trinta sujeitos sem demência (controles) foram entrevistados com um questionário e testes relacionados à orientação topográfica. RESULTADOS: Pacientes com DA, mesmo aqueles com demência leve, diferiram dos controles no questionário de orientação topográfica e na maioria dos testes neuropsicológicos, exceto nos testes memória operacional espacial, localização de pontos, cópia de figuras sem sentido e de figura em três dimensões. Quando os desempenhos de pacientes com demência leve ou moderada foram comparados, apenas os testes de reconhecimento de marcos e descrição de rotas foram mais comprometidos na demência moderada. CONCLUSÃO: DT ocorre mesmo na demência leve da DA, um achado aparentemente não explicado pelo comprometimento das funções espaciais mais elementares.

Segmentation of Hippocampus in Human Brain MRI Using Watersnakes / 대한의료정보학회지

OBJECTIVE: The algorithm of Watersnakes is used to segment the hippocampus on one slice of MR image. METHODS: This method integrates the watershed transform and the active contour algorithm. The watershed transform, based on mathematical morphology, is powerful and flexible for segmentation. However, it does not allow the characteristics of region boundaries to be included into the way that active contour algorithm do. So, oversegmentation is in the result, even to hippocampus. For watersnakes algorithm, the primitive contour of hippocampus can be obtained using watershed transform. Based on energy-driven, the contour of hippocampus develops into the ultimate result. In the process of energy-driven, the information relating to characteristics of region boundaries is involved. RESULTS: The results of watersnakes showed oversegmentation could be avoided, compared to the results of watershed transform. CONCLUSION: Watersnakes can use the advantage of watershed transform and active contour algorithm to improve the results of segmentation.

The Analysis of Management of Keratoconus Using Contact Lens in Koreans

PURPOSE: To analyze the fitting characteristics of contact lens, according to the clinical findings keratoconus of in Koreans. METHODS: The topographic indices were evaluated in 106 keratoconic eyes of the 53 patients, who had been followed up for at least 1 month, and their fitting pattern parameters retrospectively analyzed. The visual acuity, epithelial erosion, glare, daily lens wearing time, pain and the changes in the topographic indices were evaluated after fitting. RESULTS: The number of eyes fitted with spherical RGP, aspherical RGP and multicurve RGP were 19, 6 and 81 eyes with mean base curve radius (BCR) of 7.67, 7.17, and 6.76 mm, respectively. The Sim K and temporal K 3 mm from the center were significantly correlated with the BCR. 77 eyes achieved visual acuity of 20/30 or better, and the mean daily wearing time was 11.6 hours. Glare and pain were reported in 4 and 7 eyes, respectively, and progression of epithelial erosion was found in 8 eyes. The mean anterior elevation and sim Kmax in lens intolerable eyes were 0.0745 mm and 59.35 D, which were significantly higher than 0.0584 mm and 54.22 D in lens tolerable eyes. No progressive keratoconic changes were observed in the topographic indices for the eyes fitted with the multicurve lenses. CONCLUSIONS: Appropriate fitting guide-lines could be established by analyzing the fitting and clinical characteristics in keratoconus.

Culture of Bovine Retinal Pigment Epithelium: Topographical Differences of Morphology and Growth Rate in Vitro

Cell cultures of adults bovine retinal pigment epithelium(RPE) were propagated from central and peripheral regions of the same eyes to study the topographical differences in cell growth and to compare the differences in growth rate between two areas. The results obtained were as follows: A regional variation in the morpholgy was observed between the RPE from central and that from peripheral regions. Retinal pigment epithelium from central region attached to culture dish more slowly(average 4 days) than those from peripheral region(average 3.5 days) The growth rate of retinal pigment epithelium declined with serial passage in culture. The growth rate of retinal pigment epithelium from peripheral region at the first generation was highest. And there was a statistical difference in growth rate with passing in generation(P<0.05). This study reveals that growth rate and cell activity of RPE from central region are lower than from peripheral region.

Findings of Semiquantitative Analysis of 99mTc-HMPAO Brain SPECT in Cerebral Palsy

It is often difficult, on the basis of clinical examination and conventional investigations, to evaluate the functional impairment of brain in children with cerebral palsy in which early detection remains a challenge. This study was designed to know the usefulness of single photon emission tomography(SPECT) of the brain with technetium-99 m hexamethylpropyleneamineoxime (99mTc-HMPAO) as a semiquantitative method of determination of right-left asymmetries in tracer uptake and a change in antero-posterior regional cerebral blood flow(rCBF) distribution. We investigated 33 children with cerebral palsy aged from 4 months to 48 months(mean 19.3 months). The results were as follows: right to left ratio and regional index of a transverse view were useful to quantify the decrease of tracer uptake in left hemiplegia, but not in right hemiplegia who were all mild in severity, and in tetra- and diplegia in which cerebral lesions were found bilaterally; cortico-cerebellar ratios of a sagittal view were found useful to detect a decrease of rCBF distribution in tetra- and diplegia ,which was not distinct by means of right to left ratio and regional index on transverse view. The results suggest that semiquantitative analysis of 99mTc-HMPAO Brain SPECT would be a valuable complementary tool for determination of topographical involvement in cerebral palsy.

Topographical Morphology of the Lingual Artery in Korean / 체질인류학회지

In order to clarify the topographical morphology of the Korean lingual artery related to clinical problems, authors investigated the morphological variations of the lingual artery through the dissection of the deep layer of head and neck. 61 -sides of Korean adult cadavers (mean age 57.8) were used for this study. The morphlogy of the origin sites of the lingual artery were classified into three types. The cases that the superior thyroid, lingual, and facial artery were originated independently from the external carotid artery were most common (56.3%). Others were the cases that the lingual artery and the facial artery were divided from the linguofacial trunk (31.2%), and the cases that the superior thyroid artery and the lingual artery were divided from the thyreolingual trunk (12.5%) from the external carotid artery, respectively. In the topographical relationships between the first part of the lingual artery and the hyoglossus muscle, the cases that the first part of the lingual artery formed loop posterior to the hyoglossus muscle (41.2%) and the cases that the lingual artery penetrated into the medial aspect of the hyoglossus muscle passing the posterior border of this muscle (66.1%) were observed most frequently. Others were the cases that the lingual artery penetrated into the posterior muscle fiber (18.6%) and the middle muscle fiber (15.3%) of the hyoglossus muscle. The courses of the second part of the lingual artery deep to the hyoglossus muscle could be classified into two morphlogical types. One was that the second part of the lingual artery ran superiorly from the origin site and then turned abruptly towards deep portion of hyoglossus muscle. In these cases, the artery turned upward again at the inside of the muscle, and then reached to the sublingual region (42.6%). The other cases were that the lingual artery ran gradually to the medial and superior aspect of the sublingual region (57.4%). The prevalency of the sublingual arteries originating from the lingual arteries was 59%. Taken all together, authors concluded that the mouth floors of Korean are supplied by both the lingual and facial artery. So, performing the hemostatic procedures in the mouth floor region, the surgeon must take a topographical anatomy of this region related the arterial supply into account.
