Enraizamento de manjericão em diferentes substratos e doses de cinzas / Stem rooting of basil in different substrates and doses of ash

O trabalho teve como objetivo avaliar a influência de doses de cinzas em diferentes substratos no enraizamento de estacas de manjericão (Ocimum basilicum). O experimento foi conduzido em área do Núcleo de Capacitação e Pesquisa da Universidade Federal Rural da Amazônia, em Belém. Foi utilizado o delineamento experimental inteiramente casualizado, em esquema fatorial 2 x 5, constituído pelas combinações entre os fatores substratos (casca de arroz carbonizada e casca de castanha triturada) e acréscimo de cinzas (5 mL e 10 mL de cinza de casca de arroz, 5 mL e 10 mL de cinza de casca de castanha e sem cinza) com 4 repetições. Cada unidade experimental foi constituída por 10 estacas, num total de 400 estacas. Foram avaliadas as características percentual de enraizamento de estacas, número e comprimento de raízes. Não houve interações significativas entre os fatores avaliados (substrato e cinzas). Entre as características avaliadas o substrato casca de arroz carbonizada apresentou diferenças apenas no comprimento da raiz e no número de raízes, enquanto as dosagens de cinzas apresentaram diferenças apenas no percentual de enraizamento. O trabalho permitiu concluir que as dosagens de cinzas apresentaram efeito positivo sobre o enraizamento das estacas de manjericão, assim como o substrato a base de casca de arroz carbonizada propiciou melhores condições para o desenvolvimento das raízes. Assim, a casca de arroz é uma alternativa totalmente viável, pois além de apresentar características apropriadas para o enraizamento também possui baixo custo de aquisição, estando ao alcance de muitos produtores.

The study aimed to evaluate the influence of ash doses on different substrates on the stem rooting of basil (Ocimum basilicum). The experiment was conducted in the area of core training and research at the Universidade Federal Rural da Amazônia, in Belém, used a completely randomized design, factorial scheme 2 x 5 consisting of the combinations of the factors substrate (carbonized rice husk and bark brown ground) and increase ash (5 mL and 10 mL of rice husk ash 5 mL and 10 mL of husk ash and brown bark no gray) with four repetitions. Each experimental unit consisted of 10 cuttings, a total of 400 cuttings. Was evaluated the characteristics percentage of rooting, number and length of roots. There was no significant interaction between the factors evaluated (substrate and ash). Among the characteristics evaluated the carbonized rice showed only differences in root length and root number, while the levels of ash showed only differences in rooting percentage. The study revealed that the dosages of ash had a positive effect on rooting of cuttings of basil, as well as the substrate prepared with rice hulls provided the best conditions for root development. Thus, the rice husk is an alternative, as well as presenting features suitable for rooting also has a low cost of acquisition, being within reach of many producers.

[Relationships between the coronal suture and the sulci of the lateral convexity of the frontal lobe: neurosurgical applications]. / Relações da sutura coronária com os sulcos da face súpero-lateral do lobo frontal: aplicações neurocirúrgicas.

An anatomical study of the relationships between the coronal suture and the sulci of the convexity of the frontal lobe was accomplished in seven cephalic segments. The pre-central and central sulci are, respectively, 26,5 mm and 40,5 mm behind the bregma and 15,0 mm and 35,5 mm behind the pterion. The use of the coronal suture as point of reference, and especially, its relationship with the sulci of the lateral surface of the frontal lobe, allows to determine the projection on the cranium of the superficial cerebral lesions with the purpose to delimit the surgical access and to guide the approach to the cerebral convexity.

[Congestive brain swelling in victims of fatal road accident. Frequency and association with other head injury lesions]. / Tumefação cerebral congestiva em vítimas fatais de acidente de trânsito. Frequência e associação com outras lesões cranioencefálicas.

A morphological study, macro and microscopical, was made of brain lesions in 120 victims of fatal road traffic accidents. Congestive brain swelling occurred in 21 (17.5%) patients. Owing to the brain swelling that increases the brain volume, an increase of brain weight was also observed. Brain contusion was the most frequent lesion associated with congestive brain swelling (76.2%), while the intracranial haematomas were observed in almost half of the cases.

[Burst lobe in victims of fatal road traffic accident. Frequency and association with other head injury]. / Explosão lobar em vítimas fatais de acidente de trãnsito. Frequência e associação com outras lesões encefálicas traumáticas.

A morphological study, macro and microscopical, was made of brain lesions in 120 victims of fatal road traffic accidents. Burst lobes were identified in 12 (10.0%) of the patients. It occurred in the frontal lobe in 6 (50.0%) patients, in the temporal lobe in 2 (16.7%) and in both lobes in 4 (33.3%) patients. A skull fracture occurred in 8 (66.7%) patients and intracranial hypertension occurred in half of cases. Nine patients were admitted in coma and three patients died immediately after the road traffic accident. All cases of burst lobes were associated with diffuse axonal injury, which explains the severe alteration of consciousness observed at the patients' admission.

Survey of Parvovirus B19 Infection in a Cohort of Pregnant Women in Belém, Brazil.

In our study, 300 pregnant women were screened for the presence of human parvovirus B19 IgG and IgM antibodies by an enzyme-linked immunosorbent assay (ELISA). Overall, 253 (84.3%) were found to be IgG-positive and IgM-negative (IgG+gM ), 42 (14%) had neither IgG nor IgM antibodies (IgG /IgM ) and 5 (1.7%) were both IgM- and IgG-positive (IgG+/IgM+). Maternal serology was performed routinely for cytomegalovirus, rubella, toxoplasmosis and syphilis. All IgG /IgM and IgG+/IgM+ women were followed up till the time of delivery, venous blood sample being taken monthly from each one; one IgG /IgM mother seroconverted to IgG+/IgM and B19 DNA was detected by nested polymerase chain reaction technique (PCR) in her serum. All babies born to IgG+/IgM+ mothers (and from that who seroconverted) were IgG+IgM , no B19 DNA could be detected in their sera and no adverse effects were documented either by ultrasonographic examination or the detection of maternal serum alpha-fetoprotein. While 5 of these mothers delivered normal children at term, one gave birth to a premature (low-weight) baby who developed severe anemia and had convulsions; this mother was found to have toxoplasma-specific IgM. As based on serial testing of sera, it is notable that B19 IgM may last up to six months. Our data indicates a low incidence rate of B19 infection in pregnancy in our region, at least during interepidemic periods. In addition, it suggests that recent B19 infection represents a low risk for the development of adverse fetal outcomes.

[Intracranial hypertension in victims of fatal traffic accidents]. / Hipertensão intracraniana em vítimas fatais de acidente de trânsito.

A morphological study, macro and microscopical, was made of brain lesions in 120 victims of fatal road traffic accidents. Parahipoccampal hernia, Duret haemorrhage and infarction in the medio-basal occipital lobe, clear evidence of raised intracranial pressure, occurred in 43 (35.8%) patients. The increased intracranial pressure from the head injury is caused by brain swelling and by intracranial haematomas. In this series 3 cases of extradural haematomas (7.0%), 9 of subdural haematomas (20.9%), 6 of intracerebral haematomas (14%), 6 of burst lobe (14%) and 9 of brain swelling (20.9%) were observed.

[Cerebral contusion in victims of fatal traffic accidents. Frequency and association with other craniocerebral lesions]. / Contusão cerebral em vítimas fatais de acidente de trânsito. Frequência e associação com outras lesões cranioencefálicas.

A morphological study, macro and microscopical, was made of brain lesions in 120 victims of fatal road traffic accidents. Contusions of the brain were identified in 67 (55.8%) of the patients. The contusions especially affected the orbital surfaces of the frontal lobes (27.8%) and the temporal poles (19.8%). The recent brain contusion was associated with a skull fracture in 70.1% of the cases and with a diffuse axonal injury in 89.5%. These can be explained by the association of contact and inertia from the road traffic accidents. Old contusions were identified in six patients (5.0%).

[History of neurology in Belo Horizonte, Brazil]. / Historia da neurologia em Belo Horizonte.

The birth and the evolution of Neurology in Belo Horizonte, Brazil, is described focusing the influences of the neurological school of Rio de Janeiro and the world neurological context. With the foundation of the Faculdade de Medicina de Belo Horizonte, the specialty begins embryonarily with neuropsychiatrists. José Geraldo Albernaz and Gilberto Belisário Campos in the 50's and 60's of this century began the modern neurology in Belo Horizonte.

Extradural haematoma and diffuse axonal injury in victims of fatal road traffic accidents.

Seven cases of victims of road traffic accidents with extradural haematoma (EH) and diffuse axonal injury (DAI) are reported. Such cases are part of a total of 120 victims of fatal road traffic accidents that were subjected to pathological study. The association of the two lesions occurred in 5.8% of the patients and all cases of EH were associated with DAI. The latter explains the immediate coma (absence of lucid interval) and the grave prognosis for all seven patients. It was noted that EH is relatively infrequent in road traffic accidents, but in such cases it is more severe since it is frequently associated with DAI and immediate coma.

[Pavie: one of the pioneers of modern medicine in Brazil]. / Pavie: l'un des pionniers de la médecine moderne du Brésil.

This is a brief biography and analysis of Pavie's medical work, who at the beginning of our century, practiced medicine in the broad area of Minas Gerais (Brazil). As a consequence of his great professional activity and correspondence with European medical centres, he developed a highly sophisticated practice of medicine for the time, in a poor region far from any brazilian urban centres resources. The success of Pavie's innovative work became one of the first accounts of true modern medical pioneering in Brazil.

[Subdural effusions in children. Pathophysiology and treatment]. / Coleção subdural na criança. Fisiopatologia e tratamento.

Nine children harboring subdural effusions were treated by subduro peritoneal shunt. These patients were followed-up by CT scans. The area of the subdural effusions was measured by quantitative morphology with a planimeter. With the surgical treatment, the subdural effusion disappeared completely or near completely in 8 patients. The patient's functional state were excellent in 4, good in 3 and bad in 2 in the postoperative follow-up. We aldo reviewed the literature as far as the pathophysiology and the treatment of the subdural effusions are concerned.

Tumoral form of cerebral schistosomiasis mansoni. A report of four cases and a review of the literature.

We describe four cases of the tumoral form of cerebral schistosomiasis mansoni. The patients had symptoms of increased intracranial pressure and focal neurological signs that varied according to the site of the lesion. Computerized tomography showed a hyperdense, enhancing lesion located in the cerebellum (2 patients), frontal lobe and thalamus (1 patient), and temporal subdural region (1 patient), with associated mass effects. The lesion was resected in three patients and a stereotactic biopsy was performed in one. Histopathologic specimens of all four patients revealed multiple schistosomal granulomas in various evolutive phases. Two of these patients differ from previously described cases; one because of the subdural location of the lesion, mimicking a meningioma, and the other one because two lesions were present.

Achados anátomo-patológicos em 120 vítimas de acidentes de trânsito / Anatomopathological findings in 120 traffic accidents victims

Realizou-se o estudo das lesoes encefálicas em 120 vítimas fatais de acidente de trânsito, tendo-se verificado baixa sobrevida média e alta freqüência de lesoes cranioencefálicas e extracraniais. Relativamente às casuísticas análogas referentes a traumas cranianos fechados de diferentes origens, observou-se baixa freqüência de lesoes primárias focais (fratura de crânio, contusao cerebral e hematomas intracranianos) e alta de lesoes primárias difusas (lesao axonal difusa e lesao vascular focal múltipla). A lesao axonal difusa (LAD) foi encontrada em 75,8 por cento dos encéfalos, sendo do primeiro grau em 17,6 por cento; do segundo grau em 53,8 por cento; e, do terceiro, em 28,6 por cento. Apesar da distribuiçao difusa que caracteriza esta lesao, ocorreu comprometimento preferencial das formaçoes inter-hemisféricas e da porçao rostral do tronco encefálico, geralmente de forma lateralizada.
