The castor bean is an oil seed crop, and the oil present in the seeds has several industrial applications. Recently it has been suggested to be used as a renewable fuel (Biodiesel). As a consequence the crop has assumed a relevant ecological and economic importance. Two field studies were conducted in 2003, 2004 and 2005, with the objective of evaluating the behavior of castor bean grown at different times and spacing and under irrigated and rainfed conditions. The experiments were carried out at the "Fazenda Experimental do Vale do Curu", belonging to the Universidade Federal do Ceará, Brazil. In the first experiment the castor plant cv. BRS 149 Nordestina was sown at four different times of planting combined with two irrigation regimes. In the second experiment, two cultivars were evaluated (BRS 149 Nordestina and Mirante 10) seeded in three plant spacing and two different times. Irrigation was more profitable at the beginning of the cycle, prior the rain season than at the end of the rain period, at the end of the plant growth cycle. The combination of the anticipation of the sowing in January of 2004 with the use of irrigation promoted increments in the seed yield and number of racemes for plant and higher weight and number of fruits per raceme. Irrigation yielded better results when was associated with the earliness of planting, as compared with application of water at the end of the raining season. The seeds of the secondary and tertiary racemes possessed greater oil content and seeds weigh. When sowed in December of 2003 the primary racemes produced very light seeds. In the experiment of 2005 the following results were observed: the combination of anticipation of sowing with irrigation promoted increases of the height of the plant, number of lateral branches and the number of internodes, delayed flowering and increased grain yield. Under rain red conditions the number the number of fruits per raceme was reduced. Secondary racemes were responsible for the higher proportion of total seed yield, followed by the tertiary racemes. The cv. BRS 149 Nordestina showed higher seed weigh and oil content. Under irrigation condition the weigh of the seeds increased, independent of the spacing or cultivar used. The early planting associated with the irrigation practice reduced the oil content of the seeds.

The use of the medicinal plants is one of the oldest weapons maids for the treatment of the human illnesses and it is very already known regarding its use on the part of the popular wisdom. The sacred grass (Cymbopogon citratus (DC.) Stapf) it is a medicinal and aromatic plant, belonging to the family Poaceae. This work had as objective determines the planting spacing, the cut height and the ideal age of first cut, seeking to obtain the largest income in essential oil. For this, was settled in December of 2004, an experiment, in the area of Experimental Farm of the valley of Curu (F.E.V.C.), belonging to the Agrarian Sciences Center of the Federal University of Ceará, located in the municipal district of Pentecoste/Ce. The referred experiment was composed of the following treatments: three spacings (0,5m x 0,5m; 0,5m x 0,8m and 0,8m x 0,8m); three different times from first cut (04, 06 and 08 months) and two cut heights (15cm and 30cm of the soil), with 04 repetitions, being accomplished more two cuts in each treatment in intervals of 04 months. The used experimental delineation was in blocks at random in factorial outline 3 x 3 x 2. The obtained data were transformed for productions by hectare. As for the cut age, the best production of essential oil was obtained to the six months, the same if not verifying for the matter dries that had continuous growth. The begin of the crop to the six months after the planting in the 0,5m spacing between plants and 0,5m among rows promoted the largest production of dry matter and of the essential oil of sacred grass. About the cut height, as much the biomass production as the income of essential oil they were higher in the height of 15cm of the soil. Therefore, the C. citratus should be cultivated in the spacing 0,50m x 0,50m, picked the height of 15cm of the soil, with first harvest to the 6 months of age and consecutive cuts every four months to obtain the largest income in essential oil.

As maiores capturas da lagosta Panulirus laevicauda (Latreille), ocorrem na costa do nordeste brasileiro. A relação entre o comprimento (L) e a idade (t), definida como curva de crescimento, é de fundamental importância para o estudo da dinâmica de populações, e portanto, para a investigação pesqueira. No presente trabalho, utilizamos dados de comprimento do abdómen de lagostas da espécie Panulirus laevicauda (Latreille), capturadas em águas costeiras do Estado do Ceará (Brasil), para o cálculo de nova curva do seu crescimento e idade. A estimativa do comprimento máximo teórico, anteriormente feita por Santos & Ivo (1973) , não está de acordo com as observações de campo, conforme referência dos próprios autores. No presente trabalho, foram utilizados apenas os dados das amostragens realizadas nos meses de janeiro, abril, julho e outubro de cada ano, agrupados em intervalos de 0,5 cm, num total de 2.469 indivíduos (tabela I). Não foram considerados os sexos.

Sour sop, Annona muricata, is an Annonaceae specie crop that is growing gradually in the Northeast region of Brazil. Although it is difficult to handle, considering the control of its diseases and pests that occur to it is one in such a way how much complicated, this fact does not intimidate the producers of pulps, ices cream, juices, therefore the promising consuming market causes profit. The fruit borer, Cerconota anonella, and the seed borer, Bephratelloides spp are the most important pests that attack sour sop orchard. The seed borer is a very complex group which is found all growing areas around the world. Both represent the most important pests for their damage to the fruit and loss to growers. In spite of the economic importance played by sour sop, scientific studies to improve its growing methods are scarce. Considering these introduction, with the objective to evaluate the potential of natural and synthetic products in the control of the fruit and seed borers, an experiment was conducted in the Experimental Station of the Embrapa in Pacajus - Ce, from March to September of 2005. A completely randomized design was used in a 4x2x2 factorial, where four products had been used: natuneem, watery extract of Licania rigida, endosulfan (Thiodan CER Bayer CropScience) and Deltamethrin (Decis 25 CER, Bayer CropScience); two intervals of application; and fruit uncovered and covered with tissue-not-tissue (TNT) G-16, adding up to 18 treatments, each one with 9 replications. The Tukey test was used to compare the averages gotten for both insects, but it was necessary to use the Dunnet test in the results of fruit borer. For both pests the Abbbott test of efficiency was used. For the fruit borer, the covering fruit and application intervals did not affect the outcome of results. Deltamethrin and Endosulfan attained the highest efficiency for controlling the fruit borer (%E = 50,60). There were no differences on intervals of application and covering the fruit. The Treatments don’t showed satisfactory efficiency. On the order hand for the seed borer, covering the fruit was also significant. The Test of efficiency of Abbott pointed those treatments Licania extract applied every 28 days and uncovered fruit; endosulfan applied every 14 days + covered fruit; endosulfan applied every 28 days + covered fruit; deltamethrin applied every 14 days + covered fruit; deltamethrin applied every 14 days + uncovered fruit; deltamethrin applied every 28 days + covered fruit and deltamethrin applied every 28 days + uncovered fruit as higher percentages (%E = 39,51). The performance of the treatments against Bephratelloides spp. did not reached satisfactory percentage of efficiency.

The goals of this dissertation are study of sodium hypochlorite and chlorhexidine as irrigants, through a literature review, evaluate and quantify, by means of bacterial culture, the antibacterial effect of biomechanical preparation and pulp-based hydroxide calcium with or without 1% chlorhexidine on bacteria in root canals of permanent teeth after necrotic injury, as well as verifying the presence of microorganisms Fusobacterium nucleatum and Black Pigmented Bacillus in these teeth. The sample consisted of 13 teeth, totaling 11 patients. Microbiological samples were taken after the coronal opening (A1), after root canal preparation (A2), followed by the use of intracanal dressing (A3) and 72 hours of the removal of the medication (A4). The samples were collected sequentially introducing three sterile absorbent paper cones inside the root canal for one minute. In A1, 100% of samples were positive, and the average colony forming units (CFU) of 7.7 x 104. In the second collection (A2), 5 / 13 samples were positive, with an average of 1.7 x 103 CFUs. After use of the medication (A3), 4 / 13 samples were positive, averaging 3.3 x 103 CFUs. A4, 6 / 13 samples were positive, with an average of 1 x 104 CFUs. Between A1 x A2, A3 and A1 x A1 x A4, we observed a reduction of CFUs was statistically significant (p <0.001). We were unable to observe a statistically significant difference (p> 0.05) among the other samples. We conclude that chemo-mechanical performs its antibacterial function by significantly reducing the number of micro-organisms from the main channel, but calcium hydroxide and its association with chlorhexidine 1% had no statistically significant difference, having an antibacterial effect limited not being able to prevent bacterial growth after its use as an intracanal medication.

The objective of this study was to verify the presence of maxillary morphologic parameters on the Obstructive Sleep Apnea Syndrome (OSA) The sample was consisted on maxilla dental models of 23 individuals (11 males and 12 females) with the polyssonographic diagnosis of mild SAOS, 34 individuals (17 males and 17 females) with moderate SAOS and 17 individuals with severe SAOS (14 males and 3 females) Measures of maxilla dental models of 50 young Brazilians were used for the control group, both males and females and with normal occlusion and without any indication OSA The results found show that the maxillary morphologic parameters evaluated didn’t show the association with the apnea/hypopnea index (AHI) but minor transversal dimensions of the maxilla mainly at the level of the molars associated to the increase of the dessaturation of oxyhemoglobin (minSaO2) The individuals with OSA also presented maxilla transversal dimensions narrower and more height on the palate at the region of pre-molars and molars when compared to the control group.

Aim: Compare the effectiveness of four different substances, e.g., 1% chlorhexidine, 3% vancomycin, 10% vancomycin and 1,23 % sodium fluoride, in the reduction of Mutans streptococci (MS) in children with dental caries. Methods: Seventy one children, with ages between 4 and 8 years, were randomly assigned to one of four groups. The antimicrobial agents were prepared as gels and applied during 6 consecutive days, in previously fabricated custom trays. Saliva samples were collected before treatment application (D1), on the last day of treatment (D6), 15 (D15) and 30 days from day 1 (D30). For microbiological analysis samples were placed on MSB Agar medium, incubated at 37o C, under microaerophilic condition for 48 hours and then reading was performed in order to identify number of colony forming units (CFU)/mL. Results: When comparing D6 and D1 the following results were observed: Vancomycin 10% (p = 0.0008) and Chlorhexidine (p = 0.0001) expressed significantly lower bacterial counts. Comparisons between D30 and D1 revealed that Fluoride and Chlorhexidine demonstrated a return to baseline values (D1), while Vancomycin 3% (p = 0.004) and 10% (p = 0.003) generated significantly higher counts in D30 than baseline. At D6 Vancomycin 10% (p = 0.0001) and Chlorhexidine (p = 0.000) expressed the lowest bacterial counts when compared to Fluoride (Mann-Whitney test), with no statistically significant difference between these two groups (p = 0.24) being observed. Conclusions: In the present study, after 6 consecutive days of topical administration, 1% Chlorhexidine gel demonstrated to be as effective as 10% Vancomycin gel in salivary MS reduction in children with dental caries. However, 1.23% Sodium Fluoride and 3% Vancomycin gel demonstrated to be equally ineffective. In conclusion, the use of a 1% Chlorhexidine gel during 10 minutes, for 6 consecutive days demonstrated a great efficacy in salivary MS reduction in children with caries, not leading to bacterial counts higher than what was initially observed.

Monitoring and evaluation of health services are indispensable steps in the process of implementation of health policies. Trustworthy health information is relevant to subsidize the planning and the decision-making. Family’s Health Strategy, understood as the primary access mechanism of the users to health actions, provides data related to the implementation of activities within its scope through the information systems. This study aimed to analyze the Oral Health Indicators of the Primary Attention Pact within the State of Ceará, checking the percentage of the population assisted by the Family’s Health Strategy and Oral Health Program, the presentation of Oral Health Indicators in the historical series proposed and how the information, which generates indicators, is provided by the professionals in charge. This work consisted of two stages. In stage 1 it was compiled data on the population’s coverage of the actions of the Family’s Health Strategy and Oral Health Program and the Oral Health Indicators of the Primary Care recommended by the Ministry of Health within the State of Ceará. It was used information concerning the historical series between the years 2001 and 2007, when the Ministry of Health began to fund cities, as an incentive for inserting dentist surgeons in the Family’s Health teams in Brazil. These data were obtained through the website of the Ministry of Health and complemented by the Oral Health Care Department of the Secretary of Health of the State of Ceará. They were arranged in Excel charts and it was considered statistically significant the differential analyses whose p-value was less than 0.05. The data were processed in the program so-called SPSS (Statistical Package for the Social Sciences). In stage 2, it was used an instrument (questionnaire) applied to dentist surgeons who participate in the Family’s Health Strategy in Ceará, where they were asked about their knowledge about the Oral Health Indicators and how they used to inform the Oral Health actions that they carried out daily in the Basic Units of Health Family and some other social spaces where they worked in. The stage 1 data were analyzed using linear regression and association between variables. It was verified that there was percentage growth of population’s coverage of the historical series of the Family’s Health Teams and Oral Health was statistically relevant. There was no statistically significant improvement in the Oral Health indicators, giving evidence of the stagnation of the members during the historical series. It was noticed that there are misunderstandings about the interpretation of the indicators and in the registry of the data related to the Oral Health actions by dentist surgeons operating in the Family’s Health Strategy and orientation of Ministry of Health, with the necessity of implementation of measures of permanent training to clarify aspects concerning the Oral Health Indicators.

Periodontitis is a disease characterized by leukocyte influx, loss of connective tissue and bone resorption. Statins are drugs widely used to hyperlidemia treatment, in which stand out Atorvastatin (ATV) due to its important pleiotropic effects, such as antiinflammatory activity and anabolic bone capacity, with great potential to modify chronic inflammatory disease course. In this way the aim of this work was to evaluate the aniinflammatory effect of ATV, through ligature-induced periodontitis model in rats. Wistar male, located in experimental groups: control (0.9% Saline), and 5 subgroups (ATV 0.3, 1, 3, 9 or 27 mg/kg), given orally daily, 30 min before nylon thread 3.0 aroud cervix of second left upper molars during 11 d, when then, rats were sacrified, and the following parameters were analyzed: 1) alveolar bone loss (ABL), evaluated through morphometric, histologic and radiographic studies; 2) Sistemic evaluation through a) leucograms performed before and after ligature (6h and 2, 7, and 11 d); b) corporal mass variation; c) of liver and kidney analysis, by serum biochemical dosage and histological study; and d) serum evaluation of Bone-Specific Alkaline Phosphatase (BALP). Animals submitted to 11 d periodontitis presented intense bone resoption. Low dose of ATV (0.3 mg/kg) was not able to prevent ABL (p>0.05), meanwhile the other dose ATV (1, 3, 9 or 27 mg/kg) were , in a significant way able to reduce ABL by 35%, 39%, 53%, 56%, respectively. Such inhibition was corroborated by histological analysis where was observed that ATV (27 mg/kg) caused greater periodontal tissue preservation [Mean 1.5 (0-2)], when compared to Saline [Mean 3 (2-3)] . In addition, animals submitted to periodontitis presented a significant reduction on periodontal radiographic density (58%). ATV (1, 3 ou 9 mg/kg) preserved such density in 5%, 9% e 20%, respectively. The leucogram of animals submitted to periodontitis presented leukocytosis peak on the 6th h mediated by neutrophils and new leukocytosis after 7th d due mononuclear cells. ATV (27 mg/kg) was able to reduce leukocytosis, decreasing neutrophils or mononuclear cells respectivelly (p<0.05), as well as, it was able to reduce initial corporal mass loss seen in periodontitis. Serum biochemical and histological analysis of liver and kidneys of animals with 11 d periodontitis treated with (ATV 27 mg/kg) or not (Saline), did not show alterations (p>0.05). It was observed a raise on serum BALP dosage variation of animals with 11 d periodontitis (Saline: 63.4±10.8 U/l), while ATV (27 mg/kg) prevented that increase (13.6±3.5 U/l) (p<0.05).In this way, the results demonstrated that this periodontitis model in rats reproduced the main aspects of periodontal disease in humans, and ATV reduced periodontal destruction, without cause significant alterations on liver and kidneys, besides of keeping BALP activitys, what suggests that ATV may be an important pharmacological approach as an adjuvant to periodontal therapy, to be evaluated clinically, due to its efficacy and safety.

A wide range of diseases can affect the oral cavity, from developmental defects to metastasizing malignant neoplasms. The knowledge on Oral Pathologies`s prevalence helps the clinician making differential diagnosis. The aim of this study was to perform an epidemiological survey of oral lesions in five anatomopathological laboratories in Fortaleza, Ceará, Brazil. Methods: The sample was obtained from histopathology reports of oral lesions diagnosed between the years of 2001 to 2005 in five anatomopathological laboratories. Data regarding sex, race, age, anatomical site and histopathological diagnosis were registered. Lesions were categorized in non-neoplastic, neoplastic and descritive reports. Results: During the five-year period, 6231 oral lesions reports were collected, 41,41% from private laboratories and 58,59% from public laboratories. Female were more affected, with a male:female ratio of 1:1,68. Lesions occurred in a wide age range, varying from 0 to 100 years old, with an incidence peak between 31 to 60 years. Non-neoplastic lesions represented 64,89% of cases, with inflammatory/reactive lesions being the most prevalent group, followed by inflammatory lesions of salivary glands, cysts and non-atypical epithelial hyperplasia. Neoplastic lesion represented 30,80% of cases, 59,52% benign, 32,45% malignant and 8,03% pre-malignant lesions. Fibroepithelial hyperplasia was the most common lesion in this study and squamous cell carcinoma was the most prevalent malignant neoplasm, with 23,14% and 8,52%, respectively. Conclusions: Oral lesions were more common among female’s reports, in economically active age, mainly represented by inflammatory/reactive lesion. Although, the occurrence of inflammatory/reactive lesions was high, the prevalence of malignant neoplastic and pre-malignant lesion was significant. There dental surgeon must know about the occurrence of such lesions, and public health politics for prevention and early diagnose must be enfasized.
