Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

O bicudo-da-cana-de-açúcar, Sphenophorus levis (Coleoptera: Dryophthoridae), é uma importante praga em canaviais do Estado de São Paulo. Suas larvas destroem o rizoma da planta, causando prejuízos de até 30 t ha-1 ano-1 de cana. Três experimentos de campo foram conduzidos para avaliar a eficácia de nematoides entomopatogênicos e de inseticidas químicos no controle do bicudo-da-cana-de-açúcar e do escarabeídeo Leucothyreus sp. O primeiro consistiu de 10 tratamentos: 1) tiametoxam (Actara 250WG) 500 g ha-1 de produto comercial (p.c.); 2) tiamethoxam 1,0 kg ha-1 p.c.; 3) tiametoxam 1,5 kg ha-1 p.c.; 4) Steinernema brazilense 10(8) juvenis infectivos (JI) ha-1 + tiametoxam 250 g ha-1 p.c.; 5) S. brazilense (10(8) JI ha-1) + tiametoxam 500 g ha-1 p.c.; 6) Heterorhabditis indica (10(8) JI ha-1) + tiametoxam 250 g ha-1 p.c.; 7) H. indica (10(8) JI ha-1) + tiametoxam 500 g ha-1 p.c.; 8) S. brazilense (10(8) JI ha-1); 9) H. indica (10(8) JI ha-1); e 10) Testemunha. No segundo, foram considerados cinco tratamentos: 1) tiametoxam (Actara 250WG) 800 g ha-1 p.c.; 2) fipronil (Regente 800WG) 250 g ha-1 p.c.; 3) S. brazilense (10(8) JI ha-1); 4) S. brazilense (10(8) JI ha-1) + tiametoxam (Actara 250WG) 200 g ha-1 p.c.; e 5) Testemunha. O terceiro incluiu todos os tratamentos do segundo experimento, mais a mistura S. brazilense (10(8) JI ha-1) + fipronil (Regente 800WG) 62,5 g ha-1 p.c. Todos os tratamentos com inseticidas e nematoides proporcionaram maior produção de cana, quando comparados às respectivas testemunhas, que foram mais danificadas por S. levis, mas sem diferenças significativas. O nematoide S. brazilense foi mais eficaz no controle deste inseto, quando comparado com H. indica, mas sem diferenças significativas. S. brazilense proporcionou 50% de controle das larvas de Leucothyreus sp., e os melhores tratamentos para controle deste inseto foram as misturas do nematoide com fipronil (78%) e tiametoxam (83%).
The sugarcane billbug, Sphenophorus levis (Coleoptera: Dryophthoridae), is an important pest of sugarcane crops in the São Paulo State, Brazil. Their larvae damage plants rhizome, causing losses of up to 30 t ha-1 year-1 of sugarcane. In order to evaluate the effectiveness of entomopathogenic nematodes and chemical insecticides against the sugarcane billbug and the scarab beetle Leucothyreus sp., three field trials were carried out in Brazil. For the first one, 10 treatments were considered: 1) thiametoxan (Actara 250WG) 500 g ha-1 of commercial product (c.p.); 2) thiametoxan 1.0 kg ha-1 c.p.; 3) thiametoxan 1.5 kg ha-1 c.p.; 4) Steinernema brazilense 10(8) infective juveniles (IJ) ha-1 + thiametoxan 250 g ha-1 c.p.; 5) S. brazilense (10(8) IJ ha-1) + thiametoxan 500 g ha-1 c.p.; 6) Heterorhabditis indica (10(8) IJ ha-1) + thiametoxan 250 g ha-1 c.p; 7) H. indica (10(8) IJ ha-1) + thiametoxan 500 g ha-1 c.p.; 8) S. brazilense (10(8) IJ ha-1); 9) H. indica (10(8) IJ ha-1); and 10) Control. The second one consisted of five treatments: 1) thiametoxan (Actara 250WG) 800 g ha-1 c.p.; 2) fipronil (Regente 800WG) 250 g ha-1 c.p.; 3) S. brazilense (10(8) IJ ha-1); 4) S. brazilense (10(8) IJ ha-1) + thiametoxan 200 g ha-1 c.p.; and 5) Control. In the third one, all treatments already mentioned for the second trial plus the mixture S. brazilense (10(8) IJ ha-1) + fipronil (Regente 800WG) 62.5 g ha-1 c.p. were considered. All treatments with the insecticides and nematodes provided higher sugarcane yield, when compared to their respective controls, which were most damaged by S. levis, but without statistical significance. S. brazilense was more efficient on controlling this pest, if compared to H. indica, but without statistical significance. S. brazilense provided a 50% control of Leucothyreus sp. larvae, meanwhile the best treatments against this scarab were the mixtures of this nematode with fipronil (78%) and thiametoxan (83%).

OBJECTIVE: Ions, particularly calcium ions, play an important role in ischemia-reperfusion cell injury. In this study, we investigated the action of verapamil on the mitochondrial function of kidneys submitted to ischemia without blood reperfusion in order to study isolated early and late ischemic effects. MATERIALS AND METHODS: 44 rats were submitted to bilateral warm renal ischemia for 30 minutes. The kidneys were then immediately reperfused with saline or Euro-Collins (EC) solution, with and without previous administration of 0.35 mg/kg of verapamil. Mitochondrial function was assessed at the end of renal perfusion and after 24 hours of cold preservation. RESULTS: In kidneys perfused with saline, verapamil allowed a significant early preservation of state III mitochondrial respiration, a result that was no longer evident after 24 hours. In kidneys perfused with EC solution, verapamil did not change state III for either early or late evaluations. Comparison of the groups showed that the results obtained for kidneys perfused with EC were always superior to those obtained for the saline group, except for the initial analysis of kidneys treated with saline and verapamil, which showed results similar to those obtained with EC perfusion alone. CONCLUSION: Administration of verapamil before warm ischemia provides partial and short-lasting functional protection of the mitochondrial function in kidneys perfused with sodium rich saline. With Euro-Collins solution, verapamil did not show any additional beneficial effect. This fact permits us to conclude that protective action is effective only under conditions that facilitate increased sodium uptake and/or potassium loss.

INTRODUCTION: The treatment of benign prostate hyperplasia (BPH) presents 2 options: medical or surgical, and there are doubts about what is the best treatment since 80% of patients who undergo surgery become asymptomatic and 10 to 40% of those under medical regimen undergo surgery within a 5 years period. It is difficult to assess the actual costs of treating BPH in Brazil due to several factors, among them regional particularities and the scarcity of current statistical data. PATIENTS AND METHODS: Recently, in the Ribeirão Preto area, São Paulo, Brazil, the IPSS (International Prostatic Symptoms Score) and quality of life were verified in 934 volunteers. It was determined the percentage of individuals with ages ranging from 40 to 79 years with moderate symptoms (score 8-19) and with severe symptoms (score 20-35), values for which are indicated medical and surgical treatment, respectively, according to the Brazilian Society of Urology consensus on BPH. Data on Brazilian population in that age range were obtained from the Brazilian Institute of Geography and Statistics referent to the year of 2000. It was determined the number of patients, according to the criteria above, subjected to either one of the treatments mentioned. Surgical costs of prostate transurethral resection were researched according to Unified Health System - SUS tables (US$ 173) and of Brazilian Medical Society - AMB with a mean cost in 3 hospitals of US$ 933. Drug costs were calculated by the annual mean price (US$ 355) of 4 alpha-blockers (tamsulosin, alfuzosin, doxazosin and terazosin). RESULTS: The estimated population for medical treatment was 5,397,321 individuals, with a cost corresponding to US$ 1,916,489,055.00. The estimated population for surgical treatment was 2,040,299 men, what would represent a cost of US$ 353,291,204.00 based on the SUS table and of US$ 1,904,279,066.00 based on AMB with hospital expenses included. CONCLUSION: All theses facts induce us to predict that the treatment of BPH in a not-so-far future can become a public health problem for Brazilian society, since the current estimate would be, approximately, costs around 2.26 - 3.83 billion dollars, added by the yearly increase in the risk population (24.99%) for the group under medical treatment and over the non-operated amount of the surgical group.

INTRODUCTION AND OBJECTIVES: Chagas' disease causes specific parasympathetic denervation and in its digestive clinic form promotes also functional alterations in bladder. Thus, the aim was to investigate the existence of balance between sympathetic and parasympathetic systems in lower urinary tract, as occurs in other organs. We verified the urethral closing pressure before and following parasympathetic stimulus. PATIENTS AND METHODS: For that, the urethral closure pressure was studied before and after the injection of 5 mg of bethanechol chloride subcutaneously in 28 voluntary female patients, divided into 4 groups. The constitution of theses groups was: A) normal control = 6 patients; B) Chagas' disease with positive serology only = 5 patients; C) Chagas' disease with cardiac disease = 6 patients, and D) Chagas' disease with digestive disease and vesical hyporeflexia = 11 patients. Urethral profilometry was performed through perfusion urethral catheter with a 6.5 ml/minute flow and a traction rate of 5 mm/minute. RESULTS: Means and standard deviations for urethral closure pressure before bethanechol chloride were respectively: group A = 67.3 ± 7.1; group B = 69.2 ± 7.4; group C = 95.8 ± 5.1; group D = 82.1 ± 8.4. After bethanechol chloride they were: group A = 66.0 ± 6.6; group B = 77.0 ± 7.6; group C = 98.3 ± 8.8; group D = 45.9 ± 6.2. The Kruskal Wallis statistical test did not show statistically significance difference between groups A, B, C. However, it was statistically significant between groups C and D with p = 0.003. Wilcoxon test showed p = 0.001, only for values in group D before and following bethanechol chloride. CONCLUSIONS: Chagas' disease in its intestinal form seems to alter urethral function as well. Parasympathetic stimulation decreased urethral pressure, indicating potential modulation by the parasympathetic system over the sympathetic system.

Objetivo: apresentar os aspectos clínicos, diagnósticos e terapêuticos de pacientes portadores de válvula da uretra anterior. Descrição: em dois neonatos, o diagnóstico presuntivo de patologia obstrutiva do trato urinário foi sugerido pela ultra-sonografia realizada no período pré-natal, confirmando-se o diagnóstico de válvula de uretra anterior pela avaliação pós-natal. Os pacientes foram submetidos a tratamento cirúrgico paliativo, com vesicostomia temporária e, posteriormente, definitivo, pela fulguração endoscópica das válvulas. Ambos evoluíram com função renal normal. Comentários: a válvula da uretra anterior é anomalia rara que deve ser considerada em meninos com quadro radiológico pré-natal sugestivo de obstrução infravesical, secundariamente à hipótese mais comum de válvula da uretra posterior. Ressaltamos a utilização da vesicostomia como derivação urinária temporária nestes casos, prevenindo potenciais complicações pela manipulação da uretra do recém-nascido.
Objective: to discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. Description: signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was performed in both patients. Later, the valves were fulgurated using an endoscopic procedure. During the follow-up period both patients presented normal renal function. Comments: anterior urethral valves are a rare form of urethral anomaly that must be ruled out in boys with pre-natal ultrasound indicating infravesical obstruction. Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra.
