RESUMO O desenvolvimento de projetos que contemplem o cultivo e beneficiamento de plantas medicinais, com qualidade, é urgente e necessário, especialmente quando se considera a expansão da oferta desses produtos para o Sistema Único de Saúde (SUS). Nesta pesquisa, foi avaliada a existência de iniciativas que produzem e disponibilizam plantas medicinais de interesse do SUS, em municípios que compõem a Bacia Hidrográfica do Rio das Velhas (BHRV), em Minas Gerais. Foram visitados 45 municípios da Bacia buscando informações sobre atividades já existentes de produção e uso coletivo de plantas medicinais. Os dados sobre plantas medicinais já existentes foram posteriormente confrontados com informações epidemiológicas, como as principais causas de internações hospitalares e cobertura de equipes da Estratégia da Saúde da Família (ESF). A pesquisa evidenciou a existência de atividades filantrópicas e comerciais, relativas à utilização coletiva de plantas medicinais, apenas em Belo Horizonte, Capim Branco, Curvelo, Lassance, Nova Lima e Sete Lagoas. Vinte e sete espécies, nativas e exóticas, presentes na RDC 10/2010 da Anvisa são produzidas nessas iniciativas, e elas ocorrem tanto de forma espontânea como por meio de cultivo. A correlação das principais causas de internação hospitalar com as espécies vegetais disponíveis revelou potenciais locais de aproveitamento das plantas, inclusive pela ESF. O desenvolvimento da cadeia produtiva, trabalhando desde o cultivo até a dispensação aos usuários do SUS, pode representar uma oportunidade de integração de diferentes atores e instituições da região, além de incrementar o desenvolvimento econômico-social e a preservação da biodiversidade local.

ABSTRACT The development of projects that include the cultivation and processing of medicinal plants with quality is urgent and necessary, especially when considering the offer increase of these products to the Unified Health System (SUS). In this study, we evaluated the potential of the Rio das Velhas" watershed region (BHRV) in producing and using medicinal plants. We visited 45 cities of the watershed, seeking information about existing production and collective use of medicinal plants. Afterwards, the data obtained in the fieldwork were confronted with epidemiological information, such as hospitalization rates and coverage of the Family Health Strategy. The research showed the existence of commercial and philanthropic activities in Belo Horizonte, Capim Branco, Curvelo, Lassance, Nova Lima and Sete Lagoas. Twenty-seven species, native and exotic ones, included in the 10/2010 Resolution edited by the Brazilian Health Surveillance Agency (Anvisa), are produced in these initiatives, and they occur both spontaneously and through cultivation. The correlation of the leading causes for hospitalization and the available plant species showed potential use of local plants, including by the Family Health Strategy. The development of the production chain, from the plants" cultivation to the medicines" dispensation for the SUS users, may represent an opportunity of integration of different actors and institutions in the region, besides increasing the economic and social development and contributing to the preservation of local biodiversity.

The progressive behavior of the blood pressure of term newborns during the first week of life was assessed by the simultaneous use of oscillometric and Doppler methods. A total of 174 term neonates born at the Municipal Hospital Odilon Behrens in Belo Horizonte, from March 1996 to February 1997, were prospectively assessed. The oscillometric and Doppler ultrasonic methods were simultaneously used for four consecutive recordings obtained at 12 ± 6, 24 ± 6 and 72 ± 24 h and on the 7th ± 1 day of life. The combined use of the two methods simplified the procedure, with automatic cuff inflation and deflation, and speed was properly controlled with an automatic pressure monitor. The procedure was performed using a Y-connection to the mercury sphygmomanometer, with blood pressure being recorded with an automatic device and systolic blood pressure being measured simultaneously by Doppler ultrasound. The newborns were awake, not crying and in the supine position. A statistically significant increase in systolic and diastolic blood pressure was observed between the first and second, and the third and fourth measurements by Doppler and oscillometric methods. No significant correlation between birth weight, length, ponderal index and blood pressure was observed. The technique used represents a simpler and more accurate procedure for blood pressure measurement.

The objective of the present study was to evaluate associations between fiber intake, colonic transit time and stool frequency. Thirty-eight patients aged 4 to 14 years were submitted to alimentary evaluation and to measurement of colonic transit time. The median fiber intake of the total sample was age + 10.3 g/day. Only 18.4% of the subjects presented a daily dietary fiber intake below the levels recommended by the American Health Foundation. In this group, the median left colonic transit time was shorter than in the group with higher dietary fiber intake (11 vs 17 h, P = 0.067). The correlation between stool frequency and colonic transit time was negative and weak for left colon (r = -0.3, P = 0.04), and negative and moderate for rectosigmoid and total colon (r = -0.5, P<0.001 and r = -0.5, P<0.001, respectively). The stool frequency was lower in the group with slow transit time (0.8 vs 2.3 per week, P = 0.014). In conclusion, most patients with chronic functional constipation had adequate dietary fiber intake. The negative correlation between stool frequency and colonic transit time increased progressively from proximal segments to distal segments of the colon. Patients with normal and prolonged colonic transit time differ in terms of stool frequency.

OBJETIVOS: A proposta deste trabalho é investigar o perfil socioeconômico, o motivo de estudar medicina, a opção por especialidade e residência médica e a preferência em trabalhar como profissional liberal ou assalariado entre os estudantes de medicina da Universidade Federal de Minas Gerais (UFMG). MÉTODO: Durante o ano de 1997, realizou-se estudo comparativo entre os estudantes de medicina da UFMG do 5º período, iniciando o ciclo clínico, e aqueles do internato, terminando o ciclo clínico. Como instrumento foi utilizado um questionário distribuído a todos alunos das duas turmas. RESULTADOS: Houve grande semelhança entre os estudantes de 5º período e os do internato. Em torno de 50% dos estudantes eram do sexo feminino, mais da metade procedeu da capital do Estado, em Belo Horizonte, nasceu em família pequena com menos de três filhos, foi aprovada no primeiro vestibular e o pai cursou escola superior. A renda familiar situou-se entre 10 e 50 salários em 2/3 dos casos. Estes dados são compatíveis com a origem de classe média alta, embora em aproximadamente 12% a renda familiar foi inferior a 10 salários. A grande maioria estudou medicina por vocação ou altruísmo (80%), raramente por questões de mercado (<5%). Houve grande preferência pela medicina como profissão liberal (98%), mas em torno de 80% aceitaria o emprego público como alternativa. Quase todos (98%) pretendiam fazer residência médica e se tornar especialistas, poucos (<20%) indicaram entre estas as especialidades de área geral, como clínica médica, gineco-obstetrícia, pediatria e cirurgia. CONCLUSÃO: O estudo mostrou perfil socioeconômico relativamente elevado do estudante de medicina da UFMG e preferência pela prática especializada da medicina.

OBJECTIVE: this study was made with the medical students of the "Universidade Federal de Minas Gerais" (UFMG), to get their social economic profile, and their reasons for studying medicine, choosing the specialty, doing medical residence, and showing preferences for being a liberal professional or a salaried employee. METHODS: In 1997, a study was made comparing UFMG's medical students beginning their clinical practice (5th semester) and those medical students during the internship in the last term of clinical practice. Both groups were given questionnaires for evaluation. RESULTS: The results were similar for both groups and showed that women constituted almost 50% of the students and about 50% of them were from Belo Horizonte, the State capital of Minas Gerais, Brazil, and from small families with less than three children, and whose parents held a college degree. These students passed the college entrance exams on their first try. Two thirds of their families had income of about 10 to 50 Brazilian minimum wages, and approximately 12% of the families had an income of less than 10 minimum wages. The majority of the students decided to study medicine for altruism or vocational reason; very few (<5%) chose to study medicine for financial reasons. Almost all students (98%) preferred a liberal medical practice; however 80% would accept civil-service employment as an alternative. Nearly all of them (98%) chose to do medical residence to specialize. Most students would prefer to be specialists and only less than 20% would prefer to do general practice in areas such as adult and pediatric clinic, gynecology-obstetric and general surgery. CONCLUSION:. This study shows that medical students from UFMG have an elite social economic profile and a preference for specialized medical practice.
