Testicular lactate dehydrogenase isozyme

Abstract 1. 1. Guinea pigs lactate dehydrogenase isozyme I B4 from heart, 5 A4 from skeletal muscle, and the two additional forms (X and X′) from mature testis have been isolated and partially purified. 2. 2. K m , optimum substrate concentration, inhibition by high concentration of substrate and the effect of certain inhibitors and pre-heating, showed values for X′ that were the average between those found for isozymes X and 5 (A4). 3. 3. Dissociation and recombination of polypeptides in vitro indicated that X is a homopolymer of chains (C) different from A and B, and that X′ is a hybrid of A and C units. 4. 4. Association of C and A polypeptides in vivo is possible in the precursor cells of the gametogenic line in which synthesis of the additional unit is started. In mature spermatozoa this hybridization does not occur, probably because the activity of genes controlling production of A and B chains is “turned of”.

Estado de salud bucodental de escolares residentes en localidades abastecidas con agua de consumo humano de muy alto y muy bajo contenido de fluoruros

Descrevem-se e analizam-se os resultados de uma pesquisa epidemiologica de corte transversal destinada a avaliar o estado de saude buco-dental de escolares de 6-7 e 12-13 anos, residentes em Sampacho e Portena, duas localidades da Provincia de Cordoba (Argentina), abastecidas com agua potavel contendo quantidade de F- muito diferentes. Em Sampacho o nivel de F- e de 9,05 mg/l enquanto que em Portena a concentracao e de 0,19mg/l. A proporcao de escolares (6-7 e 12-13 anos) que nao apresentaram carie foi significativamente maior em Sampacho do que em Portena, enquanto, que os indices ceo-d, ceo-s, CPO-D e CPO-S resultaram consideravelmente mais altos nesta ultima localidade. A severidade da doenca de carie nas criancas de 12-13 anos de Sampacho esteve compreendida entre as categorias baixa e moderada (CPO-D = 2,53), enquanto que em suas similares em Portena atingiu o grau de moderada e alta (CPO-D=4,41). Nao se registrou nenhum caso de fluorose dental em Portena enquanto que em Sampacho houve uma alta proporcao de criancas que apresentou fluoroses leve (6-7 anos) e leve ou intensa (12-13 anos). Os niveis salivares de calcio, fosfatos, tiocianato, proteinas totais e lg A secretora foram muito similares nos escolares de ambas localidades, e tambem entre criancas com diferentes tipos de carie e diferentes graus de gravidade de fluorose. Conclui-se ser necessaria a aplicacao de medidas sanitarias urgentes (preventivas ou curativas) para reduzir ou controlar as doencas de carie em Portena e a fluorose dental em Sampacho.Se describen y analizan los resultados de una investigacion epidemiologica de corte transversal destinada a evaluar el estado de salud bucodental en escolares de 6-7 y 12-13 anos residentes en Sampacho y Portena, dos localidades de la Provincia de Cordoba (Argentina), abastecidas con agua de bebida que poseen cantidades deF- muy diferentes. En Sampacho, el nivel de F- es de 9,05 mg/l, en tanto que en Portena la concentracion es de 0,19 mg/l. La proporcion de escolares (6-7 y 12-13 anos) que no tuvo experiencia de caries fue significativamente mayor en Sampacho que en Portena, mientras que los indices ceo-d, ceo-s, CPO-D y CPO-S resultaron considerablemente mas altos en esta ultima localidad. La severidad de la enfermedad de caries en los ninos de 12-13 anos de Sampacho estuvo comprendida entre baja y moderada (CPO-D= 2,53), en tanto que en sus similares de Portena alcanzo el grado de moderada a alta (CPO-D= 4,41). No se registro ningun caso de fluorosis dental en Portena, mientras que en Sampacho hubo una alta proporcion de ninos que presento fluorosis leve (6-7 anos) y leve o intensa (12-13 anos). Los niveles salivales de calcio, fosfatos, tiocianato, proteinas totales e Ig A secretoria fueron muy similares en los escolares de ambas localidades, y tambien entre ninos con diferente experiencia de caries y distintos grados de fluorosis dental. Se concluye que son necesarias urgentes medidas sanitarias (preventivas y/o curativas) para reducir o controlar la enfermedad de caries en Portena y la fluorosis dental en Sampacho.

Distribución de la caries dental en niños preescolares en una región urbana, Argentina, 1992

An investigation undertaken into a sample of 1,115 five-year old children attending kindergartens in the city of Córdoba (Argentina) is described. The investigation aimed at establishing the prevalence and distribution of dental caries by socioeconomic level. Research showed that the prevalence of caries had decreased 55.0% in relation to the 1973 figure, while the proportion of children with healthy teeth was 26.7% greater. The frequency and seriousness of the caries increased as the childs social position declined. At the highest socioeconomic level NES I = entrepreneurial and managerial bourgeoisie), the rates of caries were significantly lower than those at the lowest socioeconomic level (NES III = typical proletariat, nontypical proletariat and sub-proletariat) presenting dmf-t of 0.8 and 2.7, and dmf-s of 0.9 and 4.9, respectively. In NES III, the dmf-t main components were decayed and missing teeth, while in NES I filled teeth were the main components. The proportion of children with no experience of caries was 63.1% in NES I and 11.5% in NES III. Inversly, the rate dental health was higher in NES I (8.8) than in NES III (5.1). The cost per child required for the restorative treatment in approximately two and a half times greater in NES III than in NES I. Considering the sample as a whole the expenditure required for NES III would be more than ten times higher than that required for NES I.(ABSTRACT TRUNCATED AT 250 WORDS)An investigation undertaken into a sample of 1,115 five-year old children attending kindergartens in the city of Cordoba (Argentina) es described.

Evaluación del estado de salud bucodental en preescolares: estudio epidemiológico longitudinal (1993-1994), Córdoba, Argentina

A one-year longitudinal survey was carried out on a sample of the Cordoba City 4-year old kindergarten population (n = 820); so as to determine the role of several variables upon the incidence of caries. The dmf-t, dmf-s, oral hygiene and oral health indexes as well as incidence rates and caries relative risks of caries were inversely related to the socioeconomic level (SEL) of the children involved. Thus in the SEL III (typical proletariat, non-typical proletariat and sub-proletariat) children, the relative risk of caries was almost five times higher (RR = 4.9) than in the SEL I (entrepreneureal and managerial bourgeoisie) children. In SEL I, almost all new lesions occurred on smooth surfaces (61.2%), while in SEL III the molar occlusal faces were mainly affected (66.3%). Daily sugar intake was higher in SEL III children but experience of caries showed poor correlation to the amount (r = 0.40) and frequency (r = 0.52) of carbohydrate intake. No significant interlevel differences were observed in the biochemical salivary parameters analyzed. Assisted toothbrushing and fluoride topications strongly lowered the incidence of caries among SEL III children, also making the corresponding rates fall almost to SEL I values (0.31, 0.23 and 0.22 vs. 0.21). In conclusion, SEL III children should be treated prophylactically with effective preventive measures, because of their susceptibility to caries. Such preventive measures include assisted toothbrushing and fluoride topications.Se realizo un estudio longitudinal de un ano de duracion en una muestra (n = 820) de la poblacion preescolar de 4 anos de la Ciudad de Cordoba, Argentina, para establecer la participacion de diversas variables en la incidencia de caries. Los indices ceo-d, ceo-s, de higiene oral y de salud bucodental, como tambien las tasas de incidencia y los riesgos relativos de caries estuvieron inversamente relacionados con el Nivel Economicosocial (NES) de los ninos. En los preescolares del NES III (proletariado tipico, proletariado no tipico y subproletariado), el riesgo relativo de experimentar caries fue casi cinco veces mayor (RR = 4,9) que en el NES I (burguesias empresarial y gerencial). En el NES I, la mayoria de las nuevas lesiones se localizaron en las superficies lisas (61,2%), mientras que en el NES III afectaron predominantemente las superficies oclusales de los molares (66,3%). El consumo diario de azucares fue mayor en los ninos del NES III, pero la experiencia de caries se correlaciono debilmente con la cantidad o frecuencia de ingesta de estos carbohidratos (r = 0,40 y 0,52, respectivamente). No se registraron diferencias significativas interniveles en los parametros bioquimicos salivales analizados. El cepillado dental asistido y las aplicaciones topicas fluoruradas disminuyeron fuertemente la incidencia de caries en los ninos del NES III, reduciendo las correspondientes tasas a valores muy proximos a los del NES I (0,31, 0,23 y 0,22 vs. 0,21). Se concluye que los ninos del NES III, por su susceptibilidad a la caries, deberian ser asistidos precozmente con medidas preventivas eficaces, como lo son el cepillado dental asistido y las aplicaciones topicas fluoruradas.

Nivel de información y conducta farmacoterapéutica de los odontólogos, 1990

Descrevem-se os resultados de pesquisa destinada a avaliar conhecimentos farmacologicos, conducta de prescricao e propostas para melhorar o emprego de medicamentos em 285 odontologos da Cidade de Cordoba (Cordoba, Argentina). O estudo mostrou que 58,3% dos pesquisados obtem informacao em farmacologia e terapeutica principalmente atraves do material que provem dos laboratorios farmacoquimicos. Paralelamente, por volta de um terco dos pesquisados respondeu incorretamente ou nao respondeu perguntas ligadas com a farmacoterapeutica dos antimicrobianos e analgesicos antiinflamatorios de sua prescricao preferida. Embora 63,5% dos odontologos dissessem levar em consideracao a lista de medicamentos essenciais proposto para o sistema da seguranca social, muitas das drogas indicadas como de preferencia nao estao incluidas na mesma. Para antimicrobianos e analgesicos anti-inflamatorios as marcas indicadas com maior frequencia foram as de maior valor economico, se bem que 66,5% dos indagados afirmaram orientar a prescricao para os produtos de menor custo. A pesquisa revelou que cinco empresas farmacoquimicas concentram a provisao de antimicrobianos e analgesicos anti-inflamatorios prescritos da preferencia respectivamente de 83,7% e 82,4% dos odontologos consultados.Results of an investigation carried out into a population of 285 dentists in Cordoba City (Cordoba, Argentine) with a view to evaluating their pharmacological knowledge, prescriptive behaviour and proposals for the improvement of drug usage, are described. This study showed that 58.3% of the dentists surveyed get most of their pharmacological and therapeutic information through published material issued by pharmacochemical labs. At the same time, about one-third of the individuals surveyed either did not answer or gave incorrect answers to questions related to the pharmacotherapeutic effects the antimicrobial or anti-inflammatory analgesics of their preference. Although 63.5% of the dentists said that they had taken the essential drug model reference list issued by the social security system into account, many of the drugs selected as preferences were not to be found on it. Regarding anti-microbial or anti-inflammatory analgesic drugs, the brands most frequently prescribed were the more expensive ones, strong 66.5% of the dentists surveyed stated the contrary. Finally, this investigation revealed that five manufacturers together held a concentration of the anti-microbial and anti-inflammatory analgesics prescribed by 83.7% and 82.4% of the dentists consulted respectively.

Prevalencia de la caries dental en escolares de nivel primario de una región metropolitana de la Provincia de Córdoba, Argentina

The results of a dental health epidemiologic study in primary school-children (aged 6-12) attending both public (municipal and provincial) and private schools in the city of Cordoba are described. The incidence of deciduous teeth caries was from moderate to high among the 6-year-old school-children from municipal schools but it was low in the provincial and private schools (dmf-t = 4.44, 2.31 and 1.27 respectively). Among both provincial and municipal school-children the most significant component corresponded to teeth with caries and diagnosed extraction, whereas in private school-children it corresponded to filled teeth. The absence of active caries in children was 13.6% in municipal schools, 52.2% in provincial schools and 76.9% in private schools. In 12-year-old school-children, the prevalence of caries in permanent teeth was at the same low level in all schools with a DMF-T ranging from 1.85 (municipal) to 2.59 (private). In general, the need for dental treatment was considerable in all schools. It is concluded that the dental health levels achieved by municipal and provincial schools at the age of 12 must be attributed mainly to preventive measures; should children be assisted eralier, the results would be enhanced.The results of a dental health epidemiologic study in primary school-children (aged 6-12) attending both public (municipal and provincial) and private schools in the city of Cordoba are described.

En los ninos de 6 anos de escuelas municipales, la prevalencia de caries en elementos temporarios fue de moderada a alta, resultando baja para los escolares provinciales y privados (ceo-d = 4,44 , 2,31 y 1,27, respectivamente). Tanto en escolares municipales como provinciales, los componentes de mayor peso en el ceo-d fueron dientes cariados y con extraccion indicada, en tanto que en los privados correspondio a dientes obturados. La proporcion de ninos sin caries activa fue de 13,6% en las escuelas municipales, 52,2% en las provinciales y 76,9% en las privadas. En los escolares de 12 anos, la prevalencia de caries en denticion permanente resulto baja y comparable en los tres grupos de escuelas, registrandose un indice CPO-D que oscilo entre 1,85 (municipales) y 2,59 (privados). Para ambas edades, las necesidades de tratamiento odontologico fueron elevadas en las tres poblaciones escolares. Se concluye que los niveles de salud dental alcanzados por los escolares municipales y provinciales a la edad de 12 anos deben atribuirse principalmente al impacto producido por la aplicacion de medidas preventivas, cuya eficiencia podria ser aumentada si se orientaran a atender edades mas tempranas, sobre todo en las poblaciones de mayor riesgo.

Research showed that the prevalence of caries had decreased 55.0% in relation to the 1973 figure, while the proportion of children with healthy teeth was 26.7% greater. The frequency and seriousness of the caries increased as the childs social position declined. At the highest socioeconomic level NES I = entrepreneurial and managerial bourgeoisie), the rates of caries were significantly lower than those at the lowest socioeconomic level (NES III = typical proletariat, nontypical proletariat and sub-proletariat) presenting dmf-t of 0.8 and 2.7, and dmf-s of 0.9 and 4.9, respectively. In NES III, the dmf-t main components were decayed and missing teeth, while in NES I filled teeth were the main components. The proportion of children with no experience of caries was 63.1% in NES I and 11.5% in NES III. Inversly, the rate dental health was higher in NES I (8.8) than in NES III (5.1).
