ABSTRACT

RESUMEN Objetivos. Evaluar el efecto protector de Zea mays L. variedad morada (maíz morado) frente a la respuesta inflamatoria y daño osteoarticular en ratas con artritis experimental. Materiales y métodos. Se emplearon 65 ratas Holtzman, asignadas en siete grupos: G1 (n=5): control, G2 (n=10): pristane (PIA) + agua destilada, G3 (n=10): PIA + metotrexate 0,1 mg/kg, G4 (n=10): PIA + indometacina 0,6 mg/kg, G5 (n=10): PIA + Zea mays 100 mg/kg, G6 (n=10): PIA + Zea mays 1000 mg/kg y G7 (n=10): PIA + metotrexate 0,1 mg/kg + Zea mays 1000 mg/kg. Los tratamientos fueron administrados mediante cánula orogástrica diariamente durante 21 días; el pristane se administró vía subdérmica solo el día 1. Se registró el volumen de pata trasera con un pletismometro digital. El análisis radiológico de las patas se evaluó según los criterios de Clark modificado. Resultados. El porcentaje de inflamación al final del experimento fue: (G1) 1,50 ± 0,5, (G2) 13,73 ± 8,4; (G3) 14,76 ± 8,8; (G4) 14.22 ± 9,0; (G5) 10,81 ± 9.1; (G6) 5,31 ± 1.4; (G7) 6,38 ± 0,5. Los puntajes radiológicos de las áreas afectadas fueron: (G1) 0,6; (G2) 3,5; (G3) 0,6; (G4) 1,7; (G5) 1,9; (G6) 1,4; (G7) 1,0. Solo los grupos Zea mays L. 1000 mg/kg y metotrexate + Zea mays L. 1000 mg/kg mostraron una respuesta inflamatoria significativamente menor (p<0,05) y mostraron puntajes articulares significativamente bajos en relación a PIA. Conclusiones. El Zea mays L. (maíz morado) reduce el proceso inflamatorio y las modificaciones radiológicas de la artritis inducida por PIA en ratas de modo dosis dependiente.


ABSTRACT Objectives. To evaluate the protective effect of Zea mays L., purple variety (purple corn) against inflammatory response and osteoarticular damage in rats with experimental arthritis. Materials and Methods. Sixty-five Holtzman rats were used, assigned to seven groups: G1 (n=5): control; G2 (n=10): pristane (PIA) + distilled water; G3 (n=10): PIA + methotrexate 0.1 mg/kg; G4 (n=10): PIA + indomethacin 0.6 mg/kg; G5 (n=10): PIA + Zea mays 100 mg/kg; G6 (n=10): PIA + Zea mays 1000 mg/kg, and G7 (n=10): PIA + methotrexate 0.1 mg/kg + Zea mays 1000 mg/kg. Treatments were administered by orogastric cannula daily for 21 days; pristane was administered subdermal only on day 1. Volume of hind leg was recorded with a digital plethysmometer. The radiological analysis of the legs was evaluated according to the modified Clark criteria. Results. The percentage of inflammation at the end of the experiment was: (G1) 1.50 ± 0.5; (G2) 13.73 ± 8.4; (G3) 14.76 ± 8.8; (G4) 14.22 ± 9.0; (G5) 10.81 ± 9.1; (G6) 5.31 ± 1.4; (G7) 6.38 ± 0.5. The radiological scores of the affected areas were: (G1) 0.6; (G2) 3.5; (G3) 0.6; (G4) 1.7; (G5) 1.9; (G6) 1.4; (G7) 1.0. Only the groups Zea mays L. 1000 mg/kg and methotrexate + Zea mays L. 1000 mg/kg showed a significantly lower inflammatory response (p<0.05) and showed significantly lower joint scores in relation to PIA. Conclusions. Zea mays L. (purple corn) reduces the inflammatory process and radiological modifications of PIA-induced arthritis in rats in a dose-dependent manner.

ABSTRACT

Osteoarthritis is considered the most common joint disease in the world, especially among the aged population. But it may affect the kids as a secondary type when kids were administered some groups of drugs such as quinolones which cause cartilage deformations and predispose to secondary type of osteoarthritis. This study aims to investigate the protective effect of glucosamine and chondroitin alone and in combination in the treatment of arthritis in Juvenile Rats. This study was applied on 5 groups of juvenile wistar rats, which divided as: normal group, control group, the group of GA, group of CS, the group of combination between GA+CS. At the end of the study all of rats were killed, then measurement of maximum extension of the right knee were performed, also histological and functional analysis of the articular cartilage of the knee were performed. Control group showed the degenerative changes as compared to the normal group, which is improved into the groups of GA, CS, which distinguished from the combination group. This study shows that GA and CS have protective effect able to opposite the destructive effect of quinolone on immature cartilages

ABSTRACT

Com o objetivo de estimar a prevalência de sintomas articulares crônicos e seus determinantes, foi realizado um estudo transversal, com 2.953 adultos com 20 anos ou mais, residentes em Pelotas, Rio Grande do Sul, Brasil. Foram investigadas a presença de dor, edema ou rigidez articular, além de informações demográficas, sócio-econômicas e sobre problemas de saúde. A análise multivariável foi realizada pela regressão de Poisson. A prevalência geral de sintomas articulares crônicos foi de 36,5 por cento (42,4 por cento nas mulheres e 28,7 por cento nos homens). A presença da tríade - dor, edema e rigidez articulares - foi de 14,1 por cento e 5,5 por cento nas mulheres e homens, respectivamente. Sintomas articulares crônicos se mostraram linearmente associados ao aumento da idade (RP: 2,9; IC95 por cento: 2,4-3,5), do índice de massa corporal (RP: 1,6; IC95 por cento: 1,3-2,0) e à menor escolaridade (RP: 1,5; IC95 por cento: 1,3-1,8). Somente 6 por cento dos homens e 18 por cento das mulheres relataram diagnóstico médico de artrite. As prevalências gerais de limitações para atividades de vida diária e para atividades laborais, secundárias a sintomas articulares crônicos, foi de 15 por cento e 21 por cento, respectivamente. Os jovens e homens representam a maioria dos indivíduos com sintomas articulares crônicos subdiagnosticados.


With the objective of estimating the prevalence of chronic joint symptoms and their determinants, a cross-sectional study was conducted with 2,953 adults 20 years or older in Pelotas, Rio Grande do Sul State, Brazil. Pain, swelling, and stiffness in joints were investigated, plus demographic, socioeconomic, and health-related information. Multivariate analysis was performed with Poisson regression. Overall prevalence of chronic joint symptoms was 36.5 percent (42.4 percent in women and 28.7 percent in men). The threefold presence of pain, swelling, and stiffness in joints was 14.1 percent and 5.5 percent in women and men, respectively. Chronic joint symptoms showed a linear association with increasing age (PR: 2.9; 95 percentCI: 2.4-3.5), body mass index (PR: 1.6; 95 percentCI: 1.3-2.0), and less schooling (PR: 1.5; 95 percentCI: 1.3-1.8). Only 6 percent of men and 18 percent of women had a medical diagnosis of arthritis. Overall prevalence rates for limitations in activities of daily living and work secondary to chronic joint symptoms were 15 percent and 21 percent, respectively. Young people and men represent the majority of individuals with under-diagnosed chronic joint symptoms.

ABSTRACT

A CAE é provocada por um lentivírus. Os animais infectam-se, principalmente, quando mamam colostro e/ou leite contaminados. Neste trabalho, propôs-se um plano de controle da CAE, sem que se sacrificassem as mães contaminadas. Utilizaram-se 39 cabritas, nascidas de mães soropositivas para a CAE. Após o nascimento, as cabritas foram isoladas das mães e alimentadas com colostro de cabras soronegativas, tratado termicamente, e com leite de cabra pasteurizado, até os dois meses. Submeteram-se todas as cabritas ao teste sorológico, trimestralmente, do nascimento aos 12 meses; segregaram-se as soropositivas do rebanho. O grupo controle consistiu de 12 cabritos, nascidos de cabras soropositivas, os quais permaneceram com suas mães. O procedimento de diagnóstico foi o mesmo, mas não foram segregados os positivos. Ao final de 12 meses, 34 (87%) animais do grupo experimental permaneceram soronegativos, com limites de confiança de 76% a 98%; nos animais do grupo controle, a taxa de negatividade acumulada foi de 17%, com limites de confiança entre 0% e 38%. Com esses resultados, conclui-se que o plano proposto é viável para garantir o controle da enfermidade, em rebanhos contaminados, ou seja, a não-adoção do mesmo pode levar à contaminação dos animais nascidos de cabras infectadas.


CAE is caused by a lentivirus. The animals are mainly infected when taking contaminated colostrums and/ or milk. This study proposed a CAE control strategy without sacrificing contaminated mothers. Thirty-nine female kids, born to CAE seropositive mothers were isolated from their mothers at birth and fed heat-treated colostrum and pasteurized milk from seronegative goats up to two months of age. All kids were submitted to three-monthly serological tests from birth to 12 months; seropositives were segregated from the herd. The control group consisted of 12 kids born to seropositive mothers that remained with their mothers. Diagnosis was the same, but seropositive animals were not segregated. At the end of 12 months, 34 (87%) animals from the experimental group remained seronegative with 76% to 98% confidence limits; in control group animals, the accumulated negativity rate was 17%, with 0% and 38% confidence limits. These results show that the proposed plan is viable to assure disease control in contaminated herds and that without it contamination can pass to animals born to infected goats.

ABSTRACT

The concept that cancer, chronic inflammation and degenerative diseases of the central nervous system and other vital organs can be postponed or even prevented by certain food-derived substances is currently eliciting considerable interest. Finding pharmacologically safe food-derived agents which are able to interfere with tumour development, inflammation and neurodegeneration is the holy grail of medicine and is therefore of considerable clinical value. Kurkum or Curcumin [diferuloylmethane] is the biologically active component of the naturally occurring yellow pigment in Turmeric which is isolated from the rhizomes of the plant Curcuma longa. Turmeric is widely used in curries in East Indian and Middle Eastern cuisine. Curcumin has received a great deal of attention by numerous biomedical research teams since the 1980's due to its potent anti-cancer, antimetastatic and anti-inflammatory properties. There is also evidence that Curcumin may reverse neurodegeneration in Alzheimer's disease by breaking up amyloid plaques in the brains of Alzheimer's patients. More recent and highly controversial studies suggest that Curcumin may also correct the cystic fibrosis defect in mice. A better understanding of the biological function of Curcumin and structurally related compounds in each of these diseases will help development of clinically safe chemopreventive agents designed for the treatment of many clinical conditions including cancer, chronic inflammatory disease and neurodegeneration. In this review, the properties of Turmeric and its key ingredient Curcumin are discussed in the context of favourable actions against carcinogenesis and inflammation in an effort to highlight their nutritional benefits to Muslim readers of the journal

ABSTRACT

A febre reumática (FR) permanece um problema de Saúde Pública nos países subdesenvolvidos e mesmo nos desenvolvidos ela está ressurgindo. Portanto, a proposta deste estudo é delinear a epidemiologia dessa patologia em nossa cidade para que se possa desenvolver futuramente estratégias de prevençäo adequadas. Procedeu-se a análise retrospectiva de uma amostra de 267 crianças abaixo de 15 anos atendidas no Serviço de Reumatologia Pediátrica do Do Hospital Universitário Evangélico de Curitiba, no período de abril de 1986 a abril de 1997, dos quais 81 (30,3 por cento) apresentaram diagnóstico de FR e tiveram seus prontuários analisados detalhadamente, quanto aos aspectos clínicos, diagnósticos e terapêuticos. Na análise dos pacientes com FR, observou-se uma incidência significativamente maior nas crianças com idade entre 9 e 11 anos (53,1 por cento) (p<0,001), bem como a raça branca foi a prevalente (95,0 por cento) (p<0,001). Os meses de junho, julho e agosto constituem o período em que mais se giagnosticou a FR, sendo o mês de junho o de maior frequência (18,5 por cento) (p<0,005). Houve um pico de casos nos anos de 1988 e 1990 (13,6 por cento) em cada ano (p<0,005). A manifestaçäo clínica mais incidente foi a cardite com 54 casos (66,7 por cento) do total e associada a poliartrite também apresentou-se como a mais frequente com 49,4 por cento (p<0,001). Oexame laboratorial de VHS encontrou-se aumentado em um número significativo de pacientes, 71,8 por cento (28 de 39) (p<0,01). Atravé deste estudo vemos que a prevençäo pode ser feita com maior eficácia concentrando esforeços principalmente à prevençäo primária, alertando tanto profissionais da saúde, como as crianças de todas as idades durante o ano todo
