ABSTRACT
Background: Bitter leaf and palm oil combination in treating diarrhoea is common in Africa. The aim of this study is to determine the synergistic and antimicrobial potential of Vernonia amygdalina and Elaeis guineensis on bacteria isolates from diarrheic stool.Methodology: One hundred and fifty (150) diarrheic stool samples from the Diagnostic Laboratory in Rivers State University Teaching Hospital (RSUTH), Port Harcourt, were inoculated in Selenite F broth, MacConkey, Nutrient and Salmonella-Shigella agar plates using standard methods. Fresh and dry bitter leaf extracts were prepared by mashing, weighing and dissolving 100 grams(g) and 150 g concentrations of each in 100 milliliters(mls) of ethanol and sterile distilled water respectively. Undiluted mixture of bitter leaf and palm oil were prepared by mixing 2 mls of each in a sterile beaker. Zero-point one milliliter (0.1ml) of each undiluted extract, their mixture, ethanol and palm oil were separately dispensed into appropriately labeled wells using sterile pipette for sensitivity test on the isolated bacteria. The pH, temperatures and the phytochemical contents of the bitter extracts and palm oil were determined using pH meter, thermometer and spectrophotometric method.Results: Escherichia coli, Staphylococcus aureus and Salmonella sp. were isolated. The pH and temperature of bitter leaf extract and palm oil were 7.2 and 26?C and 6.7 and 26?C respectively while the pH and temperature for bitter leaf and the palm oil mixture was 6.9 and 26?C. The bitter leaf and palm oil extracts, their combination, ethanol and distilled water used on the isolates as antibiotics did not show any sensitivity. The phytochemicals identified in the bitter leaf were saponins, alkaloids and tannins while carotene was detected in the palm oil.Conclusion: It can be concluded that the bitter leaf extract, palm oil and their combination did not inhibit the growth of bacteria as a result of lack of bioactive components from the bitter leaf. The nature of the diluents used for the extraction may not have been the right one as it would have caused the low concentration, dilution and disfiguring of the molecules of the bioactive compounds that prevented the proper reaction between the bacteria and the extracts used.
ABSTRACT
Leprosy/Hansen's Disease (HD) is associated with impairments and disabilities leading to stigma attached to the disease. Our study looks at the clinical spectrum and factors associated with disabilities over a 10 year period. It was a cross sectional retrospective analysis and included 240 patients which were followed in Christian Medical College and Hospital, Ludhiana, a Tertiary Care Hospital in North India. Objective of the study was to assess the pattern, prevalence and risk factors of disabilities in leprosy patients. The findings shows that the overall prevalence of disabilities was 57.9% (n=139) and was more common in males (73.4%). Patients, residents of Punjab had the maximum prevalence of disabilities (37.4%) followed by Bihar (27.3%). The commonest visible disability was madarosis (19.6%) followed by claw hand (12.1%). The maximum prevalence of clawing was noted in patients with BT-HD (31%) followed by TT-HD (27.6%). WHO Grade 1 disability was 24.5% while 60.4% had WHO Grade 2 disability. On multivariate analysis, positive skin smears and presence of lepra reaction at the time of diagnosis were found to be the risk factors associated with disabilities in leprosy. While the magnitude of disabilities in a referral tertiary care settings will not reflect true extent of problem in the community, information is relevant for improving the preventive and management strategies. Even in the post elimination era of leprosy, significant number and types of disabilities still persist. Like the tip of an iceberg, these findings imply that a more vigorous approach towards early and adequate treatment of complications like reactions is the need of the hour. Community based intervention studies in partnership with tertiary care hospitals may be useful in taking appropriate public health measures.
ABSTRACT
Tenderness and marbling are polygenic traits used as indicators of good meat quality. Among different genes related to meat quality, µ-calpaine (CAPN1) and thyroglobulin (TG5) have been specifically linked to tenderness and marbling, respectively. Objectives: to estimate the allelic and genotypic frequencies of markers in CAPN1 and TG5 genes, and relate their presence to beef carcass quality. Methods: CAPN1 and TG5 polymorphisms were identified by PCR-ACRS and PCR-RFLP, respectively, validating their putative effects on beef carcass using real time ultrasound in Charolais candidate sires (n=80). Results: computed genotypic frequencies in CAP4751 and TG5 showed Hardy-Weinberg equilibrium, while CAP316 expressed deviation from equilibrium. Association analysis indicated a significant effect of CAP4751 on rib eye area (REA) (p<0.05) and intramuscular fat (IMF) (p<0.10), while TG5 showed a significant trend on yield grade (YG). Conclusions: these results support the use of these markers for assessing traits related to meat quality, and warrant further studies to validate their use in cattle herds for breeding purposes.
La terneza y el marmoreo son características poligénicas e indicadoras de calidad en la carne bovina. Uno de los genes relacionados con la terneza en la carne es el gen de µ-calpaína (CAPN), en el cual se han identificado dos polimorfismos CAPN316 y CAPN4751 asociados significativamente a esta característica. En el gen de la Tiroglobulina (TG5) relacionado con el marmoleo, se ha identificado un polimorfismo en la posición -537del gen, asociado a la deposición de grasa intramuscular en bovinos. Objetivo: estimar las frecuencias genotípicas y alélicas de tres marcadores genéticos y su asocación con carcaterísticas de calidad de la carne bovina. Métodos: a partir de muestras de sangre de 80 toretes Charolais de 12 meses de edad mantenidos en pruebas de comportamiento, se caracterizaron polimorfismos en los marcadores CAPN316 y CAPN4751 identificados mediante el diseño de oligonucleótidos y la creación de sitios de restricción en la reacción en cadena de la polimerasa (PCR-ACRS) y de TG5 identifificado mediante PCR- RFLP, se utilizaron cebadores previamente reportados. Resultados: las frecuencias alélicas y genotípicas de los polimorfismo de CAPN4751 y TG5 mostraron estar en equilibrio genético; más no para CAPN316. Los análisis de asociación mostraron una diferencia significativa del marcador CAPN4751 sobre el área del músculo Longissimus dorsi (REA) (p<0.05) y grasa intramuscualr (IMF) (p<0.10); mientras que para TG5 hubo una tendencia significativa sobre el grado de rendimiento (YG). Conclusiones: dichos resultados sugieren el efecto potencial de estos marcadores comerciales sobre características de la carne, el estudio propone su uso sinérgico como complemento informativo de indicadores de la calidad en animales reproductores, pero resalta la necesidad de validación extensiva en poblaciones particulares para fomentar su uso en el mejoramiento de la ganadería para carne.
A maciez e o marmoreio são características poligênicas e indicadoras de qualidade da carne. Um dos genes relacionados à maciez da carne é o gene da -calpaína (CAPN1), no qual se tem identificados dois polimorfismos CAPN316 e CAPN4751 associados significativamente com esta característica. No gene da tiroglobulina (TG5) relacionado com o marmoreio, se tem identificado um polimorfismo na posição -537. Objetivo: estimar as frequências genotípicas e alélicas de três marcadores genéticos (SNP) e fazer a respectiva associação dos genótipos e alelos com os indicadores de qualidade da carne, obtendo um efeito significativo sobre algumas características de carcaça estimada pela ultrassonografia em tempo real em touros Charolês no noroeste do México. Métodos: foram identificados polimorfismos em três marcadores SNP a partir de 80 amostras de sangue de novilhos Charolês, sendo os SNP CAPN4751 e CAPN316 identificados após o desenho de oligonucleotídeos iniciadores e a criação de sítios de restrição na reação em cadeia da enzima polimerase (PCR-ACRS). O marcador TG5 foi identificado por PCR-RFLP com sequencias de oligonucleotídeos previamente reportadas. Resultados: Os polimorfismos CAPN4751 e TG5 mostraram estar em equilíbrio genético, mas o CAPN316 esta em desequilíbrio. A análise de associação demonstrou uma diferença estatística significativa para o marcador CAPN4751 em área do músculo Longissimus dorsi (REA) (p< 0.05) e gordura intramuscular (MI) (p<0.10), enquanto que para TG5 houve efeito significativo sobre rendimento (YG). Conclusões: Estes resultados sugerem o efeito potencial destes marcadores comerciais para melhorar as características de qualidade da carne. O estudo propõe a utilização das informações sinergicamente com os indicadores fenotípicos de qualidade da carne, mas salienta a necessidade da validação extensiva em populações específicas para incentivar a sua utilização no melhoramento de gado de corte.
ABSTRACT
Introducción: En las últimas dos décadas la reconstrucción mamaria inmediata ha pasado de ser un procedimiento rara vez sugerido y requerido por las pacientes a formar parte integral del manejo del cáncer de mama. El objetivo de la mastectomía con conservación de piel (SSM) es lograr un mejor resultado estético sin aumentar la tasa de recidivas ni el número de complicaciones esperadas. Objetivo: Evaluar la seguridad oncológica de la mastectomía con ahorro de piel para el tratamiento del carcinoma de mama, analizando la tasa de recurrencia local. Analizar las complicaciones de esta técnica quirúrgica comparada con la mastectomía convencional. Material y método: Se realizó un análisis retrospectivo de todas las pacientes operadas por cáncer de mama en los que se realizó una mastectomía utilizando una incisión con ahorro de piel desde marzo de 1998 a mayo de 2007 en el Servicio de Patología Mamaria del Hospital Británico de Buenos Aires. Sobre 4.121 registros de cáncer mamario se identificaron 137 pacientes. Resultados: Se estudiaron 137 pacientes cuya edad promedio fue 48,54 años con un seguimiento medio de 41,21 meses. Ninguna de las 37 pacientes con diagnóstico de carcinoma ductal in situ presentó recidivas locales ni enfermedad a distancia, con una sobrevida global promedio de 42,24 meses. La tasa de recidiva local global fue del 5,1 por ciento. El 7 por ciento de los carcinomas infiltrantes recayeron localmente, siendo el tiempo promedio de aparición de la recidiva 17,42 meses. Hubo menor número de complicaciones en el grupo de SSM comparado con las mastectomías convencionales, siendo significativa la diferencia para necrosis de colgajo de mastectomía y hematoma. Conclusiones: La SSM puede ser utilizada con criterio oncológico para el tratamiento de estadios iniciales del cáncer de mama. Tiene igual tasa de recidivas locales que las mastectomías convencionales pero con mejor resultado estético.

Increased dopamine catabolism may be associated with oxidative stress and neuronal cell death in Parkinson's disease. The present study was carried out to examine the effect of dopamine on the expression of heme oxygenase-1 and -2 (HO-1 and HO-2) in human neuroblastomas (SK-N-SH cell line) and the effects of selegiline and antioxidants on this expression. Cells were kept with close control of pH and were incubated with varying concentrations of dopamine (0.1-100 æM) for 24 h. HO-1 and HO-2 cDNA probes were prepared by reverse transcription-polymerase chain reaction amplification. The mRNA expression of HO-1 and HO-2 was measured by Northern blot analysis. The levels of HO-1 mRNA increased after dopamine treatment, in a dose-dependent manner, in all cell lines studied, whereas levels of the two HO-2 transcripts did not. The HO-1 and HO-2 protein expression was analyzed by Western blotting. HO-1 protein was undetectable in untreated SK-N-SH cells and increased after treatment with dopamine. In contrast, the HO-2 protein (36 kDa) was detected in untreated cells and the levels did not change as a result of treatment. alpha-Tocopherol (10-100 æM) and ascorbic acid (100 æM) did not attenuate the effects of dopamine. Selegiline (10 æM) produced significant increase (P < 0.01) in the induction of HO-1 by dopamine (more than six times the control values). The increased expression of HO-1 following dopamine treatment indicates that dopamine produces oxidative stress in this cell line.

In the Caribbean, remedies made from Chenopodium ambrosioides are commonly used internally to treat many medical conditions such as: asthma, dysentry, fatigue and worms. The bioactive component found in the oil of this plant is ascaridole, which causes severe gastro-intestinal discomfort if used excessively. Other hazardous plants include Datura stramonium and Abrus precatorius. It is, therefore, imperative for awareness programs to be set up to educate the population about the use of herbal remedies. Assistance from the Chemistry, Food and Drugs Division of the Ministry of Health in Trinidad and Tobago is needed to formulate guidelines for the proper use of of herbal remedies by patients. A database of tropical poisonous herbs should be made available to hospitals and other health facilities around the country. It is imperative for physicians to ask about their use of herbal supplements and remedies as they are ideally situated to give good counseling and to even help in integrating herbal modalities into conventional care

Although disease patterns vary from region to region; it must not assumed that malignant breast disease is uncommon in our region. A retrospective study of results of histological examination of breast lumps sent from the surgeons around the Freetown Area during the period October 1988 up to June 1990 showed that of 62 biopsies examined 14 were malignant
