ABSTRACT

RESUMEN Con el objetivo de caracterizar la morfometría e índices corporales de Eremophilus mutisii, se usaron treinta y tres peces (27 hembras y 6 machos) provenientes del río Bogotá, específicamente de la región de Suesca. La relación de aspecto de la aleta caudal se determinó mediante el software de análisis de imágenes ImageJ®. Se calculó el índice gonadosomático, hepatosomático y rendimiento en canal para cada pez. Para el análisis de los datos se usaron correlaciones, regresiones y técnicas de análisis multivariado (análisis discriminante canónico). Como resultado del estudio se encontró que el sexo no afecta la forma del cuerpo de los peces. La relación entre la longitud y el peso se ajustó para cada sexo. La relación de aspecto de la aleta caudal presentó un promedio de 1,57 lo que sugiere que la especie presenta hábito sedentario o de natación lenta. El índice gonadosomático de las hembras en maduración (media: 14,43%, rango: 8,84% a 23,22%) aumentó en función del peso corporal y fue mayor que el de los machos (media: 5,32%, rango: 2,31% a 8,29%). Por lo tanto, el rendimiento de la carcasa fue menor en las hembras en maduración. La media del índice hepatosomático para hembras fue 0,86% (rango: 0,43% a 1,88%) y para machos fue 0,63% (rango: 0,39% a 1,09%). En conclusión, Eremophilus mutisii es una especie sedentaria y las hembras se caracterizarán por presentar mayor índice gonadosomático y menor rendimiento en carcasa que los machos.


ABSTRACT With the aim of characterizing the morphometry and body indexes of Eremophilus mutisii, thirty-three fishes (27 females and 6 males) coming from the Bogotá river, specifically of the Suesca region, were used. The aspect ratio of the caudal fin was determined with the aid of the image analysis software ImageJ®. Gonadosomatic and hepatosomatic indexes and carcass yield were determined for each fish. Correlation, regression and multivariate (canonical discriminant analysis) techniques were used for data analysis. Results indicated that sex does not affect the body shape of the fishes. The relationship between length and weight was fitted for each sex. The average aspect ratio of the caudal fin was 1.57, which suggests that the species has sedentary habits or slow swimming. The gonadosomatic index of the maturing females (mean: 14.43 %; range: 8.84 % to 23.22 %) increased as a function of body weight and was greater than in males (mean: 5.32 %; range: 2.31 % to 8.29 %). Therefore, the carcass yield was lower in maturing females than in males. The mean of the hepatosomatic index for females was 0.86 % (range: 0.43 % to 1.88 %) and for males was 0.63 % (range: 0.39 % to 1.09 %). As a conclusion, Eremophilus mutisii is a sedentary fish species, and females exhibit greater gonadosomatic index and lower carcass yield than males.

ABSTRACT

Von Hippel-Lindau disease is a dominant autosomal genetic condition with variable penetrance and expressivity. It is characterized by hemangioblastomas in multiple organs but mainly in the retina and cerebellum. There is a predisposition to carcinoma. We report a cesarean section in a 28-year-old woman with von Hippel-Lindau disease. She had no neurologic symptoms at the time of the operation but a history of ocular and cerebellar involvement and several procedures to remove cerebellar hemangioblastomas. Epidural anesthesia was chosen given that there was no nervous system involvement at the time of surgery.

ABSTRACT

La enfermedad de von Hippel Lindau es un transtornogenético autosómico dominante con penetranciavariable, caracterizado por hemangioblastomas multiorgánicosprincipalmente en la retina y cerebelo y con predisposicióna desarrollar carcinoma. Se comunica el casode una gestante a término de 28 años de edad, portadorade la enfermedad de von Hippel Lindau, sin clínicaneurológica en el momento de la cesárea, con historia deafectación ocular y cerebelosa, a quien se le habían extirpadohemangioblastomas cerebelosos en varias ocasiones.Se eligió anestesia epidural por no presentar afectacióndel sistema nervioso, en el momento de la cirugía(AU)
