ABSTRACT
Resumen El desmembramiento del territorio de Quintana Roo, y su restablecimiento durante el gobierno cardenista establecieron las bases para que Payo Obispo iniciara su desarrollo como ciudad y capital del territorio; al mismo tiempo cambió su nombre por el de Chetumal. La destrucción de la ciudad ocasionada por el paso del huracán Janet, dio la oportunidad para reconstruir la ciudad y establecer las instituciones de salud actuales. En esta segunda parte, expondremos las contribuciones de la medicina militar a la capital de Quintana Roo en la segunda mitad del siglo XX y principios del siglo XXI.
Abstract The partition of the Territory of Quintana Roo, and its reestablishment during the government of the president Cardenas established the bases for Payo Obispo`s city to begin its development as a capital of the territory; at the same time it was renaimed as Chetumal. The destruction of the city caused by the passage of Hurricane Janet, gave the opportunity to rebuild the city and establish the current health institutions. In this second part, we will expose the contributions of military medicine to the capital of Quintana Roo, in the second half of the 20th century and the beginning of the 21st century.
ABSTRACT
Resumen La ciudad de Payo Obispo (hoy Chetumal) fue fundada en 1898, como punto estratégico militar y político para limitar el tráfico de armas y el comercio ilegal en la frontera con Belice. Las condiciones insalubres y sus limitadas vías de comunicación favorecieron la aparición de problemas serios de salud pública, como los brotes de enfermedades tropicales. En este trabajo abordaremos la participación de los médicos militares que se establecieron en Payo Obispo, durante la primera mitad del siglo XX, y cuyas contribuciones sentaron las bases del actual sistema de salud del estado de Quintana Roo.
Abstract The city of Payo Obispo (currently called Chetumal) was founded in 1898 as a strategic military and political point to limit arms trafficking and illegal trade on the border with Belize. The unhealthy conditions and limited communication routes favored the appearance of serious public health problems, such as outbreaks of tropical diseases. In this paper we will address the participation of the military doctors who settled in Payo Obispo, during the first half of the 20th century, and whose contributions laid the foundations of the current health system in Quintana Roo.
ABSTRACT
In order to determine temporal and spatial distribution patterns of Callinectes sapidus, samplings were carried out during the cold-front (January-February), dry (May-June) and rainy (August-September, 2002) climatic seasons, in 30 sampling stations of Chetumal Bay, grouped in sectors A (14 stations), B (eight stations) and C (eight stations). In each sampling station crabs were collected from two transects parallel to the coast, each with three traps, separated by 30 m. Sediments were calcareous coarse and medium sand, white or lightly gray. A total of 1 031 specimens were collected. CPEU (Capture Per Effort Unit) differed spatially and temporally. Highest CPEU was found in sector C with 1.3 ind.trap(-1), and in the rainy season with 1.1 ind.trap(-1). Population was predominantly composed of male individuals. The male:female ratio was 15:1. Males and adults (group II) CPEU was significant different between sectors and climatic seasons. Both males and adults (group II) had a greater CPEU in sector C (1.2 ind.trap-) and in the rainy season (1.1 ind.trap(-1)). Abundance of female and juvenile individuals (group I) was low during the sampling period whereas group 0 juvenile individuals were not found. A greater relative frequency between sectors and climatic seasons were observed in 130-139 mm and 140-149 mm size interval (CW). C. sapidus occurred on sandy sediments in Chetumal Bay. Pearson product moment correlations exhibited significant relationships between CPEU and temperature, salinity and dissolved oxygen. In Chetumal Bay, the spatial and temporal distribution of C. sapidus can be related to salinity, temperature, habitat quality, food availability, recruitment and reproduction events of individuals.
