RESUMENLa información básica sobre los perfiles hematológicos de los murciélagos es muy limitada y dispersa. Para este estudio, nos propusimos compilar la información disponible al respecto con el fin de establecer patrones derivados de su análisis. En los murciélagos, el valor medio de hematocrito se encuentra alrededor del 56%, el recuento de glóbulos rojos promedio es de 10 106/µl, el de glóbulos blancos 5,300 cel/µl, la concentración de hemoglobina 17 g/dL y el recuento diferencial de glóbulos blancos es 42% de neutrófilos, 54% de linfocitos, 2% de monocitos, 1% de eosinófilos y 1% de basófilos. La información existente corresponde a sólo 7.3% de las especies conocidas actualmente incluidas en el orden Chiroptera (1,116). En la literatura disponible no parece establecerse una distinción sexual de perfiles hematológicos. En la distribución de la fórmula leucocitaria de la mayoría de las especies estudiadas se observa un predominio linfocitario que recibe el nombre de “fórmula invertida” o “desviación a la derecha”, pese a que en algunas especies se puede observar una fórmula leucocitaria con predominio de neutrófilos, lo que se denomina en hematología humana “fórmula hacia la izquierda” o “fórmula tipo neutrófilo”.  La variación en la fórmula leucocitaria de mamíferos se puede deber a factores funcionales y/o genéticos. La información disponible para 81 especies resulta escasa para un grupo tan diverso como el de los murciélagos, por lo cual no es posible establecer patrones claros e inequívocos. Investigaciones profundas y detalladas son primordiales para ello, a fin de identificar los factores asociados a la variación en los parámetros hematológicos.Palabras clave: Chiroptera, eritrocito, hematocrito, hematología, hemoglobina.ABSTRACTGeneral information on hematological profiles of bats is very limited and scattered. For this study, our goal was to compile the available information on this topic to determine the pattern, if any, derived from its analysis. In bats, the average hematocrit (Hct) level is around 56%, the average red blood cell count (rbc; erythrocytes) is 10 106/µl, the average total white blood cell count (twbc; leukocytes) is 5,300 cel/µl, the hemoglobin is around 17 g/dL, and the averages of differential white blood cell counts (dwbc) are 42% of neutrophils, 54% of lymphocytes, 2% of monocytes, 1% of eosinophils, and 1% of basophils. The available information for bats as a group corresponds only to 7.3% of the currently valid species (1,116). In the available literature, it does not seem to exist a sexual differentiation between hematological profiles. In the distribution of the leucocitarian formula of most species of bats included here it seems to exist an important proportion of lymphocytes, know as “inverted formula” or “right bias”, although in some species it seems to be an important proportion of neutrophils, known as “left bias” or “neutrophil-type formula”. In mammals, the variation in this leucocitarian formula depends on functional or genetic factors. The available information for only 81 species of bats is insufficient for a highly diverse group, thus it is not possible to establish currently unequivocal patterns. Further detailed and systematic research is of paramount importance, to finally determine accurate causes of these values and the maintanance of these trends. Key words: Chiroptera, erythrocyte, hematocrite, hematology, hemoglobin.

Introduction. In general, chronic wounds are colonized by bacteria; however, when microorganisms start to multiply at higher levels, wounds can become infected, causing prolongation of the inflammatory phase and retardation of collagen synthesis and epithelialization. Objective. The objective of this study was to evaluate the presence of infection in venous ulcers after 12 weeks of treatment with autologous platelet-rich plasma (PRP) and determine global white blood cell counts. Materials and Methods. This case series study involved a sequential sample of 17 patients with venous ulcers treated with PRP for 12 weeks. Descriptive and inferential statistical analysis was performed using the McNemar test and χ² test. Results. At baseline, 10 patients (58.8%) had wound infection. During the sixth week of treatment with PRP, only 3 patients (17.6%) continued to exhibit wound infection. After 12 weeks of PRP treatment, only 1 patient (5.9%) continued to exhibit wound infection. McNemar and χ² tests used to assess the presence of infection in the intervention group produced a P value of .0039 for a comparison of baseline and week 6 and a P value of .0078 for a comparison of baseline and week 12. These results demonstrated significant differences from baseline at both 6 weeks and 12 weeks of treatment, with greater significance at 12 weeks. There was no relationship between global white blood cell count and the presence of infection. Conclusion. After intervention with PRP, 94% of patients experienced improvement concerning the infection of ulcers.
