ABSTRACT
Objetivos: determinar la asociación entre alteración orgánica y los hallazgos morfológicos patológicos en frotis de sangre periférica de pacientes con síndrome preeclampsia-eclampsia. Métodos: está enmarcada en un enfoque cuantitativo, descriptivo y transversal, que tiene como muestra a 54 pacientes, de una población de estudio de 137 pacientes que ingresaron con diagnóstico de Preeclampsia en el Hospital Materno Infantil German Urquidi, en periodo comprendido entre mayo y diciembre del 2016. Consistió en realizar una revisión documentada a través de lista de cotejo de las alteraciones clínica-laboratoriales de cada una de las pacientes; así como la visualización microscópica del extendido de frotis de sangre periférica en búsqueda de esquistocitos, equinocitos y agregados plaquetarios, realizado en un laboratorio autorizado por SEDES. Resultados: de 54 pacientes el 85% presento esquistocitos, equinocitos y agregados plaquetarios, considerándose como resultado positivo; el 15% restante no presentó ninguna de estas alteraciones considerándose como resultado negativo. Tomando estos resultados y comparando con las alteraciones clínica-laboratoriales en este grupo de estudio se pudo determinar que existe asociación entre frotis positivo y alteración orgánica; siendo la razón de probabilidad (OR) de 66; traducido en probabilidades es igual a 98.5% de riesgo de alteración orgánica con un frotis de sangre periférico positivo (Tabla 1). Conclusiones: la búsqueda de esquistocitos, equinocitos y agregados plaquetarios en frotis de sangre periferica es un método sencillo de realizar, económico y rápido; que muestra la probabilidad de desarrollar alguna alteración orgánica cuando el frotis de sangre periférica es positivo; anticipándose por lo tanto a la exacerbación de las manifestaciones clínicas y bioquímicas en pacientes con preeclampsia.
Objectives: to determine the association between organic alteration and pathological morphological findings in peripheral blood smears of patients with preeclampsia-eclampsia syndrome. Methods: It is framed in a quantitative, descriptive and transversal approach, which shows 54 patients from a study population of 137 patients admitted with diagnosis of preeclampsia at the Hospital Materno Infantil German Urquidi, between May and December Of 2016. It is consisted of a documented review through a checklist of the clinical-laboratory alterations of each one of the patients; as the microscopic visualization of the spread of peripheral blood smear in search of schistocytes, equinocytes and platelet aggregates, it was performed in a laboratory authorized by SEDES. Results: of 54 patients, 85% presented schistocytes, equinocytes and platelet aggregates, considered as a positive result; the remaining 15% did not present any of these alterations considering as a negative result. Taking these results and comparing with the clinical-laboratory alterations in this study group, it was possible to determine that there is an association between positive smear and organic alteration; The odds ratio (OR) being 66; Translated in probabilities is equal to 98.5% risk of organic alteration with a positive peripheral blood smear (Table 1). Conclusions: The search for schistocytes, equinocytes and platelet aggregates in smears of peripheral blood is a simple, economical and fast method to perform; which shows the probability of developing some organic alteration when the smear of peripheral blood is positive; thus anticipating the exacerbation of clinical and biochemical manifestations in patients with preeclampsia.

AIM:To observe the levels of monocyte-platelet aggregates (MPA) and markers of activated monocytes in patients with unstable angina pectoris (UAP) accepting Ginkgo biloba tablet treatments,and to explore its mechanisms for cardiovascular disease treatments.METHODS:The levels of MPA,CD11b,and MCP-1 were measured in 92 unstable angina pectoris (UAP) and 42 stable angina pectoris (SAP).The UAP patients were randomly assigned into routine treatment group (control group) and combined tablet treatment group (Ginkgo biloba group).The efficacy was assessed,and the levels of MPA,CD11b,and MCP-1 were measured after 28 days of treatment,respectively.RESULTS:The levels of MPA,CD11b,and MCP-1 in UAP group were higher than those in SAP group (P＜0.001).The levels of MPA and CD11b were positively correlated with MCP-1 level (P ＜ 0.01).The total rate of effective Ginkgo biloba tablet treatment was higher than that of non-Ginkgo biloba tablet treatment (P ＜ 0.05).After 28 days of treatments,the levels of MPA,CD11b,and MCP-1 in Ginkgo biloba group were significantly lower than those in control group (P ＜ 0.001).In total effective treatment group,the levels of MPA,CD11b,and MCP-1 were significantly lower after treatment than those before treatment (P ＜ 0.001),and the decreased rates of these markers after treatment were also much higher (P ＜ 0.01).CONCLUSION:There is an obvious efficacy of Ginkgo biloba tablet on unstable angina pectoris by down-regulating the levels of MPA,CD11b and MCP-1.
ABSTRACT
Pseudothrombocytopenia (PTP) is defi ned by falsely low platelet counts on automated analyzers caused by in vitro phenomena including large platelet aggregates in blood samples. Diagnosis and resolution of PTP is crucial as it can lead to unwarranted interventions. We discuss a case of PTP in a pre-surgical setting, which was resolved using 37°C incubation and Kanamycin.
ABSTRACT
Aim The effect and mechanism of human placental extract(HPE) on the lipoprotein-cholesterol metabolism, peroxidation and the function of platelet aggregation in hyperlipaemia rats were abserved.Methods Wistar rat with hyperlipaemia models were given each HPE 0.4 ml (100 g)-1?d-1 through lavage for 12 days.The serum levels of TG,TC,LDL-C,HDL-C and HDL2-C in its subgroup were measured.The activies of LPO and SOD in both blood and liver tissue were determined .The effect of HPE on lipidosis of liver were abserved by fat dyeing.The levels of 6-keto-PGF1?,TXB2 in plasma and maximum platelet aggregation rate were measured by ELASA. Result The levels of HDL-C and HDL2-C were increased (P
ABSTRACT
The Neurosensory retinal detachment contributes to the visual loss in the idiopathaic macular holes. Vitrectomy can be performed to reattach the retina by removing anterior-posterior and tangential traction between cortical vitreous and macular surface. Also bioadhesives, like autologous serum or platelets aggregates are used to flatten of surrounding rim detachment of macular holes. Among 22 eyes that underwent vitrectomy for the treatment of macular holes, anatomic success was achieved in 12 eyes (59.1%), and visual improvement in 10 eyes (45.5%). The time interval between diagnosis and operation was well-correlated to the functional success rate, while the type of surgical procedures was not. Postoperative complications included 2 cases of cataract, and 1 case of retinal detachment.
