Characterization and seminal cryopreservation of three species of birds of prey.

Background: Assisted reproduction techniques in birds have contributed to many species' conservation and sustainable use. One of these techniques is semen cryopreservation, which is possible following the discovery of suitable cryoprotectants.

Aims: This study aimed to characterize the fresh and post-thaw ejaculates of different species of birds of prey.

PP078. Total antioxidant capacity in patients with pregnancy induced hypertension: Its relation to maternal and/or perinatal complications.

Introduction: Pregnancy-induced hypertension (PIH) is a major cause of maternal and perinatal mortality and morbidity, particularly in under-resourced countries, like Mexico. Studies on PIH have shown increased oxidative stress products such as malondialdehyde and decrease of total antioxidant capacity (TAC). In this research we measured one marker of oxidative stress (OS) the TAC in patients with PIH and we associated it with the development of maternal and/or fetal complications.

Male rat infertility induction/spermatozoa and epididymal plasma abnormalities after oral administration of Kalanchoe gastonis bonnieri natural juice.

Natural aqueous crude extracts (NACE) of several Crassulaceae family plants have been applied as a vaginal contraceptive by the populace. The aim of this work was to evaluate the inhibition of fertility in male Wistar rats and some physiological and biochemical changes in spermatozoa and epididymal plasma induced by NACE from Kalanchoe gastonis bonnieri (K. g.

[Trying vaginal delivery in 1000 patients with previous cesarean section in the Antiguo Hospital Civil de Guadalajara].

Because of the main justification for practicing a cesarean section is due to a previous cesarean and the rasing rates frequency of this operation, we concluded a descriptive and prospective investigation in order to analize the factibility and security of vaginal delivery after one cesarean section. We include 1000 patients with a past history of one previous cesarean section and with the following main characteristics: normal evaluation of the actual pregnancy and a gestational age of at least 36 weeks of pregnancy, no pelvis stenosis and a normal fetal status. The management were expectant and or with the use of oxitocin, prostaglandin PGEJ, uterionhibition and or amnioinfusion according to medical indication, 679 (67.

[Reduction of the number of cesarean sections from 28% to 13%: does it reduce or increase perinatal maternal mortality: the great doubt?].

According to the new trends related to decrease the cesarean section rates, we conducted our retrospective investigation in order to investigate if the decrease of the cesarean section from 28 to 13%, affect the perinatal mortality (before labor and during labor) and maternal mortality. The years included in this paper were 1990 and 1995. We justified our investigation because some professional in health, believe that the decrease of the cesarean section produce an increase of the maternal and perinatal mortality.
