The aim of this study was to determine whether plasma pregnancy-associated glycoprotein-1 (PAG-1) concentrations in pregnancy are affected by persistent Neospora caninum infection in dairy cows. The data analyzed were derived from 22 multiparous cows: 16 N. caninum-seropositive and 6 N. caninum-seronegative animals (used as controls). Three of the 16 seropositive cows aborted during the study period and the corresponding data were analyzed separately. Pregnancy diagnoses were performed on day 40 post-insemination by transrectal ultrasound, and by palpation per rectum on days 90, 120, 150, 180 and 210. Blood samples were collected from each animal immediately before each pregnancy diagnosis, and then at parturition or at the time of abortion detection. Plasma was tested for antibodies against N. caninum and PAG-1 concentrations were determined by radioimmunoassay. In non-aborting animals, the effects of neosporosis (seropositive versus seronegative), N. caninum antibody levels, semen providing bull, sex of the newborn, and day of gestation on PAG-1 concentrations were evaluated by GLM repeated measures analysis of variance. The effect of the gestation period (first half versus second half) on the N. caninum antibody titer was established by the Student's t-test in seropositive cows. A significant positive effect of gestation day on PAG-1 concentrations was observed (d.f.=6; F=12.6; P<0.0001). For all cows, PAG-1 concentrations increased steadily during the course of gestation, with peak concentrations recorded at parturition. Neosporosis (P=0.493), N. caninum antibody levels (P=0.921), sex of the newborn (P=0.856) and semen providing bull (P=0.087) had no effect on plasma PAG-1 concentration. There was a significant 52% increase (P<0.0001) in N. caninum antibody titers during the second half of gestation compared to the first half. The fates of the three aborting cows were abortion on gestation day 215 in one, and fetus mummification diagnosed on gestation days 180 and 210, respectively, in the remaining two cows. A luteolytic dose of prostaglandin was applied 30 days after mummification diagnosis in these last two cows, and fetus expulsion was detected on days 215 and 250, respectively. Two of the aborted fetuses were submitted to laboratory analysis and the presence of N. caninum was confirmed by specific PCR. In the cows with a mummified fetus, PAG-1 concentrations were low or undetectable when the diagnosis was made. These findings suggest that N. caninum infection has no effect on placental function in chronically infected, cows not suffering abortion, while PAG-1 measurements in aborting animals provide a useful indication of feto-placental status.

This paper evaluates the profiles obtained for caprine pregnancy associated glycoprotein (cPAG) in pregnant multiparous and nulliparous goats using the heterologous-radioimmunoassay (htPAG-RIA) and the homologous-RIA (hmPAG-RIA) systems during the pregnancy and postpartum periods. The results show that the cPAG concentrations detected through the hmPAG-RIA procedure were lower than those found through the htPAG-RIA method. No statistical differences were observed due to the maternal reproductive status (nulliparous or multiparous goats) during pregnancy using either one of the methods. However, pregnant and cyclic goats were distinguished from each other by cPAG concentrations verified through the hmPAG-RIA procedure. The lower cPAG concentrations detected through this method suggest that this system is more specific than the htPAG-RIA procedure to measure cPAG during pregnancy and postpartum period in goats. The homologous system was also an efficient method to predict pregnancies of only 35 days in both nulliparous and multiparous goats. (C) 2001 Published by Elsevier Science B.V. [less ▲]

Using specific immunological (1) and enzymatic (2) methods, we have measured prokallikrein, total, high, and low molecular weight kininogens in 36 severely burned patients. At admission to the intensive care unit, all constituents were significantly decreased when compared to previously defined reference intervals. The values remained low during the three first days after burn. The changes affecting total and low molecular weight kininogens were significantly correlated (p less than 0.05) with the severity of the burn area. Prokallikrein and kininogens levels were also closely related to the concentrations of C3c and C4 complement factors. [less ▲]

Fourteen patients with normal preoperative renal function underwent aortocoronary bypass graft using cardiopulmonary bypass (CPB) with pulsatile (P;n = 7) or non pulsatile (NP;n = 7) perfusion. In the two groups prebypass values of plasma renin activity (PRA) and urine beta 2-microglobulin (beta 2-M) were within normal limits. PRA increased significantly during CPB and the first 6 h after CPB only in the non-pulsatile group. In both groups, the urine beta 2-M level increased significantly during and after CPB; however, there was no significant difference in urine beta 2-M levels between the two groups. Also, the amount of beta 2-M excreted in urines per unit of time increased significantly in both groups during and after CPB; there was no significant difference between the two groups. [less ▲]

Certaines tendinopathies présentent une évolution désespérément chronique malgré l’instauration d’un traitement conservateur bien conduit. Diverses études soulignent les propriétés réparatrices des plaquettes qui pourraient accélérer la cicatrisation de différents tissus. Le plasma riche en plaquettes (platelet-rich plasma ou PRP) représenterait une thérapeutique d’avenir. Les plaquettes libéraient, lors de leur dégranulation, divers facteurs de croissance. Ceux-ci favoriseraient la cicatrisation tendineuse. Actuellement, les effets du PRP restent toujours discutés voire controversés : les résultats cliniques sont parfois contradictoires même si son efficacité in vitro et sur animal apparait plus franche. Cette variabilité pourrait s’expliquer par l’absence de consensus relatif au mode de préparation du PRP, à la concentration plaquettaire, à la présence ou non de leucocytes, à la technique d’infiltration et au protocole post-infiltration.

Plasma enhanced chemical vapor deposition has been tested for the formation of hydrophobic perfluorinated coating on the surface of hydrophilic poly(2-hydroxyethyl methacrylate-co-methyl methacrylate) [poly(HEMA-co-MMA)] substrates, used for the fabrication of intraocular lenses (IOLs). The properties of the dry and hydrated surface modified by two plasma techniques, Radio-frequency (RF) and Microwave (MW), were investigated in parallel by contact angle measurements in the dry and hydrated state, X-ray photoelectron spectroscopy, and atomic force microscopy. The coating stability and hydrophobicity were challenged by swelling and sterilizing the samples in water. Investigation of the optical performances of the modified samples was performed by ultraviolet spectroscopy and diopter measurements. Since materials with biomedical application are considered, the performances of their surface in contact with lens epithelial cells were tested at in vitro conditions, and repulsion was not found to be enhanced upon modification. Generally, the results showed poor stability of the coating and bring in question its covalent grafting to the surface. [less ▲]

Gastrointestinal disorders in horses leading to endotoxic shock could have further consequences on other splanchnic organs such as the pancreas, as can be seen in humans suffering from septic shock. In this study, the range of enzymatically active trypsin (EAT) in healthy horses was established and is similar to the range observed in healthy humans. EAT values were determined in horses with acute abdominal crises on admission as well as during anaesthesia and in the postoperative phase. A significant increase in plasma EAT was found in 59% of the horses with surgical colic when compared to our established reference range. Significantly higher values were found in severe shock cases. When separated in groups according to the duration of colic before referral, significantly higher EAT values were observed in the non-survivor group compared to the survivor group of colics of short duration. EAT plasma values increased significantly during the postoperative phase, and were significantly higher in small intestine obstructions than in large bowel disorders. In human medicine, hypovolaemic or septic shock patients show an increase in pancreatic proteases. Splanchnic hypoperfusion during shock could lead to pancreatic damage resulting in trypsin liberation into the peritoneal space and an increase in plasma levels. Trypsin is able to activate inflammatory cascades and leucocytes and could play a role in multiple organ failure. Further studies are needed to evaluate the implications of changes in plasma trypsin in the disease process of equine acute abdomen and to demonstrate possible pancreatic damage. [less ▲]

The aim of this field study was to investigate the relationship of plasma urea nitrogen (PUN) with the pregnancy rate in lactating AwassixMerino ewes. One hundred and eighty-five AwassixMerino ewes were used in the present study. Ewes were fed a diet containing 17.4% crude protein and were milked twice a day by the milking machine. The ewes were synchronized for estrus by insertion of intravaginal sponges containing 30mg flurogestone acetate for 14 days. At the time of sponge removal each ewe was administered eCG (600IU). All ewes were inseminated twice with fresh semen into the external os of the cervix at 48 and 56h after sponge removal. The day of insemination was considered as Day 0 for calculating the gestational period. Blood samples were collected from each ewe at Days 0, 18 for measurement of PUN concentrations and at Day 22 after AI for measurement of pregnancy-associated glycoprotein (PAG) by radioimmunoassay (RIA). Thirty-eight ewes (20.5%) were confirmed pregnant by PAG-RIA test at Day 22 and by ultrasonography at Day 80. The mean (+/-S.D.) concentration of PUN in all ewes at Day 0 was 12.7+/-4.6mmol/L. There were non-significant differences in the level of PUN between pregnant and non-pregnant ewes at Days 0 (12.2+/-4.2mmol/L vs. 12.8+/-4.7mmol/L, respectively) and 18 (9.6+/-2.9mmol/L vs. 10.4+/-4.0mmol/L, respectively) after AI. Mean PUN concentrations decreased significantly from Day 0 to Day 18 after AI in both pregnant and non-pregnant ewes. By using logistic regression analysis, there was no effect of PUN concentrations on the probability of pregnancy occurrence in the studied ewes (odds ratio: 0.97; 95% confidence interval: 0.9-1.05; P=0.45). In conclusion, there was no evidence of a relationship between PUN concentration and pregnancy rate for lactating AwassixMerino ewes in the present study because of low pregnancy rate observed.

Plasma levels of vitamin E (Vit. E), total lipids (TL), Vit. E to TL ratio and myeloperoxidase (MPO) were studied in 20 patients undergoing lumbar spinal surgery and randomly allocated to two anesthetic groups: propofol (bolus dose + continuous infusion and thiopental/isoflurane. Peripheral blood samples were withdrawn prior to induction, each hour during anesthesia and 1 h after the end of surgery. Mean Vit. E and TL levels as well as mean Vit. E to TL ratios remained in the normal range over the entire period of study whatever the anesthetic regimen. MPO levels rose significantly in the post-operative period only, but without statistical difference between the two groups. Therefore, anesthesia with propofol or thiopental/isoflurane modifies neither total lipid concentrations nor plasma Vit. E, which is a potent endogenous inhibitor of lipid peroxidation bound to lipoproteins. The rise of plasma MPO suggests a moderate post-operative neutrophil activation which is not influenced by anesthetic techniques. [less ▲]

A case of solitary plasmacytoma of the thyroid is reported. A monoclonal component (IgG lambda) was identified in the serum of the patient and disappeared after total thyroidectomy and radiotherapy. The use of the immunoperoxidase technique on thyroid, bone marrow, and lymph node specimens allowed us to demonstrate the production of IgG lambda by the tumor, and to rule out the possibility of multiple myeloma. Previously reported cases are reviewed (15 cases). The diagnostic criteria, the association with thyroiditis, and the treatment of this rare disorder are discussed. [less ▲]

OBJECTIVE: To compare the sensitivity of cystatin C and creatinine in detecting decreased glomerular filtration rate. DESIGN: Prospective observational study. SETTING: Medical intensive care unit at a university hospital. PATIENTS AND PARTICIPANTS: Fourteen patients hospitalised in a medical intensive care unit. INTERVENTIONS: Cystatin C and creatinine plasmatic levels were measured in 40 blood samples taken with an interval of at least 24 h. MEASUREMENTS AND RESULTS: Glomerular filtration rate was estimated by creatinine clearance using 24-h urine collection and the classical Cockcroft-Gault equation. The ability of cystatin C to detect a glomerular filtration rate under 80 ml/min per 1.73 m(2) was significantly better than that of creatinine ( p<0.05). CONCLUSIONS: Cystatin C, a new plasmatic marker of renal function, could be used to detect renal failure in intensive care in the future. [less ▲]
