In this prospective study of 50 patients, 36 of whom developed the adult respiratory distress syndrome (ARDS), early and intense complement activation was demonstrated. These patients were at risk of the ARDS because of multiple injuries, major abdominal surgery, acute pancreatitis, severe burns, or disseminated intravascular coagulation. Abnormal C3 consumption (as measured by the C3d/C3 ratio) and elevated plasma C5a-like activity (as measured by a leukocyte aggregation assay) were associated with, respectively, 84 and 86% of cases of ARDS. Both tests were more sensitive indicators of complement consumption than were assays of total hemolytic complement activity (CH50) or total C3. The C3d/C3 ratio showed a close, inverse correlation with CH50 in 47 healthy subjects, and was increased in 12 control patients after minor surgery. The C5a-like activity was found only in patients at risk of ARDS; it was highly associated with clinical conditions that predispose to the ARDS, but it cannot be considered as a real predictor of ARDS occurrence in these patients. Sequential samples from both sides of the pulmonary circulation showed initial pulmonary clearance followed by the release of C5a-like activity. No simultaneous changes in C3 levels were found, suggesting the possible presence of modulating factors. These observations suggest that other factors (e.g., hypoxia and metabolic cascades) may influence the development of ARDS. [less ▲]

We studied CSF CK and LDH isoenzyme activities in 27 patients with severe head injury and in 10 patients with chronic hydrocephalus not related to trauma. CSF enzymes showed an increased activity immediately after trauma, contrasting with the low values measured in the patients with hydrocephalus. In severe head injury, we found a correlation between enzyme release and brain dysfunction assessed according to two methods: the Glasgow coma scale (GCS), and the Liege coma scale (LCS) which uses elements of the GCS and the study of 5 brain stem reflexes. The correlation between enzyme activity and the Liege coma scores is better than that observed with the Glasgow coma scores. High enzyme activity is associated with a bad outcome at six months. It has a prognostic value on so far as it reflects the severity of traumatic structural brain damage. [less ▲]

Serial laboratory determinations are now routinely performed on patients admitted to intensive-care units. Adequate interpretation of such cumulative information for clinical decision-making purposes is a challenging problem. We describe a statistical method for predicting--sequentially as the data become available--the patient's outcome, death or survival. Thus, the method goes beyond previously reported techniques that base such prediction on only a single multivariate observation. The method has been applied to daily measurements of serum urea and lactate dehydrogenase, performed during one week on patients hospitalized in the coronary-care unit with acute myocardial infarction. Two baseline variables were also included in the dynamic risk index so derived: the age of the patient and the number of previous myocardial infarctions recorded on admission. We also discuss the problems of selecting the most-predictive laboratory tests and of determining for each test the amount of past data needed to achieve satisfactory prediction. We distinguish between global evaluation of the dynamic risk index obtained (in terms of specificity and sensitivity) and individual interpretation (in terms of posterior/prior probability ratio) of a given risk score for a particular patient. The approach described may contribute to more effective use of results of repeated laboratory tests on critically ill patients. [less ▲]

The distribution and concentrations of the basement membrane proteins laminin and type IV collagen were studied in isolated placental villi in normal pregnancy and in pre-eclampsia. In both cases these proteins could be localized by immunofluorescence in the trophoblast and capillary basement membranes, and occasionally also in the matrix surrounding the capillaries. The basement membrane proteins were quantified by solubilizing the villi with proteolytic enzymes and by subsequently measuring the concentrations of two resistant domains of these proteins (7-S collagen and the fragment PI, representing type IV collagen and laminin, respectively) with specific radioimmunoassays. The ratio type IV collagen:laminin was significantly higher in pre-eclamptic samples than in the controls, most probably reflecting a decrease in laminin concentration in the villi in pre-eclampsia. Such a change in the chemical composition of placental basement membranes could weaken the attachment of trophoblast cells to the underlying basement membrane and also modify the permeability and exchange properties of the villi.

DNA and protein synthesis have been studied in placental villi from normal and pathological cases by in vitro incorporation of tritiated thymidine or tritiated proline and subsequent counting or autoradiography. It appeared that cytotrophoblastic DNA synthesis continued until term and that it was particularly important in preeclampsia cases and in cases of villous immaturity (rhesus sensitization). Protein synthesis was also increased in preeclampsia and seemed to be due to a very active cytotrophoblastic metabolism. The most interesting finding was that in preeclampsia cases, especially when intrauterine growth retardation was superimposed, villous capillary endothelial cell proliferation was as prominent as in cases where villous maturation was not achieved. Such results are highly suggestive of an important compensatory proliferative mechanism in the placentae of preeclamptic women. [less ▲]

The distribution of fibronectin and the morphological differentiation of the genital ducts was studied in rat fetuses at ages from 15 to 21 days. Fibronectin was localized with the peroxidase-antiperoxidase and avidin-biotin method at the electron- and light-microscope level. In 15-day-old male and female fetuses, fibronectin was localized as a continuous lamella around the mesonephric duct and as a discontinuous lamella around the paramesonephric duct. During the differentiation of the female paramesonephric duct, the fibronectin layer became continuous and remained so after the age of 16 days. The fibronectin layer of the male mesonephric duct remained continuous at all ages. The accumulation of mesenchymal cells on the outer surface of the female mesonephric duct and the concomitant detachment of the fibronectin layer around the duct suggests that mesenchymal regulation plays a role in the regression of the mesonephric duct. In the regressing male paramesonephric duct fibronectin was simultaneously lost in the condensed periductal mesenchyme, the places of epithelio-mesenchymal contact, and the epithelial cytoplasmic protrusions towards the mesenchyme. Ultrastructurally, fibronectin was localized in the basal laminae, on the cell membrane in contact with the extracellular material, and on the surface of the fibrillar and flocculent extracellular material. In addition to auto- and heterophagy, epithelio-mesenchymal interactions seem to play an important role in the regression of the genital ducts, although in different ways in males and females. The present results give additional support to the theory of the possible migration of epithelial cells into the surrounding mesenchyme during the regression of the paramesonephric duct. [less ▲]

mmunofluorescent staining of frozen sections of rat bone marrow for collagen types I and III revealed the presence of a distinctive, collagen-producing cell type. Morphologically, these cells closely resembled reticular cells. They were large, with branching cytoplasm and were closely related to an extensive intercellular matrix of collagenous material that surrounded the hematopoietic cells of the marrow. Biochemical studies demonstrated synthesis of collagen types I and III, in a ratio of 4:1, by fresh rat bone marrow cells. [less ▲]

The dissociative electroionization of nitrous oxide into its four dissociation channels has been studied by a method using the kinetic energy and mass analysis. The formation of N2+, NO+, O+ and N+ are discussed essentially in terms of predissociation of the ground and excited N2O+ states between 15 and 40 eV. In most cases the predissociating states are also identified. The present results are compared with those in the literature. [less ▲]

The autocorrelation function C(t) associated with the vibrational motion in the A 2Pi u state of N2+ is calculated by three different methods. The classical method is based on classical trajectory calculations and provides good results except for secondary maxima appearing in the experimental autocorrelation function and resulting from interference effects. In the semiclassical method, the wavefunction is expanded in a basis of frozen gaussian functions. The secondary maxima are reproduced and the result is quite satisfactory. The superposition procedure consists in an expansion of the wavefunction in the eigenfunctions of the A state of N2+ and leads to a very simple formula for the autocorrelation function C(t). The secondary maxima are accounted for and the calculated function agrees very well with experimental results. [less ▲]

Several monobactams reacted with the serine dd-peptidases of Streptomyces R61 and Actinomadura R39 in a manner similar to that of bicyclic penicillins and cephalosporins. The dissociation constants of the Michaelis complexes formed between the R61 enzyme and sulfazecin (32 μM) and between the R39 peptidase and SQ 26324 (0.35 μM) had the lowest values ever observed with any β-lactam compound, suggesting an excellent fit of these two monobactams with the active sites of the respective enzymes. Azthreonam had a very poor inactivating potency, confirming its high selective reactivity towards the penicillin binding protein No. 3 of Escherichia coli. The Zn2+dd-peptidase (from Streptomyces albus G) had a high intrinsic resistance to β-lactam compounds whether they possessed a mono- or a bicyclic structure. [less ▲]

This review of 417 publications in the literature covers various aspects of the role of prostaglandins in human and animal reproductive physiology. The author points out that there are a variety of prostaglandins all belonging to a family of substances that derive from arachadonic acid. They are present in many human and animal tissues, are extremely labile and are involved in reproduction in the ovary in follicular development and release of the follicle, in the tube in migration of the gametes, and in the uterus in implantation and delivery. The author says that the role of prostaglandins is not an exclusive one but they are linked with the hypothalamo-pituitary hormones, as well as with progesterone and oestrogens. It may be possible that PGE helps to initiate follicular development by stimulating the appearance of LH and FSH receptors. PGE is also luteotrophic. Indomethacin which is a prostaglandin inhibitor however does not modify the ability of LH to stimulate luteinization and maturation of the oocyte. The author postulates on the origin and the identification of the luteolytic factor and gives schematic illustration of the arterio-venous blood supply between the uterus and the ovary which is so important for the good function of the prostaglandins. It is possible that PGF type prostaglandins which are vasoconstrictor may reduce the flow of blood around the ovary, perhaps even specifically to luteal tissue. He postulates that PGF2 alpha in its relationship to its receptors is necessary but insufficient to explain the full luteolytic effect. Turning to the semen he shows that the nature and concentration of prostaglandins in semen varies from one species to another. He thinks that there is a triple role for prostaglandins with semen, which is: a participation in the events of ejaculation, an effect on the female genital tract, and an effect on the mobility of spermatozoa. He speaks of the role of prostaglandins on the Fallopian tubes and believes that they do have an effect on determining the movement of the tubes but cannot explain exactly what. [less ▲]

Several types of active-site-directed inactivators (inhibitors) of the Zn2+-containing D-alanyl-D-alanine-cleaving carboxypeptidase were tested. (i) Among the heavy-atom-containing compounds examined, K2Pt(C2O4)2 inactivates the enzyme with a second-order rate constant of about 6 X 10(-2)M-1 X S-1 and has only one binding site located close to the Zn2+ cofactor within the enzyme active site. (ii) Several compounds possessing both a C-terminal carboxylate function and, at the other end of the molecule, a thiol, hydroxamate or carboxylate function were also examined. 3-Mercaptopropionate (racemic) and 3-mercaptoisobutyrate (L-isomer) inhibit the enzyme competitively with a Ki value of 5 X 10 X 10(-9)M. (iii) Classical beta-lactam compounds have a very weak inhibitory potency. Depending on the structure of the compounds, enzyme inhibition may be competitive (and binding occurs to the active site) or non-competitive (and binding causes disruption of the protein crystal lattice). (iv) 6-beta-Iodopenicillanate inactivates the enzyme in a complex way. At high beta-lactam concentrations, the pseudo-first-order rate constant of enzyme inactivation has a limit value of 7 X 10(-4)S-1 X 6-beta-Iodopenicillanate binds to the active site just in front of the Zn2+ cofactor and superimposes histidine-190, suggesting that permanent enzyme inactivation is by reaction with this latter residue.

Brain type creatine kinase isoenzyme (CK.-1) was measured in the ventricular cerebrospinal fluid in a series of 42 patients within 7 +/- 3,4 hours following severe head injury (GCS less than or equal to 7, LCS less than or equal to 12). The presence of the CK.-1 isoenzyme correlated with the degree of head injury as indexed by the Glasgow coma scale and the Liege coma scale. There was a significant logarithmic correlation between CK.-1 activity in the C.S.F. and the coma scores. However, the correlation with the Liege coma scale score (r = -0,84) is significantly better (Z = 1,97; p less than 0,05) than with the Glasgow coma scale score (r = -0,65). Thus, the Liege coma scale is a better index of neurological trauma. [less ▲]

Apolipoprotein A-I, the major protein in mammalian high-density lipoprotein, acts as a cofactor for lecithin-cholesterol acyltransferase during the formation of cholesterol ester and as such, is thought to promote cholesterol efflux from peripheral cells to the liver. In this paper, we report the partial purification of rat liver apolipoprotein A-I mRNA by a polysome immunoadsorption technique, and its cDNA cloning. Isolation of two overlapping cDNA clones enabled us to derive the whole rat apolipoprotein A-I cDNA coding sequence. Comparison of the deduced protein sequence with its human counterpart reveals a striking homology between the prepropeptide precursors. Both mature protein amino-terminal regions are very homologous, suggesting that this particular domain could be involved in lipid/protein binding or lecithin-cholesterol acyltransferase activation.

Two gold compounds with anti-inflammatory action are separately introduced into fluid negative liposomes : Aurol-sulfide (colloidal gold compound) into the aqueous phase of liposomes, Auranofin (soluble organic compound) into the lipidic phase. Their effects are analysed in synovial cells in culture. Aurol-sulfide, given alone, rapidly enters into the cells where it is found inside membrane limited inclusions. Under our experimental conditions, this agent is atoxic and has no effect on the cell cycle. When transported inside liposomes, Aurol-sulfide is found free, at least in part, in the cytoplasm and rapidly induces cell degeneration. Auranofin, given alone, is very cytotoxic under some experimental conditions. On the contrary, synovial cells are less sensitive to Auranofin whe encapsulated in liposomes. [less ▲]
