[more ▼] A split-dose regimen of whole-body irradiation (4 X 175 rad at weekly intervals) induced thymic lymphomas in C57BL/Ka mice after a latent period of 3-9 months. Meanwhile, preleukemia cells arose in the thymus and bone marrow and persisted until the onset of lymphomas. Simultaneously, thymic lymphopoiesis was impaired; thymocyte numbers were subnormal and thymic nurse cells disappeared in a progressive but irreversible fashion. The depletion of these lymphoepithelial complexes, which are normally involved in the early steps of thymic lymphopoiesis, was related to altered prothymocyte activity in bone marrow and to damaged thymic microenvironment, perhaps as a consequence of the presence of preleukemia cells. The grafting of normal bone marrow cells after irradiation prevented the development of lymphomas. However, marrow reconstitution did not inhibit the induction of preleukemia cells. They disappeared from the thymus during the second part of the latent period. At the same time, thymic lymphopoiesis was restored; thymocytes and nurse cell numbers returned to normal as a consequence of the proliferation of grafted marrow-derived cells within the thymus. The results thus demonstrated an intimate relationship between preleukemia cells and an alteration of thymic lymphopoiesis, which particularly involved the nurse cell microenvironment. Some preleukemia cells in marrow-reconstituted, irradiated mice derived from the unirradiated marrow inoculate. Thus these cells acquired neoplastic potential through a factor present in the irradiated tissues. The nature of this indirect mechanism was briefly discussed.

[more ▼] In the Western World, as many people became concerned at the potency and side effects of new drugs, there is an increasing interest in the alternative systems, including phytotherapy, and as the pharmacist must be the best qualified to advise on, and supply all drugs (e.g. herbal products) we give below our scientific opinion about the real position of plants in modern therapy. Records extant from Ancien egypt, Assyria, Greece and roma show that the use of plants for medicinal purposes exetnd back to our earliest recorded history. during the course of history, the cure of disease and the use of medicinal plants has been much influenced by religious practice and the exercise of magical rites. Thus the philosophy of the "Doctrine of Signatures" introduced by Paracelsus in the sixteenth century had considerable sway for four centuries and was not completely abandoned until the modern era of phytochemistry and pharmacology gave an alternative system for the rationalization of the use of plants in medicine. However, for most of herbal remedies, it is not still possible to demonstrate or evaluate their pharmacological activity, and the situation is complicated by the frequent use of a number of drugs in combination, the supposed active constituents of which have not been elucidated. Arising from this, orthodox medicine came to disregard sub "polypharmaceutical" preparations and concentrated research on the isolation of natural individual components having, for example, demonstrable anticancer, hypotensive ; antiplasmodial or antimicrobial properties.

In ... [more ▼] The rat pituitary tumor derived cell lines of the "GH" family offer a fruitful model for studying the expressions of the prolactin (rPRL) and growth hormone (rGH) genes in basic and regulated states. In order to assess the potential role of DNA methylation in the basic expressions of rPRL and rGH genes we have used different cell strains which produce either high level of rPRL (GH3B6 cells) or of rGH (GC cells) and minute amounts of both hormones (GH3CDL cells). The cleavage patterns generated by the methylation sensitive enzymes Hpa II and Msp I indicated an inverse correlation between the extent of gene methylation and the level of expression. However the use of 5-azacytidine which decreases DNA methylation suggested a variable importance of gene methylation in the respective control of rPRL and rGH genes depending on the cell lines. In an other hand we attempted to elucidate some of the mechanisms by which thyroliberin (TRH) enhances rPRL gene transcription in GH3B6 cells. Preliminary results indicated that the persistent occupancy of the TRH receptors was required to sustain at least for the first 5 hours the increased rate of rPRL gene transcription. In addition the possible relationship between the TRH-induced acute rPRL release and the stimulation of rPRL gene transcription was investigated. The results suggested that the activators of the C kinase-mediated pathway which are actually involved in the stimulation of the acute release were not sufficient alone for eliciting the maximum TRH response at the gene level.

An example involving a large number of vibrational channels is treated. It concerns the electrostatic autoionization in the 730-708 Angstöm wavelength region which appears in the CO photoionization spectrum. The structure observed at 721 Angstrôm is explained by the enhancement in intensity of numerous levels of Rydberg series converging to excited levels of the A 2Pi state caused by two autoionized Rydberg levels with a B 2Sigma+ core.

[more ▼] A relationship between disaccharidase and diamine oxidase (DAO) activities was looked for by measuring these enzyme activities in histologically normal small intestinal biopsies of 18 children. The range for disaccharidase activities expressed in U g-1 wet weight was 0.1-5.7, 7.1-36.7, and 2.3-8.5 for lactase, maltase, and sucrase, respectively. The range for DAO activities expressed in nmol h-1 g-1 wet weight was 202-974. Significant correlations were found between disaccharidase and DAO activities (lactase versus DAO: n = 17, r = 0.80, P < 0.001; maltase versus DAO: n = 18, r = 0.70, P < 0.001; sucrase versus DAO: n = 18, r = 0.55, P < 0.05). Our results further support the hypothesis that DAO is a marker of small intestinal functional integrity in children.

[more ▼] Under certain pathological conditions the binding of various substances by serum proteins is altered. The plasma concentrations of alpha 1-acid glycoprotein, also known as orosomucoid are reported to be elevated in stressful situation and in certain disease states like acute myocardial infarction. The binding of aminopyrine to serum proteins and alpha 1-acid glycoprotein was determined using equilibrium dialysis. It appears that alpha 1-acid glycoprotein has specific binding sites for aminopyrine. Aminopyrine was also bound to other serum proteins. On addition the results indicate that an increase of alpha 1-acid glycoprotein to concentrations such as those seen in some pathological states does not really alter the percent of aminopyrine bind to serum proteins.

The Gini index was determined as it measures the level of competition within the different markets. After a description of the index, eight products were studied : bovine meat, poultry meat, eggs in the shell, rice, sugar, tea, rubber and palm oil. For each of them, the Gini index was calculated according to the data of the Food and Agriculture Organization in 1965, 1970, 1975, 1980 and 1985. A comparison was made between the years 1965 and 1985 in order to show the evolution of the relative importance of the different exporting countries. ln conclusion, the successes, failures or changing goals of the agricultural policy of these countries could be evaluated.

[more ▼] Serum total creatine kinase (CK), CK-MB and myoglobin (Mb) were serially determined in 17 patients who underwent endomyocardial biopsy. Mean total CK levels increased from 36 +/- 27 U/l 30 min before biopsy to a maximum of 112 +/- 77 U/l 8 h following the procedure (p less than 0.05). Similarly, Mb concentrations rose from 57 +/- 55 micrograms/l to 119 +/- 57 micrograms/l 30 min after biopsy (p less than 0.05). Normalization of total CK and Mb levels occurred within 16 and 8 h, respectively. A new immunoenzymetric assay (IEMA) was used to measure the mass concentration of the CK-MB molecule. The initial CK-MB levels were 0.2 +/- 0.4 microgram/l; a small but significant elevation was recorded as early as 2 h after biopsy (1.6 +/- 1.5 micrograms/l, p less than 0.05). CK-MB returned to initial concentration 16 h after the beginning of the procedure. Comparison with the maximum CK-MB levels recorded in 16 myocardial infarction patients (258 +/- 172 micrograms/l, range 90-680 micrograms/l) indicated that the modest increase of CK-MB level detected after biopsy probably reflects a limited endomyocardium lesion at the sampling site, excluding any significant myocardial damage. Total CK and Mb, which showed more pronounced elevations than CK-MB, are likely to originate from other sources than the myocardium.

[more ▼] Clinical and pulmonary function changes induced by intravenous dichlorvos (2,2-dichlorvinyldimethyl phosphate) (DDVP) toxicosis, and reversibility of these changes after atropine treatment were investigated in six Friesian calves one to three months old. From one minute after dosage, all animals showed severe respiratory distress, excitation, weakness, muscle fasciculation and cholinesterase inhibition. Decrease in dynamic lung compliance and arterial oxygen tension and increase in total pulmonary resistance, viscous work of breathing and alveolar arterial oxygen gradient were highly significant (P less than 0.01). On the other hand, body secretions, heart rate, respiratory rate, tidal volume and arterial carbon dioxide tension were not significantly affected by DDVP injection. Atropine promptly and completely reversed these changes, except for muscle fasciculations, central depression and cholinesterase inhibition which disappeared progressively within 24 hours.

[more ▼] We have theoretically studied the electronic autoionization between 17 and 18.3 eV of Rydberg series converging to the B 2Sigma+ state of CO+ (RB series). We have obtained partial and vibrationally resolved differential and total photoionization cross sections by combining ab initio electronic quantities with a variant of the two-step multichannel quantum defect theory (MQDT). The formalism of the Feshbach projection operators is used to separate the electronic quantities needed in the first and second steps of the MQDT. We have introduced the vibrational motion within the Condon approximation. Our results lead to new unambiguous assignments of the RB series. The vibrationally resolved cross sections, the associated branching ratios, and the background and resonant features are discussed in detail and compared with the available experimental data. There is an overall agreement between theory and experiement except for the angular distribution of photoelectrons.

[more ▼] To study the effect of lung bypass on the production of prostaglandin E2, prostacyclin, and thromboxane A2, we measured simultaneously arterial and venous plasma concentrations of prostaglandin E2, 6-keto-prostaglandin F1 alpha (stable metabolite of prostacyclin), and thromboxane B2 (stable metabolite of thromboxane A2) before, during, and after cardiopulmonary bypass. Seventeen patients (age range 46 to 69 years) undergoing aorta-coronary bypass grafts were investigated. The prostaglandin E2 production rose sharply immediately after the onset of bypass (baseline: 9.7 +/- 2.9 pg/ml to 85 +/- 16.6 pg/ml in venous and 87 +/- 12 pg/ml in arterial plasma, p less than 0.03) and rapidly decreased after pulmonary reperfusion (53 +/- 6.4 and 57 +/- 20 pg/ml, respectively, in venous and arterial plasma at the end of bypass). The increase in prostaglandin E2 was influenced by the heart-lung machine itself (as demonstrated by a closed "bypass" circuit) and by lung bypass. Pulmonary metabolism of prostaglandin E2 was maintained after bypass. The prostacyclin production rose significantly at the beginning of bypass (154 +/- 26 pg/ml venous prebypass level to 361 +/- 94 pg/ml after aortic clamping, p less than 0.03). Prostacyclin decreased progressively during rewarming of the patient, pulmonary reperfusion, and discontinuation of bypass. When prostacyclin decreased, thromboxane B2 production rose significantly and reached peak arterial levels when the lungs were reperfused (112 +/- 33 pg/ml prebypass levels to 402 +/- 101 pg/ml, p less than 0.01). Except for prostaglandin E2, there were no significant differences between arterial and venous plasma levels of these substances. The same prostanoids were also measured in five patients undergoing major orthopedic operations, and no significant changes in prostanoids were observed. Our data demonstrate significant production of prostaglandin E2 in the systemic circulation during cardiopulmonary bypass in humans. They further indicate that lung bypass disturbs the plasma prostaglandin/thromboxane balance.

[more ▼] As it was previously stated by Asselberg (1971), two species of the water shrews occur in Belgium. In fact, they are not easily distinguished from each other. That is why the author studied the frequency distribution of the mandibular length and the height of the ramus mandibulae in his Neomys samples. All of them were taken from barn owl pellets originating from southern Belgium. This morphological study shows that the mandidular height is a valuable discriminant character since 99.95 % of the water shrew mandibles are higher than 4.50 mm and 99.5 of the Miller's water shrew ones are smaller than this value. The taxonomical status of the Belgian populations of N. anomalus is discussed with the clinal (N to S) size variation of this species in the mind. Finally, distribution maps are presented. The water shrew is widespread all over Belgium and Luxemburg whereas the Miller's water shrew distribution area is restricted to the Ardennes (cambro silurian and low devonian substrates) eastern of the river Meuse. The catching points of this species in Belgium are briefly described and the habitat requirements of both species commented.

[more ▼] The exact mechanism of action of beta blockers in migraine remains undetermined. An effect on the central nervous system (CNS) might be a factor. The evidence from the literature indicates that the anatomical and chemical targets for these drugs are present in the mammalian brain, that they readily penetrate the brain, and that they may modify CNS functions. The present study shows that psychomotor tests and contingent negative variation (CNV), an event related slow cerebral potential, both of which are abnormal in untreated migraineurs, tend to normalize after treatment with the beta blocker metoprolol. Moreover, a strong positive correlation was found between the amplitude of CNV and the clinical efficacy of beta blockers in migraineurs. One might hypothesize that a hyperactive central catecholaminergic state in migraine might be the common denominator between reduced performance on psychomotor testing and enhanced CNV. It remains to be determined whether this is due to hyperactivity of catecholaminergic neurons or to hypersensitivity of catecholamine receptors.

[more ▼] Experiments were conducted to further characterize the age-related decline in reproductive capability previously described in the male Japanese quail. Behavioral testing of a large number of males in several age groups confirmed earlier results that showed a significant reduction in courtship and mating behavior by 80 weeks of age. Intact males, 78 weeks of age, that showed no reproductive behavior were given Silastic implants containing testosterone. This treatment restored behavior in 80% of the males. Gonadal regression induced by exposure to shortened photoperiod followed by transfer to a stimulatory photoperiod did not successfully restore the endocrine or behavioral components of reproduction. Males of two age groups, 42 and 208 weeks of age, were categorized as behaviorally active or inactive and then castrated. Eight weeks later they were given implants containing testosterone. Older males required longer exposure time to the exogenous steroid and in some cases, an additional implant to restore mating behavior as compared to younger males. The presence or absence of behavioral activity prior to castration did not affect the length of time required for restoration of behavior. Challenge with exogenous luteinizing hormone-releasing hormone revealed that there was reduced release of luteinizing hormone in aged, behaviorally inactive males as compared to young males. Results of these experiments in addition to previous data give evidence that age-related changes occur at the level of the hypothalamus and pituitary as well as at the level of the gonads.

[more ▼] The main purpose of this critical overview of current knowledge in the field of the development of timing behavior in young children is to pave the way of future research. Traditional psycho-physiological methods have supplied coherent data on the estimation and perception of duration in children over age six. Only a few unsystematic studies have dealt with early temporal conditioning. To determine whether complex temporal regulations in the adult human are the result of a continuous process, deriving from elementary forms of temportal organization of activity, much more data are needed on infant adaptation to time, as well as on the role of language and capacities for inhibition in the evolution of temporal behavior. Furthermore, studies on the physiological bases of internal timing mechanisms and the ontogenesis of temporal regulation in young animals should help to assess the relative weight of early experience, maturation and cognitive development in the child.

[more ▼] Follicular dendritic cells (FDC) are able to fix high amounts of immune complexes by C3b or Fc receptors without endocytosis and for long periods of time. In order to determine the function of this retention, we analysed the secretion of prostaglandin E2 (PGE2) by FDC in vitro; indeed, it is well-known that immune complex fixation on cells may induce PGE2 production. FDC were isolated by enzymic digestion of lymph follicles dissected under the biomicroscope from human tonsils or adenoids. Isolated FDC appeared as spherical clusters where they enveloped lymphoid cells with their cytoplasmic extensions. Tests were performed in synthetic culture media or in media supplemented with foetal calf serum. PGE2 production in FDC suspensions was compared to that of lymphocyte or macrophage-enriched populations prepared from the same human tonsils. In all experimental conditions, FDC and macrophage-enriched cell populations produced high levels of PGE2, inversely to lymphoid cell populations. This secretion was inhibited by indomethacin. At the ultrastructural level, we also showed that 3H-arachidonic acid was metabolized in cell membranes of all three cell types. The PGE2 produced in the culture media, according to our experimental conditions, do not influence cell proliferation, as assessed by 3H-thymidine incorporation tests on phytohaemagglutinin-stimulated lymphocytes.

[more ▼] The cytoarchitectural analysis of the preoptic-anterior hypothalamic region of the Japanese quail reveals a sexual dimorphism in the total volume of the medial preoptic nucleus (significantly larger in males than in females). Different nuclei of the region (dorsal preopticus, suprachiasmaticus) do not show any statistically significant difference. The sex-related difference is more consistent comparing the distribution of dark volume. This last is due to a larger number of cells containing high amount of Nissl's substance in male than in female. Present findings represent the first example of sexual dimorphism in the avian hypothalamus.

Au départ des 36 données sélectionnées dans les statistiques du Cadastre et de l'O.N.S.S., 11 variables ont été construites. L'analyse en composantes principales a permis d'individualiser quatre facteurs rendant compte de près de 80% de la variation totale; ces quatre composantes sont représentatives de la grande industrie, de l'industrie légère, du poids industriel (part relative de l'industrie dans la commune) et des fabrications métalliques. Sur base des scores obtenus sur ces quatre composantes, il a été ensuite possible d'établir une typologie des communes en huit classes ayant chacune un profil précis, profil qui, par ailleurs, oppose sou¬vent Flandre et Wallonie, communes rurales et centres urbains.

[more ▼] Low and intermediate dispersion spectroscopy of Q0107 - 025 A and B obtained at ESO, AAT, and MMT provide evidence for spectral differences between these two quasars. A redshift difference of 0.004 is found between the two objects, and forbidden emission lines due to O II (3727 A), Ne III (1815), and possibly Ne V (3426 A), are seen in the spectrum of Q0107 - 025 A, while only the forbidden Ne III line at 1815 A is possibly detected in the spectdrum of Q0107 - 025 B. No narrow absorption lines could be detected in the 3252 - 5616 A spectral range of the intermediate resolution data of either quasar, and the spectrum of quasar B is found to be steeper in the blue that of the quasar A. The possible presence of a highly redshifted cluster of galaxies in the field of these quasars is suggested by CCD photometry.

[more ▼] Using monoclonal anti-trinitrophenyl (TNP) antibodies complexed to TNP-myoglobin-coated gold particles, we analysed at the ultrastructural level the retention by follicular dendritic cells (FDC) of immune complexes containing various antibody isotypes. Gold-labelled immune complexes were injected subcutaneously or intravenously into naive mice and, after 24 h, germinal centres of draining lymph nodes or spleen were examined by electron microscopy. FDC generally retained complexes containing IgG2a and IgG2b better than those formed with IgG1 or IgG3. IgM was rarely retained. FDC isolated from lymph nodes or spleens were incubated in vitro with gold-labelled complexes in a serum-free medium. IgG2a and IgG2b complexes were also retained in vitro in large quantities by FDC; IgG1 and IgG3 complexes were retained in smaller quantities or in highly variable quantities compared with IgG2; IgM complexes were rarely seen on FDC. There was no difference between FDC isolated from lymph nodes or from spleen with respect to the Ig isotypes required for Fc-mediated retention of immune complexes.

En effet, les bénéfices sur le plan cardiovasculaire retirés de l'abaissement tensionnel contrebalancent de loin la contrainte et les effets secondaires inhérents au traitement. Par contre, pour des PA se situant entre cette limite supérieure et 140/90 mmHg, les bénéfices globaux d'un traitement antihypertenseur sont maigres, à la lumière de vastes études épidémiologiques. Il ressort en effet que pour ce type d'hypertension (HTA) légère, la plus fréquemment rencontrée, sans répercussion systémique, on puisse postposer de quelques mois le début d'un traitement médicamenteux pour confirmer l'élévation de PA. Pendant cette période, des règles hygiéno-diététiques sont proposées et des contrôles tensionnels réguliers sont réalisés. A la fin de cette période, ceux dont la PA systolique demeure supérieure ou égale à 100 mmHg tireront avantage du traitement; par contre, pour ceux dont la PA diastolique se situe entre 90 et 99 mmHg, aucun consensus n'a pu être obtenu. Pour ce type de patients, il apparaît nécessaire d'établir un profil de risque cardiovasculaire pour sélectionner ceux qui tireront un réel bénéfice du traitement pharmacologique.

[more ▼] Thirty-three patients with common migraine underwent contingent negative variation (CNV) recordings before receiving prophylactic beta-blocker treatment with either metoprolol (27 patients) or propranolol (6 patients) at mean daily dosages of 110 mg and 122 mg, respectively. After 3 months the therapeutic efficacy of the beta-blocker was assessed in each patient by means of a global severity score and compared with the initial CNV recordings. The mean clinical improvement was 62%. A significant positive correlation was found between CNV amplitude before prophylaxis and the clinical response to beta-blockers: patients with higher CNV tended to respond better to therapy. Eight of 10 patients with a CNV amplitude higher than -25 microV had a more than 50% reduction of the severity score--that is, a good or excellent response to the beta-blocking agent--whereas only 2 of 9 patients with an amplitude lower than -20 microV had a good response.

[more ▼] In the present study, we analysed the relationships between various nucleolar components in Ehrlich tumour and HEp-2 cells, using acetylation. Under these conditions, we found contacts between the condensed intranucleolar chromatin and the fibrillar centre, illustrating the continuity between the DNA present inside the fibrillar centre and that of condensed associated chromatin. We also found that although the dense fibrillar component is usually situated at the periphery of the fibrillar centre, it is sometimes found inside the centre. On the other hand, the layer of dense fibrils bordering the fibrillar centre is interrupted by nucleolar interstices. In addition, in HEp-2 cell nucleoli with a reticulated appearance, the numerous small fibrillar centres are bound together by strands of dense fibrillar component. These observations are discussed in terms of relationships between nucleolar ultrastructure and function(s).

Immunoreactive trypsin and thromboxane were measured by radio-immuno-assay and trypsin-like enzymatic activity by spectrophotometry, using a specific chromogenic substrate. Mean IRT value was 675 ng/ml in ARDS and 265 ng/ml in non ARDS patients (p less than 0.05). Mean IRT value was 685 ng/ml in septic and 170 ng/ml in non septic patients (p less than 0.01). An abnormal trypsin-like enzymatic activity was measured in 26 ARDS patients. In 60 patients (37 ARDS and 23 non ARDS), thromboxane appeared in plasma simultaneously or about 24 hours after the beginning of IRT release. The importance of thromboxane release parallels the intensity of IRT. Originating from pancreas, trypsin can appear in plasma either by absorption from gastrointestinal tract or after pancreatic ischemia.

[more ▼] Serum creatine kinase (CK) variations during work and subjective assessments of postural discomfort were analysed in 30 workers assigned to three different tasks in a rolling mill. After four days of work, serum CK levels were significantly increased above control levels. No difference was found between the tasks studied. Inter-individual variability in CK response was large: a marked CK increase was only seen in 21 workers, while 5 workers showed a marked CK decrease. The postural discomfort sensations increased with work in each group, with their location in the body being related to the characteristics of each task or workplace. No relationship was found between the postural discomfort scores and CK changes. Results showed that determination of an individual baseline CK level was difficult to achieve in an occupational setting. It is concluded that CK variations cannot reliably be used in the field for detection of individuals exposed to excessive postural constraints. Their use as a screening tool in groups of workers assigned to similar tasks deserves further study.
