    Notes: In the freshwater area of Vietnam's Mekong Delta, Barbodes gonionotus (Bleeker), Cyprinus carpio L. and Oreochromis niloticus (L.) are often reared together in rice fields. The survival rate and specific growth rate (SGR) of C. carpio showed a large variance. To understand the underlying reasons for this variation, we used multiple regressions for the variables SGR and survival rate, using the results of eight experiments in such polycultures at the Co Do rice–fish experimental station. The SGR of C. carpio declined with increasing rice density. Interspecific competition with O. niloticus also had a negative effect on C. carpio SGR. When fertilizer or manure is added to the trench of the rice–fish field or when extra food can be given to the fish, O. niloticus seems more appropriate than C. carpio. The survival rate of C. carpio depended on season, C. carpio stocking weight and density and the biomass of wild fish species. To obtain higher survival rates, one should stock fewer fish but of a larger size, after thorough eradication of wild fish species.

    Notes: Summary The pharmacokinetics and bioavailability of diacetolol, the principal metabolite of acebutolol, were studied in 6 healthy subjects. Plasma concentrations were determined following a single intravenous injection of diacetolol 100 mg and three oral doses of diacetolol 100, 400 and 800 mg, in random order. The average oral bioavailability of diacetolol was F: 0.302±0.052 (100 mg), 0.363±0.052 (400 mg) and 0.426±0.068 (800 mg); the differences are not significant. The mean plasma half-life of the terminal phase, 7.94±0.26 h after intravenous administration, was significantly higher than after oral administration 12.27±1.00 h (100 mg), 12.82±1.59 h (400 mg) and 13.05±1.22 h (800 mg) (p〈0.02 to 0.05); the mean urine half-lives of the terminal phase were not significantly different. Renal clearance of diacetolol 10.2±0.81·h−1 represented about two-thirds of total body clearance 15.9±1.21·h−1. The results suggest either a first-pass effect or incomplete absorption of diacetolol after oral administration.

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The effects of ketanserin (40 mg p.o.) on blood pressure and brachial haemodynamics (brachial artery diameter, brachial blood velocity and blood flow) have been compared in a double-blind study with those of ritanserin (10 mg p.o.) and placebo. Haemodynamic parameters were measured before and 1 h after treatment. Patients with mild to moderate essential hypertension participated in this study, 6 each on ketanserin, ritanserin and placebo. Placebo significantly reduced heart rate and did not modify the other parameters. Compared to placebo, ketanserin significantly reduced systolic and diastolic blood pressure, increased brachial blood velocity and flow, and decreased forearm vascular resistance. Compared to placebo, ritanserin slightly decreased blood pressure and slightly increased blood flow, but neither effect was significant. When blood circulation to the hand was excluded, neither ketanserin nor ritanserin modified the proximal arterial resistance or blood flow. It is concluded that the actions of ketanserin and ritanserin essentially occurred in the distal part of the upper limb, and alpha1-receptor blockade is probably involved.

    A new display technique for computer-processed digital scans (1977)

    Notes: Abstract This article presents a new approach for presenting scintigraphic images. The technique combines the conventional plotting of contour lines and the highlighting, by means of hatching, of the concavities (or convexities) of the ‘surface’ representative of radioactive distribution. The search for the surface features is achieved generally by the method for normal curvatures. An example with a phantom demonstrates the utility of this representation method.

    Personality self-representations of patients with hand injury, and its relationship with work injury (1995)
    Springer
    European journal of epidemiology 11 (1995), S. 373-382

    Keywords: Hand lesion ; Injury ; Personality self-representations ; Patients
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract This study compared the personality self-representations of 288 hand injured patients with those of 959 young people (15–25 years old) randomly selected from the general population (noted GP), and with those of 336 unemployed people of all ages in professional training (U) in Lorraine (north-eastern France). The relationship between patients' personality self-representations and injury was also investigated. Personality self-representations included 14 questions: in your own opinion are you sociable?, at ease with others?, serious?, careful?, dynamic?, optimistic?, worried?, irritable?, clumsy?, solitary?, organised?, ambitious?, do you have a sense of responsibility?, and many plans? The patients had similar self-representations to GP except for the items non clumsy (odds ratio adjusted on age and sex OR=2.40,p〈0.05) and optimistic (OR=1.70, but 0.05〈p〈0.10). The frequencies of non irritable, non clumsy and non solitary people were higher in patients than in the U group (OR about 2.40,p〈0.01). By contrast, the other items were more favourable for the U group except for the items sociable, organised and having many plans. Self-representation items were significantly related to some socio-demographic data. The work injured workmen having one or more previous work injuries during the last five years were more at ease with others than the other subjects. Among the work injured workmen who had had no previous work injury during this time, the people aged 29 or less (the highest risk age class) were more optimistic than the others (71% vs 49%,p〈0.05); a difference was also found for the items at ease with others, careful, dynamic, and non worried, but it was not significant possibly due to the small number of subjects. The sum of these five items differed between the two age groups (3.29±1.49 vs 2.55±1.68,p〈0.05). These simple items would provide an interesting approach in terms of personality which could explain in part the excess of work injuries in young people, though the work requirement still seemed to be the highest risk factor.

    Asymmetry correction equations for hand volume, grip and pinch strengths in healthy working people (1998)
    Springer
    European journal of epidemiology 14 (1998), S. 71-77 
    Details
    ISSN: 1573-7284
    Keywords: Asymmetry correction ; Hand strength ; Hand volume ; Healthy people
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Assessments of oedema and decrease in hand strength are useful for patients with a hand lesion. This study examined the asymmetry of the arms and determined the estimates of the unknown prior to lesion values for hand volume, grip strengths assessed with a Jamar dynamometer (GSJ) and a Collins dynamometer (GSC), and pinch strength with a Jamar pinch gauge (PS) in 100 healthy working people. Hand volume, GSJ, GSC, and PS of the dominant hand were respectively 3.6 ± 4.1%, 6.6 ± 9.2%, 11.7 ± 11.2%, and 8.0 ± 13.2% higher than those of the non-dominant hand (p 〈 0.001). Very good estimates were obtained with the values of the contralateral arm for all the indices studied. The correlation coefficient equalled 0.95 for hand volume, 0.91 for GSJ, 0.83 for GSC, and 0.72 for PS. These estimates allow us to evaluate the evolution of oedema and hand strengths in patients with hand injury, especially to determine whether they could return to work as they are mostly manual workers with demanding jobs.

    Notes: Abstract In 1989, the French PCV-METRA Group (PCV-METRA = Prévention Cardio-Vasculaire en Médecine du Travail) started a large prospective survey of cardiovascular (CDV) morbidity and mortality and of CVD risk factors, especially cholesterol, in a working population in Ile-de-France, a region including Paris. This report presents the first results of this study, based on a sample of 5758 men and 2603 women, aged 18–65 years. The variables examined included the levels of total cholesterol (TC), High-density-lipooprotein cholesterol (HDL-C), low-density-lipoprotein cholesterol (LDL-C), and the other major CVD risk factors (smoking, sedentary way of life, hypertension, hypercholesterolemia, use of oral contraceptives and familial history of CVD risks). TC and LDL-C significantly increased with age. The changes with age were significantly different in men and women. The levels were similar in both sexes at less than 30 yrs, increased sharply for men after age 30 and were significantly higher in men than in women from 30 to 55 yrs. Beyond 55 yrs, no difference was obserbed between the two sexes. In contrast, HDL-C was higher in women at all age ranges. In the total sample, 35% of men and 21% of women were hypercholesterolemic (TC ≥ 2.4 g/ L). Our observations fully confirm and refine previous findings in the US and in other European countries. In addition, a substantial set of data on CVD risk factors for the working population in France, especially for female subjects for whom data are scanty, is now available.
