[Sequential rearrangements of ensemble activity of the putamen neurons of monkeys as a correlate to continuous behavior].
Simultaneous recording of unit activity of 6-8 putamen neurons in two monkeys (M. nemestrina and M. mulatta) during performance of the task of alternative spatial choice, was carried out. The extent of rearrangements of the activity in the groups of neurons with the transition from every step of the behavioral program to the next one and the degree of difference in mosaics of reactivity, forming at every step with a different variants of performance, were evaluated using discriminative analysis. The rearrangements of the impulse activity were recorded in all steps of the program. The dynamics of rearrangements with the choice of right or left feeder was different, which resulted in appearance of significant differences in mosaics of reactivity at the stage of decision making and receiving reward. The rearrangements preceding the task-oriented movement of one hand were more pronounced in the contralateral hemisphere. The volume of rearrangements may increase with the performance of movement but the differences of mosaics formed during the movement of right and left hand are decreasing. At the stage of reception of the reward, the rearrangements were greater in case the animal chose the certain (left) feeder irrespective of the side of recording the unit activity.
Towards higher standards in dental and stomatological education in Europe.
In the creation of the European Union, attention was given to portability of licensure for professionals. Considerable differences exist among countries in culture, economic conditions, and educational resources and practices. In dentistry, these differences in professional training have been addressed through a peer consultative process rather than through political and legal means. The process of visits to dental schools throughout Europe and the organizational structure (DentEd) used to conduct the visits and summarize findings are described.
[Physical exercise and atherosclerosis: proatherogenic effects of high and moderate intensity static exercise on blood lipid transport system].
Effects of high (100 and 80 kg) and moderate (60 kg) intensity static leg exercise on blood serum lipoproteins and apolipoproteins (apo) A1 and B were studied in healthy subjects (n=11) and patients with coronary heart disease and class I angina (n=11). Static leg exercise with loads exceeding 60 kg were associated with atherogenic changes of blood lipid transport system: elevation of levels of triglycerides, apoprotein B and apo B/A ratio both in healthy subjects and patients, and of total and low density lipoprotein cholesterol in patients. These post exercise changes were more pronounced in the presence of fasting hyperlipidemia and their severity increased with increase in duration of exercise. Static leg exercise did not increase concentration of high density lipoprotein cholesterol. For prevention of post exercise atherogenic dyslipidemia it is expedient to supplement strength training programs with dynamic exercise of moderate intensity.
Maternal mortality in the Thyolo District of southern Malawi.
The Sisterhood Method, a community-based survey technique, was used to estimate the Life Time Risk of a woman dying a maternal death in Southern Malawi. With this figure, the maternal mortality ratio for that area was calculated to be 409 deaths per 100,000 live births. The 4124 adults interviewed reported 150 maternal deaths in sisters. An in-depth questionnaire was then used to determine that 56% of these deaths occurred outside a health facility, largely due to lack of transportation or poor access to fixed health care facilities; 25% died from excessive hemorrhage; 20% from obstructed labour; 18% from abortion; 13% from sepsis; while eclampsia accounted for only 4% of the maternal deaths. This field experience with the Sisterhood Method technique combined with an in-depth questionnaire for determining causes of maternal deaths has provided useful information in a simple and cost-effective manner for use in planning intervention strategies designed to decrease maternal mortality.
Intrauterine contraception.
Currently 85 million women use an intrauterine device (IUD), making it the most widely used, reliable, reversible contraceptive method worldwide. Although the exact mechanisms by which copper-bearing IUDs produce contraceptive action are not completely defined, recent evidence indicates that they act primarily to prevent sperm from fertilizing ova. The future of the IUD is brighter than it has been for the past 20 years. The latest generation of IUDs, such as the TCu 380A (Paragard, GynoPharma, Somerville, NJ), are safer and more effective than ever. In World Health Organization large, multicenter trials, pregnancy rates for the TCu 380A are 1.0, 1.4, 1.6, and 1.8 at 3, 5, 7, and 9 years of use, respectively. The ectopic pregnancy rates and removal for pelvic inflammatory disease are very low. The device may soon be the major IUD available in most countries. The acceptability of IUD use can be increased by good clinical management, sympathetic counseling, careful client selection, proper device selection, careful insertion, timing of insertion, and regular follow-up with quick access to medical care.
[Myocardial infarct in motor transport drivers and the results of long-term observations].
As many as 283 drivers with a history of acute myocardial infarction were examined. In the long-term postinfarction period, the number of the able-bodied accounted for 22.8%, the number of persons with restricted work fitness was 43.3%, that of the disabled amounted to 33.9%. It should be noted that about 60% of the able-bodied and those with restricted work fitness returned to the driving-related work. However, in some cases, the type of the trucking was either changed of the work scope was to be minimized. Criteria forming the basis for predicting the recovery of work fitness of the drivers were as follows: non-transmural character of myocardial infarction for the most part, the effective staged rehabilitation program, positive dynamics and smoothing of the ECG signs of myocardial infarction, the lack of areas of regional hypo- and akinesia of the myocardium, normalization of the ejection fraction, high and mean indicators of physical work fitness, exercise tolerance, coronary reserves, functional class I and II angina pectoris of effort, either the lack or initial clinical signs of circulatory failure, psychological readaptation, high occupational class, and labour orientation.
Causes and consequences of increase in child survival rates: ethnoepidemiology among the Hmong of Thailand.
The Hmong "hill tribe" minority in Thailand has much higher exposure to factors usually associated with risk of child mortality (high fertility, low status of women, low education, less use of modern medical care for births, exposure to warfare, economic and physical disruption, and poor hygienic conditions) than the rural ethnic Thai population. Nonetheless, infant mortality has declined from over 120 per 1000 to under 50 per 1000 live births among both these populations in the past 30 years. The reason for the rapid increase in child survival among the Hmong appears to be better access to and more use of modern curative and preventive medical care associated with road construction rather than major changes in social or hygienic conditions. Conventional wisdom suggests that high fertility is both a cause and a consequence of high infant and child mortality and that parents will not reduce fertility until they see that mortality has declined. Most Hmong parents recognize the decline in child mortality and attribute it to better access to modern medical care. Most Hmong parents also say that, if they were starting to have children now, they would want to have fewer children. Fear of child death is infrequently mentioned as a motive for having more children, and the perceived decline in child mortality is rarely mentioned as a reason for reduced fertility. Most Hmong parents explain their desired family size in terms of economic conditions rather than perceived risk of child mortality. Results of this study suggest that fertility and child mortality can vary independently of one another and that major reductions in child mortality can be accomplished without waiting for major social changes (e.g., improved education or status of women) or major reductions in fertility.

Abortion in Europe, 1920-91: a public health perspective.
This article grew out of a keynote address prepared for the conference, "From Abortion to Contraception: Public Health Approaches to Reducing Unwanted Pregnancy and Abortion Through Improved Family Planning Services," held in Tbilisi, Georgia, USSR in October 1990. The article reviews the legal, religious, and medical situation of induced abortion in Europe in historical perspective, and considers access to abortion services, attitudes of health professionals, abortion incidence, morbidity and mortality, the new antiprogestins, the characteristics of abortion seekers, late abortions, postabortion psychological reactions, effects of denied abortion, and repeat abortion. Special attention is focused on the changes occurring in Romania, Albania, and the former Soviet Union, plus the effects of the new conservatism elsewhere in the formerly socialist countries of central and eastern Europe, particularly Poland. Abortion is a social reality that can no more be legislated out of existence than the controversy surrounding it can be stilled. No matter how effective family planning services and practices become, there will always be a need for access to safe abortion services.
