Tavern going in Canada: a national survey of regulars at public drinking establishments.

The results of a national survey of tavern going are reported; special attention is paid to the drinking patterns, reasons for attending, types of places frequented and social characteristics of the "regular" (i.e., the person who usually attends the same establishment and with some frequency). Most Canadians make some use of pubs, but only a few are regulars. Regulars are young, unmarried and heavier than average drinkers. Persons going to taverns, lounges, nightclubs and private clubs differ in social characteristics and these attributes are related to the activities and social functions associated with the various types of public drinking establishments.

[Pharmacology of "essential" phospholipids (author's transl)].

In an extensive pharmacological screening of "essential" phospholipids (EPL) antilipemic, hepatoprotective, broncholytic, as well as slight choleretic effects were found and the substance decreased capillary permeability. There was practically no influence on other functions or systems including the vegetative system (heart, circulation, respiration).

Animals

[The anti-hyperlipemic and anti-atherogenic effect of "essential" phospholipids: a pharmacologic trial].

To prove antilipemic and antiatherogenic effectiveness several animal species were given "essential" phospholipids (EPL) during different experimental procedures. The following actions were studied: 1. Effect of EPL-substance after prophylactic and therapeutic oral administration (dosage: 50, 150, 450 mg/kg bodyweight daily) in rats with acute and subacute hypelipemia induced by triton. 2. Effect of EPL-substance after prophylactic and therapeutic oral administration (dosage: 50, 150, 450, 1800 mg/kg bodyweight daily) in rats with dietetic hypercholesterolemia. 3. Effect of EPL-substance after daily oral administration (dosage: 50, 150, 450 mg/kg bodyweight) on the development of coronary and aortic atherosclerosis and various biochemical parameters in cholesterol-fed cockerels. 4. Effect of EPL-substance after dialy oral administration (dosage: 50, 150, 450 mg/kg bodyweight) on subacute triton-hyperlipemia in mini pigs. Triton-administration causes a greater or smaller increase in all parameters of the lipid metabolism measured. EPL treatment decreases these parameters during therapeutic and prophylactic administration in some cases even reaching normal values. The effect was clearly dose-dependent. EPL inhibit the increase in total lipids in dietetic hypercholesterolemia during therapeutic as well as during prophylactic administration. The effect was clearly dose-dependent in all doses, being statistically significant at the highest dosage level. In cockerels EPL were effective at all dose levels in counteracting the development of coronary atherosclerosis while the effect in atherosclerosis of aorta was less distinct. Except for non-esterified fatty acids, EPL reduced all biochemical parameters measured.

Trends in adolescent alcohol consumption in Halifax, Nova Scotia--1970-1986.

The drinking behaviours of 1,128 students from grades 7 to 12 in Halifax, Nova Scotia were surveyed and the results were compared to surveys done on similar samples of adolescents in 1970, 1976 and 1983. The survey instruments were self-administered, anonymous questionnaires administered in class groups. In the 1986 survey, while no differences (p greater than .05) in the frequency of drinking episodes exists between males and females, the former group were found to be drinking more heavily. Since 1983, the percentage of drinkers has declined significantly (p less than .05) among both sexes. The percentage of frequent drinkers (once a week or more) and heavy drinking (6+ drinks per sitting, more than once per week) has not changed significantly (p greater than .05) in either sex.
