The positive rate of anti-HCV was as high as 16.4% by C100-3 and much higher by HCV-2nd as 33.2%. The incidence of cases with the history for blood transfusion, drug addict and/or tattoos in alcoholics was as high as 39.4% (89/226). To clarify the influence of the background such as blood transfusion, drug addict and/or tattoos on HCV infection, the positive rate of anti-HCV was compared between those with the background and without the background. In alcoholics without the backgrounds, the positive rate of C100-3 and HCV-2nd were significantly (p less than 0.001) higher than patients without the backgrounds, namely 27.0% vs 9.5%, 56.2% vs 18.2%, respectively. In alcoholics without the backgrounds, the positive rate of anti-HCV became higher in proportion as the age of the patients grows older from 20 to 60 years. These results suggest that a high incidence of HCV infection in alcoholics may resulted from increased the backgrounds that can provide chances of HCV infection and that in those without the backgrounds, alcohol and aging may lead the tolerance to HCV infection.</p>","PeriodicalId":77015,"journal":{"name":"Arukoru kenkyu to yakubutsu izon = Japanese journal of alcohol studies & drug dependence","volume":"27 2","pages":"180-8"},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12491254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Actually, determination of \"influence of alcohol\" is based on the standard set by the Cabinet Order that alcohol level exceeds 0.5 mg/ml of blood or 0.25 mg/l of expiration. In 1988, number of traffic accidents by drunken driving is 4,808 cases. Among the accidents by drunken driving the rate of fatal causes is 12%. During about last ten years, both of accidents and fatal cases by drunken driving have been decreasing in number, on the other hand, charged or cited number of violation involved \"driving under the influence of alcohol\" has been increasing. This fact indicates that the concept of seriousness of driving after heavy drinking has been diffused over Japanese nation, but there is still a tendency among drivers to consider the effect of alcohol on driving operation to be negligible when light drinking. In a sobriety checkpoint, alcohol field test are carried out on breath to screen out impaired driver. The most common device used in Japan is an alcohol detector tube, in which cerite particles coated with chromate are packed. The scale on the detector tube is marked to show a value that is lower by 20% than the actual value concerning its inaccuracy.

In order to reduce such problem, we assessed effects of a preparation containing theophylline (THEO) as the substitution of CAF, and dihydrocodeine (2HCOD), methylephedrine (MEPH) and chlorpheniramine (CPA) on ambulatory activity and discrete lever-press avoidance response in mice. It is well known that THEO is less potent in the central action than CAF, but its relaxant action on smooth muscle is about 2 times as potent as that of CAF. Therefore, the dose of THEO administered was half of that of CAF. A significant increase in the ambulatory activity was produced by the administration of CAF and/or mixed preparations, in which CAF was contained with 2HCOD, MEPH and CPA at the same doses with those in BRON 10 ml/kg. The ambulation-increasing effects of THEO and THEO-containing preparations were less potent than those of CAP and CAF-containing preparations. Furthermore, repeated 5 times administration of CAF-containing 4-drug preparation (CAF + 2HCOD+MEPH+CPA) elicited a progressive enhancement of the ambulation-increasing effect. Whereas, almost the same effect was reproduced throughout the 5 times administration of THEO-containing 4-drug preparation (THEO + 2HCOD+MEPH+CPA). The discrete lever-press avoidance response was disrupted (i.e., decrease in the avoidance rate) by CAF-containing preparations.
