Liver Enzyme Activities after Multiple Administration of Nifedipine in Mice

Abstract: The effect of multiple nifedipine administration on hexobarbital sleeping time, liver monooxygenase and synthetase activities, lipid peroxidation and microsomal membrane fluidity were studied in male albino mice. The drug was administered orally at a dose of 25 mg/kg daily for 14 and 21 days. Nifedipine caused enzyme induction, demonstrated by shortened hexobarbital sleeping time, enhanced ethylmorphine N-demethylase, aniline 4-hydroxylase, ethoxycoumarine O-deethylase, UDP-glucuronyl transferase, glutathione S-transferase and NADPH-cytochrome c reductase activities and increased content of cytochrome P450 and cytochrome b₅. This effect persisted until the 7th day after the last dose of nifedipine. There were no changes in lipid peroxidation and fluidity of the microsomal membranes after 14-day nifedipine administration. The increased cytochrome P450 content and drug metabolizing enzyme activities could be not associated with changes in these liver microsomal membrane properties.     

Interaction between central effects of ethanol and tricyclic antidepressants, imipramine and amitriptyline in mice and rats

The effect of a combined treatment with ethanol and imipramine or amitriptyline was tested in mice and rats. The antidepressants were given in one or, in some experiments, in 21 daily doses of 10 mg/kg each. In mice the effect of antidepressants was tested on acute toxicity, disturbances of rota-rod performance, hypothermia and sleeping induced by ethanol, in rats the effect of the antidepressants on the development of tolerance to sleep-inducing and hypothermic action of ethanol was investigated. Amitriptyline showed a tendency to pontentiate the ethanol-induced acute toxicity, while imipramine did not change it. Given in a single dose the antidepressants have a tendency to potentiate the impairment of motor coordination induced by ethanol, but after a prolonged administration did not influence the ethanol effect in the rota-rod test. The antidepressants enhance ethanol-induced hypothermia and prolong the ethanol sleeping time. The development of tolerance to hypnotic effect of ethanol in rats is not affected by amitriptyline and imipramine, but the antidepressants prevent the development of tolerance to hypothermic effect.     

General pharmacology of the novel angiotensin converting enzyme inhibitor alacepril. 2nd communication: Effects on central nervous and sensory systems and on the other functions

The effects of 1-[(S)-3-acetylthio-2-methylpropanoyl]-L-prolyl-L-phenylalanine (alacepril, DU-1219), an orally active angiotensin converting enzyme inhibitor, on the central nervous and sensory systems and on several other functions were compared with those of captopril in the experimental animals. Alacepril at the high oral dose of 600 mg/kg prolonged the hexobarbital sleeping time and potentiated the reserpine-induced hypothermia in mice. However, alacepril at the same dose did not affect the general behavior, convulsions induced by maximal electroshock, pentetrazol and strychnine, active avoidance in mice and body temperature in rats. In addition, alacepril (200 mg/kg i.v.) has little effect on general behavior in mice. Captopril at over 107 mg/kg p.o. produced eyelid closure and at 320 mg/kg prolonged the hexobarbital sleeping time. A metabolite of alacepril, desacetylalacepril (DU-1227) (200 mg/kg i.v.), caused salivation in mice. Alacepril and DU-1227 at 60 mg/kg i.v. were without effect on flexor reflex and spontaneous electroencephalogram (EEG) in cats, while captopril at the equimolar dose depressed the flexor reflex and showed a tendency to increase the beta 2-band relative power of the cortical EEG. Alacepril and captopril neither affected the writhing syndrome induced by acetic acid nor that by phenylquinone in mice. Local anesthetic and irritant activities in rabbits and effect on neuromuscular junction in anesthetized rats were not observed with the two compounds. Alacepril at the oral dose of 0.1 mg/kg potentiated the carrageenin-induced edema in rats. However, the effect was one third that of captopril. Alacepril and captopril did not affect the increased vascular permeability by acetic acid in mice.(ABSTRACT TRUNCATED AT 250 WORDS)

柏子仁总萜类成分药理活性及提取工艺研究

目的探讨从柏子仁中提取总萜类成分的最佳工艺及总萜类成分的镇静、催眠和耐缺氧作用。方法以均质时间、温度、料液比和次数4个因素进行考察,每个因素3个水平,采用L9(34)正交试验优选提取工艺。观察柏子仁总萜类成分对小鼠自发活动、戊巴比妥钠诱导小鼠睡眠时间和睡眠个数及缺氧小鼠存活时间的影响。结果以甲醇溶液作为提取溶剂,提取温度80℃,料液比1∶10,均质10 min,均质提取1次为最佳提取工艺;总萜类成分能抑制小鼠的自发活动,延长戊巴比妥钠诱导的小鼠睡眠时间,增加小鼠睡眠个数,延长缺氧小鼠的存活时间。结论柏子仁总萜类成分具有镇静、催眠和耐缺氧作用;提取方法应用均质法操作简单、效率高,适用于柏子仁总萜类成分的提取。     

Influence of captopril and enalapril on some central effects of ethanol

The influence of captopril and enalapril on acute toxicity of ethanol, ethanol-induced hypothermia, ethanol sleeping time has been investigated in mice. Moreover, the combined effect of captopril and enalapril on spontaneous locomotor activity in mice has been examined. The captopril (5 and 20 mg/kg) and enalapril (5 and 20 mg/kg) were injected intraperitoneally i.p. The drugs were given as single or repeated doses for 10 days. It has been shown that the captopril and enalapril administered in single doses decreases, but chronic administration increases acute toxicity of ethanol. Captopril and enalapril in single doses enhanced, but chronic administration inhibits hypothermic effect of ethanol. Captopril and enalapril reduces ethanol sleeping time. Captopril and enalapril administered for 10 days and enalapril in a single dose 20 mg/kg decreases ethanol induced hyperactivity.     

滴滴涕和六六六对戊巴比妥体内转化的双相影响

Influence of fluoroquinolones on the central action of ethanol.

The influence of ciprofloxacin, ofloxacin and pefloxacin on acute toxicity of ethanol, ethanol-induced hypothermia, ethanol sleeping time was investigated in mice. Moreover, the combined effect of fluoroquinolones and ethanol on spontaneous locomotor activity, motor coordination in mice and ethanol abstinence syndrome in rats was examined. The fluoroquinolones (20 and 80 mg/kg) were injected intraperitoneally. The drugs were given in single or repeated doses for 7 days. In acute experiments, drugs were given 30 min before ethanol administration. In chronic experiments, the last dose of fluoroquinolones was given 18 h prior to ethanol injection. It has been shown that the fluoroquinolones decrease acute toxicity of ethanol, antagonize its hypothermic effect, decrease ethanol inhibitory effect on motor coordination in mice, and increase ethanol-induced hypermotility in mice and audiogenic seizure response in rats during alcohol abstinence syndrome. Ciprofloxacin and ofloxacin administered repeatedly increase the influence of ethanol on duration of ethanol-induced sleep. The influence of fluoroquinolones on ethanol central action depends on the drug used, its dose and route of administration.
