  • The influence of debrisoquine on pressor actions of norepinephrine (NE) and tyramine (TR) was investigated in rabbits. Debrisquine(D), in the doses of 1.0, 3.0 and 6.0.mu.g/kg, i.v. potentiated significantly the pressor actions of NE and TR, except the action of TR in the dose of 1.0mg/kg of debrisoquine. NE response potentiated by debrisoquine was not affected by tranylcypromine, a MAO inhabiter, or desipramine, a NE uptake blocking agent, but augmented by reserpine, a NE depleting agent, or bethanidine, a sympathetic neuronal blocking agent. NE response potentiated by tranylcypromine or desipramine was augmented by debrisoquine, while NE response potentiated by reserine or bethanidine was not affected by debrisoquine. TR response potentiated by debrisoquine was weakened by tranylcypromine, desipramine or reserpine, and not affected by bethanidine. TR response in rabbit pretreated with tranylcypromine, desipramine or reserpine was augmented by debrisoquine, but in rabbit pretreated with bethanidine was not affected by debrisoquine.

  • Objectives This study aims to develop valid experimental models for depression through chronic reserpine exposure to zebrafish (Danio rerio). Methods The effect of chronic reserpine on zebrafish behavior in the novel tank was examined. Changes of gene expression on telencephalon were also investigated. Results Chronic reserpine (40 mg/L, 7 days) induced overt behavioral effects, but markedly reduced activity, resembling motor retardation in depression. In telencephalon of zebrafish, gene expression associated with monoamine oxidase and norepinephrine transporter was decreased. Expression of serotonin transporter gene was increased. Conclusions Our results show that the pharmacological model of depression in zebrafish can induce not only behavioral changes, but also monoamine changes in the homology of human mood regulation centers.

  • Majarine that was isolated from Berberis Koreasra Palibin (Berberidaceae) is the isoquinoline alkaloid. The effects of dopaminergic and serotonergic antagonists on majarine induced changes in body temperature were studied in the mouse. Intraperitoneal administration of majarine produced dose-dependent hypothermia. At a dose of 0.1 mg/kg, majarine caused a slight increase in body temperature. Majarine-induced hyperthermia was attenuated by the 5-HT antagonist, cyproheptadine However, it caused hyothermia in mice pretreated with the DA antagonist, haloperidol, and hyperthermia in mice pretreated with haloperidol and cyproheptadine in comparision with haloperidol pretreatment. At a dose of 2.0 mg/kg, majarine-induced hypothermia was attenuated by haloperidol and cyproheptadine, respectively. In reserpine pretreated mice, majarine produced dose-dependent hypothermia. At a dose of 0.1 mg/kg, majarine pretreated with haloperidol caused no significant effect in body temperature. At a dose of 2.0 mg/kg, majarine-induced hypothermia was attenuated by haloperidol pretreatment in mice treated with reserpine and ${\alpha}$-methyl-p-tyrosine. These data suppose that both dopaminergic and serotonergic mechanisms in the brain mediate the effects of majarine on body temperature. We propose that majarine directly stimulate DA receptor, which secondarilly activate 5-HT neurons to cause changes in body temperature.

  • Besides it's all important analgesic action, morphine has, among others, hyperglycemic effect, though not important clinically, which is believed to be resulted from augmented glycogenolysis in the liver and muscles due to the increased liberation of epinephrine from the adrenal medulla upon the stimulation of the posterior part of hypothalamus. It is known that adrenergic blocking agents are acting inhibitory to this sort of hyperglycemia. Much, however, should as yet be studied for the drugs which affect central nervous system and release of endogenous catecholamine as far as their effects on hyperglycemia are concerned. Much is still not known about the effect of ginseng, which has been highly regarded in the Herb Medicine, as far as it's influence on the blood sugar is concerned. Author investigated the effects of chlorpromazine, reserpine and ginseng on epinephrine induced, and morphine-induced hyperglycemiae. Animals used in this experiment were healthy albino rabbits weighing approximately 2.0 kg of body weight and were all fasted for 24 hours, before the experiment undertaken. Blood sugar determination was carried out by Nelson-Somogy method. Results obtained are summarized as follows; 1. The groups of rabbits administered intravenously with epinephrine 0.02 mg/kg, and 0.05 mg/kg, showed marked and transient hyperglycemia within 15 minutes after injection. The maximal rate of elevation in blood sugar to the control level, were 28% and 57% respectively. The blood sugar returned to the control level within 3 hours. Thus, the hyperglycemic responses were paralleled with epinephrine doses. 2. The hyperglycemic responses by morphine were different according to the doses. The groups of rabbits in which 4 mg/kg of morphine was administered, did not show any hyperglycemic effect, but, in which 10 mg/kg of morphine administered, showed severe hyperglycemic effect, resulting in the maximal level within 2 hours after injection. The maximal rate of increasing in blood sugar ,level was 88%. Compared .with epinephrine-injected groups, morphjne-injected groups showed more persistent hyperglycemic effect, but returned to control blood sugar .level in 6 hours after injection. 3. The intravenous injection of chlorpromazine 2 mg/kg and 8 mg/kg evoked a slight, and persistent hyperglycemia. The maximal rate of increasing in blood sugar level were 15% and 23% respectively. These hyperglycemia gradually returned to the normal level in 5 or 6 hours after injection. Thus, the intensity of response was paralleled with the dose of chlorpromazine. 4. The intravenous injection of reserpine 0.2 mg/kg and 0.5mg/kg, showed the most persistent but steady elevation of blood sugar level in this experiments, resulting in the maximal level in 5 hours after injection. The maximal rate of increasing of blood sugar level were 18% and 39% respectively. 5. The blood sugar level from 24 hours to 30 hours after intraperitoneal administration of reserpine 1.0mg/kg, did not show statistically significant difference, compared with control groups. 6. The oral administration of ginseng extract 15 ml/kg did not. show any :change in blood sugar level. 7. The intravenous administration of epinephrine 0.05 mg/kg or morphine 4 mg/kg to the group pretreated with ginseng extract 15 ml/kg $20{\sim}30$ minutes before the experiment, evoked more marked hyperglycemic effect than the non-pretreated group. 8. The intravenous administration of epinephrine 0.02 mg/kg, morphine 4 mg/kg, or morphine 10 mg/kg to the groups pretreated with reserpine 0.2 mg/kg or 0.5 mg/kg $20{\sim}30$ minutes before experiment, produced more marked and persistent hyperglycemic effects than the groups injected with single epinephrine or morphine injection. 9. When epinephrine 0.05 mg/kg or morphine 10 mg/kg administered intravenously to the groups pretreated with the intraperitoneal administration of reserpine 1 mg/kg 24 hours before experiment morphine-induced hyperglycemia was inbibited, but epinephrine-induced hyperglycemia was augmented. 10. When epinephrine 0.05mg/kg or morphine 10 mg/kg administered intravenously to the groups pretreated with chlorpromazine, 2 mg/kg, 4 mg/kg, and 8 mg/kg $20{\sim}30$ minutes before the experiment, morphine-induced hyperglycemia was inbibited, but epinephrine-induced hyperglycemia was more persistent.

  • Previous work in our laboratory has shown that noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonists, MK-801, ketamine, dextrorphan and dextromethorphan cause a pronounced inhibition of apomorphine-induced cage climbing behavior in intact mice, suggesting the involvement of NMDA receptors in the glutamatergic modulation of dopaminergic function at the postsynaptic dopamine (DA) receptors: Therefore, in order to definitively establish the involvement of NMDA receptor in the apomorphine-induced dopaminergic response at the postsynaptic DA receptor, it is necessary to investigate whether or not the noncompetitive NMDA receptor antagonists would inhibit these phenomena not only in intact mice but also in the mice that are devoid of any involvement of indirect dopaminergic function. To minimize the risk of any indirect involvement of NMDA antagonists with DA neurons, vesicular DA stores were first depleted with reserpine.

  • Successful induction of lactation in 5 nulliparous repeat breeding cows was achieved by administering diethyl stillboestrol (0.1 mg/kg B.W.) and hydroxyprogesterone caproate (0.25 mg/kg B.W.) for 3 days followed by reserpine (4 mg/day) for 4 days, and dexamethasone (16 mg/day) for one day. The treatment caused cystic ovarian condition in all the animals. Intravaginally progesteronesoaked sponges suppressed but did not eliminate the behavioural estrus. Administration of LHRH ($300{\mu}g$) regressed the cysts in all animals in the first instance but the cysts reappeared in 2 animals. One animal became pregnant and delivered a normal calf.

  • Higenamine is an Aconiti tuber derived compound whose chemical structure is 1-(4'-hydroxybenzyl)-6, 7-dihydroxy-1, 2, 3, 4-tetrahydroisoquinoline containing catechol ring and tetrahydroisoquinoline nucleus in its own structure, both of which are well known to have agonistic effects on adrenergic receptors. Using guinea-pig atria(rich in ${\beta}_1$-receptor) and treachea(rich in ${\beta}_2$-receptor), we studied pharmacological actions of higenamine on these organs with special interest of its relevancy of ${\beta}$-receptor selectivity. In order to further clarify its pharmacological characteristics, the influncences of pretreatment of reserpine or cocaine were also investigated. The results were summarized as follows : 1. Higenamine had remarkable chronotropic, inotropic and bronchodilator effects in guinea-pig spontaneously beating right atria, left atria and trachea, in dose-dependent manners. 2. All of above actions were blocked competitively by propranolol, which shows nonselectivity of higenamine on ${\beta}$-receptor. $pA_2$ values of propranolol against higenamine were 7.93, 7.76 and 8.46 in guinea-pig right atria, left atria and treachea, respectively. 3. Reserpine pretreatment(5mg/kg, ip, 24h) did not show my decrease in pharmacological actions of higenamine, which suggests higenamine has direct action on ${\beta}$-receptor not via catecholamine release. 4. Cocaine pretreatment$(1{\mu}M)$ had no influence on pharmacological actions of higenamine in contrast with nor epinephrine, which suggests there is no neuronal uptake mechanism of higenamine in the studied organ preparations.
