  • Recently, obesity has become a worldwide public health concern and the use of anorectic drugs has drastically increased. In this study, sibutramine and phendimetrazine, representative marketed anorectics, were repeatedly administered per os on a daily basis into C57BL/6 mice and the effects of these drugs on food intakes, body weight changes and gene expression profiles were monitored for up to following 7 days. Methamphetamine, which has a potent anorectic effect, was used as a positive control. Anorectic effects were sustained only for two days by phendimetrazine or methamphetamine, but for six days by sibutramine. The modulations of gene expressions in the hypothalamus and the striatum were investigated using microarrays on day 2 and day 7 post-administration, which corresponded to the anorectic period and a return of appetite respectively, for all three drugs tested. Differences in overall gene expression profiles in the stratum on day 2 for sibutramine and phendimetrazine seems to reflect difference between the two in terms of the onsets of drug tolerance. According to microarray findings, the Ankrd26 gene appears to have an important anorectic role, whereas the up-regulation of the olfaction system appeared to be involved in the drug tolerance of anorectics. The microarray data presented in this study demonstrates the usefulness of gene expression analysis for gathering information on the efficacy and safety of anorectic drugs.

  • The general and some pharmacological actions of DWP 302 were investigated in animals and the following results were obtained. In central nervous system, DWP 302 had no effects on the pentobarbital induced anaesthesia, locomotor activity, rotarod test, traction test, analgesic action in the mice and body temperature in the rat. DWP 302 showed no depressive action on the convulsion induced by strychnine and electronic shock. From these results, DWP 302 was considered to have no or little pharmacological effect on the central nervous system. Furthermore, DWP 302 had no influences on the normal blood pressure and heart rate. In the isolated ileum of guinea pig, DWP 302 showed neither contractive nor relaxing effects against the acetylcholine ($10^{-6}g/mι$), histamine ($10^{-6}g/mι$) and $BaCl_2$ ($10^{-4}g/mι$) at a concentration of $1.9{\times}10^{-4}g/mι$ in bath. But it caused a slight increase in basal tone at a concentration of $6.3{\times}10^{-4}g/mι$ and this effect was inhibited by atropine $10^{-7}g/mι.$ In the isolated trachea and vas deference, DWP 302 showed no effect on the contractions produced by histamine and norepinephrine, respectively. And DWP 302 showed no effect on the contractions produced by acetylcholine and oxytocin in the isolated nonpregnant rat uterus. DWP 302 had no effect on bile excretion, urine volume, pH and gastrointestinal motility, But, DWP 302 showed a significant inhibitory effect on gastric secretion in the rat.

  • The purpose of this study was to evaluate the effects of the non-pharmacological intervention on depressive symptoms in the older adults with mild cognitive impairment. A total of 1,147 studies were retrieved from PubMed, CINAHL, PsycINFO, Science direct, KISS, RISS, and DBPia. Twenty-one studies which met the criteria were selected and the quality assessment was conducted independently by two investigators. The effect size of non-pharmacological intervention was estimated using Comprehensive Meta-Analysis 3.0. The overall effect size turned out to be the medium effect size (Hedges' g=-0.68, 95% CI=-1.01~-0.36). As a result of the subgroup analysis, the intervention type was statistically significant. The effect size of cognitive intervention (Hedges' g=-1.03, 95% CI=-1.43~-0.61) and multi component intervention (Hedges' g=-0.97, 95% CI=-1.63~-0.33) was greater than excise intervention (Hedges' g=-0.53, 95% CI=-1.16~0.03). This study shows that non-pharmacological intervention was also effective in reducing depressive symptoms in the older adults with mild cognitive impairment. Based on the research results, it is expected that various non-pharmacological intervention studies will be attempted to improve cognitive function and depressive symptoms of the older adults with mild cognitive impairment.

  • The general pharmacological actions of recombinant human growth hormone (rHGH) were investigated. It had hypothermic action but neither sedative nor analgesic action. No pharmacological effects were observed in isolated guinea pig ileum and tracheal muscle and rat fundus and uterus. Slight hypotensive action with no effect on respiration was revealed at a dose of 20 IU/kg i.v. of rHGH in rabbits. The rHGH exhibited a weak inhibitory action of glucose tolerance in normal rats, significantly lowered the blood glucose contents in adrenalectomized rats 20 min after i.v. administration (80IU/kg), and produced a significant inhibitory effect on in vitro glycerol release in epinephrine-stimulated epididymal fat pad segments of rats.

  • The ethanolic extract of Fleurya interrupta Gaud, (Urticaceae) was tested for its possible neuropharmacological effects on experimental animals, For the primary neuropharmacological screening of this plant, the ethanolic extract of its aerial parts was subjected to preliminary evaluation for acute toxicity, antinociceptive activity and central nervous system (CNS) activities. At the doses of 125 and 250 mg/kg, the extract significantly (P < 0.01 and P < 0. 001) and dose-dependently increased the frequency of acetic acid induced writhing in mice. In the pentobarbitone induced sleeping time test, the extract at the above dose levels, significantly and dose-dependently decreased the pentobarbitone induced sleeping time (P < 0.001) and increased the time for onset of sleep (P < 0.001) in mice. In the open field and hole cross tests, test animals showed an increase in their movement in the both tests from the 2nd observation period (30 min) and persisted throughout the entire experimental period (240 min). These results of the extract may attribute a stimulating action on the CNS. On the basis of these findings, it can be assumed that the extract exerts its stimulating effect on the CNS in mice by interfering with the cortical function or increasing the effect of some CNS stimulating neurotransmitters.

  • The general pharmacological properties of GCSB-5, a herbal formulation consisting of 6 Oriental herbs(Ledebouriellae Radix, Achyranthis Radix, Acanthopanacis Cortex, Cibotii Rhizoma, Glycine Semen and Eucommiae Cortex), were investigated in mice, rats, guinea pigs and rabbits. The administration of GCSB-5 had no effect on general behavior, and did not influence the central nervous system. Mean blood pressure, heat1 and respiratory rate and contractile response of the isolated guinea pig atrium were unaffected by the treatment of GCSB-5. Addition of GCSB-5 did not cause spontaneous relaxation and contraction of the isolated guinea pig ileum and rat uterus. And also, GCSB-5 had no effect on the gastrointestinal system and the blood system of the animals examined in this study. GCSB-5, at higher doses(1,000 and 3,000 mg/kg), increased the urinary excretion of electrolytes, however, the urine volume and pH in rats were unaffected. Taken together, these results indicate that GCSB-5 does not induce any adverse effects in experimental animals and is expected to have no significant general pharmacological activities.

  • Bufonis Venenum is a toad venom and its main components are bufadienolides, namely resibufogenin, bufalin and cinobufagin. The desensitizing effect of Bufonis Venenum is useful for the treatment of the premature ejaculation in Chinese medicine. But, minor components of Bufonis Venenum cause problems such as topical burring, pain, and erectile dysfunction. To clarify and eliminate the components responsible for these side effects, we prepared two extracts of Bufonis Venenum with either 70% ethanol or ethylacetate and tested their pharmacological effects. The extract of Bufonis Venenum with 70% ethanol produced pain response in rat hind paw, and exhibited contraction of rabbit corpus cavernosal muscle in vitro. On the other hand, the ethylacetate extract did not cause pain and smooth muscle contraction. The desensitizing effect of the ethylacetate extract was similar to that of the 70% ethanol extract. In conclusion, these results show that the extract of Bufonis Venenum with ethylacetate does not have the components causing side effects and deserve further study for therapeutic potential in premature ejaculation in men.
