  • Neutropenia is a major dose-limiting factor in cancer chemotherapy diminishing its usefulness and increase patient's susceptibility to infectious disease. Some recombinant human granulocyte colony stimulating factors(rhG-CSFs) are in use to reduce the risk of this serious side effect. In this study, we examined the pharmacological properties of DA-3030, a rhG-CSF expressed in E. coli. DA-3030 100 and $\mu\textrm{g}$/kg, i. v., had no significant effect on the central nervous, gastrointestinal system in mice and cardiovascular system in rabbits, but it slightly inhibited the spontaneous motility of isolated nonpregnant uterus in rats. It also had no influence on excretion of urinary electrolytes. DA-3030 administered for successive 3 days increased the blood WBC count in zymosan air pouch inflammed rats and in normal rats. These results indicate that DA-3030 has little side effects in animals.

  • Syndecans are membrane-anchored proteoglycans and implicated in the pathogenesis of cancer progression and metastasis. Syndecans also play important roles in interacting with growth factors, extracellular matrix and other cell surface molecules such as IGF-1 receptor. In the present review, we discuss about the syndecan structure, their role in signaling with other receptors, in addition to its general biology. The emerging roles of syndecans in the pathophysiology of human diseases, especially insulin resistance, diabetes and cancer is discussed.

  • To see if the treatments of d-amphetamine and chlorpromazine have any influence upon the orienting response and general behavioral activity, 3 groups of male Holtzman rats were prepared, namely d-amphetamine animals (1.0 mg/kg.i.p.), chlorpromazine rats (1.0 mg/kg.i.p.) and the physiological saline control animals. The general behavioral activity was examined by visual scanning using the time-sample method in the adaptation period of orienting response. The occurence of orienting response and its rate of habituation were evaluated by observing cessation of ongoing activity in response to a sound stimulus (1,000 Hz, 70 db & 0.1 sec), or turning of head toward the source of stimulus in 20 trials. Attention shift from sound to light stimulus was also tested in 10 trials. The results obtained were as follows; 1. The general behavioral activity of d-amphetamine group was significantly greater than that of control, however, the chlorpromazine animals showed the tendency to decrease in activity. 2. The d-amphetamine group showed the occurence of orienting response to sound significantly more often than that of placebo controls. However, the chlorpromazine group exhibited significantly fewer orienting response than the placebo group did. 3. The d-amphetamine group displayed no clear out habituation to the orienting response following the repetition of trials, though the placebo and the chlorpromazine groups demonstrated apparent habituation to the response. 4. The three animal groups did not differ significantly from each other with regard to shift of attention from sound to light stimulus. It is inferred that the d-amphetamine tends to increase general activity has a definite facilitative action of orienting response and a inhibitory influence upon the habituation of the latter response. On the contrary, the chlorpromazine tends to decrease general activity, has a inhibitory action of orienting response and facilitatory action of habituation of the response.

  • Rutaecarpine is one of quinazolinocarboline alkaloids found in Evodia rutaecarpa, a Rutaceous plant and it has shown various biological effects including antiinflammation. However, the effect of rutaecarpine on nervous system was not reported yet. In this study we investigated the general pharmacology of rutaecalpine on the central nervous system. Rutaecapine (4O and 400 mg/kg) did not change chemoshock induced by pentylenetetrazole. However, oral administration of rutaecarpine altered motor coordination examined by rotarod test, pentobarbital-induced sleeping time and acetic acid-induced writhing syndrome in mice at the doses of 40 and 400 mg/kg. Rutaecarpine also induced hypothermia in mice at both doses. The results suggest that rutaecapine possesses neuromodulating activities on central nervous system in addition to the various biological effects on the Periphery.

  • General pharmacological properties of urinary trypsin inhibitor (UTI) following intravenous administration of 1,000,000 units/kg were examined in terms of effects on central nervous system, cardiovascular system, respiratory system, gastrointestinal system in mice, rats and rabbits. Administration of UTI (1,000,000 units/kg, iv) had no effect on central nervous system; no influences on pentobarbital sleeping time, spontaneous activity, normal body temperature, chemoshock produced by pentylenetetrazole solution, writhing syndromes induced by 0.6% acetic acid solution, and motor coordination of mice. The administration of UTI (1,000,000) units/kg, iv) in rats had no effect on systolic blood pressure and pulse rate. UTI (500,000 units/kg, iv) given to anesthetized rabbits showed no effect on respiratory rate. However, it showed significant elevation of respiratory rate at the concentration of 1,000,000 units/kg. Gastric secretion of rat and intestinal motility of mice were not influenced by the dose of 1,000,000 units/kg. In terms of autonomic nervous system, the material did not show direct effect and inhibitory or augmentative action of histamine- or acetylcholine-induced contraction at the concentration of 2,000 units/ml in the isolated ileum of guinea pig.

  • General pharmacological properties of AG 60 (mixture of acriflavine and guanosine (1:1, w/w)), which has anticancer effect, following intramuscular administration were examined in terms of effects on central nervous system, gastrointestinal system, cardiovascular system, respiratory system and autonomic nervous system in mice, rats, guinea-pigs and rabbits. AG 60 at the dose of 15 mgtg had no influences on pentobarbital sleeping time, spontaneous motor activity, chemoshock produced by pentylenetetrazole solution, writhing syndromes induced by 0.8% acetic acid solution, and motor coordination of mice. However, AG 60 at the dose of 7.5 and 15 mg/kg caused significant decrease of normal body temperature 1 and/or 2 h after the administration. No influence on body temperature was observed at 3.75 mg/kg in mice. Gastric secretion of rat and intestinal motility of mice were not influenced by the dose of 15 mg/kg. In terms of autonomic nervous system, AG 60 did not show direct effect and inhibitory or augmentative action of histamine- or acetylcholine-induced contractions at the concentration of 5 mg/L in the isolated ileum of guinea-pig. The administration of 15 mg/kg of AG 60 did not affect mean arterial blood pressure and heart rate in rat. AG 60 (15 mg/kg) given to anesthetized rabbits showed no effect on respiratory rate.

  • The aim of the present study is to investigate central nervous system (CNS) activity of the methanol extracts of leaves of Caesalpinia bonducella (MECB) and stem bark of Bauhinia racemosa (MEBR) (Caesalpinaceae) in Swiss albino mice and Wistar albino rats. General behavior, exploratory behavior, muscle relaxant activity and phenobarbitone sodium-induced sleeping time were studied. The results revealed that the methanol extracts of leaves of Caesalpinia bonducella at 100 - 200 mg/kg and stem bark of Bauhinia racemosa 100 - 200 mg/kg caused a significant reduction in the spontaneous activity (general behavioral profile), remarkable decrease in exploratory behavioral pattern (Y-maze and head dip test), a reduction in muscle relaxant activity (rotarod and traction tests), and also significantly potentiated phenobarbitone sodium-induced sleeping time. The results suggest that MECB and MEBR exhibit CNS depressant activity in tested animal models.

  • The general pharmacological tests with rhGM-CSF indicated that it had no influences on rotarod and locomotor activity tests, but shortened hexobarbital-sleeping time at the large dose of 3 mg/kg s.c. in mice. It elicited no hypothermic, analgesic and antiepileptic action. No influences on blood pressure and respiration in rabbits were observed at the dose of 1 mg/kg, i.v. and it did neither affect the receptors of adrenaline, acetylcholine, serotonin, histamine, kinin and oxytocin, nor antagonize the actions of histamine, serotonin and oxytocin at its concentrations of 1$\times$$10^{-6}$g/ml. However, this substance was demonstrated to stimulate the formation of leucocytes in rats.
