  • The local irritation studies of DA-3285, recombinant human erytropoietin(rHu-EPO), were carried out in rabbits after the following treatment; single application into the conjunctival sac of the eye, single subcutaneous injection, 7-day repeated subcutaneous injection and 8-day repeated infusion into the ear vein. Also, the local irritancy of DA-3285 leaked around vein was studied in mice by single perivascular injection. The results obtained were as follows. In the result of ocular irritation test, DA-3285 could be considered as a non-irritating material. In single and 7-day repeated subcutaneous irritation test, the irritancy of DA-3285 was not so much different from that of saline. The vascular irritancy of DA3285 by 8-day repeated infusion was negligible and similar to that of saline. And the irritancy of DA3285 by perivascular injection was comparable to that of saline. These results indicate that DA-3285 has no irritating activity when injected through subcutaneous or intravenous route for clinical practice as 3.5% solution.

  • 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.

  • The blood pressure response to Junci Herba water and methanol extracts in rabbit and $LD_{50}$ to Junci Herba water extract in mouse were investigated in order to develop a hypotensive agent from natural resources. $LD_{50}$ of Junci Herba water extract (WE) was 600 mg/kg in mouse, when WE was injected intraperitonealy. Junci Herba water and methanol extract, when injected into the vein of rabbit, produced a fall of blood pressure. Hypotensive effect of WE was suppressed by atropine and potentiated by phentolamine, while not affected by avil, propranolol, and phenoxybenzamine. Intravenous injection of chlorisondamine weakened the hypotensive effect of WE, and WE produced hypertensive effect in this rabbit. Intravenous injection of bretylium did not affect the hypotensive effect of WE, but WE produced hypertensive effect in this rabbit. In the rabbit treated with chlorisondamine, hypertensive effect of WE was suppressed by methysergide or bretylium, but not affected by atropine or phenoxybenzamine.

  • We recently developed a high efficiency expression vectors pCK, which drives a high level of gene expression in the skeletal muscles of mice. In this study, we investigated the pharmacokinetics and biodistribution of pCK-VEGF expressing human VEGF165 after intravenous or intramuscular administration. The quantity of pCK-VEGF in the tissues of mice was measured by the PCR method which has a detection limit of approximately 1 pg of the exogenously added plasmid. In the case of intravenous administration, the half life of the pCK-VEGF plasmid in the bloodstream was 1.68 min. After intra-muscular administration, the half life of pCK-VEGF plasmid in the bloodstream was 6.78 min. At 90 min post-administration, 30% of the injected pCK-VEGF was found at the site of injection, where it persisted for up to 8 hours. Less than 1.6% of the injected pCK-VEGF plasmid DNA was detected in highly vascularized tissues such as the lung, kidney; and liver at 90 min post-administration, but the plasmid was undetectable at later time points. These results suggested that intramuscularly administrated pCK-VEGF persisted for longer periods of time in muscles than in other tissues and that direct intra-muscular injection of pCK-VEGF might be useful for local therapeutic angiogenesis.

  • Flurbiprofen- and flurbiprofen axetil-loaded microemulsions composed of soybean oil, poloxamer 407, glycerine and water were prepared by generator-type homgenizer and ultrasoni c probe system. The particle size of microemulsions was measured by the dynamic light scattering method. The pharmacokinetics and organ distribution of flurbiprofen were investigated after intravenous injection of flurbiprofen solution, flurbiprofen-loaded microemulsion and flurbiprofen axetil-loaded microemulsions equivalent to 10mg/kg of flurbiprofen to rats. Blood samples were collected from the anterior ciliary artery of rats for 24hr, and flurbiprofen in plasma and organs was analyzed by HPLC. Stable microemulsions were prepared. Even though there is a little change in droplet size just after the preparation, no creaming and no separation were occured during the storage period for 6 months at 4, 21, 37 and 45$^{\circ}C$. Pharmacokinetic parameters and organ distribution of flurbiprofen after intravenous injection of flurbiprofen- and flurbiprofen axetil-loaded microemulsions emulsified with poloxamer 407 were not significantly different from those of commercial lipid microemulsion emulsified with lecithin. Therefore, it is concluded that flurbiprofen- and flurbiprofen axetil-loaded microemulsion prepared with poloxamer 407 could be used as a parenteral formulation.

  • Zinc oxide nanoparticles (ZnONPs) are widely used in a variety of products and cosmetic products including paper, paints, plastics and sunscreen. However, information on the safety of ZnONPs are not enough and many publications suggest possible toxic effects on environmental and human health. Furthermore, physico-chemical characteristics of nanoparticles makes it hard to test toxicity using the test guidelines of chemicals adopted by regulatory bodies. In this study, stability of ZnONPs was investigated using different types of isotonic solution, which is important in the toxicity study of intravenous route. Precipitation, aggregation, size, zeta potential and morphology of ZnONPs were evaluated with different times and concentrations. Precipitation of ZnONPs were observed in ionic isotonic solution including phosphate-buffered saline, Kreb's-Ringer solution, physiological salt solution and cell culture media of DMEM (Dulbecco's Modified Eagle's Medium) with 10% fetal bovine serum. On the other hand, they were stable without precipitation in non-ionic isotonic solution such as 5% glucose and 2% glycerol, respectively, which are biocompatible for intravenous injection. The average size of ZnONPs in 5% glucose and 2% glycerol was stably maintained, which is less than 30 nm and very similar as that in water dispersion of ZnONPs, provided by the manufacturer. The stability was maintained during the experimental period of 5 days and diluted state up to 15,000 ppm. These data suggest that 5% glucose and 2% glycerol solution can be used for the vehicles of ZnONPs in the toxicity study of intravenous injection route.

  • This study provides information for the design of pediatric inpatient uniforms with functionality and aesthetic beauty through a questionnaire-survey of the conditions of providing, wearing, preferences and improvement requirements for pediatric inpatient uniforms. As a result of the survey, intravenous injections were mostly given on the back of the hand, and the method of changing uniforms after intravenous injections was (in most cases) to pass the injection bottle through a sleeve or pant leg while the needle is inserted. The respondents answered that the sleeve length and pant length did not match. As a result of the preference of the pediatric inpatient design survey, respondents indicated they preferred pajama type, yellow color and medium size animal patterns. A similar ratio of set-in and raglan with no collar but with 3/4 length sleeve of round neck, front end, sleeve top opening, button closing and two pockets were preferred for shirts; however, a 3/4 length with rubber string on the waist, no opening and inner opening were preferred at the same ratio for pants. As for the method to adjust the length to assign functionality to pediatric inpatient uniforms, the most preferred sleeve was a roll-up sleeve with a strap and the most preferred pants were length adjusted pants that used a strap for both shirts and pants with a both sides strap. In addition, the majority of the respondents answered that a hand wrapper that protects the injection location during intravenous injections needs be developed. As for the development type, a half glove type and glove type were preferred in sequential order.
