  • The effects of dietary $\beta$-glucan administration on non-specific immune parameters in common carp, Cyprinus carpio, (1.0 g and 68.7 g of body weight) and flounder, Paralichthys olivcaces (12.1 g and 54.0 g of body weight) were evaluated. All fishes were fed an experimental diet supplemented with $\beta$-glucan at $0.1\%$ per kg diet for 5 weeks. A week intermission with basal diet occurred between first 2 weeks and second 2 weeks of $\beta$-glucan administration, The changes in the numbers of peripheral neutrophils and macrophages were counted under light microscopy and serum lysozyme activity was also analysed at a week of interval during the experiment. Phagocytic activities of leucocytes from the swimm bladder of carp and the peritonium of flounder were measured 5 weeks after feeding. The oral adminisration of $\beta$-glucan induced significant reduction in mortality after an artificial challenge with $1\times10^6$ cells of Aeromonas hydrophila in larger carp and $1\times10^5$ cells of Edwardsiella tarda in larger flounder but did not in other groups. The numbers of peripheral macrophages and neutrophils, phagocytic acitivies of leucocytes, and the activity of serum lysozyme were greatly increased in the fish fed a $\beta$-glucan supplemented diet. These suggest that $\beta$-glucan administration by oral route can enhance leucocyte phagocytic activity, serum lysozymal activity, and survival rate against artificial infections depending on the infected fish size and challenged bacterial concentration.

  • The purpose of present study was to compare the sedative effect of intranasal and oral midazolam treatment. The study was conducted on twenty eight child patients who required at least two visits. All the patients showed a good physical status (ASA-I). The patient was randomly assigned to receive midazolam either intranasal (Group I, 0.25 mg/kg) or oral (Group II, 0.5mg/kg) route at each visit. Treatment procedure was divided into six stages. In each stage, sleep score, crying score, movement score and overall behavior score were evaluated. The overall results can be summarized as follows: 1. Through all treatment procedures, no significant difference was observed between Group I and Group II in terms of sleep, crying, movement and overall behavior index. 2. In a questionnaire to the parents, 67.8% of parents answered that the child suffered at intranasal administration, while only 17.7% of parents responded the same way at oral administration. 3. In a questionnaire regarding patients' behavior at home after midazolam treatment, 'Similar to normal behavior' was 78.6% in Group I and 57.1% in Group II, indicating that intranasal treatment of midazolam may be more effective for the recovery.

  • The experimental study was undertaken to confirm the effect of vaccination of birds with Newcastle disease (ND) vaccines on the Market by use of th. various vaccination programs. Sixteen groups of birds varying from 2 to f days of age, which were originated from hyper-immunised hens against ND were immunised by three different ways, a live vaccine only, a killed vaccine only, and the combination of a live and killed vaccine according to the each schedule of employed programs. In the administration of a live vaccine only, birds were immunized by one of following methods, the combination of intranasal and intraocular inoculation, intramuscular inoculation, via drinking water and the double inoculation by spray and drinking water application. Except for the double application, all the birds were vaccinated 2,3 or 4 times with two volumes of the virus dose (drinking water application) instructed by the commercial vaccine laboratory, until 21, 28 or 30 days of age, and all the immunized birds 19, 21 or 28 days postvaccination were challenged intramuscularly with 1.0$m\ell$ of 10,000 MLD per $m\ell$ of a virulent ND virus. In the administration of the combination of a live and killed vaccine, birds were immunized 2 or 3 times intranasally at first until 14 or 28 days of age with the same dose of the above experiment of a live vaccine, and then inoculated intramuscularly 1 or 2 times until 60 days of age with 1.0 $m\ell$ of a killed vaccine. And all immunized birds 11 days postvaccination were challenged with the same procedure of the above experiment. In the administration of a killed vaccine only, birds were immunized 3 times intramuscularly until 28 days of age with varied dose (0.2-0.5 $m\ell$) of a killed vaccine and all immunized birds 33 days postvaccination were challenged with the same procedure of the above experiment. The results obtained are summerised as follows: All birds vaccinated by using the combination of a live and killed vaccine program or a killed vaccin only appeared to be refractory. without any sign of illness, to the challenge exposure with 1.0$m\ell$ of 10,000 MLD per $m\ell$ of a virulent ND virus. On the other hand, the survival rates of birds of live vaccine groups immunized by a number of vaccine program such as Salsbury's day old program, 3-3-3 program, the Institute of Veterinary Reserch program and Multiple inoculation program, were 39.58%, 43.7%, 43.75% and 47.80%, respectively. And the survival rates of birds vaccinated with a live vaccine by 4 different ways of administration, i.e., double inoculation by water and aerosol application, intramuscular injection, intranasal instillation and via 4.inking water were 87.50%, 64.06%, 42.18% and 25.00%, respectively.

  • The distribution, metabolism and excretion of CKD-602{20(S)-7-[2-(N-Isopropylamino)ethyl]camptothecin HCI), a new camptothecin derivative, were investigated in rats after a sing le administration of CKD-602. 1. The tissue levels of CKD-602 given to mice by the intravenous route at a dose of 20mg/kg were the highest in intestine, followed in descending order by kidney, liver, stomach,lung, heart, spleen and plasma. The concentrations of CKD-602 after 24hrs decreased to less than 2% of the peak level in most tissues except the skin. The urinary and fecal excretion of CKD-602 were 47.6% and 44.4% of the administered dose, respectively, with 0.7% remaining in the rinse. 2. After administration of CKD-602 at 10mg/kg in rats, metabolism of this compound was examined in plasma, urine, and feces. The plasma samples were collected for 24hr, urinary and fecal samples for 72hr. While any peak of CKD-602 in HPLC chromatograms was not detected from plasma and urine it was detected in feces (peaks, 9.8 min). However, additional peak area was about 0.5% of the peak area of parent CKD-602. Therefore, CKD-602 may be eliminated with the parent form and rarely metabolized in the body. 4. After I.v. administration of CKD-602 at 10mg/kg in rats, urinary and fecal excretions were examined for 72hrs post dose period. 87% of total urinary excretion of CKD-602 was excreted within 8hr after administration, 53%, and 32% of total fecal excreted amounts were determined in 0-24 hr and 24-48hr periods, respectively. The total excretion amounts of CKD-602 into urine and feces were 94% of the administered dose.

  • The specific antibody response of olive flounder, Paralichthys olivaceus to change in rearing-environmental conditions post immunization with antigen (bovine serum albumin, BSA) and different routes of antigen administration were investigated by enzyme-linked immunosorbent assay (ELISA). To test the effect of routes of antigen administration, flounder were injected intraperioneally or intramuscularlly with 1 mg of BSA. In addition, to test the effect of change in environmental condition post immunization, flounder were injected intraperioneally with 1 mg of antigen, and then were exposed to acute thermal change (the water temperature (WT) was decreased from $21^{\circ}C$ to $15^{\circ}C$ within 30 min and maintained at $15^{\circ}C$ for 3 h), handling (fish were caught and subsequently held out of water for 1 min) or heavy oil (76 g/200 L for 2 days). Consequently, there was no significant difference between intraperioneal (IP) and intramuscular (IM) injections except at 10 days post-immunization. With these results, it suggests that both 1M and IP injections may be used as route of vaccination. Furthermore, no significant difference was observed in the antibody response among the groups exposed to heavy oil, handling, sudden drop of WT and positive control except at 10 days post-immunization. From these results, it was confirmed that specific antibody response was not affected by the above mentioned rearing-environmental conditions, suggesting that vaccination can be employed at changing rearing-environmental conditions.

  • Single and 4 weeks oral administration of New wonbangwoohwangchungsimwon (NSCH) which was used l-muscone as substitutive material qf musk, to beagle dogs of both sexes were per-formed to investigate both acute and subacute toxicity. Beagle dogs (3 males and 3 females) in acute experiments were administered orally with single dose of 2,000 mg/kg and groups of 9 male and 9 female beagle dogs in subacute experiments were given daily different dosage of NSCH, 160 mg/kg/day (low dosage group), 400 mg/kg/day (middle dosage group), 1,000 mg/kg/day (high dosage group) once a day for 4 weeks by oral route according to the Established Regulation of Korea Food and Drug Ad-ministration (l996. 4. 16). $LD_{50}$ value for beagle dogs was more than 2,000 mg/kg per oral for both male and females. In animals administered with NSCH, there were neither dead animals nor significant changes of body weights. In addition, no differences were found between control and treated groups in clinical sign, urinalysis, eye examination, hematology, serum chemistry, organ weight and other fingings. No histological lesions were observed in both control and treatment groups. Above data strongly suggset that NSCH in beagle dogs is considered to be safe.

  • As a series of safety studies of DA-3030, a new rhO-CSF, its local irritancy was examined in the rabbits after the following treatment; application into the conjunctival sac of the eye(single), subcutaneous injection(single), intramuscular injection(single), and intravenous injection(8-day repeated). In addition, paravenous irritation of DA-3030 was investigated in mice. The results obtained were as follows. 1. In the result of ocular irritation test, 0.03% solution of DA-3030 could be considered as a non-irritating material. 2. The local irritation of DA-3030 by an injection of 0.5mι of its solution subcutaneously or intramuscularly was negligible and not so much different from that of saline. 3. In the vascular irritancy test, macro- and microscopic observations revealed that the irritating activity of DA-3030 in blood vessels was not different from that of saline when they were injected once a day into vein retroauricularis of rabbits for 8 days.4. The paravenous administration of DA-3030 did not induce any abnormal changes at injection sites except mild swelling in 1 mouse at 3 hours after injection which was thought to be due to slow absorption. The above-mentioned results suggest that DA-3030 has no irritating activity when injected through intravenous or subcutaneous route for clinical practice as 0.03% solution.

  • Poly(acrylic acid) (PAA) was identified to possess good mucoadhesive properties ensuring its application to extend the retention times of the formulations at the oral cavity, intended route of administration using the polymer. In the noncross-linked state, PAA will swell and become eroded owing to the presence of salivary flow from the site of application. The formation of cross-links between the polymer chains will allow swelling but prevents the erosion of the dosage form. In the current study, cross-linking was achieved by esterification of the PAA chains with sucrose. The density of crosslinking was modified by changing sucrose concentration and the duration of cure time. The cross-linking density of the polymer hydrogel was assessed by equilibrium swelling studies. The mucoadhesion testing method allowed a comparative study of the hydrogels prepared. An inverse relationship between equilibrium swelling and peak detachment force showed that increased PAA chain density per unit area enhanced the mucoadhesive interaction.
