This study was conducted to determined if single subcutaneous (s.c.) injection of Folltropin-V dissolved in polyethyleneglycol (PEG) can replace as the standard multiple intramuscular (i.m.) injection. The results suggest that the s.c. treatment produced more corpora lutea, embryos recovered and transferable embryos as compared to the i.m. treatment (p<0.05). This study indicates that a single s.c. injection of Folltropin-V dissolved in PEG was effective for superovulatory response and embryo yield in Korean cattle.

The aim of this study is to evaluate the effects of vitamin or mineral supplements on the conception rates of dairy heifers when replacing the last injection of GnRH with hCG in ovsynch protocol (experiment 1) and also to investigate whether the estrus synchronization treatment in the heifer stage affects the conception rates after $1^{st}$ parturition (experiment 2). In experiment 1, 50 heifers were randomly assigned into 3 groups: 20 heifers each in groups 1 and 2, and 10 in group 3. All three groups were treated with an intramuscular injection of GnRH on day 0 (day 0 = the day of program start), $PGF_{2{\alpha}}$ on day 7 and hCG on day 9, and were inseminated on day 10, 12~16h after hCG injection. In group 1 (vitamin group), the heifers were treated with an intramuscular injection of 5 ml of vitamin-ADE $500^{(R)}$, and group 2 (mineral group) was treated twice with an intramuscular injection of 30 ml of mineral supplement-LAPTOVET$^{(R)}$ on a one-week interval beginning on the day of hormone treatment (day 0 and day 7 respectively). Group 3 (control) was treated only with hormones. Pregnancy diagnosis was performed by ultrasonography through a rectal probe. First service conception rates (FSCR) and average services per conception (ASPC) were recorded for all subjects. Of the total 50 heifers, 6 (2 in group 1, 3 in group 2, and 1 in group 3) heifers were eliminated due to accidents during experiment 1. FSCRs were 58.8% (10/17), 66.7% (12/18) and 44.4% (4/9) in groups 1, 2 and 3, respectively. ASPCs were $1.53{\pm}0.72$, $1.27{\pm}0.59$ and $1.63{\pm}0.74$ in groups 1, 2 and 3, respectively. Although there were no significant difference between the groups, relatively good results (higher FSCR and lower ASPC) were obtained in both group 1 and 2. In experiment 2, 11 primiparous cows from group 2 of experiment 1 in heifer stage which had been treated both with the hormones for estrus synchronizing and mineral supplements (ES group), and 12 primiparous cows treated only with minerals (non-ES group) were compared to examine the effects of estrus synchronization program on conception rates after $1^{st}$ parturition. Following the examination, postpartum ASPCs were $1.55{\pm}0.82$ and $2.17{\pm}1.47$ in ES group and non-ES group, respectively. The postpartum average days open (ADO) were $116{\pm}56$ and $197{\pm}93$ in ES group and non-ES group, respectively. Although there were no significant difference between the two groups, desirable results (lower ASPC and shorter ADO) were found in ES group after $1^{st}$ parturiton. In conclusion, experiment 1 indicates that vitamin or mineral supplement with ovsynch protocol may have some positive effect on FSCR and ASPC of dairy heifers, and in experiment 2, ES program in heifer stage had a positive effect on ASPC and ADO following $1^{st}$ parturition.

Background: Intrathecal injection of morphine is widely used in the management of postoperative pain because it provides long-lasting analgesia. Intramuscular caroverine and tiaprofenate are used to produce postoperative pain relief. This study was designed to evaluate the analgesic efficacy and quality of sleep achieved with intrathecal morphine and those of intramuscular caroverine and tiaprofenate in transurethral resection of the prostate (TURP). Methods: Forty patients undergoing elective TURP were randomly allocated into 2 groups as follows: Group M (n=20); 0.25 mg of morphine hydrochloride mixed in 7.5 mg of 0.5% hyperbaric bupivacaine was administered at the time of induction of spinal anesthesia. Group S (n=20); 7.5 mg of 0.5% hyperbaric bupivacaine was administered intrathecally and caroverine and tiaprofenate intramuscularly at every 8 hr and 12hr postoperatively for management of postoperative pain. We evaluated the analgesic efficacy with visual analog scale (VAS), quality of sleep, and side effects. Results: VAS at 6, 12 and 24 hours after operation were significantly less (p<0.01) in the group M than in the group S. Group M was superior to group S with respect to quality of sleep (p<0.01). In the group M, the incidence of nausea was 30% (6/20) and that of pruritus was 35% (7/20) and clinical respiratory depression did not occur. Conclusions: Intrathecal 0.25 mg morphine provides good postoperative analgesic effect. but intramuscular caroverine and tiaprofenate does not.

When tachyzoites (RH strain) of Toxoplasmo gondii are injected intramuscularly, experimental mice survive up to 7 days, 1-2 days longer than those infected intraperitoneally. We observed sequential histopathological changes in inguinal Iymph nodes after intramuscular injection of tachyzoites to thighs of specific pathogen free (SPF) mice. Initial findings on 1 or 3 days after the injection were reactive germinal centers, distended sinuses and epithelioid cell clusters in cortical and paracortical regions. Later on 5 days after the injection, however, effacement of nodal structure with depletion of cells and focal necrosis were observed . Necrotizing Iymphadenitis in the experimental murine toxoplasmosis suggests the causal relation between T. gondii infection and the human disease.

Background: Transdermal fentanyl patch (TDFP) is a simple, noninvasive analgesic with continuous effect. The aim of this study was to evaluate the postoperative analgesic effect of TDFP. Methods: Sixty healthy patients undergoing cesarean section were divided into 3 groups. Postoperative pain was controlled with different methods; Group I: application of TDFP-$25{\mu}g/hr$, Group II: intramuscular injection of ketoprofen; Group III: continuous epidural block. Pain scores (numerical rating scale, NRS), number of patients who needed additive ketoprofen injections and side effects were recorded at 8, 20, 32, 44 hours postoperatively. Results: There was no significanant difference in pain score between Group I and Group II. The numbers of patients who need additive ketoprofen injections were lower in group I than group II. Pruritis (25%), nausea/vomiting (10%), leg numbness (40%) was experienced in group III, but not in Group I & II. Conclusions: TDFP-$25{\mu}g/hr$ for postoperative pain control is simpler and more convinient than intramuscular injection of analgesics.

We established a new method to analyze abamectin using HPTLC (high performance thin layer chromatography) in order to obtain its pharmacokinetic profiles in pigs. Recovery of abamectin in pig serum after fluorescence derivatization was $80.01{\pm}3.82%$ at 0.1ppm and $83.67{\pm}3.63%$ at 10ppm, respectively. Detection reproducibility in terms of coefficient variation (c.v.) was 3.09% and 2.74% (intra-day), and 3.71% and 51.7%(inter-day), for 0.1 and 10ppm, respectively. Pharmacokinetics of abamectin was studied in five Yorkshire-Landrace mixed bred male pigs ($35.0{\pm}2.7kg$) administered intramuscularly 0.3mg/kg b.w. Pharmacokinetic profiles of abamectin in pigs were described by the 1-compartment open model with first-order absorption and first-order elimination. AUC (area under the curve) was $262.65{\pm}16.44ng{\cdot}day/ml$ and the biological elimination half-life ($t_{1/2},\;k_e$) was $5.28{\pm}0.84$ days, indicating somewhat high bioavailability and long half-life by the intramuscular route. We suggest intramucular injection of abamectin could be also used in place of the recommended route of its subcutaneous administration so far.

The author studied the effects of cyclophosphamide to the Dental pulps of Rabbits. Eighteen rabbits were used. The experimental rabbits were given an intramuscular injection of cyclophosphamide 50mg. per 1.5Kg. of body weight. In order to investigate effects of cyclophosphamide to the pulps of rabbits the control and experimental rabbits were sacrificed, on 1,3,5,7,10, and 14 days after injection of cyclophosphamide and made preparations for histopathologic findings. The results were as fallows. 1. In the early stage after injection of cyclophosphamide, retrcgrade degeneration of pulps such as infiltration of inflammatory cells, vacuolization, hyaline degeneration and reticular tissue atrophy in pulps were revealed. 2. The pulps were recovered from 10 to 14 days after injection of cyclophosphamide.

The pathogenecity of atypical Aeromonas salmonicida was studied in healthy Oreochromis niloticus. Inoculum at concentration of $1.5{\times}10^8CFU/ml$ and $3{\times}10^8CFU/ml$ was injected into healthy fish through intramuscular and intraperitoneal injections. Experimentally infected Oreochromis niloticus showed ulceration at the dorsal musculature and trunk region in addition to black coloration, congested gills, exophthalmia, and ocular hemorrhage. Congested liver and kidney were recorded in post-mortem examination. Mortality of the experimentally infected Oreochromis niloticus reached 100% after intramuscular injection at concentration of $3{\times}10^8CFU/ml$. Histopathological investigation of infected organs was also performed. There was a focal area of bundles of skeletal musculature showing hyalinization. In addition, hyperplasia, congestion, and fusion were noticed in the gill lamellae. There was also congestion in the blood vessels in the ocular chamber. Severe congestion was also noticed in the central vein of liver associated with focal aggregation of the melanin pigmented cells in the parenchyma. Degenerative changes were noticed in the epithelial cells lining of kidney tubules. Plant extracts carvacrol and its biological precursor cymene were found to be effective in treating experimentally infected Oreochromis niloticus at concentration of 100 or 200 ppm.

Background: Painful experiences during procedures such as prolotherapy and intramuscular stimulation are stressful to patients and can affect the treatment outcome. We present a method for relieving pain and increasing the level of patient comfort during the procedure. Methods: Twenty six patients who requested sedation anesthesia during the procedure were examined. All patients were injected with 500 ml of 0.9% normal saline and were monitored by electrocardiography, blood pressure and pulse oximetry. The patients were supplied with oxygen (3 L/min) through a nasal cannula. Midazolam (0.02 mg/kg) and alfentanil ($8{\mu}g/kg$) was injected before the procedure and a bolus injection was administered during the procedure if patients felt any pain. The duration of the procedure, the total amount of drugs, the changes in the systolic blood pressure, heart rate, pulse oxygen saturation, sedation and pain level during procedure, satisfaction scale after the procedure, complications and the incidence of amnesia were evaluated. Results: Twenty one patients had a moderate level of sedation, 15 patients did not feel any pain during the procedure, 17 patients had high level of satisfaction (8-10). No patient experienced complications after the procedure, or unstable vital signs, and 6 patients could not remember the procedure. Conclusions: Sedation anesthesia is a safe method for relieving pain during the procedure, and most patients had a high level of satisfaction.
