  • The cortex and root of Acnthopanax sessiliflorus, a herbal medicine, have been used for several diseases including cancer in Oriental countries. In the previous study, we showed that the cortex of this plant have anti-cancer activity. But its therapeutic efficacy of CORTEX ACANTHOPANAX RADICIS (CAR) is not clarified. For these reasons, we investigated immuno-potentiating and anti-cancer properties of CAR compared with CA, in terms of body and tumor weights, proliferation of thymocytes and tumor cells, and nitric oxide production from macrophages through in vitro and in vivo studies. In our results, administration of CAR reduced tumor mass and increased body weights. CAR also inhibited proliferation of tumor cells in vivo and in vitro dose-dependently. Thymocyte proliferation was accelerated by treatment with CAR and NO production was also promoted by CAR in vivo and vitro. In conclusion, we demonstrated that CAR is useful to treat for cancer as complementary or alternative medicine to Western medication, its therapeutic efficacy is involved in direct inhibition of tumor growth and immuno-potentiating activity.

  • Background: Florfenicol might be ineffective for treating Staphylococcus aureus small colony variants (SCVs) mastitis. Objectives: In this study, florfenicol-loaded chitosan (CS)-sodium tripolyphosphate (TPP) composite nanogels were prepared to allow targeted delivery to SCV infected sites. Methods: The formulation screening, the characteristics, in vitro release, antibacterial activity, therapeutic efficacy, and biosafety of the florfenicol composite nanogels were studied. Results: The optimized formulation was obtained when the CS and TPP were 10 and 5 mg/mL, respectively. The encapsulation efficiency, loading capacity, size, polydispersity index, and zeta potential of the optimized florfenicol composite nanogels were 87.3% ± 2.7%, 5.8% ± 1.4%, 280.3 ± 1.5 nm, 0.15 ± 0.03, and 36.3 ± 1.4 mv, respectively. Optical and scanning electron microscopy showed that spherical particles with a relatively uniform distribution and drugs might be incorporated in cross-linked polymeric networks. The in vitro release study showed that the florfenicol composite nanogels exhibited a biphasic pattern with the sustained release of 72.2% ± 1.8% at 48 h in pH 5.5 phosphate-buffered saline. The minimal inhibitory concentrations of commercial florfenicol solution and florfenicol composite nanogels against SCVs were 1 and 0.25 ㎍/mL, respectively. The time-killing curves and live-dead bacterial staining showed that the florfenicol composite nanogels were concentration-dependent. Furthermore, the florfenicol composite nanogels displayed good therapeutic efficacy against SCVs mastitis. Biological safety studies showed that the florfenicol composite nanogels might be a biocompatible preparation because of their non-toxic effects on the renal tissue and liver. Conclusions: Florfenicol composite nanogels might improve the treatment of SCV infections.

  • Purpose : Ascending cholangitis is the most common complication after Kasai operations. The aim of this study is to evaluate the therapeutic efficacy of cefotaxime as an empirical antibiotic on ascending cholangitis after Kasai operations. Methods : Thirty-nine episodes of cholangitis in twenty-nine children who underwent Kasai operations at Seoul National University Children's Hospital from January 1991 to December 2000 were included in this study. Empirical cefotaxime treatments were divided into three groups : cefotaxime and amikacin treatment group(CA group), cefotaxime and gentamicin treatment group(CG group) and cefotaxime treatment group(C group). A diagnosis of cholangitis was made on the basis of unexplained fever(>$38^{\circ}C$) and either development of acholic stool or elevation of serum total bilirubin (>1.5 mg/dL). Therapeutic efficacy was judged by elimination of fever up to 72 hours, 120 hours, and 168 hours after antibiotic treatment. Results : There were therapeutic responses in 51%(20/39) up to 72 hours after antibiotic treatment : 54%(13/24) in CA group, 43%(3/7) in CG group and 50%(4/8) in C group. There were therapeutic responses in 69%(27/39) up to 120 hours, in 79%(31/39) up to 168 hours and in 82%(32/39) up to 2 weeks. There were no differences in therapeutic efficacy among the three regimens. In 12 of 39 episodes, the etiologic pathogens including Escherichia coli and enterococcus were cultured from the blood. Conclusion : Cefotaxime can be tried as an initial antibiotic in Korean children with ascending cholangitis after Kasai operation prior to the identification of microorganism on culture. However, further evaluation of pathogen and its resistant strain to cefotaxime should be done.

  • The study was clinically performed in the 65 outpatients with pruritus who visited the Dept. of Dermatology, Oriental Medicial Hospital, Kyung Hee University and oriental medical clinic of Hang Ki Park from Jan. 1985 through Dec. 1986. The results were summarized as follows: 1. Among 65 outpatients, male was 20 ($30.8\%$) and female was 45 ($69.2\%$). In the distribution of age, 10S was $21.5\%,\;and\;20S\;20\%$ at the first visit. 2. In the distribution of season, the peak incidence occured in Spring ($35.4\%$) and next incidence in Winter ($20\%$). 3. In the distribution of duration, $41.5\%$ was between 1 year and 5 years, $20\%$ between 1 month and 6 months, $12.3\%$ between 6 months and 1 year, $9.2\%$ between 5 years and 10 years, $7.7\%$ over 10 years. 4. In regard to the itching lesion, $66.2\%$ showed pruritus throughout the whole body, including partially $15.4\%$ in their heads and faces, $12.3\%$ in their hands and legs, and $6.3\%$ in their shoulders, sides and hips. 5. The most frequently used prescription, was Gosanhomasan (苦蔘胡麻散) which occupied $60.7\%$ of all, in next order of frequency, Gamisamooltang (加味四物湯 $21.4\%$) Gupoongchongkisan (祛風淸肌散 $12.5\%$) and Bangpoongtongsungsan (防風通聖散 $5.4\%$). 6. In regard to the therapeutic duration, $46.2\%$ was showed under 10 days, $18.5\%$ between 10 days and 20 days, and $16.9\%$ between 30 days and 60 days. 7. In the 35 patients, who were confirmed to show apparent result by continual treatment, curative rate was more than $57.6\%$. According to above results, we can confirm that efficacy of therapeutic measures by the oriental medicine on pruritic dermatoses was increased in proportion to therapeutic duration and we feel sure that the therapeutic efficacy can be gradually increased as we expect to make a deep study of the disease and to give correct medical treatment to the nature of the disease.

  • Background and Objectives The early assessment of treatment is not done for benign paroxysmal positional vertigo (BPPV) since the well-known phenomenon of fatigability after a repeated positional test can mimic successful treatment. The aim of this study is to evaluate the clinical implication of 'fatigability' after Epley maneuver and to identify the therapeutic efficacy of Epley maneuver in posterior canal BPPV (PC-BPPV). Subjects and Method This study was prospectively conducted by two dizziness clinics on 51 consecutive patients diagnosed with PC-BPPV. All patients included in the study received Epley maneuver treatment. The therapeutic results were reassessed immediately after a single trial of Epley maneuver. After 30 minutes, results were reassessed repeatedly to confirm the fatigability of diagnostic procedure immediately after treatment. If the treatment was not successful after 30 minutes, Epley maneuver was repeatedly performed until complete resolution. Results Immediately after the first maneuver, 45 of 51 (88.2%) patients had neither vertigo nor nystagmus during the positional test. All patients demonstrated complete resolution after receiving one to three Epley maneuvers on the day of diagnosis. 'Fatigability (false negative result)' was confirmed for only one case (1 of 6 patients, 16.7%), in which nystagmus was observed after 30 minutes but not identified immediately after the first Epley maneuver. Conclusion The therapeutic efficacy of Epley maneuver is very high in PC-BPPV. Considering the possibility of fatigability when reassessment is performed immediately after therapeutic maneuver, clinicians should avoid assessing the outcome immediately after treatment in patients with PC-BPPV.

  • This study was performed to assess the efficacy of Kinesiotape for the frozen shoulder patients. The subjects of this study were 17 patients with frozen shoulder who visited the out-patient department of the physical therapy, Pyongchon Sacret Heart Hospital, Hallim University, from July. 3, 2000 through August 12, 2000. To find out the effect of kinesiotape therapy, we sampled 8 patients treated with electrotherapy and therapeutic exercise (control group), and 9 patients treated with electrotherapy and therapeutic exercise with kinesiotape(experimental group). All patients were treated 3 days a week for 5 weeks. The results after 5-week treatment, compared with before treatment, were as follows: 1. The increase in range of motion in the electrotherapy and therapeutic exercise with kinesiotape after 5-week treatment was very significant(p<0.01). 2 The increase in range of motion in the electrotherapy and therapeutic exercise after 5-week treatment was significant (p<0.05). 3. The pain of decrease in the electrotherapy and therapeutic exercise with kinesiotape after 5-week treatment was very significant (p<0.01). 4. The pain of decrease in the electrotherapy and therapeutic exercise with kinesiotape 5-week treatment was significant(p<0.05). 5. The electrotherapy and therapeutic exercise with kinesiotape was more effective in increasing the range of motion on shoulder than the electrotherapy and therapeutic exercise after 5-week treatment(p<0.01). 6. The pain of decrease in between electrotherapy. therapeutic exercise with kinesiotape electrotherapy and therapeutic exercise after 5-week treatment was no significant.

  • This study evaluated the pharmacokinetic profile and therapeutic efficacy of piroxicam (PX), a long acting non-steroidal anti-inflammatory drug for the treatment of arthritis, following intra-articular (IA) injection in comparison to the pharmacokinetic profile and therapeutic efficacy of PX after intramuscular (IM) injection. In the pharmacokinetic study in rats, systemic exposure and pharmacokinetic parameters of PX after a single IA dose were compared with systemic exposure and pharmacokinetic parameters of PX after administration of the same dose IM (0.6 mg/kg). The anti-inflammatory and analgesic effects of IA PX were evaluated simultaneously in a monoiodoacetate-induced osteoarthritis rat model. The plasma PX concentration rapidly rose following IA injection, and it was comparable to the plasma PX concentration following IM injection, suggesting the rapid efflux of the drug molecule from the joint cavity. However, in the efficacy study, the IA PX administration significantly reduced the knee swelling by reducing the level of prostaglandin $E_2$ in the joint, compared to that following administration of IA vehicle and after administration of the IM PX dose. In addition, we found that the anti-inflammatory and anti-nociceptive efficacies of IA PX were synergistically increased upon co-treatment with hyaluronic acid (HA), a potent agent for the treatment of osteoarthritis, at the weight ratio of 1:1 or 1:2, and these effects were more pronounced than those following administration of HA or PX alone. In conclusion, this study demonstrated the efficacy of the IA use of PX alone and/or in combination with HA in osteoarthritis.

  • Parkinson's disease is a neurodegenerative disease caused by damage to brain neurons related to dopamine. Non-clinical animal models mainly used in Parkinson's disease research include drug-induced models of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and 6-hydroxydopamine, and genetically modified transgenic animal models. Parkinson's diagnosis can be made using brain imaging of the substantia nigra-striatal dopamine system and using a radiotracer that specifically binds to the dopamine transporter. In this study, 18F-N-(3-fluoropropyl)-2β-carboxymethoxy-3β-(4-iodophenyl) nortropane was used to confirm the image evaluation cutoff between normal and parkinson's disease models, and to confirm model persistence over time. In addition, the efficacy of single or combined administration of clinically used therapeutic drugs in parkinson's animal models was evaluated. Image analysis was performed using the PMOD software. Converted to standardized uptake value, and analyzed by standardized uptake value ratio by dividing the average value of left striatum by the average value of right striatum obtained by applying positron emission tomography images to the atlas magnetic resonance template. The image cutoff of the normal and the parkinson's disease model was calculated as SUVR=0.829, and it was confirmed that it was maintained during the test period. In the three-drug combination administration group, the right and left striatum showed a high symmetry of more than 0.942 on average and recovered significantly. Images using 18F-N-(3-fluoropropyl)-2β-carboxymethoxy-3β-(4-iodophenyl) nortropane are thought to be able to diagnose and evaluate treatment efficacy of non-clinical Parkinson's disease.

  • This study was conducted to explore the efficacy of bee venom as a treatment for mastitis and to determine the optimal dosage and treatment period. When 6 mg or 12 mg of bee venom was administered to each experimental quarter of mastitis in dairy cow, the clinical symptoms in the 12 mg quarter were noticeably improved compared to those in the 6 mg quarter. There was no significant difference in the somatic cell count (SCC) in the milk between normal and mastitis quarters between the 6 and 12 mg doses, but there was a steady decrease in the 12 mg-treated quarter (p = 0.34). To determine the treatment period, bee venom was administered for 2, 4, and 7 days. After administering 12 mg of bee venom for 7 days, the SCC in the milk was compared before 6 days and after 7 days, and the SCC was significantly decreased to less than 100,000 SC/mL after 7 days (p = 0.01). In addition, to investigate the efficacy of bee venom, the minimum inhibitory concentration for S. aureus, E. coli, and coagulase negative staphylococci was measured, and the results showed that Gram-positive bacteria were more sensitive to bee venom than Gram-negative bacteria, and treatment for Gram-negative bacteria was limited. As a result of this study, it was confirmed that a dose of 12 mg of bee venom and a treatment period of more than 7 days were required to treat mastitis, and that treatment with bee venom alone against Gram-negative bacteria was negative.

  • In a previous study we generated an anti-Hepatitis B Virus (HBV) preS1 humanized antibody (HzKR127) that showed in vivo HBV-neutralizing activity in chimpanzees. However, the antigen-binding affinity of the humanized antibody may not be sufficient for clinical use and thus affinity maturation is required for better therapeutic efficacy. In this study, phage display technique was employed to increase the affinity of HzKR127. All six amino acid residues (Glu95-Tyr96-Asp97-Glu98-Ala99-Tyr100) in the heavy (H) chain complementary-determining region 3 (HCDR3) of HzKR127 were randomized and phage-displayed single chain Fv (scFv) library was constructed. After three rounds of panning, 12 different clones exhibiting higher antigen-binding activity than the wild type ScFv were selected and their antigen-binding specificity for the preS1 confirmed. Subsequently, five ScFv clones were converted to whole IgG and subjected to affinity determination. The results showed that two clones (B3 and A19) exhibited an approximately 6 fold higher affinities than that of HzKR127. The affinity-matured humanized antibodies may be useful in anti-HBV immunotherapy.
