  • The protective effect of sodium selenite($Na_2SeO_3$) against the cytogenetic toxicity of heavy metals was investigated on human whole-blood cultures in relation to induction of sister chromatid exchange (SCE) in secondary metaphase chromosome. Methylmercury chloride($CH_3HgCl$), cadmium chloride($CdCl_2$), potassium dichromate($K_2Cr_2O_7$), and sodium selenite caused to the typically dose-dependent increase in sister chromatid exchanges (SCEs) by the concentrations ranging from $0.3{\mu}M\;to\;10{mu}M$. However, the inductions of sister chromatid exchanges by methylmercury chloride or cadmium chloride were inhibited by the simultaneous addition of sodium selenite $1.2{mu}M$. The frequencies of SCE were decreased to the level of control in the molar ratios as 2:1, 1:1, 1:2, and 1:4 of selenium selenite vs. methylmercury chloride, and as 1:1 and 1:2 of selenium selenite vs. cadmium chloride, while the frequencies of SCE induced by potassium dichromate were not changed by the addition of sodium selenite in culture condition. Mitotic indices were decreased in the higher concentrations of chemicals and not significantly changed by the simultaneous addition of sodium selenite to the culture condition containing each chemicals.

  • In the study, we investigated the effect of Taurine-FTM, which is a commercially available fishery nutritional supplements complex, on anti-hepatotoxicity stressed with thioacetamide (TAA) and innate immune responses in olive flounder. To investigate the change in liver toxicity, firstly, TAA (30 ppm/100 g of fish) was intraperitoneally (i.p.) administered 12 hr after the intramuscular (i.m.) injection of Taurine-FTM (0.02 ml/100 g of fish)(Taurine/TAA). Secondly, Taurine-FTM was i.m. injected 24 hr after the administration of TAA (TAA/Taurine). Finally, TAA was administered simultaneously with Taurine-FTM (TAA+Taurine). All blood samples were collected 24 hr after injection. GOT level in group Taurine/TAA appeared similar to the control, whereas group TAA/Taurine and TAA+Taurine showed significantly increased (p<0.05) levels compared to the control. In GPT level, group Taurine/TAA and TAA/Taurine showed elevated levels compared to the control, whereas no significant difference was observed between group TAA+Taurine and the control. Serum ACH50 activity was significantly (p<0.05) augmented 24 hr after Taurine-FTM injection compared to the control group, whereas no significant increase was observed 48 hr after Taurine-FTM injection. On the other hand, serum lysozyme activity elevated in an acute stressed condition appeared significantly down-regulated 24 and 48 hr after Taurine-FTM injection compared to the control. In conclusion, i.m. injected Taurine-FTM augmented flounder serum complement activity and decreased a possible handling stress resulting in reducing a serum lysozyme activity and recovering hepatotoxicity. Thus, it is assumed that i.m. injection of Taurine-FTM mixed with antibiotics or available vaccines could be utilized as an anti-hepatotoxic recipe in fish culture industry.

  • We examined the wound healing effect and toxicity of Forsythia suspensa extract to verify the therapeutic usefulness on wound treatment. Additionally, we examined its antibacterial effect. The wound healing effect of Forsythia suspensa extract was compared with the tetrachlorodecaoxygen anion complex (TCDO), protein free haemodialysate (Haemyl), and physiological saline. The wound areas on the 4th, 11th, 14th day of treatment with Forsythia suspensa extract, TCDO, and Haemyl were significantly smaller than with the saline treatment. The wounds on the 8th day of treatment with Forsythia suspensa extract were only siginificantly smaller than the saline treatment. On the 8th day of treatment with Forsythia suspensa extract, TCDO, and Haemyl accerlerlated the wound epithelization more than saline treatment. There was not a significant difference in liver enzyme activity (GOT, GPT) and blood cell count between the Fosythia suspensa extract and the saline treatment. In addition, the Forsythia suspensa extract did not inhibit bacterial proliferation. These results suggest that Forsythia suspensa extract has great possibility of being developed into new wound healing drugs. Its pharmacological effects seem to have no relation with antibacterial effect.

  • Carbamazepine is a derivative of iminostilbene with carbamyl group and related chemically to the tricyclic antidepressants. Carbamazepine has been introduced for treatment of trigeminal neuralgia. Recently it is used as an antiepileptic agent such as diphenylhydantoin. Antiepileptic drugs are known to affect experimentally induced cardiac arrhythmia and are now widely used clinically for treatment of ventricular tachyarrhythmias, particularly those produced by digitalis intoxication. Steiner et al.(1970) reported that carbamazepine was found to be very effective in converting ventricular tachycardia due to digitalis toxicity to normal sinus rhythm. Clinically bradycardia, complete heart block, ventricular standstill and Adams-stokes attack were reported in the course of carbamazepine treatment. The purpose of this study was to investigate the effects of carbamazepine on the ouabain-induced arrhythmia in vivo. The rabbits of either sex, weighing from 1.6 to 3.2kg were anesthesized by urethane. After the trachea was cannulated, the rabbits were ventilated with room air using a respirator. Drugs were given into polyethylene cannula in the femoral vein. Blood pressure were recorded by physiograph via pressure tranducer connected with the cannula in the femoral artery. EKG were recorded by Physiograph via electrode implanted in both fore leg and left hind leg. The results are summarized as follows; 1. Arrhythmia was induced by continuous infusion of ouabain.($64{\pm}8.8{\mu}g/kg$) 2. Single administration of ouabain($64{\mu}g/kg$) induced arrhythmia which was persisted for 7-8 min. 3. Ouabain induced arrhythmia was restored to normal sinus rhythm by administration of carbamazepine.(The more dosage, the less frequent and the longer duration) 4. Severe bradycardia, A-V block, atrial fibrillation were seen on the EKG after injection of carbamazepine alone. By the above results, it may be concluded that carbamazepine inhibits the ouabain-induced arrhythmia by dose-dependent.

  • A novel screening strategy for salt-resistant antimicrobial peptides from a M13 peptide library was developed. Fusion of MSI-344, a magainin derivative and indolicidin to pIII coat proteins did not significantly affect viability of the recombinant phages, which indicated that the pIII could neutralize toxicity of the antimicrobial peptides and therefore it is possible to construct antimicrobial peptide library in Escherichia coli. On the basis of the conserved sequence of ${\alpha}$-helical antimicrobial peptides, a semi-combinatorial peptide library was constructed in which the peptides were displayed by pIII. To remove hemolytic activity from the library, the phages bound to red blood cells were removed, and the subtracted phage library was screened for binding to target bacteria Pseudomonas aeruginosa and Staphylococcus aureus under high salt concentrations. The screened peptides showed relatively low antimicrobial activity against the target bacteria. However, antimicrobial activities of the screened peptides P06 and S18 were not affected by the cation concentrations of 150 mM $Na^+$, 2 mM $Mg^{2+}$ and 2 mM $Ca^{2+}$ without significant hemolytic activity. This screening strategy that is based on binding capacity to target cells provides new potential to develop salt-tolerant antimicrobial peptides.

  • Objectives : The objective of this study is to evaluate the analgesic effects of Drosera rotundifolia L. pharmacopuncture on formalin-induced pain in Sprague-Dawley(SD) rats. Methods : In this experiment there were four groups, each with six SD rats. In the normal group (NOR), normal saline $40{\mu}L$ was injected at right KI3, and normal saline $40{\mu}L$ was injected at right hindpaw 35 minutes later. In the control group (CON), normal saline $40{\mu}L$ was injected at right KI3, and formalin 5 % $40{\mu}L$ was injected at right hindpaw 35 minutes later. In the Drosera rotundifolia L. pharmacopuncture 3 % group (DP3), Drosera rotundifolia L. pharmacopuncture 3 % $40{\mu}L$ was injected at right KI3, and formalin 5 % $40{\mu}L$ was injected at right hindpaw 35 minutes later. In the Drosera rotundifolia L. pharmacopuncture 5 % group (DP5), Drosera rotundifolia L. pharmacopuncture 5 % $40{\mu}L$ was injected at right KI3, and formalin 5 % $40{\mu}L$ was injected at right hindpaw 35 minutes later. We analyzed ultrasonic vocalization (USV), Substance P, aspartate aminotransferase(AST), and alanine aminotransferase(ALT). Results : In the early phase of USV, both DP3 and DP5 had an analgesic effect. In the late phase, DP5 had an analgesic effect compared to CON. Substance P in DP5 was significantly decreased compared to CON. In regards to blood AST and ALT, there was no significant difference among NOR, CON, DP3 or DP5. Conclusion : These results suggest that Drosera rotundifolia L. pharmacopuncture helps to reduce formalin-induced pain. It's mechanism is related to substance P, and Drosera rotundifolia L. pharmacopuncture has no influence on liver toxicity.

  • The experiments was undertaken to evaluate the effects of herbal medicine, Dalsaengtang, in pregnant rats and fetuses. Female Sprague-Dawley rats were orally administered with the Dalsaengtang at dose of 5 mg/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and observed internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Maternal body weight of dalsaengtang treated group has a tendency to increase compared to that of control group. The relative liver and kidney weights of dalsaengtang treated group were also increased to that of control group. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and implantation rate, delivery rate, late resorption rate and sex ratio. But Dalsaengtang administered group showed lower early resorption rate than the control group. From the sex ratio, number of females, bigger than number of males in the control group, and more males than females in Dalsaengtang administered group. Neonatal body weight and number of fetus of Dalsaengtang group were increased to that of control group. The fetuses of dams treated with Dalsaengtang didn't showed external malformation. Vertebral and sternal variations were observed in Dalsaengtang group but, compared to the control, those variations were insignificant. The number of ribs, cervical, thoracic, and lumber were normal. The number of sacral and caudal vertebrae were increased. Fetuses showed significant difference in the number of caudal vertebra (P<0.01). From these results, it can be concluded that Dalsaengtang showed no toxicity effects on maternal body weight, early resorption rate, and number of live fetuses. There were no significant changes in organ weight, hematological data, reproductive organs. Although skeletal variations were showed in vertebrate and sternum, Dalsaengtang did not shown significant changes in bone malformation.
