  • The effect of dietary pectin in the upper gastrointestinal transit rate was studied. Rats fed fiber-free diet or 10% pectin diet were offered 51-$CrCl_3,$ a transit marker. The movement of 51-Cr dose through the gastrointestinal tract was measured at intervals from 20 minutes to 6 hours after dosing. pectin significantly increased gastric emptying rate upto 3 hours after dosing. Pectin also increased small intestinal transit rate from 3 hours to 4 hours after dosing. The results suggest that delayed gastric emptying is not likely the important aspect of the mechanism by which pectin could flatten the post-prandial response of serum glucose and insulin.

  • The phannacokinetics and tissue distribution of DWQ-013, a new quinolone, were examined in rats and mice following a single intravenous and oral administration. DWQ-013 in plasma and urine was determined by both HPLC and microbiological assay. The plasma concentration of the drug declined biexponentially. The terminal half life of the drug was 11.11$\pm$0.14 hour after intravenous dosing. The volume of distribution at terminal elimination phase(Vd$_\beta$) and total clearance of the drug were 1.29$\pm$0.15 l/kg and 0.78$\pm$0.09 l/h/kg. The bioavailability of DWQ-013 after oral administration was 56.0% (HPLC) and 77.2%(bioassay), respectively. Twelve-hour urinary recovery of drug was measured by HPLC and bioassay to 0.035$\pm$0009% and 4.71$\pm$066% after oral dosing, to 0.055$\pm$0.014% and 7.65$\pm$1.53% after intravenous dosing, which may indicate the presence of biologically active metabolites. Binding of the drug to plasma proteins ranged from 97%~99% at various concentrations. The drug was highly distributed in order of liver, kidney and lung after 1.5 hours in mice.

  • The increased embryotoxicity of the antifolate drug pyrimethamine (PYM) with concomitant dietary dosing of folic acid (FA) was examined in mice. The preventive effects of folinic acid (FNA) on PYM embryotoxicity were also examined. Six groups were constructed: PYM I (pyrimethamine 80 ppm), PYM II (pyrimethamine 150 ppm), PYM II+FNA (pyrimethamine 150 ppm and folinic acid 12 mg/kg/day), PYM II+FA (pyrimethamine 150 ppm and folic acid 350 ppm), FA (folic acid 350 ppm) and a control group. The agents were administered for 7 days from day 6 throughout 12 of gestation. PYM and FA were administered with mashed feed and FNA was intraperitoneally injected. The high incidence of fetal realformations was observed in the PYM II group; these included kinky tail, open eyelids, club foot, cleft palate, absence of the pulmonary lobe, diaphragmatic hernia, fused sternebrae, fused cervical or thoracic vertebral arch, among others. All embryos of the PYM II+FA group were resorbed. No realformed fetuses were observed in the PYM II+FNA group. These results show that the concomitant dosing of FA augments PYM embryotoxicity. The preventive effects of FNA were also observed.

  • This study was carried out to investigate fatty liver in Korean black goats. Adult female goats were divided into 3 test groups(A, B and C). Group A and B of goats each received 3 test consecutive daily doses of DL-ethionine at 75mg/kg and 150mg/kg body weight, respectively. Group C of goats was given 3 consecutive doses of the compound every 48 hours at 150mg/kg body weight. The clinical symptoms, hematological values, serum chemical values and histopathological study of the liver were investigated in the test animals. The results obtained are as follows ; 1. Fatty liver were observed in every test animal. 2. Some clinical symptoms( anorexia, depression) were appeared from 1st day to 7th day after administration of the compound in every test animal. In addition to these symptoms, diarrhea and salivation were generally observed in test animals which were given the compound at 150mg/kg body weight. The degree of these symptoms was dose dependent. 3. There was no significant variations in total WBC counts and fibrinogen values in the blood of test goats. The PCV values were significantly increased on 5th day of dosing in group A and B of goats. 4. The total lipid value was not changed but the concentration of NEFA was significantly increased on 3rd day of dosing with the compound and returned to normal value after 10 days hereafter. The value of triglycerides was significantly increased on 1st day and returned to normal value on 3rd day of dosing. The value of cholesterol was significantly decreased on 3rd day and returned to normal value on 10th day after treatment. 5. Total protein level was decreased on 10th day of dosing in the groups of B and C, and billirubin level was significantly increased on 7th day of dosing in every test group and returned to normal level after 13th day of administration. 6. The activity of GGT in serum was not changed while the activities of SDH and AST were significantly increased in every test goat and those values were returned to normal after 10~13th day of trestment. 7 The 35K-protein fraction in serum was not detected by SDS-polyacrylamide gel electrophoresis, but this protein fraction was detected by the same method after treating the 21st and 22nd fraction which were obtained by column chromatography with Sephadex G-100. 8. The affected liver was congested and swollen on 3rd day, and yellowish brown in color and mottled appearance on 7th day of treatment. Histopathologically, fat droplets were common in the hepatocytes, this change was intensive on 7th day after treatment in group B and C. Hepatic cell necrosis was observed in some livers but this pathological change was disappeared and returned to normal after 13 days of treatment.

  • The acute oral toxicity of organogermanium, Ge-132 was evaluated in rats andmice. The changes of body weight and clinical signs were observed for 14 days after the oral administration of Ge-132, from 0.31 g/kg up to 5 g/kg for SD rats and from 1.25 g/kg up to 5 g/kg for ICR mice. No death and toxic effects were observed for 14 days. The body weight of rats was significantly decreased 1 day after the administration in the maximum dosing group, but the decrease of body weight returned to control level 3 days after dosing. No significant changes in 132. Therefore, Ge-132 has no special toxic effects up to 5 g/kg, and LD* values of Ge-132 Ge-132 are above 5 g/kg in rats and mice.

  • This experiment was undertaken in order to investigate whether chicken can serve as a carrier for swine lungworm, Metastrongylus apri. The results abtained are summerized as follows: All chickens which were fed the infective larvae of M. apri, in the form of infected earthworm (Eisenia foctida) excreted appreximately 4.4 to 5.4 percent of the infective larvae in their feces between 2 to 10 hours after dosing. The larval excretion was marked especially during the first 2 hours. A few (0.10~0.12%) larvae were detected from the intestinal wall of chickens by pepsin-digestion method on a day after dosing, but no further migration or development of the larvae was observed. The larvae which had passed through the digestive tract of chickens retained their viability and produced characteristic lungworm disease when inoculated to guineapigs. From these results, it may he concluded that the chicken can serve as a carrier for the infective larvae of M. apri.
