  • The dopaminergic receptors were consisted of two distinct subtypes, $D_1$and $D_2$, each having different function. The present study was attempted to investigate the effects of R(-)-2,10,11-trihydroxy-N-n-propylnoraporphine (TNPA), a dopamine $D_2$receptor agonist, on renal function in dog. TNPA (5.0~15.0 $\mu$g/kg), when given into the vein, produced a dose-dependently antidiuresis along with the decrease in osmolar clearance ( $C_{osm}$) and urinary excretion of sodium and potassium ( $E_{Na}$ , and $E_{K}$). It also increased reabsorption rates of sodium and potassium in renal tubules ( $R_{Na}$ , $R_{K}$) without any changes in glomerular filtration rate (GFR), renal plasma flow (RPF) and free water clearance ( $C_{H2o}$). TNPA (0.5~1.5 $\mu$g/kg/min) infused into a renal artery decreased urine flow both in the experimental and the control kidneys. TNPA (1.5~5.0 $\mu$g/kg) administered via the carotid artery also greatly exhibited antidiuresis even at intravenously ineffective doses. Changes of renal function by TNPA given into both the renal artery and the carotid artery were almost the same aspect to those induced by intravenous TNPA. These results obtained from the present study suggest that TNPA produces antidiuresis by increasing the reabsorption rates of electrolytes in renal tubules, mainly distal tubule, through changing of central function.unction.

  • To obtain the basic data for protective roles and first-aid of radiation hazard, the present studies were carried out to evaluate the decontamination of radiostrontium by the First-Aid drugs. Each mouse was administered intraperitoneally dose of sodium alginate 5mg, $CaNa_3DTPA$ 8.4mg and saline 5ml following the internal contamination with 1 $\mu$Ci of strontium as $^{85}SrCl_2$. $^{85}Sr$ was determined by the radioactivity of body burden, urinary excretion, fecal excretion and organ distribution by Ge-detector and MCA. The results are summarized as follows. 1. Effective half life on whole body retention $^{85}Sr$ was determined at 33 hours. 2. The decontamination effect of First-Aid durgs on the body $^{85}Sr$ burden were increased $CaNa_3DTPA$ (4.7 times), sodium alginate (1.7 times) and saline (2.4 times) respectively. 3. Strontium were excreted through urine (35.4%), feces (64.4%) and other (0.2%). But on the $^{85}Sr$ excretion routes following First-Aid drugs treatment, strontium-85 mainly were excreted through urine after $CaNa_3DTPA$ and saline treatment, and was excreted through feces after sodium alginate treatment. 4. The organ distribution of strontium-85 is vertebra, femur, sternum and liver in order Finally, the extrapolations from these data to victims were suggested that the rapid administration of $CaNa_3DTPA$, sodium alginate and saline simultaneously were markedly increased the decontamination effects on the internal contamination of radiostrontium.

  • A 16-year-old cat presented with a 2-week history of anorexia and lethargy. Radiography revealed a soft-tissue opacity, heart-shaped mass between the descending colon and urinary bladder. Ultrasonography showed a large uterine body with a heterogeneously hypoechoic, thickened wall and hypoechoic intraluminal fluid. Computed tomography revealed a large, fluid-filled uterine mass with contrast enhancement, without evidence of regional lymph node or pulmonary metastasis. Ovariohysterectomy was performed and leiomyosarcoma was confirmed by histology. No notable abnormalities were observed during the 1-year postoperative follow-up periods. This report describes the diagnostic imaging and treatment of a rare case of feline uterine leiomyosarcoma.

  • In this study attempts were made to explore effects of the water and alcohol extracts of Junci Herba on the renal function of dogs. The water extract (in a dose 15 mg/kg, i.v.) and alcohol extract (in a dose 1.5 mg/kg, i.v.) elicited a diuretic response and produced a marked diuresis during bicarbonate infusion whereas no diuresis ensues during infusion of hydrochloric acid. The ratios of potassium and sodium excreted in urine $(K^+/Na^+)$, pH of urine, Cosm (osmolar clearance) and $C_{H_2O}$ (free water clearance) increased but hemodynamic states changed little with both extracts. All the observed facts can be best explained on the assumption that Junci Herba inhibits the carbonic anhydrase in the tubule. Thus it produces the effect by increasing urinary potassium and sodium.

  • Jarcho-Levin syndrome is a congenital disorder characterized by several vertebral and costal anomalies. Other abnormalities have also been described, including neural tube defects, Arnold-Chiari malformation, renal/urinary tract abnormalities, hydrocephalus, hydroureteronephrosis, and meningomyelocele. We describe a spondylocostal dysplasia form of Jarcho-Levin syndrome that was prenatally diagnosed at 11 weeks of gestation and surviving. Although the patient had sporadic-type Jarcho-Levin syndrome, with normal karyotype and no family history of disease, the assessment of inheritance patterns and genetic counseling for the parents was important to inform them about the potential risks.

  • This study evaluated the effects of TMC (trace mineral-fortified microbial culture) supplementation on growth performance, carcass characteristics, and meat quality parameters of Hanwoo steers during the last 4 months of finishing period. The TMC was a combination of 0.4% trace minerals, 20.0% Na-bentonite, and 79.6% feedstuffs, which was inoculated with a mixed microbial culture (Enterobacter ludwigii, Bacillus cereus, B. subtilis, Lactobacillus plantarum, and Saccharomyces cerevisiae). Twenty-four steers were blocked by initial BW ($634{\pm}16kg$) and randomly allocated to one of two treatments (control vs. 3.3% TMC). The effect of TMC supplementation on the growth performance was not significant. There was no incidence of urolithiasis in TMC-fed steers. However 3 out 12 steers (25%) fed the control diet were observed to have urinary calculi. The carcass yield and meat quality parameters were not affected by TMC supplementation, however marbling score was increased in TMC-fed steers (P = 0.08). There was no effect of TMC treatment on the chemical composition of longissimus dorsi muscle (LM). The TMC supplementation increased concentrations of manganese (P < 0.01), cobalt (P = 0.02), iron, and copper (P = 0.06) in LM. In conclusion, TMC treatment did not negatively affect growth performance and meat quality parameters, and positively affected the trace minerals profile of LM.

  • The effect of meal service for home-staying, urban elderly with low income on their mineral status and prevalence of clinical symptoms was evaluated. One hundred. One hundred and eighty three subjects were assigned to meal-served(served) and non-served(non-served)groups. A meal containing approximately one half of the RDA for energy, protein, calcium and iron was served as lunch every day to served group at a welfare center. Dietary, biochemical and clinical data were collected before and after 6 months of meal service and the changes of parameters were analyzed with paired t-test. served female showed significantly increased intake of calcium. The mean hemoglobin, serum iron, TIBC and serum copper of female were significantly increase with meal service. The proportion of anemic female compared to reference data on hemoglobin, hematocrit and serum iron were 45.5$\%$, 29.1$\%$ and 16.4$\%$ respectively, but were lowered to 18.2$\%$, 7.3$\%$, and 5.5$\%$ after 6 months of meal service. served male showed significant increase in MCHC, serum copper, and urinary Na. The urinary Ca/Creatinine, which is often used as an index of bone resorption, was decreased significantly in served group. The decrease in the proportion of served women suffering from edema of ankle and diarrhea was most apparent and less women reported feeling clinical symptoms of dizziness, constipation, difficulty in hearing, and coughing after meal service. The symptoms of benumbness of hands and feet and coughing was lowered most among men after meal service. Clinical symptoms of non-served elderly did not show improvement in feeling clinical symptoms except slightly decreased frequency in coughing of female and buzzing sound in the ears and diarrhea of male.

  • Objectives : This study was undertaken to examine the metabolomic changes due to gender and diurnal variation at sampling time and to identify an appropriate time point for urine sampling in epidemiologic studies using metabolomic profiles. Methods : Urine samples were collected twice a day (morning and afternoon) from 20 healthy Korean adults after fasting for 8 hours. The metabolomic assay was investigated using $^1H$ NMR spectroscopy coupled with the principal components analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The metabolites responsible for differentiation between groups were identified through the loading plot of PLS-DA and quantified using Chenomx NMR Suite with a 600 MHz library. Results : Metabolites responsible for differentiation in gender and sampling time were creatinine, trimethyl anine oxide (TMAO), hippurate, mannitol, citrate and acetoacetate. Dimethylamine showed difference only as a factor of diurnal time. The level of creatinine was higher in men compared to women, and the levels of citrate, TMAO, hippurate, mannitol, and acetoacetate were higher in women compared to men. The levels of creatinine, TMAO, hippurate, dimethylamine and mannitol were higher in the morning rather than the afternoon while those of citrate and acetoacetate were higher in the afternoon rather than the morning. Conclusions : Since urinary metabolomic profiles varied by gender and diurnal cycle, urine sampling should be performed at the same time point for all participants in epidemiologic studies using metabolomic profiles.

  • The effects of a newly synthesized $H^+/K^+$ ATPase inhibitor,1-(2-methyl-4-methoxypheny)-4-[(3-hy-droxypropyl)amino] -6-methyl-2,3-dihydropyrrolo (3,2-c) quinoline (DBM-819) , on the central nervous system, isolated smooth muscle, cardiovascular and digestive systems and renal function were investigated in various experimental animals. Oral administration of DBM-819 had no effect on the central nervous system except body temperature of mice slightly decreased at doses of 15 and 50 mg/kg. DBM-819 produced a moderate analgesic effect in acetic acid-induced writhing test in mice at 50 mg/kg (p.o.). In conscious rats, DBM-819 (15 and 50 mg/kg, p.o.) showed a slight increase in blood pressure and a small decrease in heart rate. DBM-819 had an significant effect on agonist-induced contraction of guinea pig ileum at $1.5{\times}10^{-5}g/ml.$ No significant effect of DBM-819 (5 and 15 mg/kg, i.p) on urinary volume or urinary excretion of $Na^+,\;K^+$ and Cl- was observed in rats. DBM-819 had no significant effect on intestinal transport of a semisolid meal in mice at 15 and 50 mg/kg (p.o.). These findings suggest that DBM-819 exerts no significant pharmacological effects on the central nervous system and renal function at 15 mg/kg (p.o.), but produces some effects on the smooth muscle and circulatory system.
