  • To analyze the developmental changes in soma diameters of digastric motoneurons, wheat-germ agglutinin conjugated horseradish peroxidase (WGA-HRP) was injected into the digastric muscle and visualized the retrogradely HRP-labeled motoneurons through tungstate/tetramethylbenzidine (TMB) and following diaminobenzidine (DAB) reactions. The results obtained from Sprague-Dawley rats at postnatal days 1 (P1), 10 (P10) and 30 (P30) indicated as follows: firstly, soma diameters of digastric motoneurons showed unimodal distribution in all postnatal days examined; secondly, the period of P1 to P10 (period 1) showed about 2 times faster growth rate than that of P10 to P30 (period 2); thirdly, the smallest soma examined in each postnatal day exhibited slower growth rate with that of the largest one (increase ratio in soma diameters from P1 to P30, smallest vs. largest = 1.62 : 1.93); Finally, relative growth rates a day showed again that period 1 had faster growth rate than that of period 2. Consequently, developmental changes in soma diameters of digastric motoneurons resulted in very different growth rates between both periods. This implies that the growth of the soma is almost completing within P10 and thereafter growing slowly. The period 1 and 2 are corresponding to sucking and sucking/masticatory period, respectively. Therefore present study providing morphological changes in soma diameters of digastric motoneurons suggests that both periods and their different growth rates of the motoneurons in each period may closely be related with each other.

  • This study was performed to investigate the effects of prolonged immersion vaccination in a dilute vaccine on the farmed olive flounder, Pararlichthys olivaceus. Juvenile olive flounders were immersed in the several diluted ($10^0$, $10^{-1}$, $10^{-2}$ and $10^{-3}$) commercial edwardsiellosis bacterins (5㎎/ℓ) for 2min (short immersion, SI) and 24 h (prolonged immersion, PI). After immunization, fish were analyzed to investigate on non-specific (serum lysozyme and bactericidal activity), specific immune responses (antibody agglutinin titer) and resistances against Edwardsiella tarda infection. The PI of the commercial vaccine diluted with $10^{-1}$ and $10^{-2}$ showed better results over the untreated control in terms of serum lysozyme, bactericidal activities and resistance against E. tarda infection. These results suggest that the prolonged treatments of the diluted vaccine might be a new approach improving the vaccination potential.

  • The frequency of fulminant peumonia due to Mycoplasma pneumoniae is relatively rare despite the high prevalence of Mycoplasma species infection in the general population. We report a case of mycoplasma pneumonia complicated with severe ARDS, overt hemolytic anemia and hepatitis. He had high titers of antimycoplasma antibody and cold agglutinin. Despite erythromycin administration, the pneumonic infiltration on chest radiography was not resolved, and mechanical ventilation was needed for 16 days. During the therapeutic course, his hemoglobin decreased. After the administration of prednisolone, his hemoglobin increased and pneumonic infiltration was totally resolved. He had a progressively favorable course and could be discharged in relatively good clinical condition.

  • Phytase improves the bioavailability of phytate phosphorus in plant foods to humans and animals, and reduces the phosphorus pollution of animal waste. We have engineered the cell surface of the yeast. Saccharomyces cerevisiae, by anchoring active fungal phytase on its cell wall, in order to apply it as a dietary supplement containing bioconversional functions in animal foods and a whole cell bio-catalyst for the treatment of waste. The phytase gene (phyA) of Aspergillus niger with a signal peptide of rice amylase 1A (Ramy1A) was fused with the gene encoding the C-terminal half (320 amino acid residues from the C-terminus) of yeast ${\alpha}-agglutinin$, a protein which is involved in mating and is covalently anchored to the cell wall. The resulting fusion construct was introduced into S. cerevisiae and expressed under the control of the constitutive glyceraldehydes-3-phosphate dehydrogenase (GPD) promoter. Phytase plate assay revealed that the surface-engineered cell exhibited a catalytically active opaque zone which was restricted to the margin of the colony. Additionally, the phytase activity was detected in the cell fraction, but was not detected in the culture medium when it was grown in liquid. These results indicate that the phytase was successfully anchored to the cell surface of yeast and was displayed as its active form. The amount of recombinant phytase on the surface of yeast cells was estimated to be 16,000 molecules per cell.

  • Objectives : This study was carried out to compare the effects of Eejin-tang, Hyangsaeejin-tang and Naeso-san extracts on indomethacin-induced gastric mucosal lesions in mice. Methods : Experimental mice were divided into six groups. The normal group had no gastro-inflammation. In the control group, gastro-inflammation was elicited by indomethacin. Misoprostol, Eejin-tang, Hyangsaeejin-tang and Naeso-san group were those in which misoprostol, Eejin-tang extract, Hyangsaeejin-tang extract and Naeso-san extract were administered after gastro-inflammation is elicited. This study examined the anti-inflammation effects and distribution of mucus secreting cells, zonula occludin-1 (ZO-1), heat shock protein (HSP) 70, periodic acid-schiff reaction stain (PAS), peanut agglutinin (PNA), cyclooxygenase-1 (COX-1), 5-bromo-2'-deoxyuridine (BrdU), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-${\kappa}B$) p65, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Results : 1. The hemorrhagic erosion and damaged mucus secreting cell, the positive reaction HSP70 increased in the control group, but decreased in the Eejin-tang, Hyangsaeejin-tang and Naeso-san groups. 2. The positive reaction of ZO-1, PAS, PNA, COX-1 and BrdU decreased in the control group, but increased in the Eejin-tang, Hyangsaeejin-tang and Naeso-san groups. 3. The positive reaction of NF-${\kappa}B$ p65, iNOS and COX-2 increased in the control group, but decreased in the Eejin-tang, Hyangsaeejin-tang and Naeso-san groups. Conclusions : Among the three extracts, the effects were in the order of Naeso-san, Hyangsaeejin-tang and Eejin-tang group, Naeso-san being the most effective.

  • Purpose: Alpha-fetoprotein (AFP), Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3), and Golgi protein 73 (GP73) levels have been widely used as tumor markers for the diagnosis of hepatocellular carcinoma (HCC). The aim of this study was to investigate whether these tumor markers could be used to monitor short-term treatment response and recurrence of HCC in patients undergoing radiofrequency ablation (RFA). Methods: Between July 2012 and July 2013, 53 consecutive patients with newly diagnosed HCC were prospectively enrolled in this study. Among these, 32 patients underwent RFA, after which they were followed up prospectively at the First Hospital of Jilin University in China. Results: AFP, AFP-L3, and GP-73 values pre-RFA were not associated with tumor size, whereas AFP and GP-73 levels tended to be associated with tumor number, the presence of vascular invasion, deterioration of liver function, advanced-stage disease, and a poor performance status. GP-73 levels were dramatically elevated in the patients with hepatitis C-associated HCC. Neither pre-RFA nor 1-month post-RFA tumor marker values were associated with short-term outcome. The short-term recurrence rate of AFP-positive patients measured 1 month post-RFA was obviously higher than that of AFP-negative patients. Conclusions: AFP and GP-73 values were associated with clinical variables representing tumor growth and invasiveness, and the AFP value measured 1 month post-RFA was a strong predictor of short-term recurrence in patients with HCC.

  • Object: Death rate due to hypertension, atherosclerosis, ischemic heart disease and cerebral infarction induced by Westernized diet and increased average life span is on the rise. Decrease in blood circulation, activation of thrombus generation and intravascular lipid accumulation, cited as the principal causes of the above mentioned diseases in recent studies, result in circulatory disturbance and blood vessel obstruction leading to ischemic cell death of heart, brain and peripheral vessels. Method: We investigated the biochemical changes in microvascular permeability, aggregation of platelet and the intravascular lipid accumulation in induced-diabetic rat using Streptozotocin. We also studied the effects of Woohwangcheongsirn-won after oral administration on blood circulation, platelet function and lipid metabolism. The results are as follows: I. Woohwangcheongsim-won increased blood circulation in microvessels. 2. Woohwangcheongsim-won increased the reduced erythrocyte deformability in diabetes. 3. Woohwangcheongsim-won induced the reduction of contents of 2, 3-DPG, but failed to affect the reduced contents of ATP in erythrocyte in diabetes. 4. Woohwangcheongsim-won reduced the activity of Ca/sup 2+/-ATPase in the membrane of erythrocyte. 5. Woohwangcheongsim-won reduced the platelet aggregation evoked by platelet agglutinin factor. 6. Woohwangcheongsim-won reduced the production of platelet-derived granules. 7. Woohwangcheongsim-won reduced the production of metabolites of arachidonic acid in diabetes, and also reduced the production of increased thromboxane B2. 8. Woohwangcheongsim-won reduced the synthesis of oxidized LDL-cholesterol. In conclusion, Woohwangcheongsim-won enhanced blood circulation in microvesseles, erythrocyte deformability and inhibited the increased platelet aggregation and the synthesis of oxidized LDL-cholesterol in diabetes. Therefore Woohwangcheongsim-won is believed to positively affect blood circulation (J Korean Oriental Med 2002;23(2):164-179)

  • In order to elucidate whether capsaicin applied topically acts as a pain-producing subastance or as a tastant, neuronal activities of the chorda tympani nerve(CN), lingual nerve(LN), solitary tract nucleus(STN), and trigeminal nucleus(TGN) were recorded while thermal and taste stimuli, and capsaicin were being applied topically, and algesics intra-arterially to the tongue of cats anesthetized with ${\alpha}-chloralsoe$. In addition, the STN neurons were examined after wheat germ agglutinin-horseradish peroxidase(WGA-HRP) was applied to the CN. The CN fibers responded to taste and thermal stimuli, algesics, and capsaicin. Responses to capsaicin were significantly correlated with those to taste and thermal stimuli. The LN fibers mainly responded to mechanical and thermal stimuli, algesics, and capsaicin. Responses to capsaicin were significantly correlated with those to algesics. The STN neurons responded to taste and thermal stiumli, algesics, and capsaicin. Responses to capsaicin were significantly correlated with those to taste and thermal stiumli in somewhat different fashion from those of the CN fibers. The TGN neurons mainly responded to mechanical stimuli, algesics, and capsaicin. Correlations between responses to capsaicin and any others were not significant. After WGA-HRP was applied to the CN, the STN neurons which receive input from the CN were identified largely in the medio-ventral portion to the solitary tract. These results suggest that capsaicin produce taste as well as pain sensation. Sensory information evoked by capsaicin can be conveyed to the STN, especially medio-ventral portion, via the CN as gustatory information on the one hand, and to the STN or TGN via the LN as noxious information on the other. In addiation, the noxious information may be conveyed to the STN via the CN.

  • Antibodies to Propionibacterium acnes in patients with tumor, leprosy, schizophrenia and normal human were measured by using a microtiter bacterial agglutination test. They were found in all sera examined, including normal human sera. It was comfirmed that a microtiter bacterial agglutination test on P. acnes is found to be an easy and satisfactory method for the measurement of antibody to P. acnes. The agglutinin titers of tumor patients, particularly hepatoma and gastric cancer patients, were significantly lower as compared with those of normal human sera. Antibody titers in leprosy patients were somewhat lower when compared with those in normal human sera. Antibody titers of lepromatous type of leprosy patient were lower than those of tuberculoid type. However, antibody levels were the same in schizophrenia patient and normal human. No correlation between antibody titers and age or sex of the patients and normal human was found.

  • Mycoplasma pneumoniae is a common cause of community-acquired pneumonia in children, with a peak incidence at 5-14 years. Extrapulmonary manifestations occur in 20-25% of patients with M. pneumoniae infection. Most auto-antibodies that cause immune hemolytic anemia in humans are cold agglutinins. The formation of cold agglutinins is frequently observed during M. pneumoniae infections, and cold agglutinin disease usually occurs during M. pneumoniae infections. Nevertheless, severe hemolysis is exceptional. If a patient has any underlying disease related to hemolysis, it is possible to accelerate hemolysis. Hereditary spherocytosis is a common cause of hereditary hemolytic anemia resulting from red blood cell membrane defects. Hemolysis of red cells may result from corpuscular abnormalities or extracorpuscular abnormalities, such as immune or non-immune mechanisms. We report a case of hereditary spherocytosis associated with severe hemolytic anemia due to Mycoplasma pneumonia.
