  • Transducin (T), the heterotrimeric guanine nucleotide binding protein in rod outer segments, serves as an intermediary between the receptor protein, rhodopsin, and the effector protein, cGMP phosphodiesterase. Labeling of T with dansyl chloride (DnsCl) inhibited its light-dependent guanine nucleotide binding activity. Conversely, DnsCl had no effect on the functionality of rhodopsin. Approximately 2-3 mol of DnsCl were incorporated per mole of T. Since fluoroaluminate was capable of activating DnsCl-modified T, this lysine-specific labeling compound did not affect the guanine nucleotide-binding pocket of T. However, the labeling of T with DnsCl hindered its binding to photoexcited rhodopsin, as shown by sedimentation experiments. Additionally, rhodopsin completely protected against the DnsCl inactivation of T. These results demonstrated the existence of functional lysines on T that are located in the proximity of the interaction site with the photoreceptor protein.

  • Vesicular-arbuscular mycorrhizae (VAM) fungi naturally colonise American ginseng roots and this relationship is highly beneficial to enhance plant productivity. Our goal was to determine the effect of adding two Glomus species (Glomus etuticatum, G. intraradices) on survival, photosynthetic capacity, growth, morphology and root ginsenoside content of one-year-old American ginseng plants grown in a broadleaf forest. While our study revealed that VAM inoculations significantly affected root morphology and Re ginsenoside content, the survival, photosynthetic capacity and root growth of American ginseng plants were not significantly influenced by VAM inoculations. Surface area and volume of rootlets were 16-25% higher for ginseng grown in VAM-inoculated soil compared to those grown in the control plots. Also, Re ginsenoside content was 18 % higher in YAM-inoculated roots compared to controls.

  • The fourth branchial clef cyst is very rare entity ana only 35 cases have been reported worldwide. There have been some controversial attempts to prove its anatomical route through embryological background. However some reports even suggested that it might be impossible to prove its entity anatomically Recently, reports are coming out on the diagnostic approaches using anatomical pathway. We experienced in 45 years old woman, one case of lateral cystic neck mass which were anatomically presumed to be fourth brachial cleft cyst.

  • Karyotype of the ricessh Orygias latipes (Temminck et Schlegel) was investigated using 151 specimens of eleven populations in the southern Korea. Based on the karyotype analysis, two distinct chromosomal groups were found. One group, occurring in the Kum River, the Mankyong River, the Dongjin River, the Ysngsan River and the SEmjin River had a diploid chromosome number of 46 and arm number of 70, which contained one pair of "large" metacentric chromosomes. The other group, occurring in the Tamjin River, the Hyongsan River andthe all four island populations observed had a diploid chromosome number of 48 and arm number of 68. These results showed that 0. latipes of 6 inland populations was identical with the Chinese population in diploid number, arm number and presence of "large" metacentric chromosome, while the present species of island populations ana populations of the Tamjn R. and Hyongsan R. was similar to the Japanese population in chromosome number and arm number. The karyotype variation in populations indicated that karyotypes will probably provide useful information in studying zoogeography of this species.phy of this species.

  • Thermal analysis of new designed heat-sink models was carried out according to the natural ana the forced convection using computational fluid dynamics(CFD). Heat resistance of wave type, top vented wave type and plate type of heat sink was compared with each other As the direction of fin and air flow are vertical(z-axis), it is shown that radiant heat performance of all of heat sinks was superior than other experimental conditions. Especially, the heat resistance of top vented wave heat sink was $0.17^{\circ}C/W$(forced convection) and $0.48^{\circ}C/W$(natural convection). The radiant heat performance of heat sink was increased with increasing the height of fin and the width of fin pitch.

  • To investigate the efficacy, tolerance of Vibramycin Precon PT-122 M and to determine the nature, incidence and severity of side effects of this formulation, 19 patients with urogenital infections were studied. 1. Vibramycin Precon PT-122 M reduced the signs and symptoms of various urogenital infections so as to determine the overall efficacy as good or satisfactory. 2. Intravenous injection of PT-122 M was generally well tolerated in all patients except 2 case of discontinuation because of adverse effect. 3. PT-122 M showed mild to moderate side effects but clinical features ana response to therapy were not influencea by those side effects.

  • Systemic lupus erythematosus is a disease of unknown etiology that affects many organ system and is characterized by the presence of multiple autoantibodies that participated in immunology mediated tissue injury. A 36 years-old female patient was admitted to ward due to high fever and erythematous rash on face and hole body. She exhibited itching sense, joint pain, nausea, fatigue, sensitivity to light. The homatologic finding revealed anemia, decrease of lymphocyte, low platelet count, but LE cell, Anti nuclear antibody(ANA) were negative. In the point of Differentiation of Syndrome(辨證), SLE can be thought to be a category of Seasonal febril disease(溫病). This subject diagnosed as Domination of intense evil heat(熱毒熾盛), and was administrated with Chungonpadocyem-gamibang(淸瘟敗毒飮加味方). The clinical and laboratory findings of our patient were improved by herb medication, acupuncture therapy and general supportive measure.

  • Three species of tapeworms infect humans in their adult stage (Taenia solium, Taenia saginata and Taenia asiatica). The 3 are flat, opaque white or yellowish, and exceptional long segmented parasites, measuring 1 to 12 m in their adult stage. In this review, the development of the knowledge regarding the first species, mainly focused on understanding how the larval stage or cysticercus is transmitted to humans, is described. The second species is a cosmopolitan parasite that only causes taeniosis and not cysticercosis; therefore, it will not be included. Information on the third species, which is presently being produced, since this species was recognized as such only at the end of the 20th century, will be discussed at the end of this review.

  • Effect of ginseng polysaccharide fraction was examined for $CCl_4$-induced hepatotoxicity in vitro and in vivo. In $CCl_4$-injured primary cultured rat hepatocytes, treatment of the polysaccharide fraction (0.1, 0.3, 1.0 mg/ml) significantly Inhibited the release of LDH and GOT into the culture medium in a dose-dependent manner. Oral administration of the polysaccharide fraction (100, 200 mg/kg) inhibited the decrease of body weight and the increase of the ratio of liver to body weight in $CCl_4$-intoxicated rats. Elevation of GOT, GPT and ALP activity in the serum by $CCl_4$-induced hepatotoxicity was suppressed by administration of ginseng polysaccharide fraction. MDA levels increased in the serum as well as in the liver tissue by treatment with $CCl_4$ showed a tendency to be 연w in the rats given to the polysaccharide fraction. These results suggest that the polysaccharide fraction may be active substance responsible for antihepatotoxic effect of Panax ginseng.
