1). To find the effective insecticides and its timing for the control of the bamboo-shoot cutworm, Bambusiphila vulgaris BUTLE R, this experiment was carried out at Tam-Yang in Chula-namdo from May to June in 1963 in Korea. 2). Endrin, Folidol, and Diazinon were more effective than sumithion, Aldrin, and EPN. .B). The best timing of insecticidal spraying was in 5 days after hatching front the eggs. 4). Since this experiment is the result only tried just once, I hope that the same experiment should be repeated several times and consequently effective of killing insects and the best timing for sprinkling insecticides should be also Investigated.

The inhibitory effect of Inula sesquiterpene lactones on the growth of Phaseolus vulgaris was tested and the abnormality of the stem organization caused by the lactones was also examined. The longitudinal growth of the young stem and the expansion of the young leaf were stopped by the application of the lactones. However, this inhibitory effect was appeared and strictly restricted within the treated area. So the young shoot was observed for possible bending as a result of the unilateral application of the lactones. When the application of the lactones into the medium, the growth of the plant was entirely repressed. However, the growth of shoot and re-initiation of root were started after the plant was transfered to the lactone free medium. And partial reversal of inhibition of the stem growth was achieved by the additions of gibberelline and the lactones.

The combination of Simian Virus40 (SV40)'s large T antigen with its replication origin is commonly used in molecular studies to enhance the expression of heterogeneous genes through multiplying the plasmid copy number. There are no reports related to the impact of the SV40 T antigen on plant, multiple fissional, cell-type. This study explores the response of two multiple-fission microalgal cells, Scenedesmus quadricauda and Chlorella vulgaris, to the expression of the T-antigen, with aim of applying SV40 T-antigen to increase the expression efficiency of foreign genes in the two species. Different levels of low-expression have been constructed to control the expression of SV40 T antigen using three heterogenous promoters (NOS, CaMV35S, and CMV). Chlorella cultures showed slowdown in the growth rate for samples harboring the T antigen under the control of CaMV35S and CMV promoters, unlike Scenedesmus cultures which showed no significant difference between samples and could have silenced the expression.

The macroscopic and microscopic redox potentials of tetrahemoprotein, cytochrome c3 from Desulfovibrio vulgaris(Hildenborough) (DvH) were estimated from 1H NMR and differential pulse polarography(DPP). Five sets of NMR resonances were confirmed by a redox titration. They represent cytochrome c3 molecules in five macroscopic redox states. The electron transfer in cytochrome c3 involves four consecutive one-electron steps. The saturation transfer method was used to determine the chemical shifts of eight heme methyl resonances in five different oxidation states. Thirty two microscopic redox potentials were estimated. The results showed the presence of a strong positive interaction between a pair of particular hemes. Comparing the results with those of Desulfovibrio vulgaris Miyazaki F (DvMF), it was observed that the two proteins resemble each other in overall redox pattern, but there is small difference in the relative redox potentials of four hemes.

From June to August 2021, we surveyed diseases affecting beet (Beta vulgaris subsp. vulgaris) plants in Cheolwon, Hoengseong, and Pyeongchang regions in Gangwon Province, Korea. We observed severe leaf spot symptoms, such as brown to dark circular or irregular spots on the leaves, in plants. Disease incidence in the plant leaves in the fields investigated at the three locations ranged from 1 to 80%. Five single-spore isolates of Phoma sp. were obtained from the diseased leaves and identified as Neocamarosporium betae based on their cultural, morphological, and molecular characteristics. Three isolates of N. betae were subsequently tested to confirm their pathogenicity in beet plants via artificial inoculation. The tested isolates caused leaf spot symptoms in the inoculated plants, similar to those observed in the plants in the investigated fields. Therefore, our findings revealed N. betae as the pathogen causing beet leaf spot in Korea.

This study was conducted to evaluate the effects of Zizyphus vulgaris supplementation on growth performance, blood cortisol and meat quality characteristics in finishing pigs. The total of thirty-six [Duroc${\times}$Yorkshir${\times}$Landrace] pigs ($91{\pm}2.11$ kg average initial body weight) were used in a 30-days assay. Dietary treatments included 1) CON (basal diet), 2) T1 (basal diet for 15 days and 0.1 % Zizyphus vulgaris for 15 days) and 3) T2 (0.1 % Zizyphus vulgaris for 30 days). The ADG (Average daily gain), ADFI (Average daily feed intake) and ADG/ADFI during the feeding period were not significantly differences among the treatments (p>0.05). Backfat thickness of pigs fed CON was higher than those of T1 and T2 (p<0.05). The appearance rate of A or B carcass grade was in T1 (74%) and T2 (84%) was significantly higher than that in CON (58%) (p<0.05). Pigs fed Zizyphus vulgaris 0.1 % for 30 days tended to decrease on blood cortisol compared with pigs fed CON and T1. But, there was not significantly difference among the treatments (p>0.05). The Hunter's L/sup */ (lightness) value of loin in the pork fed CON was higher than that of loin in the pork fed T1 and T2 (p<0.05). After 7 days, the L/sup */ value of loin in the pigs fed T2 was higher increased than that of pigs fed T1 and CON (p<0.05). However, a/sup */ and b/sup */ values were not affected by dietary Zizyphus vulgaris (p>0.05). There were not found remarkable differences in sensory properties (marbling, firmness and color) among the treatments. The results from the present study suggest that Zizyphus vulgaris could be a effective feed additive to improve meat quality of pigs. However, further research is needed to investigate effects of carcass characteristics.

The proposal of the $CO_2$ ocean sequestration necessitates a thorough understanding of its consequences to aquatic organisms. This paper describes acute toxic responses to high $CO_2$ environment of a cephalopod, Octopus vulgaris. O. vulgaris was chronically cannulated in the abdominal aorta and recovered in a restrained chamber. Acid base variables as well as ion concentrations were estimated in samples of the blood collected from recovered O. vulgaris. 100% mortality occurred within 72h during exposure to 3%-$CO_2$ environment. Hemolymph pH significantly decreased after 30 min during exposure to 1%-$CO_2$ environment without any compensation thereafter. $[HCO_3^-]$ significantly increased from 2.2 mM at 0h to 7.8 mM at 8h, but gradually decreased thereafter. Hemolymph ions $([Cl^-],\;[Na^+],\;[K^+])$ showed no significant changes. O. vulgaris may be more sensitive than teleost, yellowtail, flounder and dogfish.

Activation of the NLRP3 inflammasome is critical for host defense as well as the progression of inflammatory diseases through the production of the proinflammatory cytokine IL-1β, which is cleaved by active caspase-1. It has been reported that overactivation of the NLRP3 inflammasome contributes to the development and pathology of acne vulgaris. Therefore, inhibiting activation of the NLRP3 inflammasome may provide a new therapeutic strategy for acne vulgaris. In this study, we investigated whether auranofin, an anti-rheumatoid arthritis agent, inhibited NLRP3 inflammasome activation, thereby effectively treating acne vulgaris. Auranofin suppressed NLRP3 inflammasome activation induced by Propionibacterium acnes, reducing the production of IL-1β in primary mouse macrophages and human sebocytes. In a P. acnes-induced acne mouse model, injection of P. acnes into the ears of mice induced acne symptoms such as redness, swelling, and neutrophil infiltration. Topical application of auranofin (0.5 or 1%) to mouse ears significantly reduced the inflammatory symptoms of acne vulgaris induced by P. acnes injection. Topical application of auranofin led to the downregulation of the NLRP3 inflammasome activated by P. acnes in mouse ear skin. These results show that auranofin inhibits the NLRP3 inflammasome, the activation of which is associated with acne symptoms. The results further suggest that topical application of auranofin could be a new therapeutic strategy for treating acne vulgaris by targeting the NLRP3 inflammasome.

Objective : This study was performed to find out the differential points of the pattern identification for Acne vulgaris and suggest them to the clinic setting Methods : We searched the papers that suggest patterns identification for Acne vulgaris through China National Knowledge Infrastructure(CNKI), Oriental Medicine Advanced Searching Integrated System(OASIS), Korean Traditional Knowledge Portal(KTKP), Korean Studies Information Service System(KISS). We looked through all the papers, excluded unintended papers, and finally chose some papers that are suitable for inclusion. Then, We extracted all the patterns of Acne vulgaris and chose frequently suggested patterns. Finally we extracted symptoms from selected patterns and arranged them in order of frequency. Results and Conclusions : 1. We found 215 papers and chose 17 papers (Korean : 6, Chinese : 11). 2. We extracted total 67 demonstrations and chose Patterns of Wind-Heat, Damp-Heat, Phlegm and Static blood, Disharmony of the Thoroughfare and Controlling vessels. 3. In Acne vulgaris, the pattern of Wind-Heat tends to have a red papule, sometimes pustule, pain with itching, burning sensation, tidal reddening of the cheeks, white head or black head. The pattern of Damp-Heat tends to have a pustule, node, redness and swelling, pain and greasy skin. The pattern of Phlegm and Static blood has a tendency to be a nodule or cystoma that is hard, dark, painful, long lasting and hard to recover and easy to recur with a scar, pimple, pigmentation. The pattern of Disharmony of the Thoroughfare and Controlling vessels tends to be exacerbated before menstruation, have a small papule that is not easily treated under the chin or around the mouth.

생활수준이 높아지면서 수경재배된 신선채소의 수요가 늘어나고 있으며, 비트와 같은 서양근채류의 이용도 증가하는 추세여서 근채류의 양액재배도 증가하리라 기대된다. 특히 비트의 경우 색소의 원료로도 이용이 많으므로 재배가 늘 것으로 보인다. 비트는 중성 내지 약알칼리성 토양에서 생육이 가장 좋은 것으로 알려져 있는데. 현재 국내 대부분의 밭토양은 산성이므로 비트 재배에 적함하지 않다고 본다. (중략)
