Objective : The purpose of this study is to understand conspicuous features of geroderma with visceral manifestation theory(臟象論). Methods : We categorized skin aging into wrinkles, hyperpigmentation, dry skin and face flush. After investigating the reason, histological changes and mechanism of each classification in western medicine, we interpreted them according to the malfunction of five viscera(五臟) in Korean medicine. Result : The results are as follows. 1. Pathologic change of dermis and subcutaneous fat makes wrinkles. We consider wrinkles as the malfunction of the spleen(脾). 2. Irregular synthesis and disproportion of melanin makes hyperpigmentation. We consider hyperpigmentation as the malfunction of the liver(肝). 3. Dry skin is attributed to a subtle disorder of epidermal maturation. We consider dry skin as the malfunction of the lung(肺). 4. Facial flush is detected in rosacea and menopausal hot flush, which are both related with blood vessel abnormality. We consider facial flush as the malfunction of the heart(心) Conclusion : We interpreted the pathologic changes and mechanism of skin aging in western medicine as the decrease of five viscera(五臟) in visceral manifestation theory(臟象論) of Korean medicine. Further studies are needed to apply these hypothesis to clinical diagnosis and treatment.

Transgenic animals have been widely used for developmental biology studies, as disease models, and even in industry such as transgenic bioreactor animals. For transgenic birds, quail has the great advantages of small body size, short generation time, and frequent egg production. To date, retroviral or lentiviral transduction has been used to generate transgenic quail for various purposes. However, the efficiency of transgenic offspring production with these methods is relatively low and viral vector usage has safety issues. Unfortunately, non-viral transgenesis has not been established in quail due to a deficiency of stem cell and germ cell culture systems. In this study, we established a direct in ovo lipofection method that could be used to create transgenic quail without germline-competent cells or viruses. To optimize the injection stage during embryo development, the liposome complex (containing piggyBacCMV-GFP and transposase plasmids) was introduced into an embryonic blood vessel at 50 hr, 55 hr or 60 hr. GFP expression was detected in various tissues (heart, kidney, liver and stomach) on day 12 of incubation under a fluorescence microscope. Additionally, GFP-positive cells were detected in the recipient embryonic gonads. In conclusion, the direct in ovo lipofection method with the piggyBac transposon could be an efficient and useful tool for generating transgenic quail.

The authors has observed the histopathologically and histochemically on the effect of the garlic and garlic oil to the liver and kidney of rats. In order to confirm the histochemical changes of the metabolism of polysaccarides, the periodic acid Schiff reaction was applied. The 30 albino adult male rats weighing about 150 grames from the National Institute of Health were housed individualy and devide into 3 experimental groups: Group C: stock diet group Group B: stock diet-garlic group Group A: stock diet-garlic oil group Group C was fed with stock diet only through out this experimental period, Group B was fed with stock diet supplemented with garlic homogenator to be 1%, and Group A was fed with stock diet supplemented with the garlic oil to 0.05%. The garlic oil used in this experiments was extracted by author. And all rats was fed during 10 weeks. The histopathological and histochemical results were shown in each figure. According to the all results, the following concIusions were drawn. 1) In the garlic oil administrated groups, congestion of the sinusoid was subsided and the liberation of the Kupffer's cells were observed. 2) In garlic administrated groups, fatty metamorphosis in hepatic cells, and slight liberation of Kupffer's cells in sinusoidal walls were observed. Connective tissue proliferation and collagen bundle were observed. 3) The connective tissue and blood vessel wall in portal area Were reacted intensely with PAS stain. The hepatic cells Were reacted intensely with PAS stain in control group and moderately or slightly in garlic and garlic oil administrated group. 4) There were no significant differences in collecting and Henle's loops in each groups, but narrowing of lumen of the distal tubules were observed in garlic oil administrated group. 5) The basement membrane of the tubules and the connective tissues of the vessel wall in Kideny were reacted intensely with PAS stain in each groups. In control and garlic administrated groups. the brush border of the proximal tubules were reacted intensely with PAS stain, but epithelium of the Heine's loop, proximal, distal and collecting tubules were reacted moderately. In garlic oil administrated-group, there were tendency of decreasing of PAS stain in each tubules.

Objectives : The purpose of this study is to investigate Acute and Subacute Toxicity, and Anti-cancer Effect of H Herbal-acupuncture on mice and rats. Methods : Balb/c mice were injected intraperitoneally with H Herbal-acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were experimented in the same way for subacute toxicity test. H Herbal-acupuncture was injected into abdomen of mice having S-180 cancer cell line. Result : 1. During the test, $LD_{50}$ could not be counted since there was no expired subjects. 2. In an acute toxicity test, the loss of motility and reflex action was observed, but weight increased in the treatment group, compared with those in the normal group (P<0.05). 3. In an acute toxicity test of serum biochemical values of mice, glucose increased in the treatment group II while total cholesterol was increased in the all treatment groups (P<0.05). 4. In a subacute toxicity test, a little loss of motility and reflex action was observed in the treatment group. Weight of mice in the treatment group decreased on the 28th day. 5. In a subacute toxicity test, liver weight was decreased but lung weight of mice increased in the all treatment groups (P<0.05). 6. As a result of measuring Complete Blood Count test (CBC) of rat, HCT was decreased in treatments even though it was not significant, compared with the normal group (P<0.05). 7. In a serum biochemical value test of subacute toxicity, total protein and albumin decreased in the all treatment groups. Creatinine, glucose, GOT increased in the treatment group I compared with the control group. Alkaline phos-phatase decreased in treatment II group, compared with the control group (P<0.05). 8. Median survival time that was measured in the rats treated with sarcoma-180 cancer cell Median decreased in the treatment group, compared with the control group (P<0.05). 9. Natural killer cell activity showed significant reduction at 100:1 and 10:1 E/T ratio while it increased at 50:1 E/T ratio. It is inferred that there was an error in the experiment (P<0.05). 10. In an interleukin-2 productivity test, even though it decreased in lung cancer, and increased in abdomen cancer, but it was only a small difference (P<0.005). 11. After injecting B16F10 cell into a capillary vessel of C57BL/6 mice and generating metastasized lung cancer, the lung was examined with the naked eye. It was not possible to see metastasized cancer in the all groups on the seventh day but the cancer was viewed on the fourteenth day. The number and volume of metastasized cancer in the treatment group enlarged in the treatment group, compared with the control group. Conclusion : According to the results, H herbal-acupuncture took no effects in cancer.

Objectives: This survey was done in order to find out how Korean medical doctors derive pattern identification for acupuncture prescriptions in treating low back pain in real clinical practice. Methods : The survey questionnaire was developed by the committee of experts who major in acupuncture & moxibustion or statistics for acupuncture clinical trial protocol development. The questionnaires were distributed via e-mail to 75 members of Korean Acupuncture & moxibustion society from March 26th to April 14th in 2009. 57 members completed answers, and the computerized data were analyzed by SPSS 17.0 statistical program. Results : 1.57 Korean medical doctors selected meridian pattern identification based on the course of the meridians(44.6%), visceral pattern identification(32.1%), pattern identification based on cause of disease(14.3%) as the most commonly used pattern identification methods for acupuncture prescription when treating low back pain patients in real clinical practice. 2. In meridian pattern identification based on the course of the meridians, gallbladder meridian of hypochondriac region(13.0%), bladder meridian of lateral low back region(11.2%), governer vessel of central low back region(11.7%) were selected 3. In visceral pattern identification, yang deficiency of kidney(20.2%), deficiency of kidney(19.3%), liver(16.7%), yin deficiency of kidney(14.0%), violence qi of kidney(8.8%), small intestine(7.9%) were selected. Conclusions : In our e-mail survey, Korean medical doctors answered that Meridian Pattern Identification based on the course of the meridians is the most often used diagnosis method. Visceral pattern identification, pattern identification based on cause of disease, meridian pattern identification based on symptom and pattern identification based on qi-blood-yin-yang theory in order of frequency used, were selected for low back pain diagnosis in real clinical practice.
