  • To investigate the correlation between the clinical features and the expression of p53, PCNA, and Ki-67 of the head neck squamous cell carcinoma, immunohistochemicalstaining of p53, PCNA, and Ki-67 on the paraffin embedded tissue blocks of 116 surgically removed specimens were done. The staining intensity was divided as grade 1 to grade 3 and the results were statistically analysed. 1. The positive reation rates of cell proliferation markers (PCNA and Ki-67) were higher than that of p53. There was significant correlations of the PCNA and Ki-67 expression but there was no significant correlations between p53 and PCNA or p53 and Ki-67. 2. There were no significant correlation between the expression of p53, PCNA and Ki-67 and tumor site or tumor size. 3. There was no significant differences in the positive response according to the nodal status. The node metastasis groups revealed that higher proportion of grade 3 staining of PCNA and Ki-67 than node negative group. From the above results it is concluded that p53 and cell proliferation markers PCNA and Ki-67 might have their unique mechanism involving in the growing and progression of tumor. Overexpression of p53 does not appear to represent an independent prognostic marker in head neck squamous cell carcinoma.

  • Experimental Study of Taegye($KI_3$) Taebaek($SP_3$) Draining Acupuncture on the Improvement of Cerebral Blood flow and Arterial Blood Pressure. Objectives : This study was designed to investigate the effects of acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining and determine the mechanism of action of PCBL by measuring the changes of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats. Methods : This study was designed to investigate whether acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining affect Regional cerebral blood flow(rCBF), Mean arterial blood pressure(MABP) in normal rats. To make manifest whether acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining was mediated by inhibitor of cyclooxygenase or guanylate cyclase which diate arterial diameter. Results 1. Acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining significantly increased rCBF but decreased MABP. This result suggests that Acupuncturing on Taegye($KI_3$) Taebaek($SP_3$) draining might significantly increase rCBF by dilating arterial diameter. 2. Acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining induced increase of rCBF was significantly inhibited by pretreatment with indomethacin (1 mg/kg, i.p.), an inhibitor of cyclooxygenase. 3. This result suggests that the action of Acupuncture on Taegye($KI_3$) Taebaek($SP_3$) draining might be mediated by cyclooxygenase.

  • Purpose: To evaluate the expression of Her2/neu and Ki-67 in benign and malignant gallbladder lesions, and to establish correlations with clinico-pathologic parameters. Materials and Methods: A retrospective analysis was conducted on formalin fixed paraffin embedded (FFPE) benign (n=25) and malignant gallbladder (n=25) tissue samples. Hematoxylin and eosin stained slides of each case were reviewed for: type of malignancy (whether adenocarcinoma, squamous cell carcinoma, or any other type), grade (well, moderate, and poor), depth of invasion, pre-neoplastic changes in adjacent mucosal epithelium like metaplasia and dysplasia. Immunohistochemistry for Her 2 neu and Ki-67 was performed and data analysis was conducted using SPSS 17 software. Chi-square test was used to compare categorical/dichotomous variables. P value of ${\leq}0.05$ was considered significant. Results: The difference of Her 2 neu expression and Ki67 index between benign and malignant groups was found to be statistically significant. Her2/neu positivity did not have any significant correlation with various clinicopathological parameters other than liver involvement. 5 cases of gallbladder cancer showed both Her2/neu and Ki67 positivity. Ten cases were Ki67 positive but Her2/neu negative while one case was Her2/neu positive but Ki67 negative. Conclusions: The present study demonstrated overexpression of Her2/neu and Ki67 in gallbladder cancer. A trend of decreasing Her2/neu expression with increasing grade of tumor was observed. Furthermore, greater Ki67 positivity was found in cases with lymph node metastasis and distant metastasis. Future studies with a larger number of patients will be required to precisely define the correlation of Her2/neu expression and Ki67 positivity with clinicopathological parameters. The results however are encouraging and suggest evaluation of Her2/neu as a candidate for targeted therapy.

  • Background: Breast cancer is the commonest female cancer worldwide and its propensity to metastasize negatively impacts on therapeutic outcome. Several clinicopathological parameters with prognostic/predictive significance have been associated with metastatic suppressor expression levels. The role of metastatic suppressor gene (MSG) KiSS1 in breast cancer remains unclear. Our goal was to investigate the possible clinical significance of KiSS1 breast cancer. Materials and Methods: The study was conducted on 87 histologically proven cases of breast cancer and background normal tiisue. Quantitative reverse transcriptase polymerase chain reaction (qRT PCR) and immunohistochemistry (IHC) were used to investigate KiSS1 at gene and protein levels, respectively, for correlation with several patient characteristics including age, family history, hormonal receptor status, stage, tumor size, nodal involvement and metastatic manifestation and finally with median overall survival (OS). Results: Our study revealed (i) KiSS1 levels were generally elevated in breast cancer vs normal tissue (P < 0.05). (ii) however, a statistically significant lower expression of KiSS1 was observed in metastatic vs non metastatic cases (P = 0.04). (iii) KiSS1 levels strongly correlated with T,N,M category, histological grade and advanced stage (p<0.001) but not other studied parameters. (iv) Lastly, a significant correlation between expression of KiSS1 and median OS was found (P = 0.04). Conclusions: Conclusively, less elevated KiSS1 expression is a negative prognostic factor for OS, advancing tumor stage, axillary lymph node status, metastatic propensity and advancing grade of the breast cancer patient. Patients with negative KiSS1 expression may require a more intensive therapeutic strategy.

  • The present condition of study on the wave-resonance for the bio-KI is observed. And the probroms of reception attendent on the stimulation of wave is observed centering around the sensory organ. The results is as follows: In the wave-resonant stand point, the tendency of studying on KI is showed in the several field all over the world. Because it is originated radionics, the wave-resonant tools of MRA insistenting minute-magnetism-resonance-apparatus need the more severe data in the side of electric circuit. The wave resonance apparatus according to the frequency occurance transmits low-frequency's vibration ratio to the electric stimulating aspect. The wave-water is considered on the application of wave-resonance transcription on the water, and needs the comprehension of torsion-field level. The wave-stimulation of the bio-KI and the reception of the sensory-organ is observed the connection of the sensory-organ and it's corresponding wave. The informations recorded in the wave are distinguished patternly. And the several shaping waves transmit the informations each other through the resonnance. The wave theory is explained the LEE(理) as the wave-pattern and the KI(氣) as the revelation of the patterned-wave in the LEE-KI theory(理氣論), moreover the SHIN(神) as the information of the wave-pattern and the KI as the energy of the wave and the JEUNG(精) as the material of the wave in the JEUNG-KI-SHIN theory(精氣神論). In this point, the study on the wave-resonance of bio-KI is thought that it is significantly in the study method for oriental medicine. The sum of the wave makes the moving body and forms the universe. It means that the several wave patterns gather and form new field. The pattern is a kind of the information and the information is not materially. The information of wave-pattern is the arrangement and the combination of the material source.

  • The following conclusions are produced by the consideration of Bojungikki-tang(補中益氣湯) from the view point of Hyungsang medicine. A review on the explanation and provisions of Bojungikki-tang stipulated in 'Donguibogam(東醫寶鑑)' results in the idea that the main purpose of Dongwon(東垣) and various application in clinic by Jeesan(芝山) cannot be understood without the deep comprehension of ki(especially Jungki and Wonki) and the fire. Jungki(中氣, the middle warmer ki) is the ki of stomach. Wonki(元氣, the original ki) is a combination of innate Jung(先天之精, Ki stored between the two kidneys) and acquired Jung(後天之精, Ki of the stomach) and the sources of five Jang and six Bu, twelve meridians and triple warmer. Yin fire is referred to the ministerial fire of spleen, liver and kidney. Excess or lack of the ministerial fire can cause a disease and especially the excess of it is harmful to original ki. Deficiency of original ki is thought to be a cause of allergic diseases. Damages on the original ki by the abdominal surgery lead to a disease. Pale complexion, long face and the long limbs are considered as the Hyungsang of deficiency of Jung ki by Jeesan. Clinical cases of Bojungikki-tang in Hyungsang medicine draw the following conclusions ; Bojungikki-tang is usually prescribed to the person who has one of the following Hyungsang : Bangkwang type, pale complexion, long face, short-sight, astigmatism and wrinkles on face. Bojungikki-tang can be applied to the every disease caused by the deficiency of original ki regardless of name and symptoms of disease.

  • Liver cancer has a high prevalence, with majority of the cases presenting as hepatocellular carcinoma (HCC). The prognosis of metastatic HCC has hardly improved over the past decade, highlighting the necessity for liver cancer research. Studies have reported the ability of the KiSS1 gene to inhibit the growth or metastasis of liver cancer, but contradictory research results are also emerging. We, therefore, sought to investigate the effects of KiSS1 on growth and migration in human HCC cells. HepG2 human HCC cells were infected with lentivirus particles containing KiSS1. The overexpression of KiSS1 resulted in an increased proliferation rate of HCC cells. Quantitative polymerase chain reaction and immunoblotting revealed increased Akt activity, and downregulation of the G1/S phase cell cycle inhibitors. A significant increase in tumor spheroid formation with upregulation of β-catenin and CD133 was also observed. KiSS1 overexpression promoted the migratory, invasive ability, and metastatic capacity of the hepatocarcinoma cell line, and these effects were associated with changes in the expressions of epithelial mesenchymal transition (EMT)- related genes such as E-cadherin, N-cadherin, and slug. KiSS1 overexpression also resulted in dramatically increased tumor growth in the xenograft mouse model, and upregulation of proliferating cell nuclear antigen (PCNA) and Ki-67 in the HCC tumors. Furthermore, KiSS1 increased the angiogenic capacity by upregulation of the vascular endothelial growth factor A (VEGF-A) and CD31. Based on these observations, we infer that KiSS1 not only induces HCC proliferation, but also increases the metastatic potential by increasing the migratory ability and angiogenic capacity.
