This study was done to identify correlates of carotid artery ultrasonography's measurement and Inyoung pulse in college students. We measured the amplitude of Inyoung pulse, Chongu pulse, ratio of Inyoung to Chongu and ratio of Chongu to Inyoung on 30 college students. Also, We measured the Distance, Diameter), RI(resistivity index), S/D(systolic, diastolic ratio), PI(pulsatility index), PSV(peak systolic velocity), EDV(End diastolic velocity), Vmean using carotid artery ultrasonography. The data was analyzed by Pearson's correlation coefficient using SAS program. The results were as follow. Results showed a positive correlation between Inyoung pulse and diameter by carotid artery. It showed a positive correlation between Inyoung pulse and S/D. Also, It showed a positive correlation between Inyoung pulse and PSV. As a result, the strength of Inyoung pulse related with the diameter of carotid artery and blood flow velocity.

Objectives : Clear and detailed analysis on Pulse-taking on both Carotid and Wrist Pulses is an absolute prerequisite if it is to be applied in real practice or its practical value proven. Methods : The original notes found in Suwen and Lingshu, their translations, and conventional studies regarding Suwen LiuJieCangXiangLun's Pulse-taking are compared and analyzed to find cases within medical texts where this method was used and to get an idea of the direction taken by the conventional study. Results : The ilsung, esung, samsung, and sasung of Carotid (or wrist pulses) refers that the pulse is one-, two-, three-, four-fold in differences. Refrainment should be practiced while comparing carotid and wrist pulses. Rather, they need to be compared with their normal states. Used by Luo Tianyi in Ming Dunasty, this method of pulse-taking was used for (radial artery) when diagnosing and treating the degree of seriousness of food injury. The measurement of maximum blood flow velocity using TCD done recently proved the validity of this pulse-taking, and it's been used for alleviating hypertension or tinnitus through acupuncture, or abating intractable diseases (around carotid). Conclusions : The obscurity of the measuring method of this pulse-taking can be resolved, and the problem which occurs while comparing carotid and wrist pulses can be solved. Even though there are differences in opinion regarding the positions when comparing the two pulses, their practical values are acknowledged since their usages in diagnosis, treatments, experiments, and researches have yielded positive results to a degree. They may not be used that often, but they are nonetheless under utilization.

The pulse waveforms of a carotid artery in the neck and a radial artery in the hand wrist were individually measured by using clip-type pulsimeter equipped with a permanent and Hall device. The pulse transit time and the pulse wave velocity obtained through comparison of two pulse waveforms were analyzed each other. A value of the pulse wave velocity was about 8.5 m/s similar to one measured by a conservative method. This result suggests that the clip-type pulsimeter as the reproducible and reliable one oriental diagnostic medical device can be predicted to any atherosclerosis state in the cardiac circulatory system.

A patient was 29 year old house wife who was admitted to the Yonsei University Medical Center on 6 th of Nov., in 1970, with chief complaints of complete loss of bilateral visual acuity, generalized weakness, frequent palpitations, claudication of masseter muscles and intermittent fainting. These symptoms were developed 5 years prior to admission. Physical finding on admission revealed complete loss of bilateral visual acuity, absence of both radial and carotid pulse, but there was good femoral and popliteal pulse. She couldn't open her mouth as she desired and had weakness of mastication. Radiological findings of plane chest PA were not significant. Aortogram(Cineangiogram) showed non-visualization of both carotid and subclavian arteries. It showed only innominate and interal mammary artery preoperatively. The operative findings were as follows: There were complete obliterative changes in both common carotid and subclavian arteries, and periarteritis in the innominate artery. Tube Dacron Prosthesis Bypass with V-arm between innominate artery and both common carotid arteries was performed after thromboendarterectomy. Histopathological finding of the thromboend arterectomy specimen was compatible with pulseless disease, which showed marked fibrous thickening of intima and a diffuse inflammatory cell infiltration of the whole layers. Her postopererative course was uneventful. Follow up aortogram(Cineangiogram) was taken on 11th postoperative day, which revealed both common carotid arteries patent. Her preoperative Subjective symtoms disappeared remarkably, such as her visual acuity improved much, fainting and vertigo disappeared completely and she can go to bath room without difficulty and help. Another patient was 34 year old house wife who was admitted on August, 1964 with chief complaints of frequent fainting and progresive visual loss. She was operated only thromboendarterectomy of both common carotid arteries. Postoperative course was smooth and subjective symptoms were disappeared.

Objectives: We evaluated the association between common carotid artery intima-media thickness (CCA-IMT), brachialankle pulse wave velocity (baPWV), carotid plaque, and peripheral arterial disease (PAD) as indicators of macroangiopathy and diabetic retinopathy as an indicator of microangiopathy in type 2 diabetic patients. Methods: We analyzed 605 type 2 diabetic patients registered at a public health center in Korea. Following overnight fasting, venous blood and urine samples were collected and analyzed. The CCA-IMT, levels of carotid plaque, baPWV, and ankle-brachial index (ABI) of the subjects were assessed. We used non-mydriatic fundus photography to diagnose diabetic retinopathy. Multiple logistic regression analyses were used to evaluate the association between macroangiopathy and diabetic retinopathy. CCA-IMT and baPWV were divided into tertiles: CCA-IMT, 0.39 to 0.65 mm, 0.66 to 0.78 mm, and 0.79 to 1.30 mm; baPWV, 9.9 to 15.8 m/s, 15.9 to 18.9 m/s, and 19.0 to 38.0 m/s. Results: The association between baPWV and diabetic retinopathy remained significant after adjustment, with an increasing odds ratio (OR) in the second tertile (OR, 2.41; 95% confidence interval [CI], 1.27 to 4.55) and the third tertile (OR, 4.63; 95% CI, 2.33 to 9.21). No significant differences were observed in carotid plaque, PAD, and each tertile of CCA-IMT. Conclusions: BaPWV was associated with diabetic retinopathy, while CCA-IMT, carotid plaque, and PAD were not. This study suggests that the association between macroangiopathy and microangiopathy may be attributable to functional processes rather than structural processes within the vascular system.

The patient was 47-year-old male who had suffered from aphasia and hemiplegia of the right side, but mental state was alert. On physical examination, BP was 130/80 mmHg in the right arm, but not checked in the left arm. The pulses of the left common carotid, brachial, and radial arteries were not palpable. The pulses of the right femoral, popliteal, and dorsalis pedis arteries were weakly palpable. Brain CT Scan revealed cerebral infarction of the left hemisphere. Aortogram showed occlusion of the left common carotid, and the right internal carotid and common iliac arteries. Subclavian steal phenomena were observed in the delayed aortogram. Double extra-anatomic bypasses; Axillo-Axillar bypass and Femora-Femoral bypass, were performed in the local anesthesia at two stages, because of risk of major operation under general anesthesia. Postoperatively, all pulses except for pulse of the left common carotid artery were equally palpable. On discharge, the hemiplegia of the right side was improved and able to walk with assistance.

Objectives : This study was conducted to examine the association between the carotid artery intima-media thickness (IMT), plaque and cardiovascular risk factors according to gender and age. Methods : The data used for this study were obtained from 1,507 subjects (691 men, 816 women), aged 20-74 years, who participated in 'Prevalence study of thyroid diseases' in two counties of Jeollanam-do Province during July and August of 2004. The body mass index (BMI) and waist hip ratio (WHR) were calculated by anthropometry The blood pressure, pulse rate, pulse pressure, total cholesterol, triglyceride, HDL cholesterol and fasting blood sugar level were also measured. Ultrasonography was used to measure the carotid artery IMT and plaque. IMT measurements were performed at 6 sites, including both common carotid arteries, and the bulb and internal carotid arteries. The definition of the 'mean IMT' was mean value obtained from these 6 sites. Results : The ${\pm}$ standard deviation IMT values were $0.65{\pm}0.14\;and\;0.60{\pm}0.13mm$ in men and women (p<0.001), respectively. The data were analyzed according to gender and the 50 year age groups. In a multiple linear regression analysis, age and hypertension were positively associated with the mean IMT in both men and women, aged<50 years. Age, total cholesterol and smoking (current) were positively associated with the mean IMT in men $(\geq50\;years)$. Age was positively associated with the mean IMT in women $(\geq50\;years)$, but the HDL cholesterol level was negatively associated. The prevalence of plaques was 44.2%(196/443) in men and 19.4%(89/459) in women, for those greater than 50 years of age. In a multiple logistic regression analysis, age (OR=1.090, 95%CI=1.053-1.129), HDL cholesterol (OR=0.964, 95%CI=0.944-0.984), total cholesterol (OR=1.009, 95%CI=1.002-1.017)and BMI (OH=0.896, 95%CI=0.818-0.983) were independently associated with plaques in men; whereas, age (OR=1.057, 95%CI=1.012-1.103), HDL cholesterol (OR=0.959, 95%CI=0.932-0.986), pulse pressure (OR=1.029, 95%CI=1.007-1.050) and triglycerides (OR=0.531, 95%CI=0.300-0.941) were independently associated with plaques in women. Conclusions: There were significant gender and aging differences in the association between the IMT, plaque and cardiovascular risk factors. Therefore, for the prevention of atherosclerosis, selective approaches should be considered with regard to gender and age factors.

In this paper, we implemented a computerized pulse diagnosis system for the developement of pulse diagnosis algorithms and the generalization of the pulse diagnosis. The system consists of the hardware and software. The hardware detects pulse waves and inputs the waves into the computer system, while the software not only manages and analyzes the input pulse wave data but also privides the database. In order to clinically test the developed pulse diagnosis system, we applied the carotid-radial pulse diagnosis algorithm to the system. As the results, it is found that the genralizatio of the pulse diagnosis is possible.

Object : The purpose of this study was to investigate the correlation of atherosclerosis risk factors and pulse wave velocity (PWV) of carotid-femoral artery with Sasang constitution. This study also aimed to investigate the relationship between PWV and risk factors of atherosclerosis, including serum cholesterol and homosisteine, hs-CRP. Methods : We enrolled 160 patients without experience strokes who visited our hospital for a medical examination from January 1, 2008 to April 30, 2010 except patients whose body constitutions were undetermined according to QSCCII. We investigated the correlation between serum cholesterol values, blood pressure, body mass index(BMI), homosistein, hs-CRP and PWV. Pearson's correlation and partial correlation analysis were applied to examine the relationship between PWV and risk factors of atherosclerosis. Result : Among the 160 subjects, 54 were Taeumin, 54 were Soyangin, and 52 were Soeumin. The prevalences of high BMI (P-value <0.01), high hs-CRP(P-value <0.05), and high PWV(P-value <0.05) of Taeumin were higher than those of the other constitutions. PWV of carotid-femoral artery was significantly different among the three constitutional groups(Taeumin: $8.12{\pm}1.64m/sec$, Soyangin: $7.48{\pm}1.16m/sec$, Soeumin: $7.49{\pm}1.12m/sec$)(P-value <0.05). This research has show a statistical significance between the average amount of carotid-femoral artery PWV that is higher in Taeumin. Age factor of Taeumin was the effective determinant of the increase of mean PWV of carotid-femoral arteries. Conclusions : There were significant differences in the prevalence of atherosclerosis according to Sasang constitution. This study showed that atherosclerosis was more prevalent in Taeumin. Therefore, according to our results, risk of atherosclerosis was higher in Taeumin than among other constitutions.

The acupuncture procedures in Hwangjenaekyung (黃帝內經) was different to modern ones in many aspects. Especially, the role of pulse diagnosis in acupuncture was totally different and the pulse diagnosis was essential part in acupuncture therapy in Hwangjenaekyung era. We found four noteworthy features on the pulse diagnosis before and after acupuncture in Hwangjenaekyung : (1) Pulse diagnosis was a mandatory process in acupuncture (2) Doctors who used pulse diagnosis in 12 meridians (十二經脈遍診脈法), pulse diagnosis in 9 points of 3 body parts (三部九候脈法), and comparative pulse diagnosis between radial artery and carotid artery (人迎寸口對比脈法) followed the former rule ((1)). (3) The major pulse features to detect before and after acupuncture were conversion between the vacuous pulse (虛脈) and the replete pulse (實脈), and conversion between slippery pulse (滑脈) and rough pulse (澁脈). (4) Deukki (得氣, Deqi) was synonym of Kiji (氣至), and it referred to the changes of arterial pulse, not the sensation followed by acupuncture manipulation.
