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.

성장 호르몬 투여 및 알코올 발효사료 급여가 한우 비거세우 및 거세우의 혈액성분, 도체특성 및 수익성에 미치는 영향

This study was performed to examine the effects of recombinant bovine somatotropin (rBST) and fermented alcoholic feedstuff(FAF) on blood metabolites, carcass characteristics and profitability. Sixteen Hanwoos(bulls; 8, steers; 8) with average 143㎏ of body weight were randomly assigned to bull control group(BC), steer control group(SC), bull group(BrA) treated with rBST and FAF, and steer group(SrA) treated with rBST and FAF. Sustained release rBST(0.03㎎/㎏/body weight) was administered biweekly and dose of rBST was adjusted monthly according to body weight increase. The blood glucose content was higher in the groups treated with rBST and FAF than control groups. The blood cholesterol contents tended to be lower in the treatment groups (BrA, 120.5 mg/dl; SrA, 104.0 mg/dl) than in the control groups (BC, 141.0 mg/dl; SC, 125.5 mg/dl). No significant difference between the groups of bulls and steers were found in the blood triglyceride concentrations as well as the albumin contents. The rib eye area of BC and BrA were 70 and 72 cm2, respectively, which are slightly larger than the area of SC and SrA. The treatment did not affect the backfat thickness both in bulls and steers. The marbling scores of BC and BrA appeared as No. 1 and No. 2, respectively, and No. 3 and No. 4 were obtained in SC and SrA. Lower non saturate fat concentrations were observed in the treatment groups (BrA, 64.30%; SrA, 59.59) than in control groups (BC, 58.98%; SC, 58.09%). Saturated fatty acids and amino acids contents were slightly more improved in the treatment than in the control. Average auction prices of BC and BrA were 7,900 and 8,089 wons per 1kg of carcass, respectively, whereas the prices of SC and SrA were 9407 and 9866 wons per 1kg of carcass, respectively. It is concluded that the treatment with rBST and FAF can improve the growth performance such as marbling scores and rib eye area and increase the auction prices.

비육전ㆍ후기의 한우 비거세우에 알코올 발효사료 급여와 소 성장호로몬 투여가 육성능력에 미치는 영향

This study was conducted to examine the effect of fermented alcoholic feedstuff (FAF), sustained-release recombinant bovine somatotropin(rBST) on growth performance and body size of Korean native cattle, Hanwoo. The experiment was carried at the Livestock Breeding Station in Kangwon-do with fourteen bulls of two groups, control and treatment. Seven bulls per each group were allocateed. In control group, bulls were treated with total mixed ration(TMR) for the whole experimental periods. In treatment group, bulls were treated with TMR+FAF+rBST for the fattening period and TMR+FAF for the finishing period, respectively. The results are summarized as follows ; Average daily gains(ADG) of control and treatment groups were 0.86 and 1.11kg during the fattening period. ADG of treatment group were 29.1% higher than that of control group. For the whole experimental period, the fattening period and finishing period, ADG in control and treatment groups were 0.69 and 0.79kg, respectively, which shows 14.5% improvement of ADG in treatment group. Dry matter intake(DMI) was higher in treatment group than in control group during the finishing, fattening or whole experimental period. Feed conversion efficiencies in fattening period were 8.65 for control group and 6.93 for treatment group which shows improving 19.9% of feed conversion efficiency for treatment group, while 12.38 for control group and 14.48 for treatment group in finishing period. There were no significant differences between control and treatment group in feed conversion efficiency for the whole experimental period. Overall results indicate that the favorable feeding system to produce growth performance is TMR+FAF+rBST feeding during the fattening period and TMR+FAF feeding in treatment during the finishing period.
