To determine whether topical application of trimix extracts of Mylabris phalerata Pall., Arisaematis Rhizoma and Pinelliae Rhizoma Ternata lead to affects on the hair growth activity in C57BL/6N mice. To examine the hair growth activity of the extracts of Mylabris phalerata Pall., Arisaematis Rhizoma and Pinelliae Rhizoma Ternata gross, microscopic, and immunohistochemical method were performed. In order to examine the mRNA expression of hair growth related substance, RT-PCR method was performed. Experimental group I on day 14, The most extensive hair growth activity was observed in whole skin area of all the mice whose hair had been clipped. Brdu immunoreactive cells of all the experimental groups were more heavily stained in epidermis, bulge, outer root sheath, inner root sheath, subcutaneous tissue, hair bulb and cutaneous trunci muscles than that of control group on day 12 of hair growing cycle in C57BL/6N mice. VEGF immunoreactive density of all the experimental groups was more heavily stained in epidermis, bulge and cutaneous trunci muscles than that of control group on day 12. FGF and c-kit immunoreactive cells of all the experimental groups were heavily stained in epidermis, outer root sheath, inner root sheath and cutaneous trunci muscles on day 12. PKC-$\alpha$ immunoreactive density of all the experimental groups was mildly stained in epidermis and cutaneous trunci muscles than that of control group on day 12. On day 12, the expression of bFGF (138%, 119%, 120%), VEGF (146%, 144%, 133%), IGF-1 (165%, 141%, 119%) and PLI (121%, 116%, 123&) in each experimental groups was more increased than that of control group. On day 16, The expression of IGF-1 (126%, 149%, 151%) in all the experimental group was more increased than that of control group (100%). The expression of bFGF (92%, 94%) and VEGF (101%, 97%), PL1 (102%, 109%) in all the experimental group was more decreased than that of experimental group I, II on day 12. But the expression of bFGF (109%) and VEGF (127%), and PL1 (105%) in each experimental group III was more increased than that of control group (100%). These experiments suggest that trimix extracts of Mylabris phalerata pall., Arisaematis Rhizoma and Pinelliae Rhizoma Ternata may stimulate the topical hair growth activity and its experimental group I can be useful for treatment of alopecia areata.

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.

Carnosine is a dipeptide $(\beta-alanyl-L-histidine)$ found in mammalian brain, eye, olfactory bulb and skeletal muscle at high concentrations. Its biological functions include antioxidant and anti-glycation activities. The objectives of this study were to investigate anti-diabetic effects of carnosine as determined by blood glucose levels, glucose tolerance test (GTT), glycosylated hemoglobin, and serum biochemical and lipid levels in streptozotocin-induced diabetic mice. There were five experimental groups including normal (ICR mice), control (saline), and three groups of carnosine at doses of 6, 30, and 150 mg/kg b.w.. Carnosine was orally administered to the diabetic mice everyday for 12 weeks. There was no significant difference in body weight changes in carnosine-treated groups compared to the control. The treatments of carnosine at the dose of 6 mg/kg significantly decreased the blood glucose level compared with the control at 2 and 4 weeks. The treatments of carnosine at the doses of 6 and 30 mg/kg significantly decreased the blood glucose levels in GTT and glycosylated hemoglobin compared with the control. Carnosine significantly increased total proteins compared with the control. Carnosine at the dose of 6 mg/kg significantly decreased total cholesterol and triglyceride in the serum compared to the control. These results suggest that carnosine at a low level has a hypoglycermic effect resulting from reduction of blood glucose and that a carnosine-containing diet or drug may give a benefit for controlling diabetes mellitus in humans.

Objective: An experiment was conducted to determine the relationship between the KAP11.1 and the regulation wool fineness. Methods: In previous work, we constructed a skin cDNA library and isolated a full-length cDNA clone termed KAP11.1. On this basis, we conducted a series of bioinformatics analysis. Tissue distribution of KAP11.1 mRNA was performed using semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) analysis. The expression of KAP11.1 mRNA in primary and secondary hair follicles was performed using real-time PCR (real-time polymerase chain reaction) analysis. The expression location of KAP11.1 mRNA in primary and secondary hair follicles was performed using in situ hybridization. Results: Bioinformatics analysis showed that KAP11.1 gene encodes a putative 158 amino acid protein that exhibited a high content of cysteine, serine, threonine, and valine and has a pubertal mammary gland) structural domain. Secondary structure prediction revealed a high proportion of random coils (76.73%). Semi-quantitative RT-PCR showed that KAP11.1 gene was expressed in heart, skin, and liver, but not expressed in spleen, lung and kidney. Real time PCR results showed that the expression of KAP11.1 has a higher expression in catagen than in anagen in the primary hair follicles. However, in the secondary hair follicles, KAP11.1 has a significantly higher expression in anagen than in catagen. Moreover, KAP11.1 gene has a strong expression in inner root sheath, hair matrix, and a lower expression in hair bulb. Conclusion: We conclude that KAP11.1 gene may play an important role in regulating the fiber diameter.

An investigation was carried out to study the effect of two housing systems on physiological responses and energy expenditure of sheep in a semi-arid region of India. Two types of housing management were adopted. First was a shed- $6{\times}3\;m^2$ structure with all the four sides of 1.8 m chain link fencing with a central height of 3 m. The roof was covered with asbestos sheets and with mud floorings. Second was an open corral- $6{\times}3\;m^2$ open space with all the four sides covered with 1.8 m chain link fencing. Thirty-four (32 ewes and 2 rams) sheep of native Malpura breed aged about 18 months (body weight 28 kg ewes; 35 kg rams) were grazed together on a 35 ha plot of native range. All the sheep were grazed as a flock from 08.00 to 17.00 h during a yearlong study. The flock was divided into two groups (16 ewes+1 ram) in the evening and housed as per the systems (Shed and Open Corral). Dry and wet temperatures were recorded at 06.00 h and 21.00 h using a wet and dry bulb-thermometer both inside the shed and in the open corral and temperature humidity index (THI) was calculated. There was significant (p<0.05) difference in the THI between shed and open corral in all the seasons, indicating that shed was always warmer compared to open corral. Rectal temperature (RT) of both the groups of sheep was similar during morning as well as evening throughout the seasons. There were significant (p<0.05) differences in the skin temperature (ST) and respiration rate (RR) between the two groups at both the measurements in all the seasons. Highest energy expenditure (EE) was recorded inside the shed at 21.00 h (224 kJ/h) during monsoon and lowest at 6.00 h during winter (119 kJ/h). There was a significant (p<0.05) difference between the EE inside the shed and that in the open corral. It was concluded that housing had significant effects on the physiological responses and EE of sheep. Provision of housing at night was stressful during monsoon (with less rainfall) and summer, whereas it was protecting the sheep from acute cold during winter in a semi-arid region of India.

Introduction : Exercise has been suggested as an important nursing strategy in which to help elderly maintain functional performance and to enhanced quality of life. Most of exercise study has been reported on fitness exercise such as walking, swimming, dance etc for health of elderly. There have been few reports about exercise on the promotion of small and fine movement of elderly. The purpose of this pilot study was to determine an effect of 6 weeks hand and finger exercise in home to improve hand muscle strength such as grip strength and finger pinch pressure. Materials and Methods Design: This pilot study was used one group pre and post-test design. Sample: Twelve elderly women above 60 years of age or older living in community were selected by convenient sampling. Procedure: Signed informed consent was obtained prior to participate in this study. The authors met elderly and taught hand and finger exercise, daily a week for 6 weeks, within 30 minutes per session. But exercise frequency and strength were not same. Instruments: Left and right grip strength were measured by Bulb Dynamometer(made in USA) and left and right pinch pressure were measured by Baseline Hydraulic Pinch Gauge(made in USA). Data analysis: Discriptive data analyses were performed on all variables. Wilcoxon matched-pairs Signed-Ranks test were used to find difference of grip strength and pinch pressure between pre and post exercise using SPSS 10.0 for Window. Results: Samples age ranged from 60 to 73, Mean age was 65.3. All were women. Ten elderly were diagnosed osteoarthritis and one had DM. After six weeks hand and finger exercise, Left and right grip strength were higher than those of before exercise(Z=-2.667, P<0.01 ; Z=-3.065, p<0.01). And left pinch pressure after hand and linger exercise were higher than that of before pinch pressure (Z=-2.315, p<0.05). But Right pinch pressure was not shown significant change(Z=-1.099, p>0.05). Conclusions: Although this study was limited by the sample size and design, the findings provide some important implications for community based exercise nursing intervention. Short term (six weeks) exercise of hand and linger is shown to be useful as nursing intervention to maintain routine daily activities such as eating, writing, grip something for elderly.
