Appetite stimulant ether-soluble neutral extract of a high-grain compound feed was separated into four fractions with an open column of silica gel chromatograph using four carrier solutions containing n-pentane and diethyl ether as 100:0 (Fraction A), 90:10 (Fraction B), 75:25 (Fraction C) and 0:100 (Fraction D). The stimulative effects of the fractions were examined by comparing the intake of hay (with or without the fractions) in two-choice test bioassays with cattle. The Fractions A, B and C of the neutral extract stimulated (p<0.05) hay consumption in cattle, whereas Fraction D had no effect on selective feeding when compared with the control fraction. Furthermore, Fractions A, B and C had higher (p<0.05) feeding stimulative indices (FSI) than that of the Fraction D. The results suggest that chemical stimulants to increase palatability of hay are present in the neutral Fractions A, B and C of high-grain concentrate.

Dairy performances of Pabna cows and its crossbreds with Sahiwal (SL) and Friesian (F) in the Baghabarighat dairying area of Bangladesh were evaluated. Four SL and three F sires were used for the crossbreeding. The exotic sire effect of individuals on their daughters were also evaluated in this study. It showed that the genetic group had a significant (p<0.05) effect on birth weight, age at first heat, calving interval, lactation length and lactation yield. The lowest birth weight (17.9 kg), longest age at first heat (39.2 m) and calving interval (16.3 m) shortest lactation length (199 d) and lowest lactation yield (728 L) were found in Pabna cows. The highest birth weight (22.5 kg). shortest age at first heat (25.5 m) and calving interval (13.7 m), longest lactation length (253 d) and highest lactation yield (1936 L) were found in the F crossbreds. Within the same breed, the effect of individual sire was significant (p<0.05) on age at first heat, lactation length and lactation yield. Individual sire effects of SL bulls differed significantly (p<0.05) but F sires had a non-significant (p>0.05) effect on calving interval in their progeny. The fat % and SNF % in milk and number of services required for conception did not differ (p>0.05) among inter-and intra- breed sire groups.

Purpose: This study is to investigate if the improvement of visual sensory (VS) by amblyopia treatment affects the ocular functions in refractive errors, accommodative errors and phoria at distance and near. Methods: 10 subjects (17 eyes, mean age of $10.7{\pm}2.9$ years) who treated amblyopia completely, were participated for this study. Refractive errors, accommodative errors, and distance and near phoria were compared between before and after treatments of amblyopia. Refractive errors and accommodative errors at 40 cm were measured using openfield auto-refractor (NVision-5001, Shin Nippon, Japan) and using monocular estimated method (MEM) respectively. Phoria was determined at 3 m for distance and at 40 cm for near using Howell phoria card, cover test or Maddox rod. Results: Mean corrected visual acuity (CVA) significantly increased from $0.46{\pm}0.11$ (decimal notation) for before amblyopia treatment to a level of $1.03{\pm}0.13$ for after amblyopia treatment (p < 0.001). For spherical refractive error, hyperopia significantly decreased from $+2.29{\pm}0.86D$ to a level of $+1.1{\pm}2.38D$ (p < 0.05) but astigmatism did not significantly change; $-1.80{\pm}1.41D$ for before treatment and $-1.65{\pm}1.30D$D for after treatment (p > 0.05). Accommodative error significantly decreased from accommodative lag of $+1.1{\pm}0.75D$ to a level of $+0.5{\pm}0.59D$ (accommodative lag) (p < 0.05). Distance phoria significantly changed from eso $2.9{\pm}6.17PD$ (prism diopters) to a level of eso $0.2{\pm}3.49PD$ (p < 0.05), and near phoria also significantly changed from eso $0.4{\pm}2.32PD$ to level of exo $2{\pm}4.9PD$ (p < 0.05). There was a high correlation (r = 0.88, p < 0.001) between improvement of visual acuity and decrease of accommodative lag. Conclusions: Hyperopic refractive error decreased with improvement of CVA or VS by amblyopia treatment. And the improvement of VS by amblyopia treatment also improved accommodative error, and changed phoria coupled with accommodation.

Purpose: To identify factors that influence serum zinc concentrations in children with acute gastroenteritis. Methods: Thirty-two children under 5 years of age (15 boys and 17 girls) were selected randomly among those who visited to an pediatric emergency room of Ehwa Womans University Mokdong Hospital with acute gastroenteritis from May to August 2005. This study estimated the association between serum zinc concentrations and clinical, biochemical variables in patients with acute gastroenteritis. Results: Serum zinc concentration was lower in febrile patients than afebrile patients with acute gastroenteritis ($67.5{\pm}25.3$ vs $85.5{\pm}14.2$, p<0.05). It also was lower in patients with positive C-reactive protein (CRP) than those with negative CRP ($63.9{\pm}25.4$vs $86.7{\pm}13.8$, p<0.05). Serum zinc concentration was negatively correlated (r=-0.494, p<0.05) with CRP concentration, whereas positively correlated with hematocrit (r=0.370, p<0.05), total protein (r=0.474, p<0.05), and albumin (r=0.636, p<0.05). Twelve patients (37.5%) showed very low serum zinc concentration (< $70{\mu}g/dL$) without clinical symptoms of deficiency or growth retardation. Frequency of febrile illness or positive CRP is significantly greater in group with zinc < $70{\mu}g/dL$ than the group with zinc ${\geq}70{\mu}g/dL$ (91.7% vs 55%, p<0.05; 91.7% vs 40%, p<0.05, respectively). Conclusion: In patients with acute gastroenteritis, serum zinc concentration was influenced by various factors such as fever, CRP, and biochemical factors. For evaluating zinc status in the body. factors.

The effect of supplementing the diet of grazing dairy cows with fish oil (FO) and linseed oil (LSO) on milk conjugated linoleic acid (CLA) was investigated. Sixteen Holstein cows (17019 DIM) were assigned into two groups and fed a grain supplement (8.0 kg/d; DM basis) containing 800 g of saturated animal fat (CONT) or 200 g FO and 600 g LSO (FOLSO). All cows grazed together on Sudan grass pasture ad libitum and were fed the treatment diets for 3 wks. Cows were milked twice a day and milk samples were collected during the last three days of the trial. Milk production (24.89 and 22.45 kg/d), milk protein percentage (2.76 and 2.82) and milk protein yield (0.68 and 0.64 kg/d) for the CONT and FOLSO diets, respectively, were not affected (p>0.05) by treatment diets. Milk fat percentage (3.90 and 2.86) and milk fat yield (0.97 and 0.64 kg/d) were lower (p<0.05) with the FOLSO diet compared with the CONT diet. The concentration and yield of milk cis-9 trans-11 CLA were higher (p<0.05) with the FOLSO diet (2.56% of total FA and 16.44 g/d, respectively) than the CONT diet (0.66% of total FA and 6.44 g/d, respectively). The concentrations of milk trans C18:1 and vaccenic acid (VA) were higher (p<0.05) with the FOLSO diet (13.53 and 7.48% of total FA, respectively) than the CONT diet (3.69 and 2.27% of total FA, respectively). In conclusion, supplementing the diet of grazing cows with FO and LSO increased milk cis-9 trans-11 CLA content but reduced milk fat content and yield.

Purpose: To determine clinically useful biochemical markers reflecting disease activity and/or gastrointestinal (GI) tract involvement in Henoch-$Sch{\ddot{o}}nlein$ purpura (HSP). Methods: A total of 185 children with HSP and 130 controls were included. Laboratory data indicating inflammation, standard coagulation, and activated coagulation were analyzed for the HSP patients, including measurements of the hemoglobin level, white blood cell (WBC) count, absolute neutrophil count (ANC), platelet count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, prothrombin time, activated partial thromboplastin time, and fibrinogen, D-dimer, and fibrin degradation product (FDP) levels. The clinical scores of the skin, joints, abdomen, and kidneys were assessed during the acute and convalescence phases of HSP. Results: The WBC count, ANC, ESR, and CRP, fibrinogen, D-dimer, and FDP levels were significantly higher in the acute phase compared with the convalescent phase of HSP (p<0.05). The total clinical scores were more strongly correlated with the D-dimer (r=0.371, p<0.001) and FDP (r=0.369, p<0.001) levels than with inflammatory markers, such as the WBC count (r=0.241, p=0.001), ANC (r=0.261, p<0.001), and CRP (r=0.260, p<0.001) levels. The patients with GI symptoms had significantly higher ANC (median [interquartile range], 7,138.0 [4,446.4-9,470.0] vs. 5,534.1 [3,263.0-8,153.5], p<0.05) and CRP (0.49 [0.15-1.38] vs. 0.23 [0.01-0.67], p<0.05), D-dimer (2.63 [1.20-4.09] vs. 1.75 [0.62-3.39]), and FDP (7.10 [0.01-13.65] vs. 0.10 [0.01-7.90], p<0.05) levels than those without GI symptoms. Conclusion: D-dimer and FDPs are more strongly associated with disease activity and more consistently reflect GI involvement than inflammatory markers during the acute phase of HSP.

The hazardous effects of heavy alcohol intake and smoking to body systems have been identified by numerous studies, and there is many influencing factors on alcohol intake and smoking choices. The aim of this study is to identify the correlation between alcohol intake and digit ratio (2D:4D), as well as smoking and digit ratio (2D:4D) in university students. Participants were 121 male and 314 female university students. After filling in questionnaire related alcohol and smoking history, 2nd and 4th finger lengths were measured on both hands using vernier callipers with photocopy. This study showed 2D:4D of the males was 0.95, and that of the females was 0.96. There was a significant difference between male and female in digit ratio. The digit ratio according alcohol intake level significantly differed in only women's left hand. The digit ratio according smoking level significantly differed in only men's left hand. Moreover, The digit ratio was negatively associated with alcohol intake and smoking. The results of this study suggest that the digit ratio (2D:4D) affected with fetal testosterone concentration is negatively related to alcohol intake and smoking. Therefore, the digit ratio would be used in preventive program of alcohol intake and smoking of adolescent, or in antialcoholism /smoking cessation program as a biological basic data.

Statements of problem: Adequate bone quality and quantity were important to achieve initial stability and to prevent early failures. However there were few published data available regarding the actual effect of dimensional change in implant geometry on initial stability. Purpose: The purpose of the current study was to investigate the influence of diameter and length changes on initial stability of implants. Material and methods: Four types of dummy bone (D1, D2, D3 and D4) consisted of cortical and cancellous layers with different thickness were simulated. Implants which had similar surface area to each other ($3.5{\times}13.0-mm$, $4.0{\times}11.5-mm$, $4.5{\times}10.0-mm$, $5.0{\times}8.5-mm$) were inserted in dummy bones. Implant stability as a function of peak insertion torque and resonance frequency values were recorded for each implant. Results: 1. Bone quality was a major influential factor to achieve initial stability (P <.05). 2. In D1, D2 and D3 dummy bones, implant stability quotient values were not significantly different to each other (P >.05), however insertion torques were increased with wider and shorter implants (P <.05). 3. In D4 dummy bone, implant stability quotient values and insertion torques were decreased with wider and shorter implants (P <.05). Conclusion: From a point of view of initial stability, it is suggested that use of wide and short implant may be helpful in avoiding bone augmentation procedures in area of adequate bone quality.

Physiological accommodation in aphakia has been reported 0.50D. Also, accommodation appears in pseudo-crystalline lens. However accommodation was not clear how to works in the eyes. Therefore, the purpose of this study is that accommodation has been affected to changes of axial length and corneal refractive power when the accommodative stimulus was taken 10 diopters to person who has pseudo-crystalline lens. To determine of the accommodative response of pseudo-phakic patients who had no side effects over 2 months, we have measured the axial length, corneal refractive power in 48 patients(96 eyes). When the accommodative stimulus was taken about 10 diopters, the axial length increased by $0.05{\pm}0.06mm$ and corneal refractive power increased $0.04{\pm}0.24$ diopter. The changes of axial length in the myopia was increased by $0.19{\pm}0.18D$, emmetropia was increased by $0.12{\pm}0.16D$ and hyperopia was $0.10{\pm}0.19D$. The results of measurement revealed that the mean value was increased $0.03{\pm}0.13D$ in the myopia, and increased $0.21{\pm}0.13D$ in the emmetropia, and decreased $0.02{\pm}0.34D$ in the hyperopia.
