To evaluate the diagnostic accuracy of the measurement of free thyroxine(FT4) by radioimmunoassay, we measured free T4 and T4, T3, T3RU, TSH and TBG serum levels by radioimmunoassay in 18 healthy persons and 52 patients with various thyroid diseases and 11 normal pregnant women. The results are as follows. 1) In 19 cases of overt hyperthyroidism, T3, free T4 and FTI, T4/TBG ratio reflect hyperfunction in all cases. T4 is increased in 94%(18/19) and TBG and TSH are decreased in 79%(15/19). 2) In 8 patients with overt hypothyroidism, TSH is increased in all cases and free T4 and FTI is decreased in all cases. T4 is decreased in 87.5%(7/8), T3 is decreased in 75%(6/8) and T4/TBG ratio is decreased in 62.5%(5/8). 3) In 5 patients who are clinically in euthyroid state after treatment of hyperthyroidism, T4 free T4, FTI and TSH are in the normal range in all cases and T3 is normal in 60%(3/5) and slightly increased in 40%(2/5). 4) In 10 patients who showed clinically borderline hypothyroidism after treatment of hyperthyroidism, TSH is increased in all cases and free T4 and FTI are decreased in all cases, but T4 and T3, T4/TBG ratio are in the normal limit in all cases. So after treatment of hyperthyroidism, TSH, free T4 or FTI are recommended as optimal function test. 5) In normal pregnancy, free T4, FTI and T4/TBG ratio reflect normal function, but the other parameters unreliable due to the influence of increased TBG. Also TBG and TSH level in pregnancy is increased significantly compared with normal healthy control group. 6) The coefficients of correlation between T4 and FTI were 0.862(p〈0.001) and 0.685(p〈0.001) between free T4 and T4/TBG ratio. In most patients, diagnostic value of free T4 was comparable and even superior to FTI, so free T4 measurement can be used routinely with thyrotropin assay in the diagnosis of hypothyrodism or with T3 for the diagnosis of hyperthyroidism.

This experiment was carried out to determine the growth characteristic, dry matter production, crude protein yield and palatability in intercropping and pure culture. The treatments were pure vulture$lt;Sorghum × Sudangrass hybrid(Tl), Soybean (T2)$gt; and intercropping culture [Sorghum × Sudangrass hybrid$lt;T3(1)$gt; + Soybean$lt;T3(2)$gt; = T3]. The experiment was performed at the College of Natural Science of Kon-Kuk University in Chungu from 1989 to 1991. The results obtained from these experiments are as follows ; 1. In plant length, leaf length and leaf width of the sorghum × sudangrass hybrid(S.S.H)' T3(1) was higher than T1 during the experimental period(1989-1991). Also, growth characteristics of soybeans had the same tendency. 2. In the soybean and S.S.H, the number of leaves of T3(1,2) was higher compared with T1 and T2, but in the stem hardness, T2 was harder than T3(2) and T3(1) was harder than T1 in S.S.H. 3. In T3, the leaf ratio of S.S.H decreased but that of soybeans increased. However resistance to lodging of S.S.H increased and soybeans decreased. 4. In T3, S.S.H showed an increase in the number of tillers, while rate of dead stubble decreased. 5. In the first cutting time, palatabilities were 100, 71, 21% on T2, T3 and T1, respectively. but at the 2nd and 3rd cutting time, there was no difference between TI and T3. 6. Dry matter production of T1 was the highest, but the extent of yield depression was highly increased according to the times of the year. While, in T3, it was slightly increased and the yield of three years was similar to pure T1(T1 : T3 = 15,202 : 14,977㎏/㏊). 7. In protein yield, T3 was higher than pure culture(T1, T2). 8. In the change in chemical characteristics of soil, T3 was higher than T1 in the pH, organic matter, avail. P₂O_5 and total nitrogen. T3 was better than T1 for soil improvement and maintenance

Growth characteristics and palatability by different harvesting dates were measured in order to determine its availability and effective storage period when sorghum × sudangrass hybrid were stored as foggage. Experiment was carried out with six treatments as follows; T1, T2 and T3 were foggaged at 120, 160 and 200㎝ in plant length and T4, T5 and T6 were foggaged at boot, milk and dough stage on 7 october after regrowth respectively. Rice straw was offered to examine the relative palatability a, control. 1. Growth characteristics such as plant length, leaf length, leaf width, leaf number and stem hardness were decreased with prolongation of foggage period at all treatments. Especially, decrease and falling ratio were a heigher at T5 and T6 than the other treatments. 2. Greeness grade of leaf showed fast decoloration at TI and T2 treatments, but stem showed fast decoloration at TS and T6 treatments. Leaf and stem decolorized in mid-October and mid-november in all treatments. 3. Leaf ratio was deceased with prolongation of foggage period, but stem showed gradually increase. Grain ratio was stable increase at T6 treatments, but not at T5 treatment, 4. Dry matter contents of leaf and grain were stable increased at all treatment but stem was multifarious according to weather conditions. 5. Changes of palatability were high at T1, T2 and T3 treatments untill mid-October, but T4 treatment and rice straw showed high in early December. 6. According to the results obtained in this study, it was suggested that when sorghum x sudangrass hybrid is used as foggage, foggaging period would be suitable until mid-november and growth stage for foggaging would be recommendable from T2 to boot stage for maximum availability.

This study was conducted to investigate the physico-chemical characteristics of various bone extracts in Hanwoo cattle. The experimental materials are as follows; T1(Shank bone extract), T2(Tail extract), T3(Beef feet extract), and T4(The other bones extract). In the proximate composition, the T1 and T2 showed higher moisture and fat contents than those of T3 and T4(p<0.05), and the T3 had the highest protein content among the bone extracts(p<0.05). The quality properties including salinity, sugar content, turbidity and yellowness(b*) values were significantly higher in the T3 than the other bone extracts(p<0.05). However, the pH value of T3 was significantly lower than the other bone extracts. In the mineral contents, calcium contents of bone extracts were 36.33-48.57mg/kg, and the content of phosphorus was the lowest in T1(4.62mg/kg) and T2(19.88mg/kg) was the highest(p<0.05). Contents of sodium and potassium were the highest in T3(215.83mg/kg) and T2(54.59mg/kg), while the content of magnesium was the lowest in T3(12.28mg/kg). In conclusion, these results could be suggested to be the basis information for processed meat extract products industry in korea using Hanwoo bone extract.

This study was conducted to assess the effects of organic and inorganic copper on performance in growing pigs. A total of 100 pigs, average age 63 d and initial body weight 21.46${\pm}$1.13 kg, were assigned to five treatment groups. Dietary treatments included i) CON (basal diet, 0 ppm Cu), ii) T1 (basal diet with 67 ppm Cu as cupric sulfate, $CuSO_4$), iii) T2 (basal diet with 134 ppm Cu as $CuSO_4$), iv) T3 (basal diet with 67 ppm Cu as cupric methionate, CuMet) and v) T4 (basal diet with 134 ppm Cu as CuMet). Throughout the entire experimental period, ADG (average daily gain), ADFI (average daily feed intake) and G/F (gain: feed) ratios showed no significant differences. The dry matter digestibility was improved in the T1, T2, T3, and T4 treatments (p<0.05), as compared with CON. Nitrogen digestibility was improved in the T3 treatment group as compared with CON (p<0.05). As compared with the T1 treatment group, fecal pH values were improved in the CON, T3, and T4 treatment groups (p<0.05). Fecal Cu concentrations were significantly lower in the CON, T3, and T4 treatment groups than in T1 and T2 (p<0.05). The incidence of diarrhea was reduced when the pigs were fed on the T2, T3, and T4 diets as compared with CON. In conclusion, diets supplemented with 67 or 134 ppm Cu as CuMet may prove effective in improving nutrient digestibility and fecal pH value in growing pigs, and fecal Cu concentrations may be reduced by CuMet supplementation.
