  • From February 1986 through September 1986, the authors have experienced 6 cases of coronary artery bypass graft for patients with unstable angina. There were five males and one female who ranged from 39 to 65 years [mean, 53.3 years]. The extent of coronary disease was as follows: one-, two- and three-vessel diseases, all 2 cases respectively, and among them, 1 case had left main disease. Distal anastomoses were performed first with using saphenous vein grafts as conduits in all cases and sequential bypass methods were employed in 5 cases. Numbers of vein grafts were two in 2 cases and one in 4 cases. The mean time wasted for one distal anastomosis was 36 minutes. Post operative complications were leg-wound disruption [2 cases], transient psychosis [1 case] and perioperative myocardial infarction [MI] [1 case]. Sixty three year-old male patient associated with cardiomegaly, prior MI, ventricular arrhythmia, cardiac dysfunction and endocrinologic diseases preoperatively was expired in the operating room due to perioperative Ml. All survivors were asymptomatic and on discontinuing medical therapy on follow-up varying from 1 to 8 months.

  • This study was conducted to find out the effects of estrogen and progesterone on body weight, uterine weight and serum prolactin levels on the growing female rats which were ovariectomized. For this purpose, 125 heads of rats (Wistar-Imamichi strain), 28 days old, were devided into 5 groups; OVariectomy(Ovx.), ovariectomy treated with estrogen(Ovx.+Est.), ovariectomy treated with progesterone(Ovx.+Prog.), ovariectomy treated with estrogen and progesterone(Ovx.+Est.+Prog.) and control group. Twenty-five heads of rats were arranged to each group, and changes of body weights were weekly checked. On the other hand, every 5 heads of rats in each group were sacrificed at 1, 2, 3, 4 and 5 weeks after treatments with time elapse for measuring concentrations of serum prolactin and for investigating the weights of ulterus. Prolactin concentrations in the serum were analyzed by radioimmunoassay. The results obtained are as follows; 1. The body weights were increased slightly in Ovx. in comparison with Ovx.+Prog., Ovx.+Est.+Prog., Ovx.+Est. and control groups, but there were not significant among the compared groups at all observation times. 2. The uterine weights in all treatment groups were decreased significantly (P<0.01) compared with control groups at all observation times. But the weights in Ovx. and Ovx.+Prog. groups were lower than those in Ovx.+Est. and Ovx.+Est.+Prog.. 3. Serum prolactin concentrations were increased slightly in control group in comparison with other groups at 1 and 2 weeks increased slightly in control group in comparison with other groups at 1 and 2 weeks after treatment. But compared with control group, the concentrations Ovx.+Est. and Ovx.+Est.+Prog. were high level, and those in other groups were low level in the order of Ovx. and Ovx.+Prog. groups at 3, 4 and 5 weeks after treatment. There were not significant among the compared groups at all observation times. 4. The results obtained in this study suggest that when ovariectomized rats receive 1$\mu$g estrogen and 3mg progesterone daily, that had no effect on body weight and serum prolactin concentrations while significantly effect on the weight of uterus.

  • This study was to select the measurement points of the girdle and the all-in-one. 15 subjects (age 30-40) were chosen by % body fat to represent various physical types. Subjects tried on each garment; a girdle and a all-in-one, in turns. Measurement points in the underwear were selected according to the parts of the human body. The characteristics and the surface area of the each garment were considered carefully when the measurement points were selected. Selected measurement points on the girdle and the all-in-one were chosen from the anterior midsagittal line, the side-seam line, and the posterior midsagittal line. Four points on the girdle and four points on the all-in-one were selected as the measurement points. There was highly significant correlation between % body fat and mean garment pressure. There was no significant relationship between thickness of subcutaneous fat and mean garment pressure by measured parts.

  • To investigate the effect of cereal powders on the quality and storage characteristics of sausage, Aw, pH, microbial count, TBA value, VBN value, textual and sensory characteristics were examined. Water activity tended to decrease as storage time prolonged and all the samples showed higher Aw's than that of the control. During the storage period, pH values of all the samples decreased. L, a and b values had a tendency to decrease during the storage period. During the four weeks storage at 4$^{\circ}C$, TBA and VBN values of all the sample showed increasing tendency and were lower than those of the control. Total plate counts of bacteria, the number of lactic acid bacteria and coliform bacteria counts increased as the storage time prolonged. Texture characteristics of all samples increased up to 1 week storage and decreased subsequently. The sensory scores of all the samples decreased as the storage time prolonged.

  • For a pointed space X, the subgroups of self-homotopy equivalences $Aut_{\sharp}_N(X)$, $Aut_{\Omega}(X)$, $Aut_*(X)$ and $Aut_{\Sigma}(X)$ are considered, where $Aut_{\sharp}_N(X)$ is the group of all self-homotopy classes f of X such that $f_{\sharp}=id\;:\;{\pi_i}(X){\rightarrow}{\pi_i}(X)$ for all $i{\leq}N{\leq}{\infty}$, $Aut_{\Omega}(X)$ is the group of all the above f such that ${\Omega}f=id;\;Aut_*(X)$ is the group of all self-homotopy classes g of X such that $g_*=id\;:\;H_i(X){\rightarrow}H_i(X)$ for all $i{\leq}{\infty}$, $Aut_{\Sigma}(X)$ is the group of all the above g such that ${\Sigma}g=id$. We will prove that $Aut_{\Omega}(X_1{\times}\cdots{\times}X_n)$ has two factorizations similar to those of $Aut_{\sharp}_N(X_1{\times}\cdots{\times}\;X_n)$ in reference [10], and that $Aut_{\Sigma}(X_1{\vee}\cdots{\vee}X_n)$, $Aut_*(X_1{\vee}\cdots{\vee}X_n)$ also have factorizations being dual to the former two cases respectively.

  • Sixteen somimembranosus muscles were seamed out from sixteen left carcasses. They were cut into $7{\times}10{\times}2cm$ pieces and mixed randomly. Samples were assigned to four treatments: (T1) soy-based sauce; (T2) Kimchi-based sauce; (T3) pickled shrimp-based sauce; and (T4) onion-based sauce. Each treatment was aged in plastic box at $1^{\circ}C$ for 10 days. These samples were vacuum-packaged after treatment with sauces and held in a chill at $1^{\circ}C$ for 28 days. The pH of aged port in general, was decreased significantly (p<0.05) with storage in all treatments. Its falling rate was the slowest in T4 of all treatments, while it was faster in T2 and T3 than in T4. The salinity of aged pork was decreased (p<0.05) for T2 with increased storage days, but increased (p<0.05) for T1. The salinity showed T2 to be significantly higher (p<0.05) than T1 and T4 on 1 day, but to be lower(p<0.05) than T1 on 28 day. The saccharinity of T3 was significantly higher (p<0.05) on 1 day than those of T1 and T4, but decreased (p<0.05) on 14 and 28 day. While saccharinity of T1 was significantly the lowest(p<0.05) of all treatments on 1 day and increased (p<0.05) with increased storage days. For T1 and T2, the WHC (water holding capacity) results showed higher (p<0.05) on 14 day than on 1 and 28 day. On 28 day, the WHC result showed T4 to be the highest(p<0.05) of all treatments, but T2 to be the lowest (p<0.05). On 28 day, the shear force results showed a big difference (p<0.05) among treatments, being in order of T4>T3>T2>T1. Panelists rated T1 as having higher(p<0.05) aroma, flavor and overall acceptability than other treatments.

  • This experiment was carried out to determine the effects of cutting frequency and nitrogen fertilization in the mixed pasture on root production and its depth distribution. The results are summarized as follows: 1. Root distribution studied on botanical composition was not significantly different by the upper 20cm level in all treatments. 2. Root yields were all high irrespectively of dominant species. However, Arrhenatherum elatius dominant pasture showed the lowest. Alopecurus pratensis dominant pasture showed the highest in root yield. 3. With the root yield, there was no significant difference in cutting frequency, but the moderate nitrogen level(N-2) showed the highest root yield among three N levels. 4. The depth distribution of root was 1m depth in all treatments.

  • Hypothyroidism was induced in three age groups (8 months, 1 year and 2 years) of Black Bengal goats by administering thiourea subcutaneously for 30 days. From fourth day onwards the animals were observed to be in hypothyroid state. For 8 months age group, a control group of similar age was taken. For the 1 year and 2 years age groups there was no control group but the values obtained on the pre-treatment day were considered as control values. For confirming the establishment of hypothyroidism, peripheral plasma triiodothyronine $(T_3)$ and thyroxine $(T_4)$ were estimated in all the animals before and during the treatment period by radioimunoassay. In the thiourea treated 8 months age group the $T_3$ and $T_4$ levels were significantly (p<0.001) lower than those in the control group during the treatment period. In all the thiourea treated groups the $T_3$ and $T_4$ levels observed during the treatment period were significantly (p<0.01) lower than the pre-treatment levels. A nonsignificant loss in the body weight was observed in all the thiourea treated groups whereas there was a significant growth in the control group of animals. The study indicates that hypothyroidism has a negative effect on growth in goats.
