The compositions of amino acid in the protein and total fatty acid of Dendrolimus spectabilis were analyzed quantitatively by HPLC and GC, respectively. The contents of crude oil and protein from the extracts were 21.00% and 58.47%, respectively. The amount of free amino acids in the protein was 3.65g/100g, and 1.31g/100g of essential amino acids was contained in the free amino acids. The amount of total amino acids in the protein was 41.20g/100g, and 14.75g/100g of essential amino acids were contained in the total amino acid. The compositions of fatty acid in the oil were $C_{18}$=26.81%, $C_{16}$=19.09%, $C_{18:1}$=18.74%, $C_{18:3}$=15.33%, $C_{16:1}$=7.29%, $C_{20}$=5.21% in order, respectively. 45.88% of unsaturated fatty acids were contained in the oil.

The aim of this study was to examine the effects of Capsosiphon fulvescens extract (CFE) on levels of essential amino acids in serum and the rate of protein digestion. CFE contains approximately 68% carbohydrate as fiber, 17% crude ash, and 14% crude protein. Experimental rats were divided two groups, one group receiving a normal diet and the other a normal diet containing 5% CFE. To analyze the absorption of essential amino acids into the hepatic portal vein, blood from the hepatic portal vein was collected between 10 a.m. and 5 p.m. for 10 days. In vitro protein digestion was decreased in the group fed 5% CFE; these data indicated that CFE affected protease activity. We measured the absorption of essential amino acids in the serum of the hepatic portal vein, at 30-, 60-, 90-, and 120 minutes after feeding. Although there was no difference in the concentration of total essential amino acids between the two groups, the 5% CFE-fed animals had a decreased rate of absorption. Absorption of Lys and Thr into the hepatic portal vein was lower in the CFE-fed group than in the control group. The rate of absorption of Met was delayed nearly 50% in the CFE-fed group compared to the control group. On the other hand, the rate of absorption of Leu, Ile, and Val was increased; Phe showed the same. Therefore, we suggest that CFE could affect protein metabolism by increasing or decreasing the absorption rate of essential amino acids.

This study was conducted to investigate the effect of essential amino acid(EAA) deficient diets on short-term feeding response and the Fos expression in brain area when methionine deficiency diet fed, and thereby to know the mechanism of feed intake regulation. In all trials, experimental diets were formulated with pure amino acid mixture to level of 15% nitrogen. Rats were adapted to a 6-hr single-meal feeding per day(17:00${\sim}$21:00). Feed intake and body weight were monitored every hour after 7-day of feeding of individual EAA deficient diets in Exp. Ⅰ. In Exp. Ⅱ, Fos immuno- histochemistry was determined in various regions of brain to identify the regions that is related to suppressed feed intake following feeding methionine-deficient diet. Fos expression was examined to know the initial sensitive region in the brains of rats at 3h after feeding of the control and methionine deficient diet(-Met). Initial response to EAA deficiency diets was severely depressed in methionine deficiency diet, but the depression was low in threonine deficiency diet. However, the feed intake at 3rd day in rats was depressed in the order of His(71%), Leu(68%), Ile(66%), Thr(63%), Trp(61%), Val(55%), Phe(52%), Met(51%), Lys(44%) and Arg(24%). Fos immunoreaction in neural regions(PPC, amygdala and EPC) of pyrifrom cortex was increased in the -Met group more than in the control diet group, but those in LH, VMH and PVM were similar. Thus, based on these data, the PPC was identified as the initial response area in the -EAA diet.

This study investigated the seasonal changes of body composition and elasticity between wild and cultured brown croaker, Miichthys miiuy. The wild fish were analyzed and compared with cultured fish in moisture, crude protein, lipid, ash and many kinds of amino acids. Cultured fish was higher in moisture content and lower in crude lipid and protein content than those of wild one. The wild fish were more abundant in the total amino acid compositions than those of cultured one. As result E/A ratio there was a little significant differences between wild and cultured. In highly unsaturated fatty acid, EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) content of cultured fish were higher than wild one. On the other hand, the gel strength, max weight and hardness of wild fish were higher than cultured one.

Free and total amino acids of Korean hazel nut (Corylus heterophylla Fisch. var. Japonica koidz.) were identified by amino acid autoanalyzer (Technicon PNC-1 type). The results indicate that among 16 kinds of all free amino acids contained in hazel nut, arginine was the richest, and then came glutamic acid, proline, alanine, tyrosine and valine in that order. From the total amino acids which were closely related with the nutritional valuation, arginine was in the richest amount and then came with glutamic acid, proline, leucine, aspartic acid and valine.
