Effects of Alismatis water extract (AE) on the blood pressure were investigated in the rabbit and the dog. AE, when administered into the vein of rabbit and dog, into the lateral ventricle of rbbit, produced fall of blood pressure. The depressor response of the rabbits to intravenous AE was abolished by treatment with atropine, but not with chlorisondamine weakened the depressor effect of AE. Intravenous AE in this rabbit produced secondary elevation of the blood pressure. AE potentiated the pressor response of the rabbit to norepinephrine and tyramine, but nor to angiotensin, acetylcholine, and DMPP.

An HPLC analytical method was validated for the quantitative determination of biogenic amines in agricultural products. Four agricultural foods, including apple juice, Juk, corn oil and peanut butter, were selected as food matrices based on their water and fat contents (i.e., non-fatty liquid, non-fatty solid, fatty liquid and fatty solid, respectively). The precision, accuracy, recovery, limit of detection (LOD) and quantification (LOQ) were determined to test the validity of an HPLC procedure for the determination of biogenic amines, including tryptamine, ${\beta}$-phenylethylamine, putrescine, cadaverine, histamine, tyramine, spermidine and spermine, in each matrix. The LODs and LOQs for the biogenic amines were within the range of 0.01~0.10 mg/kg and 0.02~0.31 mg/kg, respectively. The relative standard deviation (RSD) of intraday for biogenic amine concentrations ranged from 1.86 to 5.95%, whereas the RSD of interday ranged from 2.08 to 5.96%. Of the matrices spiked with biogenic amines, corn oil with tyramine and Juk with putrescine exhibited the least accuracy of 84.85% and recovery rate of 89.63%, respectively, at the lowest concentration (10 mg/kg). Therefore, the validation results fulfilled AOAC criteria and recommendations. Subsequently, the method was applied to the analysis of biogenic amines in fermented agricultural products for a total dietary survey in Korea. Although the results revealed that Korean traditional soy sauce and Doenjang contained relatively high levels of histamine, the amounts are of no concern if these fermented agricultural products serve as condiments.

1. In the tortoise, Amyda japonica, a cold-blooded animal readily available in this country, the role of catecholamines in the regulation of free fatty acids(FFA) metabolism was investigated in both in vivo and in vitro studies. 2. Norepinephrine elevated both FFA and glucose levels in plasma. 3. When $50{\mu}g/kg$ of Epinephrine, Norepinephrine and Isopropylarterenol were administered intravenously, the relative effectiveness of mobilizing FFA was in the descending order of potency-Epinephrine, Norepinephrine and Isopropylarterenol. 4. In order to exclude the 'tonic influence of the endogenous catecholamines', reserpine was given to some animals. Two days after the reserpine-treatment, glucose showed a significant increase over the solely vehicle treated controls, FFA but an insignificant one. Excised auricles from those animals showed a diminished response to tyramine. Seven days after the treatment, however, when the depletion of catecholamines from the tissue stores seemed to be complete, judged from the absence of the response of isolated auricles to tyramine, both FFA and glucose levels were definitely lowered. 5. In in vitro experiments Epinephrine enhanced the FFA-release from the adipose tissue. The effect increased proportionately with the concentration until a maximal effect was attained at a concentration of 1x $10^5$ g/ml. 6. The order of potency in releasing FFA from adipose tissue in vitro was the same as in vitro, i.e., Epinephrine, Norepinephrine and Isopropylarterenol, but the differences were much less marked. 7. Ergotamine exerted no lipolytic action, but inhibited the lipolytic effect ef Epinephrine significantly. 8. Nethalide showed a slight lipolytic effect per se but inhibited the Epinephrine-induced lipolysis significantly. 9. Catecholamines play an important role in regulating FFA metabolism in the cold-blooded animal, just as in the warm-blooded animals, and the tortoise, Amyda japonica, may be used in the studies of fat metabolism as well as the rat.

Effect of noradrenaline and endothelium on the high K+ or Ach-induced contraction were investigated in the pig myocardial coronary artery. The helical strip of isolated pig myocardial coronary artery was immersed in the Tris-buffered Tyrode`s solution equilibrated with 100% O2 at 37oC and its isometric tension was measured. High K+ and Ach-induced contraction were dose-dependent. By denuding the endothelium, dose-contraction curve of K+ was not shifted significantly to the left and upward, but that of Ach was shifted significantly to same direction 25 mM K+ - and Ach-induced contraction were relaxed by norepinephrine[NE]. NE-induced relaxation was blocked by the pretreatment of propranolol, which was known as b-adrenoceptor blocker. And, phenylephrine known as a-adrenoceptor agonist, and clonidine known as a-adrenoceptor agonist increased the 25mM K+ - induced contraction respectively. Denuding of endothelium did not show any significant effects on NE-induced relaxation and contraction increased by phenylephrine and clonidine. Tyramine increased 25mM K+ - induced contraction further. The contractile response by tyramine on the 25mM K+ - induced contraction was not blocked by the pretreatment of phentolamine, but was partially blocked by the pretreatment of atropine. From the above results, it is suggested that activation of a1-and a2-adrenoceptors induce the contraction, activation of b-adrenoceptors induce the relaxation, and NE-induced relaxation is mainly due to activation of b-adrenoceptors. Also it is suggested that denudation of endothelium did not influence NE-induced relaxation, but influence Ach-induced contraction in the pig myocardial coronary artery.

In order to demonstrate whether ovoperoxidase hardens the zona of oocytes activated by incubating in M-S buffer supplemented with 20$\mu$M of Ca-ionophore A 23187, the effect of peroxidase inhibitors(250mM pheylhydrazine, 28mM sodilum sulfite, 350mM glycine ethyl ester and 50mM sodium azide), tyrosine analogue(12.5mM tyramine) and exogeneous peroxidase(50$\mu\textrm{g}$/ml horseradishperoxidase ; HRP) on zona hardening in ionorphore-treated oocytes were investigated. The results obtained from thses experiments were summarized as follows : 1. The zona solubility (t50) of ionophore-activated and DMSO-treated oocytes at 1, 2 and 3 hr of culture were 25.0, 31.6 and 40.6min., and 9.7, 10.8 and 15.5 min., respectively. The longest time required for zona lysis of ionophore activated oocytes at 1 hr after onset of ionophore treatment. The diferences int50 for zona was significantly greater as compared to DMSO-treated controls(P<0.01). 2. The inhibition rates of hardening in the oocytes treated with the phenylhydrazine, sodium sulfite, glycine ethyl ester and sodium azide, were 23.8, 61.9, 95.2 and 23.8%l, respectively, and the tyramine, was 14.3%. Several known peroxidase inhibitors and tyrosine analogue were blocked zona hardening in ionophore activated oocytes. 3. The treatment of exogeneous peroxidase promoted the zona hardening of activated oocytes but not unactivated oocytes. These resuls indicate that the ovoperoxidase apparently catalyzes the hardening of the zona following ionophore activation of mouse oocytes.

국내에서 시판 유통되고 있는 9개$(A{\sim}I)$의 간장제품 중의 biogenic amine(BA) 함량을 조사하였다. 시판 간장에서 검출된 biogenic amine은 putrescine, cadaverine, tryptamine, ${\beta}-phenylethylamine$, spermine, histamine 및 tyramine으로 총 7종류가 검출되었으며, 각 제품에 따라 그 종류 및 함량 차이를 나타내었다. PUT은 6 제품에서 가장 높은 수준으로 검출되었으며, 가장 높은 제품과 낮은 제품에서의 함량차이가 약 16 mg/kg이상으로 나타났다. 6개의 제품에서 7종류의 BA이 모두 검출 된데 반해 한 제품(I)에서 5종류의 BA만이 검출되었다. I 제품은 putrescine을 제외한 모든 BA에서 유의적으로 가장 낮은 함량 수준을 보였으며, B 제품의 경우 7종류의 BA이 모두 검출되었고 함량도 유의적으로 가장 높게 나타났다. 따라서 간장의 화학적 유해요소에 대한 안전성 확보를 위해 지속적인 함량조사를 포함한 다양한 저감화 연구 등이 필요하다.
