[$^{2}$H$_{2}$] Tranylcypromine hydrochloride (trans-3, 3-dideuterio-2-phenylcyclopropylamine HCL) was synthesized for application to the metabolic studies. Mass fragmentation processes for the tranylcypromine and its two synthetic intermediates .gamma-phenyl-.gamma.-butyrolactone and trans-2-phenylcyclopropanecarboxylic acid were described based upon comparisons between labeled and unlabeled compounds.

Tissue factor (TF), a principal initiator of the veertebrate coagulation cascade, is expressed in organ tissues, cells and blood. TF is konwn to be induced in endothelial cells, monocytes and macrophages by inflammatory stimuli and in many pathologic conditions. By using the modified method for in vido TF activity assay, we found that turpentine oil injection as an inflamatory stimulus also induced the TF activity in lung and brain tissues of rats. And the age-related increase in Tf activity was observed in healthy rat brain tissue.

Three phenolic compounds, rosmarinic acid (1), methyl rosmarinate (2), ethyl rosmarinate (3), and two flavonoids, luteolin (4), luteolin-7-O-$\beta$-D-glucuronide methyl ester (5) were isolated from the aerial part of Lycopus lucidus (Labiatae). Their structures were determined by chemical and spectral analysis. Compounds 1-5 exhibited potent antioxidative activity on the NBT superoxide scavenging assay. The $IC_{50}$ values for compounds 1-5 were 2.59, 1.42, 0.78, 2.83, and 3.05 $\mu\textrm{g}$/mL respectively. In addition, five compounds were isolated from this plant for the first time.

In the course of continuous work on the leaves of Allium tuberosum (Liliaceae), compounds 1 and 2 were isolated from the ethylacetate and butanol-soluble fraction, and identified as N-p-coumaroyl tyramine and bis(p-hydroxyphenyl) ether, respectively, on the basis of spectral data and physicochemical results.

Four compounds were isolated from Salicornia herbacea by repeated column chromatography. Their structures were identified as ${\beta}$-sitosterol (1), stigmasterol (2), uracil (3), and isorhamnetin-3-O-${\beta}$-D-glucopyranoside (4) by spectral analysis and comparison with the published data.

Oxidation of presenegenin dimethyl ester triacetate with chromium trioxide in acetic acid yielded two compounds, 11-ketone (IV) and 12-ketone (IV) derivatives. The latter was a main product. On mild alkaline hydrolysis, IV afforded 11-keto-presenegenin dimethyl ester (V), mp 232-$234^{\circ}$, $C_{32}H_{48}O_{8}$, whereas VI did 12-keto-presenegenin dimethyl ester 12, 27-hemiketal (VIII), mp 240-$242^{\circ}$, $C_{32}H_{50}O_{8}$.

Potential antinumor activity of sixteen Korean medicinal plants was tested against leukemia SN 36, murine tomor model. Survival studies by measuring life span indicated that Morus alba (Moraceae), Verbascum phlomoides (Scrophulariaceae), Curcuma longa (Zingbieraceae), Torilis japonica (Umbelliferae), Bupleurum falcatum (Umbelliferae) and Codonopsis pilosula (Campanulaceae) exhibited significant antitumor activity with the dose-schedule employed in the experiment. Methanol (70%) extracts of Platycodon gradiflorum (Campanulaceae), Bupleurum longeradiatum (Umbelliferae) and Asiasarum sieboldii (Aristolochiaceae) showed rather potent toxicity.

Effects of squalene on humoral immune system in mice were investigated. Squalene exhibited significant increases in the circulating leukocyte counts and relative spleen and thymus weights of the mice. However, the relative liver weight was slightly decreased. Hemagglutination titers (HA) were signficantly enhanced by squalene while Arthus reaction was not affected. Splenic plaque forming cells (PFC) were also greatly increased by squalene, especially at doses of 50 and 100 mg/kg of it.

Dopaminergic influences on prolactin release from lactotrophs have been studied using the rat anterior pituitary cell culture. The prolactin inhibiting activity of hypothalamic extracts was examined in relation to dopamine. Dopamine inhibited prolactin secretion from the rat anterior pituitary cell culture in a dose dependent fashion. The median effective dose was $2{\times}10^{-7}$ / M and the maximal inhibition (70-90 % of the control value) was shown by 10$^{-5}$ / M dopamine. Further increase in dopamine concentration did not result in any further inhibition of prolactin secretion.nhibition of prolactin secretion.
