The insurer's right to take legal proceedings in the name of the assured against a third party who has caused loss of or damage to the goods is of particular importance in marine cargo insurance under international trade transaction. The amounts recovered in subrogation actions, known in practice simply as recoveries, form a significant element in the balancing of the cargo insurer's underwriting account by improving ing the loss record. However, even if the carrier involved in the accident have a liability for damages, in some cases can not claim damages in accordance with the after clauses and carrier's exemption clauses indemnity carrier under the contract of carriage. In recent, the dispute cases to argue damages claim of the carrier in connection with business practices of surrender B/L, the claim is dismissed cases in accordance with the Arbitration Rules of the after clauses. In the future, the surrender B/L is continually to use as a marine transport method, it may also be interested in insurance subrogation of damages claims to insurance accident by a surrender B/L.

Two different molecular markers, the plastid rbcL and mitochondrial cox1 genes, were used to define the taxonomic position of the northwest Pacific Ocean species currently named Gracilaria chorda. We analyzed both genes (1,222 bp for rbcL and 1,245 bp for cox1) from 18 specimens collected in Korea, Japan, and China. Phylogenetic reconstruction revealed that this organism should be classified in the genus Gracilariopsis, rather than in the Gracilaria. Thus, Gracilariopsis chorda (Holmes) Ohmi is the legitimate name for Gracilaria chorda Holmes. Within the species, the sequences differed by 8 bp (0.7%) in rbcL and 5 bp (0.4%) in cox1. Six haplotypes of cox1 tended to be geographically organized. Gp. chorda is characterized by coarse, elongate terete axes, short filiform branchlets usually at irregular intervals, an abrupt transition in cell size from medulla to cortex, cystocarps without tubular nutritive cells connecting the gonimoblast to the upper pericarp, and relatively large gonimoblast cells of the cystocarp in the specimens collected from Wando in southern Korea.

The vasorelaxant actions and blood pressure lowering of the ${\alpha}_2$-adrenoceptor agonists (${\alpha}_2$-AAs) clonidine and xylazine were investigated in rat isolated aortic rings and anesthesized rats. Both clonidine and xylazine produced a concentration-dependent inhibition of the sustained contraction induced by norepinephrine (NE), but not by KCl. NE-induced contractions were attenuated partly by nifedipine or verapamil, voltage dependent $Ca^{2+}$ channel blockers. These $Ca^{2+}$ channel blockers-resistant contractions were abolished by clonidine or xylazine. Inhibitory effects of a ${\alpha}_2$-AAs on contractions could be reversed by ryanodine, an intracellular $Ca^{2+}$, transport blocker, and tetrabutylammonium (TBA), a $Ca^{2+}$ activated $K^+$ channel blocker, but not by nifedipine, glibenclamide or removal of extracellular $Ca^{2+}$ and endothelium. Moreover, ${\alpha}_2$-AAs produced relaxation in NE-precontracted isolated intact aortic rings in a concentration-dependent manner, but not in KCl-precontracted rings. The relaxant effects of ${\alpha}_2$-AAs were inhibited by ryanodine and TBA, but not by nifedipine, glibenclamide, N (G)-nitro-L-arginine (L-NNA), N(omega)-nitro-L-arginine methyl ester (L-NAME), aminoguanidine (AG), 2-nitro-4-carboxyphenyl N,N-diphenylcarhurnte (NCDC), lithium sulfate, staurosporine or removal of extracellular $Ca^{2+}$ and endothelium. In vivo, infusion of xylazine elicited significant decrease in anerial blood pressure. This xylazinelowered blood pressure was completely inhibited by the intravenous injection of TBA, but not by the intravenous injection of glibenclamide, L-NNA, L-NAME, AG, nifedipine, lithium sulfate or saponin.. These findings showed that the receptor-mediated and ${\alpha}_2$-adrenoceptor A-stimulated endothelium-independent vasorelaxant effect may be explained by decreasing intracellular $Ca^{2+}$ release and activation of $Ca^{2+}$-activated $K^+$ channels, which may contribute to the hypotensive effects of ${\alpha}_2$-AAs in rats.

The relaxation of gastric fundus smooth muscles is the primary physiological event which induces the receptive relaxation of monogastric animals. L-arginine/Nitric oxide(L-arg/NO) system is known to mediate the inhibitory non-adrenergic non-cholinergic(NANC) neurotransmission in various tissues including gastrointestinal smooth muscles. The longitudinal smooth muscles of porcine gastric fundus showed fast relaxation during electrical field stimulation(EFS) and rebound contraction after EFS in NANC condition. So, the purpose of present study was elucidation of the neurotrasmitters related to the NANC relaxation and explanation of the relation between NANC relaxation and L-arg/NO system. The longitdinal smooth muscles of porcine gastric fundus were hung in the organ bath and under the presence of guanethidine($5{\times}10^{-5}M$), precontraction was induced by carbachol($1{\times}10^{-6}M$). The muscle responses to EFS and drugs were isomerically recorded. The rusults were summarized as follows. 1. The longtudinal muscles of porcine gastric fundus showed frequency-dependent relaxation and rebound contraction to electrical field stimulaton(1ms, 8V, 1~16Hz, 20sec, EFS). These responses were blocked by tetrodotoxin($1{\times}10^{-6}M$). 2. The relaxation and rebound contraction of the longitudinal muscles of porcine gastric fundus to EFS were inhibited by L-NAME($2{\times}10^{-5}M$). The inhibitory effect of L-NAME was antagonized by L-arginine($1{\times}10^{-3}M$), but not by D-arginine($1{\times}10^{-3}M$). 3. Exogenous NO($NaNO_2$, $1{\times}10^{-5}{\sim}1{\times}10^{-4}M$, pH=2.0) caused concentration-dependent relaxation as EFS did. 4. Methylene Blue($2{\times}10^{-5}M$), a soluble guanylate cyclase inhibitor, inhibited the relaxation and rebound contraction of the longitudinal muscles of porcine gastric fundus induced by EFS, but N-ethlmaleimide, a adenylate cyclase inhibitor, did not. 5. 8-Br-cGMP($1{\times}10^{-6}{\sim}3{\times}10^{-6}M$), permeable cGMP analogue, induced dose-dependent relaxation. but 8-Br-cAMP($1{\times}10^{-6}{\sim}3{\times}10^{-6}M$), permeable cAMP analogue, did not. Both did not evoked rebound contraction. 6. ${\alpha}$-chymotrypsin did not affect the relaxation of the longitudinal muscles of porcine gastric fundus. 7. Reactive blue 2($1{\times}10^{-4}M$, 40min) siginificantly inhibited the rebound contraction induced by EFS and inhibited contraction caused by exogenous ATP($1{\times}10^{-4}{\sim}1{\times}10^{-3}M$). These results suggests that NANC relaxation of the longitudinal muscles of porcine gastric fundus mainly mediated by NO and the rebound contraction is related to NO and other neurotransmitters.

Backgrounds & Objectives: Banhasasimtang granule(BHSST) has been used for the treatment of functional dyspepsia regarded as one of the gastric dysmotility disease. but its mechanisms of action are not well known yet: So we investigated the effects of BHSST on gastric emptying and its mechanisms of action in rats. Methods: Gastric emptying was measured by glass beads(1mm in diameter) expelled from the stomach for 60 min after administration of normal saline(NS) or BHSST 31mg/kg or 93mg/kg in rats. And by the same method gastric emptying was measured after administration of NS or BHSST 93mg/kg in rats treated with atropine sulfate(1mg/kg, s.c.), quinpirol HCI(0.3mg/kg, i.p.), NAME(NG-nitro-L-arginine methyl ester, 75mg/kg, s.c.) or cisplatin(10mg/kg, i.p.) to make delayed gastric emptying. Results: BHSST 93mg/kg improved gastric emptying more than NS or BHSST 31mg/kg(p=0.016). Under the delayed gastric emptying, BHSST 93mg/kg improved gastric emptying in the group treated with NAME$(5.00{\pm}3.101\;vs\;9.00{\pm}3.51,\;p\;=0.046)$, but aggravated it With atropine sulfate$(5.71{\pm}3.45\;vs\;2.57{\pm}1.62,\;p\;=0.050)$ and cisplatin$(12.7{\pm}2.29\;vs\;8.57{\pm}5.06,\;p\;=0.072)$. Conclusions: BHSST improves the gastric emptying through cholinergic and 5-hydroxytryptamine 3 receptors. Especially it is effective to improve gastric emptying delayed by NAME. So we expect that it would be effective in functional dyspepsia with impaired reservoir functions such as gastric adaptive relaxation.

This work intends to study some problems in relation to the issuance of letters of credit. Those problems are the delay of issuing letters of credit, the reissuing letters of credit, and the issuing letters of credit in the third party's name. Sellers and buyers must keep in mind that the supply of letter of credit by buyer is the condition precedent for a seller's shipment obligation. A seller has no obligation to ship the goods until he receives the letter of credit by buyer's bank, issuing bank. An issuing bank can have the risk that an original letter of credit and a reissued letter of credit can be used double in the exporting country. The most safe method for issuing bank is to cancel the original letter of credit and to reissue a new letter of credit. When an issuing bank issues a letter of credit in the third party's name, the bank should investigate the background of the transaction and give the buyer a proper line of credit.

Nitric oxide (NO) has been regarded as one of the neurotransmitters of nonadrenergic, noncholinergic (NANC) nerve stimulation in rabbit corpus cavernosum, rat gastric fundus and human intestine. PIANO (photo-induced adequate nitric oxide) is a very useful tool to investige the role of NO in various smooth muscles where NO is a mediator. The present study was undertaken to compare the physiological responses of the rat gastric smooth muscle in response to NANC nerve stimulation and to PIANO. Photolysis of L-NAME, D-NAME and streptozotocin (572) by UV light in the bathing medium caused relaxation of rat gastric fungus that contracted with carbachol, but was resistant to tetrodotoxin (TTX, 1 $\mu$M). Electrical stimulation (20 V, 2~32 Hz, 0.2 msec, 10s) of the gastric fundus, in the presence of atropine and guanethidine, induced frequency-dependent, TTX-sensitive relaxation. Sodium nitroprusside (1 nM-10 $\mu$M), a NO donor, mimicked the relaxations observed after NANC-stimulation or PIANO. Furthermore, PIANO caused UV light exposure time-dependent increase of CGMP in rat gastric fungus strips. These results provide another evidence indirectly that NO is one of the mediators of the NANC inhibitory nerve stimulation in the rat gastric fundus.

It had been known for a while that Crataegi Fructus(CF; Crataegus pinnatifida Bunge) had only a digestive effect. Recently, it has been demonstrated that CF also has an anti-hypertensive effect. However, its mechanism of relaxant effect has not been investigated yet. This study was examined to investigate the mechanism of vascular relaxation effect of CF in isolated rat thoracic aorta. CF revealed significant relaxation to phenylephrine(PE)-induced arterial contraction but much less to KCI-induced one. When CF was pretreated, it inhibited PE-induced contraction non-competitively. Methylene blue(10/sup -6/M) completely blocked the relaxant effect of CF whereas L-NAME(10/sup -5/M) did almost completely. However, atropine(10/sup -6/M) did not have any influence on vascular relaxation effect of CF. Regarding cNOS activity, CF significantly increased its activity from rat whole brain homogenate in a dose dependent manner which was inhibited by L-NAME(10/sup -5/M). On the other hand, CF did not affect on expression of TNF-α mRNA in RAW 264.7 cells, suggesting that CF is not related to iNOS activity. These results indicate that CF would be effective in relaxing vascular contraction through release of endothelial nitric oxide.
