Percutaneous neurolysis of upper thoracic sympathetic ganglion was performed by simultaneously injecting 3 ml of pure alcohol into the $T_2$ and $T_3$ levels after testng with same amount of local anesthetics on the same sites. We experienced poor sympatholytic effect or intercostal neuritis and Horner's Syndrome as the result of complication of thoracic sympathetic ganglion block. In Case 1, in spite of the good testing result, neurolytic block effect was poor. In Case 2, intercostal neuritis occurred, but neuralgia subsided within 3 weeks. In Case 3, Horner's Syndrome occurred for 1 day. To increase the success rate of block and decrease the incidence of complications, good radio-opaque dye appearance and good test block effect should be obtained.

In this study the effect of alcohol extract of atractlis (AAE) on the blood pressure of the rabbit was investigated. The results of the experiment are as follows. AAE elicited hypotension with doses ranging from 3 to 30 mg/kg, i.v., exhibiting a linear dose-relationship. This effect of AAE was abolished by atropine and potentiated by physostigmine, while not affected by diphenhydramine, hexamethonium, propranolol and cyproheptadine. AAE did not influence the pressor responses to norepinephrine and the depressor to isoproterenol. The above results indicate that AAE produced the hypotension by stimulating the parasympathetic nervous system related to acetylcholine.

In our previous study, the crosslinked PVA/PAM membrane was prepared to investigate the pervaporation performance, and analyzed by FT-IR and water swelling test. This main objective of this work was to investigate the aging effect of PVA/PAM membrane with swelling time.(omitted)

Vinegar has been widely produced for a variety of industrial and domestic use as well as medicinal use. For sale of the commercial vinegar with herbal extracts, we produced an experimental black vinegar through sequential fermentation of alcohol, followed by acetic acid according to the manufacturer's procedure. To investigate the effect of anti-obesity of black vinegar on biochemical values, we evaluated enzyme activities via acetyl-CoA carboxylase (ACC), which plays a critical role in the lipid metabolism. We found that increased phosphorylated adenosine monophosphate (AMP) activated protein kinase (AMPK) and ACC in L6 mouse muscle cells treated with the manufactured vinegar. Based on the results, supplementation of experimental herbal black vinegar inactivates ACC, enhancing the phosphorylation of AMPK. Thus, the lipid oxidation and inhibitory effect of fatty acid synthesis by the black vinegar expects to facilitate the anti-obesity activity.

Researches on the drying of particle/polymer suspensions receive attentions in technical applications such as manufacturing display and batteries. In this study, the effect of polymers on drying behavior of silica/poly(vinyl alcohol) suspension was investigated in terms of suspension stability and stress development during drying. The effect of polymer adsorption was studied by changing pH. More strongly flocculated suspension with lower pH became more dispersed and close-packed film after drying. Evaluation of potential energy allows us to suggest that the adsorbed polymers which bridge the particles introduce steric repulsion and lead flocculated suspension to dispersed film. When the effect of adsorption kinetics was studied by changing the mixing time, the adsorption amount, characteristic stress and dried film density showed a similar behavior in the form of with a single characteristic time. It implies that the drying process can be determined by simple characteristic equation with a single time constant.

The present paper studies the effect of chitosan, cationic starch and polyvinyl alcohol (PVA) as sizing agents to enhance surface properties of kenaf paper. The polymers were incorporated into the sheets by spray application. The results clearly showed that the addition of chitosan to a sheet formed from beaten fibers had excellent improvement in surface properties, compared to the effect of other additives. Sizing quality of cationic starch fairly matched with the sizing quality of chitosan, however, it was able to reduce the water absorption potential of paper more than chitosan at a same concentration. In most other properties, particularly the most important property for printing papers, surface smoothness, chitosan-sized papers are superior to the paper sized with cationic starch or PVA.

The effect of ginseng saponin on chick embryonic dorsal root ganglia organ culture and brain, spinal cord, muscle dissociation cultures was studied. The fiber outgrowth in explanted chick embryonic dorsal root ganglia was markedly induced by water and alcohol extracts of ginseng, total ginseng saponin, protopanaxadiol and protopanaxatriol glycosides as well as ginsenosides R/sub b1/, R/sub d/, R/sub 0/+R/sub a/+R/sub b1/, and R/sub b2/+R/sub c/+R/sub e/ mixtures. The life span of the cultured chick embryonic dorsal root ganglia and potentiation of nerve cell density were also observed with all of these ginseng saponins. The effect of ginseng saponin on chick embryonic dorsal root ganglia organ culture was more marked in the absence of the chick embryonic extract which was known to contain nerve growth factor-like material in the culture media. However, the ginseng saponin did not influence the cultured central nervous system such as brain and spinal cord cells and cultured skeletal muscle cells with respect to the morphological changes, maturation and life span of these cells.

We have examined if lactic acid bacteria could suppress the toxic effect of bisphenol A. Lactobacillus casei YA-70 was chosen as representative. Thirty rats were divided into two groups (immature and mature) according to the weight. Each group was divided again into the control group (only alcohol treatment), bisphenol A treated group, and bisphenol A plus Lactobacillus casei YA-70 treated group. When 500 ppm of bisphenol A was fed everyday, 83% of immature group and 50% of mature group died within 3 weeks. Their internal organs, mainly livers and lungs, were changed in color and severely damaged. In the intestine of 5 ppm-fed group tumor-like nodules were observed. However, their number and size were markedly decreased when Lactobacillus casei YA-70 was supplemented in diet. This study strongly indicates that Lactobacillus casei YA-70 might play an important role to suppress the toxic effect of endocrine disruptor.

Four secondary metabolites from an unidentified tunicate were isolated by treatment with trichloroethyl chloroformate(TECF) or acetic anhydride in pyridine. Their structures were determined by an extensive NMR analysis and the configuration of diacetyl derivatives(3a, 4a) was assigned by comparing with NMR data of a similar compound. Three new naturally occurring compounds (1, 3, 4) showed potent brine shrimp lethality and antifungal effect against Candia albicans.
