An one percent sodium carbonate extract prepared from sclerotia of Poria cocos activated the proliferation of the T lymphocytes as measured by mixed lymphocyte responses(MLR). The active fraction, PCSC22, was isolated from an one percent sodium carbonate extract by a combination of fractionation procedures, including ethanol precipitation and chromatographies on column of DEAE-cellulose and Sephadex G50. Carbohydrate and peptide contained in PCSC22 were 78 : 22% in ratio. On employing gel filtration high performance liquid chromatography, PCSC22 exhitited a homogeneous peak with an average molecular weight of 8 kDa. The sugar moiety of PCSC22 was composed with mannose (92%), galactose (6.2%) and arabinose (1.3%), which might be indicated as heteromannan. Fifteen amino acids were found in peptide moiety of the polysaccharide and aspartic acid, serine, and valine were major components. PCSC22 activated the primary proliferation of T lymphocytes measured by mixed lymphocyte responses, the antibody production of the B lymphocytes and the secretion of nitric oxide from macrophage cell line, RAW264.7.

Objectives : The purpose of this study is evaluating the effect of Poria cocos pharmacopuncture (PCP) at $SP_6$(Sameumgyo) and $ST_{36}$(Joksamni) on chronic stress model(CSM) rats. Methods : The experimental rats were assigned to five groups: normal, CSM(control), PCP1X, PCP2.5X and PCP5X. The experimental rats in CSM(control), PCP1X, PCP2.5X and PCP5X were put through a timetable to cause CSM. PCP($20{\mu}l$) was administered at $SP_6$, $ST_{36}$ to groups PCP1X, PCP2.5X and PCP5X once every three days for a total of six times. The weight of the rats was measured by an electronic scale after PCP injection, once every three days for a total of six times. Blood samples were taken from the rats for analysis of aspartate aminotransferase(AST) and alanine aminotransferase(ALT). Serotonin and norepinephrine were measured by enzyme-linked immunosorbent assay(ELISA) kit. Results : The experimental groups(PCP1X, 2.5X, 5X) showed significant body weight increase compared to the control group. Regarding AST and ALT changes in serum, the experimental groups(PCP2.5X, 5X) showed a significant decrease compared to the control group. For Serotonin changes in serum, the experimental group(PCP5X) showed a significant increase compared to the control group. For Norepinephrine changes in serum, the experimental groups(PCP2.5X) showed a significant decrease compared to the control group. Conclusions : These data suggest that PCP at $SP_6$, $ST_{36}$ has therapeutic effects on CSM rats.

In this research, to modernize traditional food and to make functional bokryung-byung, bokryung-byungwas made with Poriacocos Wolf powder added. During its storage, its moisture content ranged from 42.89 to 44.85%. The control group had the highes tmoisture content (44.85%), and it was reduced significantly as the Poriacocos Wolf powder in creased. The longer the storage period was, the lower the pH and the higher the acidity was. The total bacterial count increased from 2.70 to 3.00 Log CFU/g right after the manufacture and increased rapidly on the fourth day of the storage with more than 7.00 Log CFU/g. There was no difference between the control group and the bokryung-byung, though. The Hunter's color value after the manufacture, with the increase in the added Poriacocos Wolf powder, showed a significantly reduced brightness, but significantly increased redness and yellowness. Their chromaticity did not change, how ever, during their storageat a temperature of $20^{\circ}C$. The hardness, solidity, gumminess, and cohesiveness of the bokryung-byung increased, unlike in the control group, and its brittleness increased. In terms of the overall preference, the preference for the control group was high, but was higher when 5 % Poria cocos Wolf powder was added during the manufacture of the bokryung-byung. As a result of these correlations, it is believed that elastic and chewy dduks are preferred and bokryung-byungs could be developed as functional dduks.

The nutritional quality and physiological activity of cultivated hoelen from 13 months to 24 months were examined to compare with natural hoelen. General compositions of hoelen were as follows re spectively; crude protein 1.80~2.50%, crude fat 0.68~1.23%, crude ash 0.12~0.43%, crude fiber 6.30~7.14%, nitrogen free extract 89.25~90.44%. The major free sugar was glucose, and the content of 13 months cultivated hoelen was higher than any other cultivated hoelen. The major fatty acids of hoelen were linoleic acid, palmitic acid, stearic acid and oleic acid. The ratio of unsaturated fatty acids was 62.62~77.96% and the content was higher in cultivated hoelen than in natural hoelen. The contents of amino acid were high in the order of tyrosine, aspartic acid, glutamic acid and serine, and increased as the day of cultivation became longer. The contents of mineral components were higher in the order of Ca, K, Mg and the contents of Na and Ca were higher in natural hoelen than in cultivated hoelen. The contents of pachymic acid and dehydropachymic acid was similar in the natural and cultivated hoelen. On the results of antimicrobial test the ethanol extract showed a stronger effect than water extract, and had an excellent antimicrobial activity on Micrococcus luteus and Escherichia coli. The ethanol extract of hoelen showed comparatively strong electron donating ability. The ethanol extract of hoelen showed a high inhibition activity on the growth of lung cancer, ovary cancer, skin cancer, central nerve cancer and rectum cancer, especially the activity of 19 months cultivated hoelen was the highest. On the above results of nutritional quality and physiological activity of hoelen, it is supposed that the picking date of cultivated hoelen was suitable over than 19 months.

This study was investigated to know whether pachymic acid (PA), one of the predominant triterpenoids in Poria cocos (Hoelen) has the sedative-hypnotic effects, and underlying mechanisms are mediated via ${\gamma}$-aminobutyric acid (GABA)-ergic systems. Oral administration of PA markedly suppressed locomotion activity in mice. This compound also prolonged sleeping time, and reduced sleep latency showing synergic effects with muscimol (0.2 mg/kg) in shortening sleep onset and enhancing sleep time induced by pentobarbital, both at the hypnotic (40 mg/kg) and sub-hypnotic (28 mg/kg) doses. Additionally, PA elevated intracellular chloride levels in hypothalamic primary cultured neuronal cells of rats. Moreover, Western blotting quantitative results showed that PA increased the amount of protein level expression of $GAD_{65/67}$ over a broader range of doses. PA increased ${\alpha}$- and ${\beta}$-subunits protein levels, but decreased ${\gamma}$-subunit protein levels in $GABA_A$ receptors. The present experiment provides evidence for the hypnotic effects as PA enhanced pentobarbital-induced sleeping behaviors via $GABA_A$-ergic mechanisms in rodents. Taken together, it is proposed that PA may be useful for the treatment of sleep disturbed subjects with insomnia.
