Objectives : As Daily Dose of Zizyphi Fructus was designated by the numbers in Treatise on Cold Damage Disease, estimation of Daily Dose was all different among researchers. The purpose of this study was to estimate exact Daily Dose of Zizyphi Fructus. Methods : We fixed the errors in various copy of Treatise on Cold Damage Disease and considered the meaning of the Bee Zizyphi Fructus(肥大棗) and general rules of Daily Dose in Treatise on Cold Damage Disease. So we reduced Daily Dose of Zizyphi Fructus, and compared this with the standard of Zizyphy Fructus in Pharmacopoeia of several Nation and Korean Forest Service. Results : Daily Dose of Zizyphi Fructus was generally 12 pieces; less was for prescriptions which scaled down the amount of ingredients prescribed in the originals; 15, 25, and 30 pieces were used when more was required. The medicinal part was the pulp of fructus, and the dosage of 12 pieces was respectively equivalent to 3 Ryang(兩), and 19.5 g. As defined in the Korean Pharmacopoeia Ninth Edition and standards of forest products by Korea Forest Service, Zizyphi Fructus was medium-sized, and weighs about 1.625 g if properly dehydrated. Conclusions : In short, the proper Daily Dose of Zizyphi Fructus in Treatise on Cold damage Disease was 12 pieces of Zizyphi Fructus and 19.5 g of its pulp, weighing three Ryang(兩). The pulp was estimated to be 1.625 g; it was medium-sized according to the present standard.

Final goal of periodontal treatment is to reconstruct the destructed periodontal tissue as well as to remove the necrotic pathologic elements. The purpose of this study is to investigate on the effect of Zizyphi extract to the inhibitory ability on collagenolytic activity of P gingivalis, biologic activity of gingival fibroblasts, and on the collagen and protein synthesis of gingival fibroblasts. Gingival fibroblast from giniva of first bicuspids from patient for orthodontic treatment were used and cultured. For the measurement of inhibitory ability of collagenolytic activity, crude enzyme was extracted and used on the basis of modified Ono's method. On the inhibition of collagenolytic enzyme from herbal extracts, collagenokit CLN-100 were used. The cellular activity of gingival fibroblast, were studied using MTT solution and measured optical density on 570mm by ELISA reader. To measure the effects on the ability of whole protein and collagen synthesis, cell membrane was destructed with ultrasonic grinder after culturing, centrifuged and counted by liquid scintilation counter. The inhibitory effects on producing of $IL-l{\beta}$ by monocyte, after promotion of producing $IL-l{\beta}$ by LPS, were compared with the mixture of herbal extracts and other drugs using thymocyte stimulation assay. About inhibitory effects of $PGF_2$. by gingival fibroblasts, herbal extract was compared with the addition of the other control groups using enzyme imunoassay. On the inhibition of collagenolytic activity by P. gingivalis, benzene extracts showed the most efficient inhibitory effects among the $19{\mu}g/ml$ of the compared extracts and 40.5% by Tetracycline. On the cellular activity promoting effects, compared extracts showed a bit of more effects than PDGF of $100{\mu}g/ml$ concentration and IGF of $20{\mu}g/ml$ concentration. All of the PDGF, IGF, Zizyphi Fructus extract should increase in collagen synthesis, but especially 70% ethylalcohol extracts of Zizyphi Fructus showed comparably high effects among the compared extracts. Effects on whole protein synthesis were slightly increased on every extract but especially 70% ethylalcohol extract showed significantly effective than any other estract. On the inhibitory effects of Zizyphi Fructus $IL-l{\beta}$ production by monocyte, compared extracts showed 70% of highly inhibitory effect than that of 60% inhibition effects on controlled group and each extracts showed no significant difference. In $PGF_2$ production inhibitroy effect of Zizyphi Fructus gingival fibroblasts, Herbal extracts showed 70% of inhibition comparing with tat of 90.2% of controlled group, but each extracts showed similar effects excluding the $H_2O$ extracts. These results suggested that Zizyphi Fructus might be useful medicine for inhibition of inflammatory mediator including $IL-l{\beta}$ and $PGF_2$.

The purpose of this study was to perform on the biological activity of Magnolia and Zizyphi fructus extract mixtures on the wound healing of defected rat calvaria. For the determination of the mixture ratio of two extracts for oral administration, preliminary experiments were performed with the mixture combination of 2000 and $3000{\mu}g/ml$ of Magnolia extract, and also 20, 30, 200, 300, 2000 and $3000{\mu}g/ml$ of Zizyphi fructus extract, respectively and divided into 6 groups. The combination of extracts mixture were tested on the enhancing effect of cellular activity. The effect of the extracts mixture on the cellular activity was evaluated using MTT method and measured on the results with optical density by ELISA reader. The ability to tissue regeneration of the extracts mixture was performed by measuring new bone and new connective tissue regeneration on the 5mm defected rat calvaria for 1, 2 and 3 weeks after oral administration of 2 different dosages groups : 10:1(0.1g/kg) and 10:1(0.5g/kg). It was employed the same dosages of unsaponifiable fraction of Zea Mays L as positive controls. Each group of rat was sacrificed and en bloc section for histological examination. The effect on the cellular activity of each mixture ratio showed significantly higher in $2000{\mu}g/ml$ of Magnolia extract and $200{\mu}g/ml$ of Zizyphi fructus extract group to compare with other groups. These preliminary results showed that appropriate mixture ratio of two extracts was 10:1 of Magnolia and Zizyphi fructus extract. Histological examination on the activity of tissue regeneration of each group showed that 2weeks and 3weeks specimens of 0.5g/kg of 10:1 extract mixture of Magnolia and Ziziphi fructus administrated rat calvaria revealed significantly more osteoid and new bone formation of defected calvaria with unification of defected area than the specimens of any other negative and positive controls. Even though the specimen administrated the same dosages of unsaponifiable fraction of Zea Mays L, positive controls, showed the trend that they promote significantly the repair of calvarial defect, their bone reparative activities were less inductive than the same dosages of Magnolia and Ziziphi fructus extract mixture. These results implicated that the mixture of Magnolia and Zizyphi fructus extracts should be highly effective on the wound healing of bony defected site and might have potential possibilities as an useful drug to promote periodontal tissue regeneration.

The influences of the extracts from Cinnamomi Cortex, Eucommiae Cortex, Puerariae Radix, Lycii Fructus, Zizyphi Fructus, Schisandrae Fructus, Mume Fructus, Chaenomelis Fructus on mycelial growth and aflatoxin $B_1$ production from Aspergillus parasiticus were analyzed. The pH of the culture media were reduced to below pH 4 by all the herbal extracts after 3 days incubation. However, the pH of the culture media increased above pH 6 after 6 days incubation using the extracts from Cinnamomi Cortex, Eucommiae Cortex, Puerariae Radix and Lycii Fructus. The mycelial growth of A. parasiticus was increased over the amount of the control. Puerariae Radix produced the largest amount of mycelial growth and Chaenomelis Fructus produced the smallest amount of mycelial growth. The productions of aflatoxin $B_1$ from A. parasticus culture were increased by the extracts of Puerariae Radix and Zizyphi Fructus, while inhibited by the extracts of Cinnamomi Cortex, Eucommiae Cortex, Lycii Fructus, Schisandrae Fructus, Mume Fructus and Chaenomelis Fructus. In particular, the extracts of Cinnamomi Cortex, Lycii Fructus and Schisandrae Fructus almost inhibited the production of aflatoxin $B_1$. The production of the total protein from Cinnamomi Cortex, which produced much less aflatoxin $B_1$, and Puerariae Radix, which produced a great deal of aflatoxin $B_1$ from A parasticus were slightly higher than the production of the total protein of the control medium.

In human intestine, more than 100 species of bacteria reside and dietary factors may alter the bacterial flora which produce bacterial enzymatic activities. Especially ${\beta}-glucuronidase$ and tryptophanase activities in colon are closely associated with occurrence of colon cancer. Therefore, the inhibitory effect of traditional herbal food extracts on these intestinal bacterial enzymes are measured. The results of this study showed that Zizyphi fructus and Glycyrrhiziae radix decreased not only ${\beta}-glucuronidase$ and tryptophanase productions of human intestinal bacteria but also inhibited potently ${\beta}-glucuronidase$ and tryptophanase. Among solvent-extracted fraction of tested herbal foods, ether fraction of Glycyrrhiziae radix and ethylacetate fraction of Zizyphi fructus inhibited potently ${\beta}-glucuronidase$ and tryptophanse. Thus, ethylacetate fraction of Zizyphi fructus separated six components by silica gel column chromatography. The component having Rf=0.34 and Rf=0.43 $(developing\;solvent,\;CHCl_3/MeOH\;(3:1))$ shwed the highest inhibitory effect of ${\beta}-glucuronidase$ and tryptophanase among them.

This experiment was performed to investigate whether 50% ethanol extracts of the combined-preparation of Longanae Arilus, Chrysanthemi Flos, Zizyphi Fructus and Ginseng Radix alba (CPE) has hypnotic effects and/or enhances pentobarbital-induced sleeping time. Locomotor activity was evaluated using a ambulometer of tilting-type. The sedative-hypnotic effects were evaluated by measuring the sleeping onset time and sleeping time in pentobarbital-treated mice 30 min. after oral administration of CPE and muscimol. The intracellular $Cl^-$ concentration of cerebellar granule cells was estimated using $Cl^-$ sensitive fluorescence probe N-(ethoxycarbonylmethyl)-6-methoxyquinolinium (MQAE). CPE (150 mg/kg) decreased the locomotor activity, but CPE itself did not induce sleep. However, CPE reduced sleeping onset and prolonged sleeping time induced by pentobarbital (42 mg/kg). In addition, CPE (2 ${\mu}g/ml$) and pentobarbital (2.5 ${\mu}M$) itself did not affect on the chloride influx in primary cultured cerebellar granule cells, but the combination of CPE and pentobarbital (2.5 ${\mu}M$) increased the chloride influx onto the cells. In conclusion, it is suggested that CPE might augment pentobarbital-induced sleep through the increase of chloride influx.

Two of the essential processes required for metastasis are neoangiogenesis and tumor cell invasion of basement membranes (BM) and extracellular matrix (ECM). Recently, data showed that herbs removing blood stasis has an anti-angiogenic effects. Tonifying vital Qi and eliminating pathogenic factor was a basic modality in Oriental oncology. In this study, we investigated several Qi and Blood tonics for potent angiogenic inhibitors. Methanol extracts of samples inhibited the proliferation of ECV-304 at the concentration of 100 ㎍/㎖. Zizyphi Fructus, Glycyrrhizae Radix, Angelicae Gigantis Radix decreased the gelatinolytic activity of MMP-9 from ECV-3Q4, at the concentration of 100 ㎍/㎖ in gelatin zymography. In in vitro invasion assay, herbs inhibited the invasion activity of ECV-304 by 53% of control (Ginseng Radix), 39% (Zizyphi Fructus), 36% (Angelicae Gigantis Radix), 25% (Glycyrrhizae Radix). Ginseng Radix inhibited the capillary-like tube formation of ECV-304 at the concentration of 160 ㎍/㎖, Angelicae Gigantis Radix and Paeoniae Radix Alba inhibited at the concentration of 320 ㎍/㎖. These results indicated that Ginseng Radix, Glycyrrhizae Radix, and Angelicae Gigantis Radix could be considered as potent angiogenic inhibitiors.
