It is noted that Streptococcus mutans (S. mutans) triggers dental caries establishment by two major factors: the synthesis of organic acids, which demineralize dental enamel, and the synthesis of glucans, which mediate the attachment of bacteria to the tooth surface. Therefore, it is noted that the development of a more effective, substantial and safe preventive agent that works against dental caries and periodontal disease is required at this time. For this reason, the present study was designed to investigate the effect of croton seed ethanol extracts on the growth, acid production, adhesion, and insoluble glucan synthesis of S. mutans. In this case, the ethanol extract of croton seed showed concentration dependent inhibitory activity against the growth, acid production and adhesion of S. mutans. Especially, it is important to note that it has produced significant inhibition at the concentration of 0.1 and 0.2 mg/ml as compared to the control group. Moreover, these results suggest that the application of croton seed extract may be considered to be a useful method for the prevention of dental caries.

The untreated leprosy skin takes on a waxy appearance & feel full. Thickening is most marked over the face, which starts to devolp into folds, hanging down to produce the classical lion-like facies. The deep folds in disease state change to the numerous compacted shallow wrinkle with less elasticity of the skin. To correct these wrinkles of the patients healed from the leprosy, we tried the stone-VK formula application to the 14 patients, who are men 10 & women 4 in the age distribution of 55~78 years old. The use of the phenol & croton oil chemical peeling this method is more effective than other chemical & conventional surgical method to remove facial wrinkle. We need more experience of this peeling. In preliminaxy report, our superior results in removing facial wrinkle is presented.

BACKGROUND: Langerhans cells (LC), keratinocytes and Thy-1+ dendritic epidermal cells(DEC) are epidermal cells which are known to have important roles in inflammatory or immunologic skin disorders. Allergic contact dermatitis(ACD) is a prototype of a delayed hypersensitive reaction in which LC, keratinocytes and T lymphocytes play an important role. The role of LC in ACD is well known, but the role of Thy-1+ DEC is not yet fully revealed. Futhermore, the mechanism of irritant contact dermatitis(ICD) is not known and more study is required on the interaction between these epidermal cells in ICD. OBJECTIVE: The aim of this study is to observe the changes of these cells in ACD and ICD and to discuss their possible roles in the disease precess. MEHTODS: We evoked ACD with DNFB and ICD with croton oil in BALB/c mice and observed the morphologic changes of LC, Ia+ keratinocytes, and Thy-1+ DEC by immunoperoxidase staining when the inflammation was at its peak and at the resolution state. RESULTS: 1. In the control group, LC were evenly distributed and their average number was 1147+/-132/mm*. Thy-1+ DEC were slightly bigger than LC and showed uneven distribution. The average number of Thy-1+ DEC was 57+/-69/mm* Ia+ keratinocytes did not appeared. 2. On the 1st day of DNFB challenge, the number of LC was significantly decreased and their size and dendritic processes were increased when compared to those of the control group. Most of the keratinocytes showed Ia antigen expression on their surfaces. 3. On the 12th day of DNFB challenge, no significant changes in the number and morphologyof LC were noted when compared to the cotrol group, Ia+ keratinocytes were not observed. 4. there were no significant changes in the number and morphology of Thy-1+ DEC in ACD on the 1st and 12th day after DNFB challenge. 5. On the 2nd day after croton oil application, the number of LC was significantly decreased but the morphology not significantly changed. Ia+ keratinocytes were not observed. 6. On the 20th day after croton oil application, the number of LC was significantly increased but the morphology was not significantly changed. Ia+ keratinocytes were not observed. 7. There were no significant changes in th number and morphology of Thy-1+ DEC in ICD on the 2nd and 20th day after application of croton oil. Ia+ keratinocytes were not observed. CONCLUSION: In can be deduced that the LC have important roles in the mechanisms of both ACD and ICD reactions. Ia+ keratinocytes have an important role mainlyin the inflammatory precess of ACD. In addition, since the changes of the number of Langerhans cells in ACD and ICD showed different time courses and Ia+ keratinocytes appeared only in ACD, we hypothesized that different pathways of inflammation exist in ACD and ICD, and different cytokines may be responsible. It is probable that Thy-1+ DEC does not have any significant role in the inflammatory process of both ACD and ICD.

This experiment was performed to evaluate the morphological responses of the rectal intestinal glands of the mouse, inoculated with Ehrlich carcinoma cells, following administration of adriamycin or composition of the extracts of the Croton tiglium and Coptis chinensis rhizome (CP-2, Institute of Experimental Tumor Research, Seoul, Korea). Healthy adult ICR mice weighing 25 gm each were divided into normal and experimental groups (tumor control group, adriamycin treated group, and CP-2 treated group). In the experimental groups, each mouse was inoculated with 1 x 10(7) Ehrlich carcinoma cells subcutaneously in the inguinal area. From next day, 0.2 mL of saline, adriamycin (2 mg/kg) or CP-2 (30 mg/kg) were injected subcutaneously to the animals every other day, respectively. The day following the 7th injection of anticancer drugs, each mouse was injected with a single dose of 0.7 microCi/gm of methyl- 3H-thymidine through tail vein. Seventy minutes after the thymidine injection, animals were sacrificed. and rectal tissues were collected and fixed in 10% neutral formalin. Deparaffinized sections were coated with autoradiographic emulsion EM-1 (Amersham Lab., England) in the dark room and dried. The number of the labeled epithelial cells of the rectal crypts (mean number of labeled epithelial cells per 3.5 mm length of mucosa) were observed and calculated. On histological study, in the rectum of adriamycin treated groups, length of the intestinal crypts is shorter than those of the normal control ones. Disrupted intestinal crypts and epithelial cells were observed. But in the CP-2 treated group, morphological changes of the rectum were not observed. On autoradiographic study, number of the labeled cells of normal control, rumor control, adriamycin-treated, CP-2-treated groups were 263.1 (+/-38.65), 395.7 (+/-52.52), 73.3 (+/-22.54), 96.3 (+/-28.36), respectively. In the adriamycin and CP-2 treated groups., poorly-labeled cells containing only a few silver grains of 3H-thymidine were observed more frequently than in those of the normal and tumor control groups. But in the tumor control group, number of the heavy labeled cells were observed more frequently than in those of the normal control group. From the above results, adriamycin and CP-2 may suppress the DNA synthesis of the cells of the rectal crypts. But CP-2 does not result any histological defect on the rectal mucosa. These results suggest that CP-2 is expected as one of most effective anticancer drugs.

OBJECTIVETo study the effect of dragon's blood powder with different grain size on the transdermal permeability and adhesion of ZJHX paste.

METHODDragon's blood powder with grain sizes of 4, 19, 55 microm were got by ultrafine grinding technology, and then prepared into rubber pastes A, B, C and D, together with dragon's blood powder with grain size of 93 microm of original description. Franz diffusion cell method was adopted to compare the difference in transdermal permeability of dragon's blood powder with different grain sizes, with dracorhodin as the index, and compared their effect on the adhesion of pastes with initial adhesion, permanent adhesion and peel strength as the indexes.

RESULTQ(s)-t equations of pastes A, B, C, D were as follows: Q(s)=1.369 6t + 3.985 5, Q(s) = 1.262 8t +3.738 1, Q(s) = 1.192 3t + 3.320 6, Q(s) = 1.152 2t + 2.366 1, respectively, which showed that the adhesion of A was the best good.

CONCLUSIONWith the decrease in the grain size of dragon's blood powder, accumulative penetration of dracorhodin increases, which facilitates transdermal permeability and adhesion.

Based on the toxic characteristics caused by the compatibility between "Zaoji Suiyuan" and Glycyrrhizae Radix et Rhizoma, which was found in the previous studies, the expanded study was carried out on the incompatibility mechanism between Crotonis Semen Pulveratum(CT) and Glycyrrhizae Radix et Rhizoma(GU) with the diuretic effect and intestinal flora as the characteristic indexes. The results showed that GU could slow down the rapid diuretic effect of CT, which suggested a tendency of decreasing the efficacy. Both the high and low dose of CT could significantly induce the intestinal injury and change the intestinal bacteria structure of mice. Low dose CT combined with GU could significantly increase the levels of Streptococcus and Rikenellaceae＿ukn. The relative abundance of Desulfovibrio and Streptococcaceae＿ukn were increased after the combined application of high dose CT and GU. It also suggested that there was a risk of inflammation in the liver and intestines when combined application of these two herbs. The results revealed that the combination of CT and GU has a tendency to reduce the clinical effect and increase the toxicity from the aspects of its traditional efficacy and its effect on intestinal microflora structure, which could provide the data for the clinical use of CT.

BACKGROUND: Glucocorticoids are effective anti-inflammatory drugs widely used in dermatology and for the treatment of blood cancer patients. Unfortunately, chronic treatment with glucocorticoids results in serious metabolic and atrophogenic adverse effects including skin atrophy. Glucocorticoids act via the glucocorticoid receptor (GR), a transcription factor that causes either gene transactivation (TA) or transrepression (TR). Compound A (CpdA), a novel non-steroidal GR ligand, does not promote GR dimerization and TA, retains anti-inflammatory potential but induces fewer metabolic side effects compared to classical glucocorticoids when used systemically. As topical effects of CpdA have not been well studied, this work goal was to compare the anti-inflammatory and side effects of topical CpdA and glucocorticoids and to assess their effect on GR TA and TR in keratinocytes. METHODS: We used murine immortalized keratinocytes and F1 C57BlxDBA mice. Effect of glucocorticoid fluocinolone acetonide (FA) and CpdA on gene expression in keratinocytes in vitro and in vivo was evaluated by reverse transcription-PCR. The anti-inflammatory effects were assessed in the model of tumor promoter 12-O-tertradecanoyl-acetate (TPA)-induced dermatitis and in croton oil-induced ear edema test. Skin atrophy was assessed by analysis of epidermal thickness, keratinocyte proliferation, subcutaneous adipose hypoplasia, and dermal changes after chronic treatment with FA and CpdA. RESULTS: In mouse keratinocytes in vitro and in vivo, CpdA did not activate GR-dependent genes but mimicked closely the inhibitory effect of glucocorticoid FA on the expression of inflammatory cytokines and matrix metalloproteinases. When applied topically, CpdA inhibited TPA-induced skin inflammation and hyperplasia. Unlike glucocorticoids, CpdA itself did not induce skin atrophy which correlated with lack of induction of atrophogene regulated in development and DNA damage response 1 (REDD1) causatively involved in skin and muscle steroid-induced atrophy. CONCLUSIONS: Overall, our results suggest that CpdA and its derivatives represent novel promising class of anti-inflammatory compounds with reduced topical side effects.

PURPOSE: Metastatic cancers spread from the primary site of origin to other parts of the body. Matrix metalloproteinase-9 (MMP-9) is essential in metastatic cancers owing to its major role in cancer cell invasion. Crotonis fructus (CF), the mature fruits of Croton tiglium L., have been used for the treatment of gastrointestinal disturbance in Asia. In this study, the effect of the ethanol extract of CF (CFE) on MMP-9 activity and the invasion of 12-O-tetradecanoylphorbol-13-acetate (TPA)-treated MCF-7 cells was examined. METHODS: The cell viability was evaluated using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. The expression of MMP-9 was examined by Western blotting, zymography, and real-time polymerase chain reaction. An electrophoretic mobility gel shift assay was performed to detect activator protein-1 (AP-1) DNA binding activity and cell invasiveness was measured by an in vitro Matrigel invasion assay. RESULTS: CFE significantly suppressed MMP-9 expression and activation in a dose-dependent manner. Furthermore, CFE attenuated the TPA-induced activation of AP-1. CONCLUSION: The results indicated that the inhibitory effects of CFE against TPA-induced MMP-9 expression and MCF-7 cell invasion were dependent on the protein kinase C δ/p38/c-Jun N-terminal kinase/AP-1 pathway. Therefore, CFE could restrict breast cancer invasiveness owing to its ability to inhibit MMP-9 activity.
