Chemical constituents of the essential oil in above-ground and root of Bupleurum malconense and root of B. chinense were investigated by GC-MS compiled with automated mass spectral deconvolution and identification system (AMDIS) and retention index. The results showd that the components of essential oil in B. malconense have some similarities with the one in B. chinense, and both of them have the higher content of caryophyllene oxide which is an active component of anti-inflammatory and analgesic. These results suggested that as a local substitute, B. malconense has a certain scientific basis of the treatment for cold fever.

Danshen, the dried root or rhizome of Salvia miltiorrhiza Bge., is a traditional and folk medicine in Asian countries, especially in China and Japan. In this review, we summarized the recent researches of Danshen in traditional uses and preparations, chemical constituents, pharmacological activities and side effects. A total of 201 compounds from Danshen have been reported, including lipophilic diterpenoids, water-soluble phenolic acids, and other constituents, which have showed various pharmacological activities, such as anti-inflammation, anti-oxidation, anti-tumor, anti-atherogenesis, and anti-diabetes. This article intends to provide novel insight information for further development of Danshen, which could be of great value to its improvement of utilization.

PURPOSE: The purpose of this study was to evaluate the effects of essential oil on oxidative stress, immunity, and skin condition in atopic dermatitis (AD) induced mice. METHODS: This study was a 3x3 factorial design. Factors were oil type (Lavender, Thyme, and 2:1 mixture of lavender and thyme oil [blending oil]) and treatment period (0 day, 7 days, and 21 days). The samples were 45 mice with AD and randomly assigned to nine groups of five mice per group. The dependent variables such as superoxide radical, IgE, degranulated mast cells, and epidermal thickness were measured. Data were collected from February to April in 2014. Descriptive statistics, One-way ANOVA, Two-way ANOVA, and Tukey's HSD test were performed using the SPSS WIN 20.0 program. RESULTS: Dependent variables were not statistically significantly different by the three oil types (p >.05). Essential oils such as lavender, thyme, and blending oil were all effective in reducing AD symptoms and especially 2:1 blending oil were most effective. There were statistically significant differences by the three treatment periods in all dependent variables (p <.001). There were statistically significant interactions between oil types and treatment periods in all dependent variables (p <.01). For decreasing superoxide radical, degranulated mast cells, and epidermal thickness, 2:1 mixed oil should be applied for at least 21 days. Otherwise to reduce IgE, 2:1 mixed oil should be used for at least 7 days. CONCLUSION: These findings provide bases for developing effective interventions for AD patients to manage their AD symptoms.

AIM: To evaluate the effect of Cocus nucifera L. flowers in reducing the major multiple symptoms of letrozole-induced polycystic ovarian disease (PCOD) in female rats. METHOD: Female, virgin Wistar rats were treated with letrozole (1 mg/kg body wt) to induce PCOD, and after 21 days of induction rats were administered orally with 100 and 200 mg·kg(-1) of Cocus nucifera flower aqueous extract, respectively. Estrus cycle and blood sugar were monitored once a week throughout the study. After scarification, various biochemical parameters, such as antioxidant status (superoxide dismutase (SOD) and glutathione reductase (GSH)) of the uterus homogenate, lipid profile (total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), and triglycerides (TG)) of the serum were determined. Weights of the uterus and ovaries were separately monitored. The characteristics of changes in the ovary were evaluated by histopathological studies. RESULTS: GC-MS analysis of the aqueous extract showed the presence of volatile and pharmacologically active phytoconstituents. C. nucifera flower extract-treated groups showed estrus cyclicity and increased uterus weight which indicates the estrogenic effect. The improved blood sugar level, ideal lipid profile, good antioxidant status, and histopathology results revealed the recovery from poly cystic ovaries. CONCLUSION The results indicate that C. nucifera flower is a potential medicine for the treatment of PCOD and this study supports the traditional uses of C. nucifera flower.

OBJECTIVEUlcerative colitis is a chronically recurrent inflammatory bowel disease of unknown origin. In the present study, the effect of ginger (rhizome of Zingiber officinale Roscoe) volatile oil on a rat model of colitis was evaluated.

METHODSVolatile oil of ginger with doses of 100, 200, and 400 mg/kg, prednisolone (4 mg/kg), or vehicle were administered orally to groups of male Wistar rats (n = 6) for 5 d. Animals were randomly divided into 6 groups, each group consisting of 6 rats. Colitis was induced by intracolonic instillation of 2 mL of 4% (v/v) acetic acid solution. All rats were sacrificed 24 h later and the tissue injuries were assessed macroscopically and histopathologically.

RESULTSGinger volatile oil with all doses reduced colon weight/length ratio (P < 0.01) and the effects were similar to the reference drugs. Higher oral doses of volatile oil (200 and 400 mg/kg) reduced ulcer severity (P < 0.05 and P < 0.01), ulcer area (P < 0.01) and ulcer index (P < 0.01). On the other hand, evaluation of microscopic scores showed that the dose of 400 mg/kg of volatile oil was effective to reduce inflammation severity (P < 0.01) and inflammation extent (P < 0.05) compared to the control group.

CONCLUSIONIt is concluded that ginger volatile oil could effectively reduce symptoms of experimental colitis in a dose-dependent manner.

AIM: To examine the possible protective effect of Satureja khuzistanica essential oil (SKE) on antioxidant enzyme activity in alloxan-induced Type 1 diabetic rats. METHOD: Thirty Sprague-Dawley male rats were divided into three groups randomly; group one as control, group two diabetic, with no treatment, and group three treatment with SKE at 500 ppm in drinking water, respectively. Diabetes was induced in the second and third groups by alloxan injection subcutaneously. After eight weeks, animals were anaesthetized. Blood samples were also collected before killing to measure antioxidant enzymes activity. RESULTS: SKE significantly increased the serum level of glutathione and the serum activity of glutathione peroxidase, superoxide dismutase, and catalase in the treated group compared with the diabetic untreated group. CONCLUSION The findings showed that SKE exerts beneficial effects on the antioxidant enzymes activity in alloxan-induced Type 1 diabetic rats.

OBJECTIVETo investigate the effect of spearmint oil on emphysema-like changes and the expression of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta(IL-1beta), matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-9) in lipopolysaccharide (LPS) treated rats.

METHODEmphysematous changes model was induced by intratracheal instillation of LPS once a week for up to 8 weeks in rats. Rats were divided into control, dexamethasone (0.3 mg x kg(-1)), and spearmint oil (10, 30,100 mg x kg(-1)) groups. Each group was treated with saline, dexamethasone, and spearmint of oil respectively for 4 weeks. Then total and different white blood cell counts in bronchoalveolar lavage fluid(BALF) were carried out. The pathologic changes of lung tissue such as alveolar structure, airway inflammation, and goblet cell metaplasia were observed by HE and AB-PAS staining. Expression of TNF-alpha, IL-1beta, TIMP-1 and MMP-9 were measured.

RESULTBoth spearmint and dexamethasone decreased the destruction of pulmonary alveolus. The total and different white blood cell counts in BALF including neutrophile and lymphocyte of spearmint oil 100 mg x kg(-1) and dexamethasone group were significantly reduced, and the goblet cell metaplasia was also inhibited. Dexamethasone had inhibitory effect on the expression of TNF-alpha, IL-1beta, TIMP-1 and MMP-9. Spearmint oil 30, 100 mg x kg(-1) significantly reduced TNF-alpha and IL-1beta respectively. Spearmint oil 10, 30 and 100 mg x kg(-1) had no effect on the expression of TIMP-1, but could decrease the expression of MMP-9 significantly in lung tissues.

CONCLUSIONSpearmint oil has protective effect on rats with emphysematous changes, since it improves alveolar destruction, pulmonary inflammation, and goblet cell metaplasia. The mechanism may include reducing TNF-alpha, IL-1beta content and inhibiting overexpression of matrix metalloproteinase-9 in lung tissues.
