One of the most common drugs used against a wide variety of anaerobic protozoan parasites is metronidazole. However, this drug is mutagenic for bacteria and is a potent carcinogen for rodents. Thymus vulgaris is used for cough suppression and relief of dyspepsia. Also it has antibacterial and antifungal properties. The aim of this study was to investigate antiamebic effect of Thymus vulgaris against Entamoeba histolytica in comparison with metronidazole. One hundred gram air-dried T. vulgaris plant was obtained and macerated at $25^{\circ}C$ for 14 days using n-hexane and a mixture of ethanol and water. For essential oil isolation T. vulgaris was subjected to hydrodistillation using a clevenger-type apparatus for 3 hr. E. histolytica, HM-1: IMSS strain was used in all experiments. It was found that the minimal inhibitory concentration (MIC) for T. vulgaris hydroalcoholic, hexanic extracts, and the essential oil after 24 hr was 4 mg/mL, 4 mg/mL, and 0.7 mg/mL, respectively. After 48 hr the MIC for T. vulgaris hydroalcoholic and hexanic extracts was 3 and 3 mg/mL, respectively. Therefore, it can be concluded that the Iranian T. vulgaris is effective against the trophozoites of E. histolytica.

Ability of water extract from Prunella vulgaris Labiatae to stimulate immune system and inhibit tumor metastasis in mice was assessed. In experimental lung metastasis, prophylactic intravenous (i.v.) administration of water extract from P. vulgaris significantly inhibited lung metastasis in a dose-dependant manner. Peritoneal macrophages stimulated with P. vulgaris produced various cytokines such as tumor necrosis factor (TNF)-$\alpha$ and interlukin (IL)-12 as well as induced tumoricidal activity. In an assay for natural killer (NK) cell activity, i.v. administration of P. vulgaris significantly augmented NK cytotoxicity. The depletion of NK cells by injection of rabbit anti-asialo GM1 serum abolished the inhibitory effect of P. vulgaris on lung metastasis of colon26-M3.1 cells. These data demonstrate that P. vulgaris activate innate immune system to inhibit the growth of foreign materials including tumor cells in mice.

Acne vulgaris is a common inflammatory skin disease of the pilose-baceous unit. It appears as lesions consisting of comedones, papules, pustules, and nodules of varying shapes and severity. In general, the first-line treatment for acne vulgaris includes topical and oral medication. Recently, various physical modalities have also been investigated. The use of laser therapy is steadily increasing because of its fewer side effects, short procedure time, and rapid results. In particular, laser therapy assisted with carbon suspension application is effective for acne vulgaris but may sometimes result in discomfort due to odor and dust formation during the procedure. Herein, we report that acne vulgaris and enlarged facial pores can be safely and effectively treated with laser therapy assisted with diamond particle suspension and gold microparticle application, which can address the discomfort caused by the carbon suspension application.

Tests of stability and toxicity, and clinical evaluation of anti-acne activity suggest that cryptotanshinone, a constituent of the roots of Salvia miltiorrhiza Bunge, is an effective active ingredient for acne vulgaris treatments. Acne vulgaris, called acne or pimples, is the most common disease of the pilosebaceous follicle unit of the skin. It affects nearly 80% of people between the ages of 11 and 30. Approximately 30% of teenagers have acne of sufficient severity to require medical treatment. Acne is a follicular disorder of the skin. It occurs in specialized pilosebaceous units on the face and body. Acne develops when these specialized follicles undergo pathologic alterations that result in the formation of non-inflammatory lesions (comedones) and inflammatory lesions (papules, pustules and nodules). An abnormality of keratinizing epithelium of these follicles, thought to be due to the action of sebum synthesized and secreted by the androgen-sensitive sebaceous glands, leads to inflammation induced by the follicular bacterium Propionibacterium acnes. Therapy involves treatments that modify these pathogenic factors and includes drugs with antikeratinizing, antibacterial and antiseborrheic actions. Acne vulgaris is a very frequent disease, seen primarily in adolescents, involving the sebaceous follicles. Acne vulgaris is characterized by a great variety of clinical inflammatory and non-inflammatory lesions: comedones, papules, pustules, nodules, cysts and scars. Acne vulgaris is a multi-factorial disease. Although its pathogenicity is unclear, extensive studies have shown that hyperseborrhea, superinfection by P. acnes and endocrinologic androgenic changes play a role in the development of acne vulgaris.

Bioremediation has been recognized as a suitable alternative to conventional methods of removing contaminants, and it uses fungi, bacteria and microalgae. In contrast to other organisms, microalgae are unique in that they have the ability to perform photosynthesis like plants and to utilize organic/inorganic carbon substrates, in a process called phytoremediation. Microalgae can populate a reaction site rapidly and enhance the bioremediation efficiency. In this study, Chlorella vulgaris was used to evaluate the removal potentials of the nutrients (N and P) and heavy metals (Cu and Zn) from swine wastewater. The optimum growth conditions for Chlorella vulgaris and the removal potentials of N, P, Cu, and Zn from synthetic wastewater using Chlorella vulgaris were investigated. Based on the results, the applicability of this microalga to on-site wastewater treatment was examined. Optimal growth conditions for Chlorella vulgaris were established to be $28^{\circ}C$, a pH of 7, and light and dark cycles of 14:10 h. As the concentrations of the nutrients were increased, the efficiencies of N and P removal efficiencies by Chlorella vulgaris were decreased in the single and binary mixed treatments of the nutrients, respectively. Further, the efficiencies of Cu and Zn removal also decreased as the heavy metals concentrations added were increased, both in the single and binary mixed treatments. In addition, the efficiency of Cu removal was higher than that of Zn removal. Our results indicate that Chlorella vulgaris could be used in treatment plants for the removal of nutrients and heavy metals from swine wastewater.

Chlorella vulgaris, a genus of single-cell green algae, is considered to be a very essential resource for the higher value-added business including functional food and biodiesel, due to its high contents of protein, carbohydrate and lipid. In this study, ultraviolet rays were irradiated in order to induce the mutation of C. vulgaris. After inducing the mutation, UV1-20 mutant, high in lipid was selected and its cell growth rate, dry weight, pigment content and lipid content were measured. The growth rate of the UV1-20 mutant was increased almost 1.5 times than the wild type, but pigment contents of chlorophyll and carotinoid were decreased. In addition, the lipid content of UV1-20 was increased 1.8 times than the wild type. Therefore, C. vulgaris mutant, isolated in this study, is considered to have sufficient potential to be used as a material for the higher value-added business.

Acne vulgaris is a common dermatological condition affecting the pilosebaceous units and having a multifactorial etiology. In Unani terminology, acne vulgaris is referred as Busoor Labaniya, characterized by white lesions on the face, nose, and cheeks; on squeezing, release cheesy material. In conventional medicine, mild cases are best addressed with topical regimens, but more severe cases require systemic medications. Retinoids (retinoic acid, adapalene, isotretinoin, tazarotene), benzoyl peroxide, clindamycin, erythromycin, and azelaic acid are a few examples of topical medications, whereas systemic drugs include antibiotics (Doxycycline, minocycline, erythromycin, azithromycin). In the Unani System of Medicine, numerous single and compound drugs have been used to treat Busoor Labaniya. These drugs are considered harmless and do not have any major side effects. In Unani system of medicine, acne vulgaris is effectively managed with natural medicines as well as therapeutic regimens with minimal side effects even after long-term usage. Acne vulgaris is usually treated with systemic blood purifiers along with topical Unani drugs. Hence, clinical studies with proper scientific parameters are needed to be conducted to establish and validate their efficacy in the prevention and control of acne vulgaris.

The aim of this study is to optimize the efficiency of a photobiorector on the growth rate of Chlorella vulgaris (C. vulgaris) by varying distance of optical panel (OP). The round shaped C. vulgaris (FC-16) having the size of $3-8{\mu}m$ is employed in this study. The cells of C. vulgaris are cultured in the Jaworski's Medium with deionized water at $22^{\circ}C$ for 15 days. The OP is placed at four different distances i.e., at 225 mm distance (Run 1), 150 mm distance (Run 2), 112.5 mm distance (Run 3) and 90 mm distance (Run 4) having a LED (Light Emitting Diode) source. The diffuse rate is achieved to 86%, 90%, 92% and 94% for Run 1, Run 2 Run 3 and Run 4, respectively. A narrower distance of OP caused to effectively to increase the efficiency of diffuse light rate. For mass cultivation of this biomass, medium is changed according to distance of OP after attaining a maximum biomass concentration; Run 1 in 8 days, Run 2 in 6 days, Run 3 in 4 days and Run 4 in 3 days. In addition, the amount of maximum biomass rate for Run 4 was reached 3 times higher than that of Run1. However, growth rate, chlorophyll per cell, cell volume and doubling time are found to be Run 3 and Run 4 higher than that of Run 1 and Run 2 samples. However, Run 3 and Run 4 are having a slight difference in all these measurements. These findings suggest that in terms of economic consideration and efficiency towards simultaneous mass cultivation of biomass, Run 3 was found to be more effective than other samples.

Rare earth contents(REE) were analysed for the plants, M. sinensis. A. vulgaris and R. crataegitolius, from two different soils serpentine area consisting of serpentinite(SP) and non-serpentine area, containing amphibole schist(AS) of Gapyeong area, and were compared with soils and host rocks. The AS were high with the differences of several times in the top soils, and with the differences of several to ten times in the host rocks relative to the SP. In the same area, the SP were high in the soil, but the rocks for the AS. In the plants, the A. vulgaris were high, but low in the R. crataegitolius. Root parts were higher than the upper parts. Differences between the upper and root parts were big in the SP rather than the AS, and were big in the R. crataegitolius, but small in the M. sinensis. Among the parts of the plants, high elements were shown in the R. crataegitolius of the SP, and the A. vulgaris and M. sinensis of the AS. In the correlation coefficients, most of the REE showed positive relationships among the element pairs, especially high positive correlation coefficients in the upper parts of the SP.Differences of the soils and plants(average) were smalle in the M. sinensis and big in the R. crataegitolius. In the upper parts. contents of the A. vulgaris were close to the soils while the R. crataegitolius showed large discrepancies with the soils. In the root parts, contents of the A. vulgaris showed discrepancies with the soils regardless of soil types, but close in the R. crataegitolius of the SP and M. sinensis of the AS.
