FORMULASI DAN UJI EFEKTIVITAS KRIM ANTIBAKTERI EKSTRAK ETANOL DAUN BELUNTAS (Pluchea indica Less.) TERHADAP BAKTERI Propionibacterium acnes

ABSTRACT Beluntas plants contain flavonoid compounds, which are know to have antibacterial activity. This study aims to make a formulate and test the physical stability of antibacterial cream prepared from Beluntas Leaf extract (Pluchea indica Less.) with three variations in extract concentrations of 5%, 10% and 15%, and  test the effectiveness of antibacterial against Propionibacterium acnes bacteria. The method of this research is experimental laboratory research. Beluntas leaves extract (Pluchea indica Less.) was obtained by maceration using 96% of ethanol and formulated into cream preparations with various extract concentrations. The result showed that Beluntas Leaf extract cream fulfilled the requirements of the physical properties of cream preparations, which included organoleptic test, homogeneity, pH, dispersion, adhesion, emulsion type and cycling test. On the result of antibacterial activity testing, the average diameter of the clear zone of prepared cream of Beluntas leaf extract was at concentration of 5%, 10% and 15%, respectively ie 6.16 mm, 7.83 mm, 10.16 mm. Based on the classification of antibacterial category, the inhibiting ability of the test bacteria by 5% and 10% cream was categorized as moderate, and 15% was categorized as strongly which is the most effective cream inhibiting the activity of Propionibacterium acnes. Keywords: Beluntas leaves, antibacterial cream, Propionibacterium acnes ABSTRAK            Tanaman Beluntas  merupakan salah satu tanaman  yang berkhasiat obat.

Protective roles of onion and garlic extracts on cadmium-induced changes in sperm characteristics and testicular oxidative damage in rats

Cadmium (Cd) is known to exert gonadotoxic and spermiotoxic effects. The present study was performed to assess the possible protective roles of onion (Allium cepa Linn) and garlic (Allium sativum Linn) extracts on Cd-induced testicular damage and spermiotoxicity. The control group received double distilled water; Cd group received Cd (1.5 mg/100 g BW/day) orally; extract-treated groups were pre-treated with varied doses of onion and/or garlic extract (0.5 ml and 1.0 ml/100 g BW/day) orally for one week and then simultaneously challenged with Cd (1.5 mg/100 g BW/day) for additional three weeks. Testicular tissue oxidant/antioxidant status and sperm characteristics were determined. Cd caused a marked (p < 0.001) rise in testicular lipid peroxidation (LPO) and glutathione S-transferase (GST) levels whereas glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) and alkaline phosphatase (ALP) levels were decreased. Cd intoxication significantly (p < 0.001) decreased epididymal sperm concentration and sperm progress motility, increased percent total sperm abnormalities and live/dead count. Both extracts successfully attenuated these adverse effects of Cd. Onion extract offers a dose-dependent protection. Our study demonstrated that aqueous extracts of onion and garlic could proffer a measure of protection against Cd-induced testicular oxidative damage and spermiotoxicity by possibly reducing lipid peroxidation and increasing the antioxidant defence mechanism in rats.

Quality of life measurement in alopecia areata. Position statement of the European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes

New treatment options may lead to an increased interest in using reliable and sensitive instruments to assess health-related quality of life in people with alopecia areata (AA). The purpose of this paper is to present current knowledge about quality of life assessment in AA. The dermatology-specific Dermatology Life Quality Index (DLQI) was the most widely reported health-related quality of life instrument used in AA. Three AA-specific (Alopecia Areata Symptom Impact Scale, Alopecia Areata Quality of Life Index and Alopecia Areata Patients'' Quality of Life) and three hair disease-specific instruments (Hairdex, Scalpdex and ‘hair-specific Skindex-29’) were identified with a range of content and validation characteristics: there is little evidence yet of the actual use of these measures in AA. Scalpdex is the best-validated hair disease-specific instrument. Further extensive validation is needed for all of the AA-specific instruments. The European Academy of Dermatology and Venereology Task Force on Quality of Life and Patient Oriented Outcomes recommends the use of the dermatology-specific DLQI questionnaire, hair disease-specific Scalpdex and the alopecia areata-specific instruments the Alopecia Areata Symptom Impact Scale or Alopecia Areata Quality of Life Index, despite the limited experience of their use. We hope that new treatment methods will be able to improve both clinical signs and health-related quality of life in patients with AA. In order to assess the outcomes of trials on these new treatment methods, it would be helpful when further development and validation of AA-specific instruments is being encouraged and also conducted. © 2021 European Academy of Dermatology and Venereology

Phase Coordinate System and p-q Theory Based Methods in Active Filtering Implementation

This paper is oriented towards implementation of the main theories of powers in the compensating current generation stage of a three-phase three-wire shunt active power system. The system control is achieved through a dSPACE 1103 platform which is programmed under the Matlab/Simulink environment. Four calculation blocks included in a specifically designed Simulink library are successively implemented in the experimental setup. The first two approaches, namely those based on the Fryze-Buchholz-Depenbrock theory and the generalized instantaneous reactive power theory, make use of phase quantities without any transformation of the coordinate system and provide the basis for calculating the compensating current when total compensation is desired. The others are based on the p-q theory concepts and require the direct and reverse transformation to/from the two-phases stationary reference frame. They are used for total compensation and partial compensation of the current harmonic distortion. The experimental results, in terms of active filtering performances, validate the control strategies implementation and provide arguments in choosing the most appropriate method

Methods to improve quality of life, beyond medicines. position statement of the European Academy of Dermatology and Venereology task force on quality of life and patient oriented outcomes

The pharmaceutical approach to skin disease has been hugely successful, but despite effective drugs being available and used, there are still vast numbers of people who continue to have some level of persisting skin disease and continue to experience quality of life (QoL) impairment. So the question that needs to be answered, while we await further advances in our drug‐based armamentarium, is how can we improve patients’ QoL, beyond drugs? A working group was formed from members of the EADV Task Force on QoL and Patient Oriented Outcomes. Participants were asked to suggest all the ways in which they considered patients’ QoL may be improved beyond medicines. Four groups of management approaches that may improve QoL in dermatology were identified: interventions within the dermatology service (hospitalization, multidisciplinary teams, patch testing and establishing relevant allergens and education), external services (corrective make‐up, climatotherapy and balneotherapy), psychological (psychological intervention, cognitive therapy, hypnosis), lifestyle (lifestyle behavioural changes, religion and spirituality and music). The ultimate aim of therapy is to eradicate a disease in an individual and return the person’s life to normal. But until the day comes when this has been achieved for every skin disease and for every patient there will be a need to support and assist many patients in additional non‐pharmaceutical ways. These ‘adjuvant’ approaches receive too little attention while dermatologists and researchers strive for better pharmacological therapy. The different ways in which patients may benefit have been reviewed in our paper, but the reality is that most have a very poor evidence base. The research challenges that we have to meet are to identify those approaches that might be of value and to provide evidence for their optimal use. In the meantime, clinicians should consider the use of these approaches where QoL remains impaired despite optimal use of standard therapy
