RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: This paper illustrates the results of an ethnobotanical study carried out in the Vesuvio National Park (VNP) (Campania, Southern Italy). It describes the medicinal uses of the plants in an ancient area rich in ethnobiodiversity investigated for the first time. AIM FOR THE STUDY: The main aim of the study was to understand at what extent current knowledge on medicinal plant uses is still alive in VNP. MATERIALS AND METHODS: The informations were collected using semi-structured and unstructured interviews performed on 136 persons living in the investigated area from March to November 2014 and from April to October 2015. The age of the informants ranged from 47 to 85 years old; more than half of the informants aged between 61 and 70. Local plant uses were listed and analyzed in a table and compared with uses in other localities in Italy and in other regions of the Mediterranean basin. RESULTS: In VNP were recorded a total number of 132 plant species, belonging to 110 genera and 51 families mentioned for medicinal purposes. Among the recorded 132 plant species, 70 are spontaneous or subspontaneous and 62 are cultivated above all in the kitchen gardens or in the apartments, as food or as ornamental. Herbs represent the majority, followed by trees and shrubs or subshrubs. The investigated plants were used to cure 116 different human health diseases and 4 veterinary problems. The majority of plants are used in the treatment of gastrointestinal, skin and respiratory problems. CONCLUSION: The number of medicinal plants reported in this paper reflects a well-preserved traditional popular knowledge (TPK) of the elderly people living in the rural areas and in the small villages of VNP. The conservation of TPK is owed to the persistence of an oral tradition that safeguard the use of plants as herbal medicine. We realized that while the use of some wild plants is decreasing, people continue to gather some cultivated and invasive plants for preparing remedies. Researches like this are necessary to protect ancient memories, to promote the transfer of information to the younger generations, to preserve ethno-biodiversity and to provide a starting point fur further biochemical investigations on medicinal entities.

Stenotrophomonas maltophilia is increasingly identified as an opportunistic pathogen in immunocompromised, cancer and cystic fibrosis (CF) patients. Knowledge on innate immune responses to S. maltophilia and its potential modulation is poor. The present work investigated the ability of 12 clinical S. maltophilia strains (five from CF patients, seven from non-CF patients) and one environmental strain to survive inside human monocyte-derived dendritic cells (DCs). The effects of the bacteria on maturation of and cytokine secretion by DCs were also measured. S. maltophilia strains presented a high degree of heterogeneity in internalization and intracellular replication efficiencies as well as in the ability of S. maltophilia to interfere with normal DCs maturation. By contrast, all S. maltophilia strains were able to activate DCs, as measured by increase in the expression of surface maturation markers and proinflammatory cytokines secretion.
RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: This study documents the pharmaceutical importance of plant resources in the South-Eastern area of the Partenio Regional Park (PRP), inland Campania, Avellino province. This is reflected in the great diversity of plants used for medicinal purposes as well as in their wide range of medicinal applications. MATERIALS AND METHODS: In order to collect information on medicinal plants used in the investigated area and to maximize the collection of local knowledge, informants were randomly contacted in the streets, squares and fields. Data were collected through both open and semi-structured interviews with native people between April 2012 and April 2013. RESULTS: The study recorded 87 plant species belonging to 76 genera and 35 families used as medicine for treating various diseases, both human and veterinary. Herbs represent the majority (56 species), followed by trees (18) and shrubs (13). Among the recorded plants, leaves were the most frequently used and topic use is the most common remedy. Cough is the most treated human disease followed by wounds healing. CONCLUSION: The investigated area is endowed with a strong tradition of herbal medicine usage for primary healthcare (PHC). The preservation of this knowledge is due to the continued use of plants for PHC by the local community. This is due to the fact that in the study area still exists an oral tradition that allows the persistence of such information. Recovering ancient knowledge is very important for preserving ethno-biodiversity and to discover new entities for a further evaluation of their biological activity.
