In vivo topical anti-inflammatory and in vitro antioxidant activities of two extracts of Thymus satureioides leaves.

Four extracts at increasing polarity were prepared from the leaves of Thymus satureioides Coss. (Labiatae) and assayed for the in vivo topical anti-inflammatory effect using the croton oil ear test in mice, and for in vitro both antioxidant (DPPH degrees test) and anti-bacterial (broth microdilution method) activities. The chloroform extract showed a topical anti-inflammatory activity (ID50=282 microg cm(-2)), only three times lower than that of the reference drug indomethacin (ID50=93 microg cm(-2)) and its active components were identified as ursolic and oleanolic acids. The methanol extract, showing a significant radical-scavenging effect (SC50=14.54 microg), was characterized by the isolation and identification of some flavonoids. On the contrary, the extracts did not show any anti-bacterial effect against four standard aerobial bacteria strains.

Screening of anti-bacterial activity of medicinal plants from Belize (Central America).

Twenty-one extracts from seven herbal drugs, Aristolochia trilobata (Aristolochiaceae) leaves and bark, Bursera simaruba (Burseraceae) bark, Guazuma ulmifolia (Sterculiaceae) bark, Hamelia patens (Rubiaceae) leaves and Syngonium podophyllum (Araceae) leaves and bark, used in traditional medicine of Belize (Central America) as deep and superficial wound healers, were evaluated for their anti-bacterial properties. Activity was tested against standard strains of Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 25923 and Enterococcus faecalis ATCC 29212. Almost all the extracts were able to inhibit the growth of one or more of the bacterial strains, except that of Enterococcus faecalis. For the first time an anti-microbial activity is reported for Aristolochia trilobata as well as for Syngonium podophyllum. The hexane extracts of Aristolochia trilobata leaves and bark were the most active extracts against Staphylococcus aureus (MIC=0.31 and 0.625mg/ml, respectively).

["In vitro" sensitivity of bacterial strains isolated from urine cultures in the period 1995/96].

Urinary tract infections represent a very frequent pathology. An epidemiologic survey on 6632 urine samples has been performed in the years 1995/96 to verify the bacterial incidence and susceptibility to antimicrobial drugs in this period, and variations in the resistance patterns with respect to a previous study. The results suggest the importance of a constant epidemiological surveillance in the community setting.

[Epidemiologic surveillance of streptococcus pyogenes resistances to macrolides and lincosamides].

With the changing face of modern medicine and increased use of new antimicrobial compounds against Streptococcus pyogenes, as macrolides, in recent years more strains developed new resistance to macrolides and lincosamides. This is of interest because some scientists believe that the new antibiotics policies possibly influence the rate of resistance in Streptococcus pyogenes: the pattern of resistance to macrolides is complex and involving cross or co-resistance with chemically unrelated or related agents, as lincosamides. To obtain current epidemiological data on antimicrobial resistance of Streptococcus pyogenes, we performed an year surveillance study: the rate of resistance to erythromycin was from 4% in October 1994 to 55% in December 1995, and in the same time clarithromycin was from 0% to 46% and clindamycin from 0% to 32%.
