MICs were determined for 15 antimicrobial agents against 37 Mycoplasma putrefaciens isolates. The most effective antimicrobial drug classes were the fluoroquinolones, the tetracyclines, the lincosamide lincomycin, and the macrolides. The susceptibility profile of the isolates correlated with the geographic origin. This is the first report of decreased susceptibility to the macrolides, lincomycin, and the tetracyclines in M. putrefaciens strains. 相似文献

Linitis plastica of the rectum is an uncommon entity that is difficult to diagnose due to the lack of mucosal lesions on endoscopy, the low diagnostic yield of biopsy and non-specific findings of barium radiology and computerized tomography. Rectal endoscopic ultrasonography has had a radical impact on the differential diagnosis of stenosing lesions of the rectum, among them linitis plastica, allowing diagnosis of this lesion even in patients with negative results of biopsy. 相似文献

As part of our ongoing research into botanical therapies for anxiety disorders, the neotropical vine Souroubea sympetala was chosen for study as a phytochemical discovery strategy focusing on rare Central American plant families. When orally administered to male Sprague-Dawley rats, the crude plant extract, its ethyl acetate fraction, supercritical carbon dioxide fraction, or its isolated triterpenes reduced anxiety and/or fear-related behavior in standardized behavioral models. Pharmacological studies showed that the extracts acted at the benzodiazepine GABAA receptor and reduced corticosterone levels. A preparation containing Souroubea fortified with a second triterpene containing plant, Platanus occidentalis, was shown to be safe in a 28-day feeding trial with beagles at 5 times the intended dose. Subsequent trials with beagles in a thunderstorm model of noise aversion showed that the material reduced anxiety behaviors and cortisol levels in dogs. The formulation has been released for the companion animal market in Canada and the USA under the Trademark “Zentrol.” Ongoing research is exploring the use of the material in treatment of anxiety and post-traumatic stress in humans. 相似文献

The purpose of this scanning electron microscope study was to observe the interface between dentin and amalgam utilizing various adhesive resin cements. The adhesive resin materials used in this study were Imperva Dual, Geristore, and Panavia. The scanning electron micrographs revealed that bonds were established between amalgam, adhesive resins, and dentin. 相似文献

Antifungal Saponins from the Maya Medicinal Plant Cestrum schlechtendahlii G. Don (Solanaceae) 下载免费PDF全文
Elizabeth Roberts Rui Liu Christopher D. Mogg Ammar Saleem Marco Otárola‐Rojas Luis Poveda Pablo Sanchez‐Vindas Victor Cal Federico Caal Rajagopal Subramaniam Myron L. Smith John T. Arnason 《Phytotherapy research : PTR》2016,30(3):439-446
Bioassay‐guided fractionation of the crude extract (80% EtOH) of the leaves of Cestrum schlechtendahlii, a plant used by Q'eqchi' Maya healers for treatment of athlete's foot, resulted in the isolation and identification of two spirostanol saponins (1 and 2). Structure elucidation by MS, 1D‐NMR, and 2D‐NMR spectroscopic methods identified them to be the known saponin (25R)‐1β,2α‐dihydroxy‐5α‐spirostan‐3‐β‐yl‐O‐α‐l ‐rhamnopyranosyl‐(1 → 2)‐β‐d ‐galactopyranoside (1) and new saponin (25R)‐1β,2α‐dihydroxy‐5α‐spirostan‐3‐β‐yl‐O‐β‐d ‐galactopyranoside (2). While 2 showed little or no antifungal activity at the highest concentration tested, 1 inhibited growth of Saccharomyces cerevisiae (minimum inhibitory concentration (MIC) of 15–25 μM), Candida albicans, Cryptococcus neoformans, and Fusarium graminearum (MIC of 132–198 μM).
