Anxiety disorders are highly prevalent, chronic, and disabling conditions that impose enormous health and economic costs both on individuals and on society. Medicinal plants are an invaluable source of bioactive metabolites that can be useful as new pharmacological treatment. Teas from Mentha spicata and Plantago major are employed by Colombian populations to treat stress and insomnia. This work was conducted to evaluate their anxiolytic and hypnotic properties. For this, we employed the Elevated Plus-Maze test and the sodium pentobarbital-induced hypnosis method using Wistar rats. Oral administration of M. spicata extract (1000 mg/Kg) significantly increased the exploration and time spent in the open arms, which indicates its anxiolytic activity. On the other hand, both M. spicata and P. major extracts (1000 mg/Kg) remarkably augmented the sleeping time induced by pentobarbital, suggesting a sedative and hypnotic effect of the plants extracts. In addition, the acute toxicological study demonstrated that the doses used did not induce mortality or toxicity effects at hepatic or renal level. The bioactivity seems to be related to several kinds of constituents, mainly phenolic compounds such as flavonoids and tannins. In conclusion, these results reinforce the potential use of these species in the therapy of anxiety.
We report on a case of cavernous hemangioma of the small bowel mesentery. Fewer than five cases of large mesenteric cavernous hemangioma have been reported in the English literature. Cavernous hemangioma of the small bowel mesentery is extremely rare. A 32-year-old black male presented with 1 week of abdominal pain, nausea, vomiting, and anorexia. He had recently undergone computed tomographic guided biopsy of a pelvic mass at another facility. Repeat CT guided biopsy was nondiagnostic, mesenteric angiography was inconclusive, and magnetic resonance imaging was performed as well. Complete workup was performed to localize primary source of abdominal mass and eventual open biopsy was planned resulting in en bloc resection of the mass, which had invaded the terminal ileum and appendix. Final pathologic diagnosis was cavernous mesenteric hemangioma. The patient experienced a prolonged postoperative ileus and was eventually discharged in stable condition, tolerating a regular diet with adequate bowel and urinary function. Diagnosis of cavernous mesenteric hemangioma is difficult and multiple imaging modalities can prove inconclusive. Adequate biopsy can be difficult to obtain even in patients with small body habitus. Standard of care is resection of entire mass en bloc.
The use of natural products by communities from the Colombian Caribbean region to treat health issues, together with biodiversity and geographical features, constitute a great scenery to develop new therapies based on ethnopharmacological heritage. Here, we investigated the anti-inflammatory potential of 10 commonly used plants in Colombian folk medicine, evaluating their effect on nitric oxide (NO) production by LPS-stimulated RAW 264.7 macrophages. The most active plant was evaluated in vivo using 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced mouse ear edema, along with its effect on the production of pro-inflammatory mediators in vitro. The extract of Physalis angulata L. calyces showed the highest activity. This extract was fractionated and its dichloromethane fraction (DF) was the most active in vitro, inhibiting the production of NO, prostaglandin E2 (PGE2), interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α and monocyte chemotactic protein (MCP)-1 (CCL2). In vivo, DF showed a significant inhibition of ear edema and myeloperoxidase (MPO) activity, with evident reduction of the leukocyte infiltration into tissue. Our results support the ethnopharmacological use of the selected plants in folk medicine. P. angulata dichloromethane fraction represents a promising source of pharmacological compounds with great potential therapeutic use to treat inflammatory illness.
The gastrointestinal tract is the most common extranodal site of primary non-Hodgkin's lymphoma. We present a case of a 50-year-old male with primary B cell lymphoma arising in an S-pouch eight years after a total proctocolectomy for ulcerative colitis. After chemoradiotherapy the patient remained asymptomatic, with an intact S-pouch. Pouch conservation is feasible in patients with primary lymphoma of the pouch, using chemoradiotherapy and close follow-up examinations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
