Medicinal Plant Extracts and Their Use As Wound Closure Inducing Agents.

Skin insult and damage start a complex healing process that involves a myriad of coordinated reactions at both the cellular and molecular level occurring simultaneously. These processes can be divided into that of cell migration and tissue remodeling of the wound. In addition, it is well known that deep wounds that derive from surgical procedures need a multidisciplinary approach to have a successful wound healing process. Recently, there has been a renowned interest in the identification of active compounds derived from ornamental, edible, and wild plants being used in the cosmetic and skin product industry. Recent reports suggest that active components of several plants such as Propolis and Aloe vera could be used to induce the process of wound healing and tissue regeneration and reducing therefore the time to complete wound closure. Other plant species such as Achillea millefolium or Salvia officinalis have anti-inflammatory properties and promote cellular proliferation contributing to faster tissue regeneration. It has been described that Malva sylvestris influences the formation of fibrosis-free granulation tissue in the skin. Recent observations suggest that Casearia sylvestris induces the angiogenic process. These effects have been evaluated in cell lines, different animal models, and some in randomized clinical trials. In this review we summarize the evidence of plant extracts and their active components (when known) in the acceleration of the wound closure process and tissue repair.

Causas de hospitalización del adulto con diabetes mellitus tipo 2 / Causes of hospitalization in older adults diagnosed with type 2 diabetes mellitus

Introducción: El propósito del estudio fue determinar la prevalencia de causas de hospitalización del adulto con diabetes mellitus tipo 2. Metodología: El diseño fue de tipo epidemiológico, por encuesta de prevalencia. La muestra fue a través del censo de pacientes que ingresaron a un hospital de segundo nivel.

Gastrointestinal response to oral versus gastric feeding of defined formula diets.

The gastrointestinal response in rats nourished by continuous intragastric infusion of a variety of defined formula diets was compared with animals consuming the same diets orally. Two groups of rats were fed isocaloric amounts of DFD (73 kcal/day); group 1: sham-operated, orally-fed; group 2: operated, intragastrically-fed. Diets included; Vivonex (V), Flexical (F), Vital, Vivonex high nitrogen, and a control casein rat liquid formula diet (C). After 2 wk rats were killed and the liver, pancreas, and small bowel removed. The bowel was divided into eight equal segments. Mucosal weight, DNA, and protein concentration per cm segment were measured Pancreatic amylase activity (units/g), and liver weight and lipid content were measured. Weight gain was comparable in all oral-fed groups, but was decreased in all gastric-fed animals compared to the oral-fed group. Nitrogen retention was not influenced by route of feeding but was significantly lower for Vivonex and Flexical animals (p less than 0.01) in both oral-fed and gastric-fed groups. There was significant accumulation of lipid in the liver of both oral-fed and gastric-fed animals sustained on Vivonex and Vivonex high nitrogen (p less than 0.01). Most proximal intestinal segment weight and mucosal weight, protein and DNA were decreased compared to the control diet in both oral-fed and gastric-fed animals. These studies demonstrate that while the gastrointestinal response to isocaloric defined formula diets was significantly influenced by the specific diet, fewer responses were modified by feeding defined formula diets orally versus gastrically.

Gastrointestinal response to nutrient variation of defined formula diets.

The gastrointestinal response to oral alimentation of low residue commercial defined formula diets or a rat liquid formula was studied. Male Sprague-Dawley rats (220-250 g) were fed isocaloric amounts (73 kcal/day) of Vivonex (V), Vivonex HN (VHN), Flexical (F), Vital (Vit), or a control Casein diet 116EC (C). Nitrogen (N) retention was calculated from N intake minus N excretion/day. After 2 weeks, rats were killed and the liver, pancreas, and small bowel removed and weighed. Pancreatic amylase activity (U g) and liver lipid were measured. The bowel was divided into eight equal segments, and mucosal weight, DNA, and protein concentration per centimeter were measured. Despite isocaloric feeding, body weight gain was lower in V and VHN groups, and higher in F and Vit groups compared to the C. Amylase specific activity was increased in V, VHN, and F groups, while the liver lipid was increased in the V and VHN groups when compared to C animals. The most proximal intestinal segment weight, mucosal weight, protein and DNA of V, VHN, and Vit groups were less than C animals, while distal segments were similar. F animals showed greater intestinal mass than C rats. These studies indicate statistically significant differences in gastrointestinal response as a result of nutrient variation of defined formula diets.
