Nanotechnology-based drug delivery systems and herbal medicines: a review

Herbal medicines have been widely used around the world since ancient times. The advancement of phytochemical and phytopharmacological sciences has enabled elucidation of the composition and biological activities of several medicinal plant products. The effectiveness of many species of medicinal plants depends on the supply of active compounds. Most of the biologically active constituents of extracts, such as flavonoids, tannins, and terpenoids, are highly soluble in water, but have low absorption, because they are unable to cross the lipid membranes of the cells, have excessively high molecular size, or are poorly absorbed, resulting in loss of bioavailability and efficacy. Some extracts are not used clinically because of these obstacles. It has been widely proposed to combine herbal medicine with nanotechnology, because nano-structured systems might be able to potentiate the action of plant extracts, reducing the required dose and side effects, and improving activity. Nanosystems can deliver the active constituent at a sufficient concentration during the entire treatment period, directing it to the desired site of action. Conventional treatments do not meet these requirements. The purpose of this study is to review nanotechnology- based drug delivery systems and herbal medicines.

Avaliação dos efeitos promovidos pela sibutramina, associadas ou não à nicotina, nos tecidos reprodutivos de ratas albinas

Sibutramine is a drug recommended clinically for the treatment of obesity, but there are women that use the drug for maintenance of body weight. Many time this use occur associate to habit of tabagism, being the nicotine the main toxic compound in the cigarette. The goal of study was to evaluate the side effects promoted by sibutramine, associated or not to nicotine, in the reproductive tissue of adult female rats. Wistar animals (n = 30), were distributed in the groups: a) Control A (0.3 mL of distilled water; oral); b) Sibutramine (15 mg/kg of body weight; oral); c) Control B (0.3 mL of saline solution; intraperitoneal); d) Nicotine (4.0 mg/kg of body weight; intraperitoneal); e) sibutramine + nicotine. The treatments were conducted during 30 consecutive days (single dose, daily). Sibutramine, associated or not to nicotine, affected the folliculogenesis and luteogenesis. There were significant alterations (p<0.05) in the thickness of uterine layers, considerate each treatment. In conclusion, the administration isolated of sibutramine or nicotine promoted deleterious effects in the reproductive tissues of female rats and these effects were potential in the group that received both drugs.

Immunomodulatory effects of low dose chemotherapy and perspectives of combanation with immunotherapy

Nowadays cancer is one of the main causes of death and many efforts worldwide have been driven to find out new treatments and approaches in order to extinguish or reduce this group of disorder. Chemotherapy is the main treatment for cancer, however, conventional schedule based on maximum tolerated dose (MTD) show several side effects and frequently allow the development of drug resistance. In this review we present the evidence that metronomic chemotherapy, based on the frequent administration of low or intermediate doses of chemotherapeutics is as efficient as MTD and works better in some situations. Finally, we present some data indicating that noncytotoxic concentrations of antineoplastic agents are able to both up-regulate the immune system and increase the susceptibility of tumor cells to cytotoxic T lymphocytes. Taken together, data from the literature provide us the evidence that low concentrations of selected chemotherapeutics agents, rather than conventional high doses, should be chosen for combination with immunotherapy
