Article Synopsis
- The study aimed to investigate the interactions between ethanol extracts of two plants, Amburana cearensis and Anadenanthera macrocarpa, and six antimicrobial drugs against resistant strains of Staphylococcus aureus and Escherichia coli.
- The antibacterial effectiveness was measured using the minimum inhibitory concentration (MIC) method, and a microdilution assay was conducted to explore interactions between the natural extracts and antibiotics.
- Notably, the combination of amikacin with Anadenanthera macrocarpa extract significantly improved its effectiveness against one E. coli strain, while β-lactam antibiotics generally did not show enhanced activity, and some interactions, like with ampicillin, were antagonistic.
Purpose: Study the proliferation rate of jejunum and large intestine crypt epithelial cells, in rats pinealectomized immediately after birth.
Methods: Twenty-four male Wistar rats were distributed into two groups: Acute group (n=12) and Chronic group (n=12). Six animals of each group were operated for removal of the pineal gland (pinealectomy-PnX), and other six were controls (sham pinealectomy-C).
Hyperplasia of the colonic neuroendocrine cells after pinealectomy in rats. The new evidence for the existence of connections between the distant parts of the diffuse neuroendocrine system.
Neuro Endocrinol Lett
October 2005
Objectives: The diffuse neuroendocrine system (DNES) participates in the systemic homeostasis and may work as a unified system with integrated functions but anatomically disperse. However, the mechanisms that are involved in the integration of the distant parts of the DNES are poorly known. This study is aimed on the effects of a pinealectomy on the population of the neuroendocrine cells (NECs) in the colon of rats.
