Potential Therapeutic Effects of Natural Plant Compounds in Kidney Disease.

BACKGROUND: The blockade of the progression or onset of pathological events is essential for the homeostasis of an organism. Some common pathological mechanisms involving a wide range of diseases are the uncontrolled inflammatory reactions that promote fibrosis, oxidative reactions, and other alterations. Natural plant compounds (NPCs) are bioactive elements obtained from natural sources that can regulate physiological processes. Inflammation is recognized as an important factor in the development and evolution of chronic renal damage. Consequently, any compound able to modulate inflammation or inflammation-related processes can be thought of as a renal protective agent and/or a potential treatment tool for controlling renal damage. The objective of this research was to review the beneficial effects of bioactive natural compounds on kidney damage to reveal their efficacy as demonstrated in clinical studies. METHODS: This systematic review is based on relevant studies focused on the impact of NPCs with therapeutic potential for kidney disease treatment in humans. RESULTS: Clinical studies have evaluated NPCs as a different way to treat or prevent renal damage and appear to show some benefits in improving OS, inflammation, and antioxidant capacity, therefore making them promising therapeutic tools to reduce or prevent the onset and progression of KD pathogenesis. CONCLUSIONS: This review shows the promising clinical properties of NPC in KD therapy. However, more robust clinical trials are needed to establish their safety and therapeutic effects in the area of renal damage.

FASE INTESTINAL DE Trichinella spiralis EN MODELO MURINO / Intestinal Trichinella spiralis Phase In Murine Model

Trichinella spiralis se encuentra principalmente en el hombre, rata, cerdo, perro; puede infectar a cualquier carnívoro u omnívoro. Cuando la carne o sus derivados están contaminados con larvas infectantes (LI) de T. spiralis y son ingeridas éstas pasan al estómago, donde sus cápsulas son disueltas por acción de los jugos gástricos, las larvas son liberadas en pocas horas, después pasan a la porción proximal del intestino delgado, donde se lleva a cabo su desarrollo. El objetivo del presente trabajo fue evaluar la fase intestinal de T. spiralis en un modelo murino. Un lote de 45 ratas Long Evans, se infectaron con aproximadamente 500 LI, y fueron sacrificadas tres diarias por 15 días. Se tomó un segmento de duodeno, yeyuno e íleon y se fijaron en formol al 10% para posteriormente ser procesados en parafina y teñido con hematoxilina-eosina. El resto del intestino delgado fue fraccionado, se incubó a 37 °C por dos horas y el sobrenadante se observó al microscopio de luz. Se encontró que el implante se lleva a cabo a nivel de yeyuno e íleon, que las hembras adultas dan origen aproximadamente 60-80 larvas recién nacidas (LRN), parto vivíparo en un tercio distal y subse-cuentemente son destruidas. Los machos adultos tienen espermatozoides no ciliados.

Trichinella spiralis is a parasitic disease in man, rat, pig, but can infect any carnivorous or omnivorous. When the meat or their derivates are contaminated with infective larvae (il) of T. spiralis pass to the stomach, their capsules are dissolved by the stomach juice, the larvaes are liberated in few hours, and then they pass to the near portion of the slim intestine in which they develop. The objective of the present work was to evaluate the intestine phase of T. spiralis in a murine model. Fourtyfive Long Evans rats were infected with 500 li approximately, then 3 rats were sacrificed everyday over a period of 15 days. A portion of duodenum, jejune and ileum were fixed in formaldehyde 10% and subsequently embeded in paraffin and dyed with hematoxilin-eosina. The rest of the slim intestine was cut and fractionated and incubated at 37 °c for 2 hours; the supernadant was observed unde light microscopy. We observed that the implant of larvae was in the jejune and ileum. The adult females gave origin to approximately 6080 newborn larvaes (LRN) and subsequently were destroyed. The adult male had non-ciliated sperm.
