RESUMEN

BACKGROUND: Cucurbita pepo (C. pepo) is cultivated and used traditionally as vegetable as well as medicine in different parts of the world. The aim of current study was to investigate the potential of C. pepo in attenuation of diabetic neuropathy via using streptozotocin (STZ)-induced diabetes model in male wistar rats. MATERIALS AND METHODS: Diabetic neuropathy was induced by administration of STZ; 65 mg/kg, i.p. and Nicotinamide (NAD; 230 mg/kg i.p.) and assessed by measuring thermal hyperalgesia, mechanical hyperalgesia and motor nerve conduction velocity (MNCV) in experimental animals. Treatment with different doses of (100, 200 and 400 mg/kg, p.o.) petroleum ether extract of C. pepo (CPE) and hydroethanolic extract of C. pepo (CHE) was started from the 60th day of STZ/NAD administration and continued upto 90th day. RESULTS: CPE and CHE significantly attenuated the behavioural changes including hyperalgesia, allodynia and MNCV linked to diabetic neuropathy. Moreover, the oxidative stress and level of TNF-α, TGF-ß and IL-1ß was found to be significantly attenuated in experimental animals. CONCLUSION: Thus C. pepo might ameliorate the progression of diabetic neuropathy via modulation of chronic hyperglycemia and therefore and have therapeutic potential for treatment of diabetic neuropathic pain.

RESUMEN

Diabetes has become more common in recent years worldwide, and this growth is projected to continue in the future. The primary concern with diabetes is developing various complications, which significantly contribute to the disease's mortality and morbidity. Over time, the condition progresses from the pre-diabetic to the diabetic stage and then to the development of complications. Years and enormous resources are required to evaluate pharmacological interventions to prevent or delay the progression of disease or complications in humans. Appropriate screening models are required to gain a better understanding of both pathogenesis and potential therapeutic agents. Different species of animals are used to evaluate the pharmacological potentials and study the pathogenesis of the disease. Animal models are essential for research because they represent most of the structural, functional, and biochemical characteristics of human diseases. An ideal screening model should mimic the pathogenesis of the disease with identifiable characteristics. A thorough understanding of animal models is required for the experimental design to select an appropriate model. Each animal model has certain advantages and limitations. The present manuscript describes the animal models and their diagnostic characteristics to evaluate microvascular diabetic complications.
