background and objectives: studies have documented the morhplogical, neurochemical and functional difference between the dorsal and ventral zones of hippocampus. the aim of this study was to assess the effects of chronic diabetes mellitus type1 on ventral and dorsal zones of hippocampus. methods: experimental diabetes was induced by stereptozotocin at a dose of 60 mg/kg. at the end of 8 weeks ...
background: axotomy causes sensory neuronal loss. reconnection of proximal and distal nerve ends by surgical repair improves neuronal survival. it is important to know the morphology of primary sensory neurons after the surgical repair of their peripheral processes. methods: animals (male wistar rats) were exposed to models of sciatic nerve transection, direct epineurial suture repair of sciati...
neurite outgrowth from dorsal root ganglion (drg) explants is a method of evaluating neurotrophic activity of growth factors. when complete medium containing collagen was supplemented with nerve growth factor (ngf) drg outgrowth was observed after 18 h. in the absence of ngf and in the presence of collagen, the drg outgrowth took place after 72 h. in wells not supplemented with collagen gel in ...
به دلیل اهمیت بسیار زیادی که ساختار عروقی در بررسی پاتوژنز بیماری هایی مانند لامینیت ( (laminitis و زخم کف سم دارد، شناخت این ساختارها کاملاً ضروری به نظر می رسد. مقالات منتشر شده در مورد ساختار عروقی در گوسفند اندک است. اندام خلفی 15 بره 3 ماهه از محل مفصل تارس جدا شد. با جدا کردن سرخرگ dorsal metatarsal artery ابتدا سالین جهت شستشو و سپس رزین متاکریلات برای تشکیل کست تزریق شد. سرخرگ های dorsal...
Introduction: In the present study, the effect of inhibition of glutamate NMDA receptors located in the dorsal hippocampus on the maintenance of anxiety and depression like behaviors induced by electric foot shock stress was investigated. Materials and Methods: NMARI male mice were divided into two categories. The first category received electro foot shock for 30 minutes after injection of mema...
the importance of vessel structure has been shown in pathogenesis of the equine and bovine laminitis. investigation on vessel structures is necessary to diagnose the mechanism of laminitis. due to lack of literature on ovine digital arteries. ovine digital vessels were studied using corrosion casting method. the hind limbs of 15 lambs of 3 months ages were separated from tarsus joint. after the...
soil-dwelling mites and among them gamasina (acari, mesostigmata) are widely distributed in soils, rich in species and have great ecological significance in the respective ecosystems. a survey was conducted to study laelapidae (mesostigmata) mites in ahwaz (khuzestan province), iran during 2010-2012. samples were taken from soil and litters and then mites extracted using berlese funnel, cleared...
Dorsal agenesis of the pancreas is a very rare congenital anomaly with less than 100 cases reported in world literature till 2020. associated pancreatic tumors extremely rare; only 17 have been to date. Here we case dorsal mixed carcinoma pancreas.
Background and purpose: The adrenergic system is known to have modulatory influence on anxiety-related behaviour both in human and animals. Dorsal hippocampus is an important brain site in modulation of neurotransmittery and neuroendocrinology of anxiety. The present study, was designed to evaluate the interactions between adrenergic and opioidergic systems in dorsal hippocampus on anxiety. Ma...
