“…A question has been raised as to whether nutritional intervention can prevent chronic pain development. 312 , 313 , 314 , 315 A number of dietary phytochemicals possess anti‐oxidant and anti‐inflammatory properties and have been shown to have tissue and disc cell protective properties in‐vitro. Flavonoids have potent anti‐oxidant and anti‐inflammatory cell and tissue protective properties.…”

The purpose of this review was to evaluate data generated by animal models of intervertebral disc (IVD) degeneration published in the last decade and show how this has made invaluable contributions to the identification of molecular events occurring in and contributing to pain generation. IVD degeneration and associated spinal pain is a complex multifactorial process, its complexity poses difficulties in the selection of the most appropriate therapeutic target to focus on of many potential candidates in the formulation of strategies to alleviate pain perception and to effect disc repair and regeneration and the prevention of associated neuropathic and nociceptive pain. Nerve ingrowth and increased numbers of nociceptors and mechanoreceptors in the degenerate IVD are mechanically stimulated in the biomechanically incompetent abnormally loaded degenerate IVD leading to increased generation of low back pain. Maintenance of a healthy IVD is, thus, an important preventative measure that warrants further investigation to preclude the generation of low back pain. Recent studies with growth and differentiation factor 6 in IVD puncture and multi‐level IVD degeneration models and a rat xenograft radiculopathy pain model have shown it has considerable potential in the prevention of further deterioration in degenerate IVDs, has regenerative properties that promote recovery of normal IVD architectural functional organization and inhibits the generation of inflammatory mediators that lead to disc degeneration and the generation of low back pain. Human clinical trials are warranted and eagerly anticipated with this compound to assess its efficacy in the treatment of IVD degeneration and the prevention of the generation of low back pain.

An update on animal models of intervertebral disc degeneration and low back pain: Exploring the potential of artificial intelligence to improve research analysis and development of prospective therapeutics

Animal models have been invaluable in the identification of molecular events occurring in and contributing to intervertebral disc (IVD) degeneration and important therapeutic targets have been identified. Some outstanding animal models (murine, ovine, chondrodystrophoid canine) have been identified with their own strengths and weaknesses. The llama/alpaca, horse and kangaroo have emerged as new large species for IVD studies, and only time will tell if they will surpass the utility of existing models. The complexity of IVD degeneration poses difficulties in the selection of the most appropriate molecular target of many potential candidates, to focus on in the formulation of strategies to effect disc repair and regeneration. It may well be that many therapeutic objectives should be targeted simultaneously to effect a favorable outcome in human IVD degeneration. Use of animal models in isolation will not allow resolution of this complex issue and a paradigm shift and adoption of new methodologies is required to provide the next step forward in the determination of an effective repairative strategy for the IVD. AI has improved the accuracy and assessment of spinal imaging supporting clinical diagnostics and research efforts to better understand IVD degeneration and its treatment. Implementation of AI in the evaluation of histology data has improved the usefulness of a popular murine IVD model and could also be used in an ovine histopathological grading scheme that has been used to quantify degenerative IVD changes and stem cell mediated regeneration. These models are also attractive candidates for the evaluation of novel anti‐oxidant compounds that counter inflammatory conditions in degenerate IVDs and promote IVD regeneration. Some of these compounds also have pain‐relieving properties. AI has facilitated development of facial recognition pain assessment in animal IVD models offering the possibility of correlating the potential pain alleviating properties of some of these compounds with IVD regeneration.

Natural plant-derived compounds have been an essential resource in the evolution of drug discovery since the dawn of time. Using plants as a source of medicine is a century-long-standing tradition not merely in India but also in the entire world. North-East India is bestowed with incredible biological richness. The current research is focused on the histological and phytochemical analysis of four potent plant species collected from Goalpara district of Assam that is widely used in treating skin disorders. The four medicinal plants were collected based on traditional knowledge. The plants were evaluated for the identification and histochemical localization of effective phytochemicals following the standard protocols. Qualitative phytochemical analysis revealed the presence of important phytoconstituents responsible for different biological activities, including dermal activity. The histological study further showed the localization of phytochemicals, alkaloids, terpenoids, tannins, phenolics and flavonoids in all four plants. From adults to neonates, skin disorders are a major problem, especially in developing countries. Dermatological problems often deal with costly medications. The present study indicates that the studied plant species could be a dynamic avenue for isolating bioactive chemicals, and novel therapeutics can be developed to combat dermatological problems with potential and cost-effective solutions. INTRODUCTION:Nature acts as an effective chemist of humankind. Though a vast quantity of plant species was explored, the pharmacognosy of many plant-derived compounds is still untouched and beyond the imagination of even our best researchers 1, 2 .
