Assam Agricultural University, Jorhat

Assam Agricultural University is the first institution of its kind in the whole of North-Eastern Region of India. The main goal of this institution is to produce globally competitive human resources in farm sectorand to carry out research in both conventional and frontier areas for production optimization as well as to disseminate the generated technologies as public good for benefitting the food growers/produces and traders involved in the sector while emphasizing on sustainability, equity and overall food security at household level. Genesis of AAU - The embryo of the agricultural research in the state of Assam was formed as early as 1897 with the establishment of the Upper Shillong Experimental Farm (now in Meghalaya) just after about a decade of creation of the agricultural department in 1882. However, the seeds of agricultural research in today’s Assam were sown in the dawn of the twentieth century with the establishment of two Rice Experimental Stations, one at Karimganj in Barak valley in 1913 and the other at Titabor in Brahmaputra valley in 1923. Subsequent to these research stations, a number of research stations were established to conduct research on important crops, more specifically, jute, pulses, oilseeds etc. The Assam Agricultural University was established on April 1, 1969 under The Assam Agricultural University Act, 1968’ with the mandate of imparting farm education, conduct research in agriculture and allied sciences and to effectively disseminate technologies so generated. Before establishment of the University, there were altogether 17 research schemes/projects in the state under the Department of Agriculture. By July 1973, all the research projects and 10 experimental farms were transferred by the Government of Assam to the AAU which already inherited the College of Agriculture and its farm at Barbheta, Jorhat and College of Veterinary Sciences at Khanapara, Guwahati. Subsequently, College of Community Science at Jorhat (1969), College of Fisheries at Raha (1988), Biswanath College of Agriculture at Biswanath Chariali (1988) and Lakhimpur College of Veterinary Science at Joyhing, North Lakhimpur (1988) were established. Presently, the University has three more colleges under its jurisdiction, viz., Sarat Chandra Singha College of Agriculture, Chapar, College of Horticulture, Nalbari & College of Sericulture, Titabar. Similarly, few more regional research stations at Shillongani, Diphu, Gossaigaon, Lakhimpur; and commodity research stations at Kahikuchi, Buralikson, Tinsukia, Kharua, Burnihat and Mandira were added to generate location and crop specific agricultural production packages.

    COMPARATIVE EVALUATION OF NANOSILVER, UNPASTEURIZED HONEY AND TURMERIC IN THE TREATMENT OF FULL THICKNESS CONTAMINATED CUTANEOUS WOUND IN RABBITS
    (Assam Agricultural University, Khanapara, Guwahati, 2016-07) PRADHAN, EKTA; Sarma, K. K.
    The present study was carried out on experimentally created full-thickness contaminated cutaneous wounds in New Zealand White rabbits with an aim to evaluate the healing efficacy of nanosilver, unpasteurized honey and turmeric. The experiment was carried out on 15 apparently healthy New Zealand White rabbits of either sex, divided into 3 equal groups. Full-thickness cutaneous wounds of 4x4 cm were created on the thoraco-lumbar region on either sides of the vertebral column under general anaesthesia and were left unattended for 48 hours to render it contaminated. Group A, Group B and Group C were subjected to ‘Silverkind Nanofine’ (nanosilver), unpasteurized honey and turmeric paste respectively. The rate of wound healing and macroscopic changes were recorded on the 3rd, 7th, 10th, 15th and 20th days of post wound creation. The bacteriological and biochemical investigation were performed on the 3rd, 5th, 7th and 10th days of post-wound creation and the histopathological investigations on the 3rd, 10th and 28th days of experiment. The rate of wound healing was found to be the fastest in nanosilver treated group, followed by the ones with unpasteurized honey and turmeric till the 28th day of experiment. Various macroscopic changes were observed during the course of treatment viz. peripheral swelling, serous exudation, dry casts over the wound, proliferating pinkish granulation tissue and fast contracting wound edges with re-epithelialization. However, clinically complete wound healing was observed on the 20th day of post-wound creation in Group A. The bacteriological investigation revealed presence of coagulase positive Staphylococcus spp., coagulase negative Staphylococcus spp. and Escherichia coli at the initial stages and eventually became a sterile wound by the 10th day of post-wound creation in both nanosilver based ointment and unpasteurized honey. Higher levels of total protein and carbohydrate were observed in Group B and Group C while the enzymatic investigations revealed decreasing levels of creatine kinase and aspartate aminotransferase which was more significant in Group A (P<0.01). The histopathological studies on the 28th day of post-wound creation revealed clinically complete healing in Group A with regeneration of all the epidermal layers and associated adnexa and better reorganization of the thick collagen bundles. From the above findings, it could be drawn that use of nanosilver based ointment was found to more effective in terms of wound healing of contaminated cutaneous wounds compared to the other two treatment regimes.
