    Percutaneous Transfixation for long Bone fracture in Goats -A- Modified Technique
    (Birsa Agricultural University, Ranchi, 2001) Himanshu Singh; P.N.Sahay
    1. This technique of transfixation provides an effective means of accurate reduction and rigid fixation of long bones without any danger of slough or chafing. 2. Both the fragments of the fractured bone are virtually locked by this fixation device, hence the possibility of rotation of distal fragment is eliminated in large majority of the cases. 3. The whole set-up provides free access to the traumatized bone, so this technique is particularly efficacious for compound fractures and those fractures of limbs which have been severely denuded. 4.During the healing phase of osseous defect, free use of the affected limb is facilitated due to lightness of the fixation device and non-involvement of the preceeding and succeeding joints. 5. Four pin assembly is markedly superior to 3 pin assembly in terms of carly accomplishment of pain free mobility, weight bearing and radiographic evidence of healing. 6. healing. Stainless steel Steinmann pins can be safely employed for transverse placement in the predrilled ossous bore canals without the risk of impairing the functional status of the bone, if strict aseptic precautions are observed. 7. Aluminium template connecting bar of 1 mm thickness would be more suited in the endeavour like this in goats of heavier size in comparison to the one of 0.56 mm thickness used in the present study

    Experimental Studies on the Reconstruction of Urinary Bladder with Biological Auto and Allografts in Buffalos Calves
    (Birsa Agricultural University, Ranchi, 1993) Mohammad Ehasan; A. A. Khan
    On the basis of the findings of the present experimental endeavor, the following conclusions may be derived: 1.The methodology of cystoplasty in the present study appears to be convenient and can be accomplished with ease even at centers with limited technical facility and expertise. 2.Easy availability of the biological materials make the endeavor suitable for wider adaptation. 3. The potential of glycerol as an appropriate preservative material for homologous biological tissue seems beyond conjecture. 4. Homologous urinary bladder and pericardial sacs have a longer shelf-life under preservation and hence can be used safely under field conditions, without any deterioration in their quality for at least three months. 5. Reconstitution of bladder with these biological materials did not alter the functional status of the organ to any greater extent in the immediate post-operative phase and there after. Of the three materials used, preserved bladder incited least functional alterations. 6. Crafting of allogeneic and autogenic biological materials induces changes in the biochemical profile of the blood. However, these changes, manifested as elevation of some blood. Chemicals were transitory and inconsequential as normalcy was restored by 120 hours of cystoplasty.

    Comparative Evaluation of Colonic Anastomosis by Monolayer Appositional techniques Alongwith Appraisal and Management of Post – Operative Abdominal Adhesions in Canine
    (Birsa Agricultural University, Ranchi, 1993) Rudradev Mukherjee; U.K. Deokiouuliyar
    1. Monolayer appositional technique of colonic anastomosis is efficacious, safe, easily accomplishable and devoid of post-operative anastomotic complication. 2. Both the suturing patterns-continuous and interrupted, are appropriately poised to be adopted for routine clinical application for entero-anastomosis by this technique. 3. Comparative evaluation of the suturing patterns establishes the superiority of continuous fashion over interrupted one on the basis of anastomotic time and consumption of valuable suturing material, both being lesser in the former pattern. 4. Abdominal surgery is associated with the development of the post-operative intraperitoneal adhesions with varying intensities even in response to the similar nature of surgical stress to the mesentery. 5. Mast cells are actively related with the adhesion formation-greater rupture of these cells can be correlated with higher grade adhesions.

    STUDIES ON HERNIOPLASTY WITH BIOLOGICAL AND NON -BIOLOGICAL IMPLANTS IN BOVINE
    (Birsa Agricultural University, 1985) DEOKIOULIYAR, UPENDRA KUMAR; KHAN, A.A.
    1. Preserved homologous pericardium appeared to be a very promising material for tissue substitute in the repair of large abdominal hernias. 2. The autogenous full-thickness free skin implant can be used for this purpose but the feasibility of infection in sporadic cases cannot be ruled out. 3. Large hernias repaired with these biological tissues appeared resistant to natural strains. 4. No cyst formation vas observed macroscopically and microscopically. 5. Epidermis and epidermal elements degenerated and showed complete desquamation, the process being earlier with inlay technique. Graft appeared to be metamorphosed by sixteen weeks. 6 With only skin graft the development of a thick fibrocellular layer due to better proliferation of fibroblasts appeared to be an added advantage. 7. Preserved pericardial tissue seemed to be tolerated well and no evidence of rejection by the host animal was discernible.

    COMPRESSION OSTEOSYNTHESIS FOR LONG BONE FRACTURES IN GOATS
    (Birsa Agricultural University, 1985) BUCHOO, BASHIR AHMAD; Sahay, P.N.
    From the results of the present study, the following conclusions have been drawn: 1. Bony union is almost complete after 4th week with compression plating whereas plaster cast immobilization is not capable of oblicorating the fracture gap completely even up to 6th wook. 2. Plantar cast immobilization results in a number of post-operative complications like stiff joints, munale atrophy and infection like problems. On the contrary pain-free mobilization of joints and muscles with the use of ompression plating eliminates much complications, enables early ambulation and rapid recovery. Moreover, easy approach to the wound in the soft tissus enables the post-operative care of the compound fractures easier and thus limit the chances of post-operative infection. 3. stable and rigid fixation offered by compression plating reduces the chances of failures during fracture healing. Contrarily planter cast provides inadequate immobilisation resulting into displacement and over-ridding followed by non-unions. 4. Compression plating eliminates inter-fragmental movement between the fractured ends and results in primary bona healing and full, active pain-free mobilization of the affected limb. Relative movement between the fractured bona fragments due to inadequate stabilization by plastar cast indudas massive callus formation, regarded as a teloid of the bone. 5. The concept that compression plating promotes osteogenesis and thereby shortens healing period has been appropriately vindicated by the results of the present study. 6. Compression plating technique for fracture repair appears to be an ideal method for the radial and ulnar fractures in goats.

    CLINICO- BIOCHEMICAL ALTERATIONS AND EFFICACY OF PERITONEAL LAVAGE IN BOVINE PERITONITIS
    (Birsa Agricultural University, 1983) MOHANTY, DEBABRATA; Sahay, P.N.
    . Diffuse peritonitis resulting from bacterial and chemical irritants is highly fatal in cattle. 11. Vigorous, aggressive therapy is necessary to overcome the physiologic alterations associated with diffuse peritonitis. 111. The disease develops progressively and is characterized clinically by elevated body temperature, pulse and respiration, leukocytosis vith shift to left and haemoconcentration. iv. Significant hypoglycemia and increased plasma protein and B.U.II. levels are biochemical features of the late peritonitis in cattle. v. The disease can be effectively combated with peritoneal lavage and systemic antibiotic therapy administered together. vi. Either of systemic antibiotic or peritoneal lavage therapy alone in inadequate for this malady. However, the latter is superior comparatively. vii. Lavage fluid consisting of normal saline solution and local antibiotic is efficacious for the irrigation of peritoneal cavity. viii, Closed method of intermittent lavage is safe, easier, quicker to perform and devoid of c

    TENOPPHAPHY OF NEGLECTED RUPTURE OF TENDO ACHILLES IN CANINES -AN EXPERIMENTAL STUDY
    (Birsa Agricultural University, 1984) Sharma, JITENDRA; KHAN, A.A.
    1. Functional limb usage is earlier in cases repaired with fascial strips than those where tenoplasty is effected using tendon strip or Bunnell-Mager suturing. 2. The external immobilization of the limb appears to be essential for a minimum period of six weeks where tendon strip and stainless steel wire are used in cases of delayed repair. 3. The Range of Motion of hock joint is directly proportional to the extent of adhesions around the repaired tendo Achilles. 4. An increase in ROM does not always show an improvement in functional limb usage, if the weight bearing on the affected limb in partial or absent. 5. The greater is the trauma to the tendon and surrounding tissues the greater are adhesions as revealed by fasciagraphy. 6. All the grafts are taken up by the host tendons and there is no rejection when fresh and autogenous fascia lata or tendon strip graft are used. 7. Repair in neglected cases with a combination of fascial strips between stumps and fascia lata sheet around the gapping ends provides superior performance in terms of histopathological findings of healing and clinical features. 8. Autogenously tendon strip and fascia lata cuff when used together are comparatively slow to effect union between tendon ends. 9. Where only stainless steel wire and a fascial cuff are used in unapposed tendon ends, the healing is slower than where a strip of tendon or fascial strips are interposed between tendon ends. 10. The new fibrous tissue proliferation with mature fibroblast cells growing from the fascial cuff and surrounding tissues towards tendon junction supports the earlier findings that the healing in tendons is from without inwards. 11. At four weeks, the fate of fascial strips and tendon strip is not ascertainable histopathologically or by gross examination. 12. The fascial cuff begins to separate six weeks after repair and the tubular fascial graft remains viable till six weeks. 13. Silk appears to provoke higher cellular reaction than stainless steel wire, while the latter may incite mechanical irritation in isolated cases.

    COMPARATIVE EVALUATION OF HETEROGENOUS BONE PLATING AND NEUTRATIZATION PLATING FOR REPAIR OF FEMUR FRACTURE IN GOATS
    (Birsa Agricultural University, 1984) MOULVI, BASHIR AHMAD; SAHAY, P.N.
    1. Bone plates can be prepared from the cortical portion of adult bovine ribs and may be used successfully for the repair of femur fracture in goats. 2. Chemical treatment of bone plates sequentially with hydrogen peroxide and ether makes them appropriate for heterogenous use. 3. With heterogenous bone plating optimal healing is discernible by 4 weeks while with neutralization plating the process appears to be incomplete even by six weeks, thus the former reduces the period of repair. 4. The feasibility of failure with single plating is very less with heterogenous bone plate than with neutralization plate. 5. Neutralization plates cause thinning of the cortex and hence the bone has to be protected after removal of the plate to prevent fatigue fracture. 6. Serum alkaline phosphatase activity reaches the peak in 21 days after which it gradually decreases to near normal by 42 days. And on 42 days there is 14.26% decrease of the peak value. These changes are independent of the materials used for immobilization. 7. The concept that fracture healing process is stimulated by heterogenous bone plate has been confirmed by the results of this study.
