Five fungicides such as rovral, bavistin, cupravit, dithane M-45 and thiovit were tested against conidial germination of Fusarium oxysporum. Dithane M-45 was the most effective against the fungus. Rests of the fungicides were more or less effective in the inhibition of conidial germination after 5~30 minutes immersion in 500~2500 ppm concentration. Five plant extracts(leaf extracts of Ocimum sanctum, Lantana camera, Calotropis procera, Azadirachta indica and Vinca rosea) found to be more or less effective against the fungus. 'Dhup' somke have good inhibitory effect on conidial germination of F. oxysporum.

A newly synthesized Nickel (II) tyrosine complex was screened as potential antimicrobial agent against a number of medically important bacteria (Bacillus subtilis, Streptococcus beta-haemolytica, Escherichia coli, Shigella dysenterae) and fungi (Aspergillus fumigatus, Candida albicans, Aspergillus niger, Aspergillus flavus, Penicillium sp.) strains. were used for antifungal activity. The antimicrobial activity was evaluated using the Agar Disc method. Moreover, the minimum inhibitory concentration of the complexes was determined against the same pathogenic bacteria and the values were found between 4~64 microg ml(-1). Brine shrimp bioassay was carried out for cytotoxicity measurements of the complexes. The LC50 values were calculated after probit transformation of the resulting mortality data and found to be 6 microg ml(-1).

The levels of tartrate resistant acid phosphatase (TRAP), matrix metalloproteinase-2 (MMP-2), and tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) in synovial fluid (SF) and serum in cases of canine osteoarthritis (OA) were measured. OA was induced by a surgically-created medial patellar luxation in the left stifle of 24 dogs. SF and blood samples were collected at 1.5- and 3-month intervals, respectively. Every 3 months, one dog was euthanatized to collect tissue samples from both stifles. TRAP levels in SF and serum were measured using a spectrophotometer, and TRAP-positive cells in joint tissues were identified by enzyme histochemistry. MMP-2 and TIMP-2 in SF and serum were detected by Western blotting and ELISA, respectively. TRAP in SF from the stifles and serum was significantly increased (p < 0.05) after 3 months. TIMP-2 in SF and serum was significantly decreased (p < 0.05), whereas MMP-2 in SF was significantly increased (p < 0.05) during the progression of OA. Histochemistry revealed an increased number of TRAP-positive cells in tissues from OA-affected joints. Assays measuring TRAP, MMP-2, and TIMP-2 in SF and serum, and methods that detect increased numbers of TRAP-positive cells in the joint tissues can play an important role in identifying the early phases of degenerative changes in canine joint components.

An intact male German shepherd dog (4 y, body wt. 35.5 kg) was referred to the Animal Medical Center, Chonbuk National University with severe lameness, pain and gait abnormality on the right hind limb. Survey radiographs of the pelvis revealed dysplasia of the right coxofemoral joint with subluxation. The dog was surgically treated performing total hip replacement (THR) using Modular Biolox Canine Modular THR System. The dog began to bear weight and slowly returned to a normal exercise pattern 2 months after surgery. THR resulted in satisfactory clinical functions with 6 months follow up and no complications were observed. Canine modular THR could be a successful modality for the management of disabling conditions of the coxofemoral joint.

Effect of ethanolic extracts of Lawsonia inermis, Azadirachta indica, Vinca rosea, Tagetes patula, Ocimum sanctum, Colocasia antiquorum, Adhatoda vasica, Moringa oleifera, Datura metel and Curcuma longa leaf on conidial germination, mycelial growth and sporulation of Aspergillus flavus, A. niger and A. fumigatus were examined. The conidial germination of A. flavus and A. fumigatus were most inhibited by the extract of L. inermis, while that of A. niger was inhibited by A. indica. Other tested plant extracts have a good effect on conidial germination on the selected fungi. The highest mycelial growth of A. flavus (37 mm) was found in V. rosea, but in case of A. niger and A. fumigatus it (38 and 39 mm) was found in D. metel. The lowest (4, 9 and 6 mm) respectively mycelial growth of these fungi found in L. inermis. The highest sporulation (75 x 10(4)/ml) of A. flavus was counted in V. rosea, but in case of A. niger and A. fumigatus those (45 x 10(4) and 55 x 10(4)/ml) were in D. metel and the lowest (5 x 10(4), 12 x 10(4) and 9 x 10(4)/ml) respectively sporulation of these fungi counted in L. inermis plant extract medium.

Twenty plant extracts were tested against mycelial growth, sclerotium formatiom and dry weight of mycelium with sclerotia of Sclerotium rolfsii Sacc. The highest(90 mm) mycelial growth was measured in Adhatoda vasica, Tegetes erecta, Allium cepa, and Curcuma longa. The lowest(25 mm) was in Azadirachta indica. No mycelial growth was found in any concentration of cow, buffalo, and goat urine. The highest(90 mm) and the lowest(15 mm) mycelial growth were measured in Biomil and Urea, respectively. No mycelial growth was observed in Zinc. The highest(60 mm) and the lowest(2 mm) mycelial growth were recorded in Macuprex(Dodine; 65% WP) and Boron(100% Boric acid and 17% Boron) respectively. Mycelial growth was totally inhibited in Rovral(Iprodione; 50% WP).
