The antiviral activity of plants Glyceriza glabra (roots), Phyllanthus amblicus (Fruit), Eugenia jamolana (Leaves), and Moringa oleifera (Leaves) were evaluated against Infectious bursal disease virus (IBDv) in this study. Ethanolic extraction of these plants was carried out by using Soxhlet apparatus. Four dilutions of each extracts viz 100, 50, 25 and 12.5 g/ml were made. Vero cells were infected by identified infectious bursal disease for antiviral assay. Dilutions of these extracts were applied in triplicate manner on Vero cells (infected by IBDv), that are confluent in 96 well cell culture plates. The cytotoxic activity of mentioned plant extracts was carried out by treating the cells by the same dilutions as used in antiviral assay and incubated the both 96 well cell culture plates for four days. After this incubation, viability of cells was determined by MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] colorimetric assay. Endpoint of these assays was measured in terms of cell survival percentage. Results were compared for qualitative variables using Chi-square technique and quantitative variables by linear regression analysis.

Aseptic arthritis of the knee joint was induced in 12 healthy donkeys, weighing 60 to 85kg by intra- articular injection of 0.3ml of turpentine oil. The animals were randomly divided into 2 groups A and B of 6 animals each. Group A served as a control whereas in Group B anti-arthritic drug, diclofenac sodium (Diclocare 5%) was administered intramuscularly at the dose rate of 2.5mg/kg body weight daily for 5-6 days starting one day after the induction of arthritis. In group B, the joint circumference became normal on 6th day after induction of arthritis while in group A (control), the joint circumference took 16 to 20 days to become normal. According to this trial, diclofenac sodium provided an early return to normal stance and weight bearing in treated group B, taking longer time in control group A. No significant change in blood Haemoglobin, Total erythrocyte count, Total leukocyte count, Erythrocyte sedimentation rate and Packed cell volume was observed in control and treated animals. It is concluded that diclofenac sodium is an effective treatment for arthritis in donkeys.
