  Delayed hypersensitivity reaction was used to measure the cell mediated immunity against avian coccidiosis. There was a gradual increase in the comb thickness of the immunized birds of all the groups from 24 to 72 hours after intradermal injection. The mean difference in comb thickness before and after injection of the respective antigen for the group immunized with Vaccine I (sonicated supernatant) was 1.87 mm at 24 hours, 2.23 mm at 36 hours, 2.31 mm at 48 hours and 2.42 mm at 72 hours. There was a significant difference (p<0.01) in comb thickness at 24 and 36 hours after intradermal injection. The mean difference in comb thickness before and after injection of the respective antigen for the group immunized with Vaccine II (sonicated sediment) was 1.12 mm at 24 hours, 1.75 mm at 36 hours, 2.10 mm at 48 hours and 2.31 mm at 72 hours. The difference was significant (p<0.01) at 24 and 48 hours; 36 and 72 hours after injection. Maximum difference in comb thickness was recorded 72 hours after injection in birds immunized with Vaccine I. It appears that delayed hypersensitivity response to sonicated supernatant antigen reported herein represent a strong CMI reaction. Delayed hypersensitivity comb reaction is a quick, simple, economical and practical tool to routinely determine the immune status of a bird with out restoring to challenge.

  Present research work was conducted to study the clinical efficacy of coded herbal medicine Kemol in comparison with Piperazine for treatment of intestinal worm infestation. One hundred patients with intestinal worm infection were randomly assigned into two groups, 50 in each group. Test group was treated with Kemol and control group was treated with Piperazine. The effect of both drugs for treatment of intestinal worm infestation was observed before and after treatment. Comparison of data recorded by physician relating to these variables showed significant differences between test and control groups (p<0.05). The efficacy of the test treated medication (Kemol) was superior as p = 0.03. Kemol is more effective than the Piperazine in the treatment of intestinal worms.

  Background: The most commonly used plant namely Onosma khyberianum was brought under antimicrobial study after observing their medicinal values. The present study aim to assess antimicrobial activity of ethanolic extracts and subsequent solvent soluble fractions of Onosma khyberianum against five bacterial strains Salmonella typhi, Shigella dysenteriae, Escherichia coli, Staphylococcus aureus, Vibrio cholerae and three fungal strains Aspergilus flavus, Alternaria alternate and Fusarium oxysporum. Materials and Methods: Briefly the stock solution of crude extract and other fractions were prepared in DMSO (3 mg mL-1 for antibacterial essay, 4 mg 1 mL-1 for antifungal essay). The antibacterial activity was evaluated by agar diffusion method while for antifungal assay the disc diffusion method was used. Results: The ethanolic and chloroform fractions showed excellent activity against all the selected bacterial strains. The same fractions also showed best activity against all selected fungal strains. Conclusion: The present study suggests Onosma khyberianum to be a source for isolation of antimicrobial compounds for human health care and use as preservatives in food processing industries.
