The interaction studies between five VAM fungi, i.e., Glomus mosseae, G. fasciculatum, G. constrictum, G. intraradices, Glomus spp. (local isolate), Acaulospora laevis and damping-off ischolar_main rot pathogen (Pythium aphanidermatum) along with fungicide (mancozeb + metalaxyl) check on tobacco (Nicotiana tabacum L.) seedbeds revealed that all the VAM fungi colonized the ischolar_mains efficiently within 30 days of inoculation. However, the per cent colonization was higher in the seedlings inoculated with local isolate Glomus spp. The per cent disease severity in 24 day old seedlings was significantly less in treatments with VAM fungi compared to non-mycorrhizal treatment. The disease severity in mycorrhizal seedlings ranged from 31.33 to 63.33, and it was 26.6 per cent in fungicide treatment and 100 per cent in non-mycorrhizal pathogen inoculated control seedlings. The minimum disease severity was observed in the fungicide treatment and in the seedlings inoculated with Glomus spp. The increase in plant growth characteristics such as seedling height, leaf area, fresh and dry weights of the seedling was significantly higher in pathogen inoculated mycorrhizal seedlings as compared to non-mycorrhizal pathogen inoculated seedlings. Total leaf cholorophyll content and nutrients N, P, K, Zn, Cu, Fe and Mn were higher in mycorrhizal seedlings compared to the non-mycorrhizal seedlings.Keywords

Twelve isolates of Streptomyces spp. from tobacco soils were screened for the production of antibiotics, of which two were found to be efficient. Growth pattern of the two potential isolates was studied and their antimicrobial activity was tested against Aspergillus flavus, A. niger, Pythium aphanidermatum, Bacillus subtilis and Pseudomonas fluorescens. Isolate 2 was found to be more effective and caused maximum inhibitory zone of 108 mm after 120 hrs against P. aphanidermatum. The area of the inhibitory zone observed in both the isolates was directly proportional to the age of the culture for up to 120h.Keywords

Carbamazepine is an anticonvulsant. It works by decreasing nerve impulses that cause seizures and pain. Carbamazepine is used to treat seizures and nerve pain such as trigeminal neuralgia and diabetic neuropathy. Carbamazepine is also used to treat bipolar disorder. Due to sudden onset of attack, it is necessary to formulate antiepileptics into such a delivery system, which provide immediate relief. Hence, the present investigation was undertaken with a view to develop mouth-dissolving tablets of Carbamazepine, which offers a new range of product having desired characteristics and intended benefits. In this study, the mouth dissolving tablets were prepared using two different technologies, direct compression method and solid dispersion technology. Tablets produced by direct compression method contain crospovidone as a super disintegrant and sorbitol as a sweetener. Solid dispersions of Carbamazepine with polyvinylpyrrolidone K-30 and polyethylene glycol 6000 in different weight ratios were prepared with a view to increase its water solubility. Carbamazepine solid dispersions with polyvinylpyrrolidone K-30 in 1:2 ratios of drug: carrier showed maximum drug release and hence, compressed along with other excipients into mouth dissolving tablet. The results compared for both the technologies showed that the Carbamazepine tablets prepared using solid dispersion technology was found to have good technological properties and satisfying and reproducible drug dissolution profiles. Moreover, the drug release was found to be comparable to the marketed dispersible tablet.Keywords
