To predict the behaviour of selections in the F 1 generation itself before taking them to the advanced generations for further screening, the applicability of diallel cross analysis was studied .For this purpose four N. tabacum varieties were crossed in all combinations to constitute a diallel system and data collected on green leaf, saleable leaf i .e . sum of bright leaf and medium leaf yields, number of days taken for flowering, length and breadth of the middle leaves at maturity of the F l plants were subjected to JINKS and HAYMAN method of analysis .The results showed that Delcrest is a good combiner in throwing better recombinations . It always improved the yielding potential of the poorer parent . In the light of the graphical analysis, the results were discussed in relation to the improvement of the crop and predictions made as to which cross throws better strains . The characters studied are mostly additive in gene action . The scope of this method in the breeding projects to evolve superior strains was outlined .

Gingival crevicular fluid (GCF) is an inflammatory exudate that can be collected at the gingival margin or within the gingival crevice. The biochemical analysis of the fluid offers a non invasive means of assessing the host response in periodontal disease. Active phase of periodontal disease process can be measured or assessed by the constituents of gingival fluid. Bacterial enzymes, bacterial degradation products, connective tissue degradation products, host mediated enzymes, inflammatory mediators, extracellular matrix proteins either together or individually can be detected in higher levels in gingival crevicular fluid during active phase of periodontitis.

Amoebic liver abscess is one of the important diseases in tropical third world counties, especially in certain areas where the people drink Toddy an alcoholic beverage extacted from palm trees, it's available in certain seasons, in these seasons especially late summer to early rainy months the prevalence of Amoebic liver abscess is high, young to middle aged men are more affected than women, since there are many factors why the women are less likely get this disease.

The syndrome of intracranial venous sinus thrombosis termed as cerebral venous thrombosis is a distinctive cause of cerebrovascular disease in the young. CVT has been diagnosed almost exclusively at autopsy. However, with the advent of modern neuroimaging techniques, the quantum of CVT cases being diagnosed has increased significantly when compared to previous years. The annual incidence is currently estimated to be 3-4 cases for one million people. It accounts for 10% to 20% of the etiology of young stroke in India. 1 CVT is now typically recognized as a disorder with various clinical presentations and usually favorable outcome. Magnetic resonance imaging and magnetic resonance angiography are the best diagnostic methods available for diagnosis of CVT, and heparin is the first line treatment. But as the symptoms, modes of onset, and neuroimaging methods are diverse, the diagnosis of CVT is commonly overlooked. Pathological hallmark of CVT is hemorrhagic infarction. CVT is primarily a disease of a young man, can present in protean ways with a wide spectrum of clinical manifestations. These include headache, altered sensorium, seizures, focal neurological deficits, papilledema and cranial nerve palsies. The commonest dural venous sinuses involved are superior sagittal sinus and transverse sinus. Nearly 20% of cases of CVT are idiopathic in origin. However, in the Asian Studies, infectious puerperium seems to be the commonest cause of CVST. Though stroke due to arterial thrombosis is more common, cerebral venous sinus thrombosis especially in young strokes. The clinical and neurological presentation can be variable, hence there needs to be a high index of suspicion for venous sinus thrombosis in order to diagnose this entity clinically. There is a wide spectrum of underlying causes of this condition. The prognosis is good, especially when the diagnosis is prompt and treatment initiated. The aim of this study is to study the clinical profile of cerebral venous sinus thrombosis, to study the etiology factors of cerebral venous sinus thrombosis, to correlate the severity and clinical presentation with imaging studies to study the outcome at discharge and at follow-up if possible.
