A STUDY OF IMMUNOHISTOCHEMICAL EXPRESSION OF GALECTIN-3 IN NON-NEOPLASTIC AND NEOPLASTIC LESIONS OF THYROID

Introduction: Thyroid lesions are fairly common and have a wide spectrum of diseases ranging from functional, immune mediated to neoplastic lesions. Malignancy of thyroid constitutes approximately 1% of all cancers. These malignant tumors of thyroid gland exhibit a variety of histopathologies and clinical behavior. Immune markers are gaining more and more importance in diagnostic pathology, especially in the differential diagnostics and in the grading of thyroid gland tumors. In the recent times Galectin-3 has received notable recognition for its usefulness as a diagnostic marker for thyroid cancer. To evaluate the diagnostic role of galectin-3 (Gal-3) in Aims and objectives: differentiating malignant from benign thyroid neoplasm. In this observational study, we evaluated Gal-Material and method: 3 expression in a spectrum of all non-neoplastic and neoplastic lesions including benign and malignant lesions of thyroid gland. All types of thyroidectomy specimens were xed in 10% formal saline and subjected to histopathological examination. Sections were stained with H&E stain. Gal-3 immunoperoxidase reaction was carried out in histological sections from all the cases and descriptive analysis was done. In the study of 100 cases of thyroid swelling were included and evaluated by Result: histopathological and by using Gal-3 immunoperoxidase marker. Out of 100 cases, majority of thyroid lesions were seen in females with 76 cases (76%) while only 24 cases (24%) were seen in male. Among 66 non-neoplastic cases, only 6 cases (9.1%) and among 34 neoplastic lesions, 28 cases (82.4%) were positive for galectin-3 marker. Statistical signicance of galectin-3 expression between non-neoplastic and neoplastic thyroid lesions found to be statistically signicant (P value <0000.1). The sensitivity and specicity of galectin-3 detection of malignant lesions were found to be 82.4% and 91% respectively with 82.4% positive predictive value and 90.9% negative predictive value. We suggest that Galectin-3 expression is helpful in Conclusion: enabling better diagnosis and patient care by guiding appropriate therapeutic decisions.

All Gene Expression of Leukotriene A4 Hydroxylase (LTA4H ) Gene in Extra Pulmonary Tuberculosis Patients and Healthy Control in North Indian Population

Initial diagnosis and timely treatment of Extra Pulmonary Tuberculosis (EPTB) continues to be a challenge in all over World as well as India. First time, this analysis will discover the role of LTA4H gene and may be establishing another candidate that impacts the sensitivity to EPTB in the population of North India. This study will be the first report on LTA4H gene various diagnostic markers, expression of gene may validate as a prognostic factor in (EPTB). The diagnosis (EPTB) poses a special challenge, as it is often missed or misdiagnosed due to its atypical presentations and difficult to isolate M tuberculosis (MTB) due to the small number of organisms present at these sites. Subsequently the outcome of present study will reinforce possible use of LTA4H as biomarkers and the therapeutic utility for (EPTB). This study will be a step to decrease the analytical and therapeutic window to identify another risk factor LTA4H for EPTB. Leukotriene A4 hydroxylase (LTA4H), an enzyme which changes LTA 4 to LTB4, controls the balance amongst the anti-inflammatory lipoxins and pro-inflammatory LTB4, with directly consequences in TB-driven inflammation. In humans and will spawn new ways to protection and enhance the wellbeing status of individuals and population groups. On RT-PCR, Extra Pulmonary Patients had lower expression of LTA4H compared to the controls. Correlation of biomarkers will reveal LTA4H level correlated with age, Gender Smoking, Clinical Parameter Serum Total Protein, BMI Height and TLC, Laboratory Parameter. On ELISA kit and follow as per manufacturer protocol. CEA562Ge 96 Tests Enzyme-linked Immunosorbent Assay Kit For Leukotriene B4 (LTB4) LTB4 Protein level in Extra Pulmonary Patients, (EPTB) (2304.52pg/ml) had lower expression of gene LTB4 compared to the controls (3096.142pg/mls) (P value = 0.0012).

Familial Behcet's disease.

There are very few reports of Behetaet's disease from India. Familial aggregation of Behetaet's disease has been reported with restricted geographical distribution. We report here familial Behcet's disease from India in two brothers aged 30 and 32 years. Both patients had recurrent oral and genital ulcers for approximately five years. They also had arthralgias on and off along with fever. Pathergy test was positive in both cases. Their younger brother and a sister had recurrent oral aphthous ulcers.

Toxicological evaluation of karaya gum; acute and subacute oral toxicity in rats.

Male and female albino rats (Wistar strain) were given single and multiple doses of karaya gum suspended either in peanut oil or mixed with basal diet at different concentrations ranging from 0·5 to 8 g gum/kg body weight. The plant gum did not elicit any overt signs of toxicity or death in both sexes of rats. Daily administration of karaya gum mixed with basal diet at different dose levels (0, 5, 20 and 40 g gum/kg diet) for a period of 90 days showed no adverse effects in male and female rats. The body weight, growth pattern, food and water intake were comparable with those of the normal rats. There were no significant biochemical, or morphological alterations in the vital organs of experimental animals.
