Abstract:-We report a case of secretory carcinoma of the breast in a 62 year old woman. The patient had been aware of right breast mass for 2 years. The tumor enlarged in size and became painful. On examination there was a hard mobile lump measuring about 5X4cms in upper outer quadrant. FNA of breast lump was done FNA smears showed loose clusters of tumor cell having vacuolated cytoplasm with mild to moderate pleomorphism and eccentrically placed nucleus. Subsequently mastectomy was performed. Cytochemistry PAS positive, and immunohistochemistry showed positivity for CEA.
Key words:-Secretory carcinoma Breast, Juvenile breast carcinoma.

Abstract:- Aims: The present study was planned to analysis lung function tests in asymptomatic flour and rice mill workers who are continuously exposed to dust during duty hours. And also planned to investigate the abnormalities in lung function tests, in relation to smoking and non-smoking workers exposed to flour and rice dust Study Design: Cross – sectional study Study Setting: 207 asymptomatic healthy male. Material and Methods: The subject is instructed to take maximal inspiration (to TLC) and he was connected to medspiror through the mouthpiece, after that nose clip is applied and the subject was asked to exhale forcefully into the medspiror as fast as possible. Results: Majority of lung function test parameters showed reduced levels in flour mill workers when compared to rice mill workers. However the difference was not statistically significant. Conclusion: It is concluded that flour dust and rice husk dust causes deterioration of pulmonary functions in subjects working at mills (flour and rice). The findings of this study recognized the role of grain dust (flour and rice) for a longer duration in decline of pulmonary function test among flour mills and rice mills workers. Findings reflect a need for continuing studies of health and safety issues affecting the subjects.
Key-words:- Lung function, flour mill worker, rice mill worker, smoker, non-smoker.

Abstract :-Gurmarin is a 35-residue polypeptide which has been reported to be able to selectively inhibit the neural response to sweet taste sensation in rats. Gurmarin is obtained from Gymnema sylvestre, a commonly used herb in Ayurveda. Ethnomedicinal literatures suggest that, chewing the leaves of the plant causes a loss of sweet taste. Studies of an ethanol leaf extract, GS4, in diabetic rat and rabbit models have reported regeneration of islets of Langerhans, decrease in blood glucose along with increase of serum insulin. However the exact mechanism of action is still unknown. The present study focuses on the identification of the orthologues through the analysis of phylogenetic lineages. The results indicate that there may be three different lineages of the Gurmarin like protein. The first amongst the proteins having knottin like conserved domains, the second amongst the arachnid secreted neurotoxins and the third amongst the sodium channel blockers of arachnid origin. The last two lineages and the conserved residues that are shared lead us to conclude that the Gurmarin might act by competitively inhibiting the ion channel that plays a central role in sweet-taste transduction.
