Preliminary study to explore gene-PM2.5 interactive effects on respiratory system in traffic policemen

Physical Processes of processing raw materials to purify furniture can making the hazardous materials such as dust of wood. Workers who are in the area of higher dust levels can overcome complaints of respiratory caused by one of them from the use of masks. Based on a preliminary study 12 out of 16 furniture workers deal with the subjective complaints of respiratory system including coughing, phlegm, and shortness of breath.This purpose study to determine the correlation of the use of masks with a subjective complaints of respiratory system on furniture home industry workers in the Cikeduk Village, Cirebon District. The type of research used is descriptive correlation with retrospectively study design. The population in this study were all workers in 24 furniture home industries in Cikeduk Village totaling 232 workers with sample of 70 people. The sampling technique uses quota sampling. The statistical test used is Chi Square. The results obtained p value of 0,032 and smaller than the value of α = 0,05, this indicates a relationship use of the masks with subjective complaints of respiratory system on furniture home industry workers in the Cikeduk Village, Cirebon District. The need for workers to improve discipline in using masks so that it can help improve the subjective complaints of respiratory system and check their health with routine on health services.

Hormonal Therapies

A preliminary study of human mammary carcinoma on the ultrastructural level is reported for a metastatic, subcutaneous nodule, obtained as a surgical biopsy. The patient's tumor had responded favorably to a series of hormonal therapies, including androgens, estrogens, progestins, and corticoids for recurring nodules over eight years. The pertinent nodule was removed from the region of the gluteal maximus, two weeks following stilbestrol therapy. It was about 1.5 cms in diameter, and was located within the dermis. Pieces from it were fixed immediately in cold fixatives: phosphate buffered osmium tetroxide, glutaraldehyde, and paraformaldehyde. Embedment in each case was in Vestopal W. Contrasting was done with combinations of uranyl acetate and lead hydroxide.

Preliminary Study

A new strain of mice, which had arisen by mutation from a dystrophic mouse colony was designated ‘mdx’, because the genetic defect, which manifests itself in brief periods of muscle destruction followed by episodes of muscle regeneration appears to be X-linked. Further studies of histopathological changes in muscle from ‘mdx’ mice at the light microscopic or electron microscopic levels have been published, but only one preliminary study has been on the tibialis anterior (TA) of ‘mdx’ mice less than four weeks old. Lesions in the ‘mdx’ mice vary between different muscles, and centronucleation of fibers in all muscles studied so far appears to be especially prominent in older mice. Lesions in young ‘mdx’ mice have not been studied extensively, and the results appear to be at variance with one another. The degenerative and regenerative aspects of the lesions in the TA of 23 to 26-day-old ‘mdx’ mice appear to vary quantitatively.
