Abstract

Cigarette smoke is proved to cause various disturbances on respiratory tract. Clove cigarette is far more dangerous than common (“white”) cigarette, since the tar, nicotine, and carbon monoxyde content is significantly higher. In Indonesia, 88% smokers consume clove cigarette. The clove cigarette effect to the respiratory tract have never been studied. Aim of this  research is to study histopathological changes of respiratory tract in Sprague-Dawley white rats after smoke cigarette exposure. The study was performed using 20 white rats starting September 2005 until May 2006. Necropsy was done after final day of smoke exposure, then histopathological slides of the respiratory tract were processed and stained under light microscope and videomicrometer. Observed parameters were height and number of ciliated epithelia and goblet cells, also number of pneumocytes types I, II, and macrophages, and interstitial lung tissue reactions. The latest parameters were observed with semi-thin sections of resin embedded lung stained with Toluidine Blue. Result showed considerable histopathological changes on respiratory tract. The amount of epithelial cells on the group exposed to clove cigarette smoke were significantly higher than control group (P<0.05) on sinus, bronchi, and bronchioli area, while no significant difference were found on trachea (P>0.05). Number of goblet cells in exposed group was also higher (P>0.05). The epithelial height in exposed group was higher compared to control, but no statistical differences were found between male and female rats. The interstitial  pneumonia score was statistically different (P<0.05) between the two groups. The amount of pneumocytes type II was higher than types I within the exposure group. Based on all mentioned above, we suggest that clove cigarette smoke exposure causes pathological disorders in rat respiratory tract.

Abstract

The nematode, Ascaridia galli, caused pathological changes in the gut, while the larval development takes place in the intestine epithelium. The aim of this research was to examine the effect of excretory/secretory product released by L3 of A. galli to prevent intestine destructions based on villous compact in duodenum, jejunum, and ileum of laying hens. Excretory/secretory was prepared from metabolic of L3 released in culture médium in flasks containingrosswell park memorial institute (RPMI) 1640 media, pH 6.8, without phenol red. Excretory/secretory product was concentrated with vivaspin 30.000 MWCO. The chickens vaccinated with 80 >g protein excretory/secretory in crudemixed with Fruend Adjuvant Complete and repeated three times with dose of each 60 >g mixed with Freund Adjuvant Incomplete with an interval of one week intra muscularly. The chickens were challenged with 1000 infective larvae A. galli one week later. After two weeks the chickens were operated. Villous compact in duodenum, jejunum, and ileum of laying hens were analyzed. The result showed that immunization was able to sustained significantly intestinevillus compact, particularly in duodenum. This research concluded that the excretory/secretory product could protect villus in duodenum against parasitic diseases caused by A. galli.
