From June 2001 to June 2002, in the Hospital 103, 31 patients aged 16-75 were studied. In 100% of them, brochial endoscopy found the contraction of bronchi under direct mechanical stimuli of the end edge of the endoscopy. This mild contraction flashed and self terminated. Out of the outbreak crisis, in 100% of bronchial biopsy samples, inflammation image appeared, and the bronchial structure changed. The main histopathological exhibitions were the infiltration of essinophile white blood, enlarging of bronchi and of the smooth muscle, the hypertrophy of bronchial epithelia and fibrosis under bronchial epithelia

Study was carried out in 162 bronchial cancer patients (83 males, 75 females) in National Institute of Tuberculosis and Lung Diseases from November 1991 to October 1994. Paraneoplastic syndrome account for 51.8% including the symptoms of bone-articular and connective tissues, 43.6% hematology 22.8%, skin 6.8%, endocrino-metabolism 3.1% and kidney 0.6%. Paraneoplastic syndromes of bone-articular connective tissue, include pain manifestations of bones and joints, finger clubbed, symptoms of hematology: anemia, neutrophilia, eosiniphilia and polyplastocytosis; symptoms of skin: hypertrichosis, keratodermia, chloasma cutaneous dystrophy in two feet, vascularmotrice disturbance of inferior limbs; symptoms endocrino-metabolism: hyperuricemia, inaddition, there are some manifestations on kidney and chronical glomerulo-nephritis

This study was conducted to determine the prevalence and characteristics of pathogenic Escherichia (E.) coli strains from diarrheic calves in Vietnam. A total of 345 E. coli isolates obtained from 322 diarrheic calves were subjected to PCR and multiplex PCR for detection of the f5, f41, f17, eae, sta, lt, stx1, and stx2 genes. Of the 345 isolates, 108 (31.3%) carried at least one fimbrial gene. Of these 108 isolates, 50 carried genes for Shiga toxin and one possessed genes for both enterotoxin and Shiga toxin. The eae gene was found in 34 isolates (9.8%), 23 of which also carried stx genes. The Shiga toxin genes were detected in 177 isolates (51.3%) and the number of strains that carried stx1, stx2 and stx1/stx2 were 46, 73 and 58, respectively. Among 177 Shiga toxin-producing E. coli isolates, 89 carried the ehxA gene and 87 possessed the saa gene. Further characterization of the stx subtypes showed that among 104 stx1-positive isolates, 58 were the stx1c variant and 46 were the stx1 variant. Of the 131 stx2-positive strains, 48 were stx2, 48 were stx2c, 11 were stx2d, 17 were stx2g, and seven were stx2c/stx2g subtypes. The serogroups most prevalent among the 345 isolates were O15, O20, O103 and O157.
