Thirty-three patients with anterior mediastinal masses underwent percutaneous ultrasonically guided needle biopsy (UGNB), including ultrasonically guided aspiration biopsy (UGAB) in all 33 patients and ultrasonically guided cutting biopsy (UGCB) in 13 patients. Using UGAB alone, the diagnostic rate of anterior mediastinal masses was 52% (17/33); if both the(More)
Chronic duodenal ulcer is diagnosed more frequently in children since recent advances in panendoscopy techniques. From 1976 to 1986, chronic duodenal ulcer was diagnosed in 33 children in this hospital. There was a marked male preponderance (male: female = 4.5:1). Family history for peptic ulcer was positive in 36% of the patients. The important element of(More)
We report the gastrointestinal endoscopic findings in nine patients with Henoch-Schonlein purpura. Eight patients underwent upper gastrointestinal endoscopy, which revealed erosive gastritis in one patient, hemorrhagic-erosive duodenitis in four, and both findings in one. The rectum and the sigmoid colon were examined in six patients. Aphthoid ulcers were(More)
This phase II study was designed to assess the response rate and toxicity of paclitaxel and cisplatin chemotherapy in Chinese patients with untreated advanced non-small-cell lung cancer (NSCLC). Eligibility requirements included histologically confirmed stage IIIb-IV NSCLC, Eastern Cooperative Oncology Group performance status less than 2, no previous(More)
A series of 31 infants and children with acute duodenal ulcer verified by endoscopy was studied over an eight year period. Eighteen (58%) of them were under 2 years of age. The most common symptom was upper gastrointestinal bleeding (n = 27, 87%). Twenty nine patients (94%) had a preceding illness characterised by diarrhoea, upper respiratory tract(More)
With 34 normal, healthy male infants aged 9-17 months, a total of 61 nitrogen (N) balance studies was conducted with N intake between 12 and 180 mg/kg/day. By regression analysis, the crude N maintenance requirements, either with whole egg or cow's milk protein, were estimated to be about the same, 106 and 103 mg/kg/day, respectively. The 97.5% confidence(More)
We raised a specific antiserum against the recombinant M2 subunit protein of ribonucleotide reductase of Leishmania mexicana amazonensis in rabbit. This antiserum was used to study the expression and cellular location of the M2 protein in wildtype as well as hydroxyurea-resistant variants (HuR) of the parasite. The protein increased with increasing dose of(More)
A total of 852 healthy Chinese children from 1 month to 14 years of age were investigated for lactose malabsorption using the breath hydrogen test. A lactose load of 2 g/kg was administered to 528 children and 1 g/kg to another 324 children. The incidence of lactose malabsorption was significantly different among various age groups and between the two(More)
Haemocytes of the giant freshwater prawn, Macrobrachium rosenbergii, were investigated for the induction of apoptosis after phagocytosis of pathogenic yeasts, bacteria and non-pathogenic latex beads in vitro. Isolated haemocytes of M. rosenbergii were cultured at a ratio of 1:50 haemocytes to pathogen with the yeast Debaryomyces hansenii, the bacteria(More)
BACKGROUND Traditional pleurodesis for malignant pleural effusion is performed by large-bore chest tube insertion with the instillation of sclerosing agents after the compressed lung re-expansion and pleural fluid drainage of 100-150 ml/day. This study was carried out to evaluate the possibility of rapid sclerotherapy for malignant pleural effusions by(More)
