Dengue virus causes dengue fever, a mild febrile illness, and at times dengue hemorrhagic fever (DHF), a severe illness the pathogenesis of which is not fully understood. Given the crucial roles played by interleukin-8 (IL-8) as a chemoattractant cytokine and in inflammatory processes, levels of circulating IL-8 in the sera and IL-8 mRNA in the peripheral(More)
The objective was to examine changes in trace elements due to thyroid cancer in humans. Serum levels and tissue contents of trace elements (Zn, Cu, Mn, Mg, Fe and Se) were measured in 43 patients with thyroid cancer before and 4 days after surgery were compared to normal values. The serum levels of zinc in cancer patients were lower than those of normal(More)
Forty-two cases of abdominal tuberculosis seen between June 1984 and June 1988 at Amiri Hospital in Kuwait were reviewed retrospectively. The clinical diagnosis was correct in only 35%. Nine patients presented as an emergency, but in none was a diagnosis of tuberculosis considered. Abdominal pain and tenderness were the commonest clinical findings; "doughy(More)
OBJECTIVE To determine the relative importance of clinical presentation, laboratory studies, and ultrasonography in the diagnosis of acute scrotum, and to suggest an effective method of management. SUBJECTS AND METHODS Forty patients who were hospitalized between January 2002 and December 2002 for acute scrotum were studied with respect to history,(More)
BACKGROUND Breast cancer comprises 22% of all cancers occurring in females but only 2% of cases occur in women aged 35 years and less. The presentation, behaviour and prognosis of breast cancer in such women, when compared with older women, are unclear and conflicting results have been reported. This study has audited clinical and pathological features in(More)
Repeated administration of carbon tetrachloride (CCl4) induces liver cirrhosis, possibly because it involves the production of free radicals. In order to evaluate the effect of free radical scavengers such as superoxide dismutase (SOD) and allopurinol in the pathogenesis of liver cirrhosis, rats were subjected to repeated CCl4 administration with and(More)
OBJECTIVES An understanding of the tissue and organ level of antioxidant enzymes that scavenge reactive oxygen species may provide an indication of their susceptibility to free radical-related cytotoxic damage. A direct association between testicular production of excessive reactive oxygen species and male infertility has been noted. We measured the(More)
Different doses of thioacetamide (0.05, 0.1 and 0.15%) were used to induce liver cirrhosis in Wistar rats. Thioacetamide at 0.5% caused cirrhosis by the twelfth week of treatment. A severe bile duct proliferation and cholangiocarcinoma was seen at longer intervals. Animals treated with higher doses (0.1 and 0.15%) of thioacetamide developed more severe(More)
Serum antioxidant (urate, alpha-tocopherol) activity and cholesterol concentration in 142 patients of Indian and Arab (Kuwaitis and other Arabs) origin with different types of cancer (breast, colon, stomach, thyroid, oral, rectal, pancreatic, and renal) were compared to 100 age- and sex-matched control subjects. Values were expressed as medians(More)
