Roles of heme oxygenase-1 in the antiproliferative and antiapoptotic effects of nitric oxide on Jurkat T cells.

Nitric oxide (NO) has been shown to exert antiproliferative and antiapoptotic effects on human T cells. Heme oxygenase-1 (HO-1), which degrades heme into biliverdin, free iron (Fe(2+)), and carbon monoxide (CO), has also been known to have antiproliferative and antiapoptotic effects. Recent evidence suggests that HO-1 is an important cellular target of NO; whether HO-1 expression contributes to the antiproliferative and/or antiapoptotic effects mediated by NO remains to be investigated.

Further Observations On The Prevalence Of Ancylostoma Duodenale And Necator Americanus In The Taegu Area.

In order to determine the prevalence of Necator americanus, 182 fecal samples were collected from school children in the Taegu vicinity. These sample were subsequently cultured by the Harada-Mori technique. Necator americanus was differentiated from Ancylostoma duodenale using the bases of morphological characteristics of filariform larvae.

Treatment Of Hookworm Infection With Furfurol.

Furfurol("Furfudol"), a new anthelmintics, was administered to 7 adults and 21 children (6-12 years old) in total amounts of 15.6 mg(base) for 1 to 3 days. It has proven to be effective against hookworms.
