427 patients with varicocele ranging in age from 14 to more than 35 years underwent surgical operation during a 10 year period (1977-1986). 190 (44.5%) were referred for infertility and 365 had left-sided varicoceles (85.5%). No relationship was found between infertility and the grade of varicocele. Clinical features of prostatitis were often present. Semen analyses were performed in 37% o...

We present the molecular karyotype of the megabase chromosomes of Trypanosoma brucei stock 427, clone 221a. This cloned stock is most commonly used in research laboratories in genetic manipulation experiments and in studies of antigenic variation. Using 116 previously characterised chromosome-specific markers, we identify 11 diploid pairs of megabase chromosomes and detect no loss of synteny in...

The human lung adenocarcinoma cell line A-427 is significantly more sensitive to cytotoxic lipid peroxidation products of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) than the human lung adenocarcinoma cell line SK-LU-1, and the glioblastoma cell lines A-172 and U-87 MG. The cytotoxic effect as well as lipid peroxidation were abolished by vitamin E. The differential sensitivities ...

There are some records of early attempts to maintain BF Trypanosoma brucei in vitro [1, 2], but short-term propagation, in the presence of feeder cells (L-cells), was not achieved until 1967 [3]. Continuous propagation was not reported until 1977, when the Lister 427 strain (clone 052 from GAMC) was successfully propagated in RPMI 1640 medium with 25 mM HEPES and 20% heatinactivated FBS, in the...
