Effects of partial hepatectomy on the immune responses in mice.

Experiments were performed to investigate the immune responses occurring as a result of partial hepatectomy (HEP) in mice. On Day 12 mice subjected to HEP showed a twofold rise in serum levels of IgG when compared with sham-operated (ShO) controls. The effects of HEP on specific antibody production following a single immunization with sheep red blood cells (SRBCs) were investigated.

In vivo effect of staphylococcal enterotoxin A on peripheral blood lymphocytes.

Staphylococcal enterotoxin A (SEA) administration to monkeys produced an initial lymphocytic leukopenia lasting approximately 24 h. Lymphocytes isolated from blood circulation (PBL) during this stage had normal or decreased [3H]thymidine incorporating activity. After 48 h, however, a significant increase (five- to sixfold) in [3H]thymidine incorporating activity into PBL was apparent.

Leptospirosis in Israel: a report of 14 cases caused by icterohaemorrhagiae serogroup (1968-82).

Fourteen cases of leptospirosis due to the Leptospira interrogans serogroup Icterohaemorrhagiae (Weil's disease) were serologically confirmed in the last 15 years. In two cases, Icterohaemorrhagiae was also isolated from the patients' blood. Both positive cultures were obtained in Korthof's medium by indirect passage through brain-heart infusion medium.

Leptospirosis in man, Israel, 1970-1979.

In 1970-1979, the incidence of human leptospirosis in Israel was 0.7 per 100,000 population. The majority of the cases (62%) occurred in northeastern Israel (Upper Galilee).

Leptospirosis among dairy workers in the valley of Jezreel: first recorded isolation of Leptospira hardjo in Israel.

Five cases of leptospirosis among dairy farmers in the Valley of Jezreel are described. The disease was caused by leptospirae of serotype hardjo and available epidemiological evidence suggested infection due to contact with cows. This is the first time that Leptospira hardjo has been isolated and identified in Israel.
