[Pregnancy in obese women (A'uthor's transl)].

Between 1969 and 1971 4,749 antenatal patients were observed. Compared to the tables for ideal weights of the Metropolitan Life Insurance Company Statistical Bureau, 26.76 percent of the patients were above ideal weight and 11.35 percent of the patients were obese. It was found that complications and illnesses during the pregnancy increased progressively with weight groups above the ideal weight. Hypertension was five times as frequent in obese women than normal, edema and proteinuria were common. Pre-eclampsia was more common in the obese. Varicosities occurred much more often in the maternity cases above normal weight and with obesity.

Expression of Bacillus subtilis levanase gene in Lactobacillus plantarum and Lactobacillus casei.

Two Lactobacillus-Escherichia coli shuttle vectors, harbouring the levanase gene from Bacillus subtilis under the control of its own promoter (pLPEW1) or behind the E. coli tac promoter (pESIEW2), were constructed. Lactobacillus plantarum showed the same growth characteristics on selective plates and in liquid media containing inulin, after transformation with either pLPEW1 or pESIEW2. L. plantarum transformed with pLPEW1 could be selected on inulin plates, indicating that levanase expression can be used as a food-grade selection system for Lactobacillus. Lactobacillus casei grew faster in inulin-containing medium than L. plantarum after transformation with pESIEW2, but did not grow when harbouring pLPEW1. Inulin-degrading activities of 90 mU/ml were found in culture medium of L. plantarum containing pLPEW1 or pESIEW2, and of 500 mU/ml in medium of L. casei (pESIEW2). Addition of 1 mM isopropyl beta-D-thiogalactoside to the culture medium had no effect on growth and levanase expression in L. plantarum (pESIEW2) and L. casei (pESIEW2) strains. Levanase produced by L. casei (pESIEW2) has a size of 75 kDa and 72 kDa, corresponding to that of unprocessed and mature B. subtilis levanase, respectively, suggesting that the protein produced is recognized and processed by a signal peptidase.
