    Notes: Abstract As part of a large, prospective study we investigated the prevalenceHelicobacter pylori serum antibodies in children with recurrent abdominal pain (RAP). All patients suffered from recurrent bouts of abdominal pain for at least 6 months and ranged in age from 6 to 12 years.H. pylori antibodies were detected using an enzyme-linked immunosorbent assay. The prevalence ofH. pylori antibodies in the RAP group was compared to that of a control group which consisted predominantly of pre-operative children. None of the control group suffered or had suffered from RAP. Antibodies toH. pylori were found in 7 of 82 (8.5%) RAP patients and in 2 of 39 (5.1%) control children. The latter difference is not significant and suggests that RAP is only rarely caused in children byH. pylori infection.

    Einbau von15N-Glyzin in VLDL und LDL: In-vivo-Synthese von Apolipoprotein B beim Menschen postabsorptiv und im Fastenzustand (1989)

    Notes: Summary In vivo synthesis of apolipoprotein B 100 (ApoB) was recently determined in man using stable isotopes. With this procedure we analyzed (1) the effect of fasting on synthesis of ApoB from very low density lipoprotein (VLDL) and (2) tracer enrichment in low density lipoprotein (LDL). After a 36-hour fasting period and in the post-absorptive state 4 healthy subjects were given a priming dose (8.7 µmol/kg) of15N glycine followed by a constant infusion (10 µmol/kg/h for 8 h) to achieve 5% tracer enrichment in the plasma pool of glycine. The K-values, i.e. fractional synthetic rates/hr of ApoB from VLDL were 0.53±0.26 vs. 0.43±0.16 (p〉0.05). Tracer enrichment in ApoB from LDL at the end of the infusions was 0.19% vs. 1.46% in ApoB from VLDL. The results indicate that (1) in young healthy postabsorptive individuals about 40% of ApoB from VLDL in plasma is synthesized per hour, (2) fasting does not materially affect fractional ApoB synthesis and (3) at 5%15N enrichment in plasma glycine, tracer enrichment in ApoB from LDL is at the lower limit of detection for the procedure employed.

    Notes: Abstract Background: Primary gastric non-Hodgkin's lymphomas possibly develop in response to local infection by Helicobacter pylori (H. pylori). We investigated the presence of H. pylori and non–H. pylori flora histologically in small- and large-cell primary gastric lymphoma using a specific staining method. Materials and methods: Specimens of 52 cases of primary gastric lymphoma(17 small cell, 35 large cell) were stained with modified Giemsa (MG) and immunohistochemically using a polyclonal antibody against H. pylori (IHC). Results: Thirty-two cases (61.5%) (small cell 76% versus large cell 53%,P 〉 0.05) showed immunoreactivity for H. pylori in the mucosa surrounding the tumor. Remarkable, there waslocalization of H. pylori in the neck of the gastric glands in 3 cases.Non– H. pylori flora was seen in 35 cases (76.3%) (small cell53% versus large cell 74%,P 〉 0.05). In 20cases, this non– H. pylori flora was mixed with H. pylori. Five cases showed no bacterial flora at all. Conclusions: (1)Using immunohistochemistry, the prevalence of gastriclymphoma cases with H. pylori (61.5%) approximates that of H. pylori in the normal population. (2) No statistical difference was found between the occurrence of H. pylori and non–H. pyloribacterial flora in small- versus large-cell lymphoma. (3) Our results suggest that H. pylori may not be the only etiologic factor in primary gastric lymphoma.
