Central nervous system impairment is common in diabetic patients, even in the early stages of the
disease, and could be associated with peripheral neuropathy. The aims of this study were to prospectively
investigate central nerve conduction in young adults with type 1 diabetes using pattern-reversal visual
evoked potentials (PRVEP) and to determine how those results were related to clinical risk factors and
the parameters of the peripheral nerve conduction study (NCS). A total of 36 type 1 diabetic patients
(15 males) 5-24 years of age (mean 14.5 ± 4.7) underwent PRVEP and NCS annually for five years.
For comparison, 39 healthy age and sex matched individuals (mean 14.8 ± 5.0) were evaluated as
the control group. The P100 latencies of the PRVEP were prolonged at the study entry in the patients
compared with the controls (p< 0.001). Significant correlations were not found between any of the
parameters of PRVEP and the glycosylated hemoglobin levels; however, the changes in the parameters
of the peripheral NCS were well correlated with metabolic control. The latencies and amplitudes of
the P100 were not related to the majority of the parameters of the NCS. A prolonged PRVEP latency
may be a sign of optic pathway dysfunction, which begins before apparent diabetic retinopathy. Poor
glycemic control proved to be an important risk factor over the 5 years in terms of its relation to
the development of peripheral neural pathway abnormalities. However, once central conduction was
delayed, its changes were poorly related to diabetic control and the attributes of the peripheral nerve
conduction study over the 5-year follow-up.

A controlled study was carried out in 50 patients with perennial bronchial asthma to assess the efficacy and safety of budesonide turbuhaler. Subjects have suffered from cough, wheezing, dyspnea and chest tightness and showed either 15% of reversibility in FEV after bronchodilator inhalation or airway hyperresponsiveness to methacholine(PC20 < or = 25mg/ml.) Patients were randomized to treatment with budesonide turbuhaler or terbutaline turbuhaler for 8 weeks after 2 weeks of run-in period. Budesonide turbuhaler was effective for cough, wheezing, dyspnea and chest tightness. It improved peak expiratory flow rate and FEV1. Budesonide turbuhaler was tolerated well and the laboratory tests showed no abnormality. It is suggested that budesonide turbuhaler is effective and safe in the management of bronchial asthma.

Menetrier's disease is characterized by enlarged gastric folds with foveolar hyperplasia and cystic dilatation of gastric glands. The additional biochemical features of hypoproteinemia, hypochlorhydria, and increased gastric mucus are often encountered. The pathogenesis and etiologic factors have not been clearly defined. In this report, we present two cases of Menetrier's disease in the stomach, one occurring in a 38-year-old male, associated with massive hematemesis, and the other in a 39-year-old male. Grossly, both cases showed marked giant gastric rugal folds resembling cerebral convolutions, sparing the antral portion. Microscopically, the giant gastric rugal folds consisted of the striking foveolar hyperplasia accompanied by an occasional presence of the smooth muscle fibers from the muscularis mucosa. The immunohistochemical stain revealed an intense positive reaction for transforming growth factor-alpha (TGF-alpha) and epidermal growth factor receptor (EGF-R) in the majority of mucous cells throughout the gastric mucosa and parietal cells, but did not reveal for epidermal growth factor (EGF). We suggested that TGF-alpha and EGF-R might be involved in the pathogenesis of Menetrier's disese.

LPS and IFN-r induce nitric oxide synthase in macrophages and the resultant NO causes apoptotic cell death in the activated macrophages. NO production and apoptosis were inhibited by N-monomethyl L-arginine (NMMA), a competitive inhibitor of NO synthase. To study the role of BCL-X proteins, RAW 264.7 cells were transfected with the expression vectors with human bcl-Xl or bcl-Xs cDNAs, respectively. Stable transfectants were selected and confirmed by RT-PCR. NO production in response to LPS and IFN-r caused apoptosis in RAW 264.7 cells and vector transfected control cells within 24 hr. Both NO production and apoptosis were inhibited by N(G)-monomethyl L-arginine (NMMA). In contrast, bcl-Xs transfectant appeared slightly susceptible and bcl-X(L)< transfectant appeared slightly resistant, although NO production was similar to control cells. These results suggest that bcl-X proteins play roles in both positive and negative regulation of apoptosis induced by NO.

BACKGROUND: Early detection of neuropathy may prevent further progression of this complication in the diabetic patients. The purpose of this study was to evaluate the prevalence of early neuropathic complication in patients with newly diagnosed type 1 and type 2 diabetes. METHODS: Nerve conduction studies (median, ulnar, posterior tibial, peroneal, and sural nerves) were performed for 49 type 1 (27 males, mean 14.1+/-7.5 years) and 40 type 2 (27 males, 42.0+/-14.1 years) diabetic patients at onset of diabetes. Children with age at onset under 4 years and adults over 55 years were excluded to eliminate the aging effect and the influence of obstructive arteriosclerosis. Neuropathy was defined as abnormal nerve conduction findings in two or more nerves including the sural nerve. RESULTS: Mean HbA1c level was 12.6+/-3.3% for type 1 and 10.5+/-2.9% for type 2 diabetes. The prevalence of neuropathy was 12.2% for type 1, and 35.0% for type 2 diabetes, respectively. There were significant trends in the prevalence of neuropathy with increasing age (p<0.05). The effect of the mean level of glycosylated hemoglobin on the prevalence of polyneuropathy at onset of diabetes was borderline (p=0.0532). Neither sex of the patients nor the type of diabetes affected the neurophysiologic abnormalities at the diagnosis. CONCLUSIONS: Even in a population with diabetes at the diagnosis, the prevalence of subclinical neuropathy was not low. Neuropathy has been significantly associated with increasing age indicating the possibility of longer duration of undetected diabetes among them, especially in type 2 diabetes.
