ABSTRACT
OBJECTIVE: To assess the improvement of motor distal latency (MDL), sensory nerve conduction velocity (SCV) of the median nerve and the amplitudes of compound muscle action potential (CMAP) and sensory nerve action potential (SNAP) in patients with idiopathic carpal tunnel syndrome subjected to surgical treatment according to the open carpal tunnel release method and the endoscopic carpal tunnel release. METHODS: Sixty-six hands of sixty-six patients were divided into two groups: the ECTR group and the OCTR group. The patients were evaluated preoperatively, and at 1, 3, 6, and 12 months postoperatively. RESULTS: Although no statistically significant difference of the recovery of MDL and the amplitude of CMAP and SNAP was detected between the two groups at any time point during follow-up, one patient in the ECTR group in whom the operation had been converted to OCTR, showed delay of MDL and decrease in the amplitude of CMAP. CONCLUSIONS: There is a risk of nerve damage in patients undergoing ECTR. Although statistical analysis suggests that nerve conduction improves by about the same degree 12 months after ECTR or OCTR, slightly faster improvement after OCTR cannot be excluded.

Serum eosinophil cationic protein (sECP) levels were measured in 339 patients with childhood asthma, and the clinical courses of these patients were followed for 57 weeks. While considering the history and characteristics of each patient, we examined the correlation between asthma attack frequency and sECP, blood eosinophil count, and serum total IgE (tIgE) to determine their usefulness in predicting asthma attacks. Among patients with no other allergic diseases, sECP levels in patients who had no asthma attacks two weeks before or after the measurement were significantly lower than those of patients who had attacks during the same four-week period. Among patients who had attacks, those patients with no attack for a year after the measurement were also found to have low sECP levels. Similarly, even among patients with asthma attacks and high sECP levels, there were cases where attacks were well controlled using nebulizer treatments with DSCG or BDP. The incident rate of attacks for patients with other allergic diseases and a low sECP was low. Yet, there was no common trend in patients with high sECP levels. Moreover, this study detected a significant correlation between sECP level and blood eosinophil count as well as between sECP level and serum tIgE. The most significant correlation with asthma attack frequency was sECP level. Thus, sECP level seems to reflect the allergy activity level, especially two weeks prior to and after the measurement. For patients without other allergic diseases, asthma attack prediction during the two weeks period after the measurement of sECP also seems possible. Therefore, periodic measurement of sECP level is useful in objectively monitoring the improvement of symptoms and establishing the treatment plan, including treatment with DSCG or BDP.

We examined the effects of purified tannins and related compounds (33 species) on NADH-ubiquinone-1 oxidoreductase activity in four kinds of organism (Paracoccus denitrificans, Bacillus subtilis, Photobacterium phosphoreum, and Thermus thermophilus HB-8) and rat liver mitochondria. In addition to pentagalloylglucose, which was reported as a potent inhibitor of NADH dehydrogenases (NDH), sanguiin H-11, oolonghomobisflavan A, and polymerized procyanidin are potent inhibitors for both types of NDH (NDH-1 and NDH-2). We found that some other tannins contained in tea are also inhibitors of NDH from all organisms.

1. The metabolic fate of midaglizole, 2-[2-(4,5-dihydro-1H-imidazole-2-yl)-1-phenylethyl]pyridine dihydrochloride sesquihydrate, was studied in rats after a single oral dose of 10 mg/kg. 2. After oral administration of 14C-midaglizole to rats, 63% of the dose was excreted in the urine and 41% in the faeces within 72 h. The major radioactive compound in the urine was unchanged midaglizole and accounted for 38.1% of the dose. In the faeces, two major radioactive compounds, M-VII and unchanged midaglizole, were present. These accounted for 17.2 and 14.1% of the dose, respectively. M-VII is a new metabolite, identified as 2-[2-(4,5-dihydro-1H-imidazole-2-yl)-1-(4-hydroxyphenyl)ethyl]pyridine by n.m.r. and mass spectrometry. 3. The biliary excretion of the radioactivity after oral administration of 14C-midaglizole to bile-duct cannulated rats amounted to 53% of the dose. Of the total amount of radioactivity excreted in the bile, 48% was calculated to be subject to enterohepatic recycling. 4. Four biliary metabolites were new metabolites and were identified by n.m.r., mass spectrometry and enzymic hydrolysis. These compounds are 2-[2-(4,5-dihydro-1H-imidazole-2-yl)-1-(4-hydroxyphenyl)-ethyl]pyridine O-glucuronide (M-XI), 2-[2-(4-hydroxyphenyl)-2-(2-pyridyl)]ethyl-2-imidazole O-glucuronide (M-XII),3-(4-hydroxyphenyl)-3-(2-pyridyl)propioimidamide O-glucuronide (M-XIII) and 2-[2-(4,5-dihydro-1H-imidazole-2-yl)-1-(4-hydroxy- 3-methoxyphenyl)ethyl]pyridine O-glucuronide (M-XIV). These glucuronides accounted for 35.4% of the dose. 5. Midaglizole was metabolized in rats mainly via phenyl ring para-hydroxylation followed by glucuronidation, with or without the biotransformation of the imidazoline ring moiety.

The common cause of neonatal facial asymmetry is facial nerve paralysis or "asymmetric crying facies syndrome". In the not uncommon later the lower lip, symmetrical at rest, becomes tilted to the so-called normal side when the patient is smiling or crying, as the congenital hypogenesis of sublabial muscles fail to pull down the lower lip in the opposite side. The electrophysiological differentiation between the two diseases has been performed by orbicularis oculi and oris reflexes with mechanically glabellar and supralabial tapping stimulation, respectively, in addition to needle and/or surface EMG recording. In the facial nerve paralysis of the case 1, R1 and R2 were absent in the orbicularis oculi and oris reflexes. EMG activity was completely lacking over the M. orbicularis oculi and oris innervated by facial nerve. On the contrary, the orbicularis oculi and oris reflexes were normal in the asymmetric crying facial of the case 2. EMG activity was absent only in the sublabial muscles including M. depressor anguli oris and/or M. depressor labii inferioris. Furthermore, needle EMG disclosed no spontaneous activity at rest, which was suggestive of no denervation in the sublabial muscles. It was, however, not possible to determine exactly which muscle the needle was inserted, the M. deprossor anguli oris or the M. depressor labii inferioris. The case 3 might be a variant of asymmetric crying facies with hypogenesis of M. orbicularis oris and/or oculi as well as the sublabial muscle, since the latency was normal but the amplitude was significantly attenuated in the components of orbicularis oculi and oris reflexes.(ABSTRACT TRUNCATED AT 250 WORDS)
