Skeletal Muscle Adaptations to Physical Training in Type II (Non-insulin-dependent) Diabetes Mellitus

Seven middle-aged men with manifest type II diabetes mellitus underwent an endurance training programme for 10–15 weeks. The maximal aerobic capacity, as well as the endurance capacity, was improved by 10% (p<0.05). The intramuscular glycogen store increased by more than 80% (p<0.05) from 350 μmol/g dw (dry weight), and the activities of citrate synthase and 3-hydroxy-acyl-CoA dehydrogenase increased by more than 50% (p<0.05) and 30% (p<0.05). The activity of glycogen synthase was decreased by approximately 20% (p<0.05), whereas lactate dehydrogenase remained unchanged. Capillaries/fibre and fibre area increased by more than 50% (p<0.05) and 30% (p<0.05) leaving the area of supply constant. Training did not influence fasting blood lipids and glucose, glycosylated hemoglobin, oral glucose tolerance, and insulin response to an oral glucose load measured 72 hours post-exercise. It is concluded that patients with manifest type II diabetes, as normoglycaemic individuals, adapt to physical training. However, no persistent effect on glucohomeostasis and lipaemia is produced by short-term training in the diabetic patients.     

髁突形态与覆深度关系的研究

目的　探讨髁突形态与不同覆深度的关系。方法　选择正常者、开畸形患者、覆正常的错畸形患者和深覆畸形患者各 5 0人 ,均为 18至 2 6岁成人。应用曲面断层片研究左右两侧的髁突形态 ,分别测量并计算上部髁突高度 /升支高度比 (UCH/RH)和髁突高度 /宽度比 (TCH/CW )。将髁突形态分为四种类型 :直立型 (类A) ,前倾型 (类B) ,后倾型 (类C)和尖型 (类D)。结果　开组的上部髁突高度相对升支高度明显小于其他各组 (P <0 0 0 1)。正常组的髁突形态比较粗壮 ,高度宽度比明显小于其他各组 (P <0 0 0 1)。类A和类B属于正常髁突形态 ,占正常组的 99%。类C和类D属于异常髁突形态 ,且在开组中的比例明显高于正常覆组或深覆组。另外 ,只有开组中显示上部髁突高度两侧不对称 (P <0 0 5 )。结论　开组髁突形态与其他各组相比明显不同。     

A guide to upwardly mobile spermatozoa

Morphological comparison of sperm in raw ejaculates and swim-ups showed that the swim-up process does not simply increase the proportion of 'normal' sperm. Rather, sperm of specific morphologies have characteristic grades of upward motility.     

Virtual real-time digital processing of hemodynamic data

At present, the majority of cardiac catheterization laboratories acquire and store hemo-dynamic data in analog form. To examine the possibility of performing complex analysis of digital data during the catheterization procedure, we examined whether virtual realtime digital (fast Fourier) analysis improves the accuracy of clinical data. We compared digital filtering of fluid manometry during right heart catheterization with 10-Hz and 250-Hz analog filters. Using the simultaneously acquired micromanometry as the “gold standard,” we found that analog filtering is associated with a greater error and time delay than digital filtering. This study demonstrates that digital hemodynamic data analysis performed during cardiac catheterization can improve the quality of data obtained during right heart catheterization, with the results available within seconds. More extensive use of computers in the cardiac catheterization laboratory may be useful for both clinical and research purposes. © 1992 Wiley-Liss, Inc.     

同时测定复方磺胺药各组分的卡尔曼滤波紫外分光光度法

研究了卡尔曼滤波紫外分光光度法测定复方新诺明片和增效联磺片中各组分的实验条件,结果复方新诺明片平均回收率分别为100.4±0.2%(SMZ)和100.4±0.5%(TMP);增效联磺片平均回收率分别为99.5±0.7%(SMZ)、100.8±0.6%(SD)和99.2±0.6%(TMP)。     

Human immunodeficiency virus (HIV)-related chronic relapsing inflammatory demyelinating polyneuropathy with multifocal unusual onion bulbs in sural nerve biopsy

Summary This is obviously the first report on a case with a spontaneous sensu strictu relapsing variant of human immunodeficiency virus (HIV)-related polyneuropathy. Its manifestation preceded LAS. Intrathecal HIV-antibodies developed between the most severe third and fourth episode. Analysis of sural nerve biopsy was consistent with a multifocally accentuated chronic inflammatory demyelination, characterized by unusual onion bulb-like Schwann cell formations with irregular voluminous layers, electron density, aggregation of filaments, multiple indented nuclei, and numerous enclosed collagen pockets. A direct or immune-mediated indirect specific influence on Schwann cell morphology by HIV might be discussed. Virus-like particles and ultrastructural markers of HIV were not detectable.

精子形态变化对体外受精率的影响

目的:通过对ICSI和IVF受精率的统计,比较精子形态中的精子正常形态率、头部畸形率、畸形精子指数(TZI)和精子畸形指数(SDI)对受精结果的影响。方法:用Krger's严格标准法分别计算每组样本的精子正常形态率、头部畸形率、TZI和SDI值,与受精率进行比较。结果:①IVF组和ICSI组的受精率,与精子正常形态率、头部畸形率、TZI、SDI均无相关性。②IVF组和ICSI组中SDI>1.6和SDI<1.6的受精率、优质胚胎率和临床妊娠率差异均无统计学意义(P>0.05)。③IVF组和ICSI组中精子正常形态率≤15%与精子正常形态率>15%的二组间受精率、优质胚胎率和临床妊娠率的差异均无统计学意义(P>0.05)。结论:精子形态在体外受精时对受精率无影响,不能用精子形态来直接评价体外受精的结果。     

中药生精冲剂对精索静脉曲张大鼠的治疗

目的：研究中药生精冲剂对大鼠精索静脉曲张的影响及疗效。方法：从80只SD雄性大鼠中随机抽出20只作为假手术组，余60只均建立精索静脉曲张病理模型后随机均分为模型组、生精冲剂组和克罗米芬组。造模后15d生精冲剂组和克罗米酚组分别给予生精冲剂4g/（kg·d）和克罗米芬20mg/（kg·d）灌胃，模型组和假手术组正常喂食。造模后45d放免法测定血清性激素（FSH、LH和T）及观察各组大鼠睾丸组织结构。结果：生精冲剂组大鼠光镜下睾丸组织结构优于模型组和克罗米芬组；血清FSH、LH生精冲剂组显著低于模型组和克罗米芬组（P〈0.05），而克罗米芬组显著高于其他3组。T在生精冲剂组、克罗米芬组和假手术组之间无显著差异，但均显著高于模型组（P〈0.05）。结论：中药生精冲剂对精索静脉曲张引起的睾丸损害有保护及修复作用，且可能优于克罗米芬。
