本文运用微量酶联免疫间接法对27例系统性红斑狼疮(SLE)患者的41份血浆标本进行抗巨细胞病毒(HCMV)IgG和IgM的测定。结果表明抗HCMV-IgG的阳性率在SLE组和正常对照组分别为92.7％和89.5％,几乎无差别;活动期SLE组抗HCMV-IgG的几何平均滴度(GMT)明显高于对照组(P<0.01),而非活动期SLE组抗HCMV-IgG水平与对照组差别不显著(P>0.05)。抗HCMV-IgM的阳性率在活动期SLE组为33.3％,非活动期SLE组为40.0％,均显著高于对照组(10.53％);但各组在抗HCMV-IgM的滴度上差异均无显著性。上述结果表明,SLE和HCMV感染有一定程度的相关性,本文从某些方面论述了产生这种相关性的可能原因以及这种相关性对SLE的发生发展可能产生的影响

Photoperiodicity and the function of the hypophysis and the adrenal cortex

Summary The ACTH content of the hypophysis of rats rises from a minimum in the morning to a maximum in the evening hours. These fluctuations are associated with the diurnal rhythm of light and darkness, and are abolished under conditions of continual light or darkness for 30 days. Rhythmic fluctuations of the ascorbic acid content of the adrenals are also found, with maximum values in the evening, and these are likewise abolished by maintenance under conditions of constant illumination.Presented by Active Member AMN SSSR V.

Characteristics of the topographic interrelation of the head of the pancreas and the duodenum and pathology of the organs of the pancreatoduodenal area

Seventy pancreatoduodenal complexes of 55 patients with chronic pancreatitis and tumours of this zone and 15 patients died from other diseases are studies histotopographically . The pieces of the pancreatic head tissue in the medial wall of the duodenum were found in 12 cases of the first group and in 4 control cases. The pancreatic tissue consisted either of all elements of this organ or cystically dilated ducts and seemed to infiltrate different layers of the duodenum wall. Three variants of the pancreatic head structure are suggested on the basis of anatomo-topographical interrelationships of the pancreatic head and duodenum. In 12 out of 14 cases chronic pancreatitis and carcinoma of organs of this zone were combined with the variants of the pancreatic head structure, in 2 cases there was a true heterotopy . Pathogenetic significance of these variants for the development of chronic pancreatitis is discussed.     

指背腱膜滑动与近侧指间关节屈曲关系及临床意义

Cycloversion and cyclovergence: the effects of the area and position of the visual display

Rotation of a display in the frontal plane evokes a conjugate nystagmic rotation of the eyes (cycloversion) about the visual axes, with slow phases in the direction of stimulus motion — a response known as torsional optokinetic nystagmus (TOKN). Antiphase rotation of large dichoptic displays evokes a disconjugate rotation of the eyes about the visual axes, a response known as cyclovergence. Using the scleral-coil technique for monitoring eye movements we recorded TOKN evoked by black-and-white sectored displays rotating about the visual axis at an angular velocity of 30°/s. The display was confined to central areas with diameters ranging from 5° to full field or with the central 5° to 75° occluded. A 5° central display evoked TOKN with 40% of the gain for the full-field display and gain increased as a function of the size of the display. The gain of TOKN decreased with increasing size of a central occluder. These characteristics of TOKN are similar to those of horizontal OKN. Cyclovergence was virtually absent with a 5° display but was immune to occlusion of the central 40°. Cyclovergence therefore differs from cycloversion in showing no preference for centrally placed stimuli. These effects are free from the influence of stationary edges, since these were concentric with the stimulus motion. The effects are also free from the influence of voluntary pursuit, since humans do not normally have voluntary control over torsional eye movements.     

Organization and distribution of the upper and lower esophageal motoneurons in the medulla and the spinal cord of the rat

The upper cervical esophagus is exerted on swallowing and peristalsis by somatic and visceral motoneurons, whereas the lower esophagus is exerted on only peristalsis by visceral motoneurons. We examined the origin of the esophageal motoneurons and whether there were any differences between the distributions of the upper and the lower esophageal motoneurons in the medulla and the spinal cord using cholera toxin subunit b (CTb) as the retrograde tracer. Following injection of CTb into the cervical esophagus resulted in heavy labeling of the neurons in the nucleus ambiguus including the compact (AmC), semicompact (AmS) and loose (AmL) formations, and the medial column of lamina IX at the C1-C5 levels of the cervical spinal cord corresponding to the spinal accessory nucleus. A few labeled neurons were found in the inferior salivatory nucleus, the rostral division of the dorsal motor nucleus of the vagus (DMX), the accessory facial nucleus and the lateral column of lamina IX at the C2 and C3 levels. All these labeled neurons showed ChAT immunoreactivity. When CTb was injected into the cut end of the unilateral recurrent laryngeal nerve, many labeled neurons were found in the ipsilateral AmC, the AmL, and the bilateral medial column at the C1 and C2 levels. Following injection of CTb into the subdiaphragmatic esophagus resulted in heavy labeling of the neurons only in the AmC and the DMX. When CTb was injected into the sternomastoid muscle, many labeled neurons were found in the medullary reticular formation, the facial nucleus, the medial column at the C1-C3, C5 and C6 levels, and the lateral column at the C2, C3, C5 and C6 levels. Injections of a Fluoro-Gold into the cervical esophagus and a CTb into the sternomastoid muscle or the subdiaphragmatic esophagus in the same animal showed many double labeled neurons in the medial column of the accessory nucleus at the C1 and C2 levels, but no double labeled neurons in the AmC. These results indicated that the upper cervical esophagus is innervated by the visceral medullary vagal motoneurons as well as the somatic spinal accessory motoneurons. The lower esophagus is innervated only by the visceral medullary vagal motoneurons.
