精神分裂症患者的性激素分泌变异   总被引:12,自引:0,他引:12  
为研究精神分裂症患者垂体促性腺激素及外周性激素的功能状态,探讨性激素水平改变与性有关症状和药物治疗的关系,采用放射免疫法测定60例(男40例,女20例)精神分裂症患者的血清促卵泡激素(FSH)、黄体生成素(LH)、催乳素(PRL)、睾丸酮(T)、雌二醇(E2)等激素水平,并与20名(男女各10名)正常人对照。结果显示,试验组中男性LH和女性PRL水平明显低于对照组,女性患者的T与E2水平显著升高。按性有关症状的有无分为两组,两组间性激素水平无显著性差异。药物治疗前后男患者PRL,女患者FSH、PRL、T和E2等激素分泌改变非常显著。氯丙嗪、舒必利可致明显的高PRL血症,但氯氮平无明显影响。提示精神分裂症患者性腺轴存在功能失调。性有关症状与性激素水平改变无关。抗精神病药治疗可导致性激素分泌紊乱。  相似文献

The regional and cellular localisation of gamma-aminobutyric acid(A) (GABA(A)) receptors was investigated in the human basal ganglia using receptor autoradiography and immunohistochemical staining for five GABA(A) receptor subunits (alpha(1), alpha(2), alpha(3), beta(2, 3), and gamma(2)) and other neurochemical markers. The results demonstrated that GABA(A) receptors in the striatum showed considerable subunit heterogeneity in their regional distribution and cellular localisation. High densities of GABA(A) receptors in the striosome compartment contained the alpha(2), alpha(3), beta(2, 3), and gamma(2) subunits, and lower densities of receptors in the matrix compartment contained the alpha(1), alpha(2), alpha(3), beta(2,3), and gamma(2) subunits. Also, six different types of neurons were identified in the striatum on the basis of GABA(A) receptor subunit configuration, cellular and dendritic morphology, and chemical neuroanatomy. Three types of alpha(1) subunit immunoreactive neurons were identified: type 1, the most numerous (60%), were medium-sized aspiny neurons that were immunoreactive for parvalbumin and alpha(1), beta(2,3), and gamma(2) subunits; type 2 (38%) were medium-sized to large aspiny neurons immunoreactive for calretinin and alpha(1), alpha(3), beta(2,3), and gamma(2) subunits; and type 3 (2%) were large sparsely spiny neurons immunoreactive for alpha(1), alpha(3), beta(2,3), and gamma(2) subunits. Type 4 neurons were calbindin-positive and immunoreactive for alpha(2), alpha(3), beta(2,3), and gamma(2) subunits. The remaining neurons were immunoreactive for choline acetyltransferase (ChAT) and alpha(3) subunit (type 5) or were neuropeptide Y-positive with no GABA(A) receptor subunit immunoreactivity (type 6). The globus pallidus contained three types of neurons: types 1 and 2 were large neurons and were immunoreactive for alpha(1), alpha(3), beta(2,3), and gamma(2) subunits and for parvalbumin alone (type 1) or for both parvalbumin and calretinin (type 2); type 3 neurons were medium-sized and immunoreactive for calretinin and alpha(1), beta(2, 3), and gamma(2) subunits. These results show that the subunit composition of GABA(A) receptors displays considerable regional and cellular variation in the human striatum but are more homogeneous in the globus pallidus.  相似文献

Keane JR 《Neurology》2005,65(6):950-952
The author reviewed 34 years of personal experience with inpatients in a large municipal hospital to analyze the seats and causes of involvement of single pairs of cranial nerves. Among 578 cases, the sixth (n = 234) and second (211) nerves predominated, followed by the fourth (48), seventh (30), third (27), and eighth (18) cranial nerves. Trauma (99), infection (94), tumor (92), increased intracranial pressure (85), vascular disease (74), and demyelination (66) were common causes.  相似文献

Hepatocyte growth factor in cerebrospinal fluid in neurologic disease   总被引:2,自引:0,他引:2  
OBJECTIVE: To investigate hepatocyte growth factor (HGF) concentration in cerebrospinal fluid (CSF) in neurologic disease. MATERIALS AND METHODS: We determined CSF concentration of HGF with human-HGF-specific enzyme-linked immunosorbent assays (ELISA) in 121 patients: Alzheimer's disease (AD) (33), amyotrophic lateral sclerosis (ALS) (10), Parkinson's disease (PD) (5), progressive supranuclear palsy (PSP) (3), spinocerebellar degeneration (7), acute disseminating encephalomyelitis (ADEM) (6), human T-lymphotropic virus-1 (HTLV-1)-associated myelopathy (HAM) (6), multiple sclerosis (MS) (7), aseptic meningitis (AM) (12), and peripheral neuropathy and myopathy as control diseases (32). RESULTS: HGF concentrations in CSF were significantly higher with diseases of the central nervous system (CNS) than control diseases and were slightly higher with AD than other neurodegenerative diseases. Values were highest with ADEM but decreased during corticosteroid treatment. We found no relationship between HGF in CSF and CSF cells or protein, immunoglobulin index, or Q albumin. CONCLUSION: It is suggested that high concentrations of HGF in CSF may be partially related to CNS pathology, especially to demyelinating disease.  相似文献

Autonomic impairment in painful neuropathy   总被引:6,自引:0,他引:6  
OBJECTIVES: 1) To determine the degree and distribution and quantitate the severity of autonomic impairment in painful neuropathy (PN). 2) To assess the role of autonomic testing in evaluating PN. METHODS: The authors studied 92 patients with PN (60 women and 32 men, age 56.9 +/- 12.4 years) using: 1) autonomic reflex testing (ART), Quantitative Sudomotor Axon Reflex Test (QSART), cardiac-vagal, head-up tilt, and surface skin temperature; 2) autonomic symptoms questionnaire; 3) nerve conduction (NCS) and laboratory studies; 4) quantitative sensory testing; 5) skin biopsy; and 6) Composite Autonomic Symptoms Score (CASS) scale to grade ART results from 0 (normal) to 10 (autonomic failure). RESULTS: Autonomic involvement in PN had characteristic features. Main symptoms were pain, secretory and skin vasomotor signs, hypertension, and impotence. ART results were abnormal in 86 (93.5%) (CASS < 4), QSART in 67 (72.8%), cardiac-vagal index in 58 (63%), skin temperature in 51 (55.4%), orthostatic hypertension in 39 (42.3%), and family history of PN in 26 (21%) of patients. Group 1 (abnormal NCS) (n = 45) had more severe ART and sensory abnormalities than the Group 2 (normal NCS) (n = 47): 1) CASS 2.0 +/- 0.96 vs 1.55 +/- 0.88 (p < 0.01), cardiac-vagal index (p < 0.02), skin temperature (p < 0.02), hypertension (p < 0.03), cooling (p < 0.002), and vibration (p < 0.0005) thresholds. CONCLUSIONS: Autonomic symptoms in painful neuropathy are predominantly cholinergic and form a unique constellation of features that are distinct from other autonomic neuropathies.  相似文献

Abstract   This review updates and extends earlier Consensus Reports related to current basic and escalating immunomodulatory treatments in multiple sclerosis (MS). The recent literature has been extracted for new evidence from randomized controlled trials, open treatment studies and reported expert opinion, both in original articles and reviews, and evaluates indications and safety issues based on published data. After data extraction from published full length publications and critically weighing the evidence and potential impact of the data, the review has been drafted and circulated within the National MS Societies and the European MS Platform to reach consensus within a very large group of European experts, combining evidence-based criteria and expert opinion where evidence is still incomplete. The review also outlines a few areas of controversy and delineates the need for future research. Appendix    Multiple Sclerosis Therapy Consensus Group (MSTCG) Austria. U. Baumhackl (St. P?lten), T.

Three dimensional analysis of retinal neuropeptides and monoamine-containing amacrine cells were performed on flat-mount preparations of the chick retina by using indirect immunofluorescence method. somatostatin (SOM), neurotensin (NT), leu-enkephalin (ENK), vasoactive intestinal polypeptide (VIP), substance P (SP), corticotropin releasing factor (CRF), avian pancreatic polypeptide (APP), glucagon (GLC), 5-hydroxytryptamine (5HT) and tyrosine hydroxylase (TH) were examined with specific antisera. To localize these substances in the amacrine cells, and to see in which layers their processes arborize, frozen sections were examined. There were four patterns of distribution. (1) Substances with more immunoreactive cells in the central than in the peripheral portions (SOM, NT, VIP, SP, GLC, 5HT), (2) Substances with more immunoreactive cells in the peripheral portion than in the central portion (APP), (3) Substances for which such cells were evenly distributed (TH), and (4) Substances with more immunoreactive cells in the inferior than in the superior portion (CRF). Subtypes were identified among the amacrine cells containing single peptides or monoamine.  相似文献

The subjects were 106 SMIDS with epilepsy. They were classified into four epileptic syndromes: (1) SE-MISF (34.0%), (2) SGE (25.5%), (3) SLRE (20.7%), and (4) epileptic discharge-free patients (EDFP) (19.8%). Clinical electroencephalographic studies elucidated the following result: (1) The seizure disappearance rate was the highest in SLRE (54.5%), and it decreased in the order of EDFP (47.6%), SE-MISF (36.1%), and SGE (11.1%). (2) Status epilepticus was most frequently seen in SGE (62.4%), but it was not so often seen in EDFP (14.3%) or SLRE (22.7%). (3) The age at seizures onset was the lowest in SE-MISF (0.84 years), and it increased in the order of SLRE (1.3), SGE (2.3), and EDFP (6.7). (4) The rate of Ohshima's classification 1 was highest in SE-MISF (61.1%) and lowest in SGE (40.7%). In conclusion, epileptic syndrome and EEG findings are good indicators for predicting the seizure prognosis and some of the clinical features, and the majority of epileptic syndromes could be classified by the very first EEG findings. Since epilepsy in SMIDS is so frequent (70.3%) and intractable (seizure disappearance rate more than 3 years, 36.2%), more attention should be paid to electroencephalography and epileptic seizures in SMIDS.  相似文献
