Empty Sella and Headache 总被引:2,自引:0,他引:2
Teresa Catarci Fabrizio Fiacco Luigi Bozzao Manuela Pati Alice Valeria Magiar Rosanna Cerbo 《Headache》1994,34(10):583-586
SYNOPSIS
Empty sella is an anatomical condition caused by herniation of the subarachnoid space into the pituitary fossa through an incompetent seller diaphragm. Headache seems to be one of the most frequently reported symptoms. We studied 13 headache patients (12 females, 1 male) presenting with primary empty sella (PES) on CT scan. The characteristics of the headache were analyzed and plasma levels of pituitary hormones or cortisol assessed. We confirmed the nonspecific nature of the headache in PES even though the majority of our patients complained of daily headache, mostly localized anteriorly. Hormone plasma levels were within normal range in all the patients assessed. However, four patients reported earlier endocrine disorders and more than half of the patients presented with obesity.
In our opinion, PES should be suspected in middle-aged overweight women with daily headache even in the absence of endocrine symptomatology. 相似文献

Successful cryopreservation of human bone marrow does not require a controlled-rate freezer 总被引:3,自引:0,他引:3
We studied CFU-GM recovery from bone marrow samples frozen either in a machine for controlled-rate freezing or in a -70 degrees C freezer. We found no statistically significant difference between the two methods. Cooling-curve investigations also demonstrated that it was possible to obtain satisfactory cooling rates simply by manipulation of the shape and volume of the marrow and its container. Five patients received a total of six successful autografts for which their marrow cells were frozen without controlled-rate freezing. Thus it is not necessary to use a sophisticated machine in order to obtain satisfactory cryopreservation of human marrow stem cells. 相似文献

Detection of carriers of Beta hemolytic streptococci and serogrouping of the strains isolated from throat of School Children helps in the epidemiological serosurveillance of the disease. With this in view the carriers among otherwise healthy school children in and around Buria, a small town in western Orissa, have been detected and the Streptococci isolated are grouped and typed. 相似文献

One hundred ninety (190) serum samples and 52 control samples consisting of high risk individuals were screened for anti HCV antibody by 3rd generation ELISA test. The prevalence rate was found to be 1.57% in total but it was 2.12% in healthy voluntary blood donors. All were males between the age group of 21 to 40 years. All the control samples were found to be seronegative for anti HCV ab. 相似文献

Gene conversion is a likely cause of mutation in PKD1 总被引:3,自引:0,他引:3
Watnick TJ; Gandolph MA; Weber H; Neumann HP; Germino GG 《Human molecular genetics》1998,7(8):1239-1243
Approximately 70% of the gene responsible for the most common form of
autosomal dominant polycystic kidney disease ( PKD1 ) is replicated in
several highly homologous copies located more proximally on chromosome 16.
We recently have described a novel technique for mutation detection in the
duplicated region of PKD1 that circumvents the difficulties posed by these
homologs. We have used this method to identify two patients with a nearly
identical cluster of base pair substitutions in exon 23. Since pseudogenes
are known to be reservoirs for mutation via gene conversion events for a
number of other diseases, we decided to test whether these sequence
differences in PKD1 could have arisen as a result of this mechanism. Using
changes in restriction digest patterns, we were able to show that these
sequence substitutions are also present in N23HA, a rodent-human somatic
cell hybrid that contains only the PKD1 homologs. Moreover, these changes
were also detected in total DNA from several affected and unaffected
individuals that did not harbor this mutation in their PKD1 gene copy. This
is the first example of gene conversion in PKD1 , and our findings
highlight the importance of using gene-specific reagents in defining PKD1
mutations.

A tannase producing bacterial strain KBR 6 has been isolated from lateritic soil and identified as Bacillus licheniformis. It is capable of producing tannase in the medium containing only tannic acid. The rapid degradation of tannic acid and production of extracellular tannase was observed in three different media containing tannic acid (M1), tannic acid + basal salt (M2) and tannic acid + basal salt + glucose (M3). Maximum enzyme production and growth of the organism was obtained at 18-21 h and 30-36 h, respectively. The increased order of enzyme production in relation to different media is as per the following sequence, M3 > M2 > M1. The maximum growth and enzyme production was observed at pH 5.0. The pH and temperature optima of the enzyme activity were found to be at 5.75 and 60 degrees C respectively. Paper chromatographic analysis indicates that gallic acid is the enzymatic degradative product of tannic acid. 相似文献
