Pharmacological properties of a lyophilizate from Galeopsis ladanum on the central nervous system of rodents

The influence of a fraction obtained from Galeopsis ladanum L. on the central nervous system of rodents was examined. The results of these investigations show that the fraction impeded CNS activity. It is practically nontoxic and at a dose of 2000 mg/kg i.p. it does not have a soporific influence on mice. It reduces considerably the spontaneous locomotor activity of mice as well as the locomotor activity of mice stimulated by caffeine, but did not influence the locomotor activity induced by amphetamine. The extract did not exhibit a synergetic effect with barbiturates. The results suggest that the pharmacological activity of the extract resembled the activity of drugs which generally depress the CNS, being on the border between ataractic and sedative drugs.

GREB1L基因突变致后天性单侧肾萎缩一例报道并文献复习

肾发育不良和肾发育不全（RAH）是先天性肾脏与尿路畸形（CAKUT）的主要表现之一,是导致儿童慢性肾脏病的重要原因。遗传因素与发病密切相关,随着全基因检测技术的发展,越来越多与RAH相关的基因突变被报道,GREB1L基因突变已被证实可导致RAH。本研究报道了1例后天性单侧肾萎缩GREB1L基因c.4688A>G杂合突变患儿,并复习相关文献。该患儿基因突变源自母亲,该变异为罕见变异,并且具有不完全外显特性,多种蛋白质危害预测软件预测该突变为有害变异。本文发现了新的GREB1L基因突变位点,可能拓展了与RAH相关的基因突变谱和临床谱。

Allergic bronchopulmonary aspergillosis: Reactivity of IgE and IgG antibodies with antigenic components of Aspergillus fumigatus (IgE/IgG antigen complexes)

Sera of patients with ABPA were tested by XRIE tests incorporating their own serum (self-XRIE) to detect the presence of IgG/IgE antigen complexes to a “reference” Aspergillus fumigatus preparation. Of the 32 sera studied, 29 (90%) had visible precipitin (IgG) peaks, and 27 of these 29 as well as the three apparently precipitin-negative sera, i.e., 30 (94%), showed binding of specific IgE by autoradiography. The two precipitin-positive sera that did not show IgE binding were also skin test negative and RAST negative to this A. fumigatus antigen. Specific IgG as determined in ELISA correlated well with the grading of the XIE precipitin peaks (p < 0.05). There was also a highly significant correlation between specific IgE by RAST and grading the radioactive uptake seen in the autoradiograph (p < 0.001) indicating, for each serum, the presence of IgG antibodies to most of the components to which there was specific IgE. In the self-XRIE tests there was considerable variation of reactivity from serum to serum, in numbers of antigen/antibody peaks observed, in relative peak heights, and in the intensity of the respective staining. By comparing each test to a “reference” pattern developed with the use of an ABPA serum pool, the antigenic components of A. fumigatus were found to be of two main types: (1) antigens that appeared to be poorly precipitating (possibly low-molecular-weight components) but showed strong IgE binding (these were apparently major allergenic components and with one exception proved to be the faster migrating components) and (2) antigens that produced the strongest precipitin reactions with only weak binding of specific IgE and therefore minor allergenic components.

Ehlers-Danlos syndrome type IV caused by Gly400Glu, Gly595Cys and Glyl003Asp substitutions in collagen III: clinical features, biochemical screening, and molecular confirmation

Three patients with Ehlers-Danlos syndrome type IV (EDS IV) and biochemical evidence of structural defects in collagen III were investigated for mutations within the collagen III gene ( COL3A1 ). Single strand conformation polymorphism analysis of α1(III) cDNA indicated the presence of different heterozygous sequence changes in each of the patients. Nucleotide sequencing revealed mutations leading to the substitution of glycine 400 with glutamic acid, glycine 595 with cysteine, and glycine 1003 with aspartic acid. EDS IV is a life-threatening disorder which, as the clinical histories of our patients and their families show, still often escapes diagnosis. Biochemical and molecular studies can clarify the diagnosis and help provide appropriate management and counselling.     

The genes for cytochrome b,ND 4L,ND6 and two tRNAs from the mitochondrial genome of the locust,Locusta migratoria

We have cloned and characterized a 2,778-kb XbaI segment of the mitochondrial genome of the locust, Locusta migratoria. It harbours portions of the ND4 and the ND1 genes, the entire genes for ND6, ND4L and cytochrome b, and the genes for three mitochondrial tRNAs. The genes are arranged in an order which is conserved between orthopteran and dipteran insects. The analysis of the cytochrome b sequence, and its comparison with other systems, supports the current model structure for this polypeptide.
