Acta Anatomica Sinica 1957;0(04):-
Cardiac muscles of mouse embryos, newborn and suckling mice were used for histological and histochemical studies. This paper presents the observations on the morphogenesis and ultrastructure of cardiac myocytes under electron microscope and on their reactions of nucleic acids (DNA and RNA), glycogen, lipids, succinodehydrogenase (SDH), alkaline and acid phosphatases (AKP and AcP), glucose-6-phosphatase (G-6-Pase) and adenosine triphosphatase (ATPase) under light microscope.The heart of mouse embryo before 12-day, contained numerous polygonal or star-shaped myoblasts which had not yet acquired myofibrils but a few myofilaments. As the myoblast developed, the number of myofilaments increased in number and formed myofibrils, then the cells became myocytes. By the end of embryonic period, all the special elements of myocyte were basically constituted. The myocytes of embryos were rich in RNA granules, and their DNA was deeply stained. Flourishing mitosis appeared only in the early embryonic phase. RNA of adult myocytes was much less than that of embryos. From the early phase of embryos myocytes were full of glycogen but short of lipid droplets. From the day it was born, glycogen decreased apparently but lipid droplets increased rapidly.The reaction of SDH steadily increased in intensity from its early phase to late one. After birth it became more intensive. G-6-pase first appeared in the myocytes of 14 day's embryos. In the fetal period it showed moderate positive reaction, but in the myocytes of suckling muose it appeared negative. The enzyme showed positive reaction again at the age of 2 weeks. The ATPase reaction was found to be weak in the fetal specimens, only appeared in the endothelium of the capillaries. After birth it gradually became intensive and from the 2nd week positive reaction was obvious in adult, it was very vigorous.The above observations showed that the embryonic development and differentiation were gradually completed. Histological and histochemical features of each developmental period showed their individualities, which confirmed the evidence that the cardiac muscle developed not only successively but also by stages, and approached adult's level at 2nd week end after birth.

OBJECTIVE To investigate the prevalence of extended-spectrum ?-lactamases (ESBLs) and antibiotic resistance in Klebsiella pneumoniae isolates.METHODS ESBLs-producers were detected by CLSI phenotypic confirmatory test and susceptibilities were tested by agar dilution method.RESULTS 41.1% Of isolates were ESBLs producers in those isolates. ESBLs producers were highly resistant to piperacillin,cefazolin,cefuroxime,fluoroquinolones,chloramphenicol,SMZ-TMP and amikacin. The resistant rate to piperacillin-tazobactam,and ceftazidime was 26.3% and 34.2%. None was resistant to imipenem and meropenem in ESBLs producers. Except for carbapenems,the resistant rate to other antimicrobial agents was significantly higher in ESBLs producers than non ESBLs producers.CONCLUSIONS With resistance to most of antimicrobial agents,ESBLs-producers are highly prevalent in K. pneumoniae isolates,more attention should be paid to monitor these strains.

Serum concentrations of interleukin-6 (IL-6), soluble IL-6 receptor (sIL-6R) were determined in patients with Graves′ ophthalmopathy (GO), Graves′disease without GO (NGO) and controls. Patients with GO treated by corciosteroids were assessed by the clinical activity score (CAS). The results suggested that serum levels of both IL-6, sIL-6R and CAS could reflect the activity of GO and predict the outcome of corcicosteroid therapy.
