A preliminary study on the ultrastructure of Middle Permian Acritarch Micrhystridiumfrom western Yunnan has been made using laser scanning confocal microscope (LSCM). Some quite new features about the texture and ultr...
The distribution of unmyelinated nerve fiber in the ovary of amphioxus was found with transmission electron microscopic technique for the first time. The fiber is located under the ovary coat, and in close contact wit...
A considerable progress has been made in studies of chromatin and chromosome ultrastructure during the past fifteen years or so. The discovery of nucleosomes as the basic units of eukaryotic chromatin and chromosomes ...

In the previous note, it has been shown that imbibitional chilling injury is a rather com mon phenomenon occurring during seed rehydration and may cause decline in seedling emergence or loss in crop yield. Its severit...
The Guinier-Preston zone, which has been found in both lunar and terrestrial orthopyroxenes, is a metastable phase of orthopyroxenes with a wollastonite content~25% and a new pyroxene space-group symmetry Pbc 21. It...

With the exception of teleost fishes and some insects, all spermatozoa that have been studied with electron microscopy possess acrosome. The acrosome is essentially vesicles packed with proteinaceous material which pl...
Insect epidermal gland cells were reviewed and classified into 3 classes by Noirot and Quennedey. We studied the structure and physiology of the female sex pheromone glands in Clania variegata Snellen (Lepidoptera, Ps...
