Fine structure of developed human tongue muscle.
The purpose of this study was to clarify the relationship myofibrils, mitochondoria and other cytoplasmic organella in the developed lingual muscle (vertical, transverse, and longitudinal) by using various microscopic levels: light, scanning electron, and transmission electron. The tongue muscles were examined in seventeen autopsy specimens: eight, 12-32 weeks gestation and ten adults (five mal...
متن کاملCytotoxicity of Subtoxic AgNP in Human Hepatoma Cell Line (HepG2) after Long-Term Exposure
Background: We aimed at evaluating the toxicity effects of low (subtoxic) concentrations of silver nanoparticles (AgNP, 5-10 nm) in human hepatoblastoma (HepG2) cell line after and during a period of about one month. Methods: XTT and MTT assays were used to draw a dose-response curve IC50 (half maximal inhibitory concentration) value of the AgNP on HepG2 cells was calculated to be 2.75-3.0 mg/l...
متن کاملTHE FINE STRUCTURE OF MEISSNER's TOUCH CORPUSCLES OF HUMAN FINGERS
Thin slices of the finger pads of six individuals were fixed in buffered 1 per cent osmic acid, embedded in deaerated, nitrogenated methacrylate, and cut into thin sections for electron microscopic study. Before embedding, the slices were trimmed so as to include several digital tactile corpuscles. Some thin sections were stained in 10 per cent aqueous phosphotungstic acid solution. The princip...
متن کاملAntioxidant Effects of Pinus Eldarica Extracts Against Cisplatin-Induced Cytotoxicity in Human Hepatoma (Hepg2) Cell Line
Background: Cisplatin has cytotoxic effects through free radical generation. Reports indicate that various members of Pinaceae family may have antioxidant properties. In this study we investigated the cytoprotective effects of needle volatile oil and bark extract of Pinus eldarica in hepatoma G2 (HepG2) cell line. Methods: Using the maceration technique, we obtained the ethanolic extract of ...
متن کاملINVESTIGATIVE OPHTHALMOLOGY Fine structure of the human ciliary muscle
The ciliary muscle in human eyes consists of bundles of muscle cells surrounded by flattened connective tissue cells. Each bundle generally contains unmyelinated nerve fibers accompanied by Schwann cells and a few connective tissue components. Some of the nerve fibers contain many vesicles characteristic of nerve endings. The nerve fibers are, in a few cases, in very close apposition to the mus...
