This study describes histology and ultrastructure of uterus in the African giant rat during oestrous cycle. Endometrial histology displayed glandular mucosa consisting of lamina epithelialis and lamina propria mucosae. Its epithelium varied between simple and pseudostratified columnar. The myometrium consisted of inner circular and outer longitudinal smooth muscles with medium sized arteries an...

BACKGROUND Iris plays important roles in ocular physiology and disease pathogenesis. Currently it is technically challenging to noninvasively examine the human iris ultrastructure in vivo. The purpose of the current study is to reveal human iris ultrastructure in patients with synechiae by using noninvasive in vivo laser scanning confocal microscopy (LSCM). METHODS The ultrastructure of iris ...

The aim of this study is to the effect dark deprivation on ultrastructure epidermal keratinocytes. Electron microscopic evaluation status keratinocytes epidermis skin white outbred rats with deprivation. For morphometric production capacity counting number granules per 100 μm2. Using application program ImageScopeM determines average and equivalent indicators lamellar bodies (μm), as well their...

The present study aims to investigate if Cimicifuga racemosa (L.) Nutt extract (CIMI) reduces deleterious effects of dexamethasone (DEXA) in ovaries cultured vitro. Mouse were collected and DMEM+ only or supplemented with 5 ng/mL CIMI, 4 DEXA, both CIMI DEXA. at 37.5°C 5% CO2 for 6 days. Ovarian morphology, follicular ultrastructure, the levels mRNA Bax, Bcl-2, Caspase-3 evaluated. results show...

The aim of the study was to assess effects therapeutic ultrasound (US) on oxidative stress (OS)-induced changes in cultured human chondrocytes (HCH). For this, monolayer HCH were randomized three groups: a control group (CG), exposed OS (OS group), and US (US-OS group). exposure performed prior induction by hydrogen peroxide. Transmission electron microscopy (TEM) used ultrastructure. inflammat...
