Histological Changes in Photorejuvenation Induced by 5-Aminolevulinic Acid Photodynamic Therapy in a Photoaged Mouse Model
… be effective for photoaged skins. However, the histological studies of PDT in animal model have rarely been reported. Objectives: I observed the histological changes in photoaged mouse skin specimens and in the specimens after photorejuvenation induced by 5-aminolevulinic acid (ALA)-PDT. …

Detection of muscle damage by B-mode ultrasonography : relationship between echo intensity and histological changes following injection of bupivacaine to rat hind limb muscles
… in echo intensity, and its relationship to histological changes is unexplored. This study tests the hypothesis that infiltration of inflammatory cells in damaged muscle fibres causes an increase in the echo intensity of B-mode ultrasound images. The study is carried out by injecting …

Ultrasonic energy as a cleaning agent and its influence on the respiratory activity and leaf anatomy of Brassica Oleraceae var. Acephala
… energy on the respiratory activity and the histological changes of the tissues involved.

Age, growth, and reproductive biology, of the winter skate, Leucoraja ocellata, in the western Gulf of Maine
… was estimated by measuring morphological and histological changes in the reproductive tract and circulating steroid hormone concentrations. Maturity ogives for males predict that 50% maturity occurs at a total length of 730 mm and at 11 years. For females, maturity ogives predict that 50% …

Evidence That Endogenous Relaxin Promotes Vaginal Growth and Softening in Pregnant Rats
… brings about these effects is to determine the histological changes. Accordingly, the third objective determined vaginal histological changes associated with vaginal growth and softening. Within the stroma relaxin reduced the density of collagen fiber bundles, reduced the length of elastin …

Effects of Daily Oral Injections of Quercetin on Implanted Colon-25 Tumor Growth in Balb-C Mice
… and (3) there was relatively little evidence of histological changes in the quercetin-treated tumor section which would indicate that the action(s) of quercetin is primarily at the subcellular level probably within the nuclei of the tumor cells.

The Roles of Relaxin, Estrogen and Progesterone on Growth and Remodeling of the Cervix and Mammary Glands in the Gilt
We recently described relaxin-induced changes in physical and biochemical properties of the cervix that occur during the last third of the 115-day gestation period in the gilt. Histological changes in the cervix that occur between days 80 and 110 of pregnancy and the effects of relaxin on those …

Characterization of Apoptotic Cells in Equine Proximal Suspensory Desmitis
… dUTP nick end labeling (TUNEL) technique. Histological changes in the abnormal ligaments included mineralization, fibroplasias, neovascularization, collagen degeneration, and significant architecture disruption in 2 ligaments. There was a trend for increased apoptosis in the injured …

Photorejuvenation Induced by 5-Aminolevulinic Acid Photodynamic Therapy in the Patients with Actinic Keratosis: A Histological Analysis
… in premature photoaging. Photodamaged skin is histologically characterized by reduced collagen synthesis, increased collagen destruction, and accumulation of abnormal elastotic material in the dermis. Photodynamic therapy (PDT) is one of many treatment options available for photoaging; it has …

Effects of chronic, sublethal ferric iron exposure on the critical swim speed of rainbow trout (Oncorhynchus mykiss) and critical thermal maximum of cutthroat trout (Oncorhynchus clarkii)
… chronic sublethal ferric iron exposure and changes in Ucrit. The gills were examined for histological changes and fish growth was measured as endpoints. No significant changes in Ucrit growth or gill histology were found in the first experiment, although suggestive trends were noted. The …

Anatomical study of the variation in the branching patterns and histology of the aorta in a South African population
… among South African populations is limited. Histological changes in the aortic wall have been documented and may be due to pathology and physiological processes. Whether these changes are solely due to physiological processes such as haemodynamics or pathology is yet to be determined. The …

An In Vivo Perfusion Apparatus for Studies on Gingival Disease : Assessment by a Perfusion of Nonspecific Proteolytic Enzymes
… of the solution delivered and minimal histological changes due to the presence of the apparatus was demonstrated on these animals. A 1% solution of trypsin was perfused on the experimental area of one animal for one day at the rate of 4.8 ml/day and on another animal for four days at …

Seasonal gonadal changes of adult oviparous oysters in Tomales Bay
… of this study to compare the seasonal gonadal changes which occur in the two species of adult oysters in Tomales Bay with one another, and to compare them with the seasonal gonadal changes which occur in the same species of oysters in other regions. The differences in gonadal changes will be …

A study of lethality and toxic mechanisms of intermittent chlorination to freshwater fish
… part of this study was to investigate the histological changes occurring in the bluegill and rainbow trout that resulted from intermittent chlorination. The data obtained were used to construct an hypothesis concerning the toxic mode of action of chlorine to freshwater fish.

Effects of high intensity focused ultrasound on the intervertebral disc
… or abnormality to the treated animals. Histological changes due to collagen shrinkage in the discs were found, and no damage to the nerve or muscle could be found. The attenuation coefficient in bovine annulus fibrosus was found to be in the range of 1.1 to 1.3 dB cm-1 MHz-1 and the …

The db mouse as a model for steatohepatitis
… administered and lipid peroxidation occurs but histological changes of steatosis and steatohepatitis do not occur. The db/db model is phenotypically distinguished by a large amount of fat storage, diabetes and macrovesicular steatosis that has more lipid peroxidation but no steatohepatitis even …

The Columnar Lined Esophagus: aspects on the assessment of dysplasia and on the relationship with the esophageal submucosal glands
… grades of dysplasia. The interpretation of these histological changes is subjective and suffers from considerable inter-observer variation among pathologists. In study I, we devised and tested two clinically applicable methods for immunohistochemical assessment of p53 and Ki67 as surrogate …
