Phenoxyethanol is used at concentrations below 1% as a preservative in cosmetic products and fixative perfumes. Some people have reported adverse responses to phenoxyethanol on their skin. suggest that the test subjects' negative reactions are result of allergies. Nevertheless, there claims it's simply skin irritant has varying degrees effect various people. In 2012, ANSM (French National Agenc...

bstract A simple routine microwave antigen retrieval procedure allows the sensitive detection of incorporated BrdU in pulse labeled cells. Of the two fixatives tested, Carnoy’s offers superior nuclear morphology, but with a sacrifice of immunostaining intensity. For investigations where animals are sacrificed within several hours after pulse labeling, Carnoy‘s fixative may prove adequate as a g...

Background: Fixation of biopsy specimens is a critical step before processing and staining them for histological tissue examination. Formalin considered the gold standard fixative solution its attributes. However, it has concerning side effects, such as carcinogenic potential irritational properties. Owing to various harmful safer natural substitute should be explored. In this study, we compare...

Calcium-binding sites were detected in the electrocyte of Electrophorus electricus (L.) using the Oschman & Wall technique, in which CaCl2 was added to the fixative and washing solutions. Deposits were seen scattered along the plasma membrane of the electrocyte, inside mitochondria, associated with the post-synaptic membrane and the membrane of synaptic vesicles.

A chemosurgical method for the removal of accessible neoplasms under complete microscopic control has been developed for use in human cancer. This is to be described elsewhere in the near future (2). The object of the present paper is to describe some of the animal research which led to the development of this method and which has been withheld from publication until the treatment had been appl...

40 min after a single injection of 50 microCi of tritiated thymidine a 3 mm punch of DBA-1 mouse skin contains about 1000 dpm. This value remains constant for at least 48 hr after injection. 50 hair follicles contain about 40 dpm, and from these values the activity calculated to reside in the basal layer of a 3 mm punch of skin is 760 dpm. These values also remain constant with time after injec...

INTRODUCTION All good tissue specimen preparations require complete fixation. The process of tissue handling and processing from patient to paraffin block is too frequently invisible to the pathologists. Many times due to certain emergencies or unavailability of a proper fixative, tissues are kept in different carrying media such as normal saline (NS) or local anesthetic till the availability o...
