The effect of osmolarity on mouse parthenogenesis
Development, 1974ABSTRACTEggs from (C57BI × A2G)F1 mice were activated by treatment with hyaluronidase, which removed the follicle cells, and cultured in vitro. Observations were made 6–8 h after hyaluronidase treatment to determine the frequency of activation and the types of parthenogenones induced.

Relationship between Osmolality and Osmolarity
Journal of Pharmaceutical Sciences, 1978Since the compendia require the osmolarity of certain parenterals to be labeled and since experimentally only the osmolality can be measured, it is necessary to obtain the relationship between these two quantities. This relationship was determined by considering fundamental physical-chemical definitions.

Tear Osmolarity in Premature Infants
Journal of Pediatric Ophthalmology & Strabismus, 2012Purpose: To measure and report tear osmolarity in premature infants and to assess the change, if any, that occurs with increasing maturity. Methods: In a prospective study of consecutive infants born at less than 37 weeks gestational age undergoing screening for retinopathy of ...

Osmolar Relationships in Infantile Dehydration
Archives of Pediatrics & Adolescent Medicine, 1981We studied serum osmolality in 167 consecutive infants admitted for gastroenteritis with 5% or more dehydration. Osmolality was determined by the freezing-point method in a 0.2-mL sample of serum immediately on admission. Forty-one patients (24.6%) had hypo-osmolar dehydration, with a mean osmolality of 257 mOsm/kg (range, 234 to 270 mOsm/kg).

Osmotic Strength, Osmolality, and Osmolarity
American Journal of Hospital Pharmacy, 1980The confusion that often exists between osmolality and osmolarity is discussed, and the clinical importance of careful distinction between these terms is emphasized. The clinical effects of abnormal osmotic strength of parenteral solutions, methods of determining osmolality and osmolarity, and the practical applications of these concepts are reviewed ...

Tear Film Osmolarity in Epiphora
Ophthalmic Plastic & Reconstructive Surgery, 2012To examine whether patients complaining of epiphora have tears of a lower osmolarity.Sixty-three eyes of 39 patients attending an oculoplastic clinic with a primary complaint of epiphora, had their tear osmolarity recorded. Subjects were excluded if they had current or recent topical eye therapy, active ocular infection or allergy, ocular surface ...

Renal Clearance of an Ionic High-Osmolar and a Nonionic Low-Osmolar Contrast Medium
Investigative Radiology, 1991One hundred patients with normal serum creatinine concentration underwent intravenous urography with either an ionic high-osmolar (diatrizoate) or a nonionic low-osmolar (iopamidol) contrast medium after randomization. Before injection of the contrast medium, a blood sample was drawn for determinating serum creatinine concentration, and a urine sample ...

Tear Osmolarity and Ocular Changes in Pterygium
Cornea, 2012To determine abnormalities in tear osmolarity (TO), tear function, and impression cytology in patients with pterygium and to assess the relationship between the variables.Thirty eyes from 30 patients with primary nasal pterygium and 30 eyes from 30 volunteers without ocular pathologies or dry eye symptoms were enrolled in the present study.
