Abstract
Alcide Allay®, an antimicrobial preparation produced in gel and liquid forms, was evaluated for vaginal toxicity in guinea pigs. 1.0 g/kg Allay® gel or placebo was administered intravaginally once per day over a 30 day period while 2.5 g/kg Allay® liquid (containing either of two concentrations of sodium chlorite and lactic acid as active ingredients) or placebo was applied vaginally three times per day for 10 days. At the conclusion of the studies, hematology, blood and urine clinical chemistry tests and necropsies were performed. RBC, HGB, HCT, MCHC and direct bilirubin increased while CO2, SGPT and CPK decreased in blood after Allay® liquid treatment. Creatinine, urea nitrogen and uric acid in urine were statistically reduced in the liquid groups. Hematology and clinical chemistry parameters were within the normal range of values reported in the literature for guinea pigs, indicating no clinical significance due to drug treatment. Significant differences in organ body/weight ratios were observed between controls and Allay® gel and liquid groups. However, only the livers in the gel study and the vaginas in both studies were changed histologically.
