Hysterectomy with preservation of both ovaries does not result in premature ovarian failure.

This study investigated ovarian function and adnexial pathology following total abdominal hysterectomy with preservation of both ovaries compared with that in a control group. Data from 29 patients who had undergone total abdominal hysterectomy at age < or =40 years and 42 menopausal patients with no previous ovarian pathology were evaluated retrospectively. The mean (+/- SD) age of menopause was 49.7 +/- 1.5 years in the total abdominal hysterectomy group and 50.1 +/- 1.3 years in the control group; this difference was not statistically significant. The incidences of cyst and hydrosalpinx were 31% and 6.9%, respectively, in the total abdominal hysterectomy group and 44.8% and 0%, respectively, in the control group. The increased incidence of cysts in the total abdominal hysterectomy group was statistically significant. In conclusion, patients who undergo total abdominal hysterectomy without oophorectomy do not experience premature menopause. Preservation of the ovaries may avoid the disadvantages of hormone replacement therapy at the expense of a higher risk of developing adnexial pathology.

LC determination of atropine sulfate and scopolamine hydrobromide in pharmaceuticals.

An accurate, simple, reproducible and sensitive method for the determination of atropine sulfate and scopolamine hydrobromide has been developed and validated. Atropine sulfate and scopolamine hydrobromide were separated using a microBondapack C(18) column by isocratic elution with flow rate 1.0 ml/min. The mobile phase composition was methanol, water, formic acid (165:35:1; v/v/v) and pH adjusted 8.3 with triethylamine. The samples were detected at 230 nm using photo-diode array detector. The linear range of detection for atropine sulfate (I) and scopolamine hydrobromide (II) were between 10.38 and 1038 microg/ml with a limit of quantification (LOQ) of 10.38, 10.00 and 1034 microg/ml with an LOQ of 10.00 microg/ml respectively. The linearity, range, peak purity, selectivity, system performance parameters, precision, accuracy, robustness and ruggedness for (I) and (II) were also shown acceptable values.

LC method for the analysis of acetylsalicylic acid, caffeine and codeine phosphate in pharmaceutical preparations.

An accurate, simple, reproducible and sensitive method for the determination of acetylsalicylic acid, caffeine and codeine phosphate has been developed and validated. Acetylsalicylic acid, caffeine and codeine phosphate were separated using a microBondapack C(8) column by isocratic elution with flow rate 1.0 ml/min. The mobile phase composition was 125/125/250/0.5 (v/v) isopropyl alcohol, acetonitrile, water and o-phosphoric acid. The samples were detected at 215 nm using photo-diode array detector. The linear range of detection for acetylsalicylic acid, caffeine and codeine phosphate were between 0.40 and 1000, 0.25 and 250, and 0.48 and 96 microg/ml, respectively. The linearity, range, selectivity, system performance parameters, precision, accuracy, and ruggedness for acetylsalicylic acid, caffeine and codeine phosphate were also shown to have acceptable values.
