The observed result of matter situation was seen microphotograph Fig. 1 of each experimental group rat endometrium and body of gland section, 2,3,4,5 and 6 between the body of gland form in uterus reached after 30 days.After 30 days, intermembranous matter is more loose in the normal group, and the body of gland flexibility increases, and the glandular epithelium cube has the phenomenon of vacuolation, and a matter is based on spindle cell, and is abundanter, sees Fig. 1 (amplification: 40).The excision group changes more remarkable, the volume atrophy, and the inner membrance attenuation, a matter has fibrosis, sees Fig. 2 (amplification: 40).Use and the invention provides the preparation group all based on simple tubular gland, the body of gland flexibility increases not obvious, brached tubular gland appears in middle dosage (50mg/kg) and heavy dose of group (250mg/kg) individual animal, 100), 4 (amplifications: 100) and 5 (amplifications: 100) the body of gland epithelium is cube or high column physaliphore, sees Fig. 3 (amplification:.Comparative formulation group inner membrance is thicker, and body of gland is more sparse, and part is cystic atrophy, sees Fig. 6 (amplification: 100).Can find out that from these results pharmaceutical preparation provided by the invention is non-stimulated to endometrium, can increase uterus body of gland number, help alleviating climacteric syndrome.
Embodiment 5
Drug level after the measurement patient takes medicine in the serum:
Give 45~55 years old oral preparation A medicine provided by the invention of climacteric women (dosage: disposable oral 100mg), test the concentration of different times blood in human body in liquid Chinese medicine.
With U.S. Diagnostic Systems Laboratories, the special-purpose DSL-10-3500 kit of the EIA serum that Inc produces is measured sodium prasterone sulfate concentration in the blood sample.
Experimental result is seen Fig. 7, and vertical coordinate is a sodium prasterone sulfate concentration among the figure, and abscissa is the time to measuring drug level of taking medicine.As seen from the figure, the very fast rising of sodium prasterone sulfate concentration in the serum reached peak value in about 1 hour behind the oral preparation A provided by the invention, and the half-life is about 12~18 hours.Illustrate that medicine of the present invention is absorbed by the body easily.
Embodiment 6,
Observation contains the pharmaceutical preparation provided by the invention of varigrained sodium prasterone sulfate to 12 clinical effectiveness (Beijing large hospital) of suffering from the menopausal syndrome patient
The patient is divided into two groups, takes medicine B provided by the invention for first group, and another group is taken pharmaceutical preparation A of the present invention; Oral for each person every day 100mg took 3 months.Improvement situation with conventional Kupperman standards of grading and vaginal smear observation menopausal syndrome and senile atrophic vaginitis.
The result show take medicine of the present invention after, menopausal syndrome and senile atrophic vaginitis all have improvement, and the doing well,improving of wherein taking the 6 routine climacteric syndrome symptoms of pharmaceutical preparation A provided by the invention and atrophic vaginitis patient significantly is better than 6 examples of pharmaceutical preparation B provided by the invention.
