| ovariectomy of adult mice exposed prenatally to diethylstilbestrol. | mice exposed prenatally to diethylstilbestrol (des) were ovariectomized at 5-10 weeks of age, or at 15 months of age. they were maintained to old age and studied for incidence of des-related pathologic changes. uterine metaplasia and adenomyosis were not seen after early ovariectomy, but adenomyosis persisted after late ovariectomy. no adenocarcinomas of the genital tract were found in 30 mice ovariectomized early, or in 18 mice ovariectomized at 15 months of age. this result is significantly di ... | 2012 | 3815324 |

| [clinical studies against chronic prostatitis and prostatitis-like syndrome (1). clinico-statistical observation]. | we clinically evaluated 605 cases of chronic prostatis and other resembling disorders. the incidence was 4.34% of all out-patients (7.54% of male patients). the average age was 38.1 years, and many were adolescents. a greater number of out-patients were seen in october, november, and december (p less than 0.01) and june (p less than 0.05). the type of disease was chronic prostatitis in 48.1% (bacterial in 5.3%, non-bacterial in 42.8%) and prostatitis-like syndrome in 51.9%. the incidence among m ... | 2012 | 3389292 |
| [ratio and composition of the plasmalogen and diacylated forms of phospholipids in subcellular fractions of the avian brain]. | studies have been made on the specific content of plasmalogen and diacylated forms of phosphatidylethanolamine and phosphatidylcholine in subcellular fractions (myelin, nuclei, microsomes, mitochondria, synaptosomes) from the brain of pigeons, as well as in the myelin fraction from the brain of the crow corvus cornix and the hawk accipiter gentelis. fatty acid composition and fatty aldehyde composition of these two main phospholipids of the brain were studied in the subcellular fractions obtaine ... | 2012 | 3376631 |
