| protective efficacy of pneumococcal polysaccharide vaccines. | clinical studies of 6- and 12-valent pneumococcal capsular polysaccharide vaccines were carried out in controlled studies among novice gold miners in south africa. in the studies 1,523 persons received pneumococcal vaccine, and 3,171 were included as controls. in the great majority of subjects given pneumococcal vaccine, antibodies developed against the capsular types included in the vaccine. the 6-valent vaccine afforded 76% reduction in cases of laboratory-verified pneumococcal pneumonia cause ... | 1977 | 21973 |
| dissolution of rabbit zona by sperm acrosomal extract: effect of calcium (1). | the acrosomal extracts from rabbit spermatozoa were more effective in dissolving the zona pellucida of the rabbit ova in the absence than in the presence of ca2+. the extracts had high proteolytic activity but low esterolytic activity at alkaline ph in which ph effective zona hydrolysis occurred. the results suggest that acrosomal proteinases in addition to acrosin may be involved in the zona penetration. | 1979 | 38295 |
| cell-mediated immune response in mice treated with steroidal contraceptives. | the splenomegaly assay (simonsen, 1962) was standardized using different strains of rats and mice. male wistar rat (donor)-female swiss mouse (host) was found to be the suitable combination that could be employed in subsequent experiments to study the potential of contraceptive steroids to alter cmir. the index of splenomegaly appeared to increase in case of mice treated with combination oral contraceptives (ovulen, ovral or enovid). the differences observed, however, neared significance only in ... | 1975 | 55327 |

| sequential hepatic histologic and histochemical changes produced by diethylnitrosamine in the rhesus monkey. | six young adult male rhesus monkeys were given diethylnitrosamine ip for 3-5 years. liver biospies were done monthly. after 6 months, biopsy specimens showed individual hepatocytes and small foci of hepatocytes that were intensely positive for glycogen. during the second and later years, larger foci of such cells developed. in sections stained with hematoxylin and eosin, the glycogen-containing hepatocytes generally appeared unusually clear. some hepatocytes, however, had eosinophilic or basophi ... | 1976 | 187798 |
| the storage lipids in tangier disease. a physical chemical study. | the physical states and phase behavior of the lipids of the spleen, liver, and splenic artery from a 38-yr-old man with tangier disease were studied. many intracellular lipid droplets in the smectic liquid crystalline state were identified by polarizing microscopy in macrophages in both the spleen and liver, but not in the splenic artery. the droplets within individual cells melted sharply over a narrow temperature range, indicating a uniform lipid composition of the droplets of each cell. howev ... | 1977 | 193870 |
| inhibition by somatostatin of adenosine-3',5'-monophosphate stimulated hepatic ribosomal protein synthesis. | somatostatin which inhibits the secretion of various pituitary and intestinal hormones has been suspected to exert these effects by inhibiting adenosine-3',5'-monophosphate accumulation in the respective endocrine gland. our results, obtained by cell free protein synthesis and by sedimentation through sucrose gradients of ribosomes, prepared from rat liver after incubation with cyclic amp and/or somatostatin also suggest this antagonism between somatostatin and cyclic amp. in addition, they indi ... | 1977 | 197300 |

| creatine kinase (ec-no.2.7.3.2) and creatine kinase isoenzymes during pregnancy and labor and in the cord blood. | total ck and ck isoenzyme activity in serum was investigated during pregnancy, labor and after delivery as well as in cord blood. total ck was decreased in the second trimester of pregnancy but increased in late pregnancy. low ck-mb activity in serum was found in patients with early labor pains. ck-bb activity could never be detected during pregnancy. total ck and isoenzyme activity increased after delivery. the rise of total ck and ck-mb in maternal serum is directly correlated with the followi ... | 2004 | 535161 |
