testicular androgen binding protein (abp) - a parameter of sertoli cell secretory function.using abp as an index of sertoli cell secretory function, several important features of the sertoli cell have emerged: 1. the stimulation of abp production by fsh clearly points to the sertoli cell as a target cell for fsh (3,4,9-16,21,24). 2. the dramatic effects of androgens on abp production both in immature and mature rats also suggest that the sertoli cell is a target cell for androgen (3,12,14,16,25). 3. the striking reduction in abp production in the cryptorchid testis raises the question ...197518322
value of sputum culture in diagnosis of pneumococcal pneumonia.in our laboratory, culture of sputum was extremely useful in diagnosing the etiology of pneumococcal pneumonia. of 31 consecutive patients with bacteremic pneumococcal pneumonia, 29 (94%) had streptococcus pneumoniae cultured from sputum. recovery of pneumococci in culture was enhanced by anaerobic incubation as well as by a plate bile test and an optochin disk on a primary blood agar plate.197718489
